(f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
(g) ªABSº Warning Light
The light comes on when the ignition key
is turned to the ªONº position. If the anti±
lock brake system and the brake assist
system work properly, the light turns off
after a few seconds. Thereafter, if either
of the systems malfunctions, the light
comes on again.
When the ªABSº warning light is on (and
the brake system warning light is off), the
anti±lock brake system, the brake assist
system, the traction control system (two±
wheel drive vehicles), the active traction
control system (four±wheel drive vehicles)
and the vehicle stability control system do
not operate, but the brake system still
operates conventionally.When the ªABSº warning light is on (and
the brake system warning light is off), the
anti±lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If either of the following conditions
occurs, this indicates a malfunction
somewhere in the components moni-
tored by the warning light system. Con-
tact your Toyota dealer as soon as
possible to service the vehicle.

The light does not come on when the
ignition key is turned to the ªONº posi-
tion, or remains on.

The light comes on while you are dri-
ving.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the ªABSº warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the anti±lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
(h) ªVSC TRACº Warning Light
This light warns that there is a problem
somewhere in the vehicle stability control
system and traction control system (two±
wheel drive models) or active traction con-
trol system (four±wheel drive models).
The light will come on when the ignition
key is turned to ªONº and will go off after
a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.

The warning light comes on while driv-
ing.
(i) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed.
(j) SRS Warning Light
This light will come on when the igni-
tion key is turned to the ªONº position.
After about 6 seconds, the light will go
off. This means the system of the air-
bag and front seat belt pretensioner are
operating properly.This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er 's seat position sensor, driver 's seat belt
buckle switch, front passenger occupant
classification system and indicator light,
front passenger 's seat belt buckle switch,
seat belt pretensioner assemblies, inflat-
ors, warning light, ªRSCA OFFº indicator
light, interconnecting wiring and power
sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.

The light does not come on when the
ignition key is turned to the ªONº posi-
tion or remains on for more than 6
seconds.

The light comes on while driving.(k) Automatic Transmission Fluid Tem-
perature Warning Light (four±wheel
drive models)
This light warns that the automatic trans-
mission fluid temperature is too high.
If this light comes on while you are driv-
ing, slow down and pull off the road. Stop
the vehicle at a safe place and put the
selector lever in ªPº. With the engine id-
ling, wait until the light goes off. If the
light goes off, you may start the vehicle
again. If the light does not go off, call a

(c) Overdrive switch
You can select either fourth gear (with
overdrive off) or fifth gear (with overdrive
on) by pushing this switch.
To turn the overdrive off, push the switch.
The ªO/D OFFº indicator light should come
on. To turn the overdrive on again, push
the switch again. The ªO/D OFFº 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 be on automatically.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 can-
celled.
For ways to decrease the vehicle speed,
see ªCruise controlº on page 205 in this
Section.
(d) Normal driving
1. Start the engine as instructed in ªHow
to start the engineº on page 362 in
Section 3. The transmission must be in
ªPº or ªNº.
When the front drive control is in ª4LOº
mode (low speed, four±wheel drive), the
driving pattern selector setting has no ef-
fect on gear shift timing. (See ªFour±wheel
drive systemº on page 177 in this Section
for information on the front drive control.)
2. With your foot holding down the brake
pedal, shift the selector lever to ªDº.
When the lever is in the ªDº 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.If the engine coolant temperature is low
or when the front drive control is in ª4LOº
mode (low speed, four±wheel drive), the
transmission will not shift into the over-
drive gear even with the overdrive on.
(See ªFour±wheel drive systemº on page
177 in this Section for information of the
front drive control.)
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.
If the automatic locking operation linked to
shift lever position is set, all doors are
automatically locked when the shift lever
is moved out of ªPº position after the
ignition switch is turned to the ªONº posi-
tion and all the doors are closed. For
details, see ªÐAutomatic door locking and
unlocking functionsº on page 27 in Section
1±2.

the transmission as follows:

Push the overdrive switch. The ªO/D
OFFº indicator light will come on and
the transmission will downshift to fourth
gear.

