If You Cannot See the HUD Image
When the Ignition Is On
• Is anything covering the HUD lens?
• Is the HUD dimmer setting bright enough?
• Is the HUD image adjusted to the proper
height?
• Are you wearing polarized sunglasses?
• Still no HUD image? Check the fuse in the
instrument panel fuse block. See Instrument
Panel Fuse Block on page 490.
If the HUD Image Is Not Clear
• Is the HUD image too bright?
• Are the windshield and HUD lens clean?
If the HUD image is not correct, contact your
dealer/retailer.
Keep in mind that the windshield is part of the
HUD system.
Ultrasonic Rear Parking
Assist (URPA)
If your vehicle has the Ultrasonic Rear Parking
Assist (URPA) system it is designed to help
you park while in Reverse (R). It operates only
at speeds less than 5 mph (8 km/h). URPA
helps make parking easier and helps you avoid
colliding with objects such as parked vehicles.
The URPA system detects objects that are close
to the rear of the vehicle which are at least
10 inches (25.4 cm) off the ground and below
hood or trunk level. The system detects objects
up to 8 feet (2.5 m) behind your vehicle. The
URPA sensors determine how close these objects
are from your bumper within this area.
