Automatic Transmission — General Information
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the
engine is at idle speed.
•Do not shift from REVERSE, PARK or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
The automatic transmission selects individual gears au-
tomatically, dependent upon:
•Altitude
•Vehicle Loading
•Driving Style
•Selector lever position
•Accelerator position
•Vehicle speed
The gear shifting process is continuously adapted, de-
pendent on the driving style, the driving situation and
the road characteristics.
NOTE:
•
After selecting any driving position, wait a moment to
allow the gear to fully engage before accelerating,
especially when the engine is cold.
•If there is a need to restart your engine be sure to cycle
the key to the LOCK position before restarting. Trans-
mission engagement may be delayed up to 10 seconds
after restart if the key is not cycled to the LOCK
position first.
•The electronically controlled transmission provides a
precise shift schedule. The transmission electronics are
188 STARTING AND OPERATING

self-calibrating. Therefore, the first few shifts on a new
vehicle may be somewhat abrupt or soft until after the
break-in period. This is a normal condition, and pre-
cision shifts will develop within a few shift cycles.
WARNING!
It is dangerous to shift the selector 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 foot is
firmly on the brake pedal.
The selector lever is automatically locked while in the
PARK position. To move the selector lever out of the
PARK position, the brake pedal must be firmly depressed
before the shift lock will release.
Shift the selector lever to the desired position only when
the engine is idling normally and the brake pedal isapplied. Do not release the brake until ready to drive. The
vehicle may otherwise accelerate quickly when the selec-
tor lever is in DRIVE or REVERSE position.
Stopping
For brief stops, leave the transmission in gear and hold
the vehicle with the brake pedal. For longer stops with
the engine idling, shift into the NEUTRAL or PARK
position and hold the vehicle with the parking brake.
When stopping the vehicle uphill, do not hold it with the
accelerator; use the brake. This avoids unnecessary trans-
mission heat build-up.
Maneuvering
To maneuver in tight areas, control the vehicle speed by
gradually releasing the brakes. Accelerate gently and
never abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow),
alternately shift from forward to reverse, while applying
only slight acceleration. Rocking a vehicle free in this
manner may cause the ABS or traction system malfunc-
tion indicator light to come on. Turn off the engine and
restart the engine to clear the malfunction indication.

Brake Transmission Shift Interlock System
This vehicle is equipped with a brake transmission shift
interlock system (BTSI) that holds the gearshift lever in
the P (Park) position when the ignition switch is in the
LOCK position. To move the gear selector lever out of the
P (Park) position, the ignition switch must be turned to
the ON position, and the brake pedal must be depressed.
Over Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission exceeds
normal operating temperature, the transmission will
change the way it shifts to help control the condition.
This may result in a slightly different feeling or response
during normal operation in D (Drive) position. After the
transmission cools down, it will return to normal opera-
tion.
AUTOSTICK
Autostick is a driver-interactive transmission that offers
manual gear shifting capability to provide the driver
with more control. Autostick allows the driver to increase
engine braking ability, eliminate undesirable upshifts
and downshifts, and improve overall vehicle perfor-
mance. This system can also provide the driver with
more control during passing, city driving, mountain
driving, trailer towing, and many other situations.
Autostick Operation
By placing the shift lever in the DRIVE position the lever
can be moved from side to side. This allows the driver to
select a specific gear. Move the shift lever to the Left (-) to
trigger a downshift and to the Right (+) to trigger an
upshift. The gear position will be shown in the transmis-
sion gear display located in the instrument cluster.
NOTE:In the autostick mode the transmission will only
shift up and down when Left or Right (D-/D+) is
manually selected by the driver.
Shifting into or out of the autostick mode can be done at
any time without taking your foot off the accelerator
190 STARTING AND OPERATING

pedal. When the driver wishes to engage autostick,
simply move the shift lever to the Left or Right(D-/D+)
position while in DRIVE.
Hold the shift lever to the right for at least one second to
disengage autostick. The transmission will now operate
automatically; shifting between the five available gears.
Autostick General Information
•
You can start out in first or second gear. The system will
ignore attempts to upshift at too low of a vehicle speed.
•The transmission will automatically downshift to first
gear when coming to a stop.
•Starting out in second gear is helpful in snowy or icy
conditions.
•Avoid using speed control when autostick is engaged.
•The transmission will not automatically shift up when
maximum engine speed is reached while autostick is
engaged.
•Transmission shifting will be more noticeable when
autostick is engaged.
PARKING BRAKE
When the parking brake is applied with the ignition
switch on, the brake light in the instrument cluster will
turn on.
NOTE:This light only shows that the parking brake is
applied. It does not show the degree of brake application.
Before leaving the vehicle, make sure that the parking
brake is fully applied and place the gear selector in the
Park position.

BRAKE SYSTEM
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.
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems lose normal capability, the remaining
system will still function. There will be some
loss of overall braking effectiveness. This may be evident
by increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Lamp.
Anti-Lock Brake System
The Anti-Lock Brake System provides increased vehicle
stability and brake performance under most braking
conditions. The system automatically “pumps” the
brakes during severe braking conditions to prevent
wheel lock-up.The electronic brake force distribution (EBD) prevents the
rear wheels from over-braking and provides greater
control of available braking forces applied to the rear
axle.
WARNING!
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
STARTING AND OPERATING 193

These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season type
tires. Rotation will increase tread life, help to maintain
mud, snow, and wet traction levels, and contribute to a
smooth, quiet ride.
GROUND CLEARANCE
CAUTION!
Damage to the front and rear fascias can occur if you
disregard the low ground clearance in the front and
rear of this vehicle. Pay close attention when parking
to avoid running into parking curbs. Exercise caution
when entering or exiting steep driveways or when
pulling off the road onto soft shoulders.
FUEL REQUIREMENTS
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high quality pre-
mium unleaded gasoline having an octane
rating of 91 or higher.
Spark Knock
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of “premium” gasoline
before considering service for the vehicle.
Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) to define
fuel properties necessary to deliver enhanced emissions,
engine performance, and durability for your vehicle. The
manufacturer recommends the use of gasolines that meet
the WWFC specifications if they are available.
214 STARTING AND OPERATING

Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline”.
Reformulated gasolines contain oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol. Use of
these blends may result in starting and driveability
problems and may damage critical fuel system com-
ponents.
Problems that result from using methanol/gasoline
blends are not the responsibility of the manufacturer.
While MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane num-
ber. Gasolines blended with MMT offer no performance
advantage beyond gasolines of the same octane number
without MMT. Gasolines blended with MMT have shown
to reduce spark plug life and reduce emission system
performance in some vehicles. The manufacturer recom-
mends using gasolines without MMT. Since the MMT
STARTING AND OPERATING 215

content of gasoline may not be indicated on the pump,
you should ask your gasoline retailer whether or not
his/her gasoline contains MMT.
It is even more important to look for gasolines without
MMT in Canada, because MMT can be used at levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated gasolines.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives are not needed under
normal conditions and would result in additional cost.
Therefore you should not have to add anything to the
fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
or damage the emission control system.
•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out-of-tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
•The use of fuel additives which are now being sold as
octane enhancers are not recommended. Most of these
products contain high concentrations of methanol.
