10-84 Vehicle Care
Two-wheel-drive vehicles should not
be towed with all four wheels on the
ground.
Four-Wheel-Drive Vehicles
Only dinghy tow four-wheel-drive
vehicles with a two-speed transfer
case that have an N (Neutral) and a
Four-Wheel Drive Low (4 ) setting.
Warning
Shifting a four-wheel-drive
vehicle's transfer case into
N (Neutral) can cause the vehicle
to roll even if the transmission is
in P (Park). You or others could
be injured. Set the parking brake
before shifting the transfer case
to N (Neutral).
Follow these steps to dinghy tow:
1. Position the vehicle being towed
behind the tow vehicle, facing
forward and on a level surface.
2. Securely attach the vehicle
being towed to the tow vehicle.
3. Apply the parking brake and
start the engine.
For vehicles with electric parking
brakes, the parking brake cannot
be applied and the tires must be
chocked.
4. Shift the transfer case to
N (Neutral). See Shifting into
N (Neutral) under Four-Wheel
Drive on page 9-37 for the
proper procedure. Check that
the vehicle is in N (Neutral) by
shifting the transmission to
R (Reverse) and then to
D (Drive). There should be no
movement of the vehicle while
shifting.
5. With the transmission in
D (Drive), turn the ignition to
ACC/ACCESSORY. Vehicles
with Keyless Access, turn the
engine off.

battery cable or to have it contact
the terminals can cause damage
