What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
Controls and equip­
ment Safety first Vehicle operation
become a
hazard to everyone else on the road ~& .There ­
fore:
- Do not let yourself be distracted by passengers or by
using a cellular telephone.
- NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.I.
- Observe all traffic laws, rules of the road and speed limits
and plain common sense.
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed.
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •

The warning light~ in the instrument cluster lights up when the
ignition is switched on as a reminder to fasten the safety belts. In
addition, you will hear a warning sound.
After the ignition is switched on, the warning tone will come on for about 6 seconds a long w ith a-~ warning light in the instru ment
cluster if the driver has not fastened his safety belt . As soon as the
driver has fastened his safety belt, the warning tone will stop and
the warning light will go out .
I f the driver has not buckled -up within about 24 seconds after the
warn ing tone has stopped, the warn ing tone will sound again for
about 6 seconds. The warning tone will sound repeated ly for about
6 seconds at 24 second intervals unti l the driver has buckled-up . The
safety belt warning system is active for about 5 minutes and during
this time the wa rning light in the instrument c luster will stay on.

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create ve ry strong forces for pe ople ri ding
in vehicles.

The physica l principles are simple. Both the vehicle and the passen­
gers possess energy which varies with vehicle speed and body
we ight . Engineers call this energy "kinetic energy ."
The higher the speed of the vehicle and the greater the vehicle's
we ight, the mo re energy that has to be "absorbed" in the crash .
Vehicle speed is the most significant factor. If the speed doub les
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times!

conditions permit .•
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle.
- Do not warm up the vehicle by letting the engine run at
idle.
It makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at rai lroad crossings, or at traffic lights that have
long waits on red. Turning the engine off for just 30 -40 seconds
saves more fuel than is burned s tarting the engine again .
It takes a long time for the engine to warm up fully when it is
running at idle. However, wear and noxious emissions are especially
high when the engine is warming up. So you should drive away as
soon as you star t the engine and avoid running at high rpms while
the engine is still warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would
go unheeded. Extended id ling also produces heat, which could
resu lt in overheating or other damage to the veh icle or other
property .•
Regu1ar maintenance
A badly tuned engine unnecessarily wastes a lo t of fuel.
- Have your ve hicle serviced at regular intervals . By having your vehicle regularly serviced by an Audi dealer helps to
ensure that it runs properly and economical
ly . The condit ion of yo ur
vehic le not only affects its safety and abi lity to hold its va lue, it also
affects
fuel consumpt ion .
C heck your oil each time you fill your tank .
The amount of oil used is related to engine load and speed.
I t is norma l for the oil consumption of a new engine to reach its
lowest va lue after a certain mi leage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) be fore you can properly assess oil consumption .
This also applies to fuel consumption and engine output .

• Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet. Lack of proper maintenance as well as improper use of the
vehic le wi ll impai r the function of the em ission control system and
cou ld lead to damage.
• Do no t alter or re move any component of the Emiss ion Contro l
System unless approved by the manufacturer.
• Do not alte r or remove any device, such as heat shields,
switches, ignition wires, valves, which are designed to protect your
vehic le's Emission Control System and other important veh icle
components. •

-Cleaning and protection P':ft':I _______________ _
& WARNING
• Do not clean the underside of the chassis, fenders, wheel
covers, or other hard to reach parts without protecting your hands
and arms. You may cut yourself on sharp-edged metal parts.
• Always read and heed all WARNINGS and other information
~ page 230.
0 Note
• Never try to remove dirt, mud or dust if the surface of the vehicle
is dry. Never use a dry cloth or sponge, since this could scratch your
vehicle's paint or windows.
• Never wash your car in bright sunlight. Drops of water act as
magnifying lenses and may damage your paint .
• When you wash your car in the winter: if you rinse your vehicle
with a hose, be careful not to aim the stream of water directly at
locks, or at door or hatch openings - they can freeze shut.
• Never use sponges designed to remove insects, or any kitchen
scouring sponges or similar products. They can damage your paint
finish .
• Never use a dry cloth or sponge to clean the headlights. Only use
wet cloths or sponges to prevent scratches . It is best to use soapy
water.
<£> For the sake of the environment
In the interest of the environment, the vehicle should only be
washed in special wash bays. •
Washing your vehicle with a power washer
Cleaning the exterior of your car with a high-pressure
power washer is safe as long as you observe a few simple
rules.
- Before using the power washer, make sure you have read
and understood the WARNINGS~
& in "General infor­
mation" on
page 230.
Always follow the operating instructions for the power
washer.
Make sure that the jet on the spray hose produces a "fan
shaped spray".
Do
not hold the spray nozzle too close to soft materials.
When cleaning the vehicle with a power washer always follow the
operating instructions. This applies particularly to the
operating
pressure and the spraying distance. Maintain a sufficient distance
to soft materials such as rubber hoses and sound/vibration dead­ ening materials {particularly on the underside of the engine hood).
Do not use a jet which sprays water in a
direct stream or one that
has a
rotating jet.
Water temperature should not exceed 140
°F (60 °C).
& WARNING
Never wash tires with a jet that sprays water in a direct stream.
This could cause invisible damage to the tires and weaken them,
even if the spray is from a relatively long distance and for a short
time . Damaged and weakened tires can fail and cause accidents
and personal injury.
0 Note
• Never use a power washer to clean the power top itself.
