●The shape of the obstacle may prevent a sensor from detecting i t. Pay par-
ticular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehicle
● The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sen sor.
• There will be a short delay between obstacle detection and dis play. Even
at slow speeds, there is a possibility that the obstacle will c ome within the
sensor’s detection areas before the display is shown and the bu zzer
sounds.
• Thin posts or objects lower than the sensor may not be detecte d when
approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.
■ If “Clean Parking Assist Sensor” is displayed on the multi-information
display
A sensor may be dirty or covered with snow or ice. In such case s, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a mal function dis-
play may appear or an obstacle may not be detected. If the sens or thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction” is displayed on the multi-information dis-
play
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by your Toyota dealer.
■ Customization
Settings (e.g. buzzer sounds volume) can be changed.

Driving assist systems
◆Multi Terrain ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenl y, or if the
brakes are applied while driving on a slippery road surface, or in off-road
conditions (such as rough roads, sand and mud)
◆Brake assist
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)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces
◆Active TRAC (Traction Control)
Helps to maintain drive power and prevent the 4 wheels from spi nning
when starting the vehicle or accelerating on slippery roads, or in off-road
conditions
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when start ing on
an incline or slippery slope
◆KDSS (Kinetic Dynamic Suspension System)
KDSS helps to enhance ride comfort and handling response by usi ng a
hydraulic control system to control the suspension stabilizer b ars in
response to road surface and driving conditions during cornerin g or off-
road driving
To help enhance driving safety and performance, the following
systems operate autom atically 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.

■Automatic reactivation of Active TRAC, VSC and Trailer Sway Con trol
Turning the engine switch off after turning off the Active TRAC and VSC sys-
tems will automatically re-enable them.
■ Automatic Active TRAC reactivation
If only the Active TRAC system is turned off, the Active TRAC s ystem will turn
on when vehicle speed increases.
■ Automatic Active TRAC, VSC and T railer Sway Control reactivation
If the Active TRAC, VSC and Trailer Sway Control are turned off, the systems
will not turn on even when vehicle speed increases.
■ If the brake system overheats
The brake system may overheat. In this case, a buzzer will soun d, and the
TRAC OFF indicator will flash, and Active TRAC and hill-start a ssist control
will be temporarily inoperable. In this event, stop the vehicle immediately in a
safe place, and allow the brake system to cool down sufficientl y until the
TRAC OFF indicator go off. (There is no problem with continuing normal driv-
ing.)
■ Sounds and vibrations caused by the Multi Terrain ABS, brake assist,
Active TRAC, VSC, Trailer Sway Control, hill-start assist contr ol and
VGRS
● A sound may be heard from the engine compartment when the engin e is
started or just after the vehicle begins to move. This sound do es not indicate
that a malfunction has occurred in any of these systems.
● Any of the following conditions may occur when the above system s are
operating. None of these indicates that a malfunction has occur red.
• 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 Multi Terrain ABS is acti- vated.
• The brake pedal may move down slightly after the Multi Terrain ABS is
activated.
■ Hill-start assist control is operational when
●The shift lever is in D or S.
● The brake pedal is not depressed.
■ VGRS is disabled in the following situations
●During stopping or the steering wheel has been moved for a long time while
driving at lower speeds.
● After the engine is restarted at less than -22 F (-30 C).
● If you disconnect the battery with the steering wheel turned, the center posi-
tion of the steering wheel could be slightly and temporary hanged. To initial-
ize the VGRS, drive for a short while.

WARNING
Any of the following conditions may result in an accident which could cause
death or serious injury:
■ The Multi Terrain ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (suc h 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 Multi Terrain ABS is operating may exceed
that of normal conditions
The Multi Terrain ABS is not designed to shorten the vehicle’s stopping dis-
tance. Always maintain a safe distance from the vehicle in fron t 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 roads
■ Active TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the Active TRAC is operating.
Do not drive the vehicle in conditions where stability and powe r 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 TRAC, VSC and Trailer Sway Control are off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As there are systems to help ensure vehicle stability an d driving force,

Reckless driving may cause an accident. Exercise particular car e when the
indicator light flashes.
■
Replacing tires
Make sure that all tires are of the same size, brand, tread pat tern and
total load capacity. In addition, make sure that the tires are inflated to
the specified tire pressure level.
The Multi Terrain ABS, Active TR AC, VSC and Trailer Sway Control will
not function correctly if different tires are fitted on the veh icle.
Contact your Toyota dealer for further information when replaci ng tires
or wheels.
■Handling of tires and suspension
Using tires with any kind of probl em or modifying the suspension will
affect the driving assist system s, and may cause the system to malfunc-
tion.
■ Trailer 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 environment, the Trailer Swa y Control sys-
tem may not be effective. Refer to your trailer owner’s manual for informa-
tion on how to tow your trailer properly.
■ If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
● Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering w heel.
● Begin releasing the accelerator pedal immediately but very grad ually 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. 207)
