vertib le locking retractor is now act ivated.
Child Sa fet y 139
.,. Make sure that the red release button is fac ­
ing away from the child restraint so that it
can be unbuckled qui ck ly.
.,. 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 . S cm).
A WARNING
Using the wrong child res traint o r an im­
properly installed chi ld restraint can cause
serious personal injury or death in a crash.
- Always ma ke sure that the safety belt re-
tractor is loc ked when insta lling a child
safety seat . An unlocked safety belt re­
tractor cannot hold the child safety seat in place during norma l driving or in a
crash.
- Always buckle the child safety seat firmly
in place even if a chi ld is not sitting in it.
A loose child safety seat can fly around during a sudden stop or in a crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright pos ition. Otherw ise, the seat­
back with the ch ild safety seat attached
to it could fly forward in the event of an accident or other emergency situation .

142 Intelligent technology
switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
l!l . Be sure to
switch ESC on again when you no longer need
less traction.
Anti -toc k brak ing system (ABS)
ABS prevents the wheels from lock ing up
when braking . The vehicle can still be steered
even during hard brak ing . Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal ind icates that
the system is he lp ing you to brake the vehicle .
Brake assist sy stem
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presse s the brake pedal quickly in emer­
gency si tuations. You must press and hold the
brake peda l until the situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to the road conditions . This makes it easier to
start, accelerate and drive up hills.
E lectronic differential lock (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL a utomatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL will switch on aga in au­
tomatically when conditions have returned to normal.
A WARNING
- ESC, ABS, ASR and ED L can not ove rcome
t h e laws of phy sics. This is espe cial ly im ­
por tant on slip pery or wet ro ads .
If th e
sys tems begin a ct in g to stab ilize your ve­
hicle, you shou ld imme diately change
yo ur speed to match the road and traffic
condit ions. Do not let the inc reased safe­
ty provided by these systems tempt you to take risks. Do
ing so w ill increase the
risk of a loss of veh icle control, co llision
and serious pe rsonal injuries .
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of t he vehicle increases when
driving too fast, espec ially through
curves and on slippe ry or wet roads, and
wh en dr iv ing too clos e to vehicl es u p
ahead. ESC, A BS, the brake ass ist sys­
tem, ED L and ASR cannot p reven t coll i­
si ons .
- Always acceler ate wi th sp ecial c are on
even, smoo th s urfaces such as those th at
are wet or covered with ice and snow .
The drive wheels can spin even with
these assistance systems that cannot al­ ways he lp to reduce the risk of loss of ve­
h icle co ntrol.
(D Tips
- ABS an d ASR only wo rk correct ly when
all four whee ls are equipped with identi­
cal tires . D ifferent tire si zes can lead to a
reduction in engine powe r.
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator light Ii) or II (USA
mode ls)/ Ei] (Canada models) appears,
there may be a malfunction

A WARNING
Only switch ESC sport mode on when your
driving abilities and the traffic s ituation
permit . Please note that the dr iv ing
w heels can spin and the vehicle can break
away in ESC sport mode, especia lly when
t he road is slippery.
(D Tips
If the re a re faults in the rear spo iler sys­
tem or in Audi magnet ic r ide, it may not be
possible to act ivate ESC sport mode o r
normal mode may act ivate aga in a utoma t­
ically.
Rear spoiler
Appl ies to vehicles: with retractable rear spoiler
The rear spoiler improves vehicle handling
and enhances driver control.
Fig. 122 Switch for rear spo ile r
Intelligen t technolog y 143
The rear spoi ler deploys and retracts . Spoiler
operation can be set for automatic or man ual
operation.
Aut omatic mode (normal ope ration )
- Automatic deployment : At a speed of about
75 mph (120 km/h), the rea r spo ile r deploys
automatically .
- Au tomatic retraction: When speed drops be­
low about SO mph (80 km/h), the rear spoil­
er retracts a utomatica lly.
Manual mode
- Man ual deployment : T app ing br iefly on the
sw itch
¢ fig . 122 deploys the rear spoiler.
- Manual retraction : At speeds up to about
10 mph (20 km/h), retract the rear spoiler
by pressing and holding the sw itch
¢ fig. 122. At speeds between 10 mph (20
km/h) and 75 mph (120 km/h), retract the
rear spoi ler by tapping on the switch
¢ fig. 122 .
A WARNING
-
Driving at higher speeds without the rear
spoiler deployed can impair handling char­
acter istics, making the vehicle harder to
control.
- Always make su re that the spo ile r is de­
ployed when driving at speeds over
85 mph (140 km/h) . If th e rear spoil er
warn ing/ indicator light in the inst ru­
men t cluster comes on, the rear spoiler
may not have deployed.
- Never d rive a t speeds higher than
85 mph (140 km/h) i f th e spoiler is not
deployed . Have the spoiler inspected as
soon as possible by an authorized Audi
dea ler or qualified workshop.
- A lways obey speed limits and other traf­
fic laws .
A WARNING
Improper operation of the rear spoi ler can
cause crushing injuries .
- Always make sure that nobody, especially
children, is in the way when the rear
spoiler is dep loyed or retracted.

