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

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.
