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 ..,_

C) C0 ....
"' " "' .... 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,
t rip length, etc.

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
the steering wheel rim or on the steering
wheel hub . Holding the steering wheel the
wrong way can cause serious injuries to the hands, arms and head if the driver's airbag
deploys.

open the driver's door. The locked steering helps
prevent vehicle theft.
Emergency off function
If it is absolutely necessary, the engine can also
be turned off while driving in the R, Dor S selec­
tor lever position at speeds below 6 mph (10 km/
h). To stop the engine, press and hold the
I START ENGINE STOPI button and also press the
brake pedal.
& WARNING
-Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­
ous injuries .
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Driving
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the 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.
(D Tips
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 already warm
and the engine compartment is also heated
by the sun's rays.

& WARNING
-
-Do not press the acce lerator peda l inadver­
tently if a gear is selected when the vehicle
is stationary and the engine is running. Oth­
erwise, the vehicle will start to move imme­
diately and this could result in an accide nt.
- Eme rgency braking should only be used in
an emergency, when the normal brake pedal
has failed or the brake pedal is obstructed . ..,.
81

Driving
During emergency braking, your vehicle will
brake similar to heavy braking. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics. In cor­
ners and when road or weather conditions
are bad, a full brake application can cause
the vehicle to skid or the rear end to swerve,
which increases the risk of an accident.
- If the power supply fails, you cannot set the
parking brake if it is released. In this case,
park the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- Always take the vehicle key with you when leaving your vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle . Otherwise chil­
dren could start the engine, release the
parking brake or operate electrical equip­
ment such as power windows, which in­
creases the risk of an accident.
- No one should remain in the vehicle when it is locked -especially children. Locked doors
make it more difficult for emergency work­
ers to get into the vehicle, which puts lives
at risk.
(D Tips
When stopping at a traffic signal or stopping in city traffic, you can set the parking brake
manually. The vehicle does not have to be
held with the brake pedal. The parking brake
eliminates the tendency to creep when a se­
lector lever position is engaged. As soon as
you press the accelerator pedal, the parking brake releases automatically and your vehicle
starts to move
c> page 82.
(D} Tips
-Occasional noises when the parking brake is
set and released are normal and are not a
cause for concern.
- The parking brake goes through a self-test
cycle at regular intervals when the vehicle is
stopped. Any noises associated with this are normal.
82
- If there is a power failure, the parking brake
will not set if it is released, and it will not release if it is set ¢&. . See an authorized
Audi dealer or authorized Audi Service Fa­ cility for assistance .
