ºSTARTºÐStarter motor on. The key
will return to the ºONº position when
released.
For starting tips, see Part 3.
ºONºÐEngine on and all accessories on.
This is the normal driving position.
ºACCºÐAccessories such as the radio
operate, but the engine is off.
If you leave the key in the ºACCº or
ºLOCKº position and open the driver's
door, a buzzer will remind you to remove
the key.
ºLOCKºÐEngine 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 ºACCº to the ºLOCKº position. On
vehicles with an automatic transmission,
the selector lever must be in the ºPº posi-
tion before pushing the key.
When starting the engine, the key may
seem stuck at the ºLOCKº 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 ºONº
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 ºPº position when the
brake pedal is depressed (with the ignition
switch in ºONº position and the lock re-
lease button depressed).
(a) Normal driving
1. Start the engine as instructed in ºHow to start the engineº in Part 3. The
transmission must be in ºPº or ºNº.
When the front drive control lever is in
ºL4º (low- speed position, four- wheel
drive), the driving pattern selector setting
has no effect on gear shift timing. (See
ºFour- wheel drive systemº in this chapter
for information of the front drive control
lever.) 2. With your foot holding down the brake pedal, shift the selector lever to ºDº.
In ºDº position, the automatic transmission
system will select the most suitable gear
for running conditions such as normal
cruising, hill climbing, hard towing, etc. Always turn the overdrive switch on for
better fuel economy and quieter driving. If
the engine coolant temperature is low or
when the front drive control lever is in
ºL4º (low- speed position, four- wheel
drive), the transmission will not shift into
the overdrive gear even with the overdrive
switch on. (See ºFour- wheel drive systemº
in this chapter for information of the front
drive control lever.)
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.
(b) Using engine braking
To use engine braking, you can downshift
the transmission as follows: Turn off the overdrive switch. The ºO/D
OFFº indicator light will come on and
the transmission will downshift to the
third gear.
Shift into the º2º position. The trans-
mission will downshift to the second
gear when the vehicle speed drops
down to or lower than the following
speed, and more powerful engine brak-
ing will be obtained.

mission will downshift to the first gear
when the vehicle speed drops down to
or lower than the following speed, and
maximum engine braking will be ap-
plied.

Vehicles with cruise control±When the
cruise control is being used, even if you
downshift the transmission by turning off
the overdrive switch, engine braking will
not be applied because the cruise control
is not cancelled. For ways to decrease
the vehicle speed, see ºCruise controlº in
this chapter.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(c) Using º2º and ºLº positions
The º2º and ºLº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in º2º or ºLº, you
can start the vehicle in motion as with the
lever in ºDº.
With the selector lever in º2º, the vehicle
will start in the first gear and automatical-
ly shift to the second gear.
With the selector lever in ºLº, the trans-
mission is engaged in the first gear.
NOTICE
Be careful not to overrev the en-
gine. Watch the tachometer to keepengine rpm from going into the redzone. The approximate maximum al-
lowable speed for each position isgiven below for your reference:

Do not continue hill climbing for a
long time in the º2º or ºLº posi-
tion. This may cause severe auto-matic transmission damage from overheating. To prevent such dam-
age, use ºDº position for hill climb-ing or hard towing.
(d) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
ºRº position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.

Downshift to the appropriate gear if accel-
eration is needed when you are cruising
below the above downshifting speeds. Upshifting too soon or downshifting too
late will cause lugging, and possibly ping-
ing. Regularly revving the engine to maxi-
mum speed in each gear will cause ex-
cessive engine wear and high fuel
consumption.
Maximum allowable speeds
To get on a highway or to pass slower
traffic, maximum acceleration may be nec-
essary. Make sure you observe the follow-
ing maximum allowable speeds in each

Good driving practice
If it is difficult to shift into reverse, put
the transmission in neutral, release the
clutch pedal momentarily, and then try
again.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use the fifth gear.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
NOTICE
Make sure the vehicle is completely
stopped before shifting into reverse.
Use the front drive control lever to se-
lect the following transfer modes.
ºH2º (high speed position, two- wheel
drive): Lever at ºH2º
Use this for normal driving on dry hard-
surfaced roads. This position gives greater
economy, quietest ride and least wear.
ºH4º (high speed position, four- wheel
drive): Lever at ºH4º
Use this for normal driving on wet, icy or
snow- covered roads. This position pro-
vides greater traction than two- wheel
drive. ºNº (neutral position):
Lever at ºNº
No power is delivered to the wheels. The
vehicle must be stopped.
ºL4º (low speed position, four- wheel
drive): Lever at ºL4º
Use this for maximum power and traction.
Use ºL4º for climbing or descending steep
hills, off- road driving, and hard pulling in
sand, mud or deep snow.
The four- wheel drive indicator light comes
on when the ºH4º, ºNº or ºL4º mode is
selected.
See º(d) Shifting procedure (lever type)º
for further instructions.

See º(d) Shifting procedure (lever/button
type)º for further instructions. (b) Free- wheeling hubsTo engage the free- wheeling hubs, turn
the hubs to ºLOCKº. To disengage, turn
the hubs to ºFREEº.
Make sure the triangle mark on the hub
aligns with the other one at the side you
wish to set.
Setting the free- wheeling hubs in ºFREEº
allows you to disengage the front axle and
driveshaft so that they are not revolving.
This reduces noise and wear when the
vehicle is in two- wheel drive.
You should drive with the hubs in ºLOCKº
for at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated.

You should drive in four- wheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated.
SHIFTING BETWEEN ºH2º AND ºH4º
With free- wheeling hubs
To shift from ºH2º to ºH4º,
move the
front drive control lever. Also, engage both
the free- wheeling hubs.
This can be done when the vehicle is
stopped, or moving straight ahead at
speeds of 40 km/h (25 mph) or less. You
need not depress the clutch pedal. If you
have trouble shifting, depress or release
the accelerator pedal momentarily while
pushing the front drive control lever.
CAUTION
Never move the front drive control
lever if wheels are slipping. Stop
the slipping or spinning before
shifting.
Never drive with only one hub en-gaged.
To shift from ºH4º to ºH2º, simply move
the front drive control lever. Also, disen-
gage both the free- wheeling hubs for con-
tinued ºH2º use.
This can be done at any vehicle speed.
You need not depress the clutch pedal.
