The vehicle stability control system au-
tomatically turns off, and the “VSC
OFF” indicator light is illuminated,
when the fourwheel drive mode is set.

When getting the vehicle out of mud or
newly fallen snow, etc., it may be bene-
ficial to turn off the vehicle stability
control system. This system which also
controls engine performance interferes
with the process of freeing the rear
wheels (twowheel drive models).
To turn off the vehicle stability control
system: Push and hold the “VSC OFF”
switch for 3 seconds or more with the
vehicle stopped. The vehicle stability
control system turns off and the “AUTO
LSD” mode turns on.
The “AUTO LSD”, slip indicator and “VSC
OFF” lights will come on. When you push and hold the “VSC OFF”
switch for 3 seconds or more with the
vehicle stopped, the “AUTO LSD” mode
turns off and the “VSC OFF” mode turns
on.
After the indicator light turns off, the “VSC
OFF” and slip indicator lights will come
on.
“VSC OFF” mode can turn off the fol-
lowing systems:
Vehicle stability control system
Traction control system
“AUTO LSD” system (two
−wheel drive
mode)
Active traction control system (four −
wheel drive mode)
To turn on: Briefly push the “VSC OFF”
switch once again.
The “VSC OFF” and slip indicator lights
will go off.
If the engine is turned off while the “VSC
OFF” and slip indicator lights are on and
then restarted, the indicator lights will turn
off automatically.

The “VSC OFF” indicator light flashes
and the slip indicator light comes on
The “VSC OFF” indicator light flashes and
the slip indicator light comes on to warn
that there is a problem somewhere in the
following:
Vehicle stability control system
Traction control system
“AUTO LSD” system
The slight comes on when the engine
switch is turned to the “ON” position, and
will go off after a few seconds.
If the “VSC OFF” indicator light flashes
and the slip indicator light comes on dur-
ing driving, the vehicle stability control
system will not work. However, if the
brakes operate normally when applied, it
is not a problem to continue driving.
In the following cases, contact your Toyota
dealer:
The “VSC OFF” and slip indicator lights
do not come on after the engine switch
is turned to the “ON” position.
The “VSC OFF” indicator light flashes
and the slip indicator light remains on
after the engine switch is turned to the
“ON” position.
The “VSC OFF” indicator light flashes
and the slip indicator light comes on
while driving. The tire pressure warning system warns
you that the tire inflation pressure is
low.
The tire pressure warning system is not
a substitute for checking normal tire infla-
tion pressure. Check the tire inflation
pressure with a tire pressure gauge regu-
larly.
CAUTION
The warning system may not activate
immediately if blowout or sudden air
loss should occur.

The tire pressure warning light comes on
when the engine switch is turned to the
“ON” position and goes off after a few
seconds. This means the tire pressure
warning system is operating properly. If
the tire inflation pressure becomes low,
the light comes on again. In this case,
adjusting the tire inflation pressure will
turn off the light after several minutes. If
the light comes on after blinking for 1
minute, the tire pressure warning system
is not working properly.

CAUTION
If the tire pressure warning light
comes on, be sure to observe the
following precautions. Failure to do
so could cause loss of vehicle control
and result in death or serious injury.
Stop your vehicle in a safe place as
soon as possible. Adjust the tire
inflation pressure immediately.
If the tire pressure warning light
comes on even after tire inflation
pressure adjustment, it is probable
that you have a flat tire. Check the
tires. If the tire is flat, change to
the temporary spare tire and have
the flat tire repaired by the nearest
Toyota dealer.
Avoid abrupt maneuvering and brak-
ing. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.

IF THE TIRE PRESSURE WARNING
LIGHT COMES ON AFTER BLINKING
FOR 1 MINUTE...
If the tire pressure warning light comes
on after blinking for 1 minute when the
engine switch is turned to the “ON”
position, the tire pressure warning sys-
tem is not working properly.
The system will be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work properly.)
If tires not equipped with tire pressure
warning valves and transmitters are
used.
If the ID code on the tire pressure
warning valves and transmitters is not
registered in the tire pressure warning
computer.
The system may be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work properly.)
If electronic devices or facilities using
similar radio wave frequencies are
nearby.
If a radio set at similar frequencies is
in use in the vehicle.
If a window tint that affects the radio
wave signals is installed.
If there is a lot of snow or ice on the
vehicle, in particular around the wheels
or wheel housings.
If non −genuine Toyota wheels are used.
If tire chains are used.
If the tire pressure warning light continues
to come on after blinking for 1 minute
when the engine switch is turned to the
“ON” position, have the system checked
by your Toyota dealer.
Even if you use genuine wheels, the tire
pressure warning system may not work
properly with some types of tires.
Pushing the tire pressure warning reset
switch should not turn off the tire pressure
warning light.

TIRE PRESSURE WARNING RESET
SWITCH
When initializing the system, the present
tire inflation pressure is stored as stan-
dard. The tire pressure warning system
determines decreased air pressure by
comparing the present and the standard
tire inflation pressures. When you change
the set tire inflation pressure, it is neces-
sary to initialize the tire pressure warning
system.
When rotating the tires on vehicles dif-
fering with front and rear tire inflation
pressures.
When changing the tire inflation pres-
sure according to the instruction for
traveling speed, load weight or tire
size.
To initialize the system, perform the
following:
1. Park the vehicle in a safe place and turn the engine switch to the “ACC” or
“LOCK” position.
2. Adjust the pressure of all the installed tires to the specified cold tire inflation
pressure level. (See “Tires” on page
594 in Section 8.)
3. Turn the engine switch to the “ON” position.
4. Push and hold the tire pressure warn- ing reset switch until the tire pressure
warning light blinks slowly three times.
5. Wait for several minutes with the engi- ne switch “ON”, and then turn the engi-
ne switch to the “ACC” or “LOCK” posi-
tion.
If you push the tire pressure warning re-
set switch while the vehicle is moving,
initialization is not performed. If you push the tire pressure warning re-
set switch accidentally and initialization is
performed, adjust the tire inflation pres-
sure to the specified level and initialize
the system again.

When parking, firmly apply the parking
brake to avoid inadvertent creeping.
To set: Fully depress the parking brake
pedal. For better holding power, first de-
press the brake pedal and hold it while
setting the parking brake.
To release: Depress the parking brake
pedal once again.
To remind you that the parking brake is
set, the parking brake reminder light in
the instrument panel remains on until you
release the parking brake.
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
The cruise control is designed to main-
tain a set cruising speed without requir-
ing the driver to operate the accelera-
tor. Cruising speed can be set to any
speed above 40 km/h (25 mph).
Within the limits of the engine’s capabili-
ties, cruising speed can be maintained up
or down grades. However, changes in ve-
hicle speed may occur on steeper grades.
CAUTION
To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snowcovered) or
winding roads.
Be careful about vehicle speed as
it may increase when driving down-
hill with the cruise control on.

TURNING THE SYSTEM ON AND OFF
To turn the cruise control on, press the
“ON−OFF” button. The “CRUISE” indicator
light on the instrument panel will come on
to indicate that the cruise control is opera-
tional. Pressing the “ON −OFF” button
again turns the system off.
When the system is turned off, cruising
speed must be reset when the cruise con-
trol is turned on again.
When the engine switch is turned off, the
system is also automatically turned off. To
use the cruise control again, press the
“ON −OFF” button again to turn it on.
