Jeep Commander (2010 year). Instruction

CAUTION!

• The TPMS has been optimized for the original

equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement
equipment that is not of the same size, type, and/or
style. Aftermarket wheels can cause sensor dam-
age. Do not use aftermarket tire sealants or balance
beads if your vehicle is equipped with a TPMS, as
damage to the sensors may result.

• After inspecting or adjusting the tire pressure

always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.

NOTE:

• The TPMS is not intended to replace normal tire care

and maintenance, or to provide warning of a tire
failure or condition.

• The TPMS should not be used as a tire pressure gauge

while adjusting your tire pressure.

• Driving on a significantly under-inflated tire causes

the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.

• The TPMS is not a substitute for proper tire mainte-

nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
Light.

STARTING AND OPERATING

305

• Seasonal temperature changes will affect tire pressure,

and the TPMS will monitor the actual tire pressure in
the tire.

Base System

The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim-mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.

NOTE:

It is particularly important, for you to regularly

check the tire pressure in all of your tires, and to maintain
the proper pressure.

The TPMS consists of the following components:

• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light

A tire pressure monitoring sensor is located in the spare
wheel, if the vehicle is equipped with a matching full-size
spare wheel and tire assembly. The matching full-size
spare tire can be used in place of any of the four road
tires. A low spare tire will not cause the Tire Pressure
Monitoring Telltale Light to illuminate, a warning mes-
sage to appear, or the chime to sound.

The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, a “TIRE LOW
PRESSURE” message will display in the instru-

ment cluster for 60 seconds, and an audible chime will be
activated, when one or more of the four active road tire
pressures are low. Should this occur, you should stop as
soon as possible, check the inflation pressure of each tire
on your vehicle, and inflate each tire to the vehicle’s
recommended cold placard pressure value. The system
will automatically update and the Tire Pressure Monitor-
ing Telltale Light will extinguish, once the updated tire

306

STARTING AND OPERATING

pressures have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) to
receive this information.

The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. In addition, a “CHECK TPM
SYSTEM” message will be displayed for 75 seconds when
a system fault is detected, and a chime will sound. If the
ignition key is cycled, this sequence will repeat, provid-
ing the system fault still exists. The Tire Pressure Moni-
toring Telltale Light will turn off when the fault condition
no longer exists. A system fault can occur by any of the
following:

1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.

2. Installing some form of aftermarket window tinting
that affects radio wave signals.

3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.

NOTE:

• If your vehicle is equipped with a matching full-size

spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS). In the event that
the matching full-size spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the Tire Pressure Monitoring Telltale Light to be
ON, a “TIRE LOW PRESSURE” message will be
displayed in the instrument cluster for 60 seconds, and
a chime to sound. Driving the vehicle for up to
20 minutes above 15 mph (24 km/h) will turn OFF the
Tire Pressure Monitoring Telltale Light as long as none
of the road tires are below the low pressure warning
threshold.

STARTING AND OPERATING

307

• If your vehicle is not equipped with a matching

full-size spare wheel and tire assembly, it does not
have a tire pressure monitoring sensor in the spare tire.
The TPMS will not be able to monitor the tire pressure.
If you install the spare tire, in place of a road tire, that
has a pressure below the low-pressure warning limit,
upon the next ignition key cycle, a chime will sound, a
“TIRE LOW PRESSURE” message will be displayed in
the instrument cluster for 60 seconds, and the Tire
Pressure Monitoring Telltale Light will turn ON. After
driving the vehicle for up to 20 minutes above 15 mph
(25 km/h), the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on
solid. In addition, a “CHECK TPM SYSTEM” message
will be displayed for 75 seconds. For each subsequent
ignition key cycle, a chime will sound, a “CHECK
TPM SYSTEM” message will be displayed for 75 sec-
onds, and the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on

solid. Once you repair or replace the original road tire,
and reinstall it on the vehicle in place of the spare tire,
the TPMS will update automatically and the Tire
Pressure Monitoring Telltale Light will turn OFF, as
long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to
receive this information.

Premium System — If Equipped

NOTE:

It is particularly important, for you to regularly

check the tire pressure in all of your tires and to maintain
the proper pressure.

308

STARTING AND OPERATING

The Tire Pressure Monitor System (TPMS) consists of the
following components:

• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Three Trigger Modules (mounted in three of the four

wheel wells)

• Various Tire Pressure Monitoring System Messages,

which display in the Electronic Vehicle Information
Center (EVIC), and a graphic displaying tire pressures

• Tire Pressure Monitoring Telltale Light

tires. A low spare tire will set the “SPARE LOW PRES-
SURE” message, but it will not cause the Tire Pressure
Monitoring Telltale Light to illuminate or the chime to
sound.

