“START”—Starter motor on. The key
will return to the “ON” position when
released.
For starting tips, see Section 3.
“ON”—Engine on and all accessories
on.
This is the normal driving position.
“ACC”—Accessories such as the radio
operate, but the engine is off.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s
door, a buzzer will remind you to remove
the key. “LOCK”—Engine is off and the steering
wheel is locked. The key can be re-
moved only at this position.
You must push in the key to turn the key
from “ACC” to the “LOCK” position. On
vehicles with an automatic transmission,
the selector lever must be in the “P” posi-
tion before pushing the key.
When starting the engine, the key may
seem stuck at the “LOCK” position. To
free it, first be sure the key is pushed all
the way in, and then rock the steering
wheel slightly while turning the key gently.CAUTION
For manual transmission:
Never remove the key when the ve-
hicle is moving, as this will lock the
steering wheel and result in loss of
steering control.
NOTICE
Do not leave the key in the “ON”
position if the engine is not running.
The battery will discharge and the
ignition could be damaged.

Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of “P” position when the
brake pedal is depressed (with the ignition
switch in “ON” or “ACC” position and the
selector lever pulled toward you).

(b) Overdrive switch
You can select either third gear (with
overdrive off) or fourth gear (with over-
drive on) by pushing this switch.
To turn the overdrive off, push the switch.
The “O/D OFF” indicator light should come
on. To turn the overdrive on again, push
the switch again. The “O/D OFF” indicator
light should go off.
Always drive your vehicle with the over-
drive on for better fuel economy and
quieter driving.
If the engine is turned off when the over-
drive is off and restarted, the overdrive
will automatically be on. Vehicles with cruise control—When the
cruise control is being used, even if you
downshift the transmission by pushing and
releasing the overdrive switch, engine
braking will not be enabled because the
cruise control is not cancelled.
For ways to decrease the vehicle speed,
see “Cruise control” in this Section.
(c) Normal driving
1. Start the engine as instructed in “How to start the engine” in Section 3. The
transmission must be in “P” or “N”.
2. With your foot holding down the brake pedal, shift the selector lever to “D”.
When the lever is in the “D” position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc.
Always turn the overdrive on for better
fuel economy and quieter driving. If the
engine coolant temperature is low, the
transmission will not shift into the over-
drive gear even with the overdrive on.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake pedal. Depress the accelerator pedal
slowly for smooth starting.
(d) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Push the overdrive switch. The “O/D
OFF” indicator light will come on and
the transmission will downshift to third
gear.
Shift into the “2” position. The trans-
mission will downshift to second gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled.

Use the front drive control lever to se-
lect the following transfer modes.
“H2” (high speed position, twowheel
drive): Lever at “H2”
Use this for normal driving on dry, hard −
surfaced roads. This position gives greater
economy, the quietest ride and least wear.
“H4” (high speed position, fourwheel
drive): Lever at “H4”
Use this for normal driving on wet, icy or
snow −covered roads. This position pro-
vides greater traction than two− wheel
drive. “N” (neutral position): Lever at “N”
No power is delivered to the wheels. The
vehicle must be stopped.
“L4” (low speed position, fourwheel
drive):
Lever at “L4”
Use this for maximum power and traction.
Use “L4” for climbing or descending steep
hills, off −road driving, and hard pulling in
sand, mud or deep snow.
The “4WD” (four −wheel drive) indicator
light comes on when the “H4”, “N” or “L4”
mode is selected.
See “(c) Shifting procedure (lever type)”
for further instructions.
Advice for driving on slippery roads in
“L4” (low speed position, four wheel
drive) mode
If you shift the front drive control lever to
“L4” and the automatic transmission lever
to “2” when you drive in steep off −road
areas, the output of the brake can be
controlled effectively by the traction con-
trol system, which assists the driver to
control the driving power of 4 wheels. Use the “L” position of the automatic
transmission lever for maximum power
and traction when your wheels get stuck
or when you drive down a steep incline.
In the following cases, the output of the
brake can be controlled by the traction
control system if the engine speed is un-
der 3000 rpm (normally engine speed is
under 3000 rpm when the wheels get un-
stuck).

Drive straight ahead while accelerating or
decelerating, or drive forward or backward
in a short distance. The traction control system automatical-
ly helps prevent the spinning of rear
wheels (twowheel drive models) or 4
wheels (fourwheel drive models) when
the vehicle is started or accelerated on
slippery road surfaces.
When the ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power to the rear wheels (twowheel
drive models) or 4 wheels (fourwheel
drive models) cannot be maintained,
even though the traction control sys-
tem is in operation. Do not drive the
vehicle under any speed or maneuver-
ing conditions which may cause the
vehicle to lose traction control. In si-
tuations where the road surface is
covered with ice or snow, your ve-
hicle should be fitted with snow tires
or tire chains. Always drive at an ap-
propriate and cautious speed for the
present road conditions.
