- Unexpected adaptive cruise control braking
|
|
- The adaptive cruise control system can occasionally detect and respond to out-of-path vehicles, especially on curves, entry/exit ramps or when changing lanes. CHECK the C-CM
and front bumper cover for damage. RETEST the adaptive cruise control system.
|
- Lack of adaptive cruise control braking
|
|
- The adaptive cruise control system may not detect and respond to vehicles carrying out close cut-ins or on tight curves (especially for vehicles on the passenger side) due to limited C-CM
field of view. CHECK the C-CM
and front bumper cover for damage. If no damage is observed, RETEST the adaptive cruise control system.
|
- Noise during adaptive cruise control braking
|
|
- The driver can detect some noise at low speeds when adaptive cruise control braking occurs. This is normal operation. No repair is necessary.
|
- The cruise control cannot set speed above 128.7 kmh (80 mph)
|
- A MyKey® restricted key is in use and MyKey® max speed limiter is turned on
|
- VERIFY whether a MyKey® restricted key is in use. With an admin key, VERIFY if MyKey® max speed limiter is turned on. REFER to the Owner's Literature. If necessary, VERIFY cruise control normal operation with an admin key. REFER to the Owner's Literature.
