The hillstart assist control system will
operate for 5 seconds maximally when
all of the following conditions apply.
5speed automatic transmission—
When the transmission is in any of
positions “D”, “4”, “3”, “2” or “L”
4speed automatic transmission—
When the transmission is in any of
positions “D”, “3”, “2” or “L”
When the brake pedal is not de-
pressed
The system is designed to operate when
the vehicle is starting on an uphill slope;
therefore, if the transmission is in “P” or
“N” it will not operate. It will not operate
either if the vehicle starts to move in
reverse on a slope with the transmission
in the “R”.
When the hillstart assist control system
is operating, the slip indicator light flashes
and an alarm sounds intermittently. At the
same time, the stop lamps and high
mounted stoplight are lit.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer. Keep in mind the following when driv-
ing.
The hillstart 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 hillstart 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.
If the system is used frequently, the
brake actuator temperature may become
too high and a buzzer will sound inter-
mittently.
In this case, a buzzer will sound intermit-
tently. When the temperature of the brake
actuator goes down, the system will begin
to operate again. Until it restarts, the trac-
tion control system (twowheel drive mod-
els), active traction control system (four
wheel drive models) and downhill assist
control system will not operate; however,
the conventional brake can be operated.

If there is any abnormality in the sys-
tem, the “VSC TRAC” warning light will
come on.
If the system malfunctions, the “VSC
TRAC” warning light will come on.
If the “VSC TRAC” warning light comes
on, there may be an abnormality in any
of the following systems in addition to the
hillstart assist control system.
Downhill assist control system
(fourwheel drive models)
Traction control system
(twowheel drive models)
Active traction control system
(fourwheel drive models)
Vehicle stability control system “VSC TRAC” warning light
When the system is normal and the igni-
tion key is turned to “ON”, the warning
light will come on and will go off after a
few seconds.
It is not a malfunction that the warning
light may stay on for 60 seconds after the
ignition key is turned to “ON”.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes out after a few seconds.
The brake actuator temperature increases
during continuous operation of the above
mentioned system on such as slippery
roads. If the brake actuator temperature
becomes too high while any of the sys-
tems is operating, a buzzer will start to
sound intermittently to indicate that the
hillstart assist control system can no lon-
ger operate. In this case, stop your ve-
hicle 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 “VSC TRAC” warning
light will come on and the hillstart assist
control system stops operating temporarily
in order to protect the brake actuator. (Al-
though the h
illstart 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 “VSC TRAC” warning light goes
out.
If the warning light comes on while driv-
ing, the system does not work. However,
as normal braking operates when being
applied, it is no problem to continue your
driving.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.

(e) Height control indicator lights
1. Height control indicator lights
2. Height control “OFF” indicator light
When the ignition switch is turned on, all the
indicator lights come on. The indicator light
showing the present mode only remains on
and all other lights go off after a few sec-
onds. This means the system operates correct-
ly.If you change the vehicle height mode,
the indicator lights change as follows:
When changing the vehicle height from
the “N” mode to “HI”:
1. The “N” mode indicator light goes off and the “HI” mode indicator light blinks.
2. After the vehicle height control reaches the “HI” mode, the “HI” mode indicator
light remains on.
If the underbody of the vehicle has
touched the surface on bumpy roads or
the area around the rear suspension is
coated with ice, the vehicle height cannot
be lowered with the height select switch.
The height control indicator lights change
as follows: 1. The present mode indicator light goes
off and the selected mode indicator
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:
When the ignition switch is turned on, this
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 ignition
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 offroad 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.
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.
