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 driving off.
!Do not warm up the engine while stationary.
Pull away immediately. Avoid high engine
speeds and full throttle until the engine has
reached 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 drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
!Mercedes-AMG vehicles: at low engine oil
temperatures below 68 ‡ (+20 †), the max-
imum engine speed is restricted in order to
protect the engine. To protect the engine and
maintain smooth engine operation, avoid driv-
ing at full throttle when the engine is cold.

3To start the engine
iThe SmartKey can be turned in the ignition
lock even if it is not the correct SmartKey for
the vehicle. The ignition is not switched on.
The engine cannot be started.
KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped with a
SmartKey featuring an integrated KEYLESS-GO
start function and a detachable Start/Stop but-
ton.
The Start/Stop button must be inserted in the
ignition lock and the SmartKey must be in the
vehicle.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different key
positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in

If a malfunction in the electric parking brake
occurs, the transmission may also be shifted
into positionjautomatically.
RACE START
Important safety notes
iRACE START must not be used on normal
roads. RACE START must only be activated
and used on dedicated road circuits, outside
of public road use.
iRACE START is only available for Mercedes-
AMG vehicles except Mercedes-AMG C 43
4MATIC.
iRACE START is only available for Mercedes-
AMG vehicles except Mercedes-AMG C 43
4MATIC.
RACE START enables optimal acceleration from
a standing start. For this, a suitably high-grip
road surface is required and the vehicle and tires
must be in good working order.
GWARNING
If you use RACE START, individual tires may
start to spin and the vehicle could skid.
Depending on the selected ESP
®mode, there
is an increased risk of skidding and having an accident. Make sure that no persons, animals
or obstacles are within range of the vehicle.
iObserve the safety notes on driving safety
systems (Ypage 60).
Be sure to read the safety notes and informa-
tion on ESP
®(Ypage 65).
Conditions for activation
You can activate RACE START if:
Rthe doors are closed.
Rthe engine is running and it has reached an
operating temperature of approximately
160 ‡ (71 †). This is the case when the oil
temperature gauge in the multifunction dis-
play is shown in white.
Rthe engine is running and the engine and
transmission are at operating temperature.
This is the case when the oil temperature
gauge in the multifunction display is shown in
white (
Ypage 197).
RESP®is functioning correctly. (Ypage 65)
Rthe drive program S,S+ orRace is selected
(Ypage 129)
Rthe steering wheel is in the straight-ahead
position.
Rthe vehicle is stationary and the brake pedal is
depressed (left foot).
Rthe transmission is in position D.
Activating RACE START
iWhen manual mode (Ypage 136) is active,
the transmission automatically shifts up to
RACE START in the drive program. This func-
tion supports maximum acceleration with
RACE START. After going through an acceler-
ating process once from a stationary position, this function is automatically deactivated.
XDepress the brake pedal with your left foot
and keep it depressed.
XPull and hold both steering wheel paddle shift-
ers.
XThe RACE START Confirm: Paddle UPCancel: Paddle DOWNmessage appears in
the multifunction display.
XRelease both steering wheel paddle shifters.
iIf the activation conditions are no longer ful-
filled, RACE START is canceled. The RACE

multifunction display.
XTo cancel: pull the left steering wheel paddle
shifter (Ypage 136).

Dependin g on the engine, the oil dipstick may be
in adiff erent location.
When checking the oil leve l:
Rpark the vehicleon a level surface
Rthe engine should be switched off for approx-
imately five minutes ifthe engine isat normal
operating temperature
Rif the engine isnot at normal operating tem-
perature, e.g. ifthe engine was only started
brie fly,wait about 30 minute sbefore carrying
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.
Example
XPull out oil dipstick :.
XWipe off oil dipstick :.
XSlowly slide oil dipstick :into the guide tube
to the stop, and take it out again.
If the level is between MIN mark =and MAX
mark ;, the oil level is correct.
XIf the oil level has dropped to MIN mark =or
below, add 1.1 US qt (1.0 liter) of engine oil.
