Automatic dimming rearview mirror*
• Press the button @to switch the dimming
function on the mirror on or off. If the indicator
light @ turns on, the interior and exterior mir­
rors* are dimmed when light shines on them
(for example headlights shining from a vehicle
behind you) .
A WARNING
If the glass on an automatic dimming mirror
breaks, electrolyte can leak out . This liquid
can irritate the skin, eyes and respiratory sys­
tem. If there is contact with the fluid, flush
immediately with plenty of water. Consult a
physician if necessary.
- Repeated or long-term exposure to electro­
lyte fluid can lead to irritation of the air­
ways, especially in people with asthma or
other respiratory conditions. Take deep
breaths immediately after leaving the vehi­
cle or, if this is not possible, open all of the
doors and windows as wide as possible.
- If electrolyte fluid enters the eyes, flush
them thoroughly with a large amount of
clean water for at least 15 minutes and then
seek medical attention.
- If electrolyte fluid comes into contact with
the skin, flush the affected area with clean
water for at least 15 minutes and then clean
with soap and water and seek medical at­
tention. Clean affected clothing and shoes
thoroughly before wear ing again .
- If the fluid was swallowed and the person is
conscious, flush the mouth with water for at
least 15 minutes. Do not induce vomiting
unless this is recommended by medical pro­
fessionals. Seek medical attention immedi­
ately.
(D Note

consumption to zero (fuel shut-off during decel­
eration).
Shift efficiently
An effective way to save fuel is to upshift earlier .
Staying in a gear too long uses fuel unnecessari­
ly. Press down on the accelerator pedal slowly
and avoid "kick-down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
There are benefits to stopping the engine, for ex­
ample when at railroad crossings or traffic lights
with longer red lights. Stopping the engine for
30-40 seconds already saves more fuel than the
amount of extra fuel needed to restart the en­
gine.
It takes a very long time in idle to warm the en­
gine up to operating temperature . Wear and
emissions are especially high in the warm-up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while doing this.
Have maintenance performed regularly
By having maintenance performed regularly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The maintenance condition of your vehicle not only
affects traffic safety and long-term value but al­
so impacts
fuel consumption. A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Also check the
oil level when refueling. The oil
consumption
depends largely on the engine load
and speed . It is normal for the oil consumption
of a new engine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can only be properly judged after
approximately 3,000 miles (5,000 km) have been
driven.
Driving
Fewer short trips
The engine and catalytic converter have to reach
their optimal
operating temperature to reduce
fuel consumption and noxious emissions effec­
tively.
Just after starting, a cold engine in a mid-size car
only achieves a fuel economy of 6-8 mpg
(30-40 l/100 km). After about a half a mile, fuel
economy climbs to 12 mpg (20 l/100 km). After
about 2.5 mi
(4 km), the engine is at its proper
operating temperature and fuel economy has
reached a normal level. So you can see that you
should avoid short trips whenever possible .
The
outside temperature is also critical in this re­
gard. Your car consumes more fuel in the winter
than in the summer.
@ 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 proper­
ty.
(D Note
- 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 .

Trailer towing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­my and performance.
Trailer towing not on ly places more stress on the
ve hicle, it also ca lls for more concentration from
the dr iver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross tra iler weight. The hitch must be suitab le
for your veh icle and tra iler and must be mounted
securely on the vehicle's chassis at a technically
sound
locat ion . Use on ly a trailer hitch with a re­
movable ba ll mount . Always che ck with the t rail ­
er hitch man ufac tur er to make s ure t hat you are
using the co rrect hi tc h.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system. No mod ificat ions should be
made to the vehicle exhaust and b rake systems .
Fr om t ime to t ime, che ck that all hitch mo unti ng
bol ts rem ain securely f aste ned.
W hen you are not tow ing a tra iler, remove the
tra ile r hitc h ba ll mount . This prevents the hit ch
from caus ing damage s hou ld your veh icle be
s truck from be hind ¢
,&..
Trailer brakes
If you r trailer is equipped with a brak ing system,
check to be su re that it conforms to all regula­
tions .
74
The t rai ler hydraulic bra ke system must not be
directly connected to the vehicle's hydraulic
bra ke system ¢&. .
Safety chains
Always use s afety chains be tween you r vehi cle
and t he tra ile r.
Trailer lights
Traile r lights must meet all regula tions . B e s ure
to check w ith your author ized Audi dealer for cor­
r ec t wir ing, swi tches, an d relays.
Mirrors
If you are unable to see t he traffic behind you us­
i ng t he regular outs ide mirrors, then yo u
must in­
stall ex tended mirro rs . It is impo rtant that you
al ways have clear vision to the rear.
.&_ WARNING
- If a tra ile r has e lectr ical brake s ple ase no te
t h at these b ra kes are not activated by the
factory -fit ted contro l unit -risk of accident!
- After removing the traile r h itch, d o no t
s t o re it in your vehicle. In case of sud den
braking, the hitch co uld fly forwar d and in ­
jure you or yo ur passenge rs.
- Never install a "we igh t distribu tin g" or
"loa d eq ualizing" trailer hitch on your veh i­
cle . The vehicle was not designed fo r these
kinds o f trailer hitches. The hitch attach­
ment can fail, ca us ing the tra ile r to tear

Fig. 79 Perm itted ball pos itio n of th e t rail er hitch
Trailer towing weights
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissible trailer weight is
2,200 lbs (1,000 kg) . The maximum permissible
unbraked trailer weight is 1,650 lbs (750 kg) .
These specifications apply when driving on roads having an incline of less than 12%.
Permissible tongue load
For best vehicle handling under these changed
conditions, adjust the trailer load so that the
tongue load is at the maximum allowable or
slightly lower. You can get an approximation of
the tongue load with a bathroom scale or you can
measure the load at a trucking company or
weighing station.
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissible load on the ball
hitch may not exceed 220 lbs (100 kg) .
It is rec­
ommended to use the maximum permissible
load.
Trailer load distribution Be sure the load in the trailer is held securely in
place to prevent it from shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer ¢.&.
in Driving instructions on page 76 .
Ball mount
The trailer hitch may only be used with suitable ball mount and ball¢
fig. 79. Installation of the
hitch ball must be carried out in accordance with
the manufacturer's instructions .
Trailer towing
Engine cooling system
Towing a trailer makes the engine work harder. It
is important that the cooling system's perform­
ance 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 tire pressure listed under "Full
load" on the tire pressure label
¢page 181. In­
flate trailer tires to trailer and tire manufactur­
ers' specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle .
Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains should cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
· Driving instructions
Driving with a trailer always requires extra care
ond consideration.
Weight distribution
Towing a loaded trailer with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced " rig is easier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keeping the trailer as light as possible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while observing tongue load require-
ments and vehicle loading considerations. .,.
