Airbag syste m
safety seat. It can be a very dangerous p lace for
an infant or a child in a rearward-facing seat.
The Advanced Airbag System i n your veh icle has
been ce rt ified to comp ly with the requirements
of United States Federal Motor Vehicle Safety
Standard (FMVSS)
208, as well as Canada Motor
Veh icle Safety Standard (CMVSS)
208 as applica ­
b le at the time your vehicle was manufactured.
According to requirements, the front Advanced
Airbag System on the passenger s ide has been
certified for "suppression " for infants of about
12 month old and younger and for "low risk de­
p loyment " for children aged
3 to 6 years o ld (as
defined in the standard).
The
PA SSENGER AIR BAG OFF light in the instru­
ment panel tells you when the front Advanced
Ai rbag on the passenger side has been tu rned off
by the elect ronic cont rol unit.
Each t ime you tur n on the ignit ion , the
PASSEN­
GER AIR BAG OFF
light will come on fo r a few
seconds and :
- will stay on if the front passenger seat is not
occupied,
- will s tay on if there is a small c hild or child re­
straint on the front passenger seat,
- will go off if the front passenger seat is occu­
pied by an adult as reg istered by the weight ­
sensing mat¢
page 158, Monitoring the Ad­
vanced Airbag System .
The PAS SENGER AIR BAG O FF light comes on
when the control unit detects a total we ight on
the front passenger seat that requires the front
airbag to be turned off.
If the tota l weight on the front passenger seat is
more than that of a typical 1 year -old child but
less than the we ight of a small adult, the front
a irbag on the passenger side can deploy (the
PAS SENGER AIR BAG OFF light does not come
on) .
If the PAS SENGER AIR BAG OFF light does
not come on, the front a irbag on the passenger
side has not been turned off by the electronic
control unit and can deploy if the control unit
senses an impact that meets the condit ions stor ­
ed in its memory.
For e xample, the airbag may deploy if:
150
- a small chi ld that is heavier than a typica l 1
year-o ld child is on th e front passenger seat
(regard less of whether the child is in one of the
child safety seats listed¢
page 170), or
- a child who has outgrown c hild restraints is on
the front passenger seat.
If the front passenger a irbag is t urned off, the
PASSENGER AIR BAG OFF light comes on in the
instrument cluster and stays on.
The fro nt airbag on the passenge r side may
not
deploy (the PAS SENGER AIR BAG OFF light does
not ill uminate and stay lit) even if a small adu lt
or teenager, or a passenger who is not sitting up­
right with thei r back against a non-recl ined back­
rest with the ir fee t on the vehicle floor in front of
the sea t is on the fron t passenger sea t
<=> page 132, Proper seating position for the driv ­
er .
If the front passenger a irbag deploys, the Feder­
al Standard requires the airbag to meet the "low
risk" deployment cr iteria to reduce the r isk of in ­
jury through interaction w ith the airbag . "low
risk " deployment occurs in those crashes that
take place at lowe r de cele rations as defined in
the e lec tronic co ntro l unit ¢
page 159, PASSEN­
GER AIR BAG OF F light.
Always remembe r, a chi ld safety seat or infant
c ar rie r ins talled on the front seat may be s truck
and knocked ou t of posit ion by t he rap idly i nflat­
i ng passenge r's airbag in a frontal coll is ion . The
airbag could greatly red uce the effectiveness of
the child restraint and even seriously injure the child during inflation.
Fo r th is reason, and beca use the back seat is the
safest place for children -when properly restrain ­
ed according to their age and size -we strongly
recommend that children always sit in the back
seat
c> page 168, Child safety .
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the front
a ir bag inflates - even with an Advanced Airbag
Sys tem.

passenger seat is checked by the electronic con­
tro l unit when the ignition is on . The control unit
monitors the Advanced A irbag System and turns
the airbag indicator light on when a malfunct ion
in the system components is detected. The func­
tion of the airbag indicator l ight is descr ibed in
greater detai l below . Because the front passen­
ge r seat conta ins important parts of the Ad­
vanced A irbag System, you must take care to p re ­
ve nt i t from being damaged. Damage to the seat
may prevent the Advanced Airbag for the fron t
passenger seat from doing its job in a crash.
The front Advanced Airbag System consists
of the following :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An e lectronic control unit, with integrated
crash sensors for front and side impacts. The
control unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit a lso "de­
c ides" whether the safety belt pretens ioners
should be activated .
- An Advanced Airbag with gas generator and
control
valve for the driver ins ide the steer ing
wheel hub .
- An Advanced Airbag with gas generator and contro l
valve inside the instrument pa nel for
the front passenger.
- A weig ht-sensing mat under the upho lstery
padd ing of the front passenge r seat cushion
t h at meas ures the total weight on the seat. The
i nforma tion registered is sent continuously to
the e lectron ic cont rol unit to reg ulate dep loy­
ment o f the front Adv a need A irbag on the pas­
senger side .
- An airbag monito ring system and indicator
li ght in the instrument cluster
¢ page 158.
-A senso r in eac h front sea t registers the dis­
tance between the respective seat and the
steering wheel or instrument pane l. The infor­
mation reg istered is sent contin uously to the
electronic control unit to regulate deployment
of the front Adva need A irbags.
Airb ag sys tem
-The PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
pane l¢
page 159, fig . 167 and te lls yo u when
the front Advanced Airbag on the passenger side has been turned off.
- A sensor below the safety be lt latch for the
front seat passenger to measure the tension on the safety belt. The tension on the safety belt
and the we igh t registered by the weight -sens­
ing mat help the contro l unit "decide" whethe r
t he front airbag fo r th e fron t passe nger seat
should be tu rned off o r not ¢

whether tha t safety be lt is la tched o r not and
transmits this information to the e lectronic
control un it.
A WARNING ,-
Damage to the front passenge r seat can pre-
vent the front airbag from working properly.
- Improper repair or disassembly of the front
passenger and driver seat will p revent the
Advanced A irbag System from f unct ion ing
properly .
- Repairs to the front passenger seat must be
performed by qualified and p roper ly trai ned

- Never remove the front passenger or d river
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never d isassemble o r remove parts from the
seat or disco nnect w ires from it.
- Never carry sharp objects in your pockets or
p lace them on the seat . If the weight-sens­
ing mat in the passenger seat is punctu red
it cannot work p roper ly .
- Never carry things on your lap or carry ob­
jects on the passenge r seat . S uch items can

Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts.
In order to provide effective lub rication and cool ­
ing of internal engine components, all internal
combust ion engines consume a certa in amount
of oil. Oil consumption var ies from engine to en­
gine and may change significantly over the life of
the engine . Typically, engines w ith a specified
break-in period (see
c::;,page 194) consume more
o il dur ing the break-in per iod than they consume
after o il consumption has stabi lized .
Under normal cond itions, the rate of oil con­
sumption depends on t he quality and viscos ity of
the oil, the RPM (revolutions per m inute) at
wh ich the engine is operated, the ambient tem­
perature and road condit ions. Furthe r facto rs a re
t h e amount of o il d ilution from water condensa­
tion or fue l residue and the oxidation level of the
oi l. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unt il replacement of worn components may
become necessary.
With a ll these variab les coming into p lay, no
standard rate of oi l consumption can be estab­
li shed or spec ified . There is no alternative to reg­
ular and frequent checking of the oi l level, see
Note .
If the yellow engine oil level warning symbo l in
the instrument cluster
Ill lights up, you should
check the o il level as soon as possible
<=:> page 221 . Top off the o il at your earliest con­
venience
