[I) Tips
• When defrosting/defogging the windows, air flows from outlets
(D ,@ and @. To defrost or defog the windows as rapidly as poss ible,
air outlets ® should be opened
fully with the adjuster wheels.
• When the air conditioner is working, cooled air w ill flow primarily
from outlets @,® and @. To assure adequate cooling, outlets ®
and © should never be completely closed.•
Using the climate controls economically
Using the climate controls prudently can help save fuel .
When you use the air conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should use
the air conditioner only when necessary. Also please note the
following points:
- If you want to save fuel, switch off the air conditioner .
- If you are going to drive with the windows open, switch off
the air conditioner.
By reducing the amount of fuel you use, you also reduce the amount
of polluta nts emitted into the air. •

Driving Safely ---------------------"~'---
Important things to do before driving
Safety is everybody's job! Vehicle and occupant safety
always depends on the informed and careful driver.
For your safety and the safety of your passengers, before
driving always:
- Make sure that all lights and signals are operating
correctly.
- Make sure that the tire pressure is correct.
- Make sure that all windows are clean and afford good visi-
bility to the outside.
- Secure all luggage and other items carefully::::>
page 91.
-Make sure that nothing can interfere with the pedals.
- Adjust front seat, head restraint and mirrors correctly for your height .
- Instruct passengers to adjust the head restraints according to their height.
- Make sure to use the right child restraint correctly to
protect children ::::,
page 167, "Child Safety".
- Sit properly in your seat and make sure that your passen­ gers do the same::::,
page 73, "General recommenda­
tions".
- Fasten your safety belt and wear it properly. Also instruct
your passengers to fasten their safety belts properly

What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted .
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
become a hazard to everyone else on the road::::,,& . There­
fore:
Do not let yourself be distracted by passengers or by using
a cellular telephone.
NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense .
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used.•

Child restraints on the front seat - some
important things to know
- Be su re to re ad t he i mpo rt a nt i nfo rmation a nd head the
WA RNINGS fo r i mporta nt details about chil dre n and
Advanced Airbags ~
page 167.
Even t hough your ve hicle is eq uipped with an Advanced Airbag
System, ma ke ce rtain that a ll chi ld ren, especia lly those 12 years an d
younger, always r ide in the back seat prope rly rest rained fo r th eir age
and si ze. The airbag on the passenger side makes the front seat a
po tentially da ngerous place fo r a child to r ide. The fro nt seat is not
the safest place for a ch ild in a forward-facing child safety seat. It can
be a very dange rous place fo r an i nfan t or a child in a rearward-fac ing
seat.
Th e Advanced Ai rbag System in your vehicle has been cer tified to
comply with the req uirements of Un ited States Federa l Moto r Veh icle
Sa fety Standard 208 as applicable at the time your vehicle was manu­
factured.
The Standard requires the front airbag on the passenger side to be
tu rne d off ("s uppressed") if a c hild up to abou t one ye ar of age
restra ined in o ne of the rear -facing or forward -fac ing infant
restra ints listed in Federa l Moto r Vehicle Safety Standard 208 with
whic h the Advanced Airbag System in yo ur vehicle was cert ified has
been installed on the front passenger seat. For a listing of the ch ild
restra in ts that were used to certify compliance with the US Saf ety
Standard =>
page 169.
The PASSENGER AIR BAG OFF ligh t in th e in st rume nt p anel t ells you
when the front Advanced A irbag on the passenger side has been
tur ned off by the ele ct ronic con trol uni t.
Each time you t urn on the ignition, t he
PASSENGER AIR BAG OFF
light will come on for a few seconds and:
• will stay on if th e front passenger se at is no t oc cupie d,
Controls and equip­

• will stay on if there is a small ch ild or child restra int on the front
p assenge r se at,
• will go off if the front passenger seat is occup ied by an adult as
reg iste red by t he weight -sens ing mat =>
page 156, "M oni tor ing t he
Advanced Airbag System" .
T he
PASSENGER AIR BAG OFF light comes o n when t he control unit
de tects a total weight on t he front passenger seat that req uires the
front airbag to be t urned off .
If th e total weight o n the front passenger seat is more than th at of a
typical 1 year-o ld child but less than the weight of a small adult, the
fr on t a ir bag on the passenge r si de c an deploy (t he
PASSENGER AIR
BAG OFF
light does not come on) . If the PASSENGER AIR BAG OFF
light does not come on, the front airbag on the passenger side has
not been turned off by the electronic co ntrol unit and can deploy if
the control unit senses an impact t hat meets the conditions stored in
its memory.
For example, the airbag may deploy if:
• a small child that is heavier than a typical 1 year -old child is on the
front passenger seat (regard less of whether the chi ld is in one of the
child safety seats listed =>
page 169), or
• a child who has outgrown child restraints is on the front passenger
sea t.
If the fro nt passenger a irbag is tur ned off, the
PASSENGER AIR BAG
OFF
lig ht comes on in the instr ument cluster an d stays on.
Th e fron t airbag on t he pa sse nger side may
not dep loy (t he

if a small a dult or teenager, o r a passenger who is no t sitti ng upright
with their back against a non-reclined backrest w ith the ir feet on the
vehicle floor in front of the seat is on the front passenger seat
=>

• Therefore, always wear your safety belts and make sure that
everybody in your veh icle is properly restrained .
& WARNING
A person on the front passenger seat , especially infants and small
c hildren, will receive seriou s injuries and can even be killed by
being too close to the a irbag when it inflates.
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front passenger a irbag if an infant or a
small child is on the front passenger seat, nobody can absolutely
guarantee that deployment under these special conditions is
impossible in all conceivable situations that may happen during
the useful life of your vehicle.
• The Advanced Airbag System can deploy in a ccordance with the
" low risk" option under the U.S. Federal Standard if a child that is
hea vier than the t ypical one-year old child is on the front
passeng er seat and the other condition s for airbag deployment
are met.
• Accident statistics have shown that children are generally safer
in the rear seat area than in the front seating position .
• For their own safety, all children , especially 12 years and
younger, should always ride in the back properly res trained for
their age and size. •
Advanced front airbag system
Your vehicle is equipped with a front Advanced Airbag System in

& WARNING
To reduce the risk of injury when an airbag inflates, always wear
safety belts properly .
• If you are unrestrained, leaning forward, sitting sideways or
out of position in any way, your risk of injury is much higher .
• You will also receive serious injurie s and could even be killed if
you are up against the airbag or too close to it when it inflates -
even with an Advanced Airbag~
page 145.
& 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 airbag inflates -even with an Advanced Airbag System .
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front airbag when a rearward-facing child
restraint has been installed on the front passenger seat, nobody
can absolutely guarantee that deployment is impossible in all
conceivable situations that may happen during the useful life of
your vehicle .
• The inflating airbag will hit the child safety seat or infant
c arrier with great force and will smash the child safety seat and
child against the backrest, center armrest , door, or roof.
• Always install rearward-facing child restraints in the back seat.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and the PASSENGER AIR BAG OFF light does not come on and stay on , _,.
