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.
STARTING AND OPERATING 211

•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
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 is
applied. 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.
212 STARTING AND OPERATING

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—If Equipped
Autostick is a driver-interactive transmission that offers
manual gear shifting capability to provide you with more
control. Autostick allows you to maximize engine brak-
ing, eliminate undesirable upshifts and downshifts, and
improve overall vehicle performance. This system can
also provide you with more control during passing, city
driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Autostick Operation
By placing the shift lever in the DRIVE position it can be
moved from side to side. This allows the driver to select
a higher or lower range of gear ratios. Moving the lever
to the left (-) triggers a downshift and to the right (+) an
upshift. The gear position will be shown in the transmis-
sion gear display, located in the instrument cluster.
STARTING AND OPERATING 213

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.
216 STARTING AND OPERATING

WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious accident. Don’t drive a vehicle loaded to the
maximum capacity at continuous speeds above 75
mph (120 km/h).
Radial-Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial ply tires in sets of four (or 6, in case
of trucks with dual rear wheels). Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.
Compact Spare Tire—If Equipped
The compact spare is for temporary emergency use with
radial tires. It is engineered to be used on your style
vehicle only. Since this tire has limited tread life, the
original tire should be repaired (or replaced) and rein-
stalled at the first opportunity.
WARNING!
Temporary use spare tires are for emergency use
only. With these tires, do not drive more than 50 mph
(80 km/h). Temporary-use spare tires have limited
tread life. When two or more tread wear indicators
appear in adjacent grooves, the temporary use spare
tire needs to be replaced. Be sure to follow the
warnings which apply to your spare. Failure to do so
could result in spare tire failure and loss of vehicle
control.

FUEL REQUIREMENTS
Your vehicle is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and performance when us-
ing high quality unleaded gasoline having
an octane of 87.
The manufacturer recommends the use of
89 octane for optimum performance. The
use of premium gasoline is not recom-
mended.
Continued heavy spark knock can cause engine 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 gasoline before consid-
ering 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.
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.

vehicle may be sold nationwide. Your vehicle will oper-
ate satisfactorily on fuels meeting Federal specification,
but emission control system performance may be ad-
versely affected.
Gasoline sold outside of California is permitted to have
higher sulfur levels which may affect the performance of
the vehicle’s catalytic converter. This may cause the
Malfunction Indicator Light to illuminate. The manufac-
turer recommends that you try a different brand of
unleaded gasoline having lower sulfur to determine if the
problem is fuel related prior to returning your vehicle to
an authorized dealer for service.
CAUTION!
If the Malfunction Indicator light is flash-
ing, immediate service is required. Refer to
the paragraph on the Onboard Diagnostics
System in section 7 of this manual.
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,
damage the emission control system, and could result
in loss of warranty coverage.
•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
STARTING AND OPERATING 245

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.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives are not
the responsibility of the manufacturer and may not be
covered under the New Vehicle Warranty.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
•Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
•Keep the trunk closed when driving your vehicle to
prevent carbon monoxide and other poisonous ex-
haust gases from entering the vehicle.
246 STARTING AND OPERATING

NOTE:
•
Tighten the gas cap until you hear a“clicking”sound.
This is an indication that the gas cap is properly
tightened. If the gas cap is not secured properly the
Malfunction Indicator Light in the instrument cluster
will turn on. Make sure that the gas cap is tightened
each time the vehicle is refueled.
•When the fuel nozzle“clicks”or shuts off, the fuel
tank is full.
WARNING!
•Remove the fuel tank filler tube cap (gas cap)
slowly to prevent fuel spray from the filler neck
which may cause injury.
•The volatility of some gasolines may cause a
buildup of pressure in the fuel tank that may
increase while you drive. This pressure can result
in a spray of gasoline and/or vapors when the cap
is removed from a hot vehicle. Removing the cap
slowly allows the pressure to vent and prevents
fuel spray.
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
•Never add fuel to the vehicle when the engine is
running.
•A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
248 STARTING AND OPERATING

•Extended driving at high RPM should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPM. Return to a higher gear range or vehicle
speed when road conditions and RPM level allows.
