purposes:
Spee d warn ing 1 lDl/lOl ( Canada models )
You can use speed warning 1 to set the maxi
m um speed w hile you are driv ing. This sett ing
will remain in effe ct until you turn off the igni
tion, assuming that you have not changed or reset the setting .
The speed warning symbo l
(alllDl (Canada
models) in the warning 1 display appea rs
when you exceed the maxim um speed. It goes
out when the speed falls be low the stored
maximum speed.
The speed wa rning symbo l w ill also go out if
the speed
exceeds the stored maximum speed
by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed
is deleted.

Speed warning 2 lCl/EOl (Canada m odels )
Storing warning 2 is recommended if you al
ways
want to be remi nded of a certa in speed,
for example when you a re traveling i n a cou n
try that has a general maximum speed limit,
or if you do not want to exceed a specified
speed for winter tires.
The speed wa rning 2 symbol,

7 4 On the road
Cruise control
Introduction
The cruise control system keeps the speed
constant.
The cruise control system makes it possible to
drive at a constant speed over 20 mph (US
model) or 30 km/h (Canadian model) . This is
true only to the extent that engine power or
engine braking effect allow . Using the system
takes the strain off the "gas pedal foot" - es
pecially on long trips.
In the control mode, the indicator light in the
instrument cluster is lit
aijj(1)~1~ (US model);II
(Canadian model).
The cruise control system automatically
switches itself off immediately under the fol
lowing conditions:
- Pressing the brake pedal.
- Pressing the clutch pedal.
A WARNING
-Always pay attention to traffic even when
the cruise control system is switched on.
You are always responsible for your speed and the distance between your ve
hicle and other vehicles.
- For safety reasons, the cruise control sys
tem should not be used in the city, in
stop-and-go traffic, on twisting roads
and when road conditions are poor (such
as ice, fog, gravel, heavy rain and hydro
planing) -risk of accident.
- Turn off the cruise control system tem
porarily when entering turn lanes, high
way exit lanes or in construction zones.
- Please note that inadvertently "resting"
your foot on the accelerator pedal causes
the cruise control system not to brake.
This is because the cruise control system
is overridden by the driver's acceleration.
(D Note
On manual transmission vehicles: If you
shift into neutral with the cruise control system switched on, always depress the
clutch
pedal! Otherwise the engine will
race and could be damaged as a result.
(D Tips
When driving on steep downward grades,
the cruise control system cannot keep the
speed constant. The vehicle's own weight increases the speed. Shift into a lower gear
in plenty of time or brake the vehicle with
the foot brake.
Saving the speed
The desired speed must be saved.

Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapte r exp lains why safety be lts a re nec
essary, how they work and how to adjust and
wear them correctly.
~ Read all the information that fo llows and
heed all of the inst ruct ions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of ser ious
personal in jury and death .
- Safety belts are the sing le most effective
means availab le to red uce the r isk of se
rious injury and death in a utomob ile acci
de nts . For your prot ecti on and that of
yo ur passenge rs, always co rrec tly wear
sa fe ty bel ts when the ve hicle is mov ing.
- P re g nant women, injured, or physically
imp aired perso ns must also use safe ty
belts. L ike a ll vehicle occup ants, they are
more like ly to be ser ious ly injure d if they
do not wea r safety be lts . The best way to
protect a fet us is to protect the mother -
thro ughout the entire pregnancy.
Number of seats
Your Audi R8 has two seating posit ions in the
front. Each seating position has a safety belt.
A WARNING
Not wearing safety belts or wearing them
im proper ly increases the risk of ser ious
personal in ju ry and death.
- Never st rap more than one person, in
clu ding small ch ild ren, into any belt. It is
especially dangerous to place a safety
belt over a child s itting on yo ur lap.
- Never let mo re people ride in t he ve hicle
t h an t he re are safety be lts ava ilable.

4 Safety belt warning light
Your vehicle has a warning system for the
driver and front seat passenger to remind you
about the importance of buckling up .

- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lling
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the

Advanced Airbag System components
The fron t passenger sea t in your vehicle h as a
lot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sensing mat, sensors, wiring, brack
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ignit ion is on.
The control unit mon itors the Advanced Air
bag System and turns the airbag indicator
l ight on when a ma lfunction in t he system
components is detected. The func tion of the
a ir bag ind icator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad
vanced A irbag System, you m ust take care to
prevent it from be ing damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air
bag System abou t the seve rity of the crash.
- An electron ic co ntrol unit, with integ rated
crash sensors for front and side impacts .
T he cont ro l unit "dec ides " w het her to fire
the front airbags based on the information
received from the crash senso rs . The contro l
unit a lso "decides" whethe r the safety be lt
pretensioners should be activated . -
An Advanced A irbag w ith gas generator for
the driver inside the steering w heel hub.
- An Advanced A irbag w ith gas generato r in
side the inst rument panel for the front pas
senger.
- A we ight -sensing mat unde r th e upho ls tery
pa dding of the front passenger seat cushion
that measures the total weight on the seat .
The informat ion registered is sent continu
ously to the electronic control unit to regu late deployment of the front Advanced Air
bag on the passenger side .

- The PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instru
ment panel
c::> page 120, fig. 123 and tells
you when the front Advanced Airbag on the passe nger side has been tu rned off.
- A senso r below the safety be lt latch fo r the
front seat passenger to measure the tension on t he safety be lt. The tension on the safety
be lt a nd the weight regis tered by the

D amage to the fron t passenger seat can
p revent the fro nt airbag from wor king
properly.
- I mp roper repai r or d isassembly of the
front passenge r and dr ive r sea t will pre
vent the Advanced Air bag System from