Tire Pressure Monitoring Low Pressure Warnings

The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, and an au-
dible chime will be activated, when one or more of

the four active road tire pressures are low. In addition, the
EVIC will display one or more Low Pressure messages
(Left Front, Left Rear, Right Front, Right Rear) for three
seconds, and a graphic display of the pressure value(s)
with the low tire(s) “flashing.” Refer to “Electronic Ve-
hicle Information Center (EVIC)” in Section 4 of this
manual.

STARTING AND OPERATING

309

NOTE:

Your system can be set to display pressure units

in PSI, kPa, or BAR.

Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is “flashing” on the graphic
display to the vehicle’s recommended cold tire pressure.

The system will automatically update, the graphic dis-
play of the pressure value(s) will stop “flashing,” and the
Tire Pressure Monitoring Telltale Light will extinguish
once the updated tire pressure(s) have been received. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.

CHECK TPM SYSTEM Warning
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. The EVIC will display a “CHECK TPM SYS-
TEM” message for three seconds. This message is then
followed by a graphic display, with “- -“ in place of the
pressure value(s), indicating which Tire Pressure Moni-
toring Sensor(s) is not being received.

NOTE:

Your system can be set to display pressure units

in PSI, kPa, or BAR.

310

STARTING AND OPERATING

If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, the

⬙CHECK TPM SYSTEM⬙

message will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following:

1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.

2. Installing some form of aftermarket window tinting
that affects radio wave signals.

3. Lots of snow or ice around the wheels or wheel
housings.

4. Using tire chains on the vehicle.

5. Using wheels/tires not equipped with TPM sensors.

The EVIC will also display a

⬙CHECK TPM SYSTEM⬙

message for three seconds when a system fault is de-
tected possibly related to the trigger component. In this
case, the

⬙CHECK TPM SYSTEM⬙ message is then fol-

lowed by a graphic display, with pressure values still
shown. This indicates the pressure values are still being

311

received from the TPM Sensors. However, the system still
needs to be serviced as long as the

⬙CHECK TPM

SYSTEM

⬙ message exists.

NOTE:

• If your vehicle is equipped with a matching full-size

spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS). In the event that
the matching full-size spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the Tire Pressure Monitoring Telltale Light to be
ON, a chime to sound, a Low Pressure message to
appear in the EVIC, and the graphic display will still
show the low tire pressure value “flashing.” Driving
the vehicle for up to 20 minutes above 15 mph
(24 km/h) will turn OFF the Tire Pressure Monitoring
Telltale Light as long as none of road tires are below
the low pressure warning threshold. The EVIC will
also display a “SPARE LOW PRESSURE” message,

and the graphic display will show a tire pressure value
in place of the “flashing” low tire pressure value.

• If your vehicle is not equipped with a matching

full-size spare wheel and tire assembly, it does not
have a tire pressure monitoring sensor in the spare tire.
The TPMS will not be able to monitor the tire pressure.
If you install the spare tire in place of a road tire that
has a pressure below the low-pressure warning limit,
upon the next ignition key cycle, the Tire Pressure
Monitoring Telltale Light will remain ON, a chime will
sound, and the EVIC will still display a “flashing”
pressure value in the graphic display. After driving the
vehicle for up to 20 minutes above 15 mph (24 km/h),
the Tire Pressure Monitoring Telltale Light will flash
on and off for 75 seconds and then remain on solid. In
addition, the EVIC will display a “CHECK TPM
SYSTEM

⬙ message for three seconds and then display

dashes (- -) in place of the pressure value. For each
subsequent ignition key cycle, a chime will sound, the

312

STARTING AND OPERATING

Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and then remain on solid, and
the EVIC will display a

message for three seconds and then display dashes (- -)
in place of the pressure value. Once you repair or
replace the original road tire, and reinstall it on the
vehicle in place of the spare tire, the TPMS will update
automatically.

In addition, the Tire Pressure Monitoring Telltale Light
will turn OFF and the graphic in the EVIC will display a
new pressure value instead of dashes (- -), as long as no
tire pressure is below the low-pressure warning limit in
any of the four active road tires. The vehicle may need to
be driven for up to 20 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this information.

FUEL REQUIREMENTS

3.7 Engine

All engines (except 5.7L engines) are de-
signed to meet all emissions regulations
and provide excellent fuel economy and
performance when using high-quality un-
leaded “regular” gasoline having an oc-
tane rating of 87. The use of premium

gasoline is not recommended, as it will not provide any
benefit over regular gasoline in these engines.

5.7L Engine

The 5.7L engine is designed to meet all
emissions regulations and provide satisfac-
tory fuel economy and performance when
using high-quality unleaded gasoline hav-
ing an octane range of 87 to 89. The manu-
facturer recommends the use of 89 octane

for optimum performance. The use of premium gasoline
is not recommended, as it will not provide any benefit
over regular gasoline in these engines.

Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage, and immediate service is
required.

Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of gasoline before consid-
ering service for the vehicle.

