FREEING A STUCK VEHICLE

If your vehicle becomes stuck in mud, sand or snow,
it can often be moved using a rocking motion. Turn
the steering wheel right and left to clear the area
around the front wheels. For vehicles with
automatic transmission, push and hold the lock
button on the gear selector. Then, shift back and
forth between DRIVE (D) and REVERSE (R) (with
automatic transmission) or SECOND (2) gear and
REVERSE (R) (with manual transmission), while
gently pressing the accelerator. Use the least
amount of accelerator pedal pressure that will
maintain the rocking motion, without spinning the
wheels or racing the engine.

NOTE:
For vehicles with automatic transmission: Shifts
between DRIVE (D) and REVERSE (R) can only
be achieved at wheel speeds of 5 mph (8 km/h)
or less. Whenever the transmission remains in
NEUTRAL(N) for more than 2 seconds, you must
press the brake pedal to engage DRIVE (D) or
REVERSE (R).
Push the ESC OFF button to place the Electronic
Stability Control (ESC) system in “Partial OFF”
mode, before rocking the vehicle Ú page 281.

IN CASE OF EMERGENCY351
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow bars
and other equipment designed for this purpose,
following equipment manufacturer’s instructions.
Use of safety chains is mandatory. Attach a tow bar
or other towing device to main structural members
of the vehicle, not to fascia/bumpers or associated
brackets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN position, not the ACC
position.
If the vehicle's battery is discharged, instructions
on shifting the automatic transmission out of
PARK (P) in order to move the vehicle Úpage 348.
FOUR–WHEEL DRIVE MODELS
FCA LLC US recommends towing with all wheels
OFF the ground. Acceptable methods are to tow
the vehicle on a flatbed or with one end of the
vehicle raised and the opposite end on a towing
dolly.
If flatbed equipment is not available and the
transfer case is operable, the vehicle may be
towed (in the forward direction, with ALL wheels on
the ground), IF the transfer case is in NEUTRAL (N)
and the transmission is in PARK (P) (for automatic
transmissions) or in gear ( NOT in NEUTRAL , for
manual transmissions) Ú page 205.
WITHOUT THE KEY FOB
Special care must be taken when the vehicle is
towed with the ignition in the OFF position. The only
approved method of towing without the key fob is
with a flatbed truck. Proper towing equipment is
necessary to prevent damage to the vehicle.
EMERGENCY TOW HOOKS —
I

BODY LUBRICATION
Locks and all body pivot points, including such
items as seat tracks, door hinge pivot points and
rollers, liftgate, tailgate, decklid, sliding doors, and
hood hinges should be lubricated periodically with
a lithium-based grease, such as Mopar® Spray
White Lube, to ensure quiet, easy operation and to
protect against rust and wear. Prior to the application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit.
After lubricating, excess oil and grease should be
removed. Particular attention should also be given
to hood latching components to ensure proper
function. When performing other underhood
services, the hood latch, release mechanism and
safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated
twice a year, preferably in the Autumn and Spring.
Apply a small amount of a high quality lubricant,
such as Mopar® Lock Cylinder Lubricant, directly
into the lock cylinder.
WINDSHIELD WIPER BLADES
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove
accumulations of salt or road film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using the
wipers to remove salt or dirt from a dry windshield.
Avoid using the wiper blades to remove frost or ice
from the windshield. Keep the blade rubber out of
contact with petroleum products such as engine
oil, gasoline, etc.
CAUTION!
The cabin air filter is identified with an arrow to
indicate airflow direction through the filter.
Failure to properly install the filter will result in
the need to replace it more often.

BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically. For the proper maintenance intervals
Úpage 354.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked whenever the vehicle is serviced, or
immediately if the Brake System Warning Light is
on. If necessary, add fluid to bring level within the
designated marks on the side of the reservoir of
the brake master cylinder. Be sure to clean the top
of the master cylinder area before removing cap.
With disc brakes, fluid level can be expected to fall
as the brake pads wear. Brake fluid level should be
checked when pads are replaced. If the brake fluid
is abnormally low, check the system for leaks.
For further information Ú page 426.
FRONT/REAR AXLE FLUID
For 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.
Fluid Level Check
Lubricant should be approximately 1/8 inch
(3 mm) below the bottom edge of the oil fill hole.
NOTE:Make sure that the vehicle is level and supported
by the axles.
Adding Fluid
Add lubricant only at the fill hole and only to the
level specified above.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid
Úpage 426.
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 temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.
WARNING!
Use only manufacturer recommended brake
fluid Ú page 426. 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 cylinder reservoir.
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.
Do not allow petroleum based fluid to contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.

When washing, never use hot water or anything
stronger than a mild soap. Never use solvents
such as alcohol or harsh cleaning agents.
Always rinse thoroughly with cold water, then
wipe with a soft and slightly moist, clean cloth.
When removing frost, snow, or ice, never use a
scraper or de-icing chemicals. Use warm water
only if you must clean the window quickly.
Debris (sand, mud/dirt, dust, or salt) from
off-road driving will have an impact on plastic
retainer operation. Even normal on-road driving
and vehicle washing will eventually impact
window plastic retainer operation. To maintain
ease of use of the window plastic retainers,
each window plastic retainer should be cleaned
and lubricated regularly. Clean them with a mild
soap solution and a small brush. Cleaning prod -
ucts are available through an authorized dealer.
Never paste stickers, gummed labels or any
tape to the windows. Adhesives are hard to
remove and may damage the windows.
INTERIORS
CARPET SAFETY INFORMATION
Always use carpet designed to fit your vehicle. Only
use carpet that does not interfere with the
operation of the pedal assemblies. Only operate
the vehicle when the carpet is securely attached by
the grommets so it cannot slip out of position and
interfere with the pedal assemblies or impair safe
operation of your vehicle in other ways.
WARNING!
If operating the vehicle without carpet in place
the floor may become hot, and there is a risk
of burns.
An improperly attached, damaged, folded, or
damaged grommets may cause your carpet to
interfere with the accelerator, brake, or clutch
pedals and cause a loss of vehicle control. To
prevent SERIOUS INJURY or DEATH: ALWAYS
securely attach your carpet using the grom -
mets.
ALWAYS make sure objects cannot fall or slide
into the driver’s side floor area when the
vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
NEVER place any objects under the carpet
(e.g., towels, keys, etc.). These objects could
change the position of the carpet and may
cause interference with the accelerator,
brake, or clutch pedals.
ONLY install carpet designed to fit your
vehicle. NEVER install carpet that cannot be
properly attached and secured to your vehicle.
If the carpet needs to be replaced, only use
manufacturer approved carpet for the specific
make, model, and year of your vehicle.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check that the floor mat
fasteners are secure to the vehicle carpet.
