HEATING/COOLING

AUXILIARY HEATER, FRONT

Water auxiliary
heater

Details and Technology

A fuel-powered 5 kW auxiliary heater is mounted under the floor in the area of the left hand B-pillar.
The auxiliary heater warms the coolant, which then heats the driver’s section via the water circuit of the
front end heater. The air is supplied to the interior via the air outlets in the instrument panel. The auxiliary
heater is programmed via the instrument cluster using the adjusting knobs (on vehicles with standard
instrument cluster) or the steering wheel buttons (on vehicles with multifunction steering wheel and pixel
matrix instrument cluster. Maximum operating time is 120 minutes, at which point the heater switches
off automatically. When the engine is running, the auxiliary heater can be turned on as a booster, using
the switch, to supplement the front end heater. When stationary heating mode terminates, the heater
automatically switches to booster mode.

Benefits and Arguments

Comfortably

warm

interior

• Aids defrosting of the windows
• Pre-heated coolant is kinder on the engine when starting
This system is particularly recommended for CRD-engined vehicles which will be used in very cold
climate regions. Since these engines have a very high efficiency, their thermal energy may not always be
sufficient, at extremely low ambient temperatures, to guarantee a comfortable level of warmth in the cab.
The stationary heating function allows the interior to be warmed even before the engine is started, so the
driver can step into a pleasantly warm vehicle right from the beginning.

Remarks

Auxiliary water heater is available on all models.
