Climate contro lregulates the temperature
and the humidity in the vehicle interior and
filter sundesirable substances out of the air.
Climate contro lisonly operational when the
engin eisrunning. Optimum operation is only
achieved when the side windows and the roof
are closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 167).
i Ventilate the vehicle for
abrief period
during warm weather, e.g. using the con-
venience openin gfeature (Y page 111).
This will speed up the coolin gprocess and
the desired interior temperature will be
reached more quickly. i
The integrated filter filter
sout most par-
ticles of dust and soot and completely fil-
ter sout pollen. It also reduces gaseous pol-
lutant sand odours. Aclogged filter reduces
the amount of air supplied to the vehicle
interior. For this reason ,you should always
observ ethe interval for replacin gthe filter,
which is specified in the Service Booklet. As this depends on environmental conditions,
e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30 minutes to dry the automatic climat econtrol. 156

Important safety notes G
WARNING
If yo ushift down on aslipper yroads urface in
an attempt to increas ethe engine's braking
effect, the drive wheels could lose thei rgrip.
Thi sincreases the ris kofskidding and having
an accident.
Do not shift down for additional engine brak-
ing on aslipper yroads urface.
Downhil lgradients Do not depress the brake peda
lcontinuously
whil ethe vehicl eisinmotion, e.g .never
cause the brakes to ru bbyconstantly apply-
ing light pressure to the pedal. Thi sresults in
excessive and premature wear to the brake
pads.
Chang einto alower gearing oodtime on long
and stee pdownhil lgradients.
Take particula rnote of thi swhend riving a
lade nvehicl eand when towing atrailer.
i Thi
salsoa pplies if youhavea ctivated
cruis econtrol, SPEEDTRONIC or
DISTRONIC PLUS.
Thi sw illu se the braking effect of the engine,
so less braking will be required to maintain
vehicl espeed .Thisr elieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Heavy and light loads G
WARNING
The braking system can overheat if yo ulea ve
your foo tonthe brake peda lwhile driving.
Thi sincreases the braking distance and could
eve ncause the braking system to fail. There is
ar iskofana ccident.
Never us ethe brake peda lasafootrest. Do
not simultaneousl ydepress both the brake
peda land the accelerato rpedal whiledriving. !
Depressing the brake peda
lconstantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to aheavy
load ,don ot stop the vehicl eimmediately, but
drive on for ashort while. Thi sallow sthe air-
flo wtoc ool the brakes more quickly.
If the brakes have been used onl ymoderately,

209Driving andparking Z

If you must drive on stretches of road on
which water has collected, please bear in
mind that:
R in the case of standing water, the water
level must be no highert han the loweredge
of the vehicle body
R you shouldd rive no faster than walking
pace Winter driving
G
WARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on aslippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle .This is the case, e.g. if the vehicle
becomes trapped in snow. There is arisk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not
facing into the wind.
Have yourv ehicle winterproofe dataqualified
specialist workshop at the onset of winter.
You shouldd rive particularly carefully on slip-
pery road surfaces .Avoid sudden accelera-
tion, steering and braking manoeuvres. If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission:
shift to neutral.
X Vehicles with automatic transmission:
shift the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
The outsid etemperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outsid etemperature are dis-
played after ashort delay.
Indicated temperature sjust above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areasoronb ridges. The
vehicle could skid if you fail to adapt your
driving style. Alwaysa dapt yourdriving style
and drive at aspeed to suit the prevailing
weather conditions.
You shouldp ay specialattention to road con-
ditions when temperature sare around freez-
ing point.
