tire pressure JEEP COMPASS 2009 1.G Owner's Guide

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, theCHECK TPM SYSTEM
text message will not be present, and a pressure value
will be displayed instead of dashes. A system fault can
occur with any of the following scenarios:
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. 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:Your vehicle is equipped with a compact spare
wheel and tire assembly.
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not monitor
the tire pressure in the compact spare tire.
2. If you install the compact 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 and the Tire Pressure Monitoring Telltale Light
will still turn ON due to the low tire.
3. However, after driving the vehicle for up to 20 min-
utes above 15 mph (25 km/h), the Tire Pressure Moni-
toring Telltale Light will flash on and off for 75 seconds
and then remain on solid.
306 STARTING AND OPERATING

4. For each subsequent ignition key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on
solid.
5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact 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
(25 km/h) in order for the TPMS to receive this
information.

FUEL REQUIREMENTS
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high-quality regular
unleaded gasoline with an octane rating of
87. The use of premium gasoline is not
recommended. The use of premium gaso-
line will provide no benefit over high-quality regular
gasolines and, in some circumstances may result in
poorer performance.

Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle, for
all loading conditions.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Overloading
The load carrying components (springs, tires, wheels,
etc.) of your vehicle will provide satisfactory service as
long as you do not exceed the GVWR.The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier suspension compo-
nents do not necessarily increase the vehicle’s GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight. Store heavier items down low and be sure you
distribute their weight as evenly as possible. Stow all
loose items securely before driving. Improper weight
distribution can have an adverse effect on the way your
vehicle steers and handles, and the way the brakes
operate.

Towing Requirements — Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in this section for proper
tire inflation procedures.
Also, check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires–General Information” in
this section for the proper inspection procedure.
When replacing tires, refer to “Tires–General Informa-
tion” in this section for proper tire replacement proce-
dures. Replacing tires with a higher load carrying
capacity will not increase the vehicle’s GVWR and
GAWR limits.
Towing Requirements — Trailer Brakes

Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
2,000 lbs (907 kg).

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 a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to “Maintenance”, Section 7 of
this manual. Follow the warnings under the “Cooling
System Pressure Cap” paragraph.
AUTOMATIC TRANSAXLE OVERHEATING
During sustained high speed driving or trailer towing up
long grades on hot days, the automatic transaxle oil may
become too hot.
If this happens, the transmission overheat in-
dicator light will come on, and the vehicle will
slow slightly until the automatic transaxle
cools down enough to allow a return to therequested speed. If the high speed is maintained, the
overheating will reoccur, as before, in a cyclic fashion.
JACKING AND TIRE CHANGING
WARNING!
•Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you
need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
•The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.
332 WHAT TO DO IN EMERGENCIES

WARNING!
A loose tire thrown forward in a collision or hard
stop could injure the occupants in the vehicle. Have
the deflated (flat) tire repaired or replaced immedi-
ately.
11. Check the tire pressure as soon as possible. Correct
the tire pressure as required.
JUMP-STARTING PROCEDURES
WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is on. You can be hurt by the fan.
(Continued)
WARNING! (Continued)
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transaxle cannot be started this way and may be
damaged. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite
and damage the converter and vehicle. If the
vehicle has a discharged battery, booster cables
may be used to obtain a start from another vehicle.
This type of start can be dangerous if done im-
properly, so follow this procedure carefully.
•Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make
an inadvertent electrical contact. You could be
seriously injured.
NOTE: Disconnecting the battery with the ignition in
the ON position will cause vehicles with an automatic
338 WHAT TO DO IN EMERGENCIES

6. If the vehicle is equipped with a Sentry KeyImmo-
bilizer, turn the ignition switch to the ON position for
three seconds before moving the ignition switch to the
START position.
7. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, then start the
engine in the vehicle with the discharged battery.
8. When removing the jumper cables, reverse the se-
quence exactly. Be careful of the moving belts and fan.
FREEING A STUCK VEHICLE
NOTE:If your vehicle is equipped with Traction Con-
trol or ESP, turn the system OFF before attempting to
“rock” the vehicle.
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around thefront wheels. Then shift back and forth between RE-
VERSE and 1st gear. Usually the least accelerator pedal
pressure to maintain the rocking motion without spin-
ning the wheels is most effective.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause axle, tire
damage or failure. A tire could explode and injure
someone. Do not spin your vehicle’s wheels faster
than 30 mph (48 km/h) or for longer than 30 seconds
continuously without stopping when you are stuck.
And don’t let anyone near a spinning wheel, no
matter what the speed.
340 WHAT TO DO IN EMERGENCIES

WARNING! (Continued)
•You or others can be badly burned by hot coolant
or steam from your radiator. If you see or hear
steam coming from under the hood, do not open
the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap
when the radiator is hot.
Coolant Checks
Check engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or
rusty in appearance, the system should be drained,
flushed and refilled with fresh engine coolant (anti-
freeze). Check the front of the A/C condenser for any
accumulation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the
face of the condenser.Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.
Cooling System — Drain, Flush And Refill
Refer to the “Maintenance Schedule” in Section 8 for
proper maintenance intervals.
If the engine coolant (antifreeze) is dirty or contains a
considerable amount of sediment, clean and flush with a
reliable cooling system cleaner. Follow with a thorough
rinsing to remove all deposits and chemicals. Properly
dispose of old engine coolant (antifreeze).
Selection Of Coolant
Refer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.
