Driving while you tow
When towing a trailer:
• Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 km) of trailer towing and don’t make full-throttle starts.
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Use a lower gear to eliminate excessive shifting and assist in
transmission cooling. For additional information, refer to Automatic
transmission operation in the Driving chapter.
• Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.
