bumper: Position of
radar sensors (not
visible on outside)
Fig. 139 Signal light
on the outside mirror -
driver's side
Side ass ist uses radar sensors (not visible on outside)=> fig. 138 to
help the driver check blind spots, and see what is happening in traffic
behind the vehicle=>
page 137, fig. 141.
Signal lights are bu ilt into both outside mirrors
(D => fig. 139 . The
signal light on the left ou tside mirror assists when moving over into the
left lane and the signal light on the right outside mirror assists
when moving over into the right lane.
Th e sig nal light comes on to tell you that side assist has detected a
vehicle on that side and that the position of this other vehicle should
be taken into account if you were to change lanes. Thi s is called the
informational stage signal =>
page 138. The informationa l stage
signal is designed so that you not ice it only when you are looking in
the outside m irror.
When you activate the turn s ignal and side assist detects a vehicle in
a notable location, the correspo nding signal on the outside mirror
flashes briefly and brightly several times. This is the alert stage
signal =>

Driving Safely ---------------------"~'----
Important things to do before driving
Safety is everybody's job! Vehicle and occupant safety
always depends on the informed and careful driver.
For your safety and the safety of your passengers, before
driving always:
- Make sure that all lights and signals are operating
correctly.
- Make sure that the tire pressure is correct.
- Make sure that all windows are clean and afford good visi-
bility to the outside.
- Secure all luggage and other items carefully::::>
page 86.
-Make sure that nothing can interfere with the pedals.
- Adjust front seat, head restraint and mirrors correctly for your height .
- Instruct passengers to adjust the head restraints according to their height.
- Make sure to use the right child restraint correctly to
protect children ::::,
page 222, "Child Safety".
- Sit properly in your seat and make sure that your passen­ gers do the same::::,
page 77, "General recommenda­
tions".
- Fasten your safety belt and wear it properly. Also instruct
your passengers to fasten their safety belts properly

ment Safety first Vehicle operation
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
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.).
- 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.•
Vehicle care Do-it-yourself service Technical data

-Make sure that your passengers also buck le up and prop ­
erly wear the ir safety belts .
- Protect your children with a child restraint system appro-
priat e for the si ze and age of the child ren.
The warn ing light tin the instrument cluster lights up when the igni­
tion is switched on as a reminder to fasten the safety belts. In addi­
tion, you wi ll hear a war ning sound.
After the ignition is switched on, the warning tone will come on for abou t 6 seconds along with a t warn ing light in the inst rument
cluster if e ither the driver or (on USA models o nly) front seat
passenge r has not fastened their safety bel t. As soon as the driver
and front seat passenger have fastened the safety belt, the warning
tone will stop and the warning light will go out.
If both the driver and front seat passenger have not buckled- up
within about 24 seconds after the warning tone has stopped, the
wa rning tone w ill sound aga in for about 6 seconds. The warn ing tone
w ill sound repeatedly for about 6 seconds at 24 second interva ls unt il
bo th the driver and fron t passenger have bu ckled -up. The safety belt
warning system is active for about 5 minutes and during this time the
warning light in the instrument cluster wi ll stay on.
Fasten your safety b elt now and make sure that your pa ssengers
also properly put on their safety belt s. •

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for people
riding in vehicles .

Th e physical pr incip les are simple. Bot h the vehicle and the passen­
gers possess energy which varies with vehicle speed and body weight.
Enginee rs call th is energy "kine tic en ergy ."
The higher the speed of the vehicle and the greater the veh icle's
weight, the more 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 SO km/h), the energy increases 4 times!

[I) Tip s
The consumption estimates as published by ENV IRONMEN TA L
PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, wh ich w ill vary
depending upon vehicle load and speed, road and weather conditions ,
trip length, etc. •
Drive smoothly :1nd keep a Lookout ahead
Vehicles use the most fuel when they are accelerating .
-Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they a re accelerating. If you antici­
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible -for
example when you see that the next traffic l ight is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed .
Accelerating gently reduces fuel consumption, engine wear, and does
not disturb the environment .
Fuel consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approx imately three
quarters of top speed, fuel consumption will be reduced by one half.
Never dr ive faster t han the posted speed limit and weather condi­
tions permit. •
Controls and equip­
ment Safety first Vehicle operation
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
-
Shut the engine off when you are not driving the vehicle .
- Do not warm up the veh icle by letting the engine run at
idle.
It makes sense to shut off the engine in traffic jams, when wa iting for
trains to pass at railroad crossings, or at traffic lights that have long
wa its on red . Turn ing the engine off for just 30-40 seco nds saves
mor e fuel than is burned starting the engine again .
It takes a long t ime for the engine to wa rm up fully when it is run ning
at idle. However, wear and noxious emissions are espec ia lly high
when the eng ine is wa rming up. So you should dr ive away as soon as
you start the engine and avoid running at hig h rpms while the engine
is still warm ing 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 idling also produces heat, which could result in
overheat ing or other damage to the vehicle or othe r property.
Regular mai n _t_ e_ n_a_ n_ c_e ___________ _
A badly tuned engine unnecessarily wastes a lot of fuel.
-Have your vehicle serviced at regular intervals .
By having you r vehicle regularly serviced by an authorized Audi dealer
helps to ensure that it runs properly and economically . The condit ion
of your vehicle not only affects its safety and ability to ho ld its val ue,
it also affects
fu el con sumpt ion.

Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor ­
tation.
If yo u plan to tow a t rai ler, p lease rem emb er that the add itiona l load
wi ll affect durab ility, economy and performance.
T railer tow ing not on ly p laces mo re s tress on the vehicle, it a lso calls
for more concentrat ion from the driver.
For this reason, a lways follow the ope rating and dr iv ing instr uctions
prov ided and use common sense .
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the gross trailer weig ht.
Th e hitch mus t be suitable for yo ur vehicle a nd tra ile r and mus t be
mounted secure ly on the vehicle's chassis at a
technically sound l oca­
t ion. Use only a trailer hitch wi th a remov ab le b all m ount. Alw ays
check w ith the tra iler hitch manufacturer to make sure that you are
using t he cor re ct hi tch.
Do not use a bumper hitch.
The h itch must be installed in such a way t hat it does not interfere
w ith the impa ct-absorbing b umper system. No mod ifi cat ions sho uld
be made to the vehicle exhaust and brake systems. From time to
ti me, chec k tha t all hitc h mou ntin g bol ts rem ain secure ly f aste n ed.
When you a re not tow ing a tra iler, remove the tra iler hitch ba ll
mount. This prevents the hitc h from caus ing damage should yo ur
vehicle be struck from behind=> &.
Controls and equip­
ment Safety first Vehicle operation
Trailer brakes
If your trailer is eq
uipped with a braking system, check to be s ure that
i t confo rm s to all regula tions.
The tra iler hydraulic brake system must not be directly connected to
the vehicle's hydraulic brake system=>& .
Safety chains
Alw ays use safety chains be twee n your vehicle and the trai ler.
Trailer lights
Tr ailer l ights m ust meet all reg ulat io ns. Be su re to check with your
author ized Audi deale r for correct wir ing, switches, and re lays.
Mirrors
If you are unab le to see the traffic behind you us ing the regular
outside m irro rs, then you
must install extended m irro rs. It is impor­
tant that yo u
always have clear vision to the rear.
& WARNING
• If a trailer has electrical b rake s please note that these brakes
are not activated by the factory-fitted control unit -ri sk of acci­
dent!
• After removing the trailer hitch , do not store it in your vehicle.
In case of sudden braking, the hitch could fly fo rward and injure
you or your passengers. •
Operating instructions
Maximum trailer we ight
A trailer for your vehicle is limited to a typical class 1 or class 2 trailer . .,.

Trailer load distribution
Be sure the load in the trailer is held securely in pla ce to prevent it
from shifting forward, backward or s ideways.
Never allow a passenger to ride in a trailer => & in "Driving instruc­
tions" on
page 256.
Engine cooling system
Towing a trailer makes the eng ine work harde r. It is important that
the cooling system's performance is up to the additional load. Make
sure that the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the label located either on the
dr iver's side B-pillar (visible when the door is open) or inside the fuel
filler flap . Inflate trailer tires to trailer and tire manufacturers' spec­
ifications.
Lights
The headl ight settings should be checked w ith the trailer attached
before driving off. Check to make sure both vehicle and trai ler lights
are working properly.
Safety chains
Be sure trailer safety cha ins are properly connected from the trailer
to the hitch on the vehicle. Leave enough s lack in the chains to permit
turning corners. When you install safety chains, make sure they will
not drag on the road when you are driving.
T he chains should cross under the trailer tongue to p revent it from
dropping in case of separation from the hitch.
Driving instruct!ons
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the following:
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especially careful when passing other veh icles .
- Observe speed limits.
- Do not drive at the maximum permissible speed.
- Always apply brakes early.
- Monitor the temperature gauge .
Weight distribution
Towing a loaded trailer w ith an empty car results in a highly unstable
distr ibution of weight. If this cannot be avoided, drive at very low
speeds only to avo id the r isk of losing steer ing control.
A "balanced" rig is easier to operate and control. Th is means that the
tow vehicle should be loaded to the extent possible and permissible,
wh ile keeping the trailer as light as possible under the c ircumstances.
Whenever possible, trans fer some cargo to the luggage compart ­
ment of the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
Th e higher the speed, the more difficult it becomes for the driver to
control the r ig . Do not drive at the maximum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icularly when go ing downhill.
Reduce vehicle speed
immediately i f the trailer shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating. _,
