Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
You should shift to the next lowest gear when
the engine speed is below 1,SOO RPM . The begin­
ning of the red zone in the tachometer indicates
the maximum permissible engine speed for all
gears once the engine has been broken in and
when it is warmed up to operating temperat ure.
Before reaching the red zone, you shou ld shift in­
to the next higher gear, choose the Dor S selec­
tor lever position, or remove your foot from the
accelerator pedal.
CD Note
The needle in the tachometer @Q page 8,
fig. 3 may only be in the red area of the gauge
for a short time or there is a risk of engine
damage.
@ For the sake of the environment
Upshifting ea rly helps you to save fuel and re­
duces operating noise.
Fuel level
The fuel level indicator only operates when the
ignition is switched on.

Driving
General information
Breaking in
A new vehicle must be broken in for the first
1,000 mi les (1,500 km). For the first 600 miles
(1,000 km), do not drive at speeds that are more
than 2/3 of the maximum permitted RPM, avoid
full acce leration, and do not tow a trailer . You
may gradually start increasing the RPM and the
speed between 600 miles (1,000 km) and 1,000
miles (1,500 km) .
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into p lace with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initia l
break-in period, particularly when running a cold
engine . This will reduce eng ine wear and improve
the m ileage .
Do not drive at too
low of an engine speed (RPM).
Shift down if the engine stops running "smooth­ ly". Extremely high eng ine speeds are automati­
cally reduced.
Reducing the risk of vehicle damage
([) Note
When driving on poor roads, by curbs and on
steep ramps , make su re that low-hang ing
components such as the spoiler and exhaust
system do not come into contact with these
or they could be damaged. This especially ap­
plies to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driv ing through water, for example
on flooded roads :
- The water must not be any higher than the bot­
tom of the vehicle body.
D riving
- Do not drive faster than walking speed.
A WARNING
After driv ing through water or mud, the effec­
tiveness of the brakes may be reduced due to moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes and restore the full braking ef­
fect .
(D Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water.
(D Tips
-Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
- Avoid dr iving through salt water, because
this can cause corrosion .
Economical and environmentally-friendly
driving
T he amount o f fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style. With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­ proximately 10-15% . The following tips will help
you conserve the environment and your money at
the same time .
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not
need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a
gear
engaged,
for examp le when you notice that the
next t raffic light is red. This produces an engine
llll-
57

Driving
braking effec t, which he lps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt ion to zero (fuel shut-off during dece lera­
tion) .
Shift effici en tly
Upshift ing earlier is an effective way to save fuel.
Staying in a gear too long uses fue l unnecessari ­
ly.
P ress down o n the acce le ra tor peda l slowly and
avoid " kick -down ".
Avoid full acceleration
You should rare ly trave l at the maximum vehicle
speed. High speeds cause a d isproportionately
h igh inc rease in fuel consump tion, emissions and
tr affic no ise. Slower driving saves fuel.
Reduce idling time
There are benefits to stopp ing the engine, for ex ­
ample when at railroad crossings or traffic lights
with longer red lights. Stopping the engi ne for
30 -40 seconds already saves mo re fuel than the
amount of extra fuel needed to restart the en­
gine.
It takes a very long time in idle to wa rm the en­
g ine up to ope ra ting tempe ra tu re. Wea r and
emissions are especially high in the wa rm -up
phase . Therefore, yo u should begi n driving im ­
mediately after starting the engine. Avoid high
RP Ms while doing t his .
Have maintenance performed r egularly
By having m ainten ance perfo rmed regu larly on
your ve hicle, yo u can he lp to reduce f uel con­
sumpt ion befo re yo u even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long-te rm value but a l­
so impacts
fuel consumpt ion . A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Also check th e
oil level when refueling . T he oil
consumption
depends large ly on the engine load
and speed. It is normal for the oil consumpt ion
of a new eng ine to reach its lowest point only af ­
ter a certain amount of use. Therefo re, the oil
consumpt ion can o nly be properly judged after
58
approximately 3,0 00 miles (S,000 km) have been
driven .
Avoid short trips
The eng ine and exhaust clean ing system mus t
r each their optima l
operating temperature to ef­
fe ct ively reduce consump tion and emissions.
A cold engine uses a d isp roportionately high
amount of fue l. The engine reac hes operat ing
temperat ure and cons umption no rmal izes on ly
a fter approximate ly 2.5 m iles (4 km) .
Check the tire pressure
To save fuel, make sure the t ires are always in­
flated to the correct pressure ~
page 175. The
fuel consumpt ion can increase by 5% if the p res ­
s ur e is on ly 0.5 bar too low. Due to the i ncreased
rol ling resis tance, low tire p ressures w ill also
l ead to greater tire
wear and will affect driving
behavior .
Do no t drive on
winter tir es ye ar-r ound, as this
will consume up to 10% more f uel.
Eliminate unnecessary weight
S ince every po und of ext ra weight increases fuel
consump tion , a quick inspect io n of the luggage
compartmen t may be wo rth it to avoid unneces ­
s ar y we ight.
When not be ing used, a roof rack shou ld be re­
moved to decrease the w ind resistance of the ve­
hi cle. This will save yo u ap prox imately 1 2% fue l
at speeds from 62 -75 mph (100 -12 0 km/h).
Save energy
The eng ine drives the generator, which generates
e lectric ity; the fuel consumpt io n also increases
with t he demand for e lectricity . T he refore, sw itch
electrica l eq uipm ent off whe n you no longe r
need i t. Exa mples of eq uipme nt tha t uses a lo t of
energy a re air blowe rs at a high setting, the rea r
window defogger and seat heating* .
([) Note
-Do not leave engine idling un attended afte r
sta rting. If warn ing li ghts should come on
to ind icate improper ope ration, they wou ld
go unheeded . Extended idling also pro duces .,.

