R brakepads, brake discs and tyres that are
either new or ha vebeen replaced only ach‐

WARNING Risk of accident due to
objects in the driver's foot we ll
Objects in the driver's foot we ll may impede
pedal tra vel or block a depressed pedal.
This jeopardises the operating and road
saf ety of theve hicle. #
Stow all objects in theve hicle securely
so that they cannot getinto the driver's
fo ot we ll. #
Alw aysfit th efloor mats securely and
as prescribed in order toensure that th
ere is alw ays suf ficient room forthe
pedals. #
Do not use loose floor mats and do not
place floor mats on top of one ano ther. &
WARNING Risk of accident due to
unsuitable foot we ar
Operating the pedals may be impaired by
we aring unsuitable foot we ar, e.g.:
R plat form shoes
R high-heeled shoes
R slippers #
Alw ayswe ar suitable foot we ar when
driving so that you can operate the ped‐
als safel y. &
WARNING Risk of accident when switch‐
ing off the ignition when driving
If yo u swit choff the ignition while driving,
saf ety functions are restricted or no longer
av ailable. This may af fect the po werst eering sy
stem and the brake forc e boosting, for
ex ample.
Yo u will then need touse considerably more
fo rc eto steer and brake. #
Do not switch off the ignition while driv‐
ing. &
DANG ER Risk of fata l injuries due to
ex haust gases
Combustion engines emit poisonous exhaust
ga ses such as carbon monoxide. Inhaling
th ese exhaust gases is hazardous tohealth
and can lead topoisoning. #
Never lea vethe engine running in an
enclosed space wi thout suf ficient venti‐
lation. &
WARNING Risk of skidding and of an
accident due toshifting down on slippery
ro ad sur faces
If yo u shift down on slippery road sur faces to
inc rease the engine braking ef fect, the drive
wheels may lose traction. Driving and parking

WARNING Risk of accident due toincor‐
re ct gearshifting
If th e engine speed is higher than the idle
speed and you en gage the transmission posi‐
tion hork, theve hicle may accelerate
sharply. #
Ifyo u en gage the transmission position
h ork always depress the brake
pedal firm lyand do not accelerate at
th e same time. Limited braking ef
fect on salt-trea tedro ads:
R due tosalt build-up on the brake disks and
brakepads, the braking dis tance can increase
conside rably or result in braking only on one
side
R maintain a much greater safe dis tance tothe
ve hicle in front
To remo vethe la yer of salt:
R brake occasionally while paying attention to
th e tra ffic conditions R
carefully depress the brake pedal at the end
of the journey and when starting the next
journey Fu
nction of rear axle steering Depending on
the speed, rear axle steering
adapts the tra ckofthere ar axle tothe position
of the front wheels. Toge ther with thesteering
input of the front wheels, this results in greater
mobility and impr ovedstabilit y.
Re ar axle steering has thefo llowing characteris‐
tics:
R reduced steering ef fort and turning circle
re sulting in reduced parking ef fort
R impr oved driving stabilit y,e.g. on cur ves
R more direct steering resulting in impr oved
control of theve hicle Tips
for the AMG ce ramic high-pe rformance
composite brake sy stem The brake sy
stem is designed for heavy loads.
This may lead tonoise when braking. This ef fect
can also occur af terwa shing theve hicle.
The noise depends on thefo llowing factors:
R speed
R brake force
R environmen tal conditions, e.g. temp erature
and air humidity
% Have the brake sy stem checked at a quali‐
fi ed specialist workshop af ter it has been
subjected toextreme loads. Driving and pa

WARNING Risk of entrapment if the
windscreen wipers are swit ched on while
th e windscreen is being cleaned
If th e windscreen wipers are set in motion
while you are cleaning the windscreen or
wiper blades, you can be trapped bythe
wiper arm. #
Alw ays switch off the windscreen wip‐
ers and the ignition before cleaning the

WARNING Risk of bu rning from theta il‐
pipe or tailpipe trim
The tailpipe and tailpipe trim can become
ve ry hot. If you come into contact with these
car parts, you could burn yourself. #
Alw ays be particular lycareful when in
th e vicinity of theta ilpipe and tailpipe
trims and supervise children very
closely when in this area. #
Before any con tact, allow the car parts
to cool down. Obser
vethefo llowing information: Note
s on cleaning and car eA voiding vehicle damage
Wheels/rims Usewate r and acid-free wheel cleaners. R
Do not use acidic wheel cleaners toremo vebrake dust.
This could damage wheel bolts and brake components.
R Toavoid cor rosion of the brake discs and brakepads, drive
th eve hicle for a few minutes af ter cleaning before parking
it. The brake discs and brakepads warm up and dry out.
Wi ndo ws
Clean windowsinside and outside with a damp clo thand with
a cleaning agent recommended for Mercedes-Benz. Do not use dry clo
ths or abrasive or sol vent-based cleaning
agents toclean the inside of windo ws.
