Driving while you tow
When towing a trailer:
• To ensure proper “break-in” of powertrain components, do not trailer
tow during the first 1,000 miles (1600 km) of a new vehicle.
• To ensure proper “break-in” of powertrain components during the first
500 miles (800 km) of trailer towing, drive no faster than 70 mph (112
km/h) with no full throttle starts.
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Consult your local motor vehicle speed regulations for towing a trailer.
• To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with a 5–speed automatic transmission section in the
Driving chapter.)
