! ?) Engine speed limitation
Applies to: ve hicles with eng ine speed lim itat ion
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
a l once.
If the engine speed limitation was activated by
an engine contro l ma lfunction, the
ll:a indicator
light also turns on. Make sure that the speed
does not go above the speed displayed. Drive to
an author ized Audi dealer or authorized Audi
Service Facility immediately to have the malfunc­
tion corrected .
Q) Tips
Applies to: S models
The engine speed is limited when the engine
is cold
-the full engine output is not availa­

A WARNING ,.___
Do not assume the roads are free of ice based
on the outside temperature display . Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents.
(D Tips
-You can select the units used for tempera­
ture, speed and other measurements in the
Infotainment system.
- If your vehicle is stationary or if you are driv­
ing at very low speeds, the temperature dis­
played may be slightly higher than the ac­
tual temperature outside due to the heat ra­
diating from the engine.
- For information on the audio/video and nav­
igation* functions, refer to the separate In­
fotainment system operating manual.

Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof* are closed. If there is a bui ld-up of heat
inside the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode functions, except for defrost,
the blower only switches to a higher speed once
the engine coolant has reached a sufficient tem ­
perature.
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .

A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog .
- Become familiar as quickly as possible with
the correct use and function of the climate contro l system, especially with the defrost­
ing and defogg ing function.
58
- When the temperature is below freezing,
only use the windshield washer system after
the windshield has been warmed by the cli­ mate control system . The washer fluid could
freeze on the w indsh ield and impair v isib il i­
ty .
@ Note
-If you suspect that the climate contro l sys­
tem is damaged, switch the system
off to
prevent further damage and have it checked
by an authorized Aud i dea ler or authorized
Audi Serv ice Facility.
- Repa irs to t he Aud i climate control system
require special techn ical know ledge and
special tools. See an aut ho rized Aud i dea le r
or authorized Aud i Serv ice Fac ility .
@) For the sake of the environment
To save fue l, turn off cooling mode by press­
i ng the
IA/Cl button. This will a lso reduce
emissions.
(D Tips
- T o prevent i nterference with t he heat ing
and cooli ng outpu t and to p revent the win­
dows from fogging over, the a ir intake in
front of the windshie ld must be free of ice,
snow or leaves.
- C ondensation from the coo ling system can
drip and form a pudd le o f water under the
vehicle . This is norma l and does not mean
there is a leak.
- Th e energy management system may tem ­
porarily switc h
off certain functions, such as
the seat heating* or rear window defogger.
These systems are ava ilable again as soon
as the energy supply has been restored.

Driving
General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not dr ive at speeds
t hat will exceed 2/3 of the max imum pe rm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid fu ll acceleration during
this period . 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 place with each
other.
How the vehicle is driven d uring the first 1,000
miles (1 ,500 km) a lso affects the engine quality .
Drive at moderate engine speeds after the initial
break-in per iod, part icu larly when running a cold
eng ine . Th is 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 poo r roads, by cu rbs and on
s teep ramps, make su re t hat low-hang ing
compone nts such as the spo ile r and exha ust
system do not come into contact with these
or they could be damaged. This especially ap ­
plies to vehicles with low ground clearance
and veh icles that are heavily loaded.
Warming up/cooling down
Applies to: S models
By warming up/cooling down the engine carefu l­
ly, you can help red uce unnecessary stra in o n
your veh icle when driving in a sporty sty le .
64
The eng ine speed is lim ited when the engine is
cold - the full engine output is not availab le.
When the engine is at operat ing temperatu re,
the engine speed limitation moves to a h igher
RPM range. A lso, cold t ires may not have full
road gr ipping capab ilities until they have warmed
up .
Your vehicle a lso has an after-run cooling fea­
ture . However, cooling down is still important.
The eng ine and the brakes as well as the exhaust
system and the transmission become very hot
whe n driving in a spo rty style . Before you shut
t h e ve hicle off, you should cool down the vehicle
by d rivi ng a few miles at low speeds with l igh t ac ­
ce leration.
Driving through water on roads
Note the following to reduce the risk of vehicle
damag e when driving throug h water, for exampl e
on f looded roads:
- The water must not be any higher t han the bo t­
tom of the vehicle body.
- Do not dr ive faster tha n wal king speed .
& WARNING
After driving th ro ugh water or m ud, the effec ­
tiveness of the brakes may be red uce d due to
mo isture on the brake rotors and brake pads.
A few careful brake app lications shou ld dry
off the brakes and restore the full braking ef­
fect .
@ Note
-Vehicle components such as the engine,
t ransmiss ion, suspens ion or elect rical sys­
tem can be seve rely damaged by drivi ng
throug h water .
- Always switch the Start/Stop system* off
when driving through water
¢ page 70 .
(D Tips
- Determine the depth before driving throug h
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
