on even when vehicle speed increases.
If the brake system overheats
The brake system may overheat. In this case, a buzzer will sound, and the
“TRC OFF” will be displayed on the multi-information display, and Active
TRC and hill-start assist control will be temporarily inoperable. In this event,
stop the vehicle immediately in a safe place, and allow the brake system to
cool down sufficiently until the “TRC OFF” on the multi-information display
go off. (There is no problem with continuing normal driving.)
Sounds and vibrations caused by the Multi Terrain ABS, brake assist,
Active TRC, VSC, hill-start assist control and VGRS
A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in any of these systems.
Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.

CAUTION
Active TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the Active TRC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
If the hill-start assist control does not operate effectively
Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered in ice.
When Active TRC and VSC are off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As there are systems to help to ensure vehicle stability and driving
force, do not turn off Active TRC and VSC unless necessary.
When the VSC is activated
The slip indicator light flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator light flashes.
Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the speci-
fied tire pressure level.
The Multi Terrain ABS and VSC will not function correctly if different tires are
fitted on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for further information when replacing tires or
wheels.
Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.

NOTICE
KDSS
In the following situations, there is the possibility that a system malfunction
has occurred, and drive comfort and the vehicle’s ability to travel on poor
road surfaces may be reduced. Take the vehicle to any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional imme-
diately.
When turning a corner, the vehicle’s body seems to roll further than nor-
mal.

PCS (Pre-Crash Safety)
: If equipped
The pre-crash safety is operational when
Vehicle speed exceeds 30 km/h (19 mph).
The system detects sudden braking or skidding.
The front occupants are wearing a seat belt.
When there is a malfunction in the system

(P. 579)
CAUTION
Limitations of the pre-crash safety
Do not rely on the pre-crash safety system. Always drive safely, taking care
to observe your surroundings and checking for any obstacles or other road
hazards.
The system detects emergency braking from the speed and force
with which the driver presses the brake pedal, and quickly tightens
the seat belt to assist the effectiveness of the seat belt pretension-
ers (P. 96). This system also operates in the same manner when
the driver loses control of the vehicle.
