while the ignition switch is in the ON position. Always
press the brake pedal first before moving the gear selec-
tor lever out of PARK.
Automatic Transmission Ignition Interlock System
For electrical system malfunctions, there is an override
for the interlock system. In order to override this system,
remove the cover located to the top right of the gear
selector lever in the instrument panel. The override can
be activated by pressing the white-colored tab, which can
be accessed through the hole in the instrument panel.
While the override is pressed, the gear selector lever can
be moved out of the PARK position without pressing the
brake pedal. After operation, return the cover to its
original position.
This system prevents the key from being removed unless
the gear selector lever is in PARK. It also prevents shifting
the gear selector lever out of PARK unless the key is in
the LOCK/OFF or ON positions.NOTE:If a malfunction occurs, the system will trap the
key in the ignition cylinder to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
Four-Speed or Six-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).
The transmission has only PRND shift positions. Down-
shifts are carried out by an Electronic Range Select (ERS)
by moving the leverÐ/+while in the DRIVE position,

the instrument cluster will display transmission gear
selection as 6, 5, 4, 3, 2, 1 for six-speed and 4, 3, 2, 1 for
four-speed transmissions.
Gear Ranges
DO NOT race the engine when shifting the gear selector
lever from PARK or NEUTRAL positions into another
gear range.
PARK
Shifting the gear selector lever in PARK supplements the
parking brake by locking the transmission. The engine
can be started in this gear. Never attempt to use PARK
while vehicle is in motion. Apply the parking brake when
leaving the vehicle in this gear.
When parking on a flat surface, place the shift lever in the
PARK position first, and then apply the parking brake.When parking on a hill, it is important to set the parking
brake before placing the shift lever in PARK, otherwise
the load on the transmission locking mechanism may
make it difficult to move the shift lever out of PARK. As
an added precaution, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
WARNING!
Never use PARK position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
330 STARTING AND OPERATING

WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should always
shift the gear selector lever into PARK, remove the
key from the ignition, and apply the parking brake.
Once the key is removed from the ignition, the
transmission gear selector lever is locked in the
PARK position, securing the vehicle against un-
wanted movement. Furthermore, you should never
leave unattended children or pets inside a vehicle.
The following indicators should be used to ensure that
you have engaged the transmission gear selector lever
into the PARK position:
²When shifting the gear selector lever into PARK,
depress the button on the gear selector lever and
firmly move the lever all the way forward until it
stops.
²Look at the shift indicator window on the console to
ensure gear selector lever is in the PARK position.
²When engaged in PARK, you will not be able to move
the gear selector lever rearward without depressing
the gear selector lever button.
CAUTION!
Before moving the gear selector lever out of PARK,
you must turn the ignition from LOCK/OFF to ON so
the steering wheel and gear selector lever are re-
leased. Otherwise, damage to the steering column or
gear selector lever could result.

REVERSE
Use REVERSE for moving the vehicle rearward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL
Shift the gear selector lever into this gear only after the
vehicle has come to a complete stop. The engine may be
started in this range.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have an accident.
DRIVE Ð Six-Speed Transmission
This range should be used for most city and highway
driving. It provides the smoothest upshifts, downshifts,
and best fuel economy. However, use the Electronic
Range Select (ERS) mode by moving the leverÐ/+and
select the ª5º range when frequent transmission shifting
occurs while using the DRIVE range, such as when
operating the vehicle under heavy loading conditions,
(i.e., in hilly terrain, traveling into strong head winds or
while towing heavy trailers). Under these conditions,
using the ª5º range will improve performance and
extend transmission life by reducing excessive shifting
and heat build-up.
DRIVE Ð Four-Speed Transmission
This range should be used for most city and highway
driving. It provides the smoothest upshifts, downshifts,
and best fuel economy. However, select the ª3º range
when frequent transmission shifting occurs while using
the DRIVE range, such as when operating the vehicle
332 STARTING AND OPERATING

under heavy loading conditions, (i.e., in hilly terrain,
traveling into strong head winds or while towing heavy
trailers). Under these conditions, using the ª3º range will
improve performance and extend transmission life by
reducing excessive shifting and heat build-up.
CAUTION!
If the transmission operating temperature exceeds
acceptable limits, the vehicle computer will override
DRIVE and select ª5º range (on six-speed transmis-
sions) or ª3º range (on four-speed transmissions) by
changing shift points. This is done to prevent trans-
mission damage due to overheating.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows
you to move the gear selector lever to the left (-) or right
(+) when the gear selector lever is in the D (Drive)position, this allows the selection of the desired top gear.
For example, if the driver shifts the transmission into 3rd
gear, the transmission will never shift above 3rd gear, but
can shift down to 2nd or 1st gear automatically, when
needed.
Switching from ERS to D-Mode (Drive) can be done at any
vehicle speed. To shift from ªDriveº mode to ªERSº mode,
move gear selector lever to the left (-) once. The current gear
will be maintained as the top gear. To disable ERS, simply
press and hold the gear selector lever to the right (+) until
ªDº is displayed in the instrument cluster odometer.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid causing an accident or
personal injury.

