Access Height

Access height provides easier entry, exit and loading of the vehicle.

Access height can be selected at any vehicle speed. When access height is selected, the response of the air suspension system will depend on the vehicle speed:

• If the vehicle speed is more than 20 km/h (12.5 mph), the Chassis Control Module (CHCM) will wait for up to one minute for the vehicle speed to be reduced. The access mode indicator and the lowering indicator will flash while the CHCM waits for the vehicle speed to be reduced, the Normal height indicator will remain illuminated. If the vehicle speed is not reduced sufficiently, the access height request will be cancelled after a minute.
• If the vehicle speed is less than 20 km/h (12.5 mph), the CHCM will lower the suspension to a part lowered height and will remain at this height for up to one minute. The normal height indicator will extinguish as the CHCM lowers the suspension to the part lowered height. The access height indicator and the lowering indicator will illuminate. When part lowered is reached, the lowering indicator will flash. If the vehicle speed is not reduced to less than 8 km/h (5 mph) in the one minute period, the access height request will be cancelled.
• If the vehicle speed is less than 8 km/h (5 mph), the suspension will be lowered to access height immediately. The access height indicator and the lowering indicator will illuminate. When the access height is reached, the lowering indicator will be extinguished.

Access height may be selected up to 60 seconds after the ignition is turned off, provided that the driver's door has not been opened within this time.

The suspension will automatically rise from access height when the vehicle speed exceeds 7 km/h (4 mph) for 3 seconds or a speed of more than 15 km/h (9 mph).
