today 's vehicles . By "absor bing" the kinetic e ner gy over a lo ng er
p eriod of time, th e saf ety belts make the forces o n th e body mor e
"to lerable" and less likely to ca use inju ry .
Alt hou gh the se ex amp les a re based on a fr ontal col lis ion, safety bel ts
can a lso s ubstantially red uce the risk of in jur y in other ki nds of
cras hes. So , whe ther you 're o n a long tri p o r ju st go in g to th e co rner

t ics s how t hat vehi cle occupan ts properly wea rin g safety belts have a
lower risk of bei ng in jured and a muc h better cha nce of s urvivi ng an
acc ident. Properly usi ng safety belts also greatly increases the ability
of the supp lemental a irbags to do t heir job in a co llisio n. For this
reason, wea ring a safety belt is lega lly re quir ed in most countries
including muc h of th e Uni ted Stat es and Canad a.
Altho ugh your Audi is equipped with a irbags, yo u still have to wear
t he s afety bel ts provi ded. Fr ont airba gs, for ex ample, are activ ated
only in some fro nta l collisions . T he front a irbags are not activated in

& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death. Safety belts can work only when used correctly.
• Always fasten your safety belts correctly before driving off and
make sure all passengers are correctly restrained.
• For maximum protection , safety belts must always be posi ­
tioned properly on the body.
• Never strap more than one person, including small children,
into any belt.
• Never place a safety belt over a child sitting on your lap.
• Always keep feet in the footwell in front of the seat while the
vehicle is being driven.
• Never let any person ride with their feet on the instrument
panel or sticking out the window or on the seat.
• Never remove a safety belt while the vehicle is moving. Doing
so will increase your risk of being injured or killed.
• Never wear belt s twisted .
• Never wear belts over rigid or breakable objects in or on your
clothing, such as eye glasses, pens, keys, etc., as these may cause
injury .
• Never allow safety belts to become damaged by being caught
in door or seat hardware.
• Do not wear the shoulder part of the belt under your arm or
otherwise out of position.
• Several layers of heavy clothing may interfere with correct
positioning of belts and reduce the overall effectiveness of the
system .
• Always keep belt buckles free of anything that may prevent the
buckle from latching securely . .._

Automatic safety belt retractors
Every safe ty be lt is equipped with an automatic be lt retractor on the
shoulder belt . This feat ure locks t he be lt whe n the belt is pulled out
fast, d uring ha rd braking and in an accident. The belt may also lock
w hen you dr ive up or dow n a steep hill or throug h a sharp curve .
Dur ing norma l driv ing the belt lets you move freely.
Safety belt pretensioners
T he safety belts are eq uipped w ith a belt p retensioner that helps to
tighten the safety belt and remove slac k w hen the p retensioner is
activated . The f unction of the p retens ioner is monitored by a warn ing
light=>

Switchable locking feature
E very safety be lt except the one on the driver seat is equipped with a
switchab le locking feature that
must be used when the safety belt is
used to attach a child safety seat. Be sur e to read t he importa nt info r­
mation about this feature=>
page 225.
& WARNING
Improperly po sitioned safety belt s can cau se serious injury in an
accident =>
page 186, "Safety b elt position ".
• Safety belts offer optimum protection only when the seatback
is upright and belts are properly posit ioned on the body .
• Alway s make sure that the r ear seat backre st to which the
center rear safety belt is attached is se curely latched whene ver the
rear center safety belt is being u sed . If the ba ckre st is not securely
latched, the passenger will move forwa rd with the backrest during
sudden braking, in a sudden maneuve r and e specially in a crash.
• Never attach the safety belt to the buckle for another seat .
Attaching the belt to the wrong bu ckle will reduc e safety belt
effect iveness and can cause serious personal injury .
• A passenger who i s not properly restrained can be seriou sly
injured by the safety belt itself when it moves from the stronger
parts of the body into critical area s like the abdomen.

Intelligent technology
'-------------------------------------------------
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 245, "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. •

reduced.
- Let the hood
drop down and latch in place. Do not try to
push it shut;
it may fail to engage=:> &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area=>& .
& WARNING
To help avoid injury, before you check anything under the hood:
• Turn off the engine.
• Remove the ignition key.
• Apply the parking brake.
Safety first
& WARNING (continued)
• Move selector lever of automatic transmission to "P" (Park);
put manual transmission in Neutral.
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.
• Keep children away from the engine compartment.
• Never spill fluids on hot engine components. They can cause a
fire.
• Never touch the radiator fan. The auxiliary electric fan is
temperature controlled and can switch on suddenly.
• Never open the coolant reservoir cap when the engine is still
warm. The coolant system is pressurized and hot coolant could
spray out.
• Protect your face, hands and arm from steam or hot engine
coolant by placing a thick rag over the cap when you open the
coolant reservoir.
• If work on the fuel system or the electrical system is necessary:
-Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in
the engine compartment could start a fire.
- Keep an approved fire extinguisher immediately available.
• To avoid electrical shock and personal injury while the engine is
running or being started, never touch:

Have the battery checked when you take your vehicle in for service.
You are well advised to replace a battery that is older than 5 years.
With certain types of a irbag deployment, the battery is disconnected
from the vehicle e lectrical system for safety reasons=>
& in "Repair,
care and disposal of the airbags" on
page 204.
Disconnecting the battery terminals
Some vehicle functions (power window regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery terminals are connected aga in . To
prevent this, the battery should only be disconnected from the
vehicle electrical system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not dr ive your vehicle over a period of several days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains starting capability over a
longer period=>
page 243.
Take into consideration that when you unlock you r vehicle, some
convenience functions, such as the master key remote function or
power seat adjustment, may not be available. The convenience func­
tions will be available again when you turn on the ign ition and start
the engine.
W inter operation
During the w inte r months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
wh ile starting, and the headlights, rear window defogger, etc., are
used more often.
Avoid unnecessary power consumption, particularly in city traffic or
when traveling only short distances. Let your authorized Audi dealer
check the capacity of the vehicle battery before winter sets in
=> page 288. A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longer.
W Tips
If your vehicle is left standing for several weeks at extremely low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced .•
Working on the battery
Be especially careful when working on or near the
battery.
The battery is located in the luggage compartment under the
floor. Before you check anyth ing in the lu~gage compart­
ment,
read and heed all WARNINGS:=>& .
Always heed the safety warnings, when working on the vehicle
battery or the vehicle electrical system to prevent injury .
The following WARNINGS are very important when
working on the battery:
Always heed the following WARNING SYMBOLS and safety pre­
cautions when working on the battery.
Always wear eye protection.
Battery acid contains sulfuric acid. Always wear
gloves and eye protection . .,,_
