Very hot or very cold air can flow from the
air vents. This could result in burns or frost-
bite in the immediate vicinity of the air
vents. There is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
GWARNING
When AIRSCARF is switched on, very hot air
can flow from the vents in the head
restraints. This could result in burns in the
immediate vicinity of the air vents. There is a
risk of injury.
Reduce the heater output before it becomes
too hot.
In order to ensure the direct flow of fresh airthrough the air vents into the vehicle interior,please observe the following notes:
Rkeep the air inlet grille on the hood and inthe engine compartment on the front-passenger side free of blockages, such asice, snow or leaves.
Rnever cover the air vents or air intake grillesin the vehicle interior.

KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped witha SmartKey featuring an integrated KEYLESS-GO start function and a detachable Start/Stopbutton.
The Start/Stop button must be inserted in theignition lock and the SmartKey must be in thevehicle.
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 different 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.
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.
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 66).
Do not keep the SmartKey:
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 impair the functionality of the KEY-LESS-GO key.
If you lock the vehicle with the SmartKey'sremote control or with KEYLESS-GO, after ashort time:
Ryou will not be able to switch on the ignitionwith the Start/Stop button.
Ryou will not be able to start the engine withthe Start/Stop button until the vehicle isunlocked again.
The engine can be switched off while the vehi-cle is in motion by pressing and holding theStart/Stop button for three seconds. Thisfunction operates independently of the ECOstart/stop automatic engine switch-off func-tion.
