WARNING
The risk of serious injury can be reduced with the engine running or when starting the engine.
Never start or run the engine in unventilated or enclosed spaces. The exhaust fumes contain carbon
monoxide, an odourless and colourless toxic gas. Carbon monoxide can cause people to lose
consciousness. It can also cause death.
Never start or run the engine if oil, fuel or any other highly flammable fluids are under or near the
vehicle, or are leaking out of the vehicle, e.g. as the result of damage.
Never leave the vehicle unattended with the engine running, particularly if a gear or driving position
has been selected. The vehicle could move suddenly or something unexpected may happen that may
cause damage, fire and serious injuries.
Never use a start booster. Start boosters could explode and cause the engine to suddenly run at high
revs.
WARNING
Never leave the engine running if you leave the vehicle unattended, particularly if a gear or position
has been selected. The vehicle could move suddenly or something unexpected may happen that may
cause damage, fire or serious injuries.
WARNING
Start boosters could explode or cause the engine to suddenly run at high revs.
Never use a start booster.
NOTICE
The starter and the engine can be damaged if you attempt to start the engine while the vehicle is in
motion or if the engine is started again immediately after it has been switched off.
When the engine is cold, avoid high engine speeds, driving at full throttle and overloading the
engine.
Do not push start or tow start the vehicle. Unburnt fuel could damage the catalytic converter.
NOTICE
If the engine does not start, never use the starter with a gear selected and the vehicle key in the

Driving profile selection and 4MOTION Active Control
Introduction
This chapter contains information on the followingsubjects:
⇒ Setting a driving profile
⇒ Individually adapting a driving profile
⇒ Troubleshooting
By selecting different driving profiles, the driver can adapt the characteristics of the vehicle systems
to the current driving situation, the desired ride comfort and an economical driving style. The
adaptable vehicle systems include the running gear, engine management system or the air
conditioning system.
Different driving profiles can be selected depending on the vehicle equipment level. The effect on
the vehicle setup in the individual driving profiles varies according to the vehicle equipment.
The Comfort driving profile is available only for vehicles with adaptive chassis control (DCC).
The setting options available depend on the type of drive. Vehicles with front-wheel drive have
onroad driving profiles, while vehicles with all-wheel drive have additional offroad driving profiles
⇒ Setting a driving profile .
The driving profile can be changed when the vehicle is stationary or while driving ⇒ . After
selecting a driving profile, the vehicle settings (excluding engine settings) are switched to the new
driving profile immediately. When traffic conditions allow, briefly take your foot off the accelerator
to activate the newly selected driving profile for the engine also.
WARNING
Selecting a driving profile while the vehicle is in motion can distract you from the road and cause
accidents.
Some settings can be stored in the user accounts of the personalisation function and therefore
change automatically when the user account changes ⇒ Personalisation .
