Jeep Grand Cherokee (2022 year). Manual in english

140

STARTING AND OPERATING

NOTE:

Automatic lowering of the vehicle into Entry/Exit

can be enabled through the Uconnect Touch

screen Radio by selecting the “Auto Entry/Exit”

setting. If this feature is enabled, the vehicle will

only lower if the gear selector is in PARK, the

terrain switch is in AUTO, the transfer case is in

AUTO and the vehicle level is either in Normal or

Aero Height. The vehicle will not automatically

lower to Entry/Exit height if the air suspension level

is in OR2 or OR1. If the vehicle is equipped with

Intrusion Theft Module (ITM), the lowering will be

suppressed when the ignition is switched OFF and

the door is open to prevent setting the alarm off.
The Selec-Terrain system will automatically change

the vehicle to the proper height based on the

position of the Selec-Terrain switch. The height can

be changed from the default Selec-Terrain setting

by normal use of the air suspension buttons

page 137.

The system requires that the engine be running for

all changes. When lowering the vehicle all of the

doors must be closed. If a door is opened at any

time while the vehicle is lowering the change will

not be completed until the open door(s) is/are

closed.

The Quadra-Lift Air Suspension system uses a

lifting and lowering pattern which keeps the

headlights from incorrectly shining into oncoming

traffic. When raising the vehicle, the rear of the

vehicle will move up first and then the front. When

lowering the vehicle, the front will move down first

and then the rear.
After the engine is turned off, it may be noticed that

the air suspension system operates briefly; this is

normal. The system is correcting the position of the

vehicle to ensure a proper appearance.
To assist with changing a spare tire, the

Quadra-Lift Air Suspension system has a feature

which allows the automatic leveling to be disabled

page 204.

NOTE:

Default Ride Height:



Select Aero Height or Normal Ride Height as the

default for all vehicle speeds and operation.

This is the selected height that the suspension

will level for speed changes (e.g. raising from

Entry/Exit Height at speed, lowering from Off

Road Height at speed, etc.).



Default ride height can be changed by manually

adjusting the ride height switch to Normal Ride

Height or Aero Height and staying in the

selected height for 2.5 seconds. It will be stored

as the default ride height and the height will be

maintained until a new default ride height is

selected.

If equipped with a touchscreen radio, all enabling/

disabling of air suspension features must be done

through the radio

page 204.

FUEL SAVER TECHNOLOGY 5.7L ONLY —

IF EQUIPPED

This feature offers improved fuel economy by

shutting off four of the engine's eight cylinders

during light load and cruise conditions. The system

is automatic with no driver inputs or additional

driving skills required.

NOTE:

This system may take some time to return to full

functionality after a battery disconnect.

POWER STEERING

The electric power steering system provides

enhanced vehicle response and increased ease of

maneuverability in tight spaces. The system will

vary its assistance to provide light effort while

parking and a good feel while driving. If the electric

power steering system experiences a fault that

prevents it from providing assistance, you will still

have the ability to steer the vehicle manually.

Alternate electric power steering efforts (Normal,

Comfort and Sport) can be selected through the

Uconnect System

page 204. If SPORT mode is

selected, steering efforts are optimized for sporty

driving.

If the Electric Power Steering warning

icon is displayed and the “SERVICE

POWER STEERING” or the “POWER

STEERING ASSIST OFF – SERVICE

SYSTEM” message is displayed within the

instrument cluster display, this indicates the

vehicle needs to be taken to the dealer for service

page 110.

NOTE:



Even if the power steering assistance is no

longer operational, it is still possible to steer the

vehicle. Under these conditions there will be a

substantial increase in steering effort, espe

cially at low speeds and during parking maneu

vers.



If the condition persists, see an authorized

dealer for service.

WARNING!

Continued operation with reduced assist could

pose a safety risk to yourself and others. Service

should be obtained as soon as possible.

