Many types and models of child restra ints
have been ava ilable over the years, new mod
els are introduced regular ly incorporating new
and improved designs a nd older models are
taken out of production . Child rest raints are
not standardi zed. Ch ild restra ints of the same
type typi cally have differen t weights and s izes
and d ifferent "footprints", the size and shape
of the bottom of the child restraint that sits
on the seat, when they are installed on a vehi
cle seat. These differences make it virtually imposs ible to certify compliance w ith the re
qu irements for advanced a irbags w ith each
and every child restraint that has ever been
sold in the past or will be sold over the course
of the useful life of you r vehicle .
For this reason, the United States National
Highway Traffic Safety Admin istration has
published a list of specific type, makes a nd
models of child rest raints that must be used
to certify compliance of the Advanced Airbag
System in yo ur vehicle with the suppress ion
requirements of Federal Motor Vehicle Safety

A WARNING
To reduce the risk of serious inju ry, ma ke
sure that the
PASSENGER AIR BAG OFF
l ight comes on and stays on whenever a
chi ld restraint is installed on the front pas
senger seat and the ignition is switched
on.
- Take the chi ld restraint off the front pas
senger seat and install it properly at one
of the rear seat positions if the

Anti -slip regulation (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Electronic differential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the d rive power to the other wheels.
This f unct ion is not availab le at h igher speeds.
In extreme cases, EDL automat ically switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on aga in au
tomatically when conditions have returned to norma l.
St eering recommendat ion
The ESC helps to stabilize the vehicle by
cha nging the steering to rque.
In vehicles with dynam ic steering*, ESC also
helps to stabilize the steering in critical s itua
tions .
Select ive w heel to rque control
Selective wheel torque control is used when
driving on curves . The front wheel on the in
side of the curve or both wheels on the inside
of the curve are braked selectively as needed.
This a llows more prec ise driving in curves. The
applicable system may not activate when d riv
ing i n wet or snowy conditions.
.&_ WARNING
- T he ESC and its integrated systems can
not overcome the limits posed by natural physical laws
. This is especially impor
tant on slippery or wet roads. If the sys tems beg in acting to stabilize your vehi
cle, you should immediately change your
speed to match the road and traffic con
d itions . Do not let the increased safety
p rovided by these systems tempt you to
take risks. Do ing so will increase the ri sk
of a loss of veh icle cont ro l, collision and
serio us personal inj uries.
- Always adapt your speed to road, traffic
and weather conditions . The risk of los
ing control of the vehicle increases when
driving too fast , especially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead . The ESC and its integrated sys
tems cannot a lways prevent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth su rfaces such as those that
are wet or covered with ice and snow .
The drive wheels can spin even w ith
these assistance systems that c annot al
ways he lp to red uce the risk of loss of ve
h icle control.
(D Tips
- ABS and ASR only wo rk correctly when
all four wheels are equipped wi th iden ti
cal tires. D ifferen t tire sizes can lead to a
reduction in engine power.
- Yo u may hear noises when the systems

