Driving on Slopes
Reduce speed and shift to a lower gear when starting to descend a long or steep slope. If you do not shift to a lower gear, you will need to brake more, and your brakes may overheat and fail to operate properly.
On long uphill grades, shift to a lower gear and reduce speed to approximately 70 km/h to reduce the risk of engine and transmission overheating.
If your trailer exceeds the maximum permissible weight without trailer brakes and your vehicle is equipped with an automatic transmission, set the shift lever to the D (Drive) position when towing a trailer.
This helps limit overheating and extends the service life of the transmission.
NOTICE
To prevent overheating of the engine and/or transmission:
- When towing a trailer on steep slopes (over 6%), carefully monitor the engine coolant temperature gauge to make sure the engine does not overheat. If the coolant temperature gauge needle approaches H (Hot), stop as soon as possible and allow the engine to cool. You may continue driving after the engine has cooled sufficiently.
- Adjust your driving speed to the trailer weight and the slope grade.
