The wear of individual componentsoft
he
brake system, such as the brake pads/linings
or brake discs, depends on the individual driv-
ing style and operating conditions.
For this reason, it is impossible to state a
mileage lifetime that will be valid under all
circumstances. An aggressive driving style
will lead to high wear. You can obtain further
information about this from your Mercedes-
Benz Servic eCentre.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometres of driving. Compen-
sate for this by applying greater force to the
brake pedal. Do not forget this, and adapt
your driving and braking accordingly during
this run-in period.
Excessively heavy braking results in corre-
spondingly high brake wear. Observe the
brake system warning lamp in the instrument
cluster and notea ny brake status messages
in the multifunction display .For high-per-
formanc edriving in particular, it is important
to maintain and have the brake system
checked regularly. Driving on wet roads
Aquaplaning If water has accumulated to
acertain depth
on the road surface, there is adanger of aqua-
planing occurring, even if:
R you are driving at low speeds.
R the tyres have adequate tread depth.
For this reason, do not drive in tyre ruts and
brake carefully.
Driving on flooded roads !
Bear in mind that vehicles travelling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
These notes must be observed under all
circumstances. You could otherwise dam- age the engine, the electronics or the trans-
mission.
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R the maximum permissible still water depth
is 25 cm.
R you should drive no faster than at walking
pace. Winter driving
Important safety notes 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
aw indow on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at aqualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation"
section (Y page 330).
Driving with summer tyres Observe the notes in the "Winter operation"
section (Y
