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 your vehicle has a manual transaxle and you are towing a trailer, you should select gear positions which will avoid jerking or excessive engine speed. If you need to drive excessively in 1 (First) or 2 (Second), it may indicate that the trailer is too big or heavily loaded for your vehicle's drivetrain. Continuous driving in these two gears while towing a trailer is not recommended. When you tow up or down steep hills, move the manual transaxle gearshift to a lower gear. This will increase engine power on upgrades and engine braking on downgrades. When you tow in steep hills, move the automatic transaxle to 1 (First) when descending. This will give more engine braking on downgrades. The automatic transaxle will automatically downshift to the proper gear on upgrades. If you use the speed control while you are towing on very long, steep grades, the speed control may shut off. 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 and Record booklet for additional information. 158
