Driving assist systems
◆ABS (Anti-lock Brake System) (if equipped)
Helps to prevent wheel lock when the brakes are applied suddenly, or if the
brakes are applied while driving on a slippery road surface
◆Brake assist (if equipped)
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control) (if equipped)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces
◆TRC (Traction Control) (if equipped)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
◆LSD (Limited Slip Differential) (if equipped)
Helps traction when one rear wheel begins to spin by automatically trans-
mitting driving force to the other rear wheel
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator flashes to
indicate that the TRC/VSC sys-
tems are operating.
If the vehicle gets stuck in fresh snow or mud, the TRC/VSC systems
may reduce power from the engine to the wheels. You may need to
turn the system off to enable you to rock the vehicle in order to free it.
■Turning off TRC system only
To turn the TRC system off,
quickly press and release the
switch.
The “TRC OFF” indicator light
will come on.
Press the switch again to turn
the system back on.

Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
● 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 indicate
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.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ Reactivation of the TRC/VSC system s after turning off the engine
Turning off the engine after turning off the TRC/VSC systems will automati-
cally reactivate them.

Reactivation of the TRC system linked to vehicle speed
When only the TRC system is turned off, the TRC system will turn on when
vehicle speed increases. However, when both TRC and VSC systems are
turned off, the systems will not turn on even when vehicle speed increases.
■ If the slip indicator light comes on...
It may indicate a malfunction in the VSC and TRC. Consult any authorized
Toyota dealer or repairer, or another duly qualified and equipped professional.
CAUTION
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten t he vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces

CAUTION
■TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■
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.
■
When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/VSC systems off unless necessary.
■
Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for further in formation when replacing tires or
wheels.
■
Handling of tires and the 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.

DPF (Diesel Particulate Filter) system∗
■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 conventional
diesel vehicle
XVehicles without the DPF system switch
If the DPF system warning light turns on, drive continuously.
( → P. 454)
If the DPF system warning light flashes, have the vehicle inspected by
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional immediately. ( →P. 451)
∗: If equipped
When the deposit collected by the filter reaches a predetermined
amount, it is automatically regenerated.

XVehicles with the DPF system switch
If the DPF system warning light and the indicator light on DPF system
switch turn on or flash, follow the procedure below to regenerate.
Stop the vehicle in a safe place.
Firmly set the parking brake and shift the shift lever to P (automatic
transmission) or N (manual transmission). Release the clutch
pedal.
Do not stop the engine.
Also, make sure that there are no flammable materials near the exhaust
pipe. ( →P. 241)
Press the switch.
The DPF system warning light and
the indicator light on the switch will
change from solid or rapid flashing
to slow flashing, and the idling
engine speed will increase.
Regeneration will take around 20 -
30
* minutes to complete.
When the DPF system warning
light goes out, the idling engine
speed will have finished returning
to normal.
*: Differs in accordance with the outside temperature.

■Regeneration with the DPF system switch (if equipped)
●After pressing the DPF system switch, do not depress the accelerator pedal
or the clutch pedal (manual transmissi on). Depressing the pedal(s) 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. 500)
■ DPF system warning
Under the following driving conditions , the DPF system warning light 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 running
for more than 10 minutes at a time).
*: Differs in accordance with weather, driving conditions, etc.
