lutant sand odors. Aclogged filter reduces
the amount of air supplied to the vehicle
interior. For this reason ,you should always
observ ethe interval for replacin gthe filter,
which is specified in the Maintenance
Booklet. As it depends on environmental
conditions, e.g. heavy air pollution, the
interval may be shorter than stated in the

Wet roads
If you have drive
nfor along time in heavy rain
without braking, there may be adelayed reac-
tion from the brakes whe nbraking for the first
time. This may also occur after the vehicl ehas
been washed or drive nthroug hdeep water.
You have to depress the brake pedal more
firmly .Maintain agreater distance from the
vehicl einfront.
After driving on awet road or having the vehi-
cle washed ,brake firmly while paying atten-
tion to the traffic conditions. This wil lwarmup
the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt-
treated roads If you drive on salted roads,
alayer of salt
residue may form on the brake discs and
brake pads. This can result in asignificantly
longe rbraking distance.
R Brake occasionally to remove any possible
sal tresidue. Make sure that you do not
endange rother road users whe ndoing so.
R Carefully depress the brake pedal and the
beginning and end of ajourney.
R Maintain agreater distance to the vehicle
ahead.
Servicing the brakes !
If the red brake warning lamp lights up in
the instrument cluster and you hea rawarn-
ing tone while the engine is running, the
brake fluid leve lmay be too low .Observe
additiona lwarning messages in the multi-
function display.
The brake fluid leve lmay be too low due to
brake pad wea rorleaking brake lines.
Have the brake syste mchecked immedi-
ately. This work should be carrie dout at a
qualified specialist workshop. !
As the ESP ®
syste moperates automati-
cally, the engine and the ignition must be
switched off (the SmartKey must be in posi-
tion 0or 1in the ignition lock or the Start/
Stop button must be in position 0or 1)i f:
R the electric parking brake is tested using
ab rake dynamometer.
R the vehicl eistowed with one axle raised.
Braking triggered automatically by ESP ®
may seriousl ydamage the brake system.
All checks and maintenance work on the
brake syste mmust be carrie dout at aquali-
fied specialist workshop. Have this work car- ried out at an authorized Mercedes-Benz
Center.
Have the brake pad sreplaced and the brake
fluid renewe dataqualified specialist work-
shop, e.g. an authorized Mercedes-Benz
Center.
If the brake syste mhas only been subject to
moderate loads, you should test the function- ality of you rbrakes at regulari ntervals. At a
high speed, brake firmly while paying atten-
tion to the traffic conditions. This improves
the grip of the brake pads.
You can find adescription of Brake Assist
(BAS) on (Y page55).
Mercedes-Benz recommends that you only
have brake pads/linings installed on your
vehicl ewhich have been approved for
Mercedes-Benz vehicles or which correspond to an equivalent quality standard. Brake
pads/linings which have not been approved
for Mercedes-Benz vehicles or which are not
of an equivalent quality coul daffect you rvehi-
cle's operating safety.
