!?i Engine speed limitation
(ill Maximum engine speed: XXXX rpm
The engine speed is automatically limited to the
speed displayed in the instrument cluster. This
protects the engine from overheating.
The engine speed limitation deactivates once the
engine is no longer in the critical temperature
range and you have released the accelerator ped­
al once.
If the engine speed limitation was activated by
an engine control malfunction, the
II indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam­
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im­
mediately to have the malfunction corrected.

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 and fuel con ­
sumpt ion to zero (fuel shut-off dur ing decelera­
tion) .
Shift efficiently
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fuel unnecessari­
ly.
Applies to: vehicles with manual transmission
Shift as soon as possible from first to second
gear. S hifting to the next highest gear at approxi­
mately 2,000 RPMs if poss ible is recommended.
Applies to: vehicles with automatic transmissions
Press down on the acce le rator peda l slowly and
avoid "kick -down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Driving more slowly saves fuel.
Reduce idling time
The Start/Stop system* he lps to reduce the idling
time automatically. In vehicles without the Start/
Stop system*, it is efficient to switch the engine
off when stopped at railroad cross ings and long
r ed lights. Stopping the engine for 30-40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine.
It takes a very long time in idle to warm the en­
g ine up to operating temperature. Wear and
emissions are especially h igh in the wa rm-up
phase . Therefore, you should begi n driving im­
mediately a fter starting the engine . Avoid high
RPMs while do ing this .
Have maintenance performed regularly
By having maintenance performed regu larly on
your veh icle, yo u ca n he lp to reduce f uel con-
<(
~ sumption before yo u even start to drive. The
N ~ maintenance condition of your vehicle not only
8 affects traffic safety and long-term value but a l­
'° 3 Driving
so impacts fuel consumption . A poorly main ­
tained engine can lead to fuel consumption that is 10% higher than norma l.
Avoid short trips
The eng ine and exhaust cleaning system must
reach their optimal operat ing temperatu re to ef­
f ectively reduce consumption and emissions.
A cold engine uses a disproportionately high
amount of fue l. The engine reaches operating
temperat ure and consumption normalizes on ly
after approximate ly 2.5 miles (4 km).
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct press ure
~page 351. The
fuel consumption can increase by 5% if the pres­
s u re is only 0.5 bar too low. Due to the increased
rolling resistance, low tire pressures wi ll also
l ead to greater tire wear and will affect driving
behavior.
Do not drive on winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
S in ce eve ry po und of ext ra weight increases f uel
consumption, a quick inspection of the luggage
compartment may be worth it to avoid unneces ­
sary weight .
When not be ing used, a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. This will save you approximately 12% fuel
at speeds from 62 -75 mph (100 - 120 km/h) .
Save energy
The eng ine drives the generator, which generates
electric ity; the fuel consumpt io n also incr eases
with the demand for electr icity. The refore, switch
electrical eq uipment off when you no longer
need it . Examples of equipment that uses a lo t of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
@ Note
Do not leave engine idling unattended after
starting. If warning lights shou ld come on to
indicate improper operation, they would go

ou t onto the ho t engine and exhaust system
when the engine is running, beca use this is
a fire hazard .
- Always clean skin thoroughly if it comes into
contact with engine oil.
(D Note
-The engine o il level must not be under the
" min" marking, because this incre ases the
risk of engine damage.
-If the message II Pl ea se redu ce oil lev el
appears, there is too much oil in the eng ine
and there is a risk of damaging the cata lytic
converter and engine. Do not start the en­
gine . Contact an authorized A udi dealer or
authorized Audi Service Fac ility to have ex­
cess engine o il extracted if necessary .
- Do not mix any add it iona l lubricants into
the engine oil. Damage caused by such add i­
t ives is not covered by the warranty.

Wheels
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­
ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8-
pillar, always follow the specifica­
tion on the 8-pillar label

352
(i} For the sake of the environment
-Tire pressure that is too low
increases fuel consumption.
-Fuel consumption may also in­
crease when driving with the
comfort tire pressure is se­
lected .
(D Tips
Audi recommends using the
tire pressure specified for a
normal load
¢ table on
page 353
or for a full load
when the vehicle is partially loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­ mended tire pressures in cold
tires according to the load and
the size of the tires installed.

Wheels
@ For the sake of the environment
Reinstall su mmer tires at the appropriate
time, because they pro vide better handling
when roads are free of snow and ice. Summer tires cause less road noise, tire wear and fuel
consumption.
@ Tips
You can also use all season tires instead of
w inter t ires. Please note that in some coun­
tries where w inter tires are required, only
w inter t ires with the
& symbol may be per­
m itted.
Snow chains
Snow chains not only imp rove the dr iving in w in ­
ter ro ad conditions, b ut also the brak ing .
.,. Only install snow chains o n the front wheels .
.,. Check and cor rect the seating of the snow
c h ains after dr iv ing a few feet, if ne cessa ry . Fo l­
low the ins tructions from the m anufactu rer.
.,. Note the maximum permit ted speed when driv ­
ing with snow chains. Do not exceed 30 mp h
(SO km/h) .
Use of snow chains is o nly pe rmitted with certain
rim/tire combinations due to technical reasons .
Check with an authorized A udi dealer or author­
ized Audi Service Fac ility to see if you may use
snow chains.
Use fine-mesh snow chain s. They must not add
more t han 0.53 in (13 .5 mm) in height, includ ing
the chain lock .
You mus t remove the snow chains on roads w it h­
out snow . Otherwise, you could impai r dr iving
abi lity and damage the tires .
A WARNING
Us ing inco rrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
control, which increases t he risk of an acc i­
dent .
358
(D Note
Snow chains can damage the rims/whee l cov ­
ers * if the c ha ins come into direct contact
with them . Remove the whee l cove rs* first.
Use coated snow chains.
(D Tips
When using snow chains, it may be usefu l to
switch on sport mode

Low-profile tires
App lies to: vehicles with low-profi le tires
Your vehicle is equipped with low-profile t ires* at
the factory. Compared to other tire/r im combina­
t ions, low-profi le tires offer a w ider t read surface
and a la rger r im diamete r with shorter tire side­
walls. This results in an agile dr iv ing style. How­
ever, i t may reduce the leve l of com fort and in ­
crease road noise whe n driving on roads in poo r
condition .
Low-p rofile ti res ca n become damaged mo re
q uickl y than st andar d tires when dr iv ing ove r
l a rge bumps, potholes, manhole covers, speed
b u mps and curbs . Therefore, it is particularly im ­
portant to maintain the correct tire pressure
r::> page 3 51.
To reduce the risk of damage to the tires and
rims, drive very caref ully on poor roads.
Check your wheels regu larly eve ry 2,000 m i
( 3 ,00 0 km) for d amage. For ex am ple, c heck for
bulges/crac ks on the tires or deformations/
c racks on the rims.
Af ter a heavy imp act o r damage, have the tires
and rims i nspected or replaced immedia tely by
an a uthorized Audi dea le r or authorized Audi
Service Facility .
Low-p rofile ti res c an wear out f aster than stand­
a rd tires.
Summer tires are not suitable fo r cold weather,
snow or black ice. If yo u are d rivi ng in these con­
d it ions, use wi nter or a ll season tires
