Important safety notes

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 blocked filter replaced at a Mercedes- Benz Center as soon as possible.

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.

The automatic climate control adjusts the temperature and the humidity of the vehicle interior and filters undesired substances from the air.

The automatic climate control is only operational when the engine is running.15 Optimum operation is only achieved if you drive with the side windows and sliding sunroof/panorama roof with power tilt/ sliding panel closed.

Ventilate the vehicle for a brief period during warm weather, e.g. using the convenience opening feature (Y page 91).

This will speed up the cooling process and the desired vehicle interior temperature will be reached more quickly.

The integrated filter can filter out most particles of dust and completely filters out pollen. A clogged filter reduces the amount of air supplied to the vehicle interior. For this reason, you should always observe the interval for replacing the filter, which is specified in the Service Booklet. As it depends on environmental conditions, e.g.

heavy air pollution, the interval may be shorter than stated in the Service Booklet.

It is possible that the residual heat function may be activated automatically an hour after the SmartKey is removed. The vehicle is then ventilated for 30 minutes to dry the air-conditioning system.

Notes on using dual-zone automatic climate control

The following contains notes and recommendations on optimum use of dualzone automatic climate control.

 - Activate climate control using the and buttons. The indicator lamps above the and buttons light up.

 - Set the temperature to 72 °F (22 °C).

 - Only use the "defrosting" function briefly until the windshield is clear again.

 - Only use "air-recirculation" mode briefly, e.g. if there are unpleasant outside odors or when in a tunnel. The windows could otherwise fog up as, in air-recirculation mode, no fresh air is drawn into the vehicle.

 - Use the ZONE function to adopt the temperature settings on the driver's side for the front-passenger side as well. The indicator lamp above the button goes out.

Notes on using 3-zone automatic climate control

The following contains instructions and recommendations to enable you to get the most out of your automatic climate control.

 - Activate climate control using the and buttons. The indicator lamps above the and buttons light up. You can also set the airflow and air distribution of the automatic climate control to one of three levels (FOCUS/MEDIUM/DIFFUSE).

You can set the desired level using button 11. The MEDIUM level is recommended.

 - Set the temperature to 72 °F (22 °C).

 - Only use the "defrosting" function briefly until the windshield is clear again.

 - Only use "air-recirculation" mode briefly, e.g. if there are unpleasant outside odors or when in a tunnel. The windows could otherwise fog up as, in air-recirculation mode, no fresh air is drawn into the vehicle.

 - Use the ZONE function to adopt the temperature settings on the driver's side for the front-passenger side and the rear compartment as well. The indicator lamp above the button goes out.

 - Use the residual heat function if you want to heat or ventilate the vehicle interior when the ignition is switched off. The "residual heat" function can only be activated or deactivated with the ignition switched off.
