2019 MERCEDES-BENZ CLA brake

!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.

If you press Start/Stop buttonConce whenin this position, the ignition is switched offagain.
Removing the Start/Stop button
You can remove the Start/Stop button from theignition lock and start the vehicle as normalusing the SmartKey.
You can only switch between Start/Stop buttonmode and SmartKey operation when the vehicleis stationary.
You must also engage park position].
XRemove Start/Stop buttonCfrom ignitionlockD.
You do not have to remove the Start/Stop but-ton from the ignition lock when you leave thevehicle. You should, however, always take theSmartKey with you when leaving the vehicle. Aslong as the SmartKey is in the vehicle:
Rthe vehicle can be started using the Start/Stop button

Driving tips
Changing gear
The automatic transmission shifts through theindividual gears automatically when it is in trans-mission position[. This automatic gear shift-ing behavior is determined by:
Rthe selected drive program
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts
