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.
Brake/Transmission Interlock System
This system prevents you from moving the shift 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. Always depress the
brake pedal first,before moving the shift lever out of
PARK.NOTE:If a malfunction occurs, the transaxle will not
shift out of PARK. Battery power is required to release the
brake/transmission interlock system. There is a remov-
able plug in the right side of the shift lever housing that
allows you to insert your finger to override the system.
The key must be in the ignition and in the ON position to
use the override lever. If this occurs obtain service as
soon as possible.
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 key is in the ACC or ON position, 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.

AUTOSTICK— IF EQUIPPED
Autostickis a driver-interactive transmission that offers
six manual ratio changes to provide you with more
control. Autostickallows 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 driv-
ing, cold slippery conditions, mountain driving, trailer
towing, and many other situations. Automatic ratio
changes upward will only occur to protect the Continu-
ously Variable Automatic Transaxle (CVT) and/or the
engine from overspeed. Changes down will only happen
at minimum engine speed to prevent stalling.
Operation
NOTE:Autostickis not functional until the CVT
warms up in cold weather.
Autostickoperation is activated in the DRIVE position
by moving the shift lever side-to-side. Moving the shiftlever to the (+) side will activate Autostickand shift up
to the next higher manual ratio, unless you are already
operating in or near Overdrive, in which case 6th ratio
will be selected. In like manner, moving the shift lever to
(-) will activate Autostickand shift to the next lower
manual ratio. After Autostickis activated, the manual
ratio selected is displayed in the transmission ratio
display and tipping the shift lever to the (+) or (-)
direction will cause an upshift or downshift by one ratio.
Autostickis deactivated:
•By holding the shift lever to (+) momentarily
•When the shift lever is shifted out of DRIVE
•When in 6th position, touching the shift lever to the
right
•When heavy Anti-Lock Brake System (ABS) applica-
tion is detected
260 STARTING AND OPERATING

General Information
•
If a ratio other than 1st is selected and the vehicle is
brought to a stop, the transaxle control logic will
automatically select the 1st gear ratio.
•If a low range is selected and the engine accelerates to
the rev limit, the transaxle will automatically select the
next higher ratio.
•If a downshift would cause the engine to overspeed,
that shift will not occur until it is safe for the engine.
However. the CVT will stay in the manually selected
ratio.
•If the system detects powertrain overheating, the
transmission 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
Autostickmode and the transmission will return to
the automatic mode until the problem is corrected.
FOUR-WHEEL DRIVE OPERATION — IF
EQUIPPED
This feature provides full time, on-demand, four–wheel
drive (4WD).

•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
PARK. Always block orchockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight).
322 STARTING AND OPERATING

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Towing Tips — Automatic Transmission
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. Refer to the “Main-
tenance Schedule” in Section 8 for transmission fluid
change intervals.
NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips — Electronic Speed Control (If
Equipped)

Do not use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips — Cooling System
To reduce the potential for engine and transmission
overheating, take the following actions:
City Driving
When stopped for short periods of time, put transmission
in NEUTRAL but do not increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
326 STARTING AND OPERATING

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to “Maintenance”, Section 7 of
this manual. Follow the warnings under the “Cooling
System Pressure Cap” paragraph.
AUTOMATIC TRANSAXLE OVERHEATING
During sustained high speed driving or trailer towing up
long grades on hot days, the automatic transaxle oil may
become too hot.
If this happens, the transmission overheat in-
dicator light will come on, and the vehicle will
slow slightly until the automatic transaxle
cools down enough to allow a return to therequested speed. If the high speed is maintained, the
overheating will reoccur, as before, in a cyclic fashion.
JACKING AND TIRE CHANGING
WARNING!
•Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you
need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
•The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.
332 WHAT TO DO IN EMERGENCIES

5. Turn on the Hazard Warning flasher.
6. Block both the front and rear of the
wheel diagonally opposite the jacking
position. For example, if changing the
right front tire, block the left rear
wheel.
NOTE:Passengers should not remain in the vehicle
while the vehicle is being jacked.

3. Using the two finger screws on the cover, remove the
air intake duct covering the battery.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the jumper cable to the positive terminal of the dis-
charged battery.WARNING!
•Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or cloth-
ing. Don’t lean over the battery when attaching the
clamps or allow the clamps to touch each other. If
acid splashes in your eyes or on your skin, flush
the contaminated area immediately with large
quantities of water.
•A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away
from the vent holes. Do not use a booster battery
or any other booster source with an output that
exceeds 12-Volts.
5. Connect the other cable, first to the negative terminal
of the booster battery and then to the negative terminal of
the discharged battery. Make sure you have a good
contact.

Automatic Transaxle (CVT)
Selection Of Lubricant
It is important that the proper lubricant is used in the
transaxle to assure optimum transaxle performance. Use
only the manufacturer’s recommended transmission
fluid which has been formulated with special metal to
metal friction coefficient additives to provide the proper
steel belt traction on the drive and driven pulleys. Refer
to “Fluids, Lubricants, and Genuine Parts” in this section
for the correct fluid type.
CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid will cause belt slip and
result in a complete transmission failure! Refer to
“Fluids, Lubricants, and Genuine Parts” in this sec-
tion for the correct fluid type.
Fluid Level Check
The fluid level in the automatic transaxle should be
checked only by a trained technician.
Fluid And Filter Changes
Refer to the “Maintenance Schedule” in Section 8 for the
correct maintenance interval.
Special Additives
Do not add any materials (other than leak detection dyes)
to Continuously Variable Transaxle (CVT) Fluid
(CVTF+4). CVTF+4 is an engineered product and its
performance may be impaired by supplemental
additives.
Manual Transaxle
Lubricant Selection