Using the prope r engine oil is important for the
functionality and s ervice life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year .
Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's Manual and Warranty & Maintenance booklet .
- Use only a high quality engine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine.
Using any o ther oil can cause serious engine
damage.
- Do not mix any lubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
@ Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0 .5 quart/li ter of a h igh-quality
"synthet ic"oil that meets the following speci ­
fications.
- ACEA A3 or API SM with a v iscosity grade o f
SAE OW-30, SAE SW -30 or SAE SW-40.

Engine oil consumption
T he engine in your vehicle depends on an ade­
qua te amoun t of oil to lubricate and cool all of
i t s moving par ts.
In order to provide effective lub rication and coo l­
ing of in te rnal engine components, a ll internal
combustion engines consume a cer tain amount
of oil. Oil consumption varies from engine to en ­
g ine and may change sign ificantly over the life of
the eng ine . Typically, eng ines with a spec ified
Ch eck ing and Filling
break-in period (see ¢ page 57) consume more
oi l during th e break-in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscos ity o f
the oil , the RPM (revolutions per minut e) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from w ater condensa­
tion or fuel resid ue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
t ime unt il repla cement of worn components may
become necessary.
With al l these variables coming into play, no
standard rate of o il consumption can be estab­
l ished or spec ified . T he re is no alte rnative to reg­
u la r and fre quent chec king of the o il level , see
Note .
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up , you sho uld
check the o il level as soon as possible
¢ page 160. Top off the o il at your earliest con­
venience.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN ­
INGS¢ .&.
in Working in the engine compart­

@ Fo r the sa ke of the env ironment
- Engine oi l should never enter the sewer sys­
tem or come into contact with the ground
under any circumstances.
- Pay attention to legal requirements when
disposing of empty oil containers.
The engine oil consumption may be up to 0.5 quart/600 m iles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be higher during the
first 3,000 miles (5,000 km). The engine oil
level must be checked regularly . It would be
best to check each time you refuel your vehi­
cle and before long dr ives.
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion.
Before you check anyth ing in the eng ine compart­
ment,
alw ays r ea d and heed all WARNINGS Q .&.
in Working in the engine compartment on
page 155.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
n ance booklet. This is very important because the
l ubri cat ing propert ies of o il diminish gradually
d ur ing normal vehicle use.
Under some c ircumstances the eng ine o il should
be changed more frequently . Change oil more of­
ten if yo u drive mostly short distances, ope rate
the vehicle in d usty areas or under predominant ly
stop-and -go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
l ook da rk after the engine has been running for a
short time. This is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of p roper disposal, along
with the special tools and necessa ry expertise re­
qu ired, we strong ly recommend that you have
Ch eck ing and Filling
your oi l changed by an authorized Audi dealer or
a qualified service station .
If yo u choo se to ch ange yo ur oil your self, please
note the follow ing important info rmation:
A WARNING
=
To reduce the risk of persona l injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protect ion .
-
-To redu ce the r is k of burns from hot eng ine
oil, let the engine cool down to the touch.
- W hen remov ing the oil d rain plug w ith your
fingers, stay as far away as possib le. Always
keep your forearm parallel to the ground to
he lp prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one la rge enough to hold at
least the tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water.
(D Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adverse ly affect yo ur Audi Limited New Vehi­
cle Warranty.
@ For the sa ke of the environment
- Before chang ing your oi l, first make sure
you know where you can properly d ispose of
the used oil.
- Always dispose of used engine o il properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
