Always switch thest ationary heater off
in enclosed spaces without an air
ex traction sy stems, e.g. in garage s. #
Keep theta ilpipe and the area around
th eve hicle free from snow when the
engine or thest ationary heater are run‐
ning. #
Open a window on the windward side of
th eve hicle toensure an adequate sup‐
ply of fresh air. &
WARNING Risk offire due tohot station‐
ary heater components and exhaust
ga ses
Flammable materials such as lea ves, grass or
twigs may ignite. #
When thest ationary heater is swit ched
on, make sure that:
R hot vehicle parts do not come into
contact with flammable materials.
R theex haust gas can flow out of the
st ationary heater exhaust pipe
unhindered.
R theex haust gas does not come into
contact with flammable materials. The heater
forth e auxiliary heating is fitted at the
front of theve hicle underbody. The emissions
outlet is on the left side of theve hicle below the
front door. &
WARNING Risk of poisoning duri ngwork
on the auxiliary warm-air hea ter
If wo rkon the heat exchanger of the auxiliary
wa rm-air hea ter is not per form ed cor rectl y,
ex haust fumes could leak into the passenger
compartment. #
Have all workon the auxiliary warm-air
hea ter car ried out at a qualified special‐

yo u are transpo rting hazardous materials, com‐
ply with there leva nt sa fety regulations. Place
objects a suf ficient dis tance from the auxiliary

The hot-water auxiliary heater is adjusted and
operated using the003B rock er switch on the cli‐

Obser vethe no tes on auxiliary heating
(/ page 126).
The hot-water auxiliary hea ter has a heater boos‐
te r,stationary heater and stationary ventilation
function. In addition, the auxiliary heating sy stem
heats the engine coolant toprotect the engine.
The stationary heater automatically adapts its
operating mode tochanges in outside temp era‐
ture and weather conditions. It is therefore possi‐
ble that thest ationary heater may swit chfrom
ve ntilation toheating mode or from heating to
ve ntilation mode.
The stationary heater will automatically swit ch
itself off af ter a maximum of 50 minutes. The
heater boos ter function helps toheat up theve hi‐
cle while the engine is running and at low outside
te mp eratures.
Yo u can set up tothre e departure times for pre-
entry clima tecontrol byremo tecontrol or via the
multimedia sy stem. The switch-on time is then
calculated based on the outside temp erature and
th e activated departure time. This means that
yo ur vehicle is preheated or precooled bythe set
departure time.
If th e departure time is reached and the engine is
not star ted, the auxiliary heating will continue to Climate cont

WARNING Risk of accident due toan
instrument clus ter malfunction
If th e instrument clus ter has failed or mal‐
functioned, you may not notice restrictions to
saf ety-re leva nt sy stem functions.
The operating saf ety of your vehicle may be
impaired. #
Drive on carefull y. #
Have theve hicle checked immediately
at a qualified specialist workshop. If
yo u are uncer tain rega rding the operational
saf ety of your vehicle, park theve hicle safely as
soon as possible. Inform a qualified specialist
wo rkshop.
The on-board computer will show only messages
and warnings from cer tain sy stems on the dis‐
pla y.Yo u should therefore make sure your vehicle
is operating safely at all times.

Speedome ter
In vehicles with Active Dis tance Assi st
DISTRONIC, there are illuminated segments on
th e speedome ter dial. These segments show
you what speed range is
av ailable:
R Variable limiter activated (/ page159)
The segments light up from thest art of the
scale tothe selected limit speed.
R Active Dis tance Assi stDISTRONIC switched
on (/ page 162)
One or two segments light up in the sa ved
speed range.
R Active Dis tance Assi stDISTRONIC de tects a
ve hicle in front.
The segments light up from the speed of the
ve hicle in front up tothe sa ved speed.
Yo u can show the speed as a digital speedome ter
on the display as well.
If yo uch ange your vehicle's wheel size, check its
assignment tothe wheel size group
(/ page 258). If the assignment changes with‐
out recoding the cont rol units in theve hicle, the
speedome ter will not display the speed accu‐
ra tely. The cur rent vehicle speed may then be
higher than the speed shown bythe speedome‐
te r.Driving and driving sa fety sy stems may then
be operationally impaired or may de tect a mal‐
function and switch themselves off.
In some count ries, an audible signal will sound
and/or a message will appear on the display
when theve hicle reaches the maximum speed
permitted bylaw, e.g. at 120 km/h.
