2012 JEEP COMPASS ECU

For vehicles equipped with plastic trim, the plastic has
been cut away to expose the jacking locations in the body.
Do not raise the vehicle until you are sure the jack is
securely engaged.3. Turn the jack screw to the left until the jack can be
placed under the jacking location. Once the jack is
positioned, turn the jack screw to the right until the jack
head is properly engaged with the lift area closest to the
wheel to be changed.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
4. Using the swivel wrench raise the vehicle by turning
the jack screw to the right. Raise the vehicle only until the
tire just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire lift
provides maximum stability.

WHAT TO DO IN EMERGENCIES 387

NOTE:The wheel cover is held on the wheel by the
wheel nuts. When reinstalling the original wheel, prop-
erly align the wheel cover to the valve stem, place the
wheel cover onto the wheel, then install the wheel nuts.
6. Lower the vehicle by turning the jack screw to the left.
7. Finish tightening the nuts. Push down on the wrench
while at the end of the handle for increased leverage.
Tighten the lug nuts in a star pattern until each nut has
been tightened twice. The correct wheel nut torque is
100 ft lbs (135 N·m). If you doubt that you have tightened
the nuts correctly, have them checked with a torque
wrench by your authorized dealer or service station.
8. Remove the wheel blocks and lower the jack until it is
free. Reassemble the lug wrench to the jack assembly and
stow it in the spare tire area. Secure the assembly using
the means provided.WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
9. Place the deflated (flat) tire in the cargo area, have the
tire repaired or replaced as soon as possible.
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.
10. Check the spare tire pressure as soon as possible.
Correct the tire pressure as required.6
WHAT TO DO IN EMERGENCIES 389

•FWD vehicles can be towed with the front wheels
elevated.
•FWD or 4WD vehicles can be towed on a flatbed truck
(all wheelsOFFthe ground).
CAUTION!
DO NOT flat tow disabled vehicle if condition is
related to the clutch, transmission or driveline.
Additional damage to the drivetrain could result.
All Transmissions
If you must use the accessories (wipers, defroster, etc.)
while being towed (wipers, defrosters, etc.), the key must
be in the ON/RUN position, not the ACC position. Make
certain the transmission remains in NEUTRAL.
If the vehicle’s battery is discharged, see “Shift Lever
Override” in “What To Do In Emergencies” for instruc-
tions on shifting the automatic transmission out of the
PARK position for towing.
CAUTION!
Failure to follow these cautions could result in dam-
age to your vehicle:
•Do not attempt to use sling-type equipment when
towing. When securing the vehicle to a flatbed
truck, do not attach to front or rear suspension
components.
•If the vehicle being towed requires steering, the
ignition switch must be in the ON/RUN or ACC
position, not in the LOCK/OFF position.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK/OFF position. The only
approved method of towing without the ignition key is
with a flatbed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.

416 MAINTAINING YOUR VEHICLE

WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also identified on the
original factory installed hydraulic master cylin-
der reservoir.(Continued)
WARNING! (Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep the
master cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly during hard
or prolonged braking, resulting in sudden brake
failure. This could result in a collision.
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.(Continued)
