Warm and cold Climate control system
Description
The climate control system warms, cools and re­
moves humidity from the air in the vehicle interi­
or. It functions most effectively when the w in­
dows are closed. If there is a build-up of heat in ­
side the vehicle, ventilation can help to speed up
the cooling process.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
Key recognition
Certain settings are automatically stored and as­
signed to the remote contro l key being used .
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
control system, especially with the defrost­
ing and defogging function.
- When the temperature is below freezing,
only use the windshield washer system after
the windsh ield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshield and impair visibili­
ty .
(D Note
-If you suspect that the climate control sys­
tem is damaged, switch the system off to
Warm and cold
prevent further damage and have it checked
by an authorized Audi dea ler or authorized
Audi Service Facility.
- Repairs to the Audi climate control system
require special technical know ledge and
special tools. See an authorized Audi dealer
or authorized Audi Service Facility.
(® For the sake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter the
air.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogging over, the air intake in
front of the windshield must be free of ice,
snow or leaves.
- Condensation from the cooling system can
drip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak .
- The energy management system may switch
the seat heating* or rear window defroster
off temporarily . These systems are availab le
aga in as soon as the energy supp ly has been
restored.
- The flows through the vents under the rear
w indow . Make s ure the openings are not
covered when plac ing clothing on the lug­
gage compartment cover .

automatically adjuste d. In all heati ng mode func ­
tions except
defrost, the blower only switches to
a higher speed once the engine coolant has
reached a certain temperat ure.
~ Adjusting the blower
The blower speed can be adjusted in small incre­
ments using the dial @. The blower should al­
ways run at a low setting to prevent the windows
from fogging and to ensure a continuous ex­
change of air inside the vehicle. You can adjust
the volume of a ir generated by the blower to your
preference . To have the blower regulated auto­
mat ically, press the

Driving
General information
Breaking in
A new vehicle must be broken in, and the break­
in distance should be 1,000 mi les ( 1,500 km). Do
not drive at speeds that w ill exceed
2/3 of the
maximum permitted engine speed
(RPM) for the
first 600 miles (1,000 km) , and avoid full accel­
eration 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 during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in per iod, part icularly when running a cold
engine . This will reduce engine wear and improve
the mileage .
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 .
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for examp le
on flooded roads :
- The wate r must not be any higher than the bot­
tom of the vehicle body .
Driving
- 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 .
(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 oncoming 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 of fuel consumpt ion, the environ­
menta l 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 example, when you notice that the
next traff ic light is red . .,,.
55

Driving
Avoid full acc ele ra tion
You sho uld rare ly travel at the maximum vehicle
speed . High speeds cause a disp roportionately
high increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
It pays off to stop the engi ne, for examp le when
at rai lro ad crossings or tr affic lights with longer
red lights . Stopping the engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to resta rt the engine.
It t akes a very long time in idle to wa rm the en­
g ine up to operating tempe ra ture . Wear and
emissions are especially high in the warm-up
p hase . Therefore, yo u should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Have ma intenanc e performed r egularly
By having maintenance performed regular ly on
your vehicle, yo u can help to reduce f uel con­
sumpt ion before you even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term value but a l­
so impacts
fuel consumpt ion .
A poorly maintained engine can lead to fuel con­
sumpt ion that is 10% higher than normal.
A lso check the
oil le vel when refueling . The o il
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. Therefore, the oil
consumption can o nly be properly judged after
approx imately 3,000 m i (S,000 km) have been
d riven.
Avoid short trips
The engine and exhaust cleaning system must
reach the ir opt imal
operating temperature to ef­
fectively red uce consumption and em iss ions.
A co ld engine uses a disproportionately h igh
amount of fuel. The engine reaches operating
temperature and consumpt io n normalizes only
afte r approximately
four kilometers.
56
(D Note
Do not leave engine idling unattended after
starting. If warning lights sho uld come on to
i ndicate imprope r operation, they would go
unheeded. Extended idling also produces
h eat, which could result in overheating or
other damage to the vehicle o r other proper­
ty.
(D Note
- Have your ve hicle ma intained properly and
in accordance with the service recommenda­
t ions i n your Warranty
& M aintenance book­
let. La ck of prope r mai nte na nce as we ll as
imp roper use o f the ve hicle will impa ir the
func tion of the emission cont ro l sys tem and
cou ld lead to damage.
- Do not alte r or remove any compone nt of
the Emission Contro l System unless ap ­
proved by the man ufacturer.
- Do not alte r or remove any dev ice, such as
heat shields, switches, ig nition w ires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
important veh icle components.
(D Tips
The cons umption estimates as publishe d by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the r oad, which wi ll vary depending upon vehicle
l oad and speed, road a nd wea ther conditions,
tr ip length, etc.

Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back.
Fi g. 59 Lever on th e steering column
... Tilt the lever c:::> fig . 59 downward c:::> A
... Bring the steering wheel into the desired posi­
tion .
... Push the lever against the steering column un­
t il it is secure.
A WARNING
Incorrect use of the steering wheel ad just­
ment and an incor rect seating posi tion ca n
cause se rious injuries.
- Only adjust the steeri ng column when the
vehicle is stat ionary so that you do not lose
cont ro l of the ve hicl e.
- Adjus t the dr iver's seat or steering wheel so
that there is at least a 10 in (25 cm) d is­
t an ce betwee n your chest a nd t he s teering
w heel. If y ou d o not m aint ain this dis tan ce,
yo u will n ot be proper ly protected by the a ir­
bag system.
- If your phys ic al characteris tics p reven t you
from sit ting a t least 1 0 in ( 25 cm) or mo re
away from the steering whee l, see if yo ur
authorized Audi dea ler or autho rized Audi
Service Facility can prov ide adapters that
will help.
- If your face is leve l with the steering wheel,
the a irbag does not provide as much protec­
t io n during a collision. Always make s ure
tha t the steering wheel is leve l with yo ur
chest.
D rivi ng
-Always hold the steering wheel with your
hands i n the 9 o'clock and 3 o'clock pos i­
tions to reduce the risk of injury if the airbag
deploys.
- Never hold the steering wheel in the 12
o'clock position or with both hands on the
rim or the center of the stee ring wheel.
H old ing the steer ing whee l incorrect ly sig­
n ificant ly increases the r isk of injury to the
hands, a rms and head if the air bag deploys.

- To redu ce the r is k of p oisoni ng, never allow
the eng ine to run in confined spaces.
57

Driving
-Never turn off the engine before the vehicle
has come to a complete stop.
- The brake booster and power steering only
work when the engine is running. If the en­
gine is
off, you have to use more force when
steering or braking. Because you cannot
steer and brake as you usually would, this
could lead to accidents and serious injuries.
(D Note
Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately . This re­
duces unnecessary emissions.
{D) Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch
off af­
ter a certain amount of time . Make sure that
electrical equipment such as the exterior
lights are switched
off.
Stopping the engine
.,. Bring the vehicle to a full stop.
.,. Move the selector lever into the P position .
... Press the
I START ENGINE STOPI button

Emergency off function*
If it is absolutely necessary, the engine can also
be turned
off while driving at speeds starting at
4 mph (7 km/h). To switch the engine
off, press
the
! START ENGINE STOPI button twice in a row
briefly or press and hold for longer than two sec­
onds.
_&. WARNING
- Never turn off the engine before the vehicle
has come to a complete stop.
58
- Please note that the brake booster and pow­
er steering only work when the engine is
running. When the engine
off, you must use
more force to steer or brake the vehicle. Be­
cause the usual steering and braking capa­
bility is not available, the risk of accidents or
. . . . mJunes increases.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll.
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the
result of heat buildup or if the engine is al­
ready warm and the engine compartment is
also heated by the sun's rays.
(D Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after th@ engine is
switched
off and there is a risk of damaging
the engine . For this reason, let the engine run
at idle for approximately two minutes before
shutting it
off.
