Always replace a fuse with one that has the specified
amperage rating. Using a fuse with a higher amperage
rating can cause severe wire damage and could start a
fire.
Driving While You Tow
Be especially careful when driving while you tow a trailer.
Never drive faster than 45 mph (70 km/h) when you tow in
hilly country on hot days. Also, anticipate stops so that you can
brake gradually.
If you use the speed control while you are towing on very long,
steep grades, the speed control may shut off automatically.
When descending a steep grade with a trailer, operate in Drive
rather than Overdrive. If additional braking is needed, shift into
2 (Second) or 1 (First) gear.
Servicing Your Vehicle If You Tow
If you tow a trailer for a long distance, your vehicle will need
to be serviced more frequently than usual. Refer to the
Maintenance Schedule booklet for additional information.
Trailer Towing Tips
Before starting on a trip, practice turning, stopping and backing
in an area away from heavy traffic. Get to know the "feel" of
the vehicle/trailer combination.
Practice backing up. Back up very slowly, with someone outside
at the rear of your trailer to guide you. Place your hand at the
bottom of the steering wheel and move it in the direction you
want the rear of the trailer to swing. Slight movement of the
steering wheel results in a much larger movement of the rear of
the trailer.
