WARNING
Child restraint anchorages are designed
to withstand only those loads imposed by cor‐
rectly fitted child restraints. Under no circum‐
stances are they to be used for adult seat
belts, harnesses or for attaching other items or
equipment to the vehicle. After using the child
restraints, the anchor fittings may need to be
folded down.◀
Mounting points The symbol shows the mounting point
for the upper retaining strap.
There are two mounting points for child re‐
straints with tether straps.
Guiding the retaining strap WARNING
If the upper retaining strap is used incor‐
rectly with the child restraint system, the pro‐
tective effect may be reduced. Danger of in‐
jury. Make sure that the upper retaining strap is
not routed to the upper attachment strap over
sharp edges, and that it is not twisted.◀

Notes
When the ignition is switched off, selector
lever position P will be automatically engaged,
if selector lever position D or R is engaged.
With the vehicle stationary and the engine shut
down, the ignition is switched off automatically
under the following circumstances:▷When locking, even with the low-beam
headlights switched on.▷Shortly before the battery is discharged so
that an engine start remains possible.▷When opening or closing the driver's door,
if the driver's belt is unfastened and the
low-beam headlights are switched off.▷When the driver's belt is unfastened, if the
driver's door is opened and the low-beam
headlights switched off.
After about 15 minutes without further opera‐
tion, low-beam headlights are changed over to
side lights.
Radio ready state
Activate radio ready state: when the engine is
running, press the start/stop button.
Individual electrical systems remain opera‐
tional.
The radio ready sate is automatically switched
off in the following situations:

▷After approximately eight minutes.▷When locking via the central locking sys‐
tem.▷Shortly before the battery is discharged so
that an engine start remains possible.
Radio readiness remains active when ignition
is switched off automatically, such as for
following reasons:
▷Opening or closing driver's door.▷Unfastening driver's seat belt.▷When low-beam headlights are automati‐
cally changed to side lights.
If engine is switched off and ignition is
switched on, radio ready state will be automati‐
cally activated when door is opened if light is
switched off or daytime driving lights are
switched on, when corresponding equipment
is fitted.
Engine start Notes DANGER
A blocked exhaust pipe or inadequate
ventilation can allow harmful exhaust fumes to
penetrate the vehicle. The exhaust gas con‐
tains carbon monoxide, which is colourless and
odourless, but highly toxic. In enclosed spaces,
the exhaust fumes can also build up outside
the vehicle. Danger of fatal injury. Keep the ex‐
haust pipe clear and ensure sufficient ventila‐
tion.◀
WARNING
An unsecured vehicle can start moving
and rolling away. Danger of accidents. Before
leaving the vehicle, secure it to prevent rolling
away.
Observe the following to ensure that the vehi‐
cle is secured against rolling away:
▷Engage the parking brake.▷Turn the front wheels into the direction of
the kerb on upward or downward gradi‐
ents.▷Additionally secure the vehicle on upward
or downward gradients, e.g. using a
wedge.◀
ATTENTION
Repeated start attempts or starting sev‐
eral times in quick succession means that fuel
is not combusted, or insufficiently so. The cat‐
alytic converter can overheat. Danger of dam‐
age to property. Avoid starting more than once
in quick succession.◀

where the action of the seat belts alone would
be insufficient.
Side airbag In a side-on crash, the side airbag supports the
body from the side in the chest and pelvic area.Head airbag
The head airbag supports the head in the

Notes on optimum protective effect of
the airbag
WARNING
If the seat position is wrong or the de‐
ployment area of the airbag is impaired, the air‐
bag system cannot provide the intended pro‐
tection, or may cause additional injuries when
it deploys. Danger of injury or life. Comply with
these notes for optimum protective effect.◀▷Keep your distance from the airbags.▷Make sure that vehicle occupants keep
their head away from the side airbag.▷Always grip the steering wheel on the
steering wheel rim. Keep you hands in the
3 o'clock and 9 o'clock positions to reduce
the risk of injury to hands or arms when the
airbag deploys.▷Make sure that the front-seat passenger is
sitting correctly, in other words with feet or
legs in the footwell, not resting on the
dashboard.▷Do not position any other persons, pets or
objects between the airbags and persons.▷Never attach any material to the airbag
covers with adhesive; never place material
over them or modify them in any way.▷Keep the dashboard and windscreen in the
area of the passenger's side free, for exam‐
ple do not attach adhesive foil or covers
and do not fit brackets for navigation devi‐
ces or mobile telephones.▷Do not use the front airbag cover on the
front passenger's side as a tray.▷Do not fit seat covers, cushions or other
objects not specifically suitable for seats
with integral side airbags to the front seats.▷Do not hang items of clothing such as
coats or jackets over the backrests.▷Do not modify individual components of
the system or its wiring in any way. This
also applies to the covers of the steering
wheel, the dashboard and seats.▷Do not dismantle the airbag system.
Even if all these notes are complied with, de‐
pending on the circumstances in which an ac‐
cident occurs, certain injuries as a result of
contact with the airbag cannot be entirely ruled
out.
The noise caused by the deployment of an air‐
bag may lead to temporary hearing loss for ve‐
hicle occupants sensitive to noise.
Operational readiness of the airbag
system
Notes WARNING
Individual components of the airbag sys‐
tem can be hot after triggering. Danger of in‐ jury. Do not touch individual components.◀
WARNING
Work carried out incorrectly can lead to a
failure, a malfunction or accidental triggering of
the airbag system. If there is a malfunction, the
airbag system might not trigger as intended in
an accident, in spite of the accident being of
the appropriate severity. Danger of injury or
life. Have the airbag system tested, repaired or
removed and scrapped by a Service Partner or a qualified specialist workshop.◀
Correct function When the ignition is switched on, the
warning light in the instrument cluster
briefly illuminates in order to show the
functional readiness of the entire airbag sys‐
tem and the belt tensioner.
Airbag system disrupted
