Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 27). Panic alarm
X
To activate: press!button :for at
least one second.
An alarm sounds and the exterior lighting

X To deactivate: press!button :
again.
or
X Insert the key into the ignition lock.
or
X Press the KEYLESS-GO Start/Stop button.
The KEYLESS-GO key must be in the vehi-
cle.
i The panic alarm function is only available
in Mexico. Occupant safety
Important safety notes
The seat belts, together with SRS (Supple-
mental Restraint System), are complemen-
tary, co-ordinated restraint systems
(Y page 43). They reduce the risk of injury
in specific, pre-defined types of accident sit-
uations and thereby increase occupant
safety. However, seat belts and airbags gen-
erally do not protect against objects pene-
trating the vehicle from the outside.
To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 96)
R the seat belt has been fastened properly
(Y page 51)
R the airbags can inflate properly if they are
deployed (Y page 44)
R the steering wheel is adjusted properly
(Y page 96)
R the restraint systems have not been modi-
fied.
i An airbag increases the protection of
vehicle occupants wearing a seat belt.
However, airbags are only an additional
restraint system which complements, but
does not replace, the seat belt. All vehicle
occupants must wear their seat belt cor-
rectly at all times, even if the vehicle is
equipped with airbags. The airbags are not
deployed in all types of accidents. For
example, if the protective capacity of cor-
rectly fastened seat belts is not increased
by deploying the airbags, the airbags will
not deploy. Airbag deployment only pro-
vides increased protection if the seat belt
is worn correctly because:
R the seat belt helps to keep the vehicle
occupant in the best position in relation
to the airbag.
R in a head-on collision, for example, the
seat belt prevents the vehicle occupant 42
