336 Emergency Information
WARNING
Do not tow a vehicle backwards when
equipped with roof air fairings. The fair-
ings act as an air scoop and may break
off. Failure to follow this warning may
lead to personal injury and vehicle dam-
age.
WARNING
Vehicles with air fairings are tall. Make
sure that the total height of the vehicle,
when it is raised up behind the wrecker,
does not exceed the maximum allowed
height for local underpasses. Failure to
follow this instruction may lead to per-
sonal injury and vehicle damage.
The vehicle may now be towed. It is rec-
ommended that a wrecker with a lift bar is
used since the service brakes will not func-
tion. The system must be filled with air to
release the parking brake or follow the me-
chanical spring brake caging procedures on
page 339.
NOTE! The power steering does not func-
tion when towing a vehicle with a disabled
engine.
