When trouble arises
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive stress on the
emergency towing hook and the elastic towing rope. Always be cautious of the sur-
roundings and other vehicles while towing.
●Do not turn the engine switch off.
Doing so will lock the steerin g wheel and prevent operatio n, possibly causing an acci-
dent and resulting in death or serious injury.
●If the engine is not running, the power assi st for the brakes and steering will not func-
tion, making steering and braking more difficult.