CRUISE CONTROL SYSTEMS

Your vehicle is equipped with the Adaptive Cruise

Control (ACC) system which will adjust the vehicle

speed up to the preset speed to maintain a

distance with the vehicle ahead.

NOTE:

In vehicles NOT equipped with the Active Driving

Assist (ADA) system:



Fixed Speed Cruise Control can be used when

ACC is not enabled, and functions as normal

cruise control.



Fixed Speed Cruise Control will not detect vehi

cles directly ahead of you. Always be aware of

the feature selected.



Only one Cruise Control feature can operate at a

time. For example, if Fixed Speed Cruise Control

is enabled, Adaptive Cruise Control will be

unavailable, and vice versa.

(Continued)

DAPTIVE

RUISE

ONTROL

(ACC)

Adaptive Cruise Control (ACC) increases the driving

convenience provided by Cruise Control while

traveling on highways and major roadways.

However, it is not a safety system and not designed

to prevent collisions.
ACC will allow you to keep Cruise Control engaged

in light to moderate traffic conditions without the

constant need to reset your Cruise Control. ACC

utilizes a radar sensor and a forward facing

camera designed to detect a vehicle directly ahead

of you.

NOTE:



If the ACC sensor detects a vehicle ahead, ACC

will apply limited braking or acceleration (not to

exceed the original set speed) automatically to

maintain a preset following distance, while

matching the speed of the vehicle ahead.



Any chassis/suspension or tire size modifica

tions to the vehicle will affect the performance

of the Adaptive Cruise Control and Forward Colli

sion Warning system.



In vehicles NOT equipped with the Active Driving

Assist system, Fixed Speed Cruise Control (ACC

not enabled) will not detect vehicles directly

ahead of you. Always be aware of the feature

selected

page 410.

WARNING!



Adaptive Cruise Control (ACC) is a conve

nience system. It is not a substitute for active

driver involvement. It is always the driver’s

responsibility to be attentive of road, traffic,

and weather conditions, vehicle speed,

distance to the vehicle ahead and, most

importantly, brake operation to ensure safe

operation of the vehicle under all road condi

tions. Your complete attention is always

required while driving to maintain safe control

of your vehicle. Failure to follow these warn

ings can result in a collision and death or

serious personal injury.



The ACC system:



Does not react to pedestrians, oncoming

vehicles, and stationary objects (e.g., a

stationary vehicle in a traffic jam or a

disabled vehicle).



Cannot take street, traffic, and weather

conditions into account, and may be

limited upon adverse sight distance condi

tions.



Does not always fully recognize complex

driving conditions, which can result in

wrong or missing distance warnings.



Will bring the vehicle to a complete stop

and hold the vehicle in the stop position

for approximately 10 minutes when

following a vehicle ahead. If the vehicle

ahead does not start moving within

10 minutes, the parking brake will be acti

vated, and the ACC system will be

cancelled.



You should switch off the ACC system:



When driving in fog, heavy rain, heavy

snow, sleet, heavy traffic, and complex

driving situations (i.e., in highway

construction zones).



When entering a turn lane or highway

off-ramp; when driving on roads that are

winding, icy, snow-covered, slippery, or

have steep uphill or downhill slopes.



When towing a trailer up or down steep

slopes.



When circumstances do not allow safe

driving at a constant speed.

U.S. Speed (mph)



Pushing the SET (+), or SET (-) button once will

result in a 1 mph speed adjustment. Each

subsequent tap of the button results in an

adjustment of 1 mph.



If the button is continually pushed, the set

speed will continue to adjust in 5 mph incre

ments until the button is released. The new set

speed is reflected in the instrument cluster

display.

Metric Speed (km/h)



Pushing the SET (+), or SET (-) button once will

result in a 1 km/h speed adjustment. Each

subsequent tap of the button results in an

adjustment of 1 km/h.



If the button is continually pushed, the set

speed will continue to adjust in 10 km/h incre

ments until the button is released. The new set

speed is reflected in the instrument cluster

display.

NOTE:

When you override and push the SET (+) button or

SET (-) button, the new set speed will be the current

speed of the vehicle.

