Keep in mind the following when driv-
ing.
The hill−start assist control system op-
erates for 5 seconds maximally. If both
the brake and accelerator pedals re-
main undepressed for longer than 5
seconds, the buzzer will sound at more
frequent intervals and the system will
gradually stop operating.
The hill−start assist control system is
not designed as a function for stopping
the vehicle on a uphill slope. When
stopping the vehicle, be sure to de-
press the brake pedal.
The brake actuator temperature increases
during continuous operation of the downhill
assist control system (four−wheel drive
models), the traction control system (two−
wheel drive models), the active traction
control system (four−wheel drive models),
the vehicle stability control system and
the AUTO LSD" system (two−wheel drive
models) on such as slippery 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 hill−start assist
control system can no longer operate. In
this case, stop your vehicle immediately 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.)
At this time, the slip indicator light will
come on and the hill−start assist control
system stops operating temporarily in or-
der to protect the brake actuator. (Al-
though the h
ill−start assist control system
does not operate, it is no problem to con-
tinue your driving.) The system will be
automatically restored after a short time
and the slip indicator light goes out.

This rear height control air suspension
controls the vehicle height depending
on the vehicle driving conditions. Select
your desired height among the HI"
(high), N" (normal) and LO" (low)
modes with the height select switch.
(a) Vehicle height modes
N" (normal) mode
The vehicle height in this mode is stan-
dard. Regardless of the number of occu-
pants or the luggage loading condition, the
vehicle height is always automatically ad-
justed to a fixed height in this mode while
the engine is running.
This mode is suitable for ordinary driving. HI" (high) mode
The vehicle height is about 40 mm (1.6
in.) higher at rear than the N" mode
height.
This mode is suitable when driving on the
bumpy roads and through water.
However, when the vehicle speed exceeds
about 30 km/h (19 mph) or over in the
HI" mode, the N" mode is automatically
selected.
CAUTION
The HI" mode should be used for
severe off−road driving condition
only. Because the vehicle’s center of
gravity is higher in this setting, the
vehicle may become unstable when
turning abruptly, resulting in accident.

light blinks.
2. The selected mode indicator light goes off. (The vehicle height does not
change.) The present mode indicator
light comes on again.
In this case, even if the vehicle is moved
to its usual location or the ice is removed
and the height select switch is pressed,
vehicle height control cannot be operated.
Turn off the engine once and then restart
it.
Height control OFF" indicator light:

light comes on. If it goes out after a few
seconds, the rear height control air sus-
pension operates correctly. If you push the
HEIGHT CONTROL OFF" switch, the rear
height control air suspension is turned off.
The height control OFF" indicator light
comes on.
In the following cases, there is a problem
somewhere in the rear height control air
suspension. Although there is no problem
to continue normal driving, have the rear
height control air suspension checked by
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 tire pressure warning light comes on
when the engine switch is in ON" position
and goes off after a few seconds. This
means the tire pressure warning system is
operating properly. If the tire inflation pres-
sure becomes low, the light comes on
again. In this case, adjusting the tire infla-
tion pressure will turn off the light after a
few minutes. If the light comes on after
blinking for 1 minute, the tire pressure
warning system is not working properly.Indicatorstatus

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 waring 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 spare tire and have the flat tire
repaired by the nearest Toyota deal-
er.
Avoid abrupt maneuvering and brak-
ing. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.
The tire pressure warning light may turn
on due to natural causes such as natural
air leaks or tire inflation pressure changes
caused by temperature. In this case, ad-
justing the tire inflation pressure will turn
off the light after a few minutes.
The spare tire is also equipped with the
tire pressure warning valve and transmit-
ter. The tire pressure waning light will turn
on if the tire inflation pressure of the
spare tire is low. If a tire goes flat, even
though the flat tire is replaced with the
spare tire, the warning light does not turn
off. Replace the spare tire with the re-
paired tire and adjust the proper tire infla-
tion pressure. The tire pressure warning
light will turn off after a few minutes.CAUTION
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label (tire
and load information label). (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label
(tire and load information label), you
should determine the proper tire infla-
tion pressure for those tires.)
