models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please not ethat your vehicle may not be
equipped with all feature sdescribed. This
also applies to safety-related system sand
functions.

anew vehicle Important safet
ynotes
New brake pads/linings only reach their opti-
mum brakin geffec tafter several hundred
kilometers of driving. Until that time, you may
need to use increased brake pedal pressure
while braking. This also applies after the
brake discs or the brake pads/linings have
been replaced. The first 1000 miles (1500 km)
The more you look after the engin ewhen it is
new, the more satisfied you will be with its
performanc einthe future.
R You should therefore drive at varying vehi-
cle and engin espeeds for the first
1,00 0miles (1,50 0km).
R Do not drive faster than 85 mph
(140 km/h) for the first 1,00 0miles
(1,50 0km).
R Only allow the engin etoreach amaximum
engin espeed of 4,50 0rpm briefly.
R Avoid heavy loads, e.g. drivin gatfull throt-
tle, during this period. Do not exceed 00C3of
the maximum permitted engin espeed for
each gear.
R Selec tthe manual drive program Min good
time. R
Do not carry out aRACE START.
R Do not manually shift to alower gear to
brake the vehicle.
R Try to avoid depressin gthe accelerator
pedal beyond the point of resistance (kick-
down).
R Only select the shift range limits 3,2or 1
when drivin gslowly, e.g. in mountainous
terrain.
After 1,00 0miles (1,500 km), you can
increase the engin espeed gradually and bring
the vehicle to full speed.

!
Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature. The oper-
ating temperature has been reached when
the engine oil temperature displayint he
on-board computer's AMG menu no longer flashes.
Only shift into reverse gear when the vehi-
cle is stationary.
Where possible, avoid spinning the drive
wheels when pulling awayons lippery
roads. You could otherwise damage the
drive train.
! During
acold start with low engine oil
temperatures (below 32 ‡) (0 †), the max- imum engine speed is restricted in order toprotect the engine. To protect the engine
and maintain smooth engine operation,
avoid driving at full throttle when the
engine is cold. Key positions
KEYLESS-GO start function You can switch the engine on and off with the

in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
If there is aSmartKey in the ignition lock, this

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
