Brakes
Important safety notes
G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
G
WARNING
Make sure that other road users are not
endangered by your braking.
Downhill gradients
On long and steep downhill gradients, espe-
cially if the vehicle is laden, you must select
shift range 1, 2 or 3 in good time.
i
This also applies if you have activated
cruise control or SPEEDTRONIC.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Heavy and light loads
G WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the air-
flow to cool the brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet road surface
If driving in heavy rain for a prolonged period
of time without braking, there may be a
delayed reaction from the brakes when brak-
ing for the first time. This may also occur after
the vehicle has been washed.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehi-
cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm
up the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt-
treated roads
G WARNING
The layer of salt on the brake discs and the
brake pads/linings may cause a delay in the
braking effect, resulting in a significantly lon-
ger braking distance, which could lead to an
accident.
To avoid this danger, you should:
occasionally brake carefully, without put-
R
ting other road users at risk, when you are
driving on salted roads. This helps to
remove any salt that may have started to
build up on the brake discs and the brake
pads/linings.
maintain a greater distance to the vehicle
R
ahead and drive with particular care.
carefully apply the brakes at the end of a
R
trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake discs.
New brake pads/linings
G WARNING
New brake pads/linings only reach their opti-
mum braking effect after several hundred kil-
ometres of driving. Before this optimum brak-
ing effect is reached, you should compensate
