Off-road levels G Warning! Vehicle off-road level 3 is not intended for use on paved roads. This vehicle level is intended for clearing impracticable situations at low speed exclusively. The vehicle has a very high center of gravity in off-road level 3. This increases the overturning hazard. RSelect off-road level 3 exclusively for

clearing impracticable situations at low speed.

RAdapt your driving style to the modified

conditions.

RDo not exceed a speed of 12 mph

(20 km/h).

RAvoid extreme, quick steering

movements.

RKeep in mind the vehicle’s driving

characteristics are modified.

You should therefore drive in off-road level 3 with particular caution as it could otherwise lead to an accident and/or serious injury to you or others. If you are driving too fast while using off-road level 3, you will see the following message in the multifunction display: Reduce speed to under 12 MPH (20 km/h) In addition, an acoustic signal sounds. i This message cannot be deactivated.

Notes on climate control The climate control is operational whenever the engine is running. You can operate 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. Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system. G 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 Center. The air conditioning will not engage (no cooling) if the A/C mode is deactivated (Y page 206).

G Warning! Follow the recommended settings for heating and cooling given on the following pages. Otherwise the windows could fog up, impairing visibility and endangering you and others. Keep the air intake grille in front of the windshield free of snow and debris. i If the vehicle interior is hot, ventilate the

interior before driving off, see “Summer opening feature” (Y page 127). The climate control will then adjust the interior temperature to the set value much faster.

Deactivating the climate control system G Warning! When the climate control system is switched off, the outside air supply and circulation are also switched off. Only choose this setting for a short time. Otherwise the windows could fog up, impairing visibility and endangering you and others.

Follow the recommended settings for heating and cooling given on the following pages. Otherwise the windows could fog up, impairing visibility and endangering you and others. Keep the air intake grille in front of the windshield free of snow and debris. i If the vehicle interior is hot, ventilate the

interior before driving off, see “Summer opening feature” (Y page 127). The climate control will then adjust the interior temperature to the set value much faster.

Notes on 3-zone automatic climate control With the help of a sun sensor, the automatic climate control determines the relation of the sun to the vehicle and automatically adjusts the inside temperature for every individual zone. The automatic climate control is operational 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 temperature. 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. G 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
