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 the parking brake has not been fully
released when driving, the parking brake
can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident.
Release the parking brake fully before driv-
ing off.
!Do not warm up the engine while station-ary. Pull away immediately. Avoid highengine speeds and full throttle until theengine has reached its operating tempera-ture.
In vehicles with automatic transmission,engage positions P and R only when thevehicle is stationary.
Where possible, avoid spinning the drivewheels when pulling away on slippery roads.You could otherwise damage the drive train.
!Mercedes-AMG vehicles:at low engineoil temperatures below 68 ‡ (+20 †), themaximum engine speed is restricted inorder to protect the engine. To protect theengine and maintain smooth engine opera-tion, avoid driving at full throttle when theengine is cold.

iThe SmartKey can be turned in the ignitionlock even if it is not the correct SmartKeyfor the vehicle. The ignition is not switchedon. The engine cannot be started.
KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped witha SmartKey featuring an integrated KEYLESS-GO start function and a detachable Start/Stopbutton.
The Start/Stop button must be inserted in theignition lock and the SmartKey must be in thevehicle.
When you insert the Start/Stop button intothe ignition lock, the system needs approx-imately two seconds recognition time. You canthen use the Start/Stop button.
Pressing the Start/Stop button several timesin succession corresponds to the different keypositions in the ignition lock. This is only thecase if you are not depressing the brake pedal.
If you depress the brake pedal and press theStart/Stop button, the engine starts immedi-ately.
A check which periodically establishes a radioconnection between the vehicle and theSmartKey determines whether a valid Smart-

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 and parking

XReach into the gap, pull hood catch han-dleDup and lift hoodC.
If you lift the hood by approximately 15 in(40 cm), the hood is opened and held openautomatically by the gas-filled strut.
Closing the hood
XLower the hood and let it fall from a heightof approximately 8 in (20 cm).
XCheck that the hood has engaged properly.If the hood can be raised slightly, it is notproperly engaged. Open it again and close itwith a little more force.
Engine oil
Notes on the oil level
Depending on your driving style, the vehicleconsumes up to 0.9 US qt(0.8 liters) of oil per600 miles (1,000 km). The oil consumptionmay be higher than this when the vehicle isnew or if you frequently drive at high enginespeeds.
Depending on the engine, the oil dipstick maybe in a different location.
When checking the oil level:
Rpark the vehicle on a level surface
Rthe engine should be switched off forapproximately five minutes if the engine isat normal operating temperature
Rif the engine is not at normal operating tem-perature, e.g. if the engine was only startedbriefly, wait about 30 minutes before carry-ing out the measurement
Checking the oil level using the oil dip-
stick
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very
hot. Working in the engine compartment
poses a risk of injury.
Only touch the following components descri-
bed.
If work is being carried out on public roads,pay attention to the road and traffic conditionsand secure the area as appropriate.
Example
XPull out oil dipstickC.
XWipe off oil dipstickC.
XSlowly slide oil dipstickCinto the guidetube as far as it will go, and take it outagain.If the level is between MIN mark

GWARNING
If engine oil comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Make sure that engine oil is not spilled next
to the filler neck. Let the engine cool down
and thoroughly clean the engine oil off the
components before starting the engine.
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
!Use only engine oils and oil filters that areapproved for vehicles with a service system.A list of the engine oils and oil filters thathave been tested and approved in accord-ance with Mercedes-Benz Specifications forService Products is available at any author-ized Mercedes-Benz Center.
The following cause engine failure or dam-age to the exhaust system:
RUse of engine oils and oil filters that havenot been expressly approved for the ser-vice system
RReplacement of engine oil and oil filterafter the replacement interval specifiedby the service system has expired
RUse of engine oil additives
!Do not add too much oil. If the oil level isabove the "max" mark on the dipstick, toomuch oil has been added. This can lead todamage to the engine or the catalytic con-verter. Have excess oil siphoned off.
Example: engine oil cap
XTurn capCcounter-clockwise and removeit.
XAdd engine oil.If the oil level is at or below the MIN markon the oil dipstick, add 1.1 US qt (1.0 liter)of engine oil.
XReplace capCon the filler neck and turnclockwise.Ensure that the cap locks into placesecurely.
XCheck the oil level again with the oil dipstick(Ypage 266).

Checking and adding other service
products
Checking coolant level
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very
hot. Working in the engine compartment
poses a risk of injury.
Where possible, let the engine cool down
and touch only the components described in
the following.
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off.
There is a risk of injury.
