TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service. If the trans-
mission and drivetrain are operable, disabled vehicles
may also be towed as described under “Recreational
Towing” in the “Starting And Operating” section.NOTE:
Vehicles equipped with air suspension must be
placed in Transport mode, before tying them down (from
the body) on a trailer or flatbed truck. Refer to Air
Suspension inStarting And Operating for more infor-
mation. If the vehicle cannot be placed in Transport mode
(for example, engine will not run), tie-downs must be
fastened to the axles (not to the body). Failure to follow
these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.
