REAR SUSPENSION

DESCRIPTION AND OPERATION

64-23

Transportation mode
Transportation mode must be used when the vehicle is transported on a trailer and secured by the chassis. The 
transportation mode can only be enabled and disabled with TestBook.

The transportation mode lowers the rear suspension onto the bump stops with the engine not running. When the 
suspension is in transportation mode, the SLS warning lamp is continuously illuminated when the ignition is in position 
II.

When the engine is started in transportation mode, the SLS system will raise the rear suspension until a gap of 25 
mm (1 in.) exists between the bump stop and the axle. The SLS warning lamp will flash continuously while the SLS 
system is raising the suspension. When the gap between the bump stop and the axle is achieved, the warning lamp 
will illuminate continuously.

When TestBook is used to disable the transportation mode, the rear suspension will raise to normal ride height when 
the engine is running.