Shift into the ª3º position. The trans-
mission will downshift to third gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled.
Two±wheel drive models
121 km/h (75 mph)
Four±wheel drive models
ª2WDº or ª4HIº mode
121 km/h (75 mph)
ª4LOº mode 47 km/h (29 mph)

Shift into the ª2º 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.
Two±wheel drive models
80 km/h (49 mph)
Four±wheel drive models
ª2WDº or ª4HIº mode
80 km/h (49 mph)
ª4LOº mode 31 km/h (19 mph)

Push the ªSHIFT Lº switch. The trans-
mission will downshift to first gear
when the vehicle speed drops down to
or lower than the following speed, and
maximum engine braking will be en-
abled.

Four±wheel drive models
ª2WDº or ª4HIº mode
35 km/h (21 mph)
ª4LOº mode 13 km/h (8 mph)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 can-
celled.
For ways to decrease the vehicle speed,
see ªCruise controlº on page 205 in this

(f) Using the ª3º, ª2º and ªLº, posi-
tions
The ª3º, ª2º and ªLº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in ª3º, ª2º or
ªSHIFT Lº switch depressed, the vehicle
can start just as if the lever was in ªDº.
With the selector lever in ª3º or ª2º, the
vehicle will start in first gear and automat-
ically shift to second gear.
With the ªSHIFT Lº switch depressed, the
transmission is engaged in first gear.NOTICE

Be careful not to over±rev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given above for your reference:
Two±wheel drive models
ª3º 135 km/h (84 mph). . . . . . .
ª2º 90 km/h (56 mph). . . . . . . .

Do not continue hill climbing or
hard towing for a long time in the
ª3º, ª2º or ªLº position. This may
cause severe automatic transmis-
sion damage from overheating. To
prevent such damage, ªDº position
should be used in hill climbing or
hard towing.
(g) 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
ªRº position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(h) Parking
1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down,
fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down,
shift the selector lever to the ªPº posi-
tion.

If the automatic unlocking operation linked
to shift lever position is set, all doors are
automatically unlocked when the selector
lever is moved to ªPº position after the
ignition switch is turned to ªONº position.
For details, see ªÐAutomatic door locking
and unlocking functionsº on page 27 in
Section 1±2.
(i) Good driving practice

If the transmission repeatedly shifts up
and down between fourth gear and
overdrive when climbing a gentle slope,
the overdrive should be turned off. Be
sure to turn the switch on immediately
afterward.

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.

Use the front drive control switches
and center differential lock switch to
select the transfer and center differen-
tial modes.
In the ª4HIº and ª4LOº mode, you can
choose to lock or unlock the center differ-
ential.
Use the center differential lock system if
your wheels get stuck in a ditch, or when
you are driving on a slippery or bumpy
surface. When the center differential is
locked, the vehicle stability control system
is automatically turned off and the center
differential lock and ªVSC OFFº indicator
lights come on because the function that
controls engine performance interferes
with the process of freeing your wheels.
NOTICE
As soon as the center differential lock
switch is turned on, the ªVSC OFFº
indicator light comes on. After the
wheels are out of the ditch or off the
slippery or bumpy surface, turn the
center differential lock switch off.
Make sure that the center differential
lock indicator light and ªVSC OFFº
indicator light turn off.
ª2WDº mode (high speed, two±wheel
drive)
This mode is the normal driving mode. In
this mode, the ª4HIº and ª4LOº indicator
lights are turned off.
Use this for normal driving on dry hard±
surfaced roads. This position gives greater
economy, quietest ride, least wear and
better vehicle control.
ª4HIº mode (high speed, four±wheel
drive, center differential unlocked)
To select this mode, press the ª2WD/4HIº
switch only. The ª4HIº indicator light
comes on.
Use this for normal driving on all types of
roads, from dry hard±surfaced roads to
wet, icy or snow±covered roads. This
position provides greater traction than
two±wheel drive.ª4HIº mode (high speed, four±wheel
drive, center differential locked)
To select this mode, press the ª2DW/4HIº
switch, and then the center differential
lock switch. The ª4HIº and the center dif-
ferential lock indicator lights come on.
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the center differential
unlock mode.
ª4LOº mode (low speed, four±wheel
drive, center differential unlocked)
To select this mode, press the ª4LOº
switch only. The ª4LOº indicator light
comes on.
Use this for maximum power and traction.
Use this for climbing steep hills, off±road
driving, and hard pulling in sand or mud.
In this mode, the braking feeling that oc-
curs when the wheels are negotiating a
sharp corner is further reduced than in the
ª4LOº (low speed, four±wheel drive, center
differential locked) mode.
