Booster seats and safety belts
Properly used booster seats con help protect
children weighing between about 40 lbs. and 80
lbs. (18 kg and 36 kg) who ore less than 4
ft. 9
in . (57 inches/1 .45 meters) tall .

The vehicle's safety belts alone will not fit most
children until they are at least 4
ft. 9 in . (57 in­
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children up so
that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
• Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a child on a booster seat.
• The shoulder be lt must lie as close to the cen­
ter of the child's collar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen . Make sure the
belt lies flat and snug . Pull on the belt to tight­
en if necessary.
• If you must transport an older child in a boos­
ter seat on the front passenger seat, you can
use the safety belt height adjustment to help
adjust the shoulder portion properly .

• Secure unused safety belts on the rear seat
r=;, page 172 .
Children up to at least 8 years old (over 40 lbs or
18 kg) are best protected in child safety seats de­
signed for their age and weight . Experts say that
the skeletal structure, particularly the pelvis, of
these children is not fully developed, and they
must not use the vehicle safety belts without a
suitable child restraint .
It is usually best to put these children in appro­
priate booster seats . Be sure the booster seat
meets all applicable safety standards.
Booster seats raise the seating position of the
child and reposition both the lap and shoulder parts of the safety belt so that they pass across
the child 's body in the right places. The routing of
the belt over the child 's body is very important
for the child's protection, whether or not a boos ­
ter seat is used. Children age 12 and under must
always ride in the rear seat.
Children who are at least 4
ft. 9 in. (57 inches/
1.45 meters) tall can generally use the vehicle's
three point lap and shoulder belts . Never use the
lap belt portion of the vehicle's safety belt alone
to restrain any child, regardless of how big the
child is. Always remember that childr en do not
have the pronounced pelvic structure required for
the proper function of lap belt portion of the ve­
hicle 's three point lap and shoulder belts. The
child's safety absolutely requires that a lap belt
portion of the safety belt be fastened snugly and
as low as possible around the pelvis . Never let
the lap belt portion of the safety belt pass over
the child's stomach or abdomen .
In a crash, airbags must inflate within a blink of
an eye and with considerable force . In order to do
its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu­
pant moves forward into the airbag .
A vehicle occupant who is out of position and too
close to the airbag gets in the way of an inflating
airbag . When an occupant is too close, he or she
will be struck violently and will receive serious or
possibly even fatal injury. .,..

In order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any children, who must be in the front seat be­
cause of exceptional circumstances, be properly
restrained and as far away from the airbag as
possible . By keeping room between the child's
body and the front of the passenger compart­
ment, the airbag can inflate completely and pro­
vide supplemental protection in certain frontal
collisions .
A WARNING
Not using a booster seat, using the booster
seat improperly, incorrectly installing a boos­
ter seat or using the vehicle safety belt im­
properly increases the risk of serious personal
injury and death in a collision or other emer­
gency situation. To help reduce the risk of se­
rious personal injury and/or death:
- The shoulder belt must lie as close to the
center of the child's collar bone as possible
and must lie flat and snug on the upper
body . It must never lie across the throat or
neck. The lap belt must lie across the pelvis
and never across the stomach or abdomen.
Make sure that the belt lies flat and snug.
Pull on the belt to tighten if necessary.
- Failure to properly route safety belts over a
child's body will cause severe injuries in an
accident or other emergency situation
¢ page 135.
-The rear side of the child safety seat should
be positioned as close as possible to the
backrest on the vehicle seat.
- For adjustable head restraints : adjust or re­
move the rear seat head restraint if it is dif­
ficult to install the child seat with the head restraint in place¢
page 56. Install the
head restraint again immediately once the
child seat is removed. Driving without head
restraints or with head restraints that are
not properly adjusted increases the risk of
serious or fatal neck injury dramatically .
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates.
- Never let a child stand or kneel on any seat,
for example the front seat.
-
Child safety
-Never let a child ride in the cargo area of
your vehicle.
- Always remember that a child leaning for­
ward, sitting sideways or out of position in any way during an accident can be struck by
a deploying airbag. This will result in serious
personal injury or death.
- If you must install a booster seat on the
front passenger seat because of exceptional
circumstances the
PASSENGER AIR BAG
OFF
light must come on and stay on, when­
ever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, perform the
checks described ¢

the Advanced Airbag System.
- Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the

Securing child seats
Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas­
senger can be locked with the convertible locking
retractor to properly secure child safety seats.
The safety belts emergency locking retractors for
the rear seats safety belts and for the front pas­
senger's seat safety belt have a convertible lock­
ing retractor for child restraints. The safety belt
must be locked so that belt webbing cannot un­
reel. The retractor can be activated to lock the
safety belt and prevent the safety belt webbing
from loosening up during normal driving. A child
safety seat can only be properly installed when
the safety belt is locked so that the child and
child safety seat will stay in place .
Always remember: Even though your vehicle is equipped with an Advanced Airbag system, all

