Adjusting the temperature
Temperatures between 60 °F ( +16 °C) and 84 °F
(+28 °C) can be set . Outside of this range,
LO or
HI will appear in the climate control system dis­
p lay . At both of these settings, the climate con ­
trol system runs continuously at maximum cool­
ing or heating power. There is no temperature
regulation.
~ Adjusting the amount of air
You can adjust the airf low manually to su it your
needs. The blower should always run at a low set ­
ting to prevent the windows from fogging and to
ensure a continuous exchange of air inside the
vehicle. To have the airflow regulated automat i­
cally, press the
IAUTO I button.
~ Adjusting the air distribution
You can manually select the vents where the air
will flow. To have the a ir distribution regu lated
automatically, press the
IAUTO ! button.
[il /~*Adjusting seat heating/ventilation*
Pressing the button switches the seat heating/
venti lation on at the highest setting (level 3). The
LEDs indicate the temperature level. To reduce
the temperature, press the button aga in. To
sw itch the seat heating/venti lation off, press the
button repeatedly until the LED turns off.
After 10 minutes, the seat heating/ventilation
automatically switches from level 3 to level 2.
l The windshield and side windows are defrosted
or cleared of condensation as quickly as possible.
The maximum amount of air flows mainly from
the vents below the windshield. Recirculation
mode switches off. The temperature should be
set to approximately 72 °F (22 °().
The
IAUTO I button switches the defroster off .
IQiil R EARI Switching the rear window defogger
on and off
The rear window defogger only operates when
~ the engine is running. It switches off automati-....

This is stored until the ignition is switched off.
I SYNC! Synchronization*
When synchron ization is switched on, the set­
tings for the driver's side are applied to the front
passenger's side (except for seat heating/ventila­
t ion*). The rear is also synchronized in vehicles
with the 4- zone deluxe automatic climate control
system*. Synchronization switches off if the set­
t in gs are adjusted on the front passenger's side
or in the rear*.
You can synchronize the sett ings in a row by
pressing and holding a knob. For example, to ap­
ply the sett ings for the front passenger's side to
the driver's side, press and hold the knob on the
front passenger 's side .

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 .
New tires
If your vehicle is running on new tires, drive pa r­
ticularly careful for the first 350 miles (500 kilo­
meters) after fitting .
.&_ WARNING
-
New tires tend to be slippery and must also
be "broken-in". Be sure to remember this dur­
ing the first 350 miles (500 kilometers).
Brake gently . Avo id following closely behind
other vehicles or other situations that might
require sudden, hard brak ing.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low-
Driving
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged .
T h is is espec ially true for veh icles with low-s lung
chass is (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 example
on flooded roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faste r than walk ing speed.
.&_ WARNING
=
After driving through water or m ud, 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 sys­
tem can be severely damaged by driving
through water.
- Always switch off the Start/Stop system
when driving through water r::;,page
78.
{i) 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 .

Driving
Economical and environmentally-friendly
driving
The amount of fue l consumption, the environ ­
mental impact and the wear to the engine,
brak es and tir es d epends mostly on your driving
style. W ith an anticipatory and economic driv ing
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 .
Anticip atory d riving
A vehicle uses the most fuel when acce lerating.
When you drive with ant ic ipat ion , you do not
need to brake as often and so you accelerate less .
When possible, let your ve hicle coast w ith a
g ear
e ngag ed ,
for example , when you notice that the
next traffic light is red. This produ ces a n eng ine
b raking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (f uel shut-off during decelera ­
tion).
Shift effici ently
An effective way to save f uel is to upshift earlie r.
Staying in a gear too long uses fue l unnecessari ­
ly. Press down on the accelerator pedal slowly
and avoid "k ick-down".
Avoid full acceleration
You sho uld rare ly t ravel at the maximum vehicle
speed. High speeds cause a disp roportiona tely
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
The Start-Stop system * helps to reduce the id ling
time automatically . In vehicles witho ut the Start­
S top sys tem* , it is efficient to switch the eng ine
off when stopped at ra ilroad cross ings a nd long
red lights . Stopping t he 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 wa rm the en­
gine up to operating temperature . Wea r and
emissions are especially high in the warm -up
phase. Therefore, yo u should begin driving im-
74
mediate ly after s tarting the engine . Avoid high
RPMs whi le doing this.
Have maintenance performed regularly
By having maintenance pe rformed regu la rly on
you r vehicle, you can help to reduce fuel con ­
s u mption before you even sta rt to drive. The
maintenance condition of your vehicle not on ly
affects traffic safety and long-term value but al ­
so impacts fuel consumption. A poorly main­
ta ined engine can lead to fuel consumption that
i s 10% higher than normal.
Avo id short trip s
The engine and exha ust cleaning system must
reach their optima l operating temperature to ef­
fect ive ly reduce consumpt ion and emissions.
A cold engine uses a d isproportionately high
amount of fue l. The engine reaches operating
temperat ure and cons umption no rmalizes on ly
after approximate ly four kilometers.
Check the tire pre ssure
To save fuel, ma ke sure the tires are always in­
flated to t he corre ct pressure
¢ page 291 . The
fuel consumption can increase by 5% if the pres­
sure is only 0 .5 bar too low. Due to the increased
roll ing resistance, low tire pressures w ill also
lead to greater tire wear and will affect driving
behavior.
D rive with summer tires when possib le because
th is can increase fue l economy by up to 10%.
Eliminate unnecessary we ight
Since eve ry po und of extra weight increases f uel
consump tion, it pays to remove any unnecessa ry
weight .
A roof rac k increases the w ind resis tan ce on the
vehicle and shou ld be removed when it is not
needed . You will save approximately 12% o f you r
fuel when at speeds from 62-75 mph (100-120 km/h) .
Save energy
The eng ine d rives the genera tor , which gene rates
e lectric ity; the fuel consumpt ion also increases
with t he demand for e lec tricity . T he refore, switch ..,_

"' " "' .... 0 0 :r electrical equipment off when you no longer
need it. Examples of equipment that use a lot of
energy are a ir blowers at a high setting, the rear
w indow defogger and seat heating*.
CD Note
Do not leave engine idling unattended after
starting . If warning lights should come on to
ind icate improper ope ration, they wou ld go
unheeded. Extended idling also produces
heat, wh ich could result in overheat ing 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 you r War ranty
& Ma intenance book­
l et. Lack of p roper maintena nce as well as
i mproper use of the vehicle will imp air the
funct ion of the emission contro l system and
could lead to damage.
- Do not alter or remove any component of
the Em ission Control System un less ap­
proved by the manufacturer .
- Do no t alt er or remove any devi ce, such as
heat shie lds, switches, ignition wires,
valves, which are designed to protect your
vehicle's Em ission Control System and other
i mportant veh icle components .
@ Tips
The consumption estimates as published by E NVIRONMENTAL 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 condi tions,

Driving
-If physical limitations prevent you from sit­
ting 10 in (25 cm) or more from the steer­
ing wheel, check with your authorized Audi
dealer to see if adaptive equipment is avail­
able .
- If the steering wheel is aligned with your
face, the supplemental driver's airbag can ­
not prov ide as much protection in an acci­
dent. Always make sure that the steering
wheel is aligned with your chest.
-Always hold the steering wheel with your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of personal injury if
the driver's airbag deploys.
- Never hold the steer ing wheel at the 12
o'clock position or with your hands inside
