Switching air-recirculation mode
on/off
General notes
You can also temporarily deactivate the flow offresh air manually if unpleasant odors are enter-ing the vehicle from outside. The air alreadyinside the vehicle will then be recirculated.
If you switch on air-recirculation mode, the win-dows can fog up more quickly, in particular atlow temperatures. Only use air-recirculationmode briefly to prevent the windows from fog-ging up.
Activating/deactivating
XTurn the SmartKey to positionHin the igni-tion lock (Ypage 131).
XTo activate:press therrocker switch upor down.The indicator lamp above therrockerswitch lights up.
Air-recirculation mode switches on automati-cally:

Driving and parking

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.
