RADIO OPERATION AND MOBILE PHONES

Under certain conditions, the mobile phone being

on in your vehicle can cause erratic or noisy

performance from your radio. This condition may

be lessened or eliminated by repositioning the

mobile phone within the vehicle. This condition is

not harmful to the radio. If your radio performance

does not satisfactorily improve from repositioning

the mobile phone, it is recommended that the

volume be turned down or off during mobile phone

operation when not using the Uconnect system.

Exposure to Radio Frequency Radiation
The radiated output power of the internal wireless

SAFETY FEATURES

YSTEM

(ABS)

The ABS provides increased vehicle stability and

brake performance under most braking conditions.

The system automatically prevents wheel lock and

enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that

the ABS is working properly each time the vehicle

is started and driven. During this self-check, you

may hear a slight clicking sound as well as some

related motor noises.
The ABS is activated during braking when the

system detects one or more wheels are beginning

to lock. Road conditions such as ice, snow, gravel,

bumps, railroad tracks, loose debris, or panic stops

may increase the likelihood of ABS activation(s).
You also may experience the following normal

characteristics when the ABS activates:



ABS motor noise or clicking sounds (you may

continue to hear for a short time after the stop)



Brake pedal pulsations



A slight drop of the brake pedal at the end of the

stop

The ABS is designed to function with the Original

Equipment Manufacturer (OEM) tires. Modification

may result in degraded ABS performance.

Anti-Lock Brake System (ABS) Warning

Light

The yellow ABS Warning Light will turn on when the

ignition is placed in the ON/RUN mode and may

stay on for as long as four seconds.
If the ABS Warning Light remains on or comes on

while driving, it indicates that the anti-lock portion

of the brake system is not functioning and that

service is required. However, the conventional

brake system will continue to operate normally if

the ABS Warning Light is on.

WARNING!



The ABS contains sophisticated electronic

equipment that may be susceptible to interfer

ence caused by improperly installed or high

output radio transmitting equipment. This

interference can cause possible loss of

anti-lock braking capability. Installation of

such equipment should be performed by qual

ified professionals.



Pumping of the Anti-Lock Brakes will diminish

their effectiveness and may lead to a collision.

Pumping makes the stopping distance longer.

Just press firmly on your brake pedal when you

need to slow down or stop.



The ABS cannot prevent the natural laws of

physics from acting on the vehicle, nor can it

increase braking or steering efficiency beyond

that afforded by the condition of the vehicle

brakes and tires or the traction afforded.



The ABS cannot prevent collisions, including

those resulting from excessive speed in turns,

following another vehicle too closely, or hydro

planing.



The capabilities of an ABS equipped vehicle

must never be exploited in a reckless or

dangerous manner that could jeopardize the

user’s safety or the safety of others.

WARNING!

250

SAFETY

If the ABS Warning Light is on, the brake system

should be serviced as soon as possible to restore

the benefits of Anti-Lock Brakes. If the ABS

Warning Light does not come on when the ignition

is placed in the ON/RUN mode, have the light

repaired as soon as possible.

ROWSY

RIVER

ETECTION

(DDD) —

QUIPPED

DDD detects when the driver is feeling fatigued

and warns the driver to pull over and take a break.

To Activate/Deactivate

DDD can be activated and deactivated through the

Uconnect system by selecting the following in

order:
1. “Safety & Driving Assistance”
2. “Drowsy Driver Detection”

System Intervention

Using feedback obtained from the driver’s steering

patterns, any buttons/switches that are pressed,

and from the front camera, the system implements

two operating logics:



The first operating logic takes the driving style

into account, observing the road and detecting

to what extent the driver can continue driving

with few lane crossing events.



The second operating logic measures the time

spent behind the wheel with the vehicle speed

above 40 mph (60 km/h) and below 110 mph

(180 km/h).

NOTE:

If the conditions described above are not detected

continuously during the entire driving period, the

“Drowsy Driver” message may be displayed later

than two or three hours. If the driving style indi

cates that the driver is unable to follow the road

trajectory and respect the horizontal lane

markings, the red symbol will appear on the

instrument cluster display to suggest that the

driver should stop for a break. An audible signal

will also sound.

If the driver accepts the suggestion provided by the

system by pushing the “OK” button on the left side

of the steering wheel, the message will disappear

from the display.
If the driver does not acknowledge the warning, it

will be displayed for 60 seconds and then

disappear.
NOTE:

In the event of a DDD system failure, a dedicated

message will appear in the instrument cluster

display.

DDD Warning Message

WARNING!

The DDD system is an aid for driving and does

not relieve the driver of the responsibility of

driving the vehicle. If you experience fatigue

while driving, pull over safely for a break without

waiting for the DDD to intervene. Only return to

the road when you are in the right physical and

mental condition to prevent endangering

yourself and other drivers.

Brake Assist System (BAS)

The BAS is designed to optimize the vehicle’s

braking capability during emergency braking

maneuvers. The system detects an emergency

braking situation by sensing the rate and amount

of brake application and then applies optimum

pressure to the brakes. This can help reduce

braking distances. The BAS complements the

Anti-Lock Brake System (ABS). Applying the brakes

very quickly results in the best BAS assistance. To

receive the benefit of the system, you must apply

continuous braking pressure during the stopping

sequence (do not “pump” the brakes). Do not

reduce brake pedal pressure unless braking is no

longer desired. Once the brake pedal is released,

the BAS is deactivated.

Brake System Warning Light

The red Brake System Warning Light will turn on

when the ignition is placed in the ON/RUN mode

and may stay on for as long as four seconds.
If the Brake System Warning Light remains on or

comes on while driving, it indicates that the brake

system is not functioning properly and that

immediate service is required. If the Brake System

Warning Light does not come on when the ignition

is placed in the ON/RUN mode, have the light

repaired as soon as possible.

WARNING!

The Brake Assist System (BAS) cannot prevent

the natural laws of physics from acting on the

vehicle, nor can it increase the traction afforded

by prevailing road conditions. BAS cannot

prevent collisions, including those resulting from

excessive speed in turns, driving on very slippery

surfaces, or hydroplaning. The capabilities of a

BAS-equipped vehicle must never be exploited in

a reckless or dangerous manner, which could

jeopardize the user's safety or the safety of

others.
