2008 JEEP COMPASS Owners Manual

WARNING!
Battery fluid is a corrosive acid solution; do not allow
battery fluid to contact eyes, skin or clothing. Don't
lean over battery when attaching clamps or allow the
clamps to touch each other. If acid splashes in eyes or
on skin, flush the contaminated area immediately
with large quantities of water.
A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away from
the vent holes. Do not use a booster battery or any
other booster source with an output that exceeds 12
volts.
6. Connect the other cable, first to the negative terminal
of the booster battery and then to the negative terminal of
the discharged battery. Make sure you have a good
contact.7. If the vehicle is equipped with Sentry Key Immobi-
lizer, turn the ignition switch to the ON position for 3
seconds before moving the ignition switch to the START
position.
8. 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.
9. 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
ªrockº 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 the
front wheels. Then shift back and forth between Reverse

and First gear. Usually the least accelerator pedal pres-
sure to maintain the rocking motion without spinning 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.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transaxle overheating and failure. It can
also damage the tires. Do not spin the wheels above
30 mph (48 km/h). Do not spin the wheels continu-
ously for more than 30 seconds.
TOWING A DISABLED VEHICLE
With Ignition Key
Automatic And Manual Transaxle
Front-wheel-drive vehicles must have the front wheels
elevated; Four-wheel-drive vehicles must be hauled on a
flatbed truck.
306 WHAT TO DO IN EMERGENCIES

All Transaxles
CAUTION!
If the vehicle being towed requires steering, the
ignition switch must be in the ACCESSORY posi-
tion, not in the LOCK position.
Do not attempt to use sling type equipment when
towing. When securing vehicle to flat bed truck, do
not attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
If it is necessary to use the accessories while being towed
(wipers, defrosters, etc.), the key must be in the ON
position, not the ACCESSORY position. Make certain the
transaxle remains in NEUTRAL.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. A dolly should be
used under the front wheels if the rear wheels are raised.
Proper towing equipment is necessary to prevent dam-
age to the vehicle.
Battery power is required to release the brake/
transmission interlock system. There is a removable plug
in the right side of the shifter housing that allows you to
insert your finger to override the system. The ignition
key must be in the on position to use the override lever.
Towing This Vehicle Behind Another Vehicle (Flat
Towing With All Four Wheels On The Ground)
CAUTION!
DO NOT flat tow this vehicle. Damage to the driv-
etrain will result.
