Refueling
Important safety notes
GWARNING
Fuel is highly flammable. Risk of fire and
explosion by improper handling of fuel.
You must avoid fire, open flames, smoking
and creating sparks. Switch off the ignition
before refueling and, if present, switch off
the auxiliary heating.
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.

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.
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.
RWarm up the engine at low engine speeds.
RAvoid frequent acceleration or braking.
RObserve the service intervals in the Mainte-nance Booklet or in the service interval dis-play. Have all the maintenance work carriedin accordance with Daimler AG regulations.
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.

economical driving. A higher level indicates amore economical driving style. If the threeouter areas are completely filled at the sametime, the driver has adopted the most eco-nomical driving style for the selected settingsand prevailing conditions. The ECO displayborder lights up.
The ECO display does not indicate the actualfuel consumption. The additionally achievedrange displayed underBonus fr. startBonus fr. startdoesnot indicate a fixed consumption reduction.
In addition to driving style, the actual con-sumption is affected by other factors, such as:
Rload
Rtire pressure
Rcold start
Rchoice of route
Ractive electrical consumers
These factors are not included in the ECO dis-play.
An economical driving style specially requiresdriving at moderate engine speeds.
Achieving a higher value in the categories"Acceleration" and "Constant":
Robserve the gearshift recommendations.
Rdrive the vehicle in drive programCorE.
In urban traffic and stop-start traffic, drive pro-gramCis recommended.
On long journeys at a constant speed, e.g. onthe highway, only the outer area for "constant"will change.
The ECO display summarizes the driving stylefrom the start of the journey to its completion.Therefore, there are more marked changes inthe outer areas at the start of a journey. Onlonger journeys, there are fewer changes. Formore marked changes, perform a manual rest(Ypage 171).
Further information on the ECO display(Ypage 170).
Braking
Important safety notes
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding and accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients
!On long, steep gradients, you must reducethe load on the brakes. To use engine brak-ing, shift to a lower gear in good time. Thishelps you to avoid overheating the brakesand wearing them out excessively.
When making use of the engine brakingeffect, it is possible that a drive wheel maynot turn for some time, e.g. in the case ofsuddenly changing or slippery road surfaceconditions. This could cause damage to thedrive train. This type of damage is not cov-ered by the Mercedes-Benz warranty.
Change into a lower gear in good time on longand steep downhill gradients. This is especiallyimportant if the vehicle is laden.
This also applies if you have activated cruisecontrol or Active Distance Assist DISTRONIC.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal
while driving, the braking system can over-
heat. This increases the stopping distance
and can even cause the braking system to
fail. There is a risk of an accident.
Never use the brake pedal as a footrest.
Never depress the brake pedal and the
accelerator pedal at the same time.
!Depressing the brake pedal constantlyresults in excessive and premature wear tothe brake pads.
If the brakes have been subjected to a heavyload, do not stop the vehicle immediately, butdrive on for a short while. This allows the air-flow to cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy rainwithout braking, there may be a delayed reac-tion from the brakes when braking for the first

Z

time. This may also occur after the vehicle hasbeen washed or driven through deep water.
You then have to depress the brake pedalmore firmly. Maintain a greater distance fromthe vehicle in front.
After driving on a wet road or having the vehi-cle washed, brake firmly while paying attentionto the traffic conditions. This will warm up thebrake discs, thereby drying them more quicklyand protecting them against corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-due may form on the brake discs and brakepads. This can result in a significantly longerbraking distance.
RIn order to prevent any salt build-up, applythe brakes occasionally while paying atten-tion to the traffic conditions.
RCarefully depress the brake pedal and thebeginning and end of a journey.
RMaintain a greater distance to the vehicleahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up inthe instrument cluster and
Ryou hear a warning tone while the engineis running
Observe additional warning messages in themultifunction display.
The brake fluid level may be too low due tobrake pad wear or leaking brake lines.
Have the brake system checked immedi-ately. Consult a qualified specialist work-shop to arrange this.
!As the ESP®system operates automati-cally, the engine and the ignition must beswitched off (the SmartKey must be in posi-tion

driving and braking accordingly during thisbreak-in period.
Excessive heavy braking results in correspond-ingly high brake wear. Observe the brake sys-tem warning lamp in the instrument clusterand note any brake status messages in themultifunction display. Especially for high per-formance driving, it is important to maintainand have the brake system checked regularly.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth onthe road surface, there is a danger of hydro-planing occurring.
For this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:
Rlower your speed
Ravoid ruts
Ravoid sudden steering movements
Rbrake carefully
Driving on flooded roads
!Do not drive through flooded areas. Checkthe depth of any water before drivingthrough it. Drive slowly through standingwater. Otherwise, water could enter thevehicle interior or engine compartment. Itcan then damage the engine's or automatictransmission's electronic components. Itcan also be sucked in by the engine's airintake connection and cause engine dam-age.
Winter driving
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding and accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter
the vehicle. This is the case, e.g. if the vehi-
cle becomes trapped in snow. There is a risk
of fatal injury.
If you leave the engine or the auxiliary heat-
ing running, make sure the exhaust pipe and
area around the vehicle are clear of snow.
To ensure an adequate supply of fresh air,
open a window on the side of the vehicle
that is not facing into the wind.
Have your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.
Drive particularly carefully on slippery roadsurfaces. Avoid sudden acceleration, steeringand braking maneuvers. Do not use cruisecontrol.
If the vehicle threatens to skid or cannot bestopped when moving at low speed:
XShift the transmission to position\\.
The outside temperature indicator is notdesigned to serve as an ice-warning deviceand is therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.
Indicated temperatures just above the freezingpoint do not guarantee that the road surface isfree of ice. The road may still be icy, especiallyin wooded areas or on bridges. The vehiclecould skid if you fail to adapt your drivingstyle. Always adapt your driving style and driveat a speed to suit the prevailing weather condi-tions.
You should pay special attention to road con-ditions when temperatures are around freezingpoint.
