Volume and sound settings
You will find details on volume ( Y page 124)
and sound ( Y page 125) settings in the "At a

GWARNING
External video sources may have different
volumes, which can mean that system
messages such as traffic announcements and
navigation system announcements are much
louder. If necessary, please deactivate the
system messages or adjust their volume
manually.
i In some cases, the volume of the AUX
device may be quieter or louder, or the
usual maximum possible volume cannot be
reached. On some devices, it is possible to
adjust the volume separately. In this case,
start at a medium volume and increase it
gradually. This enables you to determine
whether the system is able to play the
music at high volume without distorting it.

AIRMATIC
Vehicle level
Important safety notes
Your vehicle regulates its height
automatically. All-round self-leveling ensures
the best possible suspension and constant
ground clearance, even with a laden vehicle.
When you drive fast, the vehicle is lowered
automatically to improve driving safety and to
reduce fuel consumption.
The following vehicle levels are possible:
R normal
R raised: the vehicle is raised by about 1.20 in
(30 mm) when compared with the normal
level
R lowered: the vehicle is lowered by about
0.40 in (10 mm) when compared with the
normal level
The "Normal" and "Raised" vehicle levels can
be set manually.
The "Lowered” vehicle level is set
automatically at speeds over 60 mph
(100 km/h).
Setting the vehicle level
Select the "Normal" setting for normal road
surfaces and "Raised" for driving with snow
chains or on particularly poor road surfaces.
Your selection remains stored even if you
remove the SmartKey from the ignition lock.
GWARNING
To help avoid personal injury, keep hands and
feet away from wheel housing area, and stay
away from under the vehicle when lowering
the vehicle chassis.
