Airbag system
 Introduction
This chapter contains information on the followingsubjects:
⇒ Types of front passenger front airbag system
⇒ Indicator lamp
⇒ Description and function of the airbags
⇒ Front airbags
⇒ Switching the front passenger front airbag on and off
⇒ Side airbags
⇒ Curtain airbags
⇒ Knee airbags
The vehicle is equipped with a front airbag for the driver and front passenger. The front airbags can 
provide front seat occupants with additional chest and head protection if the seat, seat belts, head 
restraints and, in the case of the driver, steering wheel are adjusted and used correctly. Airbags are 
meant only for additional protection. The airbags are not a substitute for seat belts. Seat belts must 
always be worn, even when the front seats are equipped with front airbags.
The intelligent technology of the proactive occupant protection system cannot overcome 
the laws of physics, and functions only within the limits of the system. Never let the extra 
convenience afforded by the proactive occupant protection system tempt you into taking 
any risks when driving. The system cannot prevent a collision. The system is not a 
substitute for the full concentration of the driver.
•Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road 
and traffic conditions.
•The system cannot detect objects in all situations.
•The proactive occupant protection system does not react to people, animals, objects 
crossing in front of the vehicle, or objects which are hard to make out.
•Reflective objects such as safety barriers, tunnel entrances, heavy rain and ice can 
impair the function of the proactive occupant protection system and thus prevent it 
from detecting a collision risk.
•Incorrect system activation can occur.
WARNING
Accidents and injuries can occur if the driver is distracted.
•Never change settings in the Infotainment system when the vehicle is in motion.
WARNING
Failure to observe illuminated warning lamps and text messages can lead to your vehicle 
breaking down in traffic, and can cause accidents and serious injuries.
•Never ignore any illuminated warning lamps or text messages.
•Stop the vehicle as soon as it is possible and safe to do so.
WARNING
Failure to observe illuminated indicator lamps and text messages can lead to your vehicle 
being damaged.
NOTICE 

•If the vehicle rolls over.
•If the speed in a collision is lower than the reference value specified in the control unit.
Front airbags

First read and observe the introductoryinformation and safety warnings⇒
Introduction
In conjunction with the seat belts, the front airbag system gives the front occupants additional 
protection for the head and chest in the event of a severe frontal collision. Always keep as far away 
from the front airbag as possible ⇒ Sitting position. This allows the front airbags to inflate fully 
when triggered, thus providing maximum protection.
The front airbag for the driver is located in the steering wheel ⇒ Fig. 44 and the front airbag for the 
front passenger is located in the dash panel ⇒ Fig. 45. The airbag locations are identified by the 
text AIRBAG.
The areas inside the red lines are covered by the front airbags when deployed (deployment zoneyf   
You must never leave or attach any objects in these areas ⇒. Any factory-fitted accessories will 
not be struck if the driver and front passenger front airbags are deployed.
Once triggered, the airbag inflates at high speed.
•Always leave the deployment zones of the front airbags clear.
•Never attach any objects, such as drink or telephone holders, to the covers of the 
airbag modules or anywhere in the airbag module deployment zone.
•No other people, animals or objects may be carried between the occupants of the front 
seats and the airbag deployment zone. Ensure that children and passengers keep to 
this rule.
•Do not attach any objects, e.g. mobile navigation devices, to the windscreen above the 
front airbag on the front passenger side.
•Do not cover or stick anything on the steering wheel hub or the soft plastic surface of 
the airbag unit in the dash panel on the front passenger side, and do not modify them 
in any way.
DANGER
The front airbags are deployed in front of the steering wheel ⇒ Fig. 44 and dash panel 
⇒ Fig. 45.
•When driving, always hold the steering wheel with both hands on the outside of the 
ring at the 9 o'clock and 3 o'clock positions.
•Adjust the driver seat so that there is at least 25 cm between your breastbone and the 
hub of the steering wheel. Contact a qualified workshop if your physical build makes 
this impracticable.
•Adjust the front passenger seat so that the distance between the passenger and the 
dash panel is as large as possible.
WARNING 

Closing the glass roof without the roll-back function
•Press the  button to the 2nd position Ⓓ until the glass roof has fully closed.
•The glass roof will now close without the roll-back function.
•Please go to a qualified workshop if the glass roof still cannot be closed.
If you let go of the switch during the closing procedure, the glass roof will open automatically.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Glass roof will not close
•The glass roof only works when the ignition is switched on. The glass roof can still be opened or 
closed for a short time after the ignition has been switched off, provided the driver door or front 
passenger door are not opened.

