13 2 Safety belts
Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety be lts are nec ­
essary, how they work and how to adjust and
wear them correctly .
.. Read a ll the information that fo llows and
heed all of the instruct ions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of ser ious
personal in jury and death .
- Safety belts are the sing le most effective
means avai lab le to reduce the risk of se­
r ious injury and dea th in a utomob ile acci­
dents. For your protection and that of
yo ur passenge rs, always co rrectly wear
safety belts when the vehicle is moving.
- P regnant women, injured, or physically
im paired perso ns mu st also use safety
bel ts. Lik e all veh icle occup ants, they are
more like ly to be ser iously injured if they
do not wea r safety be lts . The best way to
protect a fetus is to protect the mother -
throughout the entire pregnancy.
Number of seats
Your Audi has a total of four seating positions: two in the front and two in the rear. Each seat­
ing position has a safety belt .
A WARNING
Not wearing safety belts or weari ng them
improp erly increases th e risk of ser ious
pe rsonal i njury and dea th.
- N ever st rap more than one pe rson, in­
cl uding small ch ild ren, into any belt.
It is
e speci ally dange rous to pla ce a safety
belt over a child s itting on yo ur lap.
- N ever le t mo re people ride in the ve hicl e
than there are s afe ty be lts avail able. -
Be s ure everyone riding in the vehicle is
properly restrained w ith a separate safe ­
ty belt or child restra int.
Safety belt warning light
Your vehicle hos o warning system for the
driver and (on USA models only) front seat
passenger to remind you about the impor­
tance of buckling-up .
Fi g. 139 Safety belt warni ng lig ht in the instrument

Before driving off, always :
.. Fasten you r safety belt and make sure you
are wearing it properly .
.. Make s ure that yo ur passengers a lso buck le
up and properly wear their safety be lts.
.. Protect your children w ith a child rest raint
system approp riate fo r the size and age of
t he children.
The . war ning light in the instrument cluster
lights up when the ignit ion is switched on as a
rem inder to faste n the safety belts. In addi­
t ion, you will hea r a warning tone for a certa in
per iod of t ime.
Fasten your safety b elt now and make sure
that your pas sengers also properly put on
their safety belts.

190 Driving and en vironm ent
(0 Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could 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 vehicle serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
author ized Audi dealer he lps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ab il ity to hold its value, it also affects
fu el
con sump tion .
C heck your oil each time you fill your tank.
The amount of oil used is related to engine
l oad and speed.
I t is normal for the oil consumption o f a new
engine to reach its lowest val ue after a certain
mileage has been driven.
You mus t drive yo ur vehicle abo ut 3,000 miles
(5,000 kilometers) be fo re yo u can properly
assess oi l consumption.
This a lso applies to fuel consumption and en­
g ine output.
(]) Note
-Have yo ur vehicle maintai ned properly
and in accordance with the service re c­
ommendations in your War ran ty
& Mai n­
tenance bookle t. Lack of proper mainte ­
nance as well as imp roper use of the
ve­
hicle will 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 ap­
proved by the manufacturer .
- Do not alter or
remove any device, such
as heat shie lds, switches, ignition w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances w ith a
cold engine.
The engine and cata lytic converter have to
reach their opt imal
oper ating temperature to
reduce fuel consumpt ion and nox ious em is­
s ions effectively.
Just after starting, a co ld engine in a mid-size
car on ly 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 miles (4 km),
the engine is at its prope r operating tempera­
tu re and fuel economy has reached a normal
level. So you can see that yo u should avo id
short trips whenever poss ible.
T he
outside temperatur e is also cr it ical in t his
regard. Your car consumes more fue l in the
winter tha n in the s umme r.

