Recommended Shift Speeds
To use your manual transaxle for optimal fuel economy,
it should be upshifted as listed in table.

Downshifting
Proper downshifting will improve fuel economy and
prolong engine life.
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 2nd or 1st 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.

AUTOSTICK Ð IF EQUIPPED
Autostick is 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
Continuously Variable Automatic Transaxle (CVT) and or
the engine from overspeed and changes down will only
happen at minimum engine speed to prevent stalling.
Autostick Operation
NOTE:Autostick is not functional until the CVT warms
up in cold weather.
Autostick Shifter
236 STARTING AND OPERATING

Autostick operation is activated in the9D9position by
moving the shift lever side to side. Moving the lever to
the (+) side will activate Autostick and shift up to the
next higher manual ratio, unless you are already operat-
ing in or near overdrive in which case, 6th ratio will be
selected. In like manner, moving the 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 lever to the (+) or (-) direction will cause
an upshift or downshift by one ratio.
Autostick is deactivated:
²By holding the lever to (+) momentarily.
²When the shift lever is shifted out of9D.9
²When in 6 position, touching the lever to the right.
²When heavy Anti-lock brake system (ABS) application
is detected.
Autostick General Information
²
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.
²If a low range is selected and the engine accelerates to
the rev limit, the transaxle will automatically select the
next higher ratio.
²If a downshift would cause the engine to overspeed,
that shift will not occur until it is safe for the engine.
Mostly the CVT will stay in the manually selected
ratio, however.
²If the system detects powertrain overheating, the
transmission will revert to the automatic shift mode
and remain in that mode until the powertrain cools off.
²If the system detects a problem it will disable the
Autostick mode and the transmission will return to the
automatic mode until the problem is corrected.

Trailer Towing Weights (Maximum Trailer Weight Ratings)
The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
Engine/Transmission Frontal Area Max. GTW (Gross Trailer Wt.) Max. Tongue Wt.
(See Note 1)
2.4L Auto/Man 22 Sq. Ft. (2.04 Sq. m) 1000 lbs (453 kg) 150 lbs (68 kg)
2.4L Auto/Man with
Trailer Tow Prep Pack-
age (AHC)32 Sq. Ft. (3.0 Sq. m) 2000 lbs (907 kg) 225 lbs (102 kg)
Refer to local laws for maximum trailer towing speeds.
Note 1 ± The trailer tongue weight must be considered as
part of the combined weight of occupants and cargo, and
should never exceed the weight referenced on the Tire
and Loading Information placard. Refer to the Tire±
Safety Information Section in this manual.

Towing Tips Ð Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
þCity Driving
When stopped for short periods of time, put transmission
in neutral but do not increase engine idle speed.
þHighway Driving
Reduce speed.
þAir Conditioning
Turn off temporarily.
þrefer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Towing This Vehicle Behind Another Vehicle (Flat
towing with all four wheels on the ground)
CAUTION!
DO NOT flat tow this vehicle. Damage to the driv-
etrain will result.
NOTE:If the vehicle requires towing make sure all four
wheels are off the ground.

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 Section 7, Maintenance, 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!
²Being 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.
²The 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.
298 WHAT TO DO IN EMERGENCIES

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 ªFluids, Lubricants and Genuine Partsº for correct
fluid type.
CAUTION!
Using a transmission fluid other than the manufac-
turers recommended fluid will cause belt slip and
result in a complete transmission failure! Refer to
ªFluids, Lubricants, and Genuine Partsº for 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 ªMaintenance Scheduleº in Section 8 of this
manual for the correct change 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 addi-
tives.
Manual Transaxle
Lubricant Selection
Use only the manufacturers recommended transmission
fluid. Refer to ªFluids, Lubricants, and Genuine Partsº
for correct fluid type.
