systems of your vehicle, particularly the igni-
tion and engine fuel supply control units.
1. Apply the parking brake, shift the auto -
matic transmission into PARK and turn
the ignition OFF.
2. Turn off the heater, radio, and all unnec -
essary electrical accessories.
3. If using another vehicle to jump start the battery, park the vehicle within the
jumper cable’s reach, apply the parking
brake and make sure the ignition is OFF.Jump Starting Procedure
NOTE:
Make sure at all times that unused ends of
jumper cables are not contacting each other
or either vehicle while making connections. Connecting The Jumper Cables
Jumper Cable Connections
1. Connect the positive (+) end of the
jumper cable to the remote positive (+)
post of the discharged vehicle.
2. Connect the opposite end of the positive (+) jumper cable to the positive (+) post
of the booster battery.
3. Connect the negative end (-) of the
jumper cable to the negative (-) post of
the booster battery.
WARNING!
Do not allow vehicles to touch each other
as this could establish a ground
connection and personal injury could
result.
WARNING!
Failure to follow this jump starting
procedure could result in personal injury or
property damage due to battery explosion.
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of
the booster vehicle or the discharged
vehicle.

IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by
taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, shift trans-
mission into NEUTRAL (N), but do not
increase engine idle speed.NOTE:
There are steps that you can take to slow
down an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it
off. The A/C system adds heat to the
engine cooling system and turning the A/C
off can help remove this heat.
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 supple-
ment to the radiator and aids in removing
heat from the engine cooling system.
MANUAL PARK RELEASE
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.
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.
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.

205
To push or tow the vehicle in cases where the
transmission will not shift out of PARK (P)
(such as a depleted battery), a Manual Park
Release is available.
Follow these steps to use the Manual Park
Release:
1. Firmly apply the parking brake.
2. Using a small screwdriver, or similar tool,remove the manual park release cover,
located above the gear selector, to access
the release tether strap.
Manual Park Release Cover 3. Fish the tether strap up through the
opening in the console base.
Tether Strap
4. Press and maintain firm pressure on the brake pedal.
5. Pull the tether strap up and to the left until the release lever locks into place in
the vertical position. The vehicle is now
out of PARK and can be moved. Release
the parking brake only when the vehicle
is securely connected to a tow vehicle. To Reset The Manual Park Release:
1. Pull upward on the tether strap, releasing
it from the “locked” position.
2. Lower the Manual Park Release lever downward and to the right, into its orig -
inal position.
3. Tuck the tether strap into the base of the console, and reinstall the cover.

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 trans-
mission, push and hold the lock button on
the gear selector. Then, shift back and forth
between DRIVE (D) and REVERSE (R), 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 and REVERSE 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 two seconds, you must press
the brake pedal to engage DRIVE or
REVERSE.
Push the “ESC OFF” switch, to place the
Electronic Stability Control (ESC) system
in “Partial Off” mode, before rocking the
vehicle. Refer to “Electronic Brake Control
System” in “Safety” in your Owner’s Manual for further details. Once the
vehicle has been freed, push the “ESC
OFF” switch again to restore “ESC On”
mode.
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 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.
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 mini
-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
When “rocking” a stuck vehicle by
shifting between DRIVE/SECOND GEAR
and REVERSE, do not spin the wheels
faster than 15 mph (24 km/h), or drive -
train damage may result.
Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also
damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
CAUTION! (Continued)