206 Driving and en vir onm ent
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre
spond to your actual consumption on the
road, which will vary depending upon vehi
cle load and speed, road and weather con
ditions, tr ip length, etc .
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac
celerating.
• Avoid unnecessary accelerating and braking.
Vehicles use the mo st fuel when they are ac
celerating . If you anticipate what is go ing to
happen next, you will need to brake less and,
thus , accelerate less. Let the vehicle coast
wheneve r poss ible -for example when you see
that the next traffic l ight is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
• Try and keep well below your car 's max imum
speed .
Accelerating gently reduces fuel consump
tion, engine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en
g ine no ise increase d isproportionately at high
speeds. If you dr ive at approximately three
quarters of top speed, fue l consumption will
be reduced by one half. Neve r dr ive faste r
than the posted speed limit and wea ther 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 dr iv ing
the vehicle. •
Do not warm up the vehicle by letting the
engine run at id le .
T he id ling phase is automatically red uced for
vehicles with the Start -Stop -System . It is effi
cient to switch off the engine in vehicles with
out the Start-Stop -System when stopp ed at
railroad crossings and long red lights. Tu rning
the engine off for jus t 30-40 seconds saves
more fuel than is burned by starting the en-
. . gme again .
It takes a long time for the eng ine to warm up
fully when i t is running at idle. However, wear
and noxiou s emissions are espec ially high
when the eng ine is warm ing up . So you should
drive away as soon as you start the engine and
avo id running at high rpms while the engine is
still warming up.
W Note
Do not leave engine idling unattended af
ter start ing . If wa rning lights should come
on to indicate improper operation, they
wo uld go unheeded . Ex tended idling also
produces heat, wh ich could result in ove r
heating or other damage to the ve hicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
• Have your veh icle serviced at reg ular in ter -
vals .
By having your ve hicle regu la rly se rviced by an
Audi dealer he lps to ensu re tha t it runs p rop
erly and economically . The condition of your
vehicle not only affects its safety and ability to
ho ld its va lue, it also affects
fuel con sump
tion .
Check your oil e ach time you
fill y our tank.
The amount of o il used is re lated 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 bee n driven . ..,.
208 Trailer towing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen
ger transportation .
If you plan to tow a trailer, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra
tion from the driver.
For this reason, always follow the operating
and driving instructions provided and use
common sense.
@ Note
If you are going to tow a trai ler, you must
activate the trailer operation mode
c:::> page 208, Operating instructions.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita ble for your vehicle and trailer and must be
mounted securely on the vehicle's chassis at a
technically sound location . Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the cor rect
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys
tems . From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trai ler hitch ball mount. This prevents the
hitch from causing damage should your vehi
cle be struck from behind
c:::> A.
Trailer brakes
If your trailer is equipped with a brakin g sys
tem, check to be sure that it conforms to all
regulations.
T he trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system .
Safety chains
Always use safety chains between your veh icle
and the trailer.
Trailer lights
Trailer lights must meet all regulations. Be
sure to check with your Audi dealer for correct
wiring, switches and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors. It is important
that you
always have clear v is ion to the rear .
A WARNING
--
After removing the trailer hitch, do not
store it in your vehicle . In case of sudden
braking, the hitch could fly forward and in
jure you or your passengers.
Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trailer is held securely
in place to prevent it from shift ing forward,
backward or sideways.
Never allow a passenger to ride in a trailer
c:::> A in Driving instructions on page 210.
Engine cooling system
Towing a trailer makes the engine work hard
er . It is important that the cooling system 's
performance is up to the additional load.
210 Trailer towing
A lways apply brakes early. When driving
downhill, shift into a lower gear to use the en
g ine braking effect to slow the vehicle . Use of
the brakes alone can cause them to overheat
and fail.
Air su spen sion *
When driving with a trai ler, activate the trailer
mode of the air suspension. Switch the air
suspension trailer mode on when you are tow
ing a trailer. This will limit the regulation by
the air suspens ion while driving. Select in the
MMI:
! CARI function button> (C ar)* sys te m s
control button > Vehicl e se tting s> Air s usp .:
t o wing > On .
Coolant t emperatur e
The coolant temperature gauge¢ page 11
must be observed carefully. The coolant tem
perature can increase if you drive on long in
clines in a low gear at high engine speeds. Re
duce your speed immed iate ly if the LEDs in
the top pa rt of the display turn on.
For more information about indicator lights,
refer to. ¢ page 16 .
A WARNING
Anyone not properly restrained in a mov
ing veh icle is at a much greater risk in an
accident. Never let anyone r ide in your car
who is not prope rly wearing the restraints
provided by Audi .
Trailer towing tips
Important to know
Your vehicle handles differently when tow ing
-
a trailer because of the addit ional weight and
d ifferent weight dist ribution. Safety, perform
ance and economy w ill greatly depend on how
carefu lly you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turn ing, stopp ing and back ing up in an area
away from traffic. Keep practicing until you
have become comp letely familiar with the way your vehicle
-trailer combination behaves and
responds .
Backi ng up is diffic ult and requi res p ractice.
Backing up w ith a trailer generally req uires
steering action opposite to that when backing
up your vehicle without a trailer.
Maintai n a greater d ista nce between yo ur ve
hicle and the one in fron t of yo u. You w ill need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius.
When passing, remember that you cannot ac ce le rate as fast as you norma lly would be
ca use of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your trailer before chang
ing lanes again.
Avoid jerky starts, sharp tu rns o r rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re
quire more frequent maintenance due to
the extra load ¢
page 294.
Parking on a slope
Do not park on a slope with a trailer. If it can
not be avoided, do so only after doing the fol
lowing:
When parking:
.,. App ly the foot brake .
.,. Have someone place choc ks unde r both the
vehicle and the trailer wheels.
.,. With chocks in place, slowly release the
brakes unt il the whee l chocks absorb the
load .
.,. Turn the whee ls towards the curb.
.,. Apply the parking brake.
.,. Select the P selector lever posit ion.
When re sta rting after p ark in g :
.,. App ly the foot brake .
.,. Start the engine.

