WARNING
Do not open the hood if the engine has auto-stopped. Turn off the engine
by switching off the ignition before lifting the hood.
In certain situations, it may be advisable to turn the Start/Stop function
off.
To turn off Start/Stop, tap the
Start/Stop function button in the center display's Function view...
(Option/accessory.)
The vehicle's leveling control system adjusts the suspension and shock absorbers
automatically to help optimize comfort and control while driving...
Other information:
The Electronic Stability Control (ESC1) function helps the driver
avoid skidding and improves the vehicle's directional stability.
This symbol will be displayed in
the instrument panel when the system is intervening.
When the system has intervened to apply the brakes, a pulsing sound may be heard
and the vehicle may accelerate more slowly than expected when the accelerator pedal
is depressed...
The stability system (ESC1) is always activated and cannot be switched
off. However, the driver can select ESC Sport Mode, which offers more active
driving characteristics.
With the ESC Sport Mode sub-function selected, intervention from the system
is reduced and more lateral movement is permitted, giving the driver more control
of the vehicle than usual...
