194 Driving and en vironm ent
8_ WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full braking effect.
CD Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
-
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in on environmentally sound manner.
,,. Always use lead-free gasoli ne¢ page 211,
Fuel supply .
,,. Never run the tank down a ll the way to
empty.
,,. Never put too much motor oil in your en-
gine ¢
page 221, "t':::r. Adding engine oil.
,,. Never t ry to push- o r tow-start your veh icle.
The catalytic converter is an effic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the polluta nts in the exhaust gas be­
fore they are released into the atmosphe re. The exclusive
use of unleaded f uel is critica lly
important for the life of the catalytic convert­
er and proper funct ion ing of the eng ine .
A WARNING
= -
-Do not park or operate the vehicle in
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fuel spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ver ter or heat shields. Dur ing driv ing, the
substance used for under coa ting co uld
overhea t and cause a fire.
CD Note
- Be aware that just o ne tank filling with
leaded fu el w ill already ser io usly de ­
gr ad e the per form ance o f the catalytic
c onverte r.
- Do not ex ceed t he corre ct engine oil level
r:;!) page 2 21.
- Do not drive until the fuel tank be co m es
completely emp ty. The engine co uld mis­
fire . Unburned fuel could also get in to
the exhaust system and this co uld cause
the cata lytic converter to overheat .
- Do not turn off the igni tion whi le the ve ­
hicle is mov ing.
- Do not contin ue to ope rate your veh icle
unde r these conditions, as otherwise fuel
can reach the catalyt ic converte r. T his
co uld resu lt in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave you r vehicle maintained p rope rly
and in accordance w ith the se rvi ce rec ­
ommen dat ions in yo ur Warranty &
M ain tenance boo klet.
- L ack of prope r maintenan ce as we ll as
i mprope r use of t he ve hicl e wi ll impair
the func tion of the em ission cont ro l
system and could lea d to damage .

@ For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fuel being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, environmental impact, and
wear on you r engine, bra kes and t ires largely
depend on th ree factors:
= your persona l dr iving style
- operating conditions
- technica l lim itations
I f you anticipate what yo u need to do next and
drive economically, you can easi ly cut your
fuel consumption by 10-15 percent. This sec­
tion will give you some t ips on how you can
he lp the environment and your pocketbook.
@ Tips
The consumpt ion estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, wh ich will vary depending upon vehi­
cle load and speed, road and weather con­
ditions, tr ip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
" Avoid unnecessary accele rat ing and braking.
Dri vin g and en vironm ent 195
Vehicles use the most fue l when they a re ac ­
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
th us, acce lerate less. Let the vehicle coast
whenever possible -for example when you see
that the next traff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
" Try and keep well below your car's maxi-
mum speed.
Acce lerating gently red uces fue l cons ump­
tion, engine wear, and does not disturb the environment.
Fuel consumpt ion, exhaust emiss ions and en ­
gine noise increase disproportionately at high
speeds . If you drive at approximately th ree
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions perm it.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
" Shut the eng ine off when you are not driv­
ing the vehicle.
" Do not warm up the ve hicle by letting the
eng ine run at idle .
It makes sense to shut off the engine in traffic
jams, when wa it ing for tra ins to pass at rail­
road crossings, or at traffic lig hts t hat have
long waits on red . T ur ning the eng ine off for
just 30-40 seconds saves mo re fuel than is
bur ned star ting the e ngine again.
It takes a long t ime for the engine to warm up
fully when it is run ning at idle . However, wea r
and noxious emissions are espec ia lly high
whe n the eng ine is wa rm ing up. So yo u shou ld
drive away as soon a s you start the e ngine and
avo id r unning at high rpms whi le the engine is
still warming up.

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb­
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys­
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
trai le r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from be hind
¢ &. .
Trailer brakes
If yo ur tra iler is equ ipped w it h a braking sys­
tem, check to be su re that it conforms to a ll
r eg ulat io ns.
Trailer towin g 197
The trailer hyd ra ulic bra ke system must not be
direct ly connected to the vehicle's hydraulic
brake system
¢ &. .
Safety chains
Alw ays use s afety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r lights m ust meet all reg ulations . Be
su re to check w ith your authorized Audi dealer
fo r c orrec t w iri ng, sw itches, and relays.
Mirrors
If you a re unable to see the traffic behind you
u sing the regula r outside m irrors, then you
must insta ll ext ended mir ro rs. It is important
t h at you
always have clea r vis io n to the rear .
.8, WARNING
- If a trai ler has elec trica l br ake s plea se
no te th at t hese bra kes are not activat ed
by the fa ctory -fit ted control unit -risk of
accident!
- After removing the t railer hi tch, do no t
s to re it in yo ur vehicle . In case of sudden
brak ing, the hitch could fly fo rward and
in ju re you or yo ur passenge rs .
Operating instructions
Maximum traile r we ight
-
A trai ler fo r you r vehicle is limited to a typical
class 1 or class 2 tra iler.
Trailer load distribution
B e sure the lo ad in the tra iler is h eld secure ly
i n p lace to p reven t it from shifting fo rward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢ &. in Driving instru ctions on page 198.
Engine cooling system
T owing a t railer ma kes t he engine wor k hard ­
er . It is impo rta nt that the cooling system's
perfo rman ce is up to the additional load.
Make sure tha t the coo ling sys tem h as enough

