If you leave the child restraint with the tether
strap firmly installed for several days, this
could leave a mark on the upholstery on the
seat cushion and backrest in the area where
the tether strap was installed . The upholstery
would also be permanently stretched around
the tether strap . This applies especially to
leather seats .
Using tether straps on rearward-facing
child restraints
Currently, few rearward -facing child restraint
systems come with a tether. P lease read and
heed the child rest raint system manufacturer's
instruc tions care fully to de termine how to prop­
erly install the tether.
A WARNING
A child in a rearward-facing child safety seat installed on the front passenge r seat w ill be
ser ious ly injured and can be killed if the front
airbag infla tes · even w ith an Advanced A irbag
System.
- T he inflating a irbag wi ll hit the child safety
seat or infant carrier with great force and
will smash the chi ld safety seat and chi ld
against the backrest, center armrest, or
door .
- A tight tether or other strap on a rearward­
facing child restra int 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 Sys­
tem . The heav ier weight registered can
make the system wo rk as though an adult
we re o n the seat a nd deploy the Advanced
Airbag when it must be supp ressed caus ing
serious o r even fatal in jury to the c hild.
- If you must install a rearward fac ing ch ild
sa fety seat on the front passenger seat be­
cause of exceptiona l circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediate ly install
the rearward-facing child safety seat in a rear seat ing pos ition and have the airbag
Ch ild safety
system inspected by your authorized Audi
dealer .

Inte llig ent Techn olo gy
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on aga in automati­
cally when conditions have returned to normal.
St eer ing r ecomm endation
The ESC helps to stabilize the vehicle by chang ing
the steering torque .
I n vehicles with dynamic steering*, ESC also
helps to stabilize the stee ring in critical situa­
tions.
Electron ic inter axle differential lock*/
sel ective whe el t orque control *
The electronic interaxle differentia l lock (front
wheel drive) or the selective wheel torque control
(a ll whee l drive) operates when driving through
curves . The front wheel on the inside of the curve
or both wheels on the inside of the curve are
braked selectively as needed. This allows more
precise driving in curves. The applicable system
may not activate when driving in wet or snowy
conditions.
.,&. WARNING
- The ESC and its in tegrated systems canno t
overcome the laws of phys ics. This is espe­
c ially important on slippery or wet roads.
If
the systems begin acting to stabilize your
Switching on /off
vehicle, you should immediately change
your speed to match the road and traffic
conditions. Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of
a loss of vehicle control, collision and seri­
ous personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of los ing con­
trol of the vehicle increases when driving
too fast, espec ially through curves and on
slippery o r wet roads, and when driving too
close to vehicles up ahead . The ESC and its
integrated systems cannot always prevent
collisions -there is still a risk of accidents!
- Always accelerate with specia l care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
- ABS and ASR only work correct ly when all
four wheels are equipped with identical
t ires. Different tire sizes can lead to a reduc­
t ion in engine power.
- You may hear noises when the systems de­
scribed are working.

Intelligent Technology
Braking
What affects braking efficiency?
New brake pads
During the firs t 25 0 miles (400 km), new b rake
pads do not possess their full braking effect , they
have to be "broken i n" first ¢& . You can com­
pensate for this slight ly reduced braking power
by push ing harder on the brake pedal. Avoid
heavy braking loads during the break-in period .
Operating conditions and driving habits
The brakes on today's automobiles a re still sub ­
ject to wear, depend ing largely on ope rating con ­
ditions and driving habits¢& . On vehicles that
are either dr iven most ly in stop-and-go city traf­
f ic or are driven hard, the brake pads should be
checked by you r authorized Aud i dea ler more of­
ten than spec ified in the
Warranty & Mainte­
nance booklet .
Failu re to have your brake pads
i n spected c an resu lt in reduced bra ke pe rform­
ance.
O n steep slopes, you sho uld use the braking ef ­
fect of the eng ine . This way, you prevent unnec­
es sary wear on t he b rake system. If yo u m ust use
your b rake s, d o not hold the brakes down cont in­
uously. Pum p th e b rakes at intervals.
Operating noise
Noises may occur when brak ing depend ing on the
speed, b raking force and outs ide cond it ions such
as tempe ra tu re and humidi ty.
Effect of water and road salt
In certain s ituations, for example after driving
through water, in heavy ra in, afte r ove rnig ht con ­
densat ion or after washing your car, the b raking
effect can be reduced by mo isture or ice on the
b rake rotors and b rake pads . T he brakes must be
d ried first w ith a few careful b rake a pplica tions.
At highe r speeds and with t he windsh ield wipers
tur ned on, the br ake pads press aga inst the brake
rotors for a sho rt amoun t of time. This occur s at
regular intervals w it h out t he dr iver noticing and
p rov ides for better bra ke response time under
wet conditions.
180
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and t he b rakes are not used . Likewise, yo u clean
off accum ulated salt coating from brake discs
and pads with a few caut ious app lications of the
brake ¢& .
Corrosi on
There may be a tendency fo r dirt to build up on
the b rake pads and corrosion to form on the discs
i f the car is not driven regu larly or only for short
trips with little use of the brakes .
If the bra kes are not used frequent ly, or if corro­
s ion has formed on the discs, it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed ¢ &.
Faults in th e brake system
If you shou ld notice a sudden increase in brake
pedal travel , then one of t he two brake circu its
may have failed¢& .
Low brake fluid level
Malfu nctions can occu r in the brake system if the
br ake fluid level is too low . The brake fluid leve l
is mo nitored electronica lly .
Brake booster
The bra ke booster i ncreases the press ure t hat
yo u ge nera te with the brake ped al.
It works only
whe n the eng ine is ru nning .¢ &
Brake lining wear status
Brake lining wea r may be c hecked by visua l in­
spection o f the condition of the brake pads
t hr ough t he openings in t he wheel. If necessary,
t h e wheel m ay be removed fo r thi s inspe ction
¢ page 240, Replacing wheel s.
_& WARNING
- New brake pads don't have the be st sto p­
ping power and m ust be " broken-in" du ring
the initial 250 miles (400 kilometers). You
can compensate for this by p ressing the
brake pedal more firmly. This also app lies
later w hen new pads are installed.

