Object Detection Systems

Ultrasonic Rear Parking Assist (URPA)

For vehicles with the URPA system, it operates at speeds less than 8 km/h (5 mph), and assists the driver with parking and avoiding objects while in R (Reverse).

The sensors on the rear bumper are used to detect the distance to an object up to 2.5 m (8 ft) behind the vehicle, and at least 25 cm (10 in) off the ground.

WARNING:
The Ultrasonic Rear Parking Assist (URPA) system does not replace driver vision. It cannot detect:
• objects that are below the bumper, underneath the vehicle, or if they are too close or far from the vehicle
• children, pedestrians, bicyclists, or pets.
If you do not use proper care before and while backing; vehicle damage, injury, or death could occur. Even with URPA, always check behind the vehicle before backing up. While backing, be sure to look for objects and check the vehicle’s mirrors.

The display is located on

The display is located on the rear shelf, below the rear window, and can be seen by looking over your right shoulder.

URPA uses three color-coded lights to provide distance and system information.

How the System Works

URPA comes on automatically when the shift lever is moved into R (Reverse). The rear display briefly illuminates to indicate the system is working.

URPA operates only at speeds less than 8 km/h (5 mph). If the vehicle is above this speed, the red light on the rear display will flash.

To be detected, objects must be at least 25 cm (10 in) off the ground and below trunk level. Objects must also be within 2.5 m (8 ft) from the rear bumper. This distance may be less during warmer or humid weather.

A single beep will sound the first time an object is detected between 1 m (40 in) and 2.5 m (8 ft) away.

Beeping will occur continuously when the vehicle is at 0.6 m (23 in) or closer to an object.

The following describes what will occur with the URPA display as the vehicle gets closer to a detected object:

The system can be disabled through the Driver

The system can be disabled through the Driver Information Center (DIC). See “Park Assist” under DIC Operation and Displays for more information.

When the System Does Not Seem to Work Properly

If the URPA system will not activate due to a temporary condition, the message PARK ASSIST OFF will be displayed on the DIC and a red light will be shown on the rear URPA display when the shift lever is moved into R (Reverse). This occurs under the following conditions:

• The driver disables 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 Washing Your Vehicle.

• A trailer was attached to the vehicle, or a bicycle or an object was hanging out of the trunk during the last drive cycle, the red light may illuminate in the rear display. Once the attached object is removed, URPA will return to normal operation.

• A tow bar is attached to the vehicle.

• The vehicle’s bumper is damaged. Take the vehicle to your dealer/retailer to repair the system.

• Other conditions may affect system performance, such as vibrations from a jackhammer or the compression of air brakes on a very large truck.

If the system is still disabled after driving forward at least 25 km/h (15 mph), take the vehicle to your dealer/retailer.

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 is only a lane changing aid and does not replace driver vision. SBZA does not detect:
• Vehicles outside the side blind zones which may be rapidly approaching.
• Pedestrians, bicyclists, or animals.
Failure to use proper care when changing lanes may result in damage to the vehicle, injury, or death. Always check the outside and rearview mirrors, glance over your shoulder, and use the turn signal before 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

The SBZA sensor covers a zone of approximately one lane over from both sides of the vehicle, 3.5 m (11 ft).

This zone starts at each side mirror and goes back approximately 5 m (16 ft). The height of the zone is approximately between 0.5 m (1.5 ft) and 2.0 m (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

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 then 20 mph (32 km/h), 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 the Driver Information Center (DIC). See Driver Information Center (DIC) 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/retailer.

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, slush, or in heavy rainstorms. For cleaning instructions, see Washing Your Vehicle. If the DIC still displays the SIDE BLIND ZONE SYS. UNAVAILABLE message after cleaning the bumper, see your dealer/retailer.

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 the DIC. The SIDE BLIND ZONE ALERT 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 in the DIC:

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, slush, or even heavy rainstorms.

This message may also activate during heavy rain or due to road spray. The vehicle does not need service.

For cleaning, see Washing Your Vehicle.

SERVICE SIDE 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/retailer.

Lane Departure Warning (LDW)

The vehicle may have a Lane Departure Warning (LDW) system. Read this entire section before using the system.

WARNING:
The Lane Departure Warning (LDW) system does not steer the vehicle and is only an aid to help you stay in your driving lane. The LDW system may not:
• Provide you with enough time to avoid a lane change collision.
• Be loud enough for you to hear the warning beeps.
• Work properly under bad weather conditions or if the windshield is not kept clean.
• Detect lane markings and will not detect road edges.
• Warn you that your vehicle is crossing a lane marking if the system does not detect the lane marking.
LDW will indicate the system is working whenever it detects either the left or right lane marking. So if you depart on the side of the lane that LDW is not detecting, LDW will not warn you.
If you do not carefully maintain your vehicle position within the lane, vehicle damage, injury, or death could occur. Even with LDW, always keep your attention on the road and maintain proper vehicle position within the lane. Always keep the windshield clean and do not use LDW in bad weather conditions.

When the vehicle crosses a detected lane marking, the LDW symbol will flash and you will hear three beeps.

LDW will not warn you if the turn signal is on or if you make a sharp maneuver. Before making a lane change, check the vehicle’s mirrors, glance over your shoulder for vehicles and hazards, and start the turn signal before changing lanes.

How the System Works

LDW uses a camera located between the inside rearview mirror and the windshield to detect the lane markings.

LDW on and off, (Lane Departure Warning): To turn LDW on and off, press the LDW control, located by the exterior headlamp control. An indicator on the control will light to indicate that LDW is on.

When the vehicle is started, the LDW symbol, located

When the vehicle is started, the LDW symbol, located in the instrument panel cluster, will briefly come on to indicate that the light is operational.

LDW only operates at speeds of 35 mph (56 km) or greater. If LDW is turned on when traveling at these speeds, the LDW symbol will appear green if the system detects a left or right lane marking. This symbol will change to amber and flash and three beeps will sound if you cross a detected lane marking without using the turn signal.

If the LDW symbol does not appear, LDW is not currently operating and will not warn you.

To change the volume of the warning chime, see Chime Volume under DIC Vehicle Customization for more information.

When the System Does Not Seem To Work Properly

The LDW symbol will not appear when the system is having difficulty seeing the lines on the road or if the view of the camera on the windshield is blocked with mud, dirt, snow, ice, or slush, if the windshield is damaged, or when weather limits visibility, such as while driving in fog, rain, or snow conditions. This is normal operation, the vehicle does not need service. For cleaning instructions, see Washing Your Vehicle.

LDW warnings may occasionally occur due to tar marks, shadows, cracks in the road, or other road imperfections.

This is normal system operation, the vehicle does not need service.

LDW Error Message

SERVICE LANE DEPARTURE SYSTEM: This message may appear in the DIC to indicate that LDW is not working properly. If this message remains on after continued driving, the system needs service. Take your vehicle to your dealer/retailer.

LANE DEPARTURE SYSTEM UNAVAILABLE: This message may appear in the DIC if LDW does not activate due to a temporary condition.
