366IN CASE OF EMERGENCY
MANUAL PARK RELEASE — 8 – SPEED
TRANSMISSION
To push or tow the vehicle in cases where the
transmission will not shift out of PARK (such as
a depleted battery), a Manual Park Release is
available.
Manual Park Release Panel Cover
Manual Park Release Pull Strap

Follow these steps to activate the Manual Park
Release:

1. Firmly apply the parking brake.
2. Using a small screwdriver or similar tool,
remove the Manual Park Release access
cover, which is just above the parking brake
release handle, below and to the left of the
steering column.
3. Press and maintain firm pressure on the brake pedal.
4. Using the screwdriver or similar tool, push the Manual Park Release lever locking tab
(just below the middle of the lever) to the
right.
5. While holding the locking tab in the disen -
gaged position, pull the tether strap to
rotate the lever rearward, until it locks in
place pointing towards the driver's seat.
Release the locking tab and verify that the
Manual Park Release lever is locked in the
released position.
6. The vehicle is now out of PARK and can be towed. Release the parking brake only when
the vehicle is securely connected to a tow
vehicle.
WARNING!
Always secure your vehicle by fully applying
the parking brake before activating the
Manual Park Release. In addition, you should
be seated in the driver’s seat with your foot
firmly on the brake pedal when activating the
Manual Park Release. Activating the Manual
Park Release will allow your vehicle to roll
away if it is not secured by the parking brake,
or by proper connection to a tow vehicle.
Activating the Manual Park Release on an
unsecured vehicle could lead to serious injury
or death for those in or around the vehicle.

370IN CASE OF EMERGENCY
If the key fob is unavailable or the vehicle's
battery is discharged, refer to ”Manual Park
Release” in this section for instructions on
shifting the transmission out of PARK for
towing.
Two-Wheel Drive Models
The manufacturer recommends towing your
vehicle with all four wheels OFF the ground
using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be
towed (with rear wheels ON the ground) under
the following conditions:
The transmission must be in NEUTRAL. NOTE:
Refer to “Manual Park Release” in this section
for instructions on shifting the transmission to
NEUTRAL when the engine is OFF.
The towing speed must not exceed 30 mph
(48 km/h).
The towing distance must not exceed
30 miles (48 km) for 8–speed transmission.
The towing distance must not exceed
15 miles (24 km) for 6–speed transmission.
If the transmission is not operable, or the
vehicle must be towed faster than 30 mph
(48 km/h) or farther than 30 miles (48 km) for 8–speed transmission, tow with the rear wheels
OFF the ground. Acceptable methods are to tow
the vehicle on a flatbed, or with the front wheels
raised and the rear wheels on a towing dolly, or
(when using a suitable steering wheel stabilizer
to hold the front wheels in the straight position)
with the rear wheels raised and the front wheels
on the ground.
Four-Wheel Drive Models
The manufacturer recommends towing with all
wheels OFF the ground. Acceptable methods
are to tow the vehicle on a flatbed or with one
end of 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.
Refer to “Recreational Towing” in “Starting And
Operating” for further information and detailed
instructions.
CAUTION!
Do not use sling type equipment when
towing. Vehicle damage may occur.
When securing the vehicle to a flat bed
truck, do not attach to front or rear suspen -
sion components. Damage to your vehicle
may result from improper towing.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe transmission
damage. Damage from improper towing is not
covered under the New Vehicle Limited
Warranty.

After the engine has warmed up, operate the
defroster for a few minutes to reduce the possi -
bility of smearing or freezing the fluid on the
cold windshield. Windshield washer solution
used with water as directed on the container,
aids cleaning action, reduces the freezing point
to avoid line clogging, and is not harmful to
paint or trim.
Maintenance-Free Battery
Your vehicle is equipped with a mainte-
nance-free battery. You will never have to add
water, nor is periodic maintenance required.
Pressure Washing
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water. Refer to “Jump
Starting Procedure” in “In Case Of Emer -
gency” for further information.
Battery gas is flammable and explosive.
Keep flame or sparks away from the
battery. Do not use a booster battery or any
other booster source with an output greater
than 12 Volts. Do not allow cable clamps to
touch each other.
Battery posts, terminals, and related acces -
sories contain lead and lead compounds.
Wash hands after handling.
CAUTION!
It is essential when replacing the cables on
the battery that the positive cable is
attached to the positive post and the nega -
tive cable is attached to the negative post.
Battery posts are marked positive (+) and
negative (-) and are identified on the battery
case. Cable clamps should be tight on the
terminal posts and free of corrosion.
If a “fast charger” is used while the battery
is in the vehicle, disconnect both vehicle
battery cables before connecting the
charger to the battery. Do not use a “fast
charger” to provide starting voltage.
CAUTION!
Cleaning the engine compartment with a high
pressure washer is not recommended.
Precautions have been taken to safeguard all
parts and connections however, the
pressures generated by these machines is
such that complete protection against water
ingress cannot be guaranteed.

Standard No. 109. Grades B and A repre -
sent higher levels of performance on the
laboratory test wheel, than the minimum
required by law.
STORING THE VEHICLE
If you are storing your vehicle for more than
21 days, we recommend that you take the
following steps to minimize the drain on your
vehicle's battery:
Disconnect the negative cable from battery.
Any time you store your vehicle or keep it out
of service (i.e., vacation) for two weeks or
more, run the air conditioning system at idle
for about five minutes in the fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according
to geographic locations and usage. Chemicals
that make roads passable in snow and ice and
those that are sprayed on trees and road
surfaces during other seasons are highly corro
-
sive to the metal in your vehicle. Outside
parking, which exposes your vehicle to airborne
contaminants, road surfaces on which the
vehicle is operated, extreme hot or cold weather
and other extreme conditions will have an
adverse effect on paint, metal trim, and under -
body protection.
The following maintenance recommendations
will enable you to obtain maximum benefit from
the corrosion resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or
removal of paint and protective coatings from
your vehicle. The most common causes are:
Road salt, dirt and moisture accumulation.
Stone and gravel impact.
Insects, tree sap and tar.
Salt in the air near seacoast localities.
Atmospheric fallout/industrial pollutants.
Body And Underbody Maintenance
Cleaning Headlights
Your vehicle is equipped with plastic headlights
and fog lights that are lighter and less suscep
-
tible to stone breakage than glass headlights.
Plastic is not as scratch resistant as glass and
therefore different lens cleaning procedures
must be followed.
To minimize the possibility of scratching the
lenses and reducing light output, avoid wiping
with a dry cloth. To remove road dirt, wash with
a mild soap solution followed by rinsing.
Do not use abrasive cleaning components,
solvents, steel wool or other aggressive mate -
rial to clean the lenses.
WARNING!
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.
