Operating safety
Important safetynotes
GWARNING
If you do not have the prescribed service/
maintenanc ework or any required repairs
carried out, this can result in malfunctions or system failures. There is arisk of an accident.
Always have the prescribed service/mainte-
nanc ework as well as any required repairs
carried out at aqualified specialist workshop.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is arisk
of fire.
When driving off road or on unpaved roads,
checkt he vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardiz ethe operatin gsafety of
the vehicle. There is an increased risk of an
accidenta nd injury.
Never tamper with the wiring as well as elec-
tronic component sortheir software. You
should have all work to electrical and elec-
tronic equipment carried out at aqualified
specialist workshop.
!There is arisk of damage to the vehicle if:
Rthe vehicle becomes stuck ,e.g. on ahigh
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g. a
curb or ahole in the road
Raheavy objec tstrikes the undercarriage or
parts of the chassis
In situation slike this, the body, the undercar-
riage, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust
system, they can catc hfire.
In such situations, have the vehicle checked
and repaired immediately at aqualified spe-
cialist workshop. If on continuin gyour jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult aqualified spe-
cialist workshop.

for example, the power steering and the brakeboosting effect. You wil lrequire considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment while driving, you wil lbedistracted from
traffic conditions. You coul dalsol ose control
of the vehicle. There is arisk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the lega lrequirements for the country
in which you are driving. Some jurisdictions pro-
hibi tthe drive rfrom using amobile phone while
driving avehicle.
If you make acall while driving, alway suse
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pul lover to asafe location and stop
before operating the telephone.
Bear in mind that at aspeedofo nly 30 mph
(approximately 50 km/h) ,the vehicl ecovers a
distance of 44 ft (approximately 14 m)per sec-

Drive sensibly –save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to the rec-
ommended tire pressure.
RRemove unnecessary loads.
RWarm up the engin eatlow engin espeeds.
RAvoid frequenta cceleration or braking.
RObserve the servicei ntervals in the Mainte-
nanc eBooklet or in the servicei nterval dis-
play. Have all the maintenanc ework carried in
accordance with Daimler AG regulations.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinkin gand driving and/or takin gdrugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of aserious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Thereforen ever leave
the engin erunning in enclosed spaces with-
out sufficientv entilation.
Certain engin esystems are designed to keep
the level of poisonous component sinexhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications .Always have
work on the engin ecarried out at aqualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
BenzC enter for this purpose. Work relevant to
safety or work on safety-related systems in par-
ticular must be carried out at aqualified spe-
cialist workshop.
The engin esettings must not be changed under
any circumstances. Furthermore, all specific
servicew ork must be carried out at regular
intervals and in accordance with the Mercedes-
Benzs ervicer equirements. Details can be found
in the Maintenanc eBooklet.
