Toyota parking assist-sensor  
The distance from your vehicle to nearby obstacles when paral-  
lel parking or maneuvering into a garage is measured by the  
sensors and communicated via an indicator and a buzzer.  
Always check the surrounding area when using this system.

The indicator and buzzer  
When a sensor detects an obstacle, the approximate distance to the  
obstacle is indicated and the buzzer sounds.  
Sensor operation and distance to an obstacle  
The system operates when the vehicle approaches an obstacle, as  
shown by the following table.  
Approximate distance to obstacle  
150 cm (4.9 ft.) to 60 cm (1.9 ft.)

The diagram shows the detec-  
tion range of the sensors. Note  
that the sensors may not be  
able to detect obstacles that are  
extremely close to the vehicle.  
The range of the sensors may  
change depending on the shape  
of the object, etc.

Toyota parking assist-sensor can be operated when  
The engine switch is in the “ON” position and the shift lever is in R.  
Sensor detection information  
Certain vehicle conditions and the surrounding environment may affect the  
ability of a sensor to correctly detect an obstacle. Particular instances where  
this may occur are listed below.  
• There is dirt, snow or ice on a sensor. (Wiping the sensors will resolve  
this problem.)  
• A sensor is frozen. (Thawing the area will resolve this problem.)  
• A sensor is covered in any way.  
• The vehicle is leaning considerably to one side.  
• On an extremely bumpy road, on an incline, on gravel, or on grass.  
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle  
engines, air brakes of large vehicles, or other loud noises producing ultra-  
sonic waves.  
• There is another vehicle equipped with parking assist sensors in the  
vicinity.  
• A sensor is coated with a sheet of spray or heavy rain.  
• The vehicle is equipped with a fender pole or radio antenna.  
• Towing eyelet is installed.

• A bumper or sensor receives a strong impact.  
• The vehicle is approaching a tall or right-angled curb.  
• In harsh sunlight or intense cold weather.  
• A non-genuine Toyota suspension (lowered suspension, etc.) is installed.  
• When attaching a two-way radio antenna.  
• A backlit license plate, license plate holder, etc., are installed.  
In addition to the examples above, there are instances in which, because of  
their shape, signs and other objects may be judged by a sensor to be closer  
than they are.

WARNING  
Caution when using the Toyota parking assist-sensor  
Observe the following precautions.  
Failing to do so may result in the vehicle being unable to be driven safely  
and possibly cause an accident.  
Do not use the sensor at speeds in excess of 10 km/h (6 mph).  
Do not attach any accessories within the sensor range.  
NOTICE  
Notes when washing the vehicle  
Do not apply intensive bursts of water or steam to the sensor area.  
Doing so may result in the sensor malfunctioning.

Driving assist systems  
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.  
ABS (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  
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  
4
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  
EPS (Electric Power Steering)  
Employs an electric motor to reduce the amount of effort needed to  
turn the steering wheel  
When the TRC/VSC systems are operating  
The slip indicator will flash while  
the TRC/VSC systems are operat-  
ing.

Disabling the TRC system  
If the vehicle gets stuck in mud, dirt or snow, the TRC system may  
reduce power from the engine to the wheels. Pressing VSC off switch  
to turn the system off may make it easier for you to rock the vehicle in  
order to free it.  
To turn the TRC system off, quickly press and release the VSC off  
switch.  
The “TRC OFF” indicator will come  
on.  
Press the switch again to turn the  
system back on.  
KBAV450102E  
Turning off both TRC and VSC systems  
To turn the TRC and VSC systems off, press and hold the VSC off switch for  
more than 3 seconds while the vehicle is stopped.  
The “TRC OFF” indicator and the VSC off indicator will come on.  
Press the switch again to turn the systems back on.  
When the “TRC OFF” indicator comes on even if the VSC off switch has  
not been pressed  
TRC cannot be operated. Contact your Toyota dealer.  
Sounds and vibrations caused by the ABS, brake assist, TRC and VSC  
systems  
A sound may be heard from the engine compartment when the brake pedal  
is depressed repeatedly, 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 is oper-  
ating. 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 also 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.

EPS operation sound  
When the steering wheel is operated, a motor sound (whirring sound) may be  
heard. This does not indicate a malfunction.  
Automatic reactivation of TRC and VSC systems  
After turning the TRC and VSC systems off, the systems will be automatically  
re-enabled in the following situations:  
When the engine switch is turned to the “LOCK” position.  
If only the TRC system is turned off, the TRC will turn on when vehicle  
speed increases.  
If both the TRC and VSC systems are turned off, automatic re-enabling will  
not occur when vehicle speed increases.  
Reduced effectiveness of the EPS system  
The effectiveness of the EPS system is reduced to prevent the system from  
overheating when there is frequent steering input over an extended period of  
time. The steering wheel may feel heavy as a result. Should this occur, refrain  
from excessive steering input or stop the vehicle and turn the engine off. The  
EPS system should return to normal within 10 minutes.

If the slip indicator comes on  
It may indicate a malfunction in the systems. Contact your Toyota dealer.

WARNING  
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 wet or slick roads.  
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:  
When driving on dirt, gravel or snow-covered roads  
When driving over bumps in the road  
When driving over roads with potholes or uneven surfaces  
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/VSC systems are operating.  
Drive the vehicle carefully in conditions where stability and power may be  
lost.  
When the VSC is activated  
The slip indicator 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 your Toyota dealer for further information 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 a system to malfunction.
