Braking
What affects braking efficiency?
New brake pads
D ur ing the first 250 miles (400 km) , new brake
pads do not possess their full b raking effe ct, they
have to be "b roken in" first ¢,&. . You can com­
pensa te for th is slightly reduced b raking power
by p ushing harder on the brake pedal. Avo id
heavy braking loads dur ing the break-in period .
Operating conditions and driving habits
The brakes on today's automobi les are s till sub­
je ct to wear, depending large ly on operating con­
dit ions and driving habits ¢.&. . On vehi cles that
a re either driven mostly i n stop-and-go city traf­
fic or are drive n hard, the b rake pads sho uld be
checked by your authorized A udi dealer more of­
ten than specified in the
Wa rrant y & Mainte ­
nance book let .
Failure to have your brake pads
i nspected can result in reduced brake perform ­
ance .
On steep slopes, you should use the brak ing ef­
fect of the engine . Th is way, you prevent unnec­
essary wear on the brake system . If you must use
your brakes, do not ho ld the bra kes down contin­
u ously. P ump the bra kes at inte rvals.

Driving and th e en vironm ent
(D Tips
- Check the depth of the water before driving
through it .
- Do not stop the veh icle, drive in reverse or
switch the engine
off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your veh icle to drive
through safely.
- Avoid driving through salt water because it
can cause corrosion.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­ erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline ¢ page 186,
Fuel supply .
~ Never run the tank down a ll the way to empty .
~ Never put too much motor oil in your engine
¢ page 195, 9::?1 Adding engine oil .
~ Never try to push- or tow-start you r vehicle.
The cata lytic converter is an efficient "clean-up"
dev ice bu ilt into the exha ust system of the vehi­
cle. The cata lytic conve rter burns many of the
pollutants in the exhaust gas before they are re ­
leased into the atmosphere.
The exclusive use of unleaded fue l is critica lly im­
portant for the life of the catalytic conve rter and
p roper functioning of the engine.
A WARNING ,..____ -
- The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust tail pipes once they
have become hot. This could result in burns.
- Do not park or ope rate t he vehicle in areas
where the hot exha ust system may come in
contact with dry grass, br ush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani-
178
fold, exha ust pipes, cata lytic conve rter or
heat shields. D uring driving, the substance
used for undercoat ing could overheat and
cause a f ire.
Cl) Note
- Be aware that just one tank f illing wit h
leaded fu e l w ill already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil leve l
¢page 195.
-Do not drive until the fue l tank becomes
completely empty. The engine could mis­
fire. Unbu rned fue l cou ld also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not turn off the ign ition while the vehicle
is moving .
- Do not continue to operate your vehicle un­
der these conditions, as otherw ise fuel can
reac h the catalytic converter. T his could re­
sult in overheat ing of the converter, requir­
ing its replacement.
- T o ass ure eff icient operat ion of the Emis­
sion Contro l System:
- Have you r vehicle maintained properly and
i n accordance wit h the service recommen­
dations in your Warranty
& Ma intenance
booklet.
- Lack of proper ma intenance as well as im­
p roper use of the veh icle will impa ir the
function of the emission control system
and could lead to damage.
(® For the sake of the environment
Even when the Emiss ion Control System is op­
erating properly, t he exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. Th is depends on the sulfur
content of the fuel being used. Us ing a d iffer­
ent brand of fuel may help, or fi lli ng the tank
wi th lead-free super g rade gasoline.

0 I­co .... .... Trailer mode 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, econo­ my and performance.
T railer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For 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 trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the vehicle's chassis at a technically
sound
location . Use only a trailer hitch with a re­
movable ball mount . Always check with the trail­
er hitch manufacturer to make sure that you are
using the correct hitch.
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 modifications should be
made to the vehicle exhaust and brake systems .
From time to time, check that all hitch mounting
bo lts remain securely fastened.
When you are not towing a trailer,
remove the
tra iler hitch ball mount . This prevents the hitch
from causing damage should your vehicle be
struck from beh ind ¢
,&. .
Trailer brakes
If your trailer is equipped with a braking system,
check to be sure that it conforms to all regula­
tions .
Trailer mode
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system ¢.&. .
Safety chains
Always use safety chains between your vehicle
and the trailer.
Trailer lights
T ra iler lights must meet all regulations . Be sure
to check with your author ized Audi dealer for cor­
rect wiring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors. It is important that you
always have clear vision to the rear.
,8. WARNING
-If a trailer has electrical brakes please note
that these brakes are not activated by the
factory-fitted control unit -risk of accident!
- After removing the trailer hitch, do not store it in your vehicle. In case of sudden
braking, the hitch could fly forward and in­
jure you or your passengers.
Operating instructions
Maximum trailer weight
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
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 182.
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. .,..
181

Trailer mode
Tire pressure
When towing a trailer, inflate the tires of you r
veh icle to the cold tire pressure listed under "Fu ll
load" on the label located on the driver's side B ­
pillar (visib le when the door is open) . Inflate
trai ler tires to trailer and tire manufacturers'
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 sur e trailer safety chains are properly connect­
ed from the trai ler 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 w ill not drag on the road when you are
driving.
The chains shou ld 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
and consideration.
To obtain the best possible handling of vehicle
and trailer, please note the fo llowing :
.. Do not tow a loaded trailer when your car itself
is not load ed .
.. Be especia lly carefu l when passing other
vehicles .
.. 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 with an empty car resu lts
in a high ly unstable distribution of weight. If this
cannot be avo ided, drive at very low speeds only
to avoid the risk of losing steering control.
182
A "balanced" rig is easier to operate and control.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, wh ile
keeping the trailer as light as poss ible under the
c ir cumstances . Whenever possible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle load ing considerations .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the r ig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
cond it ion s are unfavorab le -particularly when
go ing downh ill.
Reduce vehicle speed
immediately if the trailer
shows the slightest sign of sway ing .
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing tra ilers are lower than for regular
vehicles.
Always apply brakes early. When driving down­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle . Use of the
brakes alone can cause them to overheat and fail.
Coolant tempe rature
The coolant temperature gauge c::> page 10 must
be observed carefully.
If the needle moves close
to the upper end of the scale, reduce speed im­
med iately and/or turn off the a ir cond itioner .
If the coolant temperature warning light . in
the instrument cluster starts flashing, pull off
the road, stop and let the engine
idle for about
two m inutes to prevent heat build-up .
A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.