Over 40 auto manufacturers worldwide have issued and
endorsed consistent gasoline specifications (the World-
wide Fuel Charter, WWFC) to define fuel properties
necessary to deliver enhanced emissions, performance,
and durability for your vehicle. The manufacturer recom-
mends the use of gasoline that meets the WWFC speci-
fications, if they are available.

314

STARTING AND OPERATING

Reformulated Gasoline

Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline.”

Reformulated gasoline contains oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.

The manufacturer supports the use of reformulated gaso-
line. Properly blended reformulated gasoline will pro-
vide excellent performance and durability of engine and
fuel system components.

Gasoline/Oxygenate Blends

Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% Ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.

CAUTION!

DO NOT use gasoline containing Methanol. Use of
these blends may result in starting and drivability
problems and may damage critical fuel system com-
ponents.

Problems that result from using Methanol/gasoline
blends are not the responsibility of the manufacturer.
While MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.

E-85 Usage In Non-Flex Fuel Vehicles

Non-FFV vehicles are compatible with gasoline contain-
ing 10% Ethanol (E10). Gasoline with higher Ethanol
content may void the vehicle’s warranty.

If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:

• operate in a lean mode

STARTING AND OPERATING

315

• OBD II “Malfunction Indicator Light” on
• poor engine performance
• poor cold start and cold drivability
• increased risk for fuel system component corrosion

To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:

• drain the fuel tank (see your authorized dealer)
• change the engine oil and oil filter
• disconnect and reconnect the battery to reset the

engine controller memory

More extensive repairs will be required for prolonged
exposure to E-85 fuel.

MMT In Gasoline

MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline

blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emission system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer if the
gasoline contains MMT.

It is even more important to look for gasoline without
MMT in Canada, because MMT can be used at levels
higher than those allowed in the United States.

MMT is prohibited in Federal and California reformu-
lated gasoline.

Materials Added To Fuel

All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal

316

STARTING AND OPERATING

conditions and would result in additional cost. Therefore,
you should not have to add anything to the fuel.

Fuel System Cautions

CAUTION!

Follow these guidelines to maintain your vehicle’s
performance:

• The use of leaded gas is prohibited by Federal law.

Using leaded gasoline can impair engine performance
and damage the emission control system.

• An out-of-tune engine, or certain fuel or ignition

malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.

• The use of fuel additives which are now being sold as

octane enhancers is not recommended. Most of these
products contain high concentrations of Methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.

NOTE:

Intentional tampering with emissions control

systems can result in civil penalties being assessed
against you.

Carbon Monoxide Warnings

WARNING!

Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning.

STARTING AND OPERATING

317

• Do not inhale exhaust gases. They contain carbon

monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.

• Guard against carbon monoxide with proper mainte-

nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.

• Keep the liftgate closed when driving your vehicle to

prevent carbon monoxide and other poisonous ex-
haust gases from entering the vehicle.

ADDING FUEL

Fuel Filler Cap (Gas Cap)

The gas cap is located behind the fuel filler door, on the
driver’s side of the vehicle. If the gas cap is lost or
damaged, be sure the replacement cap is for use with this
vehicle.

Fuel Filler Cap

318

STARTING AND OPERATING

CAUTION!

• Damage to the fuel system or emission control

system could result from using an improper fuel
cap (gas cap). A poorly fitting cap could let impu-
rities into the fuel system. Also, a poorly fitting
aftermarket cap can cause the “Malfunction Indi-
cator Light” (MIL) to illuminate, due to fuel vapors
escaping from the system.

• A poorly fitting gas cap may cause the MIL to turn

on.

• To avoid fuel spillage and overfilling, do not “top

off” the fuel tank after filling.

NOTE:

When the fuel nozzle “clicks” or shuts off, the

fuel tank is full.

WARNING!

• Never have any smoking materials lit in or near

the vehicle when the gas cap is removed or the
tank filled.

• Never add fuel when the engine is running. This is

in violation of most state and federal fire regula-
tions and will cause the MIL to turn on.

NOTE:

Tighten the gas cap about one–quarter turn until

you hear one click. This is an indication that cap is
properly tightened.

If the gas cap is not tighten properly, the MIL will come
on. Be sure the gas cap is tightened every time the vehicle
is refueled.

STARTING AND OPERATING

319

Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“CHECK GASCAP” message will be displayed in the
EVIC (Electronic Vehicle Information Center). Refer to
“Electronic Vehicle Information Center” in Section 4 of
this manual. Tighten the fuel filler cap until a “clicking”
sound is heard. This is an indication that the fuel filler
cap is properly tightened. Refer to “Onboard Diagnostic
System — OBDII” in Section 7 of this manual for more
information.

WARNING!

A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.

CAUTION!

Damage to the fuel system or emission control sys-
tem could result from using an improper fuel tank
filler cap (gas cap). A poorly fitting cap could let
impurities into the fuel system.

WARNING!

• Never add fuel when the engine is running.
• Never have any smoking materials lit in or near

the vehicle when the fuel cap is removed or the
tank filled.
