There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!
Do not warm up the engine with the vehicle
stationary. Drive off immediately. Avoid high
engine speeds and driving at full throttle until
the engine has reached its operating temper-
ature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
!
At low engine oil temperatures under 68 ‡
(+20 †), the maximum engine speed is limi-
ted in order to protect the engine. To protect
the engine and maintain smooth engine oper-
ation, avoid driving at full throttle when the
engine is cold.
Hybrid vehicles: make sure that you read the
separate operating instructions. Otherwise, you
may not recognize dangers.

General notes
All vehicles are equipped with a removable
Start/Stop button.
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 Smart-
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
the vehicle. This occurs, for example, when
starting the engine.
To start the vehicle without actively using the
SmartKey:
the Start/Stop button must be inserted in the
R
ignition lock.
the SmartKey must be in the vehicle.
