Dinghy Towing from the Front
(2.0L Engine with Automatic
Transmission)
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.
Vehicles with the 2.0L engine and
an automatic transmission should
not be towed with all four wheels on
the ground.
Dinghy Towing from the Front
(Except 2.0L Engine with
Automatic Transmission)
When dinghy towing a vehicle with
an automatic transmission, the
vehicle should be run at the
beginning of each day and at each
RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components.
Use the following procedure to
dinghy tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle being towed
behind the tow vehicle.
2. Shift the automatic transmission
to P (Park) or a manual
transmission into 1 (First) gear
and turn the engine off.
3. Set the parking brake.
4. Following the manufacturer's
instructions, attach the vehicle
being towed to the tow vehicle.
5. Shift the automatic transmission
to N (Neutral) or a manual
transmission into Neutral.
6. Release the parking brake.
When towing the vehicle for
extended periods of time, start the
vehicle as often as possible to
prevent battery drain. This should
be done when the tow vehicle is
parked.