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb­
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys­
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
trai le r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from be hind
¢ &. .
Trailer brakes
If yo ur tra iler is equ ipped w it h a braking sys­
tem, check to be su re that it conforms to a ll
r eg ulat io ns.
Trailer towin g 191
The trailer hyd ra ulic bra ke system must not be
direct ly connected to the vehicle's hydraulic
brake system
¢ &. .
Safety chains
Alw ays use s afety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r lights m ust meet all reg ulations . Be
su re to check w ith your authorized Audi dealer
fo r c orrec t w iri ng, sw itches, and relays.
Mirrors
If you a re unable to see the traffic behind you
u sing the regula r outside m irrors, then you
must insta ll ext ended mir ro rs. It is important
t h at you
always have clea r vis io n to the rear .
.8, WARNING
- If a trailer has elec trica l br ake s plea se
no te th at t hese bra kes are not activat ed
by the fa ctory -fit ted control unit -risk of
accident!
- After removing the t railer hi tch, do no t
s to re it in yo ur vehicle . In case of sudden
brak ing, the hitch could fly fo rward and
in ju re you or yo ur passenge rs .
Operating instructions
Maximum traile r we ight
-
A trai ler for your vehicle is limited to a typical
class 1 or class 2 tra iler.
Trailer load distribution
Be sure the lo ad in the traile r is h eld secure ly
i n p lace to p reven t it from shifting fo rward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢ &. in Driving instru ctions on page 19 2.
Engine cooling system

192 Trailer towing
Tire pre ss ure
When towing a trai le r, inflate the t ires of your
vehicle to the co ld tire pressure listed under
"Full load" on the label located on the driver 's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac ­
turers' specifications.
Light s
The headlight settings should be checked with
the trailer attached before dr iving off. Check
to make sure both vehicle and tra iler lights
are working properly.
Saf ety chains
Be sure tra iler sa fe ty cha ins a re p roperly con­
nected from the trailer to the hitch on the ve ­
hicle. Leave eno ugh slack in the chains to per ­
mit turning corners. When you install safety
cha ins, make sure they w ill not drag on the
road when you are driving.
The chains shou ld cross under the trai ler
tongue to prevent it from dropping in case of
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obtain the best possible handling o f vehicle
and trai ler, p lease note the following:
.,. Do not tow a loaded tra iler whe n your car it ­
self is no t loaded .
.,. Be especia lly careful when passing other
vehicles .
.,. Observe speed limits .
.,. Do not drive at the maximum permissible
speed.
.,. Always apply brakes early .
.,. Monitor the temperature gauge.
Weigh t di stribution
Towing a loaded trai ler with an empty car re­
sults in a highly unstable distribution of
weight . If this cannot be avo ided, drive at very
low speeds only to avoid the risk of losing
steer ing control. A "ba
lanced' ' rig is easier to operate and con­
trol. This means that the tow vehicle should be loaded to the extent possible and permissi­
ble, while keep ing the trai ler as light as possi­
ble under the c ircumstances. Whenever poss i­
ble, transfer some cargo to the luggage com ­
partment of the tow veh icle while obse rving
tongue load requ irements and vehicle load ing
considerations.
Speed
The higher the speed, the more d iff icu lt it be­
comes for the driver to control the rig. Do not
drive at t he maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -pa rtic ularly
whe n going downhill.
Reduce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing.
Do n ot
try to sto p th e swaying by acc elerating .
Observe speed limits. In some areas, speeds
fo r vehicles tow ing tra ile rs a re lower than for
regular veh icles .
Always apply brakes early. When driving downh ill, shift into a lower gear to use the en ­
gine braking effect to slow the vehicle . U se of
the brakes alone can cause them to overheat
and fail.
Coolant tempe rature
The coo lant temperature gauge c> page 10
must be observed carefu lly. If the needle
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warning light •
i n t he i nstrument cluster starts flashing, pull
off the road, stop and let the engine
idle for
abo ut two min utes to prevent he at build-up .
_& WARNING
Anyone not proper ly restra ined in a mov ­
i ng vehicle is a t a much greater risk in an
accident . Never let anyone ride in yo ur car
who is not p roperly wea ring the rest raints
prov ided by Audi.

