CAUTION
Never attempt to move the selector
lever into “P” position under any cir-
cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.
(h) Good driving practice
If the transmission repeatedly shifts up
and down between third gear and over-
drive when climbing a gentle slope, the
overdrive should be turned off. Be sure
to turn the switch on immediately after-
ward.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.
CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
NOTICE
Always use the brake pedal or the
parking brake to hold the vehicle on
an upgrade. Do not attempt to hold
the vehicle using the accelerator ped-
al, as this can cause the transmission
to overheat.
The shift pattern is as shown above.
Press the clutch pedal down fully while
shifting, and then release it slowly. Do not
rest your foot on the pedal while driving,
because it will cause clutch trouble. And
do not use the clutch to hold the vehicle
when stopped on an uphill grade—use the
parking brake.

Recommended shifting speeds
The transmission is fully synchronized and
upshifting or downshifting is easy.
For the best compromise between fuel
economy and vehicle performance, you
should upshift or downshift at the following
speeds:
gear km/h (mph)
1 to 2 or 2 to 1 24 (15)
2 to 3 or 3 to 2 40 (25)
3 to 4 or 4 to 3 64 (40)
4 to 5 or 5 to 4 72 (45)
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
gear:
Tw o
−wheel drive models
gear km/h (mph)
1 45 (28)
2 85 (53)
3 125 (78)
4 165 (112)
Four −wheel drive models
gear km/h (mph)
“H2” or “H4” “L4”
1 45 (28) 15 (9)
2 85 (53) 30 (18)
3 125 (78) 45 (28)
4 165 (103) 70 (43)
NOTICE
Do not downshift if you are going
faster than the maximum allowable
speed for the next lower gear.
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 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.
“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).

2. “4HI” (high speed position, four wheel drive): “2WD/4HI” button pushed
in
The “4HI” (high speed four −wheel
drive) indicator light comes on when
the “4HI” mode is selected.
Use this for normal driving on wet, icy
or snow −covered roads. This position
provides greater traction than two −
wheel drive.
In this mode, the vehicle stability con-
trol system is off. (See “Vehicle stabil-
ity control system” in this Section.) 3. “4LO” (low speed position, four
wheel drive): With the “2WD/4HI”
button pressed in, push the “4LO”
button
The “4LO” (low speed four −wheel drive)
indicator light comes on when the
“4LO” mode is selected.
Use this for maximum power and trac-
tion. Use “4LO” mode for climbing or
descending steep hills, off −road driving,
and hard pulling in s and, mud or deep
snow.
In this mode, the vehicle stability con-
trol system is off. (See “Vehicle stabil-
ity control system” in this Section.)
See “(c) Shifting procedure (button type)”

Advice for driving on slippery roads in
“4LO” (low speed position, four wheel
drive) mode
If you push the “4LO” button with the
“2WD/4HI” button pressed in and shift the
automatic transmission lever to “2” when
you drive in steep off −road areas, the out-
put of the brake can be controlled effec-
tively by the traction control system,
which assists the driver to control the
driving power of 4 wheels.

gaged by the shifting operations de-
scribed in “(c) Shifting procedure”.
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 “H2” AND “H4”
To shift from “H2” to “H4”,
reduce the
vehicle speed to less than 80 km/h (50
mph) and move the front drive control
lever. If the indicator light does not come
on when you shift the transfer into “H4”,
drive straight ahead while accelerating or
decelerating, or drive forward or backward
in a short distance. You need not depress
the clutch pedal.
If you have trouble shifting in cold weath-
er, reduce the vehicle speed or stop the
vehicle and reshift.
CAUTION
Never move the front drive control
lever if wheels are slipping. Stop the
slipping or spinning before shifting.
To shift from “H4” to “H2”, simply move
the front drive control lever.
This can be done at any speed. You need
not depress the clutch pedal.

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.
