Opening and clo sin g
@ Tips
- Do not leave valuables unattended in the ve­
hicle . A locked vehicle is not a safe!
- The LED in the driver 's door rail blinks when
you lock the vehicle . If the LED lights up for
approximately 30 seconds after locking,
there is a ma lfunction in the central locking
system. Have the problem corrected by an
authorized Audi dealer or authorized Audi Service Fac ility.

Economical and environmentally-friendly
driving
The amount of fue l cons umption, the env iron­
men tal impact and the wear to the engine,
b rakes and t ires dep ends mostly on your dr iv ing
style. W ith an anticipatory and economic driv ing
s tyle, f ue l consumption can be reduced by ap­
p roximate ly 10-15% . The following tips will help
you conserve the environment and your money at
the same time .
Anticipatory dr iving
A veh icle uses the mos t fu el when a cce le ra ting.
W hen you dr ive wi th ant icipat ion, you do not
need to brake as often and so you ac celerate less .
When possib le, let your ve hicle coast wit h a
gear
engaged ,
for example, when you notice that the
next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions a nd fuel con­
sumpt io n to ze ro (f uel shut-off dur ing decelera­
tion) .
Shift efficiently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fue l unnecessari­
ly .
Press down on the acce le rator peda l slowly and
avoid "k ick -down" .
66
Avoid full acceleration
You should rarely travel at the maxim um vehicle
speed. Hig h speeds cause a disproportionate ly
high increase in fue l cons umption, emissions and
traffic noise. Slowe r driving saves fue l.
Reduce idling time
The Start-S top system * helps to re du ce the idling
time automat ic all y. In ve hicles withou t the Star t­
Stop system *, i t is efficient to sw itch the engine
off when stopped at railroad crossings and long
red lights. Stopping the engine for 30-40 sec­
onds a lready saves more fue l than the amo unt of
extra fue l needed to restart the engine.
It takes a very long time in id le to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm- up
phase . Therefore, you shou ld begin driving im­
med iate ly after starting the engi ne. Avoid high
RPMs wh ile doing this.
Have maintenance performed regul arly
By having maintenance pe rformed reg ula rly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The
mainte nance condition of your vehicle not on ly
affects traffic safety and long- term value but al­
so im pacts
fuel consumption . A poorly main­
ta ined engine can lead to fuel consump tio n t hat
i s 1 0% hig he r th an no rm al.
Avoid short trips
The eng ine and exhaust clean ing system must
r each their op tima l
operating temperature to ef­
fect ively reduce consump tion a nd emissions.
A cold engine uses a d isproportionately high
amount of fuel. T he eng ine reaches operat ing
temperat ure and cons umption no rma lizes only
af ter approximate ly
2.5 miles (4 km).
Check the tire pressu re
To save fue l, make sure the t ires are always in­
flated to t he correct press ure
r=':>page 221. The
fuel consumpt ion can increase by 5% if the pres­
s ur e is only 0 .5 bar too low . Due to t he i ncreased
r oll ing resis tance, low tire p ressures w ill also

lead to greater tire wear and will affect driving
behav ior.
Do not drive on
winter tires year-round , as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­ moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62-75 mph (100-120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
CD Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty .
CD Note
-Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book ­
let. Lack of proper maintenance as well as
improper use of the vehicle 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 shields, switches, ignition wires,
Driving
valves , which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
(D 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 vehicle
load and speed, road and weather conditions,
trip length, etc .
Steering
Manual steering wheel position adjustment
Applies to: vehicles with manual steering wheel adjustment
The steering wheel position is adjustable up and
down and forward and back.

_& WARNING
~ -
Improper use of steering wheel adjustment
and improper seating position can cause seri ­
ous personal injury.
-Adjust the steering wheel column only when the vehicle is not moving to prevent loss of
vehicle control.
- Adjust the driver's seat or steering wheel so
that there is a minimum of 10 in (25 cm) between your chest and the steering wheel

