vehicle location outside the vehicle for
certain purposes. Even if the Location
Services setting is disabled, vehicle location

glass cleaner. Wipe the lens gently, then dry
it. Never use abrasive cloths/cleaners or
corrosive chemicals of any kind on the lens
cover.

camera, and 360 degree cameras for its
operation. Clean surfaces are required for
Super Cruise operation. SeeAdaptive Cruise
Control (Advanced) 0196, “Surround Vision
Camera” underAdvanced Driver Assistance
Systems 0223, and Lane Keep Assist (LKA)

serviced by technicians with the proper
training, tools, and safety instructions,
which your dealer has. Without proper
training and tools the vehicle may
become damaged.
