2013 JEEP GRAND CHEROKEE brake

NOTE:
Press theESC Offswitch (if necessary), to
place the Electronic Stability Control (ESC)
system in Partial Off mode, before rocking
the vehicle. Refer to “Electronic Brake Con-
trol” in “Starting And Operating” for further
information. Once the vehicle has been
freed, press the ESC Offswitch again to
restore ESC On mode.
CAUTION!
Racing the engine or spinning the wheels
may lead to transmission overheating and
failure. Allow the engine to idle with the
transmission in NEUTRAL for at least one
minute after every five rocking-motion
cycles. This will minimize overheating and
reduce the risk of transmission failure during
prolonged efforts to free a stuck vehicle.
CAUTION!
•
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or
drivetrain damage may result.
•Revving the engine or spinning the wheels
too fast may lead to transmission over-
heating and failure. It can also damage the
tires. Do not spin the wheels above
30 mph (48 km/h) while in gear (no trans-
mission shifting occurring).
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s
(Continued)
WARNING!(Continued)
wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without
stopping when you are stuck and do not let
anyone near a spinning wheel, no matter
what the speed.
TOW EYES
Your vehicle is equipped with tow eyes, which
are mounted in the front and the rear.
CAUTION!
Tow eyes are for emergency use only, to
rescue a vehicle stranded off road. Do not use
tow eyes for tow truck hookup or highway
towing. You could damage your vehicle. Tow
straps are recommended when towing the
vehicle; chains may cause vehicle damage.
303

WARNING!
Stand clear of vehicles when pulling with tow
eyes. Tow straps and chains may break,
causing serious injury.
SHIFT LEVER OVERRIDE
If a malfunction occurs and the shift lever can-
not be moved out of the PARK position, you can
use the following procedure to temporarily
move the shift lever:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
3. Remove the rubber liner from the cupholder
(located next to the shifter on the center con-
sole).
4. Using a small screwdriver or similar tool,
remove the shift lever override access cover
(located on the bottom of the cupholder).5. Press and maintain firm pressure on the
brake pedal.
6. Insert the screwdriver or similar tool into the
access hole, and push and hold the override
release lever down.
7. Move the shift lever to the NEUTRAL posi-
tion.
8. The vehicle may then be started in NEU-
TRAL.
9. Reinstall the shift lever override access
cover and cupholder liner.
TOWING A DISABLED
VEHICLE
This section describes procedures for towing a
disabled vehicle using a commercial wrecker
service. If the transmission and drivetrain are
operable, disabled vehicles may also be towed
as described under “Recreational Towing” in the
“Starting And Operating” section.
NOTE:
Vehicles equipped with Quadra-Lift™ must
be lowered to the Park (lowest) level, and
have automatic leveling disabled, before ty-
ing them down (from the body) on a trailer or
flatbed truck. Refer to the section on
Quadra-Lift™ for more information. If the
vehicle cannot be lowered to the Park level
(for example, engine will not run), tie-downs
must be fastened to the axles (not to the
body). Failure to follow these instructions
may cause fault codes to be set and/or
cause loss of proper tie-down tension.

Points To Remember
NOTE:
When the vehicle is stopped after a few
miles/kilometers of operation, you may ob-
serve vapor coming from the front of the
engine compartment. This is normally a re-
sult of moisture from rain, snow, or high
humidity accumulating on the radiator and
being vaporized when the thermostat opens,
allowing hot engine coolant (antifreeze) to
enter the radiator.
If an examination of your engine compartment
shows no evidence of radiator or hose leaks,
the vehicle may be safely driven. The vapor will
soon dissipate.
•Do not overfill the coolant expansion bottle.
• Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant (antifreeze) needs to be added, the
contents of the coolant expansion bottle must
also be protected against freezing.
• If frequent engine coolant (antifreeze) addi-
tions are required, the cooling system should
be pressure tested for leaks. •
Maintain engine coolant (antifreeze) concen-
tration at a minimum of 50% OAT coolant
(conforming to MS-12106) and distilled water
for proper corrosion protection of your engine
which contains aluminum components.
• Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
•
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces-
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine coolant (antifreeze) performance, poor
gas mileage, and increased emissions.
Brake SystemIn order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the “Maintenance
Schedule” for the proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal can
result in abnormally high brake tempera-
tures, excessive lining wear, and possible
brake damage. You would not have your full
braking capacity in an emergency.
Fluid Level Check – Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood ser-
vice, or immediately if the brake system warning
lamp indicates system failure.
The brake master cylinder has a plastic reser-
voir. On the outboard side of the reservoir, there
is a “MAX” dot and a “MIN” dot. The fluid level
must be kept within these two dots. Do not add
fluid above the MAX mark, because leakage
may occur at the cap.
324

With disc brakes, the fluid level can be expected
to fall as the brake linings wear. However, an
unexpected drop in fluid level may be caused by
a leak and a system check should be con-
ducted.
Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for further informa-
tion.
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 mas-
ter cylinder 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 se-
cured at all times. Brake fluid in a open
container absorbs moisture from the air re-
sulting 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.
• Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This
could result in a collision.
Front/Rear Axle FluidFor normal service, periodic fluid level checks
are not required. When the vehicle is serviced
for other reasons the exterior surfaces of the
axle assembly should be inspected. If gear oil
leakage is suspected inspect the fluid level.
Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for further informa-
tion.
Front Axle Fluid Level Check
The front axle oil level needs to be between 1/8
in (3 mm) below the bottom of the fill hole and
the bottom of the fill hole.
The front axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not over tighten the plugs as it could
damage them and cause them to leak.
Rear Axle Fluid Level Check
The rear axle oil level needs to be between 1/8
in (3 mm) below the bottom of the fill hole and
the bottom of the fill hole. 325