\.J ' -Do not drive until the fuel tank becomes
complete ly empty . The engine cou ld mis­
fire. Unburned fuel could also get into the
exhaust system and this cou ld cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requ ir­
i ng its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
book let.
- Lack of proper maintenance as we ll as im ­
proper use of the vehicle will impair the
function of the emission control system and could lead to damage.
® For the sake of the environment
Even when the Emission Control System is op ­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erat ing states. This depends on the su lfur
content of the fuel being used. Using a differ­
ent brand of fue l may help, or filling the tank
w ith lead-free super grade gasoline .
Diesel particulate filter
Applies to: veh icles with diesel engine
The diesel particulate filter filters nearly all of
the soot particles out of the exhaust. The filter
cleans itself automatically under normal driving
conditions . If the filter cannot clean itself (for ex­
ample , because you are only driving short distan­
ces), the fi lter becomes clogged with soot and

the high temperature of the diesel particu­
late filter could start a fire.
- Do not apply an underbody protectant in the
exhaust system area or a fire could start.
Engine compartment
Working in the engine compartment
Special care is required if you are working in the
engine compartment
For work in the engine compartment, such as
checking and filling fluids, there is a risk of in­
jury, scalding, accidents, and burns. For this
reason, follow all the warnings and general
safety precaution s provided in the following in·
formation . The engine compartment is a dan­
gerous area on the vehicle.
¢ ,&..
A WARNING
= =--
- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
-Select the P selector lever position.
- Let the engine cool down.
- Never open the hood when there is steam or
coolant escaping from the engine compart­
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping .
- Keep children away from the engine com­
partment .
- Never sp ill fluids on a hot engine. These flu­
ids (such as the freeze protection contained
in the coolant) can catch fire.
- Avoid short circuits in the electrical system.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm . The
coo ling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a

\.J ' Using the proper 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
yea r.
Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions d ue to failure
to follow rec ommended maintenance and use
requireme nts as s et forth in the Audi Owner's
Manual and Warranty & Maintenance booklet .
- Use only a high quality engine oi l that ex-
pressly complies with the Au di 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 qt (0.5 l) of a h igh-quali ty
"synthet ic"oil that meets the following speci ­
fications.
- Applies to: gaso line engine: ACEA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE 5W-30 or SAE 5W-40.
- Applies to: diesel engine: ACEA C3 or API CF
with a viscosity grade of SAE OW-30 o r
SAE 5W-30 .
- For more information about engine oil that
has been approved for your vehicle, please
contact e ither your authori zed Audi dea ler
or Audi Customer Relat ions at
1 (800) 822-2834 or visit our web site at
www .audiusa .com or www .aud ica nada.ca.
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 lub rication and cool­
ing of in ternal engine componen ts, all internal
Ch eck ing and Filling
combustion engines consume a certain amo unt
of oil. Oil consumption vari es from engin e to en­
gine and may change s ignificantly over the life of
the engine . Typ ically, engines w ith a specified
break-in period (see¢
page 65) consume mo re
o il during the break -in per iod than they consume
after o il consumption has stab il ized .
Under normal cond itions, the rate of oil con ­
sump tion depends on the qu ality and viscos ity of
the oil, the RPM (revolutions per minute) at
wh ich the engine is operated, the amb ient tem­
perature and road co ndit ions. Further facto rs a re
the amount of oi l di lution from wate r condensa ­
tion or fuel resid ue and the oxidat ion level of the
o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unti l replac ement of worn components may
become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be estab ­
li sh ed or sp ecified . There is no alternative to reg­
u lar and frequent checking of the oi l level, see
Note .
If the yellow engine oil leve l warning symbo l in
the instr ument cluster
Ill lights up, yo u should
check the oi l level as soon as possible
¢
page 204. Top off the o il at your earliest con­
venience ¢
page 204 .
A WARNING
-Before you check anyt hing in the engine com -
partment, always read and heed all WARN­
INGS
¢ .&. in Working in the engine compart­
ment on page 199.
{(D Note
Driving w it h an insufficient oil level is likely to
cause severe damage to the eng ine .
(D Tips
-The oil pressure wa rn ing display. is not
an indicator of the o il leve l. Do not rely on
i t . Instead, check th e oil level in your en­
gine at regular interval s, preferably each
time you refuel, and alway s before going
on a long trip .
203

Wheels
As an added safety feature, your vehicle has been
equipped with a tire pressure mon itor ing system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­
ly under-inflated . Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and ti re tread life,
and may affect the vehicle's handling and stop­
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under- inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale . When the system detects a
malfunction, the telltale will flash for approxi ­
mately one m inute and then remain cont inuously
illuminated . This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists .
When the malfunct ion indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

Tire pressure monitoring system
Applies to: vehicles with Tire Pressure Monitoring System in­
dicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 194 Instrumen t cl uster : indicator l ig ht with me ssage
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires. If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
Rt] and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
¢ page 231. The tire pressure mon i­
toring system only monitors the tire pressure you have stored . Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢page 221, fig. 193.
Tire tread circumference and vibrat ion character­
istics can change and cause a tire pressure warn­
ing if :
- the tire pressure in one or more tires is too low.
- the tire has structural damage.
- the tire was replaced or the tire pressure was
changed and it was not stored¢