198 Trailer towing
Tire pre ss ure
When towing a trai le r, inflate the t ires of your
vehicle to the co ld tire pressure listed under
"Full load" on the label located on the driver 's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac ­
turers' specifications.
Light s
The headlight settings should be checked with
the trailer attached before dr iving off. Check
to make sure both vehicle and tra iler lights
are working properly.
Saf ety chains
Be sure tra iler sa fe ty cha ins a re p roperly con­
nected from the trailer to the hitch on the ve ­
hicle. Leave eno ugh slack in the chains to per ­
mit turning corners. When you install safety
cha ins, make sure they w ill not drag on the
road when you are driving.
The chains shou ld cross under the trai ler
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 o f vehicle
and trai ler, p lease note the following:
.,. Do not tow a loaded tra iler whe n your car it ­
self is no t loaded .
.,. Be especia lly careful when passing other
vehicles .
.,. Observe speed limits .
.,. Do not drive at the maximum permissible
speed.
.,. Always apply brakes early .
.,. Monitor the temperature gauge.
Weigh t di stribution
Towing a loaded trai ler with an empty car re­
sults in a highly unstable distribution of
weight . If this cannot be avo ided, drive at very
low speeds only to avoid the risk of losing
steer ing control. A "ba
lanced' ' rig is easier to operate and con­
trol. This means that the tow vehicle should be loaded to the extent possible and permissi­
ble, while keep ing the trai ler as light as possi­
ble under the c ircumstances. Whenever poss i­
ble, transfer some cargo to the luggage com ­
partment of the tow veh icle while obse rving
tongue load requ irements and vehicle load ing
considerations.
Speed
The higher the speed, the more d iff icu lt it be­
comes for the driver to control the rig. Do not
drive at t he maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -pa rtic ularly
whe n going downhill.
Reduce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing.
Do n ot
try to sto p th e swaying by acc elerating .
Observe speed limits. In some areas, speeds
fo r vehicles tow ing tra ile rs a re lower than for
regular veh icles .
Always apply brakes early. When driving downh ill, shift into a lower gear to use the en ­
gine braking effect to slow the vehicle . U se of
the brakes alone can cause them to overheat
and fail.
Coolant tempe rature
The coo lant temperature gauge c> page 10
must be observed carefu lly. If the needle
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warning light •
i n t he i nstrument cluster starts flashing, pull
off the road, stop and let the engine
idle for
abo ut two min utes to prevent he at build-up .
_& WARNING
Anyone not proper ly restra ined in a mov ­
i ng vehicle is a t a much greater risk in an
accident . Never let anyone ride in yo ur car
who is not p roperly wea ring the rest raints
prov ided by Audi.

Trailer towing tips
Important to know
Your vehicle hand les different ly when tow ing
a trailer because o f the addit ional weight and
d iffe ren t weight distribution . Safety, perform ­
ance and economy w ill greatly depend on how
caref ully you load your trailer and operate
your rig.
B efore you actua lly tow your trailer, pr actice
turning, stopp ing and bac king up in an area
away from traffic. Keep practicing until you have become comp lete ly fam iliar with the way
your veh icle-trailer comb ination behaves and
responds.
Backing up is d ifficu lt a nd requires practice .
Backing up with a tra iler genera lly requires
steer ing action opposite to that when backing
up your vehicle without a trailer.
M aintain a g reater distance betwee n your ve­
h icle and the one in front o f you . You will need
mo re room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius .
W hen pass ing, remember that yo u cannot ac ­
celerate as fast as yo u normally wo uld be­
cause of the added load. Ma ke s ure you have
e nough room to pass . After passing , allow
p lenty o f room fo r your tra iler before chang­
in g la nes aga in .
Avoid jerky starts, sharp turns or rap id lane
changes.
(D Tips
- Do not tow a tra iler during the break-in
period of you r vehicle.
- If you tow a trailer, your A udi may re­
quire more frequent maintenance due to
the extra load

Parking on a slope
Do not park on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­ lowing:
When parking:
.. App ly the foot brake.
.. Have someone p lace chocks under both the
veh icle and the tra iler wheels .
.,. With chocks in place, slowly release t he
bra kes unt il t he whee l chocks absorb the
load .
.. Tur n the whee ls towa rds t he curb .
.,. App ly the parking brake.
.. Place an a utomat ic t ransm ission* in P, re ­
spectively a manual transmission in first or
reverse gear.
When restarting after parking:
.. App ly the foot br ake .
.. Sta rt t he engine.
.. Move the se lector lever to D/S, respectively
a man ual transmiss ion in first gear .
.. Release the parking brake and s low ly pull
out and away from the wheel chocks .
.. Stop and have someone retr ieve the wheel
chocks.
@ Tips
If you move the selector leve r of the auto­
matic transmissio n* to P before applying
the pa rking brake and before bloc king the
whee ls, you may hav e to use mor e forc e
la ter to m ove the lever out of the P p osi­
tion.
