tires. Note the following information for efficient  
and environmentally-conscious driving:  
Danger of rolling away! P not possible.  
Please apply parking brake  
Turn off electrical equipment that is not need-  
ed, for example seat heating*.

Breaking in  
Utilize the engine braking effect.  
Avoid driving short distances when possible.  
A new vehicle must be broken in within the first  
1,000 miles (1,500 km) so that all moving parts  
work smoothly together, which helps to increase  
the service life of the engine and other drive com-  
ponents.  
Tips  
The amount of noise produced by the vehicle  
can increase significantly when driving with a  
sporty style. Show respect to others around  
you and the environment with the way you op-  
erate your vehicle, especially at night.  
Do not drive higher than two-thirds of the maxi-  
mum permitted engine RPM during the first 600  
miles (1,000 km) and do not use full accelera-  
tion. The engine can be increased RPM gradually  
during the next 300 miles (500 km).

Driving  
Energy management  
Start/Stop system  
Your vehicle is equipped with an intelligent ener-  
gy management system for distributing electrici-  
ty. This significantly improves the starting ability  
and increases the vehicle battery life.  
Description  
Applies to: vehicles with Start/Stop system  
The Start/Stop system can help increase fuel  
economy and reduce CO emissions. In Start/  
2
Stop mode, the engine shuts off automatically  
when stopped, for example at a traffic light.  
Tips  
If you drive short distances frequently, the  
vehicle battery may not charge enough  
while driving. As a result, convenience func-  
tions for electrical equipment may be tem-  
porarily unavailable.  
If certain conditions are met, the engine may  
stop before the vehicle has come to a complete  
stop. If you press the accelerator pedal when this  
happens, the engine will start and driving power  
will be transmitted.  
The vehicle battery will gradually drain if  
the vehicle is not driven for long periods of  
time, or if electrical equipment is used  
when the engine is not running. To ensure  
that the vehicle can still be started, the  
electrical equipment will be limited or  
turned off.  
The ignition and important assist systems such  
as the brake booster will remain available during  
the Stop phase. The engine will restart automati-  
cally when needed.  
The Start/Stop system is automatically activated  
once the ignition is turned on.  
Messages

The button is located in front of the transmis-  
sion selector in the center console. The button  
will be illuminated when the function is turned  
off.
