Highway Exit Ramps {CAUTION: Adaptive Cruise Control may lose track of the vehicle ahead and accelerate up to your set speed while entering or on highway exit ramps. You could be startled by this acceleration and even lose control of the vehicle. Disengage Adaptive Cruise Control before entering a highway exit ramp. Do not use Adaptive Cruise Control while entering or on exit ramps. Adaptive Cruise Control may detect a vehicle that is not in your lane and apply the brakes. Adaptive Cruise Control may, occasionally, provide a driver alert and/or braking that you consider unnecessary. It could respond to signs, guardrails and other stationary objects when entering or exiting a curve. This is normal operation. Your vehicle does not need service. Other Vehicle Lane Changes If another vehicle enters the same lane as you, Adaptive Cruise Control will not detect the vehicle until it is completely in the lane. Be ready to take action and apply the brakes yourself. 3-29
