Toyota parking assist-sensor
: If equipped
Toyota parking assist-sensor uses sensors in the corners and rear of
the vehicle to detect the distance between the vehicle and any obsta-
cles, and informs the driver of this distance using the warning
beeps.
Sensor types
Rear corner sensors
Back sensors
Toyota parking assist-sensor switch
On/off
To turn the system on, press
the switch. The indicator light
comes on to inform the driver
that the system is operational.
To turn the system off, press
the switch again.

Obstacle detection range
Approx. 50 cm (1.6 ft.)
Approx. 150 cm (4.9 ft.)
The detection area of the sensors
is shown to the left. If obstacles
move too close to the sensors,
they will not be detected.
The range of the sensors may
change depending on the shape
of the object etc.
The Toyota parking assist-sensor can be operated when
The “POWER” switch is in the ON mode, and the shift position is in R.

Sensor detection information
Certain vehicle conditions and the surrounding environment may affect
the ability of the sensor to correctly detect obstacles. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensor will resolve
this problem.)
• The sensor is frozen. (Thawing the sensor will resolve this problem.)
• The sensor is covered in any way.
• In harsh sunlight or intense cold weather.
• When driving bumpy, sloped or gravel roads, or over grass.
• If there is something producing ultrasonic waves nearby, such as
another vehicle’s horn, motorcycle engine noise, air braking sound
from heavy-duty vehicles, or another vehicle using the park assist sys-
tem.
• In heavy rain, or if water is splashed on the sensors.
• The vehicle is leaning considerably to one side.
• If a commercial fender pole or radio antenna is installed.
• If moving towards a high curb or a curb corner.
• If towing eyelet is installed on your vehicle.
• The bumper or sensor receives a strong impact.
• A non-genuine Toyota suspension (lowered suspension etc.) is
installed.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by the sensors to be
closer than they are.
The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles.
• Thin objects such as wire, fencing or rope.
• Objects that absorb sound waves, such as cotton or snow.
• Objects with sharp corners.
• Low objects.
• Objects where the upper section projects out over the lower section.

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
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.

Maintenance and care
UK_AURIS_HV_EE
Aluminum wheels
Remove any dirt immediately by using a neutral detergent. Do not use
hard brushes or abrasive cleaners. Do not use strong or harsh chemical
cleaners.
Use the same mild detergent and wax as used on the paint.
Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
Wash detergent from the wheels immediately after use.
Bumpers
Do not scrub with abrasive cleaners.
CAUTION
When cleaning the windshield (vehicles with rain-sensing windshield
wiper)
Make sure to turn off the wiper switch.
If the switch is left in the “AUTO” position, the windshield wiper may operate
unexpectedly in the following situations. Failure to turn off the wiper switch
may possibly result in hands being caught or other serious injuries and
cause damage to the windshield wiper.
When the upper part of the windshield where the raindrop sensor is
located is touched by hand
When a wet rag or similar is held close to the raindrop sensor
If something bumps against the windshield
If you directly touch the sensor body or if something bumps into the sensor
Caution about the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled
sufficiently, as touching a hot exhaust pipe can cause burns.
