even when the doors and liftgate are open. While in the
ªOffº position the instrument panel lighting is at the
lowest light level and may not be suitable for night
driving.
Daytime Running Lights Ð If Equipped
The high beam headlights come on at a low intensity
level whenever the engine is running, and the transmis-
sion in not in the P (Park) position. The lights remain on
until the ignition switch is turned OFF or the parking
brake is engaged. The headlight switch must be used for
normal night time driving.
Automatic Headlight Leveling Ð HID Headlights
Only
This feature prevents the headlights from interfering
with the vision of oncoming drivers. Headlight leveling
automatically adjusts the height of the headlight beam in
reaction to changes in vehicle pitch.
Lights-On Reminder
If the headlights or parking lights are on after the ignition
is turned OFF, a chime will sound when the driver's door
is opened.
Fog Lights Ð If Equipped
The fog light switch is located in the multi-
function control lever. To activate the fog lights,
turn on the park/turn lights, low beam headlights,
or ªAutoº headlights and pull out the end of the multi-
function control lever. A light in the instrument cluster
shows when the fog lights are on.
NOTE:Turning on the high beam headlights turns off
the fog lights.
A front fog light is a lighting device providing illumina-
tion forward of the vehicle under conditions of fog, rain,
snow, or dust. Principally, the front fog light supplements
the lower beam of a standard headlight system.

²Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in R (Reverse) gear).
HSA will work in R (Reverse) and all forward gears when
the activation criteria have been met. The system will not
activate if the vehicle is placed in N (Neutral) or P (Park).
WARNING!
There may be situations on minor hills (i.e., less than
8%), with a loaded vehicle, or while pulling a trailer,
when the system will not activate and slight rolling
may occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
Towing with HSA
HSA will provide assistance when starting on a grade
when pulling a trailer.
WARNING!
²If you use a trailer brake controller with your
trailer, your trailer brakes may be activated and
deactivated with the brake switch. If so, when the
brake pedal is released there may not be enough
brake pressure to hold the vehicle and trailer on a
hill and this could cause a collision with another
vehicle or object behind you. In order to avoid
rolling down the hill while resuming accelera-
tion, manually activate the trailer brake prior to
releasing the brake pedal. Always remember the
driver is responsible for braking the vehicle.
²HSA is not a parking brake. If you stop the
vehicle on a hill without putting the transmission
in P (Park) and using the parking brake, it will
roll down the hill and could cause a collision with
another vehicle or object. Always remember to
use the parking brake while parking on a hill,
and that the driver is responsible for braking the
vehicle.

INSTRUMENT CLUSTER DESCRIPTION
1. Speedometer
Indicates vehicle speed.
2. Brake Warning Light
The BRAKE warning light will come on when
the ignition is first turned on, and stay on
briefly as a bulb check. If the bulb does not
come on during starting, have the bulb re-
paired promptly. If the light stays on longer, it may be an
indication that the parking brake has not been released.
If the light remains on when the parking brake is off, it
indicates a possible brake hydraulic system malfunction
or low fluid level. In this case, the light will remain on
until the cause is corrected. If a brake malfunction is
indicated, immediate repair is necessary and continued
operation of the vehicle in this condition is dangerous.3. Turn Signal Indicator Light
The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
If the vehicle electronics sense that the vehicle has
traveled about one mile with the turn signals on, a chime
will sound to alert you to turn the signals off. If either
indicator flashes at a rapid rate, check for a defective
outside light bulb.
4. High Beam Indicator Light
Indicates that headlights are on high beam.
5. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD II that monitors engine and auto-
matic transmission control systems. The light will
illuminate when the key is in the ON position

272 STARTING AND OPERATING

1. Firmly set the parking brake.
2. Using a flat blade screwdriver, carefully remove the
shift lock manual override cover which is located on the
PRNDL bezel.
3.
Depress and maintain firm pressure on the brake pedal.
4. Using the screwdriver, reach into the manual override
opening. Press and hold the shift lock lever down.5. Move the shift lever into the N (Neutral) position.
6. The vehicle may then be started in N (Neutral).
Have your vehicle inspected by your local authorized
dealer, if the shift lock manual override has been used.Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of P (Park) and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position. Always depress thebrake
pedal first,before moving the gear selector out of P
(Park).
5±Speed Automatic Transmission
The electronically controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
STARTING AND OPERATING 285

vehicle, may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles.
Gear Ranges
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold. If
there is a need to restart the engine be sure to cycle the
key to the LOCK position before restarting. Transmission
gear engagement may be delayed after restarting the
engine if the key is not cycled to the LOCK position first.
P (Park)
This gear position supplements the parking brake by
locking the transmission. The engine can be started in
this range. Never use P (Park) while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range. Always apply parking brake first,
then place the selector in P (Park) position.
WARNING!
Never use P (Park) position as a substitute for the
parking brake. Always apply parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
WARNING!
It is dangerous to shift the selector lever out of P
(Park) or N (Neutral) if the engine speed is higher
than idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control of the
vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
when your right foot is firmly on the brake pedal.
