Ultrasonic Parking Assist
If available, the Ultrasonic Rear Parking Assist (URPA) system assists the driver with parking and avoiding objects while in R (Reverse). URPA operates at speeds less than 8 km/h (5 mph).
The sensors on the rear bumper detect objects up to 2.5 m (8 ft) behind the vehicle, and at least 20 cm (8 in) off the ground.
WARNING!
The URPA system does not
detect pedestrians, bicyclists,
animals, or any other objects
located below the bumper or that
are too close or too far from the
vehicle. To prevent injury, death,
or vehicle damage, even with
URPA, always check behind the
vehicle and check all mirrors
before backing.
How the System Works
URPA comes on automatically when the shift lever is moved into R (Reverse). A single tone sounds to indicate the system is working.
URPA operates only at speeds less than 8 km/h (5 mph).
An obstacle is indicated by audible beeps. The interval between the beeps becomes shorter as the vehicle gets closer to the obstacle.
When the distance is less than 30 cm (12 in) the beeping is a continuous tone for five seconds.
To be detected, objects must be at least 20 cm (8 in) off the ground and below trunk level. Objects must also be within 2.5 m (8 ft) from the rear bumper. The distance at which objects can be detected may be less during warmer or humid weather.
Turning the System On and Off
The URPA system can be turned on and off using the park assist button located next to the shift lever.
The LED next to the park assist button lights up when the system is on and turns off when it has been disabled.
When the system is off, PARK ASSIST OFF displays on the Driver Information Center (DIC). The message disappears after a short period of time.
URPA defaults to the on setting each time the vehicle is started.
When the System Does Not Seem to Work Properly
The following messages may be displayed on the DIC:
SERVICE PARK ASSIST: If this message occurs, take the vehicle to your dealer to repair the system.
PARK ASSIST OFF: If the URPA system does not activate due to a temporary condition, this message displays on the DIC. This can occur under the following conditions:
• The driver has disabled the system.
• The ultrasonic sensors are not clean. Keep the vehicle's rear bumper free of mud, dirt, snow, ice, and slush. For cleaning instructions, see Exterior Care.
• The park assist sensors are covered by frost or ice. Frost or ice can form around and behind the sensors and may not always be seen; this can occur after washing the vehicle in cold weather. The message may not clear until the frost or ice has melted.
• An object was hanging out of the trunk during the last drive cycle.
Once the object is removed, URPA will return to normal operation.
• The bumper is damaged. Take the vehicle to your dealer to repair the system.
• Other conditions, such as vibrations from a jackhammer or the compression of air brakes on a very large truck, are affecting system performance.
Side Blind Zone Alert (SBZA)
The vehicle may have a Side Blind Zone Alert (SBZA) system. Read this entire section before using the system.
WARNING!
SBZA does not detect vehicles
rapidly approaching outside of the
side blind zones, pedestrians,
bicyclists, or animals. Failure to
use proper care when changing
lanes may result in injury, death,
or vehicle damage. Always check
for other vehicles and use the
turn signals when changing lanes.
When the system detects a vehicle in the side blind zone, amber SBZA displays will light up in the side mirrors. This indicates that it may be unsafe to change lanes. Before making a lane change, always check the SBZA display, check the outside and rearview mirrors, look over your shoulder for vehicles and hazards, and use the turn signal.
SBZA Detection Zones
The SBZA sensor covers a zone of approximately one lane over from both sides of the vehicle, or 3.5m(11 ft). This zone starts at each side mirror and goes back approximately 5.0 m(16 ft). The height of the zone is approximately between 0.5 m(1.5 ft) and 2.0m(6 ft) off the ground.
The SBZA detection zones do not change if the vehicle is towing a trailer. So be extra careful when changing lanes while towing a trailer.
How the System Works
When the vehicle is started, both outside mirror displays will briefly come on to indicate that the system is operating. While driving forward, the left or right side mirror SBZA display will light up if a vehicle is detected in that blind zone. If you activate a turn signal and a vehicle has been detected on the same side, the SBZA display will flash to give you extra warning not to change lanes.
SBZA displays do not come on while the vehicle is approaching or passing other vehicles. At speeds greater than 32 km/h (20 mph), SBZA displays may come on when a vehicle you have passed remains in or drops back into the detection zone.
SBZA can be disabled through vehicle personalization. See Vehicle Personalization for more information. If the SBZA is disabled by the driver, the SBZA mirror displays will not light up during normal driving.
When the System Does Not Seem to Work Properly
Occasional missed alerts can occur under normal circumstances and will increase in wet conditions. The system does not need to be serviced due to an occasional missed alert. The number of missed alerts will increase with increased rainfall or road spray.
If the SBZA displays do not light up when the system is on and vehicles are in the blind zone, the system may need service. Take the vehicle to your dealer.
SBZA is designed to ignore stationary objects; however, the system may occasionally light up due to guard rails, signs, trees, shrubs, and other stationary objects.
This is normal system operation; the vehicle does not need service.
SBZA does not operate when the left or right corners of the rear bumper are covered with mud, dirt, snow, ice, or slush, or in heavy rainstorms. For cleaning instructions, see Exterior Care. If the infotainment display still shows the SIDE BLIND ZONE SYS. UNAVAILABLE message after cleaning the bumper, see your dealer.
The SBZA displays may remain on if a trailer is attached to the vehicle, or a bicycle or object is extending out to either side of the vehicle.
When SBZA is disabled for any reason other than the driver turning it off, the driver will not be able to turn SBZA back on using vehicle personalization. The On option will not be selectable if the conditions for normal system operation are not met. Until normal operating conditions for SBZA are met, you should not rely upon SBZA while driving.
SBZA Error Messages
The following messages may appear on the infotainment display:
SIDE BLIND ZONE ALERT SYSTEM OFF: This message indicates that the driver has turned the system off.
SIDE BLIND ZONE SYS.
UNAVAILABLE: This message indicates that the SBZA system is disabled because the sensor is blocked and cannot detect vehicles in the blind zone. The sensor may be blocked by mud, dirt, snow, ice, or slush. This message may also activate during heavy rain or due to road spray. The vehicle does not need service. For cleaning, see Exterior Care.
SERVICE BLIND ZONE ALERT SYSTEM: If this message appears, both SBZA displays will remain on indicating there is a problem with the SBZA system. If these displays remain on after continued driving, the system needs service. Take the vehicle to your dealer.
