the front passenger 's side .
8/r Blower
Using the regu lator 8f?, you ca n manually adjust
the vo lume of a ir generated by the blower to your
p reference . The blowe r shou ld always run at a

The air
quality sensor that is designed for d iesel and
gasoline exhaust automatically sw itches the re­
circulation mode on or off depending on the level of pollutants in the o utside air.
In rec irculat ion mode, the air inside the vehicle is

T he system switches to recirculation mode when
driv ing in reverse when the engine is cold .
SP. Rear window defogger
If the rear window defogger is act ivated when
the ignit ion is swi tched on, the battery manage­
ment determines based on the battery charge if
i t is possible to turn on . Otherwise, the rear w in ­
dow defogger funct ions w it h the eng ine runni ng
and switches off automat ically after approxi­
mately 1 0 - 20 m inutes, depending on the out­

_& WARNING
-You should not use the recirculation mode
for an extended period of time, because no
fresh a ir is drawn in and the windows can
fog when coo ling mode is sw itched off. This
increases the risk of an accident .
-Individuals with reduced sensitivity to pain
o r temperature could develop burns when
using the seat heating function. To reduce
the risk of injury, these indiv iduals should
not use seat heating.
(D Note
To avoid damage to the heat ing elements in
the seats, do not kneel on the seats or place
heavy loads on a small area of the seat.
@ Tips
-The setting for the seat heating on the driv­
er's side is ass igned to the key that is in use .
-If the front passenger's seat heating is
turned on, it will not turn on again automat­
icall y if more than 10 minutes have passed
between switching the ign ition off and
switching it on again.

Steering wheel heating
Applies to: veh icles w ith steering whee l heating
The steering wheel rim can be heated.
"' Press the ~ ¢ page 15, fig. 11 button on the
mu ltifunction steering wheel to switch the
steering whee l heating on and off. The mes­
sage
Steering wheel heating: on/Steering
wheel heating: off
appears in the instrument
cluster display.
T he temperature is maintained at a constant lev­
el when steering wheel heating is switched on .
The steering wheel heating sett ings are stored
automat ically and assigned to the remote control
key that is in use .
If the steering wheel heating cannot be switched
on, the message:
Steering wheel heating : off ap­
pears. Drive to an authorized Audi dealer or au­
thorized Audi Service Facility immediately to have
the malfunction corrected.

Driving
When not being 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 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* .
(D 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 prop­ erty.
- 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,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
@ Tips
The consumpt ion 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
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back.
Fig . 83 Steering column : steering column adjustment lever
.. Tilt the lever -c> fig. 83 downward¢ ,&..
.. Bring the steering wheel into the desired posi­
tion.
.. Push the lever against the steering column un­
til it is secure.
A WARNING
Incorrect use of the steering wheel adjust­
ment and an incorrect seating position can
cause serious injuries.
- Only adjust the steering column when the veh icle is stationary so that you do not lose
control of the vehicle.
-
-Adjust the driver's seat or steer ing wheel so
that there is at least 10 inches
(25 cm) dis­
tance between your chest and the steering
wheelr::!>page250, fig. 217. If you do not
maintain this distance, the airbag system
will not be able to provide its full protec­ tion.
c:> page 250, fig. 217.
- If your physical characteristics prevent you
from sitting at least 10 inches
(25 cm) or
more away from the steering wheel, see if
an authorized Audi dealer or authorized
Audi Service Facility can provide adapters that will help.
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision. Always make sure
that the steering wheel is level with your
chest.

overhangs, carports or similar structures. Switch
the ignition off. Have the problem corrected by
an authorized Audi dealer or authorized Audi
Service Facility.
•• Electric drive: overheated! Safely stop
vehicle and check coolant
The coolant level is too low or the coolant tem­
perature is too high.
Stop the vehicle in the outdoors as soon as it is
safely possible. Switch the ignition off.
Read the important safety
precautions ¢.& in
Coolant on page 103
and check the coolant level

Checking and Filling
Coolan t loss usu ally indicates there is a leak. Im ­
m ed iately drive your v ehicle to an authorized
Aud i dea ler or authorized Aud i Serv ice Facility
and have the cooling system inspected. If the
coo ling system is not leaking, a loss can come
from the coolant boiling through overheating
and be ing pushed out of the cool ing system.
.&_ WARNING
- The coo ling system is under pressure . Do
not open the coolant expans ion tank cap
when the eng ine is ho t. This inc reases the
risk of burns .
- T he coo lant add itive and the coolant can be
d angerous to your healt h. For this reason,
keep the coolant in the origina l container
and away from children . There is a risk of
poisoning .
- When working in the engine compartment,
remember that the rad iator fan can switch
on even if the ign ition is switched off, which
increases the risk of in jury .
-
CD Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine. If this is the case , do not
cont inue driving. See an authorized Audi deal­
er or author ized Audi Service Facility for assis­
tance .

Checking the brake fluid level
Read the b rake fluid level on the br ake fluid res­
ervoir ¢ page 321, fig . 267. The brake f lu id leve l
must be between the MIN and MAX markings
¢ ,& .
The brake f lu id leve l is monito red automa tically .
Changing the brake fluid
Have the brake fluid changed regularly by an au ­
thorized Aud i dea ler or authorized Audi Service
Facility.
.&_ WARNING
- I f the b rake fl uid leve l is below the MIN
marking, i t can impair the bra king effec t
and driving safety, wh ich increase the r isk o f
an accident. Do not continue driving . See an
authorized A udi dealer or authorized A udi
Serv ice Facility fo r ass istance.
- If the brake fl uid is old, b ubbles may form
in the brake system dur ing heavy braking.
This would impair braking performance and
driving safety, which increases the risk of an
accident .
- To ensure the brake system functions cor­
rectly, only use brake fluids that comp ly
w ith VW standard S0 l 14 or
FMVSS- 116 DOT 4 .
CD Note
-If the brake f luid level is above the MAX
marking, brake fluid may leak o ut over the
edge of the reservoi r and result in damage
to the vehicle .
- Do not ge t any brake fl uid on the vehicle
