Lumbar Support
This feature allows you to increase or decrease the
amount of lumbar support. Turn the control lever for-
ward to increase and rearward to decrease the desired
amount of lumbar support.
Heated Seats—If Equipped
Heated seats, which are available only with leather
upholstery, provide comfort and warmth on cold days
and can help soothe sore muscles and backs. The heaters
provide the same heat level for both cushion and back.The front driver’s and passenger seats are heated. The
controls for each heater are located near the bottom
center of the instrument panel. After turning on the
ignition, you can choose from High, Off, or Low heat
settings. Amber LEDs in the top portion of each switch
indicate the level of heat in use. Two LEDs are illumi-
nated for high, one for low, and none for off. Pressing the
switch once will select high-level heating.

Pressing the switch a second time will select low-level
heating. Pressing the switch a third time will shut the
heating elements off.
When high-temperature heating is selected, the heaters
provide a boosted heat level during the first four minutes
of operation after heating is activated. The heat output
then drops to the normal high-temperature level. If
high-level heating is selected, the system will automati-
cally switch to the low level after two hours of continu-
ous operation. At that time, the number of illuminated
LEDs changes from two to one, indicating the change.
Operation on the low setting also turns off automatically
after two hours.
NOTE:Once a heat setting is selected, heat will be felt
within two to five minutes.
WARNING!
Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns even
at low temperatures, especially if used for long
periods of time.
Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This may
cause the seat heater to overheat.

STARTING PROCEDURES
CAUTION!
Long periods of engine idling, especially at high
engine speeds, can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
WARNING!
Do not leave animals or children inside parked
vehicles in hot weather; interior heat build up may
cause serious injury or death.
The gear selector must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
Normal Starting
Normal Startingof either a cold or a warm engine is
obtained without pumping or depressing the accelerator
pedal. Turn the key to the“START”position and release
when the engine starts. If the engine has not started
within 3 seconds, slightly depress the accelerator pedal
while continuing to crank. If the engine fails to start
within 15 seconds, turn the key to the“OFF”position,
wait 10 to 15 seconds, then repeat the normal starting
procedure.
Extremely Cold Weather(below20°For29°C) To
insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
202 STARTING AND OPERATING
Page 204 of 376
After Starting
The idle speed will automatically decrease as the engine
warms up.
ENGINE BLOCK HEATER—IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater cord is routed under the hood on
the driver side of the vehicle. It has a removable cap that
is located on the driver side of the Integrated Power
Module.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could
cause electrocution.
TRANSMISSION SHIFTING
4 Speed Automatic Transmission
Shifting from D (Drive) to P (Park) or R (Reverse) (or
from P or R to D) should be done only after the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake when moving the
shift lever between these gears.

removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
the fan control to HI. This allows the heater core to act as
a supplement to the radiator and aids in removing heat
from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads“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
the“H”, turn the engine off immediately, and call for
service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
JACKING AND TIRE CHANGING
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.

WARNING!
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the engine
has started, ignite and damage the converter and
vehicle. If the vehicle has a discharged battery, booster
cables may be used to obtain a start from another
vehicle. This type of start can be dangerous if done
improperly, so follow this procedure carefully.
•Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or clothing.
Don’t lean over battery when attaching clamps or
allow the clamps to touch each other. If acid splashes
in eyes or on skin, flush contaminated area immedi-
ately with large quantities of water.
•A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away from
the vent holes. Do not use a booster battery or any
other booster source with an output that exceeds 12
volts.
•The battery in this vehicle has a vent hose that
should not be disconnected and should only be
replaced with a battery of the same type (vented).
NOTE:The battery is stored under an access cover
under the rear cargo floor. Remote battery terminals are
located in the engine compartment for jump starting.
1. Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
inadvertent electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach and
without letting the vehicles touch. Set the parking brake,
place the automatic transmission in PARK and turn the
ignition switch to the OFF (or LOCK) position for both
vehicles.
3. Turn off the heater, radio and all unnecessary electrical
loads.
4. Connect one end of the jumper cable to the remote
jump start positive battery post (A) in the engine com-
partment. Connect the other end of the same cable to the
positive terminal of the booster battery. Refer to the
following illustration for jump starting connections.
5. Connect the other cable, first to the negative terminal
of the booster battery andthen to the engine ground (B)
