Troubleshooting
Possible CauseSymptom
You may have switched the traction control off.The system does not search for a parking space.
The transmission is in reverse (R). Your vehicle must be moving forward to be able todetect a parking space.
The sensors may be blocked. For example, snow, ice or dirt buildup. Blocked sensorscan affect how the system functions.The system does not offer a parking space.
There is not enough room in the parking space for your vehicle to safely park.
There is not enough space for the parking maneuver on the opposite side of the parkingspace.
The parking space is more than 5 ft (1.5 m) or less than 2 ft (0.5 m) away.
The vehicle speed is greater than 22 mph (35 km/h) for parallel parking or greater than19 mph (30 km/h) for perpendicular parking.
You recently disconnected or replaced the battery. After you reconnect the battery youmust drive your vehicle on a straight road for a short period of time.
Your vehicle is rolling in the opposite direction of the current transmission position. Forexample, rolling forward when in reverse (R).The system does not correctly position your vehiclein a parking space.
An irregular curb along the parking space prevents the system from correctly aligningyour vehicle.

Optimal performance may not occur if:
•The camera is blocked.
•There is poor visibility or lightingconditions.
•There are bad weather conditions.
System Not Available
The system may not turn on if there is:
•A blocked sensor.
•High brake temperature.
•A failure in the system or a relatedsystem.
Blocked Sensor
Note:You cannot see the radar sensor. It isbehind a fascia panel.
A message displays if something obstructsthe radar signals from the sensor. Thesensor is in the lower grille. The systemcannot detect a vehicle ahead and does notfunction when something blocks the sensor.
Possible Causes and Actions for This Message Displaying:
ActionCause
Clean the grille surface in front of the radar or remove the objectcausing the obstruction.The surface of the radar is dirty or obstructed.
Wait a short time. It may take several minutes for the radar to detectthat it is free from obstruction.The surface of the radar is clean but the message remains in thedisplay.
Do not use the system in these conditions because it may not detectany vehicles ahead.Heavy rain or snow is interfering with the radar signals.

Cruise ControlE253503

ActionCause
Do not use the system in these conditions because it may not detectany vehicles ahead.Water, snow or ice on the surface of the road may interfere with theradar signals.
Wait a short time or switch to normal cruise control.You are in a desert or remote area with no other vehicles and noroadside objects.
Contact an authorized dealer to have the radar checked for propercoverage and operation.Radar is out of alignment due to a front end impact.
Clean the outside of the windshield in front of the camera.The windshield in front of the camera is dirty or obstructed.
Wait a short time. It may take several minutes for the camera to detectthat it is free from obstruction.The windshield in front of the camera is clean, but the messageremains in the display.
Due to the nature of radar technology, it is possible to get a blockage warning with no actual block. This happens, for example, when drivingin sparse rural or desert environments. A false blocked condition either self clears, or clears after you restart your vehicle.
Switching to Normal Cruise Control
WARNING: Normal cruise control willnot brake when your vehicle isapproaching slower vehicles. Always beaware of which mode you have selectedand apply the brakes when necessary.
You can change from adaptive cruise controlto normal cruise control through theinformation display.
The cruise control indicator lightreplaces the adaptive cruisecontrol indicator light if you selectnormal cruise control. The gap setting doesnot display, and the system does not respondto lead vehicles. Automatic braking remainsactive to maintain set speed.
