Get Climate control Guide for Mercedes GLE SUV Fourth Generation (2020-2026)

Overview of climate control systems

Notes on climate control

An interior lter in combination with the prelter

in the engine compartment must always be used

so that the air conditioning system, pollution level

monitoring and the air ltration work correctly.

Use lters recommended and approved by

Mercedes-Benz. Always have maintenance work

carried out at a qualied specialist workshop.

Stationary heater/ventilation

▌Stationary heater/ventilation function

The following function is equipment-depend-

ent.

The air inside the vehicle will be heated or ven-

tilated to the set temperature.

The air inside the vehicle cannot be cooled

down to temperatures below the outside tem-

perature.

If the outside temperature changes, ventilation

mode will automatically switch to heating

mode or heating mode will automatically

switch to ventilation mode.

The stationary heater and the exhaust gas outlet

are situated behind the right front wheel.

▌Switching the stationary heater/ventilation

on/o via the operating unit

DANGER Risk of fatal injury due to poison-

ous exhaust gases

If the tailpipe is blocked or sucient ventila-

tion is not possible, poisonous exhaust gases

such as carbon monoxide may enter the vehi-

cle. This is the case in enclosed spaces or if

the vehicle gets stuck in snow, for example.

Always switch the stationary heater o in

enclosed spaces without an air extrac-

tion system, e.g. in garages.

Keep the tailpipe and the area around

the vehicle free from snow when the

engine or the stationary heater is run-

ning.

Open a window on the side of the vehicle

facing away from the wind to ensure an

adequate supply of fresh air.

Flammable materials such as leaves, grass or

twigs may ignite.

When the stationary heater is switched

on, make sure that:

hot vehicle parts do not come into

contact with ammable materials.

the exhaust gas can ow out of the

stationary heater exhaust pipe unhin-

dered.

the exhaust gas does not come into

contact with ammable materials.
