SYSTEM MALFUNCTION
If the low tire pressure warning light
blinks, it indicates a system malfunc-
tion. Contact your Toyota dealer.
The system will be disabled in the condi-
tions below:
Electric devices or facilities using simi-
lar radio wave frequencies are nearby.
If a radio set at similar frequencies is
in use.
Much snowflakes or ice gets on the
vehicle, in particular, around the wheels
or wheel housings.
Non−genuine Toyota wheels are used.
Snow tires or tire chains are used.
The sensor battery is expired.
The tires not equipped with tire pres-
sure sensor are used.
Radio waves from the air pressure sen-
sor installed on the spare tire cannot
be received.
Although the tires are equipped with
tire pressure sensors, the selector
switch (see page 154) is set to other
tire setting.
NOTICE
 The use of nongenuine wheels will
cause the tire pressure sensors to
transmit the electronic code in dif-
ferent manner, resulting in the fail-
ure of the system.
 The use of tires other than origi-
nally installed with genuine wheels
may also cause the malfunction of
the system.

TIRE PRESSURE WARNING SYSTEM RE-
SET SWITCH
The tire pressure warning system needs
to be initialized in the following condi-
tions:
After changing the set pressure
along with the change of the loading
condition or vehicle speed condition
After replacing the ECU
After replacing or tires or wheels
After replacing the tire pressure sen-
sor
When initializing the system, the pres-
ent tire condition is stored as a stan-
dard. To initialize the system, perform the fol-
lowing:
1. Park the vehicle at a safe place and apply the parking brake. Stop the en-
gine.
2. Adjust the pressure of all the installed tires to the specified level. (See
“Tires” on page 344.)
3. Start the engine.
4. Push and hold the reset switch until the low tire pressure warning light
blinks three times.
Do not turn the engine off for about 20
minutes until initialization is complete.
16C522a
When initializing the system, make sure
the low tire pressure warning light blinks
three times. If the warning light does not
blink three times, initialization failed and
the tire pressure warning system will not
function properly. In this case, initialize
the system again.
Do not push the reset switch without ad-
justing the tire inflation pressure to the
specified level. Otherwise, the low tire
pressure warning light may not come on
even if the tire inflation pressure is low,
or it may come on when the tire inflation
pressure is actually normal.
If you push the reset switch while the
vehicle is moving, initialization is not per-
formed.

154
If the low tire pressure warning light does
not blink when you push and hold the
reset switch, have the tire pressure warn-
ing system checked at your Toyota dealer.
NOTICE
Do not turn the engine switch off
during initialization, or the system
may not function properly due to
incomplete initialization.
 Check which tires are being used
before initialization of the system,
and also check the selector switch
position. (See the following “Selec-
tor switch”.)
—Selector switch
16C524a
1. Main position
2. 2nd position
The selector switch is located in the
glove box.
The ID code is given in the tire pres-
sure sensor. To activate the tire pres-
sure warning system, it is necessary to
register the ID code of the sensor on
the selector switch in the vehicle.
2 sets of ID codes can be registered.
The code of the tires originally installed
on the vehicle is registered on the switch
at “MAIN”. Have a new tires set with
new tire pressure sensors registered at
“2nd” by Toyota dealer. ID codes should be registered by Toyota
dealer. Once registered, change the set-
ting position each time you purchase tires
and wheels. Re
−registration is not re-
quired.
When purchasing new tires, consult your
Toyota dealer.
CAUTION
When the tires whose ID code is
registered at “MAIN” are used, the
system does not work properly with
the selector switch set at “2nd”. If
the tires whose ID code is registered
at “2nd” are stored nearby, the sys-
tem will detect their tire inflation
pressure (and vice versa).

157
If you need acceleration—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:a. Pulling the control lever in the “CANCEL” direction and releasing it.
b. Depressing the brake pedal. c. Pushing the “ON −OFF” switch.
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto-
matically cancel out.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will also automatically cancel out.
If the preset speed automatically cancels
out for other than the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity. 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
control lever down in the “– SET” direc-
tion.
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
control lever down in the “– SET” direc-
tion.
Even if you downshift the transmission
from the “D” position to “4” with the cruise
control on, engine braking will not be ap-
plied 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.RESUMING THE PRESET SPEED
If the preset speed is cancelled by pulling
the control lever or by depressing the
brake pedal, pushing the lever up in the
“+ RES” direction will restore the speed
set prior to cancellation.
If the preset speed is cancelled when ve-
hicle speed falls below about 40 km/h (25
mph), the preset speed will be resumed
when vehicle speed exceeds about 40
km/h (25 mph) again.
CRUISE CONTROL FAILURE WARNING
If the “CRUISE” indicator light in the
instrument cluster flashes when using the
cruise control, press the “ON
−OFF” switch
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
control system.
The indicator light does not come on.
The indicator light flashes again.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyota
dealer and have your vehicle inspected.

