IGNITION SWITCH AND
ANTITHEFT STEERING
COLUMN LOCK IGNITION SWITCH POSITIONLOCKThe steering wheel is locked to protect
against theft. The ignition key can be
removed only in the LOCK position. For
vehicles equipped with an automatic
transaxle, it also locks the gear shift lever
in the P (Park) position.
ACC (ACCESSORY)Turning the ignition switch to this
position unlocks the steering wheel and
will allow some of your vehicle’s
electrical accessories such as the radio to
operate when the engine is OFF.ONTurning the ignition switch to this
position allows you to test your vehicle’s
warning lights (except the brake system
warning light) to make sure they work
before you start the engine. The ignition
key returns to the ON position once the
engine is started and remains in this
position while the engine is running.
Do not leave the ignition switch in the
ON position for extended periods with
the engine OFF because the battery will
discharge.

NORMAL OPERATIONP (Park)This position locks the transaxle and
prevents the front wheels from rotating.
Always come to a complete stop before
shifting into this position.
R (Reverse)Use this position to drive the vehicle
backward.N (Neutral)In this position, the wheels and transaxle
are not locked. The vehicle will roll
freely even on the slightest incline unless
the parking brake or service brakes are
applied.D (Drive)This is the normal forward driving
position. The transaxle will auto-
matically shift through a four-gear
sequence, providing the best fuel
economy and power.
4-9
WARNING
Shifting into P (Park) while the
vehicle is in motion will cause
the front wheels to lock and you
will lose driving control of the
vehicle.✻
NOTICE
The transaxle may be damaged if
you shift into P (Park) while the
vehicle is in motion.
WARNING
Do not use the P (Park)
position in place of the

NOTICE
• In sports mode, only the four
forward gears can be selected.
To reverse or park the vehicle,
move the shift lever to the “R”
or “P” position as required.
• In sports mode, downward shifts
are made automatically when the
vehicle slows down. When the
vehicle stops, 1st gear is automati-
cally selected.
• In sports mode, shift points are
varied to upward shifts automat-
ically when the engine rpm
approaches red zone.
• To maintain the required levels
of vehicle performance and safe-
ty, the system may not execute
certain gear shifts when the shift
lever is operated.
• When driving on a slippery road,
push the shift lever forward into
the +(Up) position. This causes
the transaxle to shift into the 2nd
gear which is better for smooth
driving on a slippery road. Push
the shift lever to the -(Down) side
to shift back to the 1st gear.
✻
NOTICE
• For smooth and safe operation,
depress the brake pedal when
shifting from “Neutral” position or
“Park” position to a forward or
reverse gear.
• The ignition key must be in the
“ON” position and the brake
pedal fully depressed in order to
move the shift lever from the
“P”(Park) position to any of the
other positions.
• It is always possible to shift from
“R”, “N”, “D” position to the
“P” position. But before shifting
to “P” make sure the vehicle is
fully stopped to avoid transaxle
damage.
