Warning!

Power folding exterior rear view mirrors*

! Before you drive the vehicle through an automatic car wash, fold in the exterior rear view mirrors. Otherwise they may get damaged.

Folding the exterior rear view mirrors in and out automatically When the corresponding function in the control system is activated (컄 page 184): 앫 The exterior rear view mirrors automat- ically fold in as soon as the vehicle is locked from the outside.

앫 The exterior rear view mirrors automat- ically fold out as soon as the vehicle is unlocked and the driver’s or front pas- senger door are subsequently opened.

The auto-dimming function does not react if incoming light is not aimed directly at sen- sors in the interior rear view mirror.

The interior rear view mirror and the exterior rear view mirror on the driver’s side do not react, for example, when transporting cargo which covers the rear window.

Light hitting the mirror(s) at certain angles (incident light) could blind you. As a result, you may not be able to observe the traffic conditions and could cause an accident.

Warning!

Exercise care when using the passen- ger-side exterior rear view mirror. The mirror surface is convex (outwardly curved surface for a wider field of view). Objects in mirror are closer than they appear. Check your interior rear view mirror or glance over your shoulder before changing lanes.

204

Synchronizing exterior rear view mirrors The power folding rear view mirrors may have to be synchronized after the vehicle battery has been disconnected or discharged. If the exterior rear view mirrors do not fold properly upon locking or unlocking the vehicle although the corresponding function in the control system is activated (컄 page 184), do the following: 왘 Fold each exterior rear view mirror in

completely (컄 page 205).

왘 Fold each exterior rear view mirror out

completely (컄 page 205).

When the exterior rear view mirrors fold properly upon locking the vehicle, the exterior mirrors are synchronized. Otherwise repeat the above steps.

Folding the exterior rear view mirrors in and out manually

Folding in 왘 Briefly press button 1.

i The exterior rear view mirrors can vibrate if they are not folded out completely.

The button is located on the door control panel.

Controls in detail Good visibility

! With the sunshade raised and the respective door window open, the sunshade could disen- gage and snap back when driving at high vehicle speeds, e.g. on highways, and damage the retractor. You should therefore always either close the door window or lower the sunshade when driving at high speed.

Rear window defroster

The rear window defroster uses a large amount of power. To keep battery drain to a minimum, switch off the defroster as soon as the rear window is clear. The defroster is automatically deactivated after approximately 6 to 17 minutes of operation depending on the outside temperature.

Warning!

Any accumulation of snow and ice should be removed from the rear window before driv- ing. Visibility could otherwise be impaired, endangering you and others.

왘 Switch on the ignition (컄 page 39).

The climate control is operational when- ever the engine is running. You can oper- ate the climate control system in either the automatic or manual mode. The system cools or heats the interior depending on the selected interior temperature and the current outside temperature.

Warning!

When operating the climate control, the air that enters the passenger compartment through the air vents can be very hot or very cold (depending on the set temperature). This may cause burns or frostbite to unpro- tected skin in the immediate area of the air vents.

Always keep sufficient distance between un- protected parts of the body and the air vents. If necessary, use the air distribution controls (컄 page 210) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin.

Nearly all dust particles, pollutants and odors are filtered out before outside air en- ters the passenger compartment through the air distribution system.

Warning!

Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled replacement interval. A clogged filter will reduce the air volume to the interior and the windows could fog up, impairing visibility and endangering you and others. Have a clogged filter replaced as soon as possible at an authorized Mercedes-Benz Light Truck Center.

The air conditioning will not engage (no cooling) if the A/C mode is deactivated (컄 page 219).

Controls in detail Climate control

Warning!

Follow the recommended settings for heat- ing and cooling given on the following pag- es. Otherwise the windows could fog up, impairing visibility and endangering you and others.

i If the vehicle interior is hot, ventilate the in- terior before driving off, see “Summer opening feature” (컄 page 244). The climate control will then adjust the interior temperature to the set value much faster. Keep the air intake grille in front of the wind- shield free of snow and debris.

Warning!

When operating the automatic climate control, the air that enters the passenger compartment through the air vents can be very hot or very cold (depending on the set temperature). This may cause burns or frost- bite to unprotected skin in the immediate area of the air vents.

Always keep sufficient distance between unprotected parts of the body and the air vents. If necessary, use the air distribution controls (컄 page 224) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin.

The automatic climate control is a 3-zone intelligent automatic climate control system. Your vehicle interior is divided into 3 zones.

With the help of a sun sensor, the automatic climate control determines the relation of the sun to the vehicle and auto- matically adjusts the inside temperature for each individual zone.

Controls in detail 3-zone automatic climate control*

The automatic climate control is oper- ational whenever the engine is running. It cools the vehicle’s interior according to the angle and intensity of the sun’s rays, the outside temperature and the selected tem- perature. You can operate the automatic climate control in either the automatic or manual mode. Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system.

Warning!

Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled replacement interval. A clogged filter will reduce the air volume to the interior and the windows could fog up, impairing visibility and endangering you and others.