Child safety
children, especially those 12 years and younger,
should always ride in the back seat properly re­
strained for their age and size.
A WARNING
Improperly installed child safety seats in­
crease the risk of serious personal injury and
death in a collision.
-
-Always make sure that the safety belt re­
tractor is locked when installing a child safe­
ty seat . An unlocked safety belt retractor
cannot hold the child safety seat in place
during normal driving or in a crash.
- Always buckle the child safety seat firmly in
place even if a child is not sitting in it . A
loose child safety seat can fly around during
a sudden stop or in a collision.
- Always make sure that the rear seat back­
rest to which the center rear safety belt* is
attached is securely latched whenever the
rear center safety belt is being used to se­
cure a child restraint.
- If the backrest is not securely latched, the
child and the child restraint will be thrown
forward together with the backrest and will
strike parts of the vehicle interior. The child can be seriously injured or killed.
- Never install rear-facing child safety seats or
infant carriers on the front passenger seat.
A child will be seriously injured and can be killed when the passenger airbag inflates.
- The inflating airbag will hit the child safety seat or infant carrier with great force and
will smash the child safety seat and child against the backrest, center armrest, door
or roof.
- Always install rear-facing child safety seats
or infant carriers on the rear seat .
- Forward-facing child safety seats or infant
carriers installed on the front passenger's
seat may interfere with the deployment of
the airbag and cause serious injury to the child.
- It is safer to install a forward-facing child
safety seat on the rear seat.
- Always read and heed all WARNINGS when­
ever using a child restrained in a vehicle is
being used

restraints on the front seat -some impor­
tant things to know.
A WARNING
Always take special precautions if you must
install a forward or rearward-facing child re­
straint on the front passenger's seat in excep­
tional situations:
- Whenever a forward or rearward-facing
child restraint is installed on the front pas­
senger seat, the
PASSENGER AIR BAG OFF
light must come on and stay on whenever
the ignition is switched on.

the Advanced Airbag System.
- Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the
PASSENGER AIR
BAG OFF
light does not stay on whenever
the ignition is switched on.
- Improper installation of child restraints can
reduce their effectiveness or even prevent
them from providing any protection.
- An improperly installed child restraint can interfere with the airbag as it deploys and
seriously injure or even kill the child .
-Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
- After checking to make sure that the child
restraint is properly installed, make certain
that the child restraint is correctly recog­
nized by the capacitive passenger detection
system in the front passenger seat and that
the
PASSENGER AIR BAG OFF light signals
the correct front passenger frontal airbag
status.

has been designed and certified by its man­
ufacturer for use on a front seat with a
passenger front and side airbag .
- Never pu t the forward-facing child restraint
up, aga inst or very near the ins trument pan­
el.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possib le befo re installing the for­

back or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time . Some convenience functions,
such as interior lighting or power seat adjust­ ment, may not be available under certa in circum­
stances . These convenience functions will be
available aga in once you switch the ignition on
and start the engine.
With the engine switched off
The battery will drain if you use functions such as
listening to the rad io while the engine is switched
off.
The vehicle's ability to start may be impaired by
the energy use, a message w ill appear in the In­
fotainment system d isp lay.
The message indicates that the system will
switch off automatically soon. If you would like
to continue using the funct ions, you must start
the eng ine.
With the engine running
Although electrical energy is generated whi le
driving, the battery can drain. This can happen
when little energy is generated, and much is used
and the charge level of the battery is not optimal.
To restore the balance of energy, components
that require large amounts of energy are tempo­
rarily sca led back or switched off . Heating sys­
tems in particu lar require a great deal of energy .
If you notice, for example, that the seat heating*
or rear window defroster is not working, then it
has been tempo rar ily reduced or sw itched off .
These systems are available again as soon as the
ene rgy balance has been restored.
In addition, you may notice that the idle speed
h as slightly increased . That is normal and no
cause for concern. Due to the increased idling
speed , the additional required energy w ill be gen ­
e rat ed and the battery will be charged.

Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
~ Shut the engine off when you are not driving
the vehicle.
~ Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automatically reduced for
veh icles with the Start-Stop-System . It is effi­
cient to switch off the engine in vehicles without
the Start-Stop-System when stopped at railroad
crossings and long red lights. Turning the engine
off for just 30-40 seconds saves more fuel than is
burned by starting the engine again.
It takes a long time for the engine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially high when
the engine is warm ing up. So you shou ld drive
away as soon as you start the engine and avoid
running at high rpms while the engine is still
warming up .
(D Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling a lso produces
heat, wh ich could resu lt in overheating or oth­
er damage to the vehicle or other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
~ Have your vehicle serviced at regular intervals.
By having your vehicle regularly serviced by an
Aud i dea ler helps to ensure that it runs properly
and economica lly. The condition of your vehicle
not only affects its safety and ability to hold its
value, it a lso affects fuel consumption .
Check your oil each time you fill your tank.
The amount of oil used is related to engine load
and speed.
Driving and the environment
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certain mile­
age has been driven.
You must drive your veh icle about 3,000 miles
(5,000 kilometers) before you can properly as ­
sess oil consumption .
T h is also applies to fuel consumption and engine
o ut put .
CD Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let . Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the em ission contro l system and
cou ld lead to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, sw itches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other important vehicle components .
Fewer short trips
Fuel consumption will always be relatively high
on short trips .
~ Try to avoid dr iv ing short distances w ith a co ld
eng ine .
The engine and cata lytic converter have to reach
their optimal operating temperature to reduce
fuel consumpt ion and nox ious em issions effec­
t ively.
Just after starting, a co ld engine in a mid-size car
only achieves a fuel economy of 6-8 mi les per
gallon (30-40 l/100 km) . After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km). After about
2.5 miles (4 km), the eng ine is
at its proper operating temperature and fuel
economy has reached a norma l level. So you can
see that you should avoid short trips whenever
poss ible. .,.

(www.toptiergas.com).
The recommended gasoline octane rating for
your engine can a lso be found on a label located
on the ins ide of the fue l filler flap. This ra ting
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regula r gasol ine with a minimum octane rat­
ing of 87 AKl/91 RON. However, using 87 AKl/91
RON octane fue l will slight ly reduce eng ine per­
for mance.
Use unleaded ga soline only. Unleaded gasoline
is available th roughout the USA, Canada, and in
most European cou ntries. We recommend t hat
you do not ta ke yo ur vehicle to a reas or coun tries
where unlea ded gaso line may no t be ava ilab le.

The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
¢ page 210 .
Your vehicle fuel tank has an on board refuelling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and polluting the environment while you refue l your
vehicle. In order to fill the tank properly whi le
protec ting the environment, please follow this
refueling procedure carefully.
8_ WARNING
Under normal operating conditions, neve r ca r­
ry additional fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mowe r, snow blower, etc.,
be very careful and always observe loca l and
state laws rega rding the use, transportation
and storage of such fuel containers. Make cer­
tain the con tainer meets industry standards
(ANSI/ASTM F852 -86).

To avoid fuel spilling or evaporating from the fuel
tank always close fuel filler cap properly and
completely. An improperly closed fuel filler cap
may also cau se the MIL lamp¢

on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns .
- Fuel is highly flammable and can cause se­
vere burns and other injuries .
- Failure to shut the engine off while refuel­
ing and/or to insert the pump nozzle fully
into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow . Fuel
spray and overflowing fuel can cause a fire .
- Never use a cellular telephone while refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire.
-
-Never get back into your vehicle while refu­
eling.
If in exceptional circumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch metal to discharge static electric­
ity before touching the filler nozzle again.
Static electricity can cause sparks that can ignite fuel vapors released during refueling.
- Never smoke or have an open flame any­ where in or near your vehicle when refueling
or filling a portable fuel container.
- For your safety, we strongly recommend that you do not travel with a portable fuel container in your vehicle . The container, full
or empty may leak and could cause a fire,
especially in a crash .
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container while it
is anywhere in or on the vehicle (for exam­
ple, in the luggage compartment, or on
the trunk). Static electricity can build up while filling and can ignite fuel vapors
causing a fire.
- Always place a portable fuel container on
the ground before filling.
Fuel and Refueling
- Always keep the filler nozzle completely
inside the portable container before and
during filling.
- If filling a portable container made of
metal, the filler noz zle must always be in
contact with the container. This will help prevent static electricity from discharging
and cause a fire.
- Never spill fuel inside the vehicle or lug­
gage compartment . Fuel vapors are highly
flammable.
- Always observe local and state/provincial laws regarding the use, storage and trans­
portation of fuel containers.
- Make certain the fuel container meets in ­
dustry standards (ANSI/ ASTM F852 -86) .
(D Note
If any fuel has spilled onto the car, it should
be removed immediately to prevent damage
to the paint.
@) For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first time,
the tank is full. Do not try to add more fuel
because fuel may spill out . In addition, the
expansion space in the fuel tank will be filled -
causing the fuel to overflow when it becomes
warm and pollute the environment.
(D Tips
- Running your engine while refuelling may
cause vapors to escape or even cause fuel to
spill out of the tank. This would then shut
off the fuel nozzle before the tank is full.
- Do not refuel your vehicle with the ignition
switched on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling.
- Diesel vehicles* are equipped with a diesel
misfueling protector. It allows the vehicle to
be fueled only with a diesel fuel pump noz­
zle . A worn or damaged nozzle or a nozzle
that is too small may not be able to open
the diesel misfueling protector. If this is the .,..
