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)
Helps to reduce the backward movement of the vehicle when starting on
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.

XTrailer Sway Control (if equipped)
Helps the driver to control trailer sway by selectively applying brake pres-
sure for individual wheels and reducing driving torque when trailer sway is
detected.
Trailer Sway Control is part of the VSC system and will not operate if VSC
is turned off or experiences a malfunction.
The slip indicator will flash while
the TRC/A-TRC/VSC/Trailer
Sway Control systems are operat-
ing.

Q Automatic reactivation of TRC, A-TRC, VSC and Trailer Sway Control
systems
After turning the TRC, A-TRC, VSC and Trailer Sway Control systems off, the
systems will be automatically re-enabled in the following situations:
O When the engine switch is turned to the “LOCK” position (vehicles without
smart entry & start system) or off (vehicles with smart entry & start system).
O If only the TRC/A-TRC system is turned off (P. 357), the TRC/A-TRC will
turn on when vehicle speed increases.
If the TRC, A-TRC, VSC and Trailer Sway Control systems are turned off
( P. 359), automatic re-enabling will not occur when vehicle speed
increases.
Q Operating conditions of the hill-start assist control
When the following four conditions are me t, the hill-start assist control will
operate:
O Vehicles with automatic transmission: The shift lever is in a position other
than P or N (when starting off forward/backward on an upward incline)
Vehicles with manual transmission: The shift lever is in a position other than
R when starting off forward on an upward incline, or the shift lever is in R
when starting off backward on an upward incline.
O The vehicle is stopped
O The accelerator pedal is not depressed
O The parking brake is not engaged
Q Automatic system cancelation of the hill-start assist control
The hill-start assist control will turn off in any of the following situations:
O Vehicles with automatic transmission: The shift lever is shifted to P or N
Vehicles with manual transmission: The shift lever is shifted to R when start-
ing off forward on an upward incline, or the shift lever is shifted to other than
R when starting off backward on an upward incline.

Q Operating conditions of emergency brake signal
When the following conditions are met, the emergency brake signal will oper-
ate:
O The emergency flashers are off.
O Actual vehicle speed is over 55 km/h (35 mph).
O The system judges from the vehicle deceleration that it is a sudden braking
operation.
Q Automatic system cancelation of emergency brake signal
The emergency brake signal will be canceled in any of the following situa-
tions:
O The emergency flashers are turned on.
O The system judges from the vehicle deceleration that is not a sudden brak-
ing operation.
WARNING
Q The ABS does not operate effectively when
O The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
O The vehicle hydroplanes while driving at high speed on wet or slick roads.
Q Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
O When driving on dirt, gravel or snow-covered roads
O When driving with tire chains
O When driving over bumps in the road
O When driving over roads with potholes or uneven surfaces

WARNING
QTRC/A-TRC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/A-TRC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
Q Hill-start assist control does not operate effectively when
O 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 with ice.
O Unlike the parking brake, the hill-start assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not attempt to use
the hill-start assist control to hold the vehicle on an incline, as doing so
may lead to an accident.
Q When the TRC/VSC/Trailer Sway Control is activated
The slip indicator flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator flashes.
Q When the TRC/A-TRC/VSC/Trailer Sway Control 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/A-TRC/VSC/Trailer Sway Control systems off
unless necessary.
Q 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, A-TRC, VSC, Trailer Sway Control, hill-start assist control
and downhill assist control systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
Q 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 a system to malfunction.

WARNING
QTrailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations. Depending on many factors such as the conditions of the vehicle,
trailer, road surface, and driving envi ronment, the Trailer Sway Control sys-
tem may not be effective. Refer to your trailer owner’s manual for informa-
tion on how to tow your trailer properly.
Q If trailer sway occurs (vehicles with Trailer Sway Control)
Observe the following precautions.
Failing to do so may cause death or serious injury.
O Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway by turning the steering wheel.
O Begin releasing the accelerator pedal immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. ( P. 215)
