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

Flammable materials such as lea ves, grass or
twigs may ignite. #
When thest ationary heater is swit ched

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

If yo ufa ilto adapt your driving style, 4MATIC can
neither reduce therisk of an accident nor over‐

account of road, weather and traf fic conditions.
4MATIC is only an aid. You are responsible espe‐
cially for maintaining a safe dis tance from the

R By activating the hazard warning lights
If th eve hicle is braked sharply from speeds
abo ve50 km/h, the brake lamps flash rapidl y.
This pr ovides traf fic tr ave lling behind you with an
eve n more noticeable warning.
If th eve hicle is tr avelling at speeds of more than
70 km/h at the beginning of the brake applica‐
tion, the hazard warning lights switch on once the
ve hicle is stationar y.When pulling away again,
th e hazard warning lights switch off automatically
at appr oximately 10km/h.
Yo u can also swit choff the hazard warning lights
using the hazard warning button (/ page107). Cruise control and limiter
Fu

Cruise cont rol accelerates and brakes theve hicle
automatically in order tomaintain a pr eviously
st ored speed.
If yo u accelerate toove rtake, forex ample, the
st ored speed is not dele ted. If youre mo veyour
fo ot from the accelerator pedal af terove rtaking,
cruise control will resume speed regulation back
to thestored speed.
Yo u operate cruise control using the cruise con‐
trol le ver.Yo u can store any speed abo ve
30 km/h.
Obser vethe no tes on driving sy stems and your
re sponsibility; you may otherwise failto recog‐
nise dangers (/ page 153). Sy
stem limits
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed if the uphill gradient evens out
and theve hicle's speed does not fall below
30 km/h.
On long and steep downhill gradients, you should
ch ange down toa lo werge ar in good time. Take
particular no teofthis when driving a laden vehi‐
cle. By doing so, you will make use of the
engine's braking ef fect. This will take some of the
st ra in off the brake sy stem and pr eventthe
brakes from overheating and wearing tooqu ickl y.
If yo uch ange wheel size on your vehicle, check it

( / page 258). If the category is changed without
re coding the cont rol units in theve hicle, the func‐

Do not use cruise control in thefo llowing situa‐
tions:
R in traf fic situations whe refrequent speed
ch anges are required, e.g. in heavy traf fic or
on winding roads
R off-road or on con stru ction sites
R on slippe ryor slick roads, as the drive wheels
can lose traction when accelerating and the
