GMC Terrain: Driving Information / Hill and Mountain Roads

Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips include:

  • Keep the vehicle serviced and in good shape.
  • Check all fluid levels and brakes, tires, cooling system, and transmission.
  • Shift to a lower gear when going down steep or long hills.

Warning

Using the brakes to slow the vehicle on a long downhill slope can cause brake overheating, can reduce brake performance, and could result in a loss of braking. Shift the transmission to a lower gear to let the engine assist the brakes on a steep downhill slope.

Warning

Coasting downhill in N (Neutral) or with the ignition off is dangerous. This can cause overheating of the brakes and loss of steering assist. Always have the engine running and the vehicle in gear.

  • Drive at speeds that keep the vehicle in its own lane. Do not swing wide or cross the center line.
  • Be alert on top of hills; something could be in your lane (e.g., stalled car, crash).
  • Pay attention to special road signs (e.g., falling rocks area, winding roads, long grades, passing or no-passing zones) and take appropriate action.
