th e road surface, there is a danger of hydro-
planin g occurring, eve n if:R
you drive at low speeds .R
th e tires hav e adequat e tread depth.
Fo r this reason , in th e event of heav y rain or in
condition s in whic h hydroplaning may occur ,

G WARNING
If you shift down on a slipper y road surfac e in
an attempt to increase th e engine's braking
effect , th e drive wheels could los e their grip.
There is an increase d danger of skidding and
accidents .
Do no t shift down fo r additional engin e brak-
in g on a slipper y road surface.
G DANGER
If th e exhaus t pipe is blocke d or adequat e
ventilation is no t possible, poisonous gases
suc h as carbon monoxide (CO) may ente r th e
vehicle. Thi s is th e case, e.g. if th e vehicle
becomes trappe d in snow. There is a ris k of
fatal injury. If you leav e th e engin e or th e auxiliar y heatin g

facin g into th e wind.
Hav e your vehicle winter-proofed at a qualified
specialis t workshop at th e onset of winter.
Drive particularly carefully on slipper y road sur -
faces. Avoid sudden acceleration , steerin g and
braking maneuvers . Do no t use th e cruise con-
trol or DISTRONIC PLUS.
If th e vehicle threatens to skid or canno t be
stopped when movin g at low speed:X
Shift th e transmissio n to position N .
The outsid e temperature indicator is no t
designed to serve as an ice-warnin g devic e and
is therefore unsuitable fo r that purpose.
Changes in th e outsid e temperature are dis -
playe d after a short delay.
Indicated temperature s just abov e th e freezin g
poin t do no t guarantee that th e road surfac e is
free of ice. The road may still be icy, especially in
wooded areas or on bridges. The vehicle could
skid if you fail to adapt your drivin g style. Always
adapt your drivin g style and drive at a speed to
suit th e prevailin g w eather conditions.
You should pay special attention to road condi-
tion s when temperature s are around freezin g
point.