NOTE:To select the proper gear position for maximum
deceleration (engine braking), simply press and hold the
gear selector lever to the left (-). The transmission will
shift to the range from which the vehicle can best be
slowed down.Reset Mode - Electronic Transmission
The transmission is monitored electronically for abnor-
mal conditions. If a condition is detected that could cause
damage, the transmission automatically shifts into 2nd
gear (3rd gear for six-speed). The transmission remains in
2nd gear (3rd gear for six-speed) despite the forward gear
selected. PARK, REVERSE, and NEUTRAL will continue
to operate. This Reset feature allows the vehicle to be
driven to an authorized dealer for service without dam-
aging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift into PARK.
3. Turn the ignition switch to the LOCK position.
4. Restart the engine.
334 STARTING AND OPERATING

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. However, there will
be some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application and
greater pedal force required to slow or stop the vehicle. In
addition, if the malfunction is caused by a leak in the
hydraulic system, the brake warning indicator will turn
on as the brake fluid level drops in the master cylinder.
In the event power assist is lost for any reason (for
example, repeated brake applications with the engine
off), the brakes will still function. The effort required to
brake the vehicle will be much greater than that required
with the power system operating.WARNING!
²Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot rest-
ing or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. You
wouldn't have your full braking capacity in an
emergency.
²Driving a vehicle with the brake light on is dan-
gerous. A significant decrease in braking perfor-
mance or vehicle stability during braking may
occur. It will take you longer to stop the vehicle or
will make your vehicle harder to control. You
could have an accident. Have the vehicle checked
immediately.

to the ABS system is required. Consult with your autho-
rized dealer service center as soon as possible.
ELECTRONIC BRAKE CONTROL SYSTEMS
Your vehicle is equipped with an advanced electronic
brake control system that includes TCS (Traction Control
System), BAS (Brake Assist System) and ESP (Electronic
Stability Program). These systems complement the Anti-
Lock Brake System (ABS) by optimizing the vehicle
braking capability during emergency braking maneu-
vers.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle isspinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if the ESP is in the
ªPartial Offº mode.
The Traction Control System (TCS) Indicator
Light, located in the instrument cluster, starts
to flash as soon as the tires lose traction and the
wheels begin to spin. This indicates that the
TCS is active. If the indicator light flashes during accel-
eration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions, and do not
switch off the ESP or TCS.
340 STARTING AND OPERATING

WARNING!
²BAS (Brake Assist System) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevail-
ing road conditions.
²BAS cannot prevent accidents, including those
resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. Only a
safe, attentive, and skillful driver can prevent
accidents.
²The capabilities of a BAS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user's safety
or the safety of others.
Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counter-
acting the over/under steer condition. Engine power
may also be reduced to help the vehicle maintain the
desired path.
ESP uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESP applies the brake of the appropri-
ate wheel to assist in counteracting the oversteer or
understeer condition.
²Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
²Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
342 STARTING AND OPERATING

ESP ON
This is the normal operating mode for ESP on 2WD
vehicles. Whenever the vehicle is started, the ESP system
will be in this mode. This mode should be used for most
driving situations. ESP should only be turned off for
specific reasons as noted below.
ESP Partial OFF
This mode is entered by momentarily depressing the ESP
OFF switch (located in the center switch bank, next to the
hazard flasher switch).
When in Partial OFF mode, the TCS portion of
ESP, except for the ªlimited slipº feature de-
scribed in the TCS section, has been disabled
and the ESP/TCS Indicator Light will be illu-
minated. All other stability features of the ESP function
normally. This mode is intended to be used if the vehicle
is in deep snow, sand or gravel conditions and more
wheel spin than ESP would normally allow is required togain traction. To turn ESP on again, momentarily depress
the ESP OFF switch. This will restore the normal ESP ON
mode of operation.
NOTE:To improve the vehicle's traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the Partial OFF
mode by pressing the ESP OFF switch. Once the situation
requiring ESP to be switched to the Partial OFF mode is
overcome, turn ESP back on by momentarily depressing
the ESP OFF switch. This may be done while the vehicle
is in motion.
ESP/BAS Warning Light
The malfunction indicator light for the ESP is
combined with BAS. The ESP/BAS Warning
light and the ESP/TCS Indicator Light in the
instrument cluster both come on when the
ignition switch is turned to the ON position. They should
go out with the engine running. If the ESP/BAS Warning
