Vehicle Care 319
The vehicle is equipped with a tow eye.
Only use the tow eye to pull the vehicle
onto a flatbed car carrier from a flat road
surface. Do not use the tow eye to pull the
vehicle from snow, mud, or sand.
The tow eye is stored underneath the load
floor, near the spare tire or the compressor
kit, if equipped.
Front Tow Eye
Carefully open the cover by using the small
notch that conceals the front tow eye
socket.
Install the tow eye into the socket and turn
it until it is fully tightened.
When the tow eye is removed, reinstall the
cover with the notch in the original position.
Rear Tow Eye
If the vehicle is equipped with a hitch, there
is no provision to use the tow eye in the
rear of the vehicle. The hitch may be used
to load the vehicle onto a flatbed tow truck.
If equipped, carefully open the cover by
using the small notch that conceals the rear
tow eye socket.