WARNING!

The Resume function should only be used if

traffic and road conditions permit. Resuming a

set speed that is too high or too low for

prevailing traffic and road conditions could

cause the vehicle to accelerate or decelerate too

sharply for safe operation. Failure to follow these

warnings can result in a collision and death or

serious personal injury.

STARTING AND OPERATING

149

When ACC Is Active



When you use the SET (-) button to decelerate, if

the engine’s braking power does not slow the

vehicle sufficiently to reach the set speed, the

brake system will automatically slow the

vehicle.



The ACC system decelerates the vehicle to a full

stop when following the vehicle in front. If your

vehicle follows the vehicle in front to a standstill,

after two seconds the driver will either have to

push the RES (resume) button, or apply the

accelerator pedal to reengage the ACC to the

existing set speed.



The ACC system maintains set speed when

driving uphill and downhill. However, a slight

speed change on moderate hills is normal. In

addition, downshifting may occur while climbing

uphill or descending downhill. This is normal

operation and necessary to maintain set speed.

When driving uphill and downhill, the ACC

system will cancel if the braking temperature

exceeds normal range (overheated).

Setting The Following Distance In ACC

The specified following distance for ACC can be set

by varying the distance setting between four bars

(longest), three bars (long), two bars (medium) and

one bar (short). Using this distance setting and the

vehicle speed, ACC calculates and sets the

distance to the vehicle ahead. This distance

setting appears in the instrument cluster display.

Distance Settings

To increase the distance setting, push the

Distance Increase button and release. Each time

the button is pushed, the distance setting

increases by one bar (longer).
To decrease the distance setting, push the

Distance Decrease button and release. Each time

the button is pushed, the distance setting

decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will

maintain the set speed. If a slower moving vehicle

is detected in the same lane, the instrument

cluster display will show the ACC Set With Target

Detected Indicator Light, and the system will adjust

the vehicle speed automatically to maintain the

distance setting, regardless of the set speed.
The vehicle will then maintain the set distance

until:



The vehicle ahead accelerates to a speed above

the set speed.



The vehicle ahead moves out of your lane or

view of the sensor.



The distance setting is changed.



The system disengages

page 147.

The maximum braking applied by ACC is limited;

however, the driver can always apply the brakes

manually, if necessary.

1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

150

STARTING AND OPERATING

NOTE:

The brake lights will illuminate whenever the ACC

system applies the brakes.
A Proximity Warning will alert the driver if ACC

predicts that its maximum braking level is not

sufficient to maintain the set distance. If this

occurs, a visual alert “BRAKE!” will flash in the

instrument cluster display and a chime will sound

while ACC continues to apply its maximum braking

capacity.

NOTE:

The “BRAKE!” screen in the instrument cluster

display is a warning for the driver to take action

and does not necessarily mean that the Forward

Collision Warning system is applying the brakes

autonomously.

Overtake Aid

When driving with Adaptive Cruise Control (ACC)

engaged and following a vehicle, the system will

provide an additional acceleration up to the ACC

set speed to assist in passing the vehicle. This

additional acceleration is triggered when the driver

utilizes the left turn signal and will only be active

when passing on the left hand side.

ACC Operation At Stop

If the ACC system brings your vehicle to a standstill

while following a vehicle ahead, your vehicle will

resume motion, without any driver interaction, if

the vehicle ahead starts moving within two

seconds of your vehicle coming to a standstill.
If the vehicle in front does not start moving within

two seconds of your vehicle coming to a standstill,

the driver will either have to push the RES (resume)

button, or apply the accelerator pedal to reengage

the ACC to the existing set speed.

NOTE:



If your vehicle is at a standstill for longer than

two seconds, the system will hold brake pres

sure for up to 10 minutes. If no driver action is

taken after the 10 minutes, the Electric Park

Brake will be applied and the ACC system will

cancel.



