Driving your vehicle
Manual transaxle operationThe manual transaxle has 6 forward
gears.
This shift pattern is imprinted on the shift
knob. The transaxle is fully synchronized
in all forward gears so shifting to either a
higher or a lower gear is easily accom-
plished.
To shift gears, press the clutch pedal
down fully, select the desired gear with
the gearshift lever, and release the clutch
pedal slowly.
If your vehicle is equipped with an igni-
tion lock switch, the engine will not start
when starting the engine without
depressing the clutch pedal.
The shift lever must be returned to the
neutral position before shifting into R
(Reverse). The ring (1) located below the
shift knob must be pulled upward while
moving the shift lever to the R (Reverse)
position.Make sure the vehicle is completelystopped before shifting into R (Reverse).
Never operate the engine with thetachometer (rpm) in the red zone.
MANUAL TRANSAXLE (IF EQUIPPED)
OYF059005
The shift lever can be moved into any of
the forward gears without pulling the
ring (1).The ring (1) must be pulled while mov-
ing the shift lever into reverse.
CAUTION
 When downshifting from fifth gear to fourth gear, cautionshould be taken not to inadver- tently press the shift lever side-ways in such a manner that thesecond gear is engaged. Such a drastic downshift may cause theengine speed to increase to the point that the tachometer willenter the red-zone. Such over-revving of the engine and transaxle may possibly causeengine damage.
 Do not downshift more than 2 gears or downshift the gear whenthe engine is running at highspeed (5,000 RPM or higher). Such a downshifting may damagethe engine.

5 During cold weather, shifting may be
difficult until the transaxle lubricant is
warmed up. This is normal and not
harmful to the transaxle.
 If you've come to a complete stop and it's hard to shift into 1st or R (Reverse),
leave the shift lever in the neutral posi-
tion and release the clutch. Depress
the clutch pedal back down, and then
shift into 1st or R (Reverse) gear posi-
tion.
Using the clutchThe clutch should be depressed all the
way to the floor before shifting, then
released slowly. The clutch pedal should
always be fully released while driving. Do
not rest your foot on the clutch pedal
while driving. This can cause unneces-
sary wear. Do not partially engage the
clutch to hold the vehicle on an incline.
This causes unnecessary wear. Use the
foot brake or parking brake to hold the
vehicle on an incline. Do not operate the
clutch pedal rapidly and repeatedly.DownshiftingIt is important to downshift when you
must slow down in heavy traffic or while
driving up or down steep hills.
Downshifting reduces the chance of
stalling and gives better acceleration.
When the vehicle is traveling down steep
hills, downshifting helps maintain safe
speed and prolongs brake life.
WARNING
 Before leaving the driver’s seat,always set the parking brake fully
and shut the engine off. Then
make sure the transaxle is shifted
into 1st gear when the vehicle is
parked on a level or uphill grade,
and shifted into R (Reverse) on a
downhill grade. Unexpected and
sudden vehicle movement can
occur if these precautions are not
followed in the order identified.
CAUTION
 To avoid premature clutch wear and damage, do not drive withyour foot resting on the clutch pedal. Also, don’t use the clutchto hold the vehicle stopped on anuphill grade, while waiting for a traffic light, etc.
 Do not use the shift lever as a handrest during driving, as thiscan result in premature wear ofthe transaxle shift forks.
 When operating the clutch pedal, press the clutch pedal down fully.
If you don't press the clutch pedalfully, the clutch may be damagedor noise may occur.

Driving your vehicle
Good driving practices Never take the vehicle out of gear andcoast down a hill. This is extremely
hazardous. Always leave the vehicle in
gear.
 Do not "ride" the brakes. This can cause them to overheat and malfunc-
tion. Instead, when you are driving
down a long hill, shift to a lower gear.
When you do this, engine braking will
help slow down the vehicle.
 Slow down before shifting to a lower gear. This will help avoid over-revving
the engine, which can cause damage.
 Slow down when you encounter cross winds. This gives you much better con-
trol of your vehicle.
 Be sure the vehicle is completely stopped before you attempt to shift into
R (Reverse). The transaxle can be
damaged if you do not. To shift into R
(Reverse), depress the clutch, move
the shift lever to neutral, wait three sec-
onds, then shift to the R (Reverse)
position.
 Exercise extreme caution when driving on a slippery surface. Be especially
careful when braking, accelerating or
shifting gears. On a slippery surface,
an abrupt change in vehicle speed can
cause the drive wheels to lose traction
and the vehicle to go out of control.
WARNING
 Always buckle-up! In a collision,
an unbelted occupant is signifi-
cantly more likely to be seriously
injured or killed than a properly
belted occupant.
 Avoid high speeds when corner- ing or turning.
 Do not make quick steering wheel movements, such as sharp
lane changes or fast, sharp turns.
 The risk of rollover is greatly increased if you lose control of
your vehicle at highway speeds.
 Loss of control often occurs if two or more wheels drop off the
roadway and the driver over-
steers to reenter the roadway.
 In the event your vehicle leaves the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
 Never exceed posted speed lim- its.
