eral hundred kilometers ofdriving. Compen-
sate forthis byappl ying greater forcetothe
brake pedal.Keep thisinmind, andadaptyou r
driving andbraking accordingly duringthis
break-in period.
Excessive heavybraking resultsincorrespond-
ingly highbrake wear.Observe thebrake sys-
tem warning lampinthe instrument cluster
and note anybrake status message sin the
multifu nctiondisplay.Especiall yfor high per-
formance driving,itis important tomaintain
and have thebrake system checked regularly. Drivin
gon wet roads
Hydroplaning If
water hasaccumul atedtoacertain depthon
the road surface, thereisadanger ofhydro-
planing occurring.
For this reason, inthe event ofheavy rainorin
conditions inwhich hydrop laningmayoccur,
you must driveinthe follow ingmanner:
R lowe ryou rspeed
R avoid ruts
R avoid sudde nsteering movements
R brake careful ly
Drivin gon floo ded roads !
Do
not drive through floodedareas.Check
the depth ofany water before driving
through it.Drive slowlythrough standing
water. Otherwise, watercouldenterthe
vehicle interior orengine compartment. It
can then dama gethe engine's orautoma tic
transmission's electroniccomponents. It
can also besucked inby the engine's air

WARNING
If you shift down onaslipp eryroad surface
in an attempt toincrease theengine's brak-
ing effect, thedrive wheel scould losetheir grip.
There isan increased dangerofskid-
ding andaccidents.
Do not shift down foraddi tional engine brak-
ing onaslipp eryroad surface. G
DANGER
If the exhaust pipeisblocked oradeq uate
ventilation isnot possib le,poisonou sgases
such ascarbon monoxide (CO)mayenter
the vehicle. Thisisthe case, e.g.ifthe vehi-
cle becomes trappedinsnow. Thereisarisk
of fatal injury.
If you leave theengine orthe auxil iaryheat-
ing running, makesuretheexhaust pipeand
area around thevehicle areclear ofsnow.
To ensure anadeq uate suppl yof fresh air,
open awindow onthe side ofthe vehicle
that isnot facing intothewind.
Have yourvehicle winter-proofed ataqua lified

Drive particul arlycareful lyon slipp eryroad
surfaces. Avoidsuddenaccelera tion,steering
and braking maneuvers. Donot use cruise
control.
If the vehicle threatens toskid orcannot be
stopped whenmoving atlow speed:
X Shift thetransmission toposition 005C.
The outside temperature indicatorisnot
designed toserve asan ice-warning device
and istherefore unsuitable forthat purpos e.
