GCWR (Gross Combined Weight Rating)/Trailer Weights
Engine
GCWR - lb.
2.3L 5180 (2350)
3.0L 7260 (3293)
Notes: For high altitude operation, reduce GCW by 2% per 1,000 ft.
(300 meters) elevation. For definitions of terms and instructions on
calculating your vehicle's load, refer to Vehicle Loading in this
chapter. Maximum trailer weights shown. The combined weight of the
completed towing vehicle and the loaded trailer must not exceed the
GCWR.
The Mariner is capable of pulling the maximum trailer weight(s) as
specified above. Certain states require electric trailer brakes for trailers
over a specified weight. The Mariner vehicle electrical system is not
equipped to accommodate electric trailer brakes.
Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of vehicle
control, vehicle rollover and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your authorized dealer or a
reliable trailer dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch. You must distribute the load in your trailer so that
10–15% of the total weight of the trailer is on the tongue.
