tires JEEP COMPASS 2009 1.G Owners Manual

Airbag Warning Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the LED is not lit during starting, have it
checked. If the light stays on, flickers, or comes on while
driving, have the system checked by an authorized
dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect tread and sidewall for cuts or
cracks. Check the wheel nuts for tightness. Check the
tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check the area under the vehicle after overnight parking
for fuel, engine coolant, oil or other fluid leaks. Also, if
gasoline fumes are detected or fuel, power steering fluid,
transmission fluid or brake fluid leaks are suspected, the
cause should be located and corrected immediately.
70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see Section 7
of this manual. Follow the warnings under the Cool-
ing System Pressure Cap paragraph.
18. Cruise Indicator — If Equipped
This indicator shows that the Electronic Speed
Control System is ON.
19. Cruise Indicator — If Equipped
This indicator shows that the Electronic Speed Control
System is SET to the desired speed.
20. Shift Lever Indicator
This display indicator shows the automatic transmission
shift lever selection.NOTE:You must apply the brakes before shifting from
PARK.
21. Odometer/Trip Odometer Reset Button
Press this button to change the display from odometer to
either of the two trip odometer settings. Trip A or Trip B
will appear when in the trip odometer mode. Push in and
hold the button for two seconds to reset the trip odometer
to 0 miles or kilometers. The odometer must be in Trip
mode to reset.
22. Tire Pressure Monitoring Telltale Light — If
Equipped
Each tire, including the spare (if provided),
should be checked monthly, when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard
UNDERSTANDING YOUR INSTRUMENT PANEL 169
4

or tire inflation pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper 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.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
170 UNDERSTANDING YOUR INSTRUMENT PANEL

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
23. 4WD Indicator — If Equipped
This light indicates the vehicle is in 4WD.24. Odometer/Trip Odometer
This display indicates the total distance the vehicle has
been driven. Also, the cluster will display, replacing the
odometer/trip odometer, vehicle warning messages such
as: “door/gate ajar”, “gASCAP” (loose gas cap), “Lo
tIrE” (display toggles between Lo and tIrE when tire
pressure is low), and “Change Oil” message. Loose gas
cap (gASCAP) will be displayed from the Odometer/Trip
Odometer on all models.
NOTE:If the vehicle is equipped with the optional
Electronic Vehicle Information Center (EVIC) in the in-
strument cluster, all warnings including “door”, and
“gATE” will only be displayed in the EVIC display. For
additional information, refer to “Electronic Vehicle Infor-
mation Center — If Equipped” in Section 3.
United States federal regulations require that upon trans-
fer of vehicle ownership, the seller certify to the pur-
chaser the correct mileage that the vehicle has been

Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:
1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if the road has standing water or puddles.
3. Replace the tires when tread wear indicators first
become visible.
4. Keep the tires properly inflated.
5. Maintain enough distance between your vehicle and
the vehicle in front of you to avoid a collision in a sudden
stop.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
Flowing/Rising Water
WARNING!
Do not drive on or cross a road or a path where water
is flowing and/or rising (as in storm run-off). Flow-
ing water can wear away the road or path’s surface
and cause your vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can carry
your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.

If either of the two hydraulic systems lose normal capa-
bility, the remaining system will still function with some
loss of overall braking effectiveness. This will be evident
by increased pedal travel during application and greater
pedal force required to slow or stop. In addition, if the
malfunction is caused by an internal leak, as the brake
fluid in the master cylinder drops, the brake warning
indicator will light.
WARNING!
Driving a vehicle with the brake light on is danger-
ous. A significant decrease in braking performance or
vehicle stability during braking may occur. It will
take you longer to stop the vehicle or will make your
vehicle harder to control. You could have an accident.
Have the vehicle checked immediately.
Anti-Lock Brake System (ABS) — If Equipped
The ABS provides increased vehicle stability and brake
performance under most braking conditions. The system
automatically “pumps” the brakes during severe braking
conditions to prevent wheel lock-up.
WARNING!
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
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 phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that af-
forded by the condition of the vehicle brakes and
tires or the traction afforded.

ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You may also experience the following when the brake
system goes into Anti-Lock mode:
•the ABS motor running (it may continue to run for a
short time after the stop)
•the clicking sound of solenoid valves
•brake pedal pulsations
•a slight drop or fall away of the brake pedal at the end
of the stop
These are all normal characteristics of ABS.
WARNING!
The Anti-Lock Brake System (ABS) contains sophis-
ticated electronic equipment that may be susceptible
to interference caused by improperly installed or
high output radio transmitting equipment. This in-
terference can cause possible loss of Anti-Lock brak-
ing capability. Installation of such equipment should
be performed by qualified professionals.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.

Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over-steering or under-steering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the over-steering or under-steering condi-
tion. Engine power may also be reduced to help the
vehicle maintain the desired path. ESP uses sensors in the
vehicle to determine the vehicle path intended by the
driver and compares it to the actual path of the vehicle.
When the actual path does not match the intended path,
ESP applies the brake of the appropriate wheel to assist in
counteracting the over-steer or under-steer condition
•Over-steer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Under-steer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESP/TCS Indicator Light
The “ESP/TCS Indicator Light” located in the instrument
cluster, starts to flash as soon as the tires lose traction and
the ESP system becomes active. The “ESP/TCS Indicator
Light” also flashes when TCS is active. If the “ESP/TCS
Indicator Light” begins to flash during acceleration, ease
up on the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and driving to the
prevailing road conditions.
WARNING!
•Electronic Stability Program (ESP) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions.
