The active traction control system auto-
matically helps prevent the spinning of
4 wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the engine switch 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 4 wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.
CY16073
NORMAL DRIVING MODE
Leave the system on during the ordi-
nary driving so that it can operate
when needed.
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the ac-
tive traction control system is in the self−
check mode, but does not indicate a mal-
function.
When the active traction control system is
operating, the following conditions occur:
The system controls the spinning of the
4 wheels. At this time, the slip indica-
tor light blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to ON". If the indicator light does not
come on when the engine switch is turned
on, contact your Toyota dealer.
The brake actuator temperature increases
during continuous operation of the active
traction control system, the vehicle stabil-
ity control system, the downhill assist con-
trol system and the hill−start assist control
system such as on sli ppery roads. If the
brake actuator temperature becomes too
high while any of the systems is operat-
ing, a buzzer will start to sound intermit-
tently to indicate that the active traction
control system can no longer operate. In
this case, immediately stop your vehicle at
a safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.)

The vehicle stability control system
helps provide integrated control of the
systems such as anti−lock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the output of the brakes or engine to
help prevent the vehicle from skidding
when cornering on a slippery road sur-
face or operating steering wheel abrupt-
ly.
The vehicle stability control system is acti-
vated when the vehicle speed is more
than 15 km/h (9 mph).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the sys-
tem is in the self−check mode, but does
not indicate a malfunction.CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the system is operating, it cannot
completely eliminate the possibility
of an accident. Always keep safe
driving in mind, as reckless driving
increases the risk of an accident. If
the slip indicator light blinks, spe-
cial care should be taken while
driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
Checking and replacing tires" on
page 443 in Section 7−2.)
CY16073
If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
If the brake pedal is depressed while the
vehicle stability control system is active,
the brake pedal will become hard at an
earlier position than usual. However, the
brakes will respond to the pedal force if
depressed further.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to ON". If the indicator light does not
come on when the engine switch is turned
on, contact your Toyota dealer.

vehicle height is being lowered, the opera-
tion continues for up to 25 seconds. If,
within this 25 seconds, any of the side
doors or the back door is opened, opera-
tion will continue for a further 15 seconds.
NOTICE
 If the vehicle height is changed fre-
quently when the vehicle is heavily
loaded, the compressor may over-
heat, causing the vehicle height ad-
justment operation to stop.
 Before you lower the vehicle height
with the height select switch, check
under the vehicle to make sure
nothing to damage the vehicle or
no one to be injured is there and
that the underbody of the vehicle
does not touch the ground.
 After unloading, the height of a ve-
hicle equipped with the rear height
control air suspension becomes
slightly higher than the normal ve-
hicle height. Take sufficient care
where the overhead height is re-
stricted.
 Do not select the LO" mode in the
bumpy roads. If the underbody of
the vehicle touches the rugged road
surface, the vehicle may be dam-
aged.

your Toyota dealer as soon as possible.The height control OFF" indicator light
does not come on when the engine
switch is turned on.
The height control OFF" indicator light
blinks.
(f) Parking and stopping tips
If you immediately stop the engine to park
the vehicle after off−road driving, the ve-
hicle height is lowered slightly as the ve-
hicle becomes cool. When parking, make
sure there is nothing that will be in con-
tact with the underbody of the vehicle.
When you start the engine, the vehicle
returns to the previous height.
If you park the vehicle for a long time,
the vehicle height may be gradually low-
ered. When parking for a long time, make
sure there is nothing that will be in con-
tact with the underbody of the vehicle.
When you start the engine, the vehicle
returns to the previous height.
If you stop the engine, the vehicle height
may change in accordance with the
change in the temperature. When you
start the engine, the vehicle returns to the
previous height. (g) Rear height control failure warning
If there is a problem somewhere in the
rear height control air suspension, the N"
mode is automatically selected. If this oc-
curs, the height control OFF" indicator
light blinks and the vehicle height control
cannot be activated until the malfunction
is corrected. If this is the case, bring your
vehicle to your Toyota dealer as soon as
possible and have it checked.

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 CRUISE" indicator light remains on
to indicate that the system is still in op-
eration.
To turn the cruise control off, press the
ON−OFF" button. Make sure the
CRUISE" indicator light is off.
If the cruise control automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESUMING THE CRUISE CONTROL
If the cruise control is temporarily can-
celled, the cruising speed can be resumed
by pushing the lever up in the + RES"
direction.
Vehicle speed must be above 40 km/h (25
mph).
RESETTING TO A FASTER SPEED
Push the lever up in the + RES" direction
and hold it. Release the lever when the
desired speed is attained. While the lever
is held up, the vehicle will gradually gain
speed.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the − SET" direction.RESETTING TO A SLOWER SPEED
Push the lever down in the − SET" direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held down, the vehicle speed will
gradually decrease.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the − SET" direction.
Even if you downshift from D" to 4", with
the cruise control on, engine braking will
not be enabled because the cruise control
is not cancelled. To decrease the vehicle
speed, reset to a slower speed with the
cruise control lever or depress the brake
pedal. If you use the brake pedal, cruise
control is cancelled.
CRUISE CONTROL FAILURE WARNING
If the CRUISE" indicator light flashes
when using the cruise control, press the
ON−OFF" button to turn the system off
and then press it again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise

ANTI−LOCK BRAKE SYSTEM
(with ABS" warning light)
The anti−lock brake system is designed
to help prevent lock−up of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS brake
pedal: When the anti−lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti−lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking performan-
ce.
The anti−lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph). Depressing the brake pedal on slippery
road surfaces such as on a manhole cov-
er, a steel plate at a construction site,
joints in a bridge, etc. on a rainy day
tends to activate the anti−lock brake sys-
tem.
You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle begins to move. This means
that the anti−lock brake system is in the
self−check mode, and does not indicate a
malfunction.
When the anti−lock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You may hear the anti−lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
At the end of the anti−lock brake sys-
tem activation, the brake pedal may
move a little forward.
CAUTION
Do not overestimate the anti−lock
brake system: Although the anti−lock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti−
lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the anti−lock brake system does not
provide vehicle control.
Anti−lock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at a moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
anti−lock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
Driving on rough, gravel or snow−
covered roads.

1. Check the area around the vehicle be-fore entering it.
2. Adjust seat position, seatback angle, seat cushion angle, head restraint
height and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts. Once you turn the engine switch to
START" position and release it, the crank-
ing hold function continues to crank the
engine in ON" position until it starts.
The function stops cranking the engine
after about 25 seconds maximum if the
engine has not started yet. When you
crank the engine again, wait a few sec-
onds and restart it.
If you hold the engine switch in START"
position, the function will keep cranking
for about 30 seconds maximum. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces-
sories.
3. Put the selector lever in P". If you need to restart the engine while the
vehicle is moving, put the selector le-
ver in N". A starter safety device will
prevent the starter from operating if the
selector lever is in any drive position.
4. Depress the brake pedal and hold it to the floor until driving off.
