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.
If after the vehicle has been left in a slanted position for a long time, for
example with the wheels of one side parked on a curb, the vehicle does
not return to level when driving (the vehicle remains slanted to one side
after returning the vehicle to level ground).

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
Warning message will be displayed on the multi-information display.
(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.

Regeneration
Regeneration is performed as necessary in accordance with
driving conditions.
System characteristics
The DPF system has the following characteristics:
Idle speed increases during regeneration
The smell of the exhaust gas differs from that of a conven-
tional diesel vehicle

The DPF system warning mes-
sage “DPF MANUAL REGENER-
ATION IN PROCESS” appears on
the display, and the idling engine
speed will increase.
Regeneration will take around 20

Regeneration with the DPF switch
After pressing the DPF switch, do not depress the accelerator pedal.
Depressing the pedal will stop regeneration. If regeneration has been
stopped, restart regeneration as soon as possible.
If regeneration is carried out while the exhaust pipe is hot (for example
directly after driving), it will take less time than when the engine is cold.
Replacing the engine oil
Make sure to use an oil of the recommended grade or of matching quality.
(P. 652)
DPF system warning
Under the following driving conditions, the DPF system warning message
may come on earlier than normal.
*
When only driving at low speeds (for example 20 km/h [12 mph] or
below).
If the engine is turned on and off frequently (if the engine is not left run-
ning for more than 10 minutes at a time).
*: Differs in accordance with weather, driving conditions, etc.
