61 Safety and Security
Occupant safety
Driver and passenger airbags are deployed 
in the event of a frontal impact
if impact exceeds a preset deployment 
threshold
independently of the side impact air-
bags
The airbags will not deploy in impacts 
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.
The front passenger airbag will only be de-
ployed if
the front passenger seat is occupied
the
7
 indicator lamp in the center 
console is not lit (
page 67)Side impact airbags, window curtain 
airbags
3Side impact airbags
4Window curtain airbag
The side impact airbags and window cur-
tain airbags are deployed
on the impacted side of the vehicle
in impacts exceeding a preset deploy-
ment threshold
independently of the front airbagsThe front passenger side airbag will only 
deploy if the system senses that the front 
passenger seat is occupied.
The side impact airbags are not deployed 
in impacts which do not exceed the sys-
tem’s deployment threshold.
Seat belts
The seat belt nonusage warning lamp
<
 
in the instrument cluster lights up and a 
warning sounds for a short time when you 
turn the key in the starter switch to 
position2 and the driver‘s seat belt is not 
fastened.
After starting the engine the seat belt non-
usage warning lamp blinks for a brief peri-
od to remind the driver and passengers to 
fasten the seat belts.
!Do not place objects heavier than 
20 lbs (9 kg) on the front passenger 
seat. This could cause the front or side 
impact airbag on the front passenger 
side to deploy in a crash which exceeds 
the system's deployment threshold.