196 Cleaning and protection
-Never use sponges designed to remove
insects, or any kitchen scouring sponges
or similar products. They can damage
your paint finish .
- Never use a dry cloth or sponge to clean
the headlights. Only use wet cloths or
sponges to prevent scratches .
It is best
to use soapy water.
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
ing your vehicle. Never use a dry cloth or
sponge to clean the headlights . Only use
wet cloths or sponges to prevent
scratches.
It is best to use soapy water.
@ For the sake of the environment
Only wash the vehicle in facilities specially
designed for that purpose. This will reduce
the risk of dirty water contaminated with
oil from entering the sewer system. In
some areas, washing vehicles outside of
these facilities is prohibited.
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you
observe a few simple rules.
.. Before using the power washer, make sure
you have read and understood the WARN­
INGS¢
A in General information on
page 194 .
• Always follow the operating instructions for
the power washer .
• Make sure that the jet on the spray hose
produces a "fan shaped spray".
• Do
not hold the spray nozzle too close to
soft materials.
Never use a power washer to clean the power
top itself.
Keep a distance from soft materials such as
rubber hoses or insulating material as well as
sensors and camera lenses. When cleaning the vehicle with a power wash­
er
always follow the operating instructions.
This applies particularly to the operating pres­
sure and the spraying distance. Do not point
the spr ay directly at the seals around the side
windows, around the doors, on the rear lid or on the power top . Likewise, do not point it di­
rectly at tires, rubber hoses, insulation mate­
rial or sensors
¢page 198. Hold the spray
nozzle at least 1.3 ft (0 .4 m) away from the
vehicle.
Do not use a high-pressure power washer to
remove snow and ice .
Do not use a jet which sprays water in a direct
stream or one that has a rotating jet.
Water temperature should not exceed 140 °F
(60 °().
A WARNING "'--
Never wash tires with a jet that sprays wa -
ter in a direct stream . This could cause in­
visible damage to the tires and weaken
them, even if the spray is from a relatively
long distance and for a short time. Dam­
aged and weakened tires can fail and cause
accidents and personal injury.
(D Note
- Never use a power washer to clean the
power top itself.
- To avoid damaging your vehicle, always
make sure that there is sufficient dis­
tance between the spray head and soft
materials like rubber hoses, plastic parts
and sound-deadening materials as well
as sensors and camera lenses. Never aim
the spray head at the same point for a
long time . This also applies to cleaning
headlights and painted bumpers. Re­
member: the closer the nozzle is to the
surface of the material , the greater the
stress on the material.

Caring for vehicles with matte finish
paint
Applies to vehicles: with matte finish paint
Vehicles with matte finish paint require spe­
cial care due to the characteristics of the
paint.
Washing b y hand

216 Check ing and filling
temperatures stay below freezing point for
long periods.
Detergent addit ives in the o il w il l make fresh
oil look dark after the eng ine has been run­
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am age or m alfunc tions du e to lack of
m ainten ance
It
is essential that you change your oil at the
recommended in tervals using only engine o il
that complies with Audi oi l standard
VW 502 00. Your Limited New Vehicle War­
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance book let . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re­
pa ir Orders that all scheduled ma intenance
was performed in a t imely manner.
Eng ine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cool ing of internal engine components, a ll in­
ternal combustion eng ines consume a certa in
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typica lly, engines
with a specif ied break-in period (see
¢
page 187) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under norma l conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road condit ions . Further fac­
tors are the amount of oil d ilution from water
condensat ion or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to wear as mi
leage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the o il lev ­
el, see
Note .
If
the yellow engine oil leve l warning symbo l
I! in the instrument cluster lights up, you
shou ld check the oil leve l as soon as possib le
¢
page 217. Top off the oil at your earliest
convenience ¢

A WARNING '"---
Before you check anythi ng in the engine
compartment, always read and heed all
WARNINGS¢
A in Working in the engine
compartment on page 212.
(D Note
Driving w ith an insufficient o il level is like­
ly to cause severe damage to the engine .
(D Tips
-The oil pressu re warn ing display . is
not an indic ator of the oil l evel. Do not

erably ea ch time you r efu el, and alwa ys
before go ing on a long trip .
-If you have t he impression yo ur engine
consumes excessive amoun ts of o il, we
recommend that you consu lt an author­
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in m ind that the accurate measu rement of
oil consumption requ ires great care and
may take some time. An authorized Aud i
dealer has instructions about how to
measu re oil consumption accurately.

Have the battery checked when you take your
vehicle in for service. Yo u are well advised to
replace a battery that is older than 5 years.
W ith certa in types o f airbag deployment, the
battery is disconnec ted from the vehicle elec ­
trica l system for safety reasons
c::> &. in Re­
pair, care and disposal of the airbags on
page 154.
Di sconn ecting the battery t erminal s
Some vehicle functions (power w indow regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connec ted again. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs .
Vehicl es not driven for long p eriod s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cu t back or switched off .
This reduces energy consumption and main ­
tains starting capability over a longer per iod
