Lane Keeping System

WARNING:  You are responsible for controlling your vehicle at all times. The system is designed to be an aid and does not relieve you of your responsibility to drive with due care and attention. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.    WARNING:  The system may not function if the sensor is blocked.    WARNING:  The sensor may incorrectly track lane markings as other structures or objects. This can result in a false or missed warning.    WARNING:  In cold and severe weather conditions the system may not function. Rain, snow and spray can all limit sensor performance.    WARNING:  Large contrasts in outside lighting can limit sensor performance.    WARNING:  The system will not operate if the sensor cannot track the road lane markings.    WARNING:  If damage occurs in the immediate area surrounding the sensor, have your vehicle checked as soon as possible.    WARNING:  The system may not correctly operate if your vehicle is fitted with a suspension kit not approved by us.

The system is designed to alert you by providing a temporary steering torque input or steering wheel vibration when it detects an unintended lane departure.  The system detects and tracks the road lane markings using a camera mounted behind the interior mirror.The system only operates when the vehicle speed is greater than approximately 65 km/h (40 mph).You can view the system status in the instrument cluster.

Note:   The system works when the camera can detect at least one lane marking.

• You apply direct steering, accelerate fast or brake hard.
• The vehicle speed is less than 65 km/h (40 mph).
• The anti-lock brake, stability control or traction control system activates.
