Please also obser vethefo llowing running-in
no tes:
R in cer tain driving and driving saf ety sy stems,
th e sensors adjust automatically while a cer‐
ta in dis tance is being driven af terth eve hicle
has been delivered or af terre pairs. Full sys‐ te
m ef fectiveness is not reached until the
end of this teach-in process.
R brakepads, brake discs and tyres that are
either new or ha vebeen replaced only ach‐
ie ve optimum braking ef fect and grip af ter
se veral hundred kilom etre s of driving. Com‐
pensate forth ere duced braking ef fect by
applying greaterfo rc eto the brake pedal. Note
s on engine output and engine torq ue %
The actual (maximum) values that can be
achie vedfo r engine output and engine tor‐
qu e may deviate from the certified values
within the count ry-specific guidelines for
permissible tolerances (basis: UN-ECE No.

Fa ctors that can influence this are, forex am‐
ple:
R sea le vel
R fuel grade
R outside temp erature
R operating temp erature of the engine Unti

perature, thefo llowing engine operating temp er‐
ature warning lamp is lit: Engine output and engine

This jeopardises the operating and road
saf ety of theve hicle. Driving and parking

#
Open a window on the side of theve hi‐
cle facing away from the wind toensure
an adequate supply of fresh air. &
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
h ork when theve hicle is at a
st andstill, alw ays depress the brake
pedal firm lyand do not accelerate at
th e same time. *

Have the cause rectified immediately at
a qu alified specialist workshop. Note
s on driving on salt-treated roads
The braking ef fect is limited on salt-trea ted
ro ads. Driving and parking

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 environmen tal conditions, e.g. temp erature
and air humidity

The engine is switched off auto matically inthe
fo llowing situations if all vehicle conditions for
an automatic engine stop are me t:
R you brake theve hicle toast andstill in trans‐
mission position hori. If
yo u swit chon the HOLD function in transmis‐
sion position hori, the engine will automati‐
cally stop in thefo llowing situations:
R youstop behind a vehicle that is pulling
aw ay.
R youstop at a stop sign when there is no vehi‐
cle in front of you.
R you turn thesteering wheel hard at a low

% In transmission position k,the engine is
not switched off automatically even when
th e HOLD function is switched on.
The engine is restar ted automatically if:
R youre lease the brake pedal in transmission
position hwhen the HOLD function is not
active and theve hicle does not start to
mo ve.
R you shift from transmission position j.
R youre lease the brake pedal and theve hicle

Ra
cetrack operation Information on
racetrack operation %
Racetrack opera tion is understood as the
operation of theve hicle in extreme situa‐
tions when it is used on race trac ksor
closed-off trac ks.
Yo ur vehicle may be used on bo thpublic roads
and race trac ks. The vehicle operating loads dif‐
fe r depending on use, which require dif fering
maintenance inter vals.
When theve hicle is operated on a racetrac k,the
component pa rts are subject tohigher loads
th an on thero ad.
To account forth ese loads, thefo llowing meas‐
ures in particular are take n as pa rtof the main‐
te nance inter vals:
R Checking and replacing individual compo‐
nents
R Overhauling comple teassemblies af ter spe‐
cific periods of use Ad
ditional checks must alw ays be car ried out on
th eve hicle before and af ter each use on a race‐
trac k.
* NO
TEDama getocomponent pa rts
th ro ugh a rise in temp erature af ter oper‐
ation on a racetrack Switching
theve hicle off directly af ter opera‐
tion on a racetrack can lead toa continued
te mp erature increase of the component
parts as a result of heating while theve hicle
is stationar y.
The component parts may thereby be perma‐
nently damaged in exceptional cases. #
Do not switch off theve hicle immedi‐
atel y.Car ryout cool down laps at low
speed with minimal brake application.
Assemblies under stra in, such as the
engine and the braking sy stem, cool
down fasterthis wa y. #
Alw ays allow a Trac k-Check tobe car‐
ri ed out at a Mercedes-Benz Service
Centre before and af ter use on the
ra cetrac k. Mo
torsport equipment, e.g. six-point seat belts,
are only intended for use where road traf fic re g‐
ulations do not appl y.This also applies tomodifi‐
cations toboth th e suspension and aerodynamic
component parts.
Yo u can obtain fur ther information on servicing
yo ur vehicle from a Mercedes-Benz Service
Centre. Note
s onthech aracteristics of individual
ve hicle assemblies Due
tospecific vehicle operating loads in race‐
track ope ration, additional requirements must
be obser ved.
