GWARNING
Fuels are toxic and harmful to health. There
is a risk of injury.
You must avoid fuels coming into contact
with skin, eyes and clothes or being swal-
lowed.
Do not inhale the fuel vapors. Keep children
away from fuels.
Keep doors and windows closed during the
refueling process.
If you or others come into contact with fuel,
observe the following points:
RImmediately rinse the fuel off your skin
with soap and water.
RIf you get fuel into your eyes, immediately
rinse your eyes throughly with clean
water. Seek medical attention immedi-
ately.
RSeek medical attention immediately if fuel
has been swallowed. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic charging can lead to the crea-
tion of sparks and ignite fuel vapor. There is
a risk of fire and explosion.
Touch the metallic body of the vehicle
before you open the fuel filler cap or handle
the pump nozzle. Any possible electrostatic
charge present will in this way be depleted.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
!Do not use diesel to refuel vehicles with agasoline engine. Do not switch on the igni-tion if you accidentally refuel with the wrongfuel. Otherwise, the fuel will enter the fuelsystem. Even small amounts of the wrongfuel could result in damage to the fuel sys-tem and the engine. Notify a qualified spe-cialist workshop and have the fuel tank andfuel lines drained completely.
!Overfilling the fuel tank could damage thefuel system.
!Take care not to spill any fuel on paintedsurfaces. You could otherwise damage thepaintwork.
!Use a filter when adding fuel from a fuelcan. The fuel lines and/or the fuel injectionsystem could otherwise be blocked by parti-cles from the fuel can.
Do not get into the vehicle again during therefueling process. Otherwise, electrostaticcharge could build up again.
If you overfill the fuel tank, fuel could sprayout when the fuel pump nozzle is removed.

Driving tips
General notes
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could
affect, for example, the power steering and
the brake boosting effect. You will require
considerably more effort to steer and brake.
There is a risk of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. You could also
lose control of the vehicle. There is a risk of
an accident.
Only operate this equipment when the vehi-
cle is stationary.
Observe the legal requirements for the countryin which you are driving. Some jurisdictionsprohibit the driver from using a mobile phonewhile driving a vehicle.
If you make a call while driving, always usehands-free mode. Only operate the telephonewhen the traffic situation permits. If you areunsure, pull over to a safe location and stopbefore operating the telephone.
148Driving tips
Driving and parking

Bear in mind that at a speed of only 30 mph(approximately 50 km/h), the vehicle covers adistance of 44 ft (approximately 14 m) persecond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to therecommended tire pressure.
RRemove unnecessary loads.
RRemove roof racks when they are not nee-ded.
RWarm up the engine at low engine speeds.
RAvoid frequent acceleration or braking.
RHave all maintenance work carried out asindicated by the service intervals in theMaintenance Booklet or by the service inter-val display.
Fuel consumption also increases when drivingin cold weather, in stop-start traffic and in hillyterrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident 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
taking drugs.
Emission control
GDANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases is hazardous to
health and can result in poisoning. There is a
risk of fatal injury. Therefore, never leave the
engine running an enclosed space without
adequate ventilation.
Certain engine systems are designed to keepthe level of poisonous components in exhaustfumes within legal limits.
These systems only work at peak efficiency ifthey are serviced exactly in accordance withthe manufacturer's specifications. Always havework on the engine carried out at a qualifiedspecialist workshop. Mercedes-Benz recom-mends that you use an authorized Mercedes-Benz Center for this purpose. In particular,work relevant to safety or on safety-relatedsystems must be carried out at a qualified spe-cialist workshop.
The engine settings must not be changedunder any circumstances. Furthermore, allspecific service work must be carried out atregular intervals and in accordance with theMercedes-Benz service requirements. Detailscan be found in the Maintenance Booklet.
ECO display
The ECO display shows you how economicalyour driving style is. The ECO display assistsyou in achieving the most economical drivingstyle for the selected settings and prevailingconditions. Your driving style can significantlyinfluence the vehicle's consumption.
CAcceleration
DCoasting

The ECO display consists of three sections,with an inner and outer area. The sections cor-respond to the following three categories:
CAcceleration(evaluation of theacceleration processes):
Rthe outer area fills up and theinner area lights up green: moder-ate acceleration, especially athigher speeds
Rthe outer area empties and theinner area is gray: sporty acceler-ation
DCoasting(evaluation of all deceler-ation processes):
Rthe outer area fills up and theinner area lights up green: antici-patory driving, keeping your dis-tance and early release of theaccelerator. The vehicle cancoast without use of the brakes.
Rthe outer area empties and theinner area is gray: frequent heavybraking
