The vehicle's safety belts alone will not fit most children until
they are at least 4 ft. 9 in. (57 inches/1.45 meters) tall and
weigh about 80 lbs. (36 kg). Booster seats raise these chil­
dren 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. •

Child Safety Ill
-------------------"'---
& WARNING (continued)
• 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.
• 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 arm rest, door or roof.
• Always be especially careful if you must install a rearward
facing child safety seat on the front passenger seat in exceptional
circumstances.
• A tight tether strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure on
the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy
the Advanced Airbag when it must be suppressed causing serious
or even fatal injury to the child.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, immediately install the rearward-facing child safety seat
in a rear seating position and have the airbag system inspected by

Activating the convertible locking retractor
Use the convertible locking retractor to secure a child
restraint.
Always heed the child safety seat manufacturer 's instruc­
tions when installing a child restraint in your vehicle. To acti­
vate the convertible locking retractor:
- Place the child restraint on a seat, preferably on the rear
seat .
Controls and equip­
ment Safety first Vehicle operation
-
Slowly pull the belt all the way out.
-Route it around or through the child restraint belt path
=>& .
- Push the child safety seat down w ith your full weight to
get the safety belt really tight .
- Insert the belt tongue into the buckle for that seating
position.
- Guide the safety belt back into the retractor until the belt
lies flat and snug on the child safety seat.
- You should hear a "clicking" noise as the belt winds back
into the inertia reel. Test the convertible locking retractor
by pulling on the belt. You should no longer be able to pull
the belt out of the retractor. The convertible locking
retractor is now activated.
- Make sure that the red release button is facing away from
the child restraint so that it can be unbuckled quickly.
- Pull on the belt to make sure the safety belt is properly
tight and fastened so that the seat cannot move forward
or sideways more than one inch (2.5 cm).
& WARNING
Using the wrong child restraint or an improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety 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 crash.

vi dual components. It regulates consumption, so that more electrical
energy is not being used than is being generated and ensures an
optimal state of charge for the battery .
[I] Tips
• But even energy management cannot negate the limits of physics.
Consider that the power and life of a battery are limited.
• If starting ability is threatened, you are informed by a warning
~ page 249, "Driver notification in the instrument cluster display" .•
What you should know
The highest priority is given to maintaining starting capa ­
bility.
Th e battery is severe ly taxed in short-distance driving, in city traffic
and during the cold time of year. Abundant electrical energy is
required, but only a little is generated.
It is also critical if the engine
is not running and electrical components are turned on. In this
instance energy is being consumed but none is being generated.
It is in prec ise ly these sit uations that you will notice energy manage­
ment actively regulating the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of several days or weeks,
electrical components are gradually cut back or sw itched off. This
reduces energy consumption and maintains starting capability over a
longer period.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remo te key or power seat adjust­
ment, may not be available. The convenience functions will be avail­
able again when you turn on the ignition and start the engine.
W ith the engine turned off
If you listen to the radio, for example, with the engine turned off or
use other MMI functions, the battery is being discharged .
If starting capability is jeopardized due to energy consumption, the
following warning appears in the MMI display:
Please start engine, otherwise system will switch off in
3 minutes.
Th e warn ing indicates that the system will be turned off automati­
cally after 3 m inutes. If you wish to continue using the functions, you
have to start the engine.
With the engine running
Although electrica l energy is generated when the vehicle is being
driven, the battery can become discharged. This happens most ly
when little energy is being generated and a great deal consumed and
the battery's state of charge is not optimal.
T o br ing the ene rgy balance back into equilibrium, consumers which
require especially large amounts of energy are temporarily cut back
or switched off. Heating systems in particular require a great deal of
energy .
If you notice, for example, that the heated seats* or the
heated rear window are not heating, they have been temporarily cut
back or switched off. These systems will be ava ilable again as soon as
the energy ba lance has been restored.
You will also notice that engine idle speed has been increased
slightly. This is normal and not a cause for concern. By increasing
eng ine id le speed the additional energy required is generated and the
battery is charged. •

Driver notification in the instrument
cluster display
If battery power drops into the range where it can limit the ability of
the engine to start, this is shown in the instrument cluster display
with the following driver message:
Lo w b attery charge : batt ery will be charged while driving
Th is notification rem inds you that the starting capability of the
engine may be limited . As soon as you start driving again, the batte ry
w ill be recharged and the notification w ill go out.
Dri ver notification appears and goes out again
If th is dr iver notification appears after the ignition is turned o n or
while driving a nd it goes out again afte r a w hile, the battery has been
adequate ly recharged.
Driver no tification appears and does not go out
again
If th is dr iver notifica tion appears afte r the ignition is turned o n or
while driving and does not go out again, the battery 's state of charge
is not in the optimal range . Starting ability is restricted. Have the
battery checked as soon as poss ible by an au thor ized Aud i dea le r o r
qualified workshop. •

Driving and environment
- Never put too much motor oil in your engine=> page 284,
"Adding engine oil~".
- Never try to pus h- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean-up" dev ice built into the
exhaust system of the vehicle. The catalytic converter burns many of
the pollutants in the exhaust gas before they are released into the
atmosphere.
T he exclusive use of unleaded fuel is c riti cal ly import ant for the life of
the catalytic converter and proper funct io ni ng of the eng ine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust sy stem may come in conta ct with dry gras s, brush, fuel
spill or other material which can cause a fire.
• Do not apply addit ional undercoat ing or rustproofing on or
near the exhaust manifold , exhau st pipes , catalytic converte r or
heat shield s. During driving, the sub stan ce u sed f or under coating
c ould o ve rheat and cause a fire.

• Do not exceed the correct engine oil level =>
page 284.
• Do not dr ive until the f uel tank becomes com plete ly empty . T he
engine could misfire . Unburned fuel cou ld also get into the ex ha ust
system and t his co ul d cause t he ca talyt ic converter to ove rheat .
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle u nder these conditions, as
otherwise f uel can reac h the c ata ly tic conve rter. This co uld res ult in
over heat ing of the converter, requir ing its replacement.

Driving and environment
The amount of oil used is related to engine load and speed.
It is normal for the oil consumption of a new engine to reach its
lowest value after a certain mileage has been driven.
You must drive your vehicle about 3,000 mi les (S,000 kilometers)
before you can properly assess oil consumption.
Th is also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with the
service recommendations in your Warranty
& Maintenance booklet.
Lack of proper maintenance as well as improper use of the vehicle w ill
impair the function of the emission control system and could lead to
damage.
• Do not alter or remove any component of the Emission Control
System unless approved by the manufacturer.
• Do not a lter or remove any device, such as heat shields, switches,
ignition wires, valves, which are designed to protect your vehicle's Emission Contro l System and other important vehicle components .•
Fewer short trips
Fuel consumption will always be relatively high on short
trips .
-Try to avoid driving short distances with a cold engine.
The engine and catalytic converter have to reach their optimal oper·
ating temperature
to reduce fuel consumption and noxious emis ­
sions effectively.
Just after starting, a cold engine in a mid-size car only achieves a fuel
economy of 6-8 m iles 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 mi les (4 km), the engine is at its proper operat ing temperature and fuel economy has reached a normal
level. So you can see that you
should avoid short trips whenever possible .
The
outside temperature is also crit ical in this regard . Your car
consumes more fue l in the winter than in the summer. •