While ACC is holding your vehicle at a standstill

(or the vehicle is traveling below 3 mph (5 km/

h), and the driver seat belt is unbuckled or the

driver door is opened, the Electric Park Brake

will be applied and the ACC system will cancel.

Display Warnings And Maintenance

“WIPE FRONT RADAR SENSOR IN FRONT OF

VEHICLE” WARNING

The “ACC Unavailable Wipe Front Radar Sensor”

warning will display and a chime will sound when

conditions temporarily limit system performance.
This most often occurs at times of poor visibility,

such as in snow or heavy rain. The ACC system may

also become temporarily blinded due to

obstructions, such as mud, dirt or ice. In these

cases, the instrument cluster display will display

the above message and the system will deactivate.
This message can sometimes be displayed while

driving in highly reflective areas (i.e. ice and snow,

or tunnels with reflective tiles). The ACC system will

recover after the vehicle has left these areas.

Under rare conditions, when the radar is not

tracking any vehicles or objects in its path this

warning may temporarily occur.

WARNING!

When the ACC system is resumed, the driver

must ensure that there are no pedestrians,

vehicles or objects in the path of the vehicle.

Failure to follow these warnings can result in a

collision and death or serious personal injury.

NOTE:

If the “ACC Unavailable Wipe Front Radar Sensor”

warning is active, Fixed Speed Cruise Control is still

available.
If weather conditions are not a factor, the driver

should examine the sensor. It may require cleaning

or removal of an obstruction. The sensor is located

in the center of the vehicle behind the lower grille.
To keep the ACC System operating properly, it is

important to note the following maintenance

items:



Always keep the sensor clean. Carefully wipe the

sensor lens with a soft cloth. Be cautious not to

damage the sensor lens.



Do not remove any screws from the sensor.

Doing so could cause an ACC system malfunc

tion or failure and require a sensor realignment.



If the sensor or front end of the vehicle is

damaged due to a collision, see your authorized

dealer for service.



Do not attach or install any accessories near the

sensor, including transparent material or after

market grilles. Doing so could cause an ACC

system failure or malfunction.

When the condition that deactivated the system is

no longer present, the system will return to the

“Adaptive Cruise Control Off” state and will resume

function by simply reactivating it.

NOTE:



If the “ACC Unavailable Wipe Front Radar

Sensor” message occurs frequently (e.g. more

than once on every trip) without any snow, rain,

mud, or other obstruction, have the radar

sensor realigned at an authorized dealer.



Installing a snowplow, front-end protector, an

aftermarket grille or modifying the grille is not

recommended. Doing so may block the sensor

and inhibit ACC operation.

“CLEAN FRONT WINDSHIELD” WARNING

The “ACC Limited Functionality Clean Front

Windshield” warning will display, and a chime will

sound when conditions temporarily limit system

performance. This most often occurs at times of

poor visibility, such as in snow or heavy rain and

fog. The ACC system may also become temporarily

blinded due to obstructions, such as mud, dirt, or

ice on windshield and fog on the inside of glass. In

these cases, the instrument cluster display will

read “ACC Limited Functionality Clean Front

Windshield” and the system will have degraded

performance.
This message can sometimes be displayed while

driving in adverse weather conditions. The ACC

system will recover after the vehicle has left these

areas. Under rare conditions, when the camera is

not tracking any vehicles or objects in its path this

warning may temporarily occur.

If weather conditions are not a factor, the driver

should examine the windshield and the camera

located on the back side of the inside rearview

mirror. They may require cleaning or removal of an

obstruction.
When the condition that created limited

functionality is no longer present, the system will

return to full functionality.

NOTE:

If the “ACC Limited Functionality Clean Front Wind

shield” message occurs frequently (e.g. more than

once on every trip) without any snow, rain, mud, or

other obstruction, have the windshield and forward

facing camera inspected at an authorized dealer.

