Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale< will always illuminate
for 6 seconds to remind you and your
passengers to fasten your seat belts.
If the driver’s seat belt is not fastened
when the engine is started, an additional
warning chime will also sound for a
maximum of 6 seconds or until the driver’s
seat belt is fastened.
If after these 6 seconds the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) is not fastened
with both doors closed,
the seat belt telltale< remains
illuminated for as long as either the
driver’s or front passenger’s seat belt is
not fastened.
and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt
telltale< starts flashing and a
warning chime sounds with increasing
intensity for a maximum of 60 seconds
or until the driver’s and the
which exceed preset deployment
thresholds and in certain rollovers (win-
dow curtain air bags and ETD).
Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a frontal crash, your body would
move too far forward. That would in-
crease the chance of head and neck in-
juries. The seat belt would also apply too
much force to the ribs or abdomen,
which could severely injure internal or-
gans such as your liver or spleen.
Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, SmartKeys,
etc., as these might cause injuries.
Position the lap belt as low as possible
on your hips and not across the abdo-
m e n . I f t h e s e a t b e l t i s p o s i t i o n e d a c r o s s
your abdomen, it could cause serious in-
juries in a crash.
Never use a seat belt for more than one
person at time. Do not fasten a seat belt
around a person and another person or
other objects.
Seat belts should not be worn twisted.
In a crash, you wouldn’t have the full
width of the seat belt to distribute im-
pact forces. The twisted seat belt
against your body could cause injuries.
Pregnant women should also always use
a lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.
Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.
When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.

tions can only be set via COMAND.The following automatic climate control
functions can be operated via COMAND:
iThe components and operating principles of
COMAND can be found on (
page 81).
Warning!G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents can be very
hot or very cold (depending on the set tem-
perature). This may cause burns or frostbite
to unprotected skin in the immediate area of
the air vents.
Always keep sufficient distance between un-
protected parts of the body and the air
vents. If necessary, use the air distribution
adjustment (
page 246) to direct the air to
air vents in the vehicle interior that are not
in the immediate area of unprotected skin.
Warning!G
Follow the recommended settings for heat-
ing and cooling given on the following pages
and pages in the “Controls in detail” part
(
page 453) Otherwise the windows could
fog up, impairing visibility and endangering
you and others.

iThe active Bi-Xenon headlamps monitor
your steering angle and driving speed, then auto-
matically shift their beams to either side to bet-
ter follow the curvature of the road ahead,
increasing usable illumination over conventional
headlamps.
