AUTOMATIC TRANSAXLE — IF EQUIPPEDYou must step on the brake pedal and depress the gear
selector lever knob button before you will be able to shift
out of PARK.
CAUTION!
Damage to the transaxle may occur if the following
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.
NOTE: You must step on the brake pedal and depress
the gear selector lever knob button before you will be
able to shift the gear selector lever out of PARK.
294 STARTING AND OPERATING

WARNING!
It is dangerous to shift the gear 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 the
gear selector lever into gear when the engine is idling
normally and when your right foot is firmly on the
brake pedal.BRAKE/TRANSMISSION INTERLOCK SYSTEMThis system prevents you from shifting the gear selector
lever out of PARK and into any gear unless the brake
pedal is pressed. This system is active only while the
ignition switch is in the ON or ACC positions.Alwaysstep on the brake pedal and depress the gear selector
lever knob button before shifting out of PARK.
NOTE:
If a malfunction occurs, the system will function
normally, except you may be able to shift the vehicle from
PARK, without depressing the brake pedal. If this occurs
obtain service from an authorized dealer as soon as
possible.
AUTOMATIC TRANSAXLE IGNITION INTERLOCK
SYSTEMThis system prevents the key from being removed unless
the gear selector lever is in PARK and the gear selector
lever knob push button is out. It also prevents shifting
out of PARK unless the key is in the ACC or ON
positions, and the brake pedal is depressed.
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 AUTOMATIC TRANSAXLEThe electronically controlled transaxle provides a precise
shift schedule. The transaxle electronics are self calibrat-
ing; therefore, the first few shifts on a new vehicle may be
somewhat abrupt. This is a normal condition, and preci-
sion shifts will develop within a few shift cycles.RESET MODEThe transaxle is monitored electronically for abnormal
conditions. If a condition is detected that could cause
damage, the transaxle shifts automatically into second
gear. The transaxle remains in second gear despite the
forward gear selected. PARK, REVERSE, and NEUTRAL
will continue to operate. This second gear limp-in feature
allows the vehicle to be driven to a dealer for service
without damaging the transaxle.In the event that the problem has been momentary, the
transaxle can be reset to regain all forward gears.
Stop the vehicle and shift the gear selector lever into
PARK.
Turn the Key to OFF then restart the engine.
Shift the gear selector lever into DRIVE and resume
driving.
If the transaxle cannot be reset, authorized dealer service
is required.
NOTE:
Even if the transaxle can be reset, it is recom-
mended that you visit an authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.296 STARTING AND OPERATING

GEAR RANGES FOR THE FOUR-SPEED
AUTOMATIC TRANSAXLEDO NOT race the engine when shifting from PARK or
NEUTRAL positions into another gear range.PARKPARK 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, and then shift the
gear selector lever into the PARK position.
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 vehicle 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, secur-
ing the vehicle against unwanted movement. Further-
more, you should never leave children unattended
inside a vehicle.
STARTING AND OPERATING 297

The following indicators should be used to ensure that
you have engaged the transmission gear selector lever
into the PARK position:•
When shifting the gear selector lever into PARK,
depress the button on the gear selector lever knob and
firmly move the lever all the way forward until it
stops.
•
Look at the shift indicator window on the console to
ensure it is in the PARK position.
•
When engaged in PARK, you will not be able to move
the gear selector lever rearward without depressing
the gear selector lever knob button
CAUTION!
Before shifting the gear selector lever out of PARK,
you must turn the ignition from LOCK to ON so the
steering wheel and gear selector lever are released.
Otherwise, damage to the steering column or gear
selector lever could result.REVERSEShift into this range only after the vehicle has come to a
complete stop.NEUTRALThe engine may be started in this range.DRIVE / OVERDRIVEThis range should be used for most city and highway
driving. It provides smoothest upshifts and downshifts,
and best fuel economy.
298 STARTING AND OPERATING