SERVICE ACC WARNING

If the system turns off, and the instrument cluster

display reads “ACC Unavailable Service Required”

or “Cruise Unavailable Service Required”, there

may be an internal system fault or a temporary

malfunction that limits ACC functionality. Although

the vehicle is still drivable under normal

conditions, ACC will be temporarily unavailable. If

this occurs, try activating ACC again later, following

an ignition cycle. If the problem persists, see an

authorized dealer.

STARTING AND OPERATING

Precautions While Driving With ACC

In certain driving situations, ACC may have

detection issues. In these cases, ACC may brake

late or unexpectedly. The driver needs to stay alert

and may need to intervene. The following are

examples of these types of situations:

TOWING A TRAILER

Towing a trailer is not recommended when using

ACC.

OFFSET DRIVING

ACC may not detect a vehicle in the same lane that

is offset from your direct line of travel, or a vehicle

merging in from a side lane. There may not be

sufficient distance to the vehicle ahead. The offset

vehicle may move in and out of the line of travel,

which can cause your vehicle to brake or

accelerate unexpectedly.

Offset Driving Condition Example

TURNS AND BENDS

When driving on a curve with ACC engaged, the

system may decrease the vehicle speed and

acceleration for stability reasons, with no vehicle in

front detected. Once the vehicle is out of the curve

the system will resume your original set speed.

This is a part of normal ACC system functionality.

NOTE:

On tight turns ACC performance may be limited.

USING ACC ON HILLS

When driving on hills, ACC may not detect a vehicle

in your lane. Depending on the speed, vehicle load,

traffic conditions, and the steepness of the hills,

ACC performance may be limited.

ACC Hill Example

LANE CHANGING

ACC may not detect a vehicle until it is completely

in the lane in which you are traveling. In the

following lane changing example, ACC has not yet

detected the vehicle changing lanes and it may not

detect the vehicle until it is too late for the ACC

system to take action. ACC may not detect a

vehicle until it is completely in the lane. There may

not be sufficient distance to the lane-changing

vehicle. Always be attentive and ready to apply the

brakes if necessary.

STARTING AND OPERATING

153

Lane Changing Example

NARROW VEHICLES

Some narrow vehicles traveling near the outer

edges of the lane or edging into the lane are not

detected until they have moved fully into the lane.

There may not be sufficient distance to the vehicle

ahead.

Narrow Vehicle Example

STATIONARY OBJECTS AND VEHICLES

ACC does not react to stationary objects or

vehicles. For example, ACC will not react in

situations where the vehicle you are following exits

your lane and the vehicle ahead is stopped in your

lane. It will consider this stopped vehicle a

stationary object as it did not previously detect

movement from it. Always be attentive and ready

to apply the brakes if necessary.

Stationary Object And Stationary Vehicle Example

TRAFFIC SIGN ASSIST SYSTEM —

IF EQUIPPED

The Traffic Sign Assist (TSA) system uses a camera

mounted on the windshield, as well as map data

when the vehicle is equipped with Navigation, to

detect recognizable road signs such as:



Speed limits



School zones



No passing zones

NOTE:



The TSA system will automatically display the

detected road sign using the unit of measure

ment (mph or km/h) selected within the instru

ment cluster display.



If no speed limit signs are detected, the system

will revert to the speed limit signs that are

stored in the Navigation system.



The system always checks the traffic signs indi

cating the current speed limit. The system is

able to recognize and display up to two different

road signs in the instrument cluster display.

These road signs can be found on the Driver

Assist page.

154

STARTING AND OPERATING

CTIVATION

EACTIVATION

The TSA System can be enabled/disabled within

the Uconnect system through the Safety/Driver

Assistance menu. System ON is signaled by road

signs shown on the instrument cluster display.

NOTE:

Even if the system is OFF, the speed limit sign will

be displayed when the driver selects it on the

HOME screen.

RAFFIC

IGN

SSIST

ODES

TSA has three selectable modes of operation that

are available through the Uconnect system

page 204.

