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 this chapter. • Under extreme conditions with large frontal trailers, high outside temperatures and highway speeds, the coolant gauge may indicate higher than normal coolant temperatures. If this occurs, reduce speed until the coolant temperature returns to the normal range. Refer to Engine coolant temperature gauge in the Instrument cluster chapter. • Anticipate stops and brake gradually. • Do not exceed the GCWR rating or transmission damage may occur. Servicing after towing If you tow a trailer for long distances, your vehicle will require more frequent service intervals. Refer to your scheduled maintenance guide for more information. 145
