Recreational Vehicle Towing
If the vehicle has a two – mode hybrid engine, see the
Two – mode Hybrid manual for more information.
Recreational vehicle towing means towing the vehicle
behind another vehicle
– such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as dinghy towing and dolly towing.
Dinghy towing is towing the vehicle with all four wheels
on the ground. Dolly towing is towing the vehicle with
two wheels on the ground and two wheels up on a
device known as a dolly.
Here are some important things to consider before
recreational vehicle towing:
. What is the towing capacity of the towing vehicle?
Be sure to read the tow vehicle manufacturer's
recommendations.
. What is the distance that will be travelled? Some
vehicles have restrictions on how far and how long
they can tow.
. Is the proper towing equipment going to be used?
See your dealer or trailering professional for
additional advice and equipment
recommendations.
. Is the vehicle ready to be towed? Just as preparing
the vehicle for a long trip, make sure the vehicle is
prepared to be towed. See
Before Leaving on a
Long Trip on page 5 ‑ 27 .
Dinghy Towing
Two-Wheel-Drive Vehicles
Notice: If the vehicle is towed with all four wheels
on the ground, the drivetrain components could be
damaged. The repairs would not be covered by the
vehicle warranty. Do not tow the vehicle with all four
wheels on the ground.
Two-wheel-drive vehicles should not be towed with
all four wheels on the ground. Two-wheel-drive
transmissions have no provisions for internal lubrication
while being towed.
