Curtain airbags
Fig. 49 On the left-hand side of the vehicle: location and deployment zone of the curtain airbag.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
In the interior, a curtain airbag is fitted above the doors on both the driver and front passenger sides
⇒ Fig. 49.
The curtain airbag locations are identified by the text AIRBAG.
The area in the red frame ⇒ Fig. 49 is covered by the curtain airbag when triggered (deployment
zone). For this reason, you must never leave or attach any items in this area ⇒.
In a side collision the curtain airbag is triggered on the impact side of the vehicle.
In a side collision, the curtain airbags reduce the risk of injury to the areas of the body facing the
impact for vehicle occupants on the front seats and outer rear seats.
Knee airbags
Once triggered, the airbag inflates at high speed.
•Always leave the deployment zones of the side airbags clear.
•Vehicle occupants sitting on the front seats and rear outer seats must never carry any
people, pets or objects in the deployment zone between themselves and the airbags.
Ensure that children and passengers keep to this rule.
•The built-in coat hooks should only be used for lightweight clothing. Do not leave any
heavy or sharp objects in the pockets.
•Do not fit any accessories to the doors.
•Do not fit seat covers or protective covers over the seats unless they have been
expressly approved for use in the vehicle. Otherwise the side airbag may not be able to
inflate once triggered.
WARNING
Incorrect use of the driver and front passenger seat could hinder the proper function of
the side airbag and cause serious injury.
•Never remove the front seats from the vehicle or alter any components of these seats.
•If too much pressure is applied to the backrest side bolster, the side airbags may not
be triggered correctly, may not trigger at all, or may trigger unexpectedly.
•Any damage to the original seat upholstery or around the seams of the side airbag
units must be repaired immediately by a qualified workshop.
WARNING
Once triggered, the airbag inflates at high speed.
•Always leave the deployment zones of the curtain airbags clear.
•Never secure any items to the cover or in the deployment zone of the curtain airbag.
•Vehicle occupants sitting on the front seats and rear outer seats must never carry any
people, pets or objects in the deployment zone between themselves and the airbags.
Ensure that children and passengers keep to this rule.
•The built-in coat hooks should only be used for lightweight clothing. Do not leave any
heavy or sharp objects in the pockets.
•Do not fit any accessories to the doors.
•Do not install any sun blinds onto the side windows unless they have been expressly
approved for use in your vehicle.
•Only push the sun blinds over to the side windows if no items are attached to them
(e.g. pens or the remote control for a garage door).

Central locking button: lock the vehicle.
Fold the key bit in and out.
Indicator lamp.
Indicator lamp
The indicator lamp in the vehicle key flashes when you press a button.
Press the buttons on the key only if the corresponding function is actually needed. Pressing
a button when the function is not required could lead to the vehicle being unlocked unintentionally
or the alarm going off. This also applies even when you are not within the effective range.
Changing the button cell
Swallowing batteries with a diameter of 20 mm, or other button cells, can result in severe
or even fatal injuries within a very short period of time.
•Always keep the vehicle key, key ring with batteries, spare batteries, round cells and
other batteries that are larger than 20 mm out of the reach of children.
•Call for medical help immediately you suspect that someone has swallowed a battery.
DANGER
Careless or unsupervised use of the vehicle key can lead to accidents or injuries.
•Always take all vehicle keys with you every time you leave the vehicle. Children or
unauthorised persons could lock the doors and the boot lid, start the engine or switch
on the ignition and operate electrical equipment such as the electric windows.
•Never leave children or people requiring assistance alone in the vehicle. They could
become trapped in the vehicle in an emergency and may not be able to get themselves
to safety. For example, locked vehicles may be subjected to very high or very low
temperatures depending on the season. This can cause serious injuries and illness or
fatalities, especially among small children.
•Never switch off the ignition while the vehicle is in motion. The steering column lock or
steering lock mechanism may be activated and you will no longer be able to steer the
vehicle.
WARNING
Every electric vehicle key contains electronic components. Protect the key from damage,
moisture and excessive vibration.

Please note that the sensor surfaces in the door handles could be activated by a powerful
jet of water or steam if a valid vehicle key is in the operating range at the same time. If at
least one window is open and sensor surface in a door handle is continuously activated,
all windows will close. It is possible that all windows will open if the jet of water or steam is
moved away from a door handle sensor surface briefly and then moved back onto it
⇒ Central locking system.
NOTICE
