Operation
Driving tips
G Risk of accident
New brake pads/linings only reach their
optimum braking effect after several hun-
dred kilometres of driving. Before this opti-
mum braking effect is reached, you should
compensate for the reduced braking effect
by applying greater pressure when braking.
This also applies after the brake discs or the
brake pads/linings have been replaced.
High-performance brake system for
AMG vehicles
The high-performance brake system is
designed for heavy loads. Braking can there-
fore cause noises. This will depend on:
speed
R
braking force
R
environmental conditions, such as temper-
R
ature and humidity
The wear of individual components of the
brake system, such as the brake pads/linings
or brake discs, depends on the individual driv-
ing style and operating conditions.
Because of this, it is impossible to state a
mileage that will be valid under all circum-
234
stances. An aggressive driving style will lead
to high wear.
Tyre grip
G Risk of accident
Whereas the vehicle can be fully controlled
at a certain speed on dry roads, you must
reduce your speed on wet or icy roads to
achieve the same road safety. Otherwise
you could cause an accident.
Pay particular attention to the road condi-
tions at temperatures around freezing
point.
If ice has formed on the road surface (e.g.
from fog), a light film of water rapidly forms
on the ice when you brake, considerably
reducing tyre grip. Drive with particular
care in such weather conditions.
Driving on wet roads
If water has accumulated to a certain depth
on the road surface, there is a danger of aqua-
planing occurring, even if:
you drive at low speeds
R
the tyres have adequate tread depth
R
For this reason, do not drive in tyre ruts, and
brake carefully.
Driving on flooded roads
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
the maximum permitted still water depth is
R
25 cm
you should drive no faster than at walking
R
pace
!
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.
You must observe these notes, otherwise
damage may occur to the engine, electrics
and transmission.
