Four-Wheel Drive Vehicles
The manufacturer recommends towing with all wheels
OFF
the ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of the vehicle raised
and the opposite end on a towing dolly.
Two-Wheel Drive Vehicles
Provided that the transmission is operable, tow with the
transmission in NEUTRAL and the ignition key in the
OFF position, along with the front wheels raised and the
rear wheels on the ground. The speed must not exceed 30
mph (50 km/h), and the distance must not exceed 15 mi
(25 km).
If the vehicle is to be towed more than 15 mi (25 km) or
faster than 30 mph (50 km/h), it must be towed on a
flatbed, or with the rear wheels raised and the front
wheels on the ground, or with the front end raised and
the rear wheels on a towing dolly.
NOTE: Towing the vehicle with the rear wheels on the
ground at more than 30 mph (50 km/h) or for more than
15 mi (25 km), can cause severe transmission damage.