Fig. 78 On the steering wheel: 9 o'clock and 3 o'clock position.
Adjust the steering wheel position before setting off and only when the vehicle is stationary ⇒.
•Push down the lever ⇒ Fig. 77①.
•Adjust the steering wheel so that you can hold it with both hands at its circumference at the 9 
o'clock and 3 o'clock positions with your arms slightly bent ⇒ Fig. 78.
•Push the lever up firmly until it is flush with the steering column trim ⇒.
Closing the glass roof without the roll-back function can cause serious injuries.
•Always close the glass roof carefully.
•Ensure that nobody obstructs the path of the glass roof, especially if the roll-back 
function is not active.
•The roll-back function does not prevent fingers or other body parts from being pressed 
against the roof frame and sustaining injury.
WARNING 

Seats and head restraints
Front seats
 Introduction
This chapter contains information on the followingsubjects:
⇒ Mechanically adjusting the front seat
⇒ Electrically adjusting the front seat
⇒ Folding the front passenger seat backrest forwards
The following section describes the options for adjusting the front seats. Always ensure that the 
correct sitting position is adjusted ⇒ Sitting position.
Incorrect use of the steering column position adjustment and incorrect adjustment of the 
steering wheel can cause serious or fatal injuries.
•After adjusting the steering column, always move lever ⇒ Fig. 77① up so that it 
engages securely. This prevents the steering column from moving spontaneously 
while the vehicle is in motion.
•Never adjust the steering wheel when the vehicle is in motion. If you determine that a 
readjustment is necessary, stop the vehicle safely and adjust the steering wheel to the 
correct position.
•The steering wheel must always point towards the chest and not towards the face. This 
ensures that the driver front airbag provides maximum protection in the event of an 
accident.
•While driving, always keep both hands on the outside of the steering wheel at the 9 
o'clock and 3 o'clock positions⇒ Fig. 78. This reduces the risk of injury if the driver 
front airbag is triggered.
•Never hold the steering wheel at the 12 o'clock position, or in any other manner, e.g. on 
the hub of the steering wheel. If the driver front airbag is triggered, you could receive 
severe injuries to the arms, hands and head.
WARNING 

Mechanically adjusting the front seat
Always adjust the front seats to their correct position before any journey and ensure that 
any passenger has fastened their seat belt.
•Push the front passenger seat as far back as possible.
•Adjust the driver seat so that there is at least 25 cm between your breastbone and the 
hub of the steering wheel. Adjust the driver seat by moving it forwards or backwards 
so that you are able to press the pedals to the floor with your knees still slightly bent 
and so that the distance from the dash panel to your knees is at least 10 cm. If your 
build makes it impossible to fulfil this requirement then you must contact a qualified 
workshop so they can make any necessary modifications.
•Never travel with the backrest tilted far back. The further back the backrest is tilted, the 
greater the risk of injury caused by incorrect seat belt routing or an incorrect sitting 
position.
•Never travel with the backrest tilted far forwards. When a front airbag is triggered it 
could force the seat backrest backwards and injure vehicle occupants on the back 
seats.
•Adopt and maintain the greatest possible distance from the steering wheel and dash 
panel.
•You should always sit upright with your back against the seat backrest with the front 
seats properly adjusted. Do not position any body part too close where the airbags are 
fitted.
•The risk of serious injury is increased for passengers on the rear seat if they are not 
sitting upright because the seat belts are incorrectly positioned.
WARNING
Incorrect adjustment of the seats can cause accidents and serious injuries.
•Only adjust the seats when the vehicle is stationary. The seats could change position 
unexpectedly if you attempt to reposition them while the vehicle is in motion, leading 
to a loss of control of the vehicle. Furthermore, an incorrect seating position is 
adopted while adjusting the seat.
•Only adjust the height and tilt of the seat or move it forwards and backwards when the 
area around the seat is clear.
•To be able to make adjustments to the seats, the area around them must not be 
restricted by any items.
•Only adjust the height of the rear seat or move it forwards and backwards when the 
area around the seat is clear.
•The areas for adjusting and locking the seats must not be soiled.
WARNING
Improper use of seat covers or protective covers may lead to the electrical seat controls 
being operated accidentally and the front seats moving unexpectedly while the vehicle is 
moving. You could lose control over the vehicle. This could result in serious injury and 
accidents. Furthermore, this may result in damage to the electrical components in the 
front seats.
•Never attach or secure seat covers or protective covers to the electrical controls.
•Do not fit seat covers or protective covers over the seats unless they have been 
expressly approved for use in the vehicle.
WARNING
Cigarette lighters in the vehicle could be damaged or accidentally lit. This could lead to 
serious burns and other injuries.
•Before adjusting the seats always ensure that there is no lighter on or near the 
moveable parts of the seat.
•Before closing stowage areas or compartments always ensure that there is no lighter 
in the way.
•Never stow lighters in stowage areas, compartments or on other surfaces in the 
vehicle. High surface temperatures, especially in summer, may cause cigarette lighters 
to self-ignite.
