More important things to know about front
airbags
F ig. 238 Inf lated fro nt a irbags
Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold prope rly and provide sup­
p lemental pro tection in a frontal collision.
The front airbags are designed to provide add i­
tional protect ion for the chest and face of the
d river and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so that the oc -
cupant is properly seated as far as possible
from the airbag,
- and for adjustable head restraints: the head re-
straints have been properly adjusted.
Because airbags inflate in the blink of an eye with
g reat fo rce, things you have on your lap or have
p laced on the seat cou ld become dangerous pro­
jectiles, and be pushed into you if the airbag in­
flates .
W hen an airbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
veh icle. This dust is made up mostly of a powder
used to lubricate the airbags as they deploy . It
could irr itate skin .
It is important to remember that whi le the sup ­
p lemental a irbag system is designed to reduce
the likelihood of ser ious injuries, other injuries,
for example swel ling, bruising and minor abra -
Airbag system
sions, can also happen when airbags inflate . Air­
bags do not protect the arms or the lower parts
of the body. Front airbags supp lement the three ­
po int safety belts only in some frontal collisions
in which the vehicle dece leration is high enough
to dep loy the airbags .
Front airbags will not depl oy :
- if the ignition is switche d off when a crash oc-
curs,
- in side co llisions,
- in rear -end co llisions,
- in rollovers,
- when the crash decele ration measured by the
airbag system is less than the m inimum thresh­
old needed for airbag dep loymen t as registe red
by the electronic con trol un it.
The front passenger airbag also w ill not
deploy:
- when the fron t passenger seat is not occupied,
- when the e lectr ica l capacitance measured by
the capacit ive passenger detection system for
t he front passenge r seat ind icates that the pas­
senger side frontal airbag must be switched off
by the e lectronic control unit (the

light c::> page 281 and how they
work comes on and stays on).
A WARNING
Sitting in the wrong position can increase the
risk of ser ious injury in crashes.
- To reduce the r isk o f injury when the airbags
inflate, the driver and passengers must al­
ways sit in an upright posit ion, m ust not
lean aga inst or place any part of their body
too close to the area where the airbags are located.
- Occupants who are unbelted, out of position
or too close to the airbag can be serio usly
i n jur ed by an airbag as it unfolds with g reat
for ce in the blink of an eye

A WARNING
-Never open the hood when there is steam or
coolant escaping from the engine compart­
ment, because there is a risk that yo u could
be burned. Wait unt il no steam or coolant is
escaping.
- For safety reasons, the hood m ust always be
closed securely while driv ing. Because of
this, always c hec k t he hood after closing i t
to make sure it is latched correctly. The
hood is latched if the front corners cannot
be lifted.
- If you no tice that the hood is not latched
while you are driving, stop immediate ly and
close it, because driving when the hood is not latched increases the risk of an accident .
-If the hood is not latched comp letely, it