(g) Operation in cold weather
The active height control suspension
does not operate in cold weather when
the suspension fluid temperature drops
below –30C (–22 F).
In this case, operating the height control
switch does not change the vehicle height.
The vehicle height control enters the
ready mode and the selected height con-
trol indicator light blinks. The active height
control becomes operable if the engine is
warmed up with the suspension fluid tem-
perature being raised within normal operat-
ing limits. The vehicle changes to the se-
lected height when the vehicle height
control is in the ready mode.
When the suspension fluid temperature is
around –30 C (–22 F), the vehicle height
cannot be raised even within the available
load capacity. After warming up the en-
gine, push the control switch on the “
”
side once and then on the “
” side to
select the desired vehicle height.
It takes longer to change the vehicle
height when the suspension fluid tem-
perature drops below –15 C (5 F). (h) 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. (i) Installing or removing h
eavy equip-
ment
If you install or remove heavy equipment
exceeding 15 kg (33 lb.), the front torsion
bar should be adjusted. Consult your To-
yota dealer.
(j) Active height control failure warning
If there is a problem somewhere in the
active height control suspension, the nor-
mal mode is automatically selected. If this
occurs, the height control “OFF” indicator
light blinks and the vehicle height control
cannot be activated until the malfunction
is corrected.
Stop the engine and start it again. If the
height control “OFF” indicator light goes
out, the active height control suspension
returns to normal. If the height control
“OFF” indicator blinks again, bring your
vehicle to your Toyota dealer as soon as
possible and have it checked.

For detailed information on oil level check,
see “Checking the engine oil level” on
page 314.
Your engine is fitted with iridiumtipped
spark plugs.
NOTICE
Use only iridiumtipped spark plugs
and do not adjust gaps for your en-
gine performance and smooth drivabil-
ity.
Brake system
BRAKE SYSTEM
This brake system has two independent
hydraulic circuits. If either circuit should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses brake fluid pres-
surized by the pump to power−assist the
brakes. If the brake booster fails during
driving, the brake system warning light
comes on and buzzer sound continuously.
In this case, the brakes may not work
properly. If they do not work well, depress
the brake pedal firmly. If the brake system
warning light comes on, immediately stop
your vehicle and contact your Toyota deal-
er.
Iridiumtipped spark plugs

232
The brake system warning light may stay
on for about 60 seconds after the ignition
key is turned to “ON” position. It is nor-
mal if the light turns off after a while.
Depressing the brake pedal repeatedly
may turn on the brake system warning
light and buzzer. It is normal if the light
turns off and the buzzer stops sounding
after a few seconds.
You may hear a small sound in the engine
compartment after the engine is started or
the brake pedal is depressed repeatedly.
This is a pump pulsating sound of the
brake system, and it is not a malfunction.
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your brake fluid
pressure reserve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
increase.
ANTILOCK BRAKE SYSTEM
(with “ABS” warning light)
The antilock brake system is designed
to automatically help prevent lockup of
the wheels during a sudden braking or
braking on slippery road surfaces. This
assists in providing 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 perfor-
mance.
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 antilock 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 body
and steering wheel. You may also hear
the motor sound in the engine compart-
ment even after the vehicle is stopped.
At the end of the anti −lock brake sys-
tem activation, the brake pedal may
move a little forward.

233
CAUTION
Do not overestimate the antilock
brake system: Although the antilock
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 antilock brake system does not
provide vehicle control.
Antilock 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
antilock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
Driving on rough, gravel or snow
covered roads.
Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The antilock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed,
resulting in a longer stopping dis-
tance.
“ABS” warning light
The light comes on when the ignition
key is turned to the “ON” position. If
the antilock brake system and the
brake assist system work properly, the
light turns off after a few seconds.
Thereafter, if either of the systems mal-
functions, the light comes on.