When frequent transaxle shifting occurs while using the
DRIVE/OVERDRIVE range, such as when operating the
vehicle under heavy loading conditions (in hilly terrain,
traveling into strong head winds, or while towing trail-
ers), use the[3]range.[3] DRIVEThis range eliminates shifts into OVERDRIVE. The trans-
axle will operate normally in first and second while in
this range.
NOTE: Using the [3]range while operating the vehicle
under heavy operating conditions will improve perfor-
mance, fuel economy, and extend transaxle life by reduc-
ing excessive shifting and heat build up.
Use the [3]range when descending steep grades to
prevent brake system distress.
[1] LowThis range should be used for maximum engine braking
when descending steep grades. In this range, up shifts
will occur only to prevent engine over speed while down
shifts from [2]to[1] will occur as early as possible.AUTOSTICK — IF EQUIPPEDAUTOSTICK is a driver-interactive transmission that
offers manual gear shifting capability to provide you
with more control. AUTOSTICK allows you to maximize
engine braking, 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 situa-
tions.
STARTING AND OPERATING 299

AUTOSTICK OperationThe AUTOSTICK position is just below the OVERDRIVE
position and is identified by the word “AUTOSTICK”.
When you place the gear selector lever in the
AUTOSTICK position, it can be moved from side to side.
Moving the lever to the left (-) triggers a downshift and to
the right (+) an upshift. The gear position will be shown
in the transmission gear display, located in the instru-
ment cluster.
You can shift in or out of the AUTOSTICK mode at any
time without taking your foot off the accelerator pedal. If
you choose the OVERDRIVE mode, the transmission will
operate automatically; shifting between the four avail-
able gears. When you wish to engage AUTOSTICK,
simply move the gear selector lever to the AUTOSTICK
position. The transmission will remain in the current gear
until an upshift or downshift is chosen.Move the lever back to the OVERDRIVE position to shift
out of the AUTOSTICK mode.
AUTOSTICK General Information
•
The transmission will automatically upshift from first
to second gear and from second to third gear when
engine speed reaches about 6,300 RPM.
•
Downshifts from third to second gear above 74 mph
(119 km/h) and from second to first gear above 41
mph (66 km/h) will be ignored.
•
You can start out in first, second, or third gear. Shifting
into fourth gear can occur only after vehicle speed
reaches 15 mph (24 km/h).
•
The transmission will automatically downshift to first
gear when coming to a stop.
•
Starting out in third gear is helpful in snowy or icy
conditions.

For improved performance, your manual transaxle may
be upshifted up to the maximum speeds listed in Table 2
(within legal speed limits).

If you exceed these speeds, you may notice the engine cut
in and out. This is caused by an electronic limiter in the
engine computer. The engine will run normally when
you reduce engine speed.DownshiftingProper downshifting will improve fuel economy and
prolong engine life.
CAUTION!
If you skip a gear while downshifting or downshift
at too high an engine speed, you could damage the
engine, transmission, or clutch.
304 STARTING AND OPERATING

To maintain a safe speed and prolong brake life, shift
down to SECOND or FIRST gear when descending a
steep grade.
When turning a corner, or driving up a steep grade,
downshift early so that the engine will not be overbur-
dened.PARKING BRAKE
When the parking brake is applied with the
ignition on, the BRAKE Light in the instrument
cluster will come on.
NOTE: This light only shows that the parking brake is
on. It does not show the degree of brake application. If the parking brake is applied while the vehicle is
moving, a chime will sound to alert the driver. The chime
will sound up to 10 times or until the vehicle has
returned to a stop.
Before leaving the vehicle, make sure that the parking
brake is set. To set the parking brake, pull up firmly on
the lever. Always shift the gear selector lever into the
PARK position (automatic transaxle) or into the RE-
VERSE position (manual transaxle). To release the park-
ing brake, apply the brake pedal, pull up slightly on the
lever, then depress the button on the end of the lever and
push the lever fully down toward the floor.

BRAKE SYSTEMYour vehicle is equipped with power assisted brakes as
standard equipment. In the event power assist is lost for
any reason (for example, repeated brake applications
with the engine off), the brakes will still function. How-
ever, the effort required to brake the vehicle will be much
greater than that required with the power system oper-
ating.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
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.If either of the two hydraulic systems lose normal capa-
bility, the remaining system will still function with 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. In addition, if the
malfunction is caused by an internal leak, as the brake
fluid in the master cylinder drops, the brake warning
indicator will light.
WARNING!
Driving a vehicle with the brake light on is danger-
ous. A significant decrease in braking performance 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.
