Dolly Towing
Front Towing (Front Wheels Off
the Ground) – Two-Wheel-Drive
Vehicles
Notice: If a two-wheel drive
vehicle is towed with the rear
wheels on the ground, the
transmission could be damaged.
The repairs would not be covered
by the vehicle warranty. Never
tow the vehicle with the rear
wheels on the ground.
Two-wheel-drive vehicles should
not be towed with the rear wheels
on the ground. Two-wheel-drive
transmissions have no provisions
for internal lubrication while being
towed.
To dolly tow a two‐wheel‐drive
vehicle, the vehicle must be towed
with the rear wheels on the dolly.
See “Rear Towing (Rear Wheels Off
the Ground)” later in this section for
more information.
