ESP®(Electronic Stability Program)
General notes
ESP®monitors driving stabilitya nd detectsa
tendenc yofthevehicle to understeer or over-
steer (skidding) in good time. If ESP
®detects
that th evehicle is deviatin gfromt hedirection
desired by th edriver, oneorm orew heels are
braked to stabilizet hevehicle .The engine out-
put is also modified to keep th evehicle on the
desired course within physical limits. ESP
®can

Drive sensibly –save fuel
In order to save fuel, observe the following tips:
XThe tires should alwaysbei nflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof carriers when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenanc ework carried out as
indicated by the servicei ntervals in the Main-
tenance Booklet or by the servicei nterval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in moun-
tainous terrain.
Overrun cutoff
If you are in overrun mode and take your foot off
the accelerator pedal, the fuel supply is cut off
when the engine speed is out of the idle speed
control range.
Drinking and driving
GWARNING
Drinking and 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 engine running in enclosed spaces with-
out sufficien tventilation.
Certain engine systems are designed to keep
the level of poisonous substances in exhaust
fumes within legal limits.
These systems only work optimally if they are
maintained exactly in accordance with the man-
ufacturer's specifications. An ywork on the
engine should therefore be carried out by quali-
fied and authorized Mercedes-Benz technicians.
The engine settings must not be changed under
any circumstances. In addition, all specific
maintenanc ework must be carried out at regu-
lar intervals and in accordance with the service
requirement softhe dealer listed here on the
inside title page. Details can be found in the
Maintenance Booklet.
Speed limiter
GWARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed could
lead to tire damage or the tire bursting. There is ar isk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe the
tire load ratin gand speed ratin grequired for
your vehicle.
As the driver, you must be aware of the maxi-
mum design speed of the vehicle and the maxi- mum permissible speed based on the tires (tire
and tire pressure). In particular, also observe the tire approval regulations for each country.
You must, under no circumstances, exceed the
speed limit for the tires specified by the speed
index. The speed ratin gisstated in the tire
tables (
Ypage 291).
You can permanently limit the maximum speed
of your vehicle, e.g. for driving on winter tires.

GWARNING
When objects are unsecured or inadequately
secured, they can slip, turn over or be thrown
about, strikin gvehicle occupants .This also
applies to:
Rluggage or loads
Rseats which have been removed and are
being transported in the vehicle in an
exceptional case.
There is arisk of injury, particularly in the
eventofab rakingmaneuver or abrupt change
in direction.
Always stow objects in such away that they
cannot be tossed about. Beforet raveling,
secure objects, luggage or loads to prevent
them slipping or tippin gover. If you removea
seat, stor eitpreferably outside the vehicle.
GWARNING
As aresult of improperly placed or unevenly
distributed loads, the center of gravityoft he
load being transported may be too high or too
far back. This can significantly impair handling
as well as steering and brakin gcharacteris-
tics. There is arisk of an accident.
Always make sure that the center of gravityo f
the load is:
Rbetween the axles
and
Ras low as possible, near the rear axle.
GWARNING
When the permissible wheel loads, axle loads
and/o rthe maximum permissible gross vehi-
cle weight are exceeded, drivings afetyis
compromised. The handlin gaswell as steer-
ing and brakin gcharacteristic smay be signif-
icantly impaired. Overloaded tires may over-
heat, causing them to burst. There is arisk of
an accident.
When transporting aload, always observet he
permissible wheel loads, axle loads and the
maximum permissible gross vehicle weight
for the vehicle (includin goccupants).
!If you are using aroof carrier,o bservethe
maximum roof load and maximum roof carrier
load.
RDo not stac kluggage or loads higher than the
backrests.
RObjects to be transported should preferably
be stowed in the cargo compartment.
RWhen transporting luggage, always use the
cargo tie-down rings for securingl oads and a
cargo net ,ifinstalled.
RUse cargo tie-down rings and fasteners which
are suitable for the weight and size of the
load.
When using suitable load securin gaids and tie
downs, always follow the manufacturer's oper-
ating instructions, in particular the notes on dis-
card criteria contained therein.
Load securin gaids or tie downs must not be
used if:

Operation
Information for ajourney
If the vehicle is heavily laden, checkt he tire
pressures,a nd correct them ,ifnecessary
(
Ypage 270).
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pull-
ing to one side. This may indicat ethat the
wheels or tires are damaged. If you suspect that
at ire is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
checkt he wheels and tires for damage. Hidden
tire damage could also be causing the unusual
handling characteristics. If you find no signs of
damage, have the tires and wheels checked at a
qualified specialist workshop.
When parkin gyour vehicle, make sure that the
tires do not get deformed by the curb or other
obstacles. If it is necessary to drive over curbs,
speed humps or similar elevations, try to do so
slowly and not at asharp angle. Otherwise, the
tires ,particularly the sidewalls, can get dam-
aged.