of the battery is extended.
Basically, energy management consists of
bat ­
t e ry di agno sis, idl ing curr ent mana gement
and
dy namic en ergy management .
Battery diagnosis
Battery diagnosis continuous ly determines the
state of the batte ry . Sensors dete rm ine battery
voltage, batte ry current and battery tempera­
ture . This determ ines the current state of charge
and the power of the battery.
Idling current management
Idling current management reduces energy con­
sumpt io n while the veh icle is stand ing . With the
i gn it ion sw itched off, it controls the energy sup­
p ly to the various ele ctrical components . Data
from battery diagnosis is considered.
D epending on the battery's state of charge, ind i­
vid ual consume rs a re gradually turned off to p re­
vent excessive discharge of the battery and thus
maintain starting capability.
Dynam ic energy management
While the vehicle is being driven, dynamic energy
management dist ributes the ene rgy generated
accord ing to the needs of the individual compo ­
nents . It regulates cons umption, so that mo re
e lectrica l energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.
@ Tips
- But even energy management cannot neg­
ate the limits of physics. Consider that the power and life of a battery are limited.
- If starting ability is threatened, the indica­
tor light

What you should know
The highest priority is given to maintaining start­
ing capability.
The ba tte ry is severely taxed in short -d istance
driving, in city traffic and d uring the co ld time of
year. Abundant electrical energy is requ ired, but
Intellig ent Technology
on ly a little is generated . It is a lso 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 precisely these situations that you will no ­
tice energy management actively regulating the distribution of energy .
Vehicle stands for an extended period
If you do no t drive your vehicle ove r a period of
severa l days o r weeks, electrical components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca ­
pability over a longer period. Some of the con­
venience functions may not operate, such as the interior lights or the power seat adjustment. The
convenience functions will be ava ilable aga in
when you switch on the ignition and start the en­
gine.
With the engine turned off
If you listen to the rad io, for example, with the
engine turned off or use other MMI funct ions,
the battery is being d ischarged .
If starting capab ility is jeopardized due to energy
consumption, a message appears in the MMI dis­
play . The message ind icates that the system will
be switched off automat ica lly in a moment . If
you w ish to continue using the funct ions, you
have to sta rt the eng ine.
With the engine running
Although e lectr ical energy is generated when the
vehicle is being driven, the battery can become
discharged. This happens mostly when little en­
ergy is being generated and a great dea l con­
s u med and the batte ry's state of charge is not
optimal.

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
F ue l economy, environmenta l impact, and we ar
on your engine, brakes and tires la rgely depend
on three factors :
- you r persona l dr iving sty le
- operating conditions
- technical lim itations
If you anticipate what you need to do next and
drive economically, you can eas ily cut your fue l
consumption by
10-15 percen t. This section will
g ive you some tips on how you can help the envi ­
ronment and yo ur pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not cor re­
spond to your actual consumption on the
road, which will va ry depending upon vehicle
load and speed, road and wea ther condi tions,
t rip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
" Avoid unnecessary accelerating a nd braking .
Veh icles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next , you will need to brake less and, thus, accel­
e rate less . let the vehicle coast wheneve r possi ­
b le -fo r example when yo u see that the next traf­
fic light is red .
Driving and the envir onment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car 's maximum
speed.
Acce lerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­
ment.
Fuel consumption, exhaust emissions and engine
noise increase disproport ionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumption will be reduced by
one half. Never drive faster than the posted
speed limit and weather cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run at idle.
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at railroad cross ings, or at traff ic lights that have long waits
on red . Turning the engine off for just
30 -40 sec ­
onds saves more f uel than is burned starting the
. . engine again.
It takes a long time for the eng ine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially h igh when
the engine is warming up . So yo u should dr ive
away as soon as you start the eng ine and avoid
runn ing at high rpms w hile the engine is st ill
warming up .
(D Note
Do not leave eng ine idling unattended after
s tart ing. If wa rning lights sho uld come on to
i ndicate improper operation, they would go
unheeded . Extended idling also prod uces
heat, which could resu lt in overheating or
other damage to the vehicle or other proper­
ty.
187

