-The windshield wiper system must be
switched off (lever in position @) before us ­
i ng a car wash. This prevents the wipe rs
from sw itching on unintentionally and ca us­
i ng damage to the w indshie ld w iper system .
(D Tips
-The windshield wipe rs switch off w hen t he
i gnition is switched off. Yo u can act ivate the
windsh ield wipers after the ign ition is
switched back on by moving the windsh ield
wiper leve r to any pos it io n.
-Worn or dirty windshield wiper blades result
i n streak ing . This can affect the ra in se nsor
f u nct io n. Check yo ur windsh ield wiper
blades regularly.

(D Note
-Only fold the windshield wipers away when
they are in the service position. Otherwise,
you risk damaging the paint on the hood or
the windshield wiper motor.
- You should not drive your vehicle or press
the windshield wiper lever when the wiper arms are folded away from the windshield .
The windshield wipers would move back in­
to their orig inal position and could damage
the hood and windshield .
(D Tips
- You can also use the service position, for ex­
ample, if you want to protect the windsh ield
from icing by using a cover.
- You cannot activate the service position
when the hood is open .

Adjusting the magnetic zone
Applies to: ve hicles w ith d ig ital compass
The magnetic zone must be adjusted correctly for the compass to read accurately.
Fig. 61 Magnetic zone map
~ Press and hold the button CD~ page 57, fig . 60
until the number of the magnetic zone appears
in the interior rearview mirror.
~ Press the button CD repeatedly to select the
correct magnetic zone . The selection mode
turns off after a few seconds.
Calibrating the compass
A pp lies to: ve hicles w ith d ig ital compass
If the display is incorrect or inaccurate, the com­

~ Drive in a circle at about 6 mph (10 km/h) until
a dir ection is displayed in the in terior rearview
mirror.
58
A WARNING
To reduce the risk to yourself and other driv·
ers, calibrate the compass in an area where
there is no traffic.

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.

Brake booster
The brake booster amplifies the pressu re yo u ap­
p ly to the brake pedal. It only operates while the
engine is running or when the ignition is switched
on (plug-in hybrid drive*) .
A WARNING
- Only apply the brakes for the purpose of
cleaning the brake system when road and
traff ic conditions permit. You must not en­
danger other road users. This increases the
r isk of an accident .
-
-Never let the vehicle roll while the engine is
stopped because this increases the risk of an
acc ident.
- Depend ing on the veh icle equipment, the
brake pedal may be pulled downward when
the vehicle automatically initiates b rak ing.
- Never place objects in the driver's footwell.
An object could end up in the area around
the pedals and prevent you from using
them. You wo uld not be able to use the ped­
als if sudden driving or braking mane uvers
were needed, which increases the risk of an
accident.
- Only use floor mats that do not obstruct the
area around the pedals and that can be se­
curely fastened in the footwe lls.
- T o reduce the risk of injury, do not place
your foot under the brake pedal.
(Llj) Note
-Never let the brakes "rub" by pressing the
pedal lightly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking distance and
causes wear.
- Before driving on a long stretch with steep
slopes, reduce your speed and shift to the
next lower gear This makes use of the en­
gine braking effect and relieves the brakes.
If you need to brake add it ionally, brake in
i ntervals and not cont inuously.
Intelligent Technology
(D Tips
- If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit your vehicle with a front spoi l­
er, wheel covers or simi lar items, make sure
that the air flow to the front wheels is not
interrupted. Otherwise the brake system
can become too hot.
Electromechanical
steering
The electromechanical steering supports the
driver's steering movements.
Power steering adapts electronically based on
the ve hicle speed.
Indicator lights and messages
• Do not drive vehicle: steering defective
If this indicator light turns on and stays on and
th is message appears, the power steering may
have failed .
Stop the vehicle in a safe location as soon as pos­
s ible. Do
not cont inue driving. See an authorized
Audi dealer or authorized Audi Service Fac ility for
ass istance .
l;r-ij Steering: system fault! You can continue
driving
If the indicator light turns on, the steering wheel
may be more difficult to move or more sensitive
than usual. The steering whee l may also be at an
angle when driving straight.
Drive slowly to an authorized Audi dea ler or au­
thorized Audi Service Facility to have the mal­
function corrected.
