STARTING AND DRIVING
323
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 systems such as on slippery
roads. If the brake actuator temperature becomes too high
while any of the systems is operating, a buzzer will start to
sound intermittently 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.) At the time, the “VSC TRAC”
warning light will come on and the active traction control
system temporarily stops operating in order to protect the
brake actuator. (Although the active traction control system
does not operate, there is no problem to continue your driving.)
The system will be automatically restored after a short time and
the “VSC TRAC” warning light goes out.
If the light comes on while driving, the active traction control
system does not work. However, as normal braking operates
when being applied, there is no problem to continue your
driving.
In the following cases, contact your Lexus 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 driving.
VEHICLE SKID CONTROL SYSTEM
The vehicle skid control system helps provide integrated
control of the systems such as antilock brake system,
traction control, engine control, etc. This system
automatically controls t he output of the brakes or engine
to help prevent the vehicle from skidding when cornering
on a slippery road surface or operating steering wheel
abruptly.
The vehicle skid control activates when the vehicle speed is
more than following speed:
Four− wheel drive control lever in “H” 15 km/h (9 mph) . . .
Four−wheel drive control lever in “L” 30 km/h (19 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 system is in the
self−check mode, but does not indicate a malfunction.
CAUTION
 Do not rely excessively on the vehicle skid control
system. Even if the vehicle skid control system is
operating, you must always drive carefully and
attentively to avoid serious injury. Reckless driving
will result in an unexpected accident. If the slip
indicator light blinks and an alarm sounds, special
care should be taken while driving.

STARTING AND DRIVING
324
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 skid
control system may not function correctly. When
replacing the tires or wheels, contact your Lexus
dealer.
 In situations where the road surface is covered with
ice or snow, your vehicle should be fitted with snow
tires or tire chains.
 Slip indicator light
If the vehicle is going to skid during driving, the slip indicator
light blinks and an alarm sounds intermittently. Special care
should be taken while driving. 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 Lexus
dealer.
Pushing the center differential lock switch automatically
turns
the vehicle skid control system off. At this time, the
“VSC OFF” indicator comes on with the center differential
lock indicator light.
“VSC OFF” indicator light comes on for a few seconds when
the ignition key is turned to “ON”. It will come on again when
you push the center differential lock switch to turn off the
system.
In the following cases, contact your Lexus dealer:
 The indicator light does not come on when the ignition key
is turned “ON”.

STARTING AND DRIVING

HILLSTART ASSIST CONTROLSYSTEM
The hillstart assist control system assists you in starting
to move up a steep or slippery hill. When you start to move
up the hill slope, the system helps to prevent the vehicle
from rolling backward in the interval while you move your
foot from the brake pedal to the accelerator pedal.
CAUTION
 Do not rely excessively on the hillstart assist control
system. The vehicle may not be able to start
smoothly on road surfaces or offroad surfaces such
as extremely steep slopes or icy roads, on which
sliding can occur very easily.
 Do not use the hillstart assist control system to stop
the vehicle. This system is not designed as a function
for stopping the vehicle on a uphill slope.
The hillstart assist control system will operate for 5
seconds maximally when all of the following conditions
apply.
When the transmission is in any of positions “D”, “4”,
“3”, “2” or “L”
 When the brake pedal is not depressed
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”.
 Slip indicator light
When the hill −start 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.

Automatic notifications
If an airbag deploys, an emergency signal is sent
automatically to the Lexus Link Call Center. In your vehicle, the
system announces “Placing an emergency call to the Lexus
Link Center.” In response to the signal, Lexus Link Advisor will
attempt to communicate with you first. If the Advisor cannot get
any response from you, the Advisor will locate your vehicle
through the GPS, call the nearest emergency services
provider, describe the situation and your location. If necessary,
the Advisor will transfer your call to the emergency services
operator.
If the theft deterrent system on your vehicle is activated,
the Lexus Link System on your vehicle will automatically call
the Lexus Link Call Center. The Advisor will attempt to contact
you to determine whether the alarm is valid.

been stolen, the Advisor will locate, track and provide location
information to the appropriate law enforcement authority. To
protect subscriber privacy, the Lexus Link Call Center will not
provide the location of a vehicle to anyone other than a law
enforcement authority.

“UNLOCK” button on the wireless remote control key within 55
seconds after the alarm was set off, or insert the key into the
door keyhole or ignition switch. The Lexus Link System will
cancel the theft call.NOTICE

call cannot be cancelled.
 This system is only operational in GPS and analog
