Introduction

XTo close the tailgate automatically fromoutside the vehicle:if the SmartKey islocated in the immediate vicinity of the vehi-cle, press theTbutton on the SmartKey(Ypage 79).When the tailgate closes you can thenrelease the button.
KEYLESS-GO
General notes
Bear in mind that the engine can be started byany of the vehicle occupants if there is aSmartKey in the vehicle.
Locking and unlocking
You can start, lock or unlock the vehicle usingKEYLESS-GO. To do this, you only need carrythe SmartKey with you. You can combine thefunctions of KEYLESS-GO with those of a con-ventional SmartKey. Unlock the vehicle byusing KEYLESS-GO, for instance, and lock itusing the7button on the SmartKey.
The driver's door and the door at which thehandle is used, must both be closed. TheSmartKey must be outside the vehicle. Whenlocking or unlocking with KEYLESS-GO, thedistance between the SmartKey and the corre-sponding door handle must not be greaterthan three feet (one meter).
A check which periodically establishes a radioconnection between the vehicle and theSmartKey determines whether a valid Smart-Key is in the vehicle. This occurs, for example:
Rwhen starting the engine
Rwhile driving
Rwhen the external door handles are touched
Rduring convenience closing
XTo unlock the vehicle:touch the inner sur-face of the door handle.
XTo lock the vehicle:touch sensor sur-faceCorD.
Make sure that you do not touch the innersurface of the door handle.
XConvenience closing feature:touchrecessed sensor surfaceDfor an extendedperiod.
Further information on the convenienceclosing feature (Ypage 85).
XTo unlock the tailgate:pull tailgate han-dleC.
Deactivating and activating
If you do not intend to use the vehicle for alonger period of time, you can deactivate KEY-LESS-GO. The SmartKey will then use very lit-tle power, thereby conserving battery power.For the purposes of activation/deactivation,the vehicle must not be nearby.
XTo deactivate:press the7button onthe SmartKey twice in rapid succession.The indicator light on the SmartKey flashestwice briefly then one long flash, then KEY-LESS-GO is deactivated (Ypage 72).
XTo activate:press any button on the Smart-Key.
or
XInsert the SmartKey into the ignition lock.KEYLESS-GO and all of its associated fea-tures are available again.

ProblemPossible causes/consequences andPPSolutions
You can no longer lockor unlock the vehicleusing KEYLESS-GO.
The SmartKey battery is discharged or nearly discharged.
XCheck the SmartKey battery (Ypage 72) and replace it if neces-sary (Ypage 72).
If this does not work:
XUnlock (Ypage 76) or lock (Ypage 77) the vehicle using themechanical key.
There is interference from a powerful source of radio waves.
XUnlock (Ypage 76) or lock (Ypage 77) the vehicle using themechanical key.
KEYLESS-GO is malfunctioning.
XLock/unlock the vehicle using the remote control function of theSmartKey.
XHave the vehicle and SmartKey checked at a qualified specialistworkshop.
If the vehicle can also not be locked/unlocked using the remotecontrol function:
XUnlock (Ypage 76) or lock (Ypage 77) the vehicle using themechanical key.
XHave the vehicle and SmartKey checked at a qualified specialistworkshop.
The engine cannot bestarted using the Smart-Key.
The on-board voltage is too low
XSwitch off non-essential consumers, e.g. seat heating or interiorlighting, and try to start the engine again.
If this does not work:

Opening and closing

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:avoid full-loadoperation and engine speeds greater than5000 rpm when the engine is cold. Thishelps to protect the engine and avoidsuncomfortable driving.

ITo start the engine
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.
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 theSmartKey determines whether a valid Smart-Key is in the vehicle. This occurs, for example,when starting the engine.
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 differentSmartKey positions in the ignition lock. This isonly the case if you are not depressing thebrake 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 inthe ignition lock
Rthe SmartKey must be in the vehicle
Rthe vehicle must not be locked with theSmartKey or KEYLESS-GO (Ypage 70)
Do not keep the KEYLESS-GO key:
Rwith electronic devices, e.g. a mobile phoneor another SmartKey.
Rwith metallic objects, e.g. coins or metalfoil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of KEYLESS-GO.
If you lock the vehicle with the SmartKeyremote control or with KEYLESS-GO, after ashort 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 vehicleis unlocked again.
If you lock the vehicle centrally using the but-ton on the front door (Ypage 75), you cancontinue to start the engine with the Start/Stop button.
