SmartKey
Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Roperate the vehicle's equipment
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake
Rshift the automatic transmission out of park
position]
Rstart the engine
There is a risk of an accident and injury.
Never leave children or animals unattended in
the vehicle.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. This
also applies for the Digital Vehicle Key if the
"Digital Vehicle Key" function is activated via
Mercedes me connect.
GWARNING
If you attach heavy or large objects to the
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a
risk of an accident.
Do not attach any heavy or large objects to the
SmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
!Keep the SmartKey away from strong mag-netic fields. Otherwise, the remote controlfunction could be affected.
Strong magnetic fields can occur in the vicin-ity of powerful electrical installations.
Do not keep the SmartKey:
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
Vehicles with KEYLESS-GO start function:donot keep the SmartKey in the trunk. Otherwise,
the SmartKey may not be detected, e.g. whenstarting the engine using the Start/Stop button.

DTTo open the trunk lid

!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.

iThe SmartKey can be turned in the ignitionlock even if it is not the correct SmartKey forthe vehicle. The ignition is not switched on.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 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.

Holding the vehicle stationary on uphill
gradients
GWARNING
If the clutch overheats, the electronic man-
agement system is automatically deactivated.
This interrupts the power transmission. The
vehicle may, for example, roll backwards on
gradients. There is a risk of an accident.
Never hold the vehicle stationary on uphill
gradients by depressing the accelerator.
The clutch may overheat if you hold the vehiclestationary on uphill gradients by depressing theaccelerator pedal. If the clutch overheats, awarning tone sounds.

Kickdown
Use kickdown for maximum acceleration.
XDepress the accelerator pedal beyond thepressure point.The automatic transmission shifts to a lowergear depending on the engine speed.
XEase off the accelerator pedal once thedesired speed is reached.The automatic transmission shifts back up.
Mercedes-AMG vehicles:it is only possible touse kickdown in the automatic drive programand the temporary manual drive programM.When manual drive programMis permanentlyactivated, kickdown is not possible.
For further information on kickdown in manualdrive programM(Ypage 139).
Rocking the vehicle free
Shifting back and forth between transmissionpositions[and^can help to free up thevehicle if it gets stuck in mud or snow. The vehi-cle's engine management system limits thespeed to a maximum of 5 mph (9 km/h) whenshifting back and forth. To shift repeatedlybetween transmission positions[and^,move the DIRECT SELECT lever up and downpast the point of resistance.

Kickdown
XFor maximum acceleration, depress theaccelerator pedal beyond the pressure point.The automatic transmission shifts to a lowergear depending on the engine speed.
XShift back up once the desired speed isreached.
During kickdown, you cannot shift gears usingthe steering wheel paddle shifters.
If you apply full throttle, the automatic trans-mission shifts up to the next gear when themaximum engine speed is reached. This pre-vents the engine from overrevving.
Mercedes-AMG vehicles:it is only possible touse kickdown in temporary manual drive pro-gramM. When manual drive programMis per-manently activated, kickdown is not possible.

Tire-mounting tools should not be used nearthe valve. This could damage the electroniccomponents.
Only have tires changed at a qualified spe-cialist workshop.
Observe the instructions and safety notes in the"Changing a wheel" section (Ypage 310).
The wear patterns on the front and rear tiresdiffer, depending on the operating conditions.Rotate the wheels before a clear wear patternhas formed on the tires. Front tires typicallywear more on the shoulders and the rear tires inthe center.
On vehicles that have the same size front andrear wheels, you can rotate the wheels accord-ing to the intervals in the tire manufacturer'swarranty book in your vehicle documents. If nowarranty book is available, the tires should berotated every 3,000 to 6,000 miles (5,000 to10,000 km). Depending on tire wear, this maybe required earlier. Do not change the directionof wheel rotation.
Clean the contact surfaces of the wheel and thebrake disc thoroughly every time a wheel is rota-ted. Check the tire pressure and, if necessary,restart the tire pressure loss warning system(Canada only) or the tire pressure monitor (USAonly).
Direction of rotation
Tires with a specified direction of rotation haveadditional benefits, e.g. if there is a risk of hydro-planing. These advantages can only be gained ifthe tires are installed corresponding to thedirection of rotation.
An arrow on the sidewall of the tire indicates itscorrect direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,dry and preferably dark place. Protect the tiresfrom oil, grease, gasoline and diesel.
Mounting a wheel
Preparing the vehicle
XStop the vehicle on solid, non-slippery andlevel ground.
XApply the electric parking brake manually.
XBring the front wheels into the straight-aheadposition.
XShift the transmission to position].
XSwitch off the engine.
