Adaptive Cruise Control Operational Checks

Safety Considerations 

• The system can only apply limited braking. The driver's complete attention is always required while driving
• The system may not react to parked, stopped or slow-moving vehicles; the driver should always be ready to take action and apply the brakes
• Driver should not use adaptive cruise control on winding or hilly roads, on freeway exit or entrance ramps or when trailering. In these driving conditions, the system may not detect the vehicle ahead
• The system cannot detect traffic lights or traffic signs, so the driver needs to safely brake accordingly whenever approaching an intersection with a traffic light or stop sign
• If no vehicle ahead is detected, adaptive cruise control will work like regular cruise control
• When using adaptive cruise control, the driver should keep in mind that the system is designed to follow detected vehicles ahead at a longer distance when traveling at higher speeds than at lower speeds
• To avoid using adaptive cruise control by accident, advise customers to keep the cruise control button off when they don't need it. They should press the ON/OFF button and verify that the adaptive cruise control icon is not lit

Adaptive cruise control may have difficulty detecting the following objects:

• Vehicles in front of the driver's vehicle that have a rear aspect that is low, small or irregular
• A truck or trailer that has no cargo in the cargo bed
• Vehicles with cargo extending from the back end
• Non-standard shaped vehicles, such as vehicle transport, vehicles with a sidecar or horse carriages
• Vehicles that are low to the road surface
• Objects that are close to the front of the driver's vehicle

Weather conditions can affect adaptive cruise control:

• If the vehicle's interior temperature is extremely high, the P16 Instrument Panel Cluster Control Module may indicate that adaptive cruise control is temporarily unavailable. This can be caused by extreme hot weather conditions. Adaptive cruise control will return to normal operation once the ambient is cooler
• Conditions that are associated with low visibility, such as rain, snow or road spray, may limit the performance of adaptive cruise control.
