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.

WARNING!
It is dangerous to shift the selector lever out of P
(Park) or N (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 gear shift out
of P (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 gear selector out of
P (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 shifter 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 P (Park). It also prevents shifting out
of P (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.

Gear Ranges For Continuously Variable
Automatic Transaxle (CVT)
DO NOT race the engine when shifting from P (Park) or
N (Neutral) positions into another gear range.
P (Park)
Supplements the parking brake by locking the transmis-
sion. The engine can be started in this range. Never use P
(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 place the selector
in P (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 P (Park), remove the key from
the ignition, and apply the parking brake. Once the
key is removed from the ignition, the transmission
shift lever is locked in the P (Park) position, securing
the vehicle against unwanted movement. Further-
more, you should never leave children unattended
inside a vehicle.
234 STARTING AND OPERATING

The following indicators should be used to ensure that
you have engaged the transmission shift lever into the P
(Park) position:
²When shifting into P (Park), firmly move the lever all
the way forward until it stops.
²Look at the shift indicator window on the shifter bezel
to ensure it is in the P (Park) position.
²You must depress the brake pedal to move the shift
lever out of the P (Park) position.
CAUTION!
Before moving the shift lever out of P (Park), you
must turn the ignition from LOCK to ON so the
steering wheel and shift lever are released. Other-
wise, damage to the steering column or shifter could
result. You must also depress the brake pedal.
R (Reverse)
Shift into this range only after the vehicle has come to a
complete stop.
N (Neutral)
Engine may be started in this range.
D (Drive)
This should be used for most driving and provides the
best ratio for optimum driveability, fuel economy, and
performance.
L (Low)
This range should be used for maximum engine braking
when descending steep grades. In this range, the trans-
axle will ratio up only to prevent transaxle damage or
engine over speed while ratioing down will occur as
early as possible

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.

Flowing/Rising Water
WARNING!
Do not drive on or cross a road or a path where water
is flowing and/or rising (as in storm run-off). Flow-
ing water can wear away the road or path's surface
and cause your vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can carry
your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following before
doing so:
CAUTION!
²Always 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.
²Determine 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 water.
²Do not exceed 5 mph (8 km/h) when driving through
standing water. This will minimize wave effects.
²Driving through standing water may cause damage to your
vehicle's drivetrain components. Always inspect your vehi-
cle's fluids (i.e. engine oil, transmission, axle, etc.) for signs
of contamination (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 contami-
nated, as this may result in further damage. Such damage is
not covered by the new vehicle limited warranty.
²Getting water inside your vehicle's engine can cause it to
lockup and stall out and cause serious internal damage to
the engine. Such damage is not covered by the new vehicle
limited warranty.
