JUMP STARTING
If your vehicle has a discharged battery, it can be jump
started using a set of jumper cables and a battery in another
vehicle, or by using a portable battery booster pack. Jump
starting can be dangerous if done improperly, so please
follow the procedures in this section carefully.
WARNING!
Do not attempt jump starting if the battery is frozen. It
could rupture or explode and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any other
booster source with a system voltage greater than 12
Volts or damage to the battery, starter motor, alternator
or electrical system may occur.
NOTE: When using a portable battery booster pack, follow
the manufacturer’s operating instructions and precautions.Jack Hold Down Wing Bolt

•You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on HOT
(H), and you hear continuous chimes, turn the engine
off immediately and call for service.
MANUAL PARK RELEASE
WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park Re-
lease. 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.
In order to push or tow the vehicle in cases where the
transmission will not shift out of PARK (such as a dead
battery), a Manual Park Release is available.
Follow these steps to activate the Manual Park Release:
1. Apply the parking brake.

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 disengaged posi-
tion, 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.
To Reset The Manual Park Release:
1. Push the locking tab to the right, to unlock the lever.
2. Rotate the Manual Park Release lever forward to its original position, until the locking tab snaps into place
to secure the lever.
3. Pull gently on the tether strap to confirm that the lever is locked in its stowed position.
4. Re-install the access cover.

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 suspension components. Dam-
age to your vehicle may result from improper towing.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheels OFFthe 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).
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), tow with the rear wheels
OFFthe 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.
CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe transmission damage. Damage
from improper towing is not covered under the New
Vehicle Limited Warranty.
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 ALLwheels on the ground), IFthe transfer
case is in NEUTRAL (N) and the transmission is in PARK.

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly 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.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service or immediately if
the brake system warning lamp indicates system failure.
The brake master cylinder has a translucent plastic reser-
voir. On the outboard side of the reservoir, there is a
“MAX” mark and a “MIN” mark. The fluid level must be
kept within these two marks. Do not add fluid above the
MAX mark because leakage may occur at the cap.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 conducted.
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
WARNING!
•
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” 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 cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der 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
