@ Tips
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, trip 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 most fuel when they are ac­
celerating. If you anticipate what is going to happen next, you will need to brake less and,
thus , accelerate less . Let the vehicle coast
whenever possible -for example when you see
that the next traffic light is red.
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 .
Fuel consumption, exhaust emissions and en­
gine noise increase disproportionately 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 con­
ditions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
~ Shut the engine off when you are not driving
the vehicle.
Driving and environment 199
~ Do not warm up the vehicle by letting the
engine run at idle.
It makes sense to shut off the engine in traffic
jams , when waiting for trains to pass at rail­
road crossings, or at traffic lights that have
long waits on red. Turning the engine off for
just 30 -40 seconds saves more fuel than is
burned starting the engine again.
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions 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
still warming up .
(D 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 serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dealer helps to ensure that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it also affects
fuel consump­
tion.
Check your oil each time you fill your tank.
The amount of oil 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 certain
mileage has been driven .

200 Driving and en vir onm ent
You must drive your vehicle about 3,000 miles
(5,000 kilometers) before you can properly
assess o il consumption.
This a lso applies to fuel consumption and en­
gine output.
0 Note
- Have yo ur vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main ­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the funct ion of the
emission control system and could lead
to damage .
- Do not alter or remove any component of
the Emi ssion Control System unless ap­
proved by the manufacturer .
- Do not alter or remove any dev ice, such
as heat shields, switches, ignition wires,
valves, wh ich are designed to protect
your vehicle's Emiss ion Control System
and othe r important veh icle compo­
nen ts.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.. Try to avo id driving short d istances with a
co ld eng ine .
The engine and ca talytic conver ter have to
reach their optimal
op erating temp eratur e to
reduce fuel consumption and noxious emis­
sions effect ively.
Jus t after s tarting, a cold engine in a mid-size
car only achieves a fuel economy of 6 -8 miles
per gallon (30-40 l/100 km) . After about a
ha lf a m ile, fue l economy climbs to 12 mpg
(20 l/100 km). Afte r abo ut
2 .5 m iles (4 km),
the eng ine is at its proper ope rat ing tempera­
ture and fue l economy has reached a norma l
l eve l. So you can see that you should avoid
short trips whenever possib le . T
he
ou tsid e tempe rature is also critical in this
regard . Your car consumes more fue l in the
winter than in the summer.

214 Check ing and filling
Using the proper engine o il is important for
the functionality and service life of the en­
g ine . Your engine was factory-filled with a
hi gh-quality oil which can usua lly be used
throughout the enti re year.
0 Note
Y our Limited New Vehicle Warranty does
not cover damage or ma lf u nctions due to
fa ilure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Ma intenance boo klet.
- Use only a high quality eng ine oi l that ex­
pressly complies w ith the Audi o il quality
sta ndard spec ified for your veh icle's en ­
gine . U sing any other oil can cause seri­
ous eng ine damage.
- Do not mix any l ubr ica nts o r othe r addi­
tives into the eng ine o il. Doing so c an
ca use eng ine dam age.
I f you need to add oi l and there is no ne
availab le tha t mee ts the Audi o il qua lity
s tandar d your engine requires, yo u may
ad d a tota l of no more than 0 .5 quart/liter
of a high-quality "synthetic"oil that meets
the following specifications.
- ACEA A3 or API S M with a viscosity grade
of SAE 0W-30, SAE SW-30 or
SAE SW -40.

Engine 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
cooling of i nternal engine components, a ll in­
ternal comb ustion eng ines consume a certa in amount of oil. Oil consumpt
ion varies from
engine to engine and may change significant ly
over the life of the engine . Typically, engines
with a spec ified break-in period (see
<=> page 196) consume more oil during the
break -in pe riod than they consume after o il
co nsump tion has stabilized.
Under normal cond itions, the rate of oil con ­
sumption depends on the q ua lity and viscos ity
of the oil, the RPM (revolut ions per minute) at
wh ich the engine is operated, t he ambie nt
temperature and road conditions . Fur ther fac­
tors a re the amount of oil dilut ion from wa ter
condensation or f ue l resid ue and the oxid a­
t ion level of the o il. As any engine is subjec t to
wear as m ileage builds up, t he oil consump­
tion may increase over time until replacement of wo rn components may become necessary.
W it h a ll these variab les coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alte rnative
to regu lar and frequent check ing of the o il lev­
el, see
Note .
If
the yellow engine oil level warning symbo l
in the instrument cluster
I!!! lights up, you
shou ld check the oil leve l as soon as possib le
<=> page 215. Top off the oil at your earliest
convenience
<=> page 215.
A WARNING
-Before you chec k anythi ng in the engine
com partment, always read a nd heed all
WAR NIN GS¢
& in Working in th e engine
compar tment on page 211.
{(D Note
Driving w it h an insufficient o il level is like­
ly to cause severe damage to the engine .
(D Tips
- The oil pressure warn ing display. is
not an indicator of the oil level. Do not
rely on it . Instead, check the oil lev el in
your engine at regular intervals , pref­
erably each time you refuel, and alway s
before going on a long trip. .,.

loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immediate ly.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed.
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch (10,5 mm), including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
q(D _ For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
Tires and wheels 253
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different sizes . Always make sure to follow the in­
structions provided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
([) Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severely dam­
age the wheelhouse and other parts of
the vehicle.
(D Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
vehicles with all-wheel drive.