Driving and th e en vironm ent
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
.,. Have your vehicle serviced at regular intervals.
By having your vehicle regu larly serviced by an
author ized Audi dealer he lps to ensure that it
runs properly and econom ically . The condition of
your veh icle not only affects its safety and ability
to hold its value, it also affects
fu el consump­
tion .
C he ck your oil e ach t ime you fill you r ta nk .
The amount of oil used is re lated to engine load
and speed.
It is normal for the oil consumpt ion of a new en­
g ine to reach its lowest val ue afte r a certa in mile­
age has been driven .
You must d rive you r vehicle about 3 ,000 miles
(5,000 k ilome ters) before you can p roperly as ­
sess o il cons umption .
This a lso applies to fuel consumption and engine
outpu t.
(D Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in you r Warranty
& Maintenance book ­
l et . La ck of p roper main tenance as well as
i mproper use of the vehicle will impa ir the
f u nct ion of the emission control system and
could lead to damage.
- Do not al ter or remove any component of
the Emission Control System unless ap­ proved by the manufacturer.
- Do not a lter or remove any device, such as
heat shie lds, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other i mportant vehicle components.

· Fewer short trips
Fuel consumption will always be relatively high
on short trips .
.,. Try to avoid driving short distances with a cold
eng ine .
T he eng ine and catalytic converter have to reac h
their opt imal
operating temper atu re to reduce
fuel consumpt ion and noxious emiss ions effec­
tively .
Just after start ing, a cold engine in a mid-size car
on ly achieves a fuel economy of 6-8 miles 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 m iles (4 km), the engine is
at its proper operating temperatu re and fuel
economy has reached a no rma l level. So you can
see that you should avoid sho rt tr ips wheneve r
possible .
The
out sid e temperatur e is also cr it ica l in th is re­
gard. Your car cons umes more fue l in the winter
than in the summer.

Be s ure trai ler s afety chains are p ro p erly conne ct­
ed from the trailer to the hitc h on the vehicle .
L eave enough slack in the chains to permit turn­
ing corners . When you install safety cha ins, make
sure they w ill not drag on the road when yo u are
driving.
The chains s hou ld cross under the t railer tongue
to p revent it from dropp ing in case of separat ion
from t he hitc h.
Driving instructions
Driving with a trailer always requires extra core
and consideration.
To ob tain the best possible handling of vehicle
and trailer, please note the fo llowing :
.,. Do no t tow a lo ad ed t railer w hen yo ur car i tse lf
i s not lo ad ed.
.,. Be especia lly caref ul when passing ot he r
vehicles .
.,. Observe speed limits.
.,. Do not d rive at the maximum permissible
speed .
.,. Always apply brakes early .
.,. Moni to r th e temperature gauge .
Weight distribution
T owing a loaded trailer w ith an empty car res ults
in a high ly unstable distribution of weight . If this
cannot be avo ided, drive at very low speeds o nly
to avoid the risk of losing steering control.
Trailer mode
A "ba lanced" rig is easier to opera te and co ntrol.
This means that the tow vehicle sho uld be loaded
to the extent possib le and permissib le, w hile
keeping the trailer as light as possible under the
cir cumstances . Wheneve r poss ib le, transfer
some cargo to the luggage compartment of the
tow ve hicle while observing tongue load require­
ments and vehicle loa ding consi de rations .
Speed
The higher the speed, the mo re diff icult it be­
comes for the driver to control the r ig. Do not
drive at t he max imum permissib le speed. Reduce
you r sp eed even more if load, weathe r or wind
cond it ions are u nfavo rab le -pa rticularly when
go ing down hill.
Reduce vehicle speed
immediately if the trailer
shows the slightes t sign of sway ing .
Do not try
to stop the swaying by accelerating .
Observe speed limits . In some a reas, speeds fo r
vehicles towing trailers are lower tha n for regular
vehicles .
Always apply bra kes early . When d riving down­
hill, shift into a lower gear to use the e ngine
braki ng effect to slow the vehicle . Use of the
brakes alone can cause them to overhea t and fa il.
Coolant temperature
The coo lant tempe rature gauge c:> page 10 m ust
be obse rved caref ully. If the needle moves close
to the upper end of the scale, reduce speed im­
me diate ly and/or t urn
off th e a ir cond it io ne r .
If the coolant temperat ure warning light . in
t h e instr ument cluster starts flashing, pull
off
the road, stop and let the engine idle for about
two m inu tes to pre vent heat build -u p .
