Remote Start mode for a 15 minute cycle.
26 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbag Warning Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objectslodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To Activate
1. Select “Auto High Beams.” Refer to “Electronic Ve-
hicle Information Center (EVIC)/Customer-
Programmable Features” in “Understanding Your Instru-
ment Panel” for further information.
2. Turn the end of the multifunction lever to the AUTO
headlight position.
3. Push the multifunction lever away from you (toward
front of vehicle) to engage the high beam mode.
NOTE:This system will not activate until the vehicle is
at or above 20 mph (32 km/h).
To Deactivate
1. Pull back on the multifunction lever to manually
deactivate the system (normal operation of low beams). 2. Push back on the multifunction lever once again to
reactivate the system.
NOTE:
Broken, muddy, or obstructed headlights and
taillights of vehicles in the field of view will cause
headlights to remain on longer (closer to the vehicle).
Also, dirt, film, and other obstructions (sticker, toll box,
etc.) on the windshield or camera lens will cause the
system to function improperly.
Daytime Running Lights — If Equipped
The high beam headlights come on at a low intensity
level whenever the engine is running, and the transmis-
sion is not in the PARK position. The lights will remain
on until the ignition switch is turned to LOCK/ACC or
the parking brake is engaged. The headlight switch must
be used for normal nighttime driving.
104 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

INSTRUMENT CLUSTER DESCRIPTIONS
1. Speedometer
Indicates vehicle speed.
2. Brake Warning LightThis light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Program (ESP) sys-
tem. In this case, the light will remain on until the
condition has been corrected. If the problem is related to the brake booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be felt during
each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.

WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
an accident. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON position. The light should illuminate for approxi-
mately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is detected.
If the light does not illuminate, have the light inspected
by an authorized dealer. The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.
3. Turn Signal Indicator The arrows will flash with the exterior turn signals
when the turn signal lever is operated. A tone will
chime if the turn signals are left on for more than 1 mile
(1.6 km).
4. High Beam Indicator Indicates that headlights are on high beam.
5. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in

236 STARTING AND OPERATING

Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position. To move the shift lever out of the PARK
position, the ignition switch must be turned to the ON or
START position (engine running or not) and the brake
pedal must be pressed.
Brake/Transmission Interlock Manual Override
Your vehicle may be equipped with a shift lock manual
override. The manual override may be used in the event
that the shift lever should fail to move from PARK with
the ignition switch in the ON position and the brake
pedal pressed. To operate the shift lock manual override,
perform the following steps:
1. Turn the ignition switch to the ON position without
starting the engine.
2. Firmly set the parking brake.3. Using a flat-bladed screwdriver, carefully remove the
shift lock manual override cover, which is located on the
PRNDL bezel.
4. Press and maintain firm pressure on the brake pedal.
5. Using the screwdriver, reach into the manual override
opening. Press and hold the shift lock lever down.
Interlock Manual Override
244 STARTING AND OPERATING

6. Move the shift lever into the NEUTRAL position.
7. The vehicle may then be started in NEUTRAL.
Have your vehicle inspected by your local authorized
dealer if the shift lock manual override has been used.
Five–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
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles/kilometers.
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 turn the
ignition switch to the LOCK position before restarting. Transmission gear engagement may be delayed after
restarting the engine if the ignition switch is not turned to
the LOCK position first.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Apply
the parking brake when leaving the vehicle in this range.
Always apply the parking brake first, then place the shift
lever into the PARK position.
WARNING!
•Never use the PARK position as a substitute for
the parking brake. Always apply the parking
brake fully when parked to guard against vehicle
movement and possible injury or damage.

STARTING AND OPERATING 245

WARNING! (Continued)
•It is dangerous to move the shift lever out of PARK
or 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.
REVERSE
This range is for moving the vehicle backward. Use only
after the vehicle has come to a complete stop.
NEUTRAL
This range is used when vehicle is standing for pro-
longed periods with engine running. Engine may be
started in this range. Set the parking brake if you must
leave the vehicle.NOTE:
Towing the vehicle, coasting, or driving for any
other reason with the shift lever in NEUTRAL can result
in severe transmission damage. Refer to “Recreational
Towing” in “Starting and Operating” and “Towing a
Disabled Vehicle” in “What To Do In Emergencies” for
further information.
DRIVE
This range is used only when the vehicle is at a complete
stop and the brakes are firmly applied. The transmission
automatically upshifts through fifth gear. The DRIVE
position provides optimum driving characteristics under
all normal operating conditions.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows
you to move the shift lever left (-) or right (+) when the
shift lever is in the DRIVE position, allowing you to limit
the highest available gear. For example, if the driver
246 STARTING AND OPERATING

When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at
the same speed. The 4WD LOW position is intended for
loose, slippery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may cause
increased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
