pedal immediately so that the vehicle does
not rol laway. DISTRONIC PLUS is then deac-
tivated, and the message disappears.
Tips for driving with DISTRONIC PLUS The following contains descriptions of certain
road and traf ficc ondition sinwhich you must
be particularly attentive. In such situations,
brake if necessary. DI STRONIC PLUS is then
deactivated. Cornering, going into and coming out of a
bend The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late.

Narrow vehicles DISTRONIC PLUS ha

Obstruction sand sta tionary vehicles DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns acorner and reveals
an obstacle or stationar yvehicle, DI STRONIC
PLUS will not brake for these. Crossin
gvehicles DISTRONIC PLUS may detect vehicles that
are crossing your lane by mistake. Activating
DISTRONIC PLUS at traffic lights with cross-
ing traffic, for example, could cause your vehi-
cle to pull away unintentionally.
SPEEDTRONIC
Important safety notes SPEEDTRONIC brakes automatically so that
you do not exceed the set speed
.Onlong and
steep downhil lgradients ,especially if the
vehicle is laden or towing atrailer, yo umust
shift to alower gear in good tim eorselect
shift range 1,2or 3on vehicles with auto-
matic transmission. By doing so, you will
mak euse of the brakin geffect of th eengine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly .Ifyou need addi-
tional braking, depress the brake pedal
repeatedly rather than con tinuously. G
Risk of accident
Never depress the brake pedal continuously
whil ethe vehicle is in motion, e.g. never cause
the brakes to ru bbyapplying constant slight
pedal pressure. This causes the brak esystem
to overheat, increases the braking distance
and can lead to the brakes failing completely. G
Risk of accident
Do not change down for additional engine
braking on aslippery road surface. This could Drivin
