The corner and center sensors monitor obstacles around your vehicle, and the
beeper, multi-information display and audi o/information screen let you know the
approximate distance between your vehicle and the obstacle.
■The sensor location and range
1 Parking Sensor System*
Even when the system is on, always confirm if there is
no obstacle near your ve hicle before parking.
The system may not work properly when:

dirt.
•The vehicle is on uneven su rface, such as grass,
bumps, or a hill.
•The vehicle has been out in hot or cold weather.•The system is affected by devices that emit
ultrasonic waves.
•Driving in bad weather.
The system may not sense:
•Thin or low objects.•Sonic-absorptive materials, such as snow, cotton,
or sponge.
•Objects directly under the bumper.
Do not put any accessories on or around the sensors.Front: Within about 24 in (60 cm) or less

uuParking Your Vehicle uCross Traffic Monitor*
Continued
Driving
Cross Traffic Monitor*
Monitors the rear corner areas using the radar sensors when reversing, and alerts
you if a vehicle approaching from a rear corner is detected.
The system is convenient when you are backing out of a parking space.1Cross Traffic Monitor*
The parking sensor system’s alerting buzzer overrides
the Cross Traffic Monitor buzzer when the sensors
are detecting obstacles at the closest range.
3CAUTION
Cross Traffic Monitor cannot detect all
approaching vehicles and may not detect
an approaching vehicle at all.
Failure to visually confirm that it is safe to
back up the vehicle before doing so may
result in a collision.
Do not solely rely on the system when
reversing; always also use your mirrors, and
look behind and to the sides of your vehicle
before reversing.

The system activates when:
• The power mode is in ON.
• The Cross Traffic Monitor is turned on.
2 Cross Traffic Monitor On and Off P. 480
•The transmission is in (R.
• Your vehicle is moving at 3 mph (5 km/h) or
lower.
When a vehicle is detected approaching from a rear corner, Cross Traffic Monitor
alerts you with a buzzer and a displayed warning.
The system will not detect a vehicle that approaches from directly behind your
vehicle, nor will it provide alerts about a detected vehicle when it moves directly
behind your vehicle.
The system does not provide alerts for a vehicle that is moving away from your
vehicle, and it may alert for pedestri ans, bicycles, or stationary objects.
■How the System Works1Cross Traffic Monitor*
Cross Traffic Monitor may not detect or may delay
alerting an approach ing vehicle, or may alert without
an approaching vehicle under the following
conditions:
•An obstacle, such as a nother vehicle and a wall,
near your vehicle’s rear bumper, is blocking the
radar sensor’s scope.
•Your vehicle is moving at the speed of about 3 mph
(5 km/h) or higher.
•A vehicle is approaching at the speed other than
between about 6 mph (10 km/h) and 16 mph
(25 km/h).
•The system picks up external interference such as
other radar sensors from an other vehicle or strong
radio wave transmitted fr om a facility nearby.
•Either corner of the rear bumper is covered with
snow, ice, mud or dirt.
•When there is bad weather.
•Your vehicle is on an incline.
•Your vehicle is tilted due to a heavy load in the rear.•Your vehicle is reversing towards a wall, a pole, a
vehicle, and so on.
The rear bumper or the sens ors have been improperly
repaired or the rear bum per has been deformed.
Have your vehicle checked by a dealer.
For proper operation, always keep the rear bumper
corner area clean.
Do not cover the rear bumper corner area with labels
or stickers of any kind.
