driving position when the key is placed into the
ignition, and turned out of the LOCK position toward
the ACC/ON position.
The Easy Entry/Exit feature will be automatically dis-
abled if the seat is already positioned closer than 0.9 in
(23 mm) forward of the rear stop. At this position, there
is no benefit to the driver by moving the seat for Easy
Exit/Entry.
Each stored memory setting will have an associated Easy
Entry/Exit position.
NOTE:The Easy Entry/Exit feature is not enabled
when the vehicle is delivered from the factory. The Easy
Entry/Exit feature is enabled (or later disabled) through
the programmable features in the Electronic Vehicle
Information Center (EVIC). Refer to “Electronic Vehicle
Information Center (EVIC)/Customer-Programmable
Features” in “Understanding Your Instrument Panel” for
further information.TO OPEN AND CLOSE THE HOOD

2. Reach under the hood, move safety latch to the left
and lift the hood.CAUTION!
To prevent possible damage, do not slam the hood to
close it. Use a firm downward push at the center of
the hood to ensure that both latches engage.

Be sure the hood is fully latched before driving your
vehicle. If the hood is not fully latched, it could open
when the vehicle is in motion and block your vision.
Failure to follow this warning could result in serious
injury or death.

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.
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.
JACKING AND TIRE CHANGING
Run Flat Tires
This vehicle is equipped with run flat tires. Although the
tires are designed with a “run flat” feature that allows the
vehicle to be driven approximately 50 miles (80 km) at
55 mph (88 km/h). immediate service should be ob-
tained.6
WHAT TO DO IN EMERGENCIES 461

WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is on. You can be injured by
moving fan blades.
•Remove any metal jewelry such as watch bands or
bracelets that might make an inadvertent electrical
contact. You could be seriously injured.
•Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, shift the automatic transmission
into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories.

WHAT TO DO IN EMERGENCIES 463

Cooling System
WARNING!
•When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition
switch to the OFF position. The fan is temperature
controlled and can start at any time the ignition
switch is in the ON position.
•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 is hot.
Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty orrusty in appearance, the system should be drained,
flushed and refilled with fresh coolant. Check the front of
the A/C condenser for any accumulation of bugs, leaves,
etc. If dirty, clean by gently spraying water from a garden
hose vertically down the face of the condenser.
Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
engine coolant (antifreeze) from the radiator drain cock.
If the cap is sealing properly, the engine coolant (anti-
freeze) will begin to drain from the coolant recovery
bottle. DO NOT REMOVE THE COOLANT PRESSURE
CAP WHEN THE COOLING SYSTEM IS HOT.

BULB REPLACEMENT
High Intensity Discharge Headlamps (HID) – If
Equipped
The headlamps are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlamp switch off and the key removed.Because of
this, you should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high voltage occurs at the bulb sockets of
High Intensity Discharge (HID) headlamps when the
headlamp switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.NOTE:On vehicles equipped with High Intensity Dis-
charge (HID) headlamps, when the headlamps are
turned on, there is a blue hue to the lamps. This dimin-
ishes and becomes more white after approximately
10 seconds, as the system charges.
Halogen Headlamps – If Equipped
1. Open the hood.
2. Turn the low or high beam bulb one–quarter turn
counterclockwise to remove from housing.
3. Disconnect the electrical connector and replace the
bulb.

CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.
Front Turn Signal
1. Open the hood.
2. Turn the turn signal bulb one–quarter turn counter-
clockwise to remove from housing.
3. Disconnect the electrical connector and replace the
bulb.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.
Front Fog Lamps
1. Reach through the cutout in the splash shield and
disconnect the wiring harness from the fog lamp connec-
tor.
2. Firmly grasp the bulb by the two latches and squeeze
them together to unlock the bulb from the back of the
front fog lamp housing.
3. Pull the bulb straight out from the keyed opening in
the housing.
