GMC 2003 Envoy XL - Dinghy Towing; Four-Wheel-Drive Vehicles; Two-Wheel-Drive Vehicles

Dinghy Towing
When towing your vehicle, turn the ignition off.
To prevent your battery from draining while towing,
remove the Ignition
A and the Ignition B fuses from
the engine compartment fuse block. Be sure to reinstall
the fuse when you reach your destination.
Two-Wheel-Drive Vehicles
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. To properly tow these vehicles,
they should be placed
on a platform trailer.
In rare cases when it’s unavoidable that a
two-wheel-drive vehicle
is to be towed with all four
wheels on the ground, the propeller shaft
to axle yoke
orientation should be marked and the propeller shaft
removed following the applicable service manual
removal/installation procedure.
Dust or dirt can enter the back of the transmission
through the opening created by removing the propeller
shaft
if proper protection is not provided. Also, check
the transmission fluid level before driving the truck.
Four-Wheel-Drive Vehicles
Use the following procedure to tow your vehicle:
1. Firmly set the parking brake.
2. Shift the transmission to PARK (P).
3. Securely attach the vehicle being towed to the tow
vehicle.
