Do not tow with a sling-type truck to
prevent body damage.
When using a flat-bed truck to
transport the vehicle, use tire
strapping belts. Refer to the

an emergency, your vehicle may
be temporarily towed using
cables or chains secured to the
emergency towing eyelets. This
should only be attempted on
hard surfaced roads for short
distances at under 18 mph (30
km/h).
A driver must be in the vehicle to
steer and operate the brakes.
The vehicle’s wheels, drive train,
axles, steering and brakes must
be in good condition.
To have your vehicle towed by
another vehicle, the towing eye-
let must be installed to your
vehicle. Install the towing eyelet
using the following procedure.
