AUTOMATIC TRANSAXLE
CAUTION!
Damage to the transaxle may occur if the following
precautions are not observed:
•Shift the shift lever into PARK only after the
vehicle has come to a complete stop.
•Shift the shift lever 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 the shift lever from REVERSE, PARK,
or NEUTRAL into any forward gear when the
engine is above idle speed.
•Before shifting the shift lever into any gear, make
sure your foot is firmly on the brake pedal.
NOTE: You MUST press and hold the brake pedal down
while shifting the shift lever out of PARK.
WARNING!
•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.

WARNING! (Continued)
•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 shift lever is locked in the PARK position,
securing the vehicle against unwanted movement.
Furthermore, you should never leave children un-
attended inside a vehicle.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
prior to rotating the key to the LOCK position. The keycan only be removed from the ignition when the ignition
is in the LOCK position and once removed the shift lever
is locked in PARK.
Brake/Transaxle 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 any other
switch position (ACC, ON, or START) (engine running or
not) and the brake pedal must be pressed.
NOTE:
If a malfunction occurs, the transaxle will not
shift out of PARK. Battery power is required to release the
Brake/Transaxle Interlock system. However, an override
system allows you to shift out of PARK in case of loss of
power. To activate the override system:
•Firmly apply the parking brake.
240 STARTING AND OPERATING

•Insert the ignition key into the ignition switch and
rotate it to the ON position.
•Remove the cup holder liner.
•Insert a key, screwdriver, or finger into the hole at the
front of the cup holder and push and hold the manual
override release lever forward.
•While holding the release lever forward, move the
shift lever from PARK to NEUTRAL.
•Release the manual override.
NOTE: If this occurs, even if the override is successful,
it is recommended that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
Automatic Transaxle Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the ignition switch is in the ON position,
and the brake pedal is applied.
NOTE: If a malfunction occurs, the system will trap the
key in the ignition switch lock 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.

STARTING AND OPERATING 241

Four-Speed/Six-Speed Automatic Transaxle
The electronically controlled transaxle provides a precise
shift schedule. The transaxle 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
PARK
This range supplements the parking brake by locking the
transaxle. The engine can be started in this range. Never
attempt to use PARK while vehicle is in motion. Apply
parking brake when leaving vehicle in this range.
When parking on a flat surface, place the shift lever into
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 transaxle 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.

242 STARTING AND OPERATING

WARNING!
Never use PARK as a substitute for the parking
brake. Always apply parking brake fully when
parked to guard against vehicle movement and pos-
sible injury or damage.
CAUTION!
DO NOT race the engine when shifting from PARK
or NEUTRAL positions into another gear range as
this can damage the drivetrain.
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.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition switch 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 – Six-Speed Transaxle
This range should be used for most city and highway
driving. It provides the smoothest upshifts, downshifts,
and best fuel economy. However, use the AutoStick
mode and select the appropriate gear when frequent
5
STARTING AND OPERATING 243

LOW — Four-Speed Transaxle
This range should be used for engine braking when
descending very steep grades. In this range, upshifts will
occur only to prevent engine overspeed while downshifts
occur earlier than other gear range selections.
CAUTION!
If the transaxle operating temperature exceeds ac-
ceptable limits, the vehicle computer will override
DRIVE (OVERDRIVE) and [5] for six–speed
AutoSticktransaxle and [3] for four–speed trans-
axle, range by changing shift points. This is done to
prevent transaxle damage due to overheating.
Reset Mode - Electronic Transaxle
The transaxle is monitored electronically for abnormal
conditions. If a condition is detected that could cause
damage, the transaxle automatically shifts into second
gear (third gear for six–speed). The transaxle remains in second gear (third gear for six–speed) despite the for-
ward gear selected. PARK, REVERSE, and NEUTRAL
will continue to operate. The Reset feature allows the
vehicle to be driven to a dealer for service without
damaging the transaxle.
In the event of a momentary problem, the transaxle can
be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the shift lever into PARK.
3. Turn the ignition switch to the LOCK position.
4. Restart the engine.
5. Shift the shift lever into the desired gear range and
resume driving.
5
STARTING AND OPERATING 245

NOTE:Even if the transaxle can be reset, it is recom-
mended that you visit a dealer at your earliest possible
convenience. Your dealer has diagnostic equipment to
determine if the problem could recur.
If the transaxle cannot be reset, dealer service is required.
AUTOSTICK — IF EQUIPPED
AutoStickis a driver-interactive transaxle that offers six
manual ratio changes to provide you with more control.
AutoStick allows you to maximize engine braking,
eliminate undesirable upshifts and downshifts, and im-
prove 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.
Operation
By placing the shift lever one shift-level below the DRIVE
position, it can be moved from side to side. This allows
the driver to select a higher or lower range of gears. Moving the shift lever to the left (-) triggers a downshift
and to the right (+) an upshift. The gear position will
display in the instrument cluster on the transaxle range
indicator.
NOTE:
In Autostick mode, the transaxle will only shift
up or down when the driver moves the shift lever to the
right (+) or left (-).
AutoStick is deactivated when the shift lever is moved
from the AutoStick (+/-) position into the DRIVE
position.
General Information
•
You can start out, from a stop, in any gear except sixth.
The system will ignore attempts to upshift at too low
of a vehicle speed.
•If a ratio other than first is selected, and the vehicle is
brought to a stop, the transaxle control logic will
automatically select the first gear ratio.
246 STARTING AND OPERATING

•Starting out in second gear is helpful in snowy or icy
conditions.
•Avoid using speed control when Autostickis engaged.
•The transaxle will automatically shift up when maximum
engine speed is reached while Autostickis engaged.
•Transaxle shifting will be more noticeable when
Autostickis engaged.
•If a downshift would cause the engine to overspeed,
that shift will not occur until it is safe for the engine.
Mostly the transaxle will stay in the manually selected
ratio, however.
•If the system detects powertrain overheating, the
transaxle will revert to the automatic shift mode and
remain in that mode until the powertrain cools off.
•If the system detects a problem, it will disable the
AutoStick mode and the transaxle will return to the
automatic mode until the problem is corrected.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the front wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the front
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the
front wheels. You could lose control of the vehicle
and possibly have an accident. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet, mud, loose sand, etc.).

STARTING AND OPERATING 247

Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Caution
and Warning before doing so.
CAUTION!
•Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
•Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing wa-
ter.
•Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.(Continued)
CAUTION! (Continued)
•Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission/transaxle, axle, etc.) for signs of con-
tamination (i.e., fluid that is milky or foamy in
appearance) after driving through standing water.
Do not continue to operate the vehicle if any fluid
appears contaminated, as this may result in further
damage. Such damage is not covered by the New
Vehicle Limited Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
5
STARTING AND OPERATING 249

WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
•Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.
