!Do not warm up the engine while stationary.Pull away immediately. Avoid high enginespeeds and full throttle until the engine hasreached its operating temperature.
In vehicles with automatic transmission,engage positions P and R only when the vehi-cle is stationary.
Where possible, avoid spinning the drivewheels when pulling away on slippery roads.You could otherwise damage the drive train.
!Mercedes-AMG vehicles:avoid full-loadoperation and engine speeds greater than5000 rpm when the engine is cold. This helpsto protect the engine and avoids uncomfort-able driving.

Start/Stop button
General notes
Vehicles with KEYLESS-GO are equipped withSmartKeys featuring the integrated KEYLESS-GO function and a detachable Start/Stop but-ton.
A check which periodically establishes a radioconnection between the vehicle and the Smart-Key determines whether a valid SmartKey is inthe vehicle. This occurs, for example, whenstarting the engine.
When you insert the Start/Stop button into theignition lock, the system needs approximatelytwo seconds recognition time. You can then usethe Start/Stop button.
Pressing the Start/Stop button several times insuccession corresponds to the different Smart-Key positions 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.
To start the vehicle without actively using theSmartKey:
Rthe Start/Stop button must be inserted in theignition lock
Rthe SmartKey must be in the vehicle
Rthe vehicle must not be locked with theSmartKey or KEYLESS-GO (Ypage 71)
Do not keep the KEYLESS-GO key:
Rwith electronic devices, e.g. a mobile phoneor another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of KEYLESS-GO.
If you lock the vehicle with the SmartKey remotecontrol or with KEYLESS-GO, after a short time:
Ryou will not be able to switch on the ignitionwith the Start/Stop button.
Ryou will no longer be able to start the enginewith the Start/Stop button until the vehicle isunlocked again.
If you lock the vehicle centrally using the buttonon the front door (Ypage 76), you can continueto start the engine with the Start/Stop button.
The engine can be switched off while the vehicleis in motion by pressing and holding the Start/Stop button for three seconds. This functionoperates independently of the ECO start/stopautomatic engine switch-off function.

Driving and pa rking

Engine compartment
Hood
Important safety notes
GWARNING
If the hood is unlatched, it may open up when
the vehicle is in motion and block your view.
There is a risk of an accident.
Never unlatch the hood while driving. Before
every trip, ensure that the hood is locked.
GWARNING

a risk of injury to persons within range of
movement of the hood.
Open and close the hood only when no one is
within its range of movement.
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

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.
If you need to do any work inside the engine
compartment:
Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from moving parts
GWARNING
The ignition system and the fuel injection sys-
tem work under high voltage. If you touch
components which are under voltage, you
could get an electric shock. There is a risk of
injury.
Never touch components of the ignition sys-
tem or fuel injection system when the ignition
is switched on.
To ensure the flow of fresh air through the airvents into the vehicle interior, please observethe following notes (Ypage 121):

Where possible, let the engine cool down and
touch only the components described in the
following.
GWARNING
When the hood is open and the windshield
wipers are set in motion, you can be injured by
the wiper linkage. There is a risk of injury.

Cleaning the vehicle parts
Cleaning the wheels
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Do not use acidic wheel cleaning productsto remove brake dust. This could damagewheel bolts and brake components.
!Do not park your vehicle for a long period oftime directly after cleaning, particularly aftercleaning the wheel rim with wheel cleaner.Wheel cleaner can lead to the increased cor-rosion of the brake discs and pads. Therefore,drive for a few minutes after cleaning. Byheating up the brakes, the brake discs andpads dry. The vehicle can then be parked for along period of time.
Cleaning the windows
GWARNING
You could become trapped by the windshield
wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
!Only fold the windshield wipers away fromthe windshield when vertical. Otherwise, youwill damage the hood.
!Do not use dry cloths, abrasive products,solvents or cleaning agents containing sol-vents to clean the inside of the windows. Donot touch the insides of the windows withhard objects, e.g. an ice scraper or ring. Thereis otherwise a risk of damaging the windows.
!Clean the water drainage channels of thewindshield and the rear window at regularintervals. Deposits such as leaves, petals andpollen may under certain circumstances pre-vent water from draining away. This can leadto corrosion damage and damage to elec-tronic components.
XClean the inside and outside of the windowswith a damp cloth and a cleaning product thatis recommended and approved by Mercedes-Benz.
