Driving assist systems
XABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if the
brakes are applied while driving on a slippery road surface
XBrake assist (if equipped)
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
XVSC (Vehicle Stability Control) (if equipped)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces
XTRC (Traction Control) for Pre Runner and H2 position on 4WD
models (if equipped)
Helps to maintain drive power and pr event the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
XA-TRC (Active Traction Control) for H4 and L4 position on 4WD
models (if equipped)
Helps to maintain drive power and prevent the four wheels from spinning
when starting the vehicle or accelerating on slippery roads
XHill-start assist control (if equipped)

an uphill
XEmergency brake signal (if equipped)
When the brakes are applied suddenly, the emergency flashers automati-
cally flash to alert the vehicle behind.
To keep driving safety and performance, the following systems
operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehi-
cle.

QOperating tips (vehicles with automatic transmission)
The system will operate when the shift lever is in a position other than P, how-
ever to make effective use of the system it is recommended to select a lower
shift range.
Q The system will not operate when
O The transfer mode is in H2.
O The rear differential is locked. (if equipped)
Q If the downhill assist control system indicator flashes
O In the following situations, the indicator flashes and the system will not oper-
ate:
• The transfer mode is not in L4 or H4.
• The rear differential is locked. (if equipped)
• The shift lever is in P. (vehicles with automatic transmission)
• The accelerator or brake pedal is depressed.
• The vehicle speed exceeds approximately 30 km/h (18 mph).
• The brake system overheats.
O In the following situations, the indicator flashes to alert the driver, but the
system will operate:
• The shift lever is in N. (vehicles with automatic transmission)
• The clutch pedal is depressed. (vehicles with manual transmission)
• The “DAC” switch is turned off while the system is operating.
The system will gradually ceases operat ion. The indicator will flash during
operation, and then go off when the system is fully off.
Q When the downhill assist control system is operated continuously
This may cause the brake actuator to overheat. In this case, the downhill
assist control system will stop operating, a buzzer will sound and the downhill
assist control system indicator will start flashing, and “TRC turned off” will be
shown on the multi-information display. Refrain from using the system until
the downhill assist control system indicator stays on and the message goes
off. (The vehicle can be driven normally during this time.)
Q Sounds and vibrations caused by the downhill assist control system
O 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 downhill assist control system.

QIf the engine is turned off and restarted
The AUTO LSD system and the indicators are automatically turned off.
Q Reactivation of the VSC system linked to vehicle speed
When the AUTO LSD system is turned on, the VSC and TRC systems will
turn on automatically if vehicle speed increase.
Q If the brake system overheats
The system will cease operation and a buzzer will alert the driver. At this time,
the “AUTO LSD” indicator will flash and “TRC turned off” will be shown on the
multi-information display. Stop the vehicle in a safe place. (There is no prob-
lem with continuing normal driving.) The system will be automatically restored
after a short time.
WARNING
Q To avoid an accident
Failure to do so, a much greater steer ing effort and more careful cornering
control will be required.
O Do not use the AUTO LSD system in conditions other than when one of
the drive wheels spinning occurs in a ditch or rough surface.
O Do not drive with the AUTO LSD system continuously turned on.
NOTICE
QActivating while driving
Do not activate the AUTO LSD system if the wheel is slipping. Stop the slip-
ping or spinning before activating.

When regenerating the filter by pressing the DPF system switch
Stop the vehicle in a safe place.
Shift the shift lever to P (automatic transmission) or N (manual
transmission), and firmly set the parking brake.
Do not stop the engine.
Also, make sure that there are no flammable materials near the exhaust
pipe. ( P. 369)
Check the engine is warmed up. If the engine is cold, warm up the engine
by depressing the accelerator pedal.*1
Press the DPF system switch.
The DPF system warning message
shown in the illustration appears
on the multi-information display,
and the idling engine speed will
increase.
Regeneration will take around 15 -
40 minutes to complete.*2
When the DPF system warning message disappears on the multi-
information display, the idling engine speed will have finished return-
ing to normal.
The DPF system switch may not operate when the vehicle is higher
than 4000 m (13123 ft.) above sea level.
*1: Depending on the situation, it may be necessary to depress the acceler-
ator pedal until the engine speed is increased to 3000 rpm. If the engine
coolant temperature or exhaust gas temperature is low, it may take a
long time to regenerate, or regeneration may be impossible.
*2: Time required for regeneration differs in accordance with the outside
temperature. Also, if the engine speed is still approximately 2000 rpm
10 minutes after pressing the DPF system switch, the exhaust gas tem-
perature may be low. In this case, depress the accelerator pedal to run
the engine at approximately 3000 rpm for a while.
When depressing the accelerator pedal, regeneration will be stopped. In
this case, restart regeneration.

appears on the multi-information display and a buzzer sounds (mal-
function indicator lamp comes on), have the vehicle inspected by
any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer immediately.
Q Regeneration with the DPF system switch
O After pressing the DPF system switch, depressing the accelerator pedal or
clutch pedal (manual transmission) will stop regeneration. If regeneration
has been stopped, restart regeneration as soon as possible.
O After regeneration is finished, race the engine several time to clean the
exhaust system.
Q DPF system warning
Under the following driving conditions, the DPF system warning message
may be displayed on the multi-information display earlier than normal.*
O When only driving at low speeds (for example 20 km/h [12 mph] or below).
O 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.
NOTICE
Q If the malfunction indicator lamp comes on (warning buzzer)
The malfunction indicator lamp comes on if you continue driving while the
DPF system warning message appears on the multi-information display. In
this event, damage may be caused to the vehicle or an accident may occur.
Have the vehicle inspected by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer immediately.
