Four-Wheel-Drive Vehicles
Use the following procedure to tow your vehicle from
the rear:
1. Drive the vehicle onto the dolly.
2. Firmly set the parking brake. See Parking Brake on
page 2-49 for more information.
3. Put an automatic transmission in PARK (P) or a
manual transmission in FIRST (1).
4. Follow the dolly manufacturer's instructions to
attach and secure the vehicle being towed to
the dolly and then the loaded dolly to the
tow vehicle.
For manual transmission vehicles, make sure the
wheels are straight before proceeding to the
next steps. On automatic transmission vehicles, use
an adequate clamping device to ensure that the
front wheels are locked into the straight position.
