If towing your vehicle with a
wheel-lift type truck from the front,
the vehicle’s rear wheels and axles
must be in good conditions.
(  P.423, 421) If they are dam-
aged, use a towing dolly or flatbed
truck.
For AWD models: If towing your
vehicle with a wheel-lift type truck,
use a towing dolly. ( P.423, 421)

Failure to do so may result in death or
serious injury.
■When towing the vehicle
2WD models

WARNING
■While towing
●When towing using cables or chains,
avoid sudden starts, etc. which place
excessive stress on the towing eyelets,

cables or chains may become dam-
aged, broken debris may hit people,
and cause serious damage.
●Make sure to disable all functions of
the vehicle height control of the elec-
tronically modulate d air suspension.
Otherwise, the vehicle height may
change and part of your body may be
caught under the vehicle, possibly
causing injury. (

This may lead to an accident as the
rear wheels will be locked by the park-