Visual
When Visual is selected, the system will alert the

driver when the current speed of the vehicle

exceeds the detected speed limit by showing a

graphic in the instrument cluster display.
Visual + Chime
When Visual + Chime is selected, the system will

alert the driver when the current speed of the

vehicle exceeds the detected speed limit by

showing a graphic in the instrument cluster

display, and by sounding an audible alert. The

audible alert will last for 10 seconds, and the

visual alert will remain on as long as the vehicle is

exceeding the speed limit.

TSA Off
When the TSA system is turned off, the system will

not show any traffic signs (unless selected in the

HOME screen, which will show detected speed

limit signs), and no alerts will be issued to the

driver.

NDICATIONS

ISPLAY

Detected traffic signs are shown in the instrument

cluster display, and can display any combination of

signs at one time (e.g. speed limit, speed limit and

supplemental info, and “Do Not Pass” signs)

depending on what information is available.
When a newly detected speed limit is higher than

the current speed limit, the display will update

along with an “up” arrow.
When a newly detected speed limit is lower than

the current speed limit, the display will update

along with a “down” arrow.

NOTE:

Up or down arrows will be displayed for up to five

seconds.

Traffic Signs Recognized

Supplemental Information
Supplemental information may be displayed along

with a newly detected speed limit indicating

special circumstances the driver should be aware

of. Available supplemental information includes:



School



Construction



Rain



Snow



Fog

1 — Current Speed Limit With Supplemental

Information (School Zone)
2 — Next Speed Limit Detected
3 — No Passing Zone Detected

STARTING AND OPERATING

155

(Continued)

NOTE:

Supplemental information will not be displayed

when the vehicle is ONLY equipped with GPS.
Speed Limit Exceeded
When the vehicle’s speed exceeds the displayed

speed limit by 3 mph (5 km/h), the speed limit sign

on the instrument cluster display will show a red

outline to alert the driver.

ACTIVE DRIVING ASSIST SYSTEM —

IF EQUIPPED

PERATION

The Active Driving Assist (ADA) system is combined

with the Adaptive Cruise Control (ACC) system, and

centers the vehicle in the driving lane while

traveling at speeds up to 90 mph (145 km/h).
For ACC system operating instructions and system

limitations, see

page 145.

NOTE:



The driver should always obey traffic laws and

speed limits. Never drive above applicable

speed limit restrictions.



The driver can override ADA at any time by

braking, accelerating, or steering the vehicle.

Just like ACC, ADA will maintain a set speed as long

as the set distance between your vehicle and the

vehicle in front is maintained. ADA will also keep

your vehicle centered between the lane lines, and

monitor for other vehicles in adjacent lanes by

utilizing the Blind Spot Monitoring sensors.
Two types of Active Driving Assist systems are

available:



Base ADA system



Hands-Free ADA system

Base Active Driving Assist System — If Equipped
The Base ADA system uses sensors within the

steering wheel to measure driver attentiveness,

and requires that the driver have their hands on

the steering wheel at all times.
The system will generally aim to keep the vehicle

centered in the lane, but when the driver turns the

steering wheel (e.g. to move further away from a

large vehicle in the next lane) the system will

reduce its control and enter "co-steering" mode.

While in co-steering mode, the system will provide

reduced assistance and allow the driver to control

the path of the vehicle. Once the driver stops

providing input to the steering wheel, the system

will require a few seconds to fully resume lane

centering assistance, especially during curves.

CAUTION!



Traffic Sign Assist is designed to assist the

driver and not to substitute the driver. It is the

driver’s responsibility to continue to monitor

the vehicle speed.



Functionality may be limited or the system

may not work if the sensor is obstructed.



The system may have limited operation or not

work at all in weather conditions such as

heavy rain, hail, and thick fog. Strong light

contrasts can influence the recognition capa

bility of the sensor.



The area surrounding the sensor must not be

covered with stickers or any other object.



Do not tamper or perform any operations in

the area of the windshield glass directly

surrounding the sensor.



Clean foreign matters such as bird droppings,

insects, snow or ice on the windshield. Use

specific detergents and clean cloths to avoid

scratching the windshield.
