Under special conditions, for example when driving in hilly terrain, extreme heat or with heavy loads, there is a risk that the engine and cooling system will overheat. Proceed as follows to avoid overheating the engine.

• Maintain a low speed when driving with a trailer up long, steep hills.
• Do not turn the engine off immediately when stopping after a hard drive.

WARNING

The cooling fan may start or continue to operate (for up to 6 minutes) after the engine has been switched off.

• Remove any auxiliary lights from in front of the grille when driving in hot weather conditions.
• Do not exceed engine speeds of 4500 rpm if driving with a trailer in hilly terrain. The oil temperature could become too high.