A WARNING
-You should perform brak ing maneuvers
for the purpose of cleaning the brake
system only if road cond it ions permit .
Other road users must not be put at r isk -
yo u may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transm iss ion into a lowe r
gear or lowe r driving range. Do not ride
the brakes or hold the pedal down too
long or too often . This cou ld cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the b rakes" by resting your
foot on the pedal when yo u do not intend
to brake . Th is may cause the brakes to
overheat, premature wear and increased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing throug h wa­
ter, driving in heavy rai n or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, lini ngs,
discs and d rums. Carefully apply brakes
f or a test . B rakes wi ll dry and ice coat­
ings wi ll be cleaned
off after a few ca re ­
ful brake applications.
- Driv ing for an ex tended pe riod of time on
salt -covered roa ds without using your
brakes can also affect braking efficiency.
Clean
off accumulated salt coating from
brake discs and pads with a few cautious
brake applicat ions.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed . Otherwise the brake system could
overheat reducing the eff ectiveness of
the ent ire brake system.
- Failure of one bra ke c ircuit will impair
the brak ing capability resulting in an in­
cr eased stopp ing distan ce. Avoid dr iv ing
the ve hicle and have it towed to the near­
est Aud i dea le r or q ualified workshop .
- Never le t the vehicle ro ll to a stop w ith
the engine shu t off.
Int ellig ent technolog y 145
-If the brake booster is not working, the
brake peda l must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Electro-mechanical
power assist
The ele ctro-mechanical power assist helps
the driver when steering .
The degree of power assist is electronically
matched to veh icle speed.
The powe r steering system assists the driver
so that he can steer the vehicle with reduced
physical effort.
Power steer ing will not work if the engine is
off . As a result, the steering wheel will be hard
to turn .
A WARNING
If the system develops a problem, you
must seek qualified professiona l assis­
tance.
(D Note
-
If there is an electronic malfunction, ser­
votronic
will still function like a conven­
tiona l powe r steering system, providing a
constant steering support force tha t is no
l onger proportionate to the vehicle speed.
This is most noticeable when t urning the
steering wheel at low speeds (for example
when parking), - more effort w ill be re­
quired than usual.
- Be aware of the different than usual
steering response and adjust your steer­
ing force accordingly.
- Have the problem checked and set right
by an authori zed Aud i dea ler as soon as
possible.
- If a steering malfunction occurs, th is is
signa led w ith the
ls4 or .• indicator
lights and a warn ing tone, see. •

152 Driving and en vironm ent
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage .
"'Try and keep well below your car 's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment. F ue l consumption, exhaust emissions and en ­
gine no ise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will be reduced by one half. Never dr ive faster
than the posted speed limit and weather con­
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
"'Shut the engine off when you are not driv ing
the vehicle .
"'Do not warm up the veh icle by letting the
engine run at idle .
It makes sense to shut
off the e ngine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings , or at traff ic lights that have
l ong wa its on red. Turning the engine
off fo r
just
30-40 seconds saves more fue l than is
burned s tarting the eng ine again .
It takes a long time for the engine to warm up
fully when it is running at idle . Howeve r, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high RPMs while the engine
is sti ll warming up.
([) Note
Do not leave engine idling unattended af ­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over- heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
"' Have your ve hicle serviced at reg ular in ter -
vals.
By having your veh icle regu la rly serviced by an
Audi dealer he lps to ensure that it runs p rop­
erly and economically. The condition of your
vehicle not only affects its sa fety and ability to
hold its val ue, it also affects
fuel con sum p­
tion .
Check your oil e ach time you fill your t ank .
The amount of o il 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 certa in
mileage has been driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometres) before you can properly
assess oil consumpt ion.
This also app lies to fue l cons umption and en­
gine output.
(D Note
- Have your vehicle maintained proper ly
and in accordance with the service rec ­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss ion contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control Sys tem unless ap­
proved by the manufacturer.
- Do not alte r or remove any device, such
a s hea t sh ie lds, switches, ig nition w ires,
valves, which are designed to protec t
your vehicle's Emission Control System
and other impo rtant vehicle compo­
nents .

washer.
- To reduce the risk of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the
surface, do not use polishing agents or hard wax.
- Never use car wash cycles that apply
protective wax.
It can destroy the
matte fi nish effect.
- Do not place any stickers o r magnet ic
signs on vehicle parts painted w ith
matte fin ish paint. The paint cou ld be
damaged when the stickers o r magnets
