WARNING Risk of burn s duetorepeat‐
edly switching on the seat heater
Re peatedly switching on the seat heater can
cause the seat cushion and seat backrest
padding tobecome very hot.
The health of persons with limited temp era‐
ture sensitivity or a limited ability toreact to high
temp eratures may be af fected or they
may even su ffer burn-like injuries. #
Do not repeatedly switch on the seat
heater. To
protect against overheating, the seat heating
may be temp orarily deactivated af ter it is
switched on repeatedly.
* NO
TEDama getothe seats caused by
objects or documents when the seat
heater is switched on When
the seat heater is switched on, over‐
heating may occur due toobjects or docu‐
ments placed on the seats e.g. seat cushions
or child seats. This could cause damage to
th e seat sur face. #
Makesure that no objects or docu‐
ments are on the seats when the seat
heater is switched on. Re
quirements:
R The po wer supply is switched on. #

WARNING Risk of burn s causedbythe
heating output from AIRSCARF being too
high
When AIRSCARF is switched on, very hot air
can flow from the outlet opening in the head

WARNING Risk of accident due to
adjusting vehicle settings while theve hi‐
cle is in motion
Yo u could lose cont rol of theve hicle in the
fo llowing situations in particular:
R Ifyo u adjust the driver's seat, the head
re stra ints, thesteering wheel or the mir‐
ro r while theve hicle is in motion.
R Ifyo ufast enyour seat belt while theve hi‐
cle is in motion. #
Before starting the engine: adjust the
driver's seat, the head restra ints, the
st eering wheel and the mir ror and fas‐
te nyo ur seat belt. &

vehicle
occupants may come into contact with the
liquid and if it is hot, they could be scalded.
Yo u could be distracted from traf fic condi‐
tions and you may lose cont rol of theve hicle. #

WARNING ‑ Risk of fire and injury from
th e hot cigar ette lighter
Yo u can burn yourself if youto uch the hot
heating element or the soc ket of the ciga‐
re tte lighter.
In addition, flammable materials may ignite
if:
R you drop the hot cigar ette lighter
R ach ild holds the hot cigar ette lighter to
objects, forex ample #
Alw ays hold the cigar ette lighter bythe

WARNING Risk of burn s fromtheta il‐
pipe and tailpipe trims
The exhaust tailpipe and tailpipe trims can
become very hot. If you come into contact with
these parts of theve hicle, you could
burn yourself. #
Alw ays be particular lycareful around
th eta ilpipe and theta ilpipe trims and
supervise children especially closely in
th is area. #
Allow vehicle parts tocool down before
to uching them. The driving
characteristics of your vehicle are
dependent on the distribution of the load within
th eve hicle. You should bear thefo llowing in
mind when loading theve hicle:
R neverex ceed the permissible gross mass or
th e permissible axle loads forth eve hicle
(including occupants).
Information can be found on theve hicle iden‐
tification plate (/ page 280).
R position heavy loads as farfo rw ards as possi‐
ble and as low down in the boot as possible.
R the load must not pr otru de abo vethe upper

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

track ope ration, additional requirements must
be obser ved.
