If you shift down onaslippery roadsurface in
an attempt toincrease theengine's braking
effect ,the drive wheels couldlosetheir grip.
There isan increased dangerofskidding and
accident s.
Do not shift down foradditional enginebrak-
ing onaslippery roadsurface.
Dow nhill gradients !
On
long andsteep gradients, youmust
reduce theload onthe brakes byshiftin gto a

take advantage ofengine braking. Forthis you

helps
youtoavoid overheating thebrakes and
wearing themoutexcessively.
When youtake advantage ofengine braking, it
is possible thatadrive wheel willnotrotate for
some time,e.g.onaslippery roadsurface.
This could cause damage tothe drive train.
This type ofdamage isnot covered bythe
Mercedes-Ben zwarranty.

WARNING
If you rest your footonthe brake pedalwhile
driving, thebraking systemcanoverheat. This
increases thestopping distanceandcaneven
cause thebraking systemtofail. There isa
risk ofan accident.
Never usethebrake pedalasafootrest .Never
depress thebrake pedalandtheaccelerator
pedal atthe same time.
! Depressing
thebrake pedalconstantly
results inexcessive andpremature wearto
the brake pads.
If the brakes havebeen subjected toaheavy
load, donot stop thevehicle immediately. Drive
on for ashort while. Thisallow sthe airflow to
cool thebrakes morequickly.
Wet roads If
you have driven foralong time inheavy rain
without braking, theremaybeadelay edreac-
tion from thebrakes whenbraking forthe first
time. Thismay alsooccur afterthevehicle has
been washed ordriven through deepwater.
You have todepress thebrake pedalmore
firmly. Maintain agreater distance fromthe
