When overtaking, pay particular attention to theextended length of your vehicle/trailer combi-nation.
Due to the length of the vehicle/trailer combi-nation, you require additional road space whenovertaking before you can change back to theoriginal lane.
If the automatic transmission repeatedly shiftsbetween gears on uphill or downhill gradients,shift to a lower gear.
Driving in a lower gear and at a reduced speeddecreases the risk of engine damage.
If the coolant temperature increases signifi-cantly when climate control is switched on,switch climate control off.
Coolant heat can also be dissipated by openingthe windows and switching the ventilationblower and the interior temperature to the high-est level.
