2008 JEEP COMPASS engine overheat

13. Engine Coolant Temperature Warning Light
This light warns of an overheated engine condi-
tion. If the engine is critically hot, a warning chime
will sound 10 times. After the chime turns off, the
engine will still be critically hot until the light goes out.
14. Brake System Warning Light
This light monitors various brake functions, in-
cluding brake fluid level and parking brake appli-
cation. If the brake light turns on, it may indicate that the
parking brake is applied, there is a low brake fluid level
or there is a problem with the anti-lock brake system.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. Failure of either half of the dual brake system is
indicated by the Brake Warning Light which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.NOTE:The light may flash momentarily during sharp
cornering maneuvers which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the brake light on is danger-
ous. Part of the brake system may have failed. It will
take longer to stop the vehicle. You could have an
accident. Have the vehicle checked immediately.
Vehicles equipped with Anti-Lock brakes (ABS), are also
equipped with Electronic Brake Force Distribution (EBD).

the pointer drops back into the normal range. If the
pointer remains on theH(red) mark, turn the engine off
immediately and call for service.
There are steps that you can take to slow down an
impending overheat condition. If your air conditioning is
on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to Floor and
the Fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.

Autostick operation is activated in the9D9position by
moving the shift lever side to side. Moving the lever to
the (+) side will activate Autostick and shift up to the
next higher manual ratio, unless you are already operat-
ing in or near overdrive in which case, 6th ratio will be
selected. In like manner, moving the lever to (-) will
activate Autostick and shift to the next lower manual
ratio. After Autostick is activated, the manual ratio
selected is displayed in the transmission ratio display
and tipping the lever to the (+) or (-) direction will cause
an upshift or downshift by one ratio.
Autostick is deactivated:
²By holding the lever to (+) momentarily.
²When the shift lever is shifted out of9D.9
²When in 6 position, touching the lever to the right.
²When heavy Anti-lock brake system (ABS) application
is detected.
Autostick General Information
²
If a ratio other than 1st is selected and the vehicle is
brought to a stop, the transaxle control logic will
automatically select the 1st gear ratio.
²If a low range is selected and the engine accelerates to
the rev limit, the transaxle will automatically select the
next higher ratio.
²If a downshift would cause the engine to overspeed,
that shift will not occur until it is safe for the engine.
Mostly the CVT will stay in the manually selected
ratio, however.
²If the system detects powertrain overheating, the
transmission will revert to the automatic shift mode
and remain in that mode until the powertrain cools off.
²If the system detects a problem it will disable the
Autostick mode and the transmission will return to the
automatic mode until the problem is corrected.

²An 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 dealer for service assistance.
²The 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:
²Do 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.

HAZARD WARNING FLASHER
The flasher switch is located on the instrument
panel, below the radio. Depress the switch and
both cluster indicators and all front and rear
directional signals will flash. Depress the
switch again to turn Hazard Warning Flashers
off.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed and the vehicle locked.
NOTE:With extended use, the flasher may wear down
your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
²On the highways Ð Slow down.
²In city traffic Ð While stopped, put transaxle in
neutral, but do not increase engine idle speed.
If the pointer rises to theH(red) mark, the instrument
cluster will sound a chime. Pull over and stop the vehicle
with the engine at idle, when safe. Turn off the air
conditioning and wait until the pointer drops back into

the normal range. If the pointer remains on the H (red)
mark for more than a minute, turn the engine off imme-
diately and call for service.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
the fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads ªHº, pull
over and stop the vehicle with the engine at idle,
when safe. Turn the air conditioner off and wait until
the pointer drops back into the normal range. After
appropriate action has been taken, if the pointer
remains on the ªHº, turn the engine off immediately,
and call for service.

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 Section 7, Maintenance, 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!
²Being 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.
²The 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.
