DANG ER Risk of death caused by
ex haust gases
Combustion engines emit poisonous exhaust
ga ses such as carbon monoxide. Inhaling
th ese exhaust gases is hazardous tohealth
and leads topoisoning. #
Never lea vethe engine or, if present,
th e auxiliary heating running in an
enclosed space wi thout suf ficient venti‐
lation. &
WARNING Risk offire due toflammable
material in the engine compartment or
th eex haust sy stem
Flammable materials may ignite. #
Therefore, check regularly that there
are no flammable materials in the
engine compartment or on theex haust
sy stem. Re
quirements:
R theke y is located in theve hicle and thekey
battery is not dischar ged. #
Shift the transmission toposition jori. #
Depress the brake pedal and press button
1 once. #
Ifth eve hicle does not star t:switch off non-
essential consumers and press button 1
once. #
Ifth eve hicle still does not start and theKey
not detected display message also appears
in the multifunction display: start theve hicle
with theke y (/ page106).

WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may over‐
heat.
This increases the braking dis tance and the
brake sy stem may evenfa il. #
Never use the brake pedal as a foot re st. #
Do not depress the brake pedal and the
accelerator pedal at the same time
while driving. &
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

Therefore, obser
vethefo llowing no tes:
R due tosalt build-up on the brake disks and
brakepads, the braking dis tance can increase
considerably orresult in braking only on one
side
R maintain a much greater safe dis tance tothe
ve hicle in front
To remo vesalt build-up:
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
Note s on aquaplaning
Aq uaplaning can take place once a cer tain
amount of water has accumulated on thero ad
sur face.
Obser vethefo llowing no tes during heavy precip‐
itation or in conditions in which aquaplaning may
occur:
R reduce speed
R avoid tyre ruts R
avoid sudden steering mo vements
R brake carefully
% Also obser vethe no tes on regular lych ecking
wheels and tyres (/ page 321).
Note s on driving through water on the road
sur face
Wa ter which has entered into theve hicle can
damage the engine, electrics and transmission.
Wa ter can also enter the air intake of the engine
and cause engine damage.
Obser vethefo llowing if you must drive thro ugh
wate r:
R The water,when calm, may only reach the
lo we r edge of theve hicle body.
R Drive at walking pace at most, otherwise
wate r can enter theve hicle interior or engine
compartment.
R Vehicles tr avelling in front, or oncoming vehi‐
cles, can create waves which may exceed the
maximum permissible dep thofthewa ter.
The braking ef fect of the brakes is reduced af ter
fo rd ing. Brake carefully while paying attention toth
e traf fic conditions until braking po wer has
been fully restored. Fu
nction of rear axle steering The
rear axle steering is an electromechanical
auxiliary steering on there ar axle which adjusts
th esteering of there ar wheels according tothe
position of the front wheels, depending on the
speed. This results in greater manoeuvrability
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. when corner‐
ing
R more direct steering resulting in impr oved
handling of theve hicle

Information on
the AMG ceramic high-per‐
fo rm ance comp osite 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‐

R youstop behind a vehicle that is pulling
aw ay.
R youstop at a stop sign when there is no vehi‐

% In transmission position k,the engine is
not switched off automatically even when
