TOWING THE VEHICLE BY A TOW TRUCK
.
This vehicle cannot be towed by a tow truck using
sling-type equipment (TYPE A) as illustrated; otherwise it
will damage the bumper and front end. If this vehicle is
towed, use wheel lift or flat bed equipment.
If the transmission is malfunctioning or damaged,
transport the vehicle with the driving wheels on a car-
riage (TYPE C, D or E) as illustrated.
If you tow the vehicles with an A/T with the driving
wheels on the ground (TYPE B) as illustrated, make
sure that the towing speed and distance given below
are never exceeded, causing damage to the transmis-
sion.
Towing speed: 50km/h
Towing distance: 30km
For the towing speed and the towing distance, follow
the local driving laws and regulations.
.
TOWING WITH FRONT WHEELS OFF THE
GROUND (TYPE C)
The vehicle may be towed on its rear wheels for extended dis-
tances provided the parking brake is released and gearshift
lever is in the "Neutral" position (M/T) or the selector lever is in
the "N" (NEUTRAL) position (A/T). It is recommended that vehi-
cles be towed using the front pickup whenever possible.
[For vehicles equipped with the traction control system
(TCL)]
If the vehicle is towed with the ignition key in the "ON"
position and only the front wheels or only the rear
wheels raised of the ground, a malfunction may occur
in the device
