CAUTION!
If you skip more than one gear while downshifting
or downshift at too high a vehicle speed, you could
damage the engine, transmission, or clutch.
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
overburdened.
AUTOMATIC TRANSAXLE — IF EQUIPPED
NOTE: The Continuously Variable Automatic Transaxle
(CVT) changes ratios in a continuous manner. This may
sometimes “feel” as if it is slipping, but this is normal and
does not harm anything.
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 press and hold the brake pedal down
while shifting out of PARK.
282 STARTING AND OPERATING

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 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 the ON or
START position (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/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 ON position, and the brake
pedal is pressed.
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.5
STARTING AND OPERATING 283

•Look at the shift indicator window on the shift lever
bezel to ensure it is in the PARK position.
•You must press the brake pedal to move the shift lever
out of the PARK position.
CAUTION!
Before moving the shift lever out of PARK, you must
turn the ignition from LOCK to ON so the steering
wheel and shift lever are released. Otherwise, dam-
age to the steering column or shift lever could result.
You must also press the brake pedal.
REVERSE
This range is for moving the vehicle rearward. Use this
range only after the vehicle has come to a complete stop.
NEUTRAL
This range is used when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
DRIVE
This range is used for most city and highway driving.
AUTOSTICK— IF EQUIPPED
AutoStickis a driver-interactive transmission that offers
six manual ratio changes 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. Automatic ratio
changes upward will only occur to protect the Continu-
ously Variable Automatic Transaxle (CVT) and/or the5
STARTING AND OPERATING 285

engine from overspeed. Changes down will only happen
at minimum engine speed to prevent stalling.
Operation
NOTE:AutoStick is not functional until the CVT
warms up in cold weather.
AutoStick operation is activated in the DRIVE position
by moving the shift lever side-to-side. Moving the shift
lever to the (+) side will activate AutoStick and shift up
to the next higher manual ratio, unless you are already
operating in or near Overdrive, in which case sixth gear
ratio will be selected. In like manner, moving the shift
lever to (-) will activate AutoStick and shift to the next
lower manual ratio. After AutoStick is 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. AutoStick
is deactivated:
•By holding the shift lever to (+) momentarily
•When the shift lever is shifted out of DRIVE
•When in sixth position, touching the shift lever to the
right
•When heavy Anti-Lock Brake System (ABS) applica-
tion is detected
General Information
•
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.
•If a low range is selected and the engine accelerates to
the rev limit, the transaxle will automatically select the
next higher ratio.
286 STARTING AND OPERATING

•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). Where one or more wheels have wheel spin or if addi-
tional traction is needed in sand, deep snow, or loose
traction surfaces, activate the “4WD LOCK” switch by
pulling up once and releasing. This locks the center
coupling allowing more torque to be sent to the rear
wheels. The “4WD Indicator Light” will come on in the
Four-Wheel Drive Switch

WARNING! (Continued)
•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 orchock
the 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 uti-
lized (This requirement may limit the ability to
always achieve the 10% to 15% range of tongue
weight as a percentage of total trailer weight).
Towing Requirements – Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for the
proper inspection procedure.
When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for proper tire
350 STARTING AND OPERATING

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 the
requested 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.