"' rl
-Always dispose of used engine oil proper
ly. Do not dump it on garden soil, wood
ed areas, into open streams or down
sewage drains.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station.
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro
tects the engine from freezing in the winter.
The cooling system is sealed and generally re
quires little attention .
The cooling system has been filled at the fac
tory with a permanent coolant which does not
need to be changed . The coolant consists of a
mixture of specially conditioned water and the
manufacturer 's glycol-based coolant addi-
tive G13 antifreeze with anticorrosion addi
tives (50% for USA models; 60% for Canadian
models) . This mixture both assures the neces
sary frost protection and protects metal com
ponents in the engine's cooling system from
corrosion and scaling.
It also raises the boil
ing point of the coolant.
Do not reduce the concentration of the cool
ant in the summer by adding plain water.
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main
tain antifreeze protection and cooling efficien
cy .
If the coolant frost protection is too low,
the coolant could freeze and damage the vehi
cle heating and engine cooling system.
For year -round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- -40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of wa
ter and coolant additive. Mixing the coolant
additive with distill ed water is recommended .
Checking and filling 231
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ~&.
in Working in the engine
compartment on page 225.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli
mate conditions. This is especially impor
tant if you live in a region where the win
ter is extremely cold. If necessary, in
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad
ditive G12++ or G13 (check the label)
for your vehicle. This coolant additive is
available at authorized Audi dealers.
Other types of antifreeze can signifi
cantly reduce corrosion protection. The
resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

,.. Read the brake fluid level from the brake
fluid reservoir¢
fig . 197, ¢ page 22 7,
fig. 193.
The brake flu id level must be be
tween the "MIN" and "MAX" markings.
The location of the brake flu id reservoir can be
seen in the engine compartment illust rat ion
¢ page 227.
The fluid level may drop
slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm.
If the brake fluid level falls
considerably be
low the "MIN" mark, the brake warning/indi
cator light . (U.S. models)/ . (Canadian
models) will come on¢
page 15. Do not con
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized A udi dealer or other quali
fied facility and the cause corrected.
If the
brake fluid level is too low, the brake warning/
indicator light will illuminate. Contact an au
thorized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi
enced technician .
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also decrease conside rably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
every two years . Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to reach, therefore, we recommend that you
have the brake fluid changed by your author
ized
Audi dealer. Your dealer has the correct
tools, the right brake fluid and the know-how
to do this for you.
A WARNING
- Brake fluid is poisonous . It must be stor
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap
propriate brake fluid. Observe these pre
cautions:
- Use only brake fluid that meets SA E
specification
J 1703 and conforms to
Federal Motor Vehicle Standard 116.
Always check with your authorized Audi
dealer to make sure you are using the
correct brake fluid. The correct type of
brake f luid is also indicated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
long. This can seriously affect the effi
c ie ncy of the brakes as well as your
safety. This could resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .
