206 Driving and en vir onm ent
Driving through water
on roads
Note the following to avoid vehicle damage
when driving thro ugh water, for example on
flooded roads:
- The wate r must not be any higher than the
bottom of t he vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through wate r, 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
sto re the full braking effect.
@) Note
- Vehicle components such as the eng ine,
transmission, suspension or electr ical
system can be severely damaged by driv­ i ng th rough water.
- Always switc h off the Start-Stop-System
when driving through water~
page 80 .
(1) Tips
-Check the depth of the water before dr iv­
i ng th rough it.
- Do not stop the ve hicle, dr ive in reverse
or switch the engine off whe n driving
t hr ough water .
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep fo r you r vehi­
cl e to drive th rough safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
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, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- oper ating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economica lly, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRON MEN TAL PROTEC TION AG ENCY
( EP A) and Transpo rt Canada may no t corre­
spond to your actual consump tion on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con ­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the mos t fu el when they are ac­
ce le rat ing. If yo u ant icipate what is going to
happen next, you will need to brake less and,
t hu s, acce le rate less . Let the vehicle coast
whenever possible -for examp le when you see
t h at the next traff ic light is red.

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
11-Try and keep well below your car's maxi-
mum speed.
Accelerating gently reduces fuel consump­ tion, engine wear, and does not disturb the
environment.
F ue l consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
11-Shut the engine off when you are not driv­
ing the vehicle.
"" Do not warm up the veh icle by letting the
engine run at idle .
The idling phase is automat ically reduced for
vehicles w ith the Start/Stop system . It is effi­
cient to switch
off the engine in vehicles with­
out the Start-Stop-System when stopped at ra il road crossings and long red lights. Turning
the eng ine
off for just 30 -40 seconds saves
mo re fuel than is burned by s tarting the en­
gine again.
It takes a long time fo r the engine to wa rm up
fu lly when it is running at idle. Howeve r, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at h igh rpms while the engine is
still warming up.
CD Note
Do not leave engine idling unattended af­
ter starting. If warning lights shou ld come
on to indicate improper operation, they
Dri vin g and en vironm ent 207
would go unheeded. Extended idling a lso
produces heat, which could result in over­
heating or other damage to the veh icle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
11-Have your vehicle serviced at reg ular inter-
vals .
By having your ve hicle reg ularly se rviced by an
Audi dealer he lps to ensure that it runs prop­
erly and economically . The condition of your
vehicle not only affects its safety and ability to
ho ld its va lue, it also affects
fuel co nsump ­
tion .
Chec k your oil e ach t ime you fill y our t ank.
T he amou nt of o il used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reac h its lowest value after a certa in
mileage has bee n driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also applies to fuel consumption and en­ gine output .
CD Note
-Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Ma in­
tenance book let . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impai r the function of the
em ission cont ro l system and cou ld lead
t o damage.
- Do not alter or remove any component of
t he Emission Control System unless ap­
proved by the manufacture r.
- Do not alter or remove any devi ce, such
as heat shie lds, switches, ign ition w ires,
valves, which are designed to protect
your vehicle's Emission Control System

208 Driving and environment
and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips.
,.. Try to avoid driving short distances with a
cold engine.
The engine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effectively.
Just after starting, a cold engine in a mid-size
car only achieves a fuel economy of 6-8 miles per gallon (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 miles (4 km),
the engine is at its proper operating tempera­
ture 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
regard. Your car consumes more fuel in the
winter than in the summer.

Cleaning and protect ion
General information
Regular core preserves vehicle value.
Any automobile is exposed to industrial
fumes , corrosive road salt, etc. A well cared
for Audi can look like new many years after
purchase . Regu lar and correct care w ill con­
tr ibute to maintaining the beauty and value of
your Aud i.
F u rth ermor e, good c are may be a conditi on

Your authorized Audi dealer has a variety of
dedic ated veh icle-car e products and can ad ­
vise which ones to use for cleaning the exter i­
or and interior of your vehicle.
Whether you use products recommended by
Aud i or other commercially available clean ing
agents, please make sure you apply them cor­
rectly .
A WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caut ion labels.
- Always read directions on the container
before using any product. Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated
and have to be diluted .
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail polish remover or other volatile
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ign it ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, e tc. w ithout pro­
tecting your hands and arms. You may c u t yourself on sharp -edged metal parts .
Cleaning and protec tion 213
- Moisture and ice on brakes may impair
brak ing effic iency¢
page 199, General
information.
Test the brakes carefully
each time you wash the vehicle.
@) For the sake of the environment
Select on ly environmentally friend ly clean­
i ng products . Leftover cleaning products
should not d isposed of in the household
waste.
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental i n­
fluences is
frequent washing and waxing . How
often t his is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasonal and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle
body, the more lasting their destructive ef­
fects wi ll be . High temperatures caused by ex­
posure to intense sun light intens ify the corro­
s ive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekl y washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferab ly in a
professional car wash .

to use soapy water .
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
ing your vehicle. Never clean the head­
lights w ith a dry cloth or sponge. Use a
wet cloth or sponge. It is best to use
soapy water .
@ For the sake of the environment
Only wash the vehicle in facilit ies specially
designed for that purpose. Th is w ill reduce
the risk of d irty water contaminated with
oil from entering the sewer system . In
some areas, washing veh icles outs ide of
t hese facilit ies is prohib ited.
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 .
.,. Befo re using the power washe r, make sure
you have read and understood the WARN­ INGS ¢
A. in General information on
page 213.
.,. Always fo llow the operating instructions for
the power washer .
.,. Make sure that the jet on the spray hose
produces a "fan shaped spray" .
.,. Do
not ho ld the spray no zzle too close to
soft mate ria ls .
Keep a d istance from soft materials such as
rubber hoses or insulat ing mater ial as we ll as
sensors and camera lenses .
When clean ing the vehicle w it h a power wash­
er
always follow the operating instructions.
This applies particularly to the operating pres­
sure and the spraying distance . Do not po int
the spray directly at t he sea ls around the side
windows, aro und the doors, o n the rea r lid or

Do no t use a high-p ressure power w asher to
remove snow and ice .
Do not use a jet which sprays wate r in a d irect
stream o r one that has a rotating jet.
Water temperature should not exceed 140 °F
(60 °() .
A WARNING
Neve r wash t ires with a jet that sprays wa­
ter in a direct stream . Thi s could cause in­
v isible damage to the t ires and we aken
them, even if the spray is from a re lative ly
l ong dis tance and for a short time. Dam ­
aged and wea kened tires can fail and cause
accidents and personal in jury.

224 Cleaning and protection
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Al way s switch o ff t he ign ition b efore clean ­
ing the engi ne
c:> &. .
Plenum p ane l
Remove leaves from the plenum pane l in front
of the windshield under the engine compart­
ment. This p revents the water drain holes
from becoming blocked, and it preven ts de­
bris from enter ing the veh icle inter ior through
the heating and venti lation ducts.
Cor rosion protecti on
The engine compartment and transmission
have been corrosion-protected at the factory.
Good anti -corrosion treatment is very impor ­
tant, particular ly in the winter. If the vehicle
is frequent ly driven on sa lt treated roads, the
entire engine compartment and plenum panel
should be thoroughly cleaned at the end of
winter and retreated to prevent salt damage .
At the same time, the underside of the vehicle
should be washed as well.
If the engine compartment is cleaned at any
time with grease removing solut ions
1>, or if
you have the engine washed, the anti-corro­
sion treatment is a lmost always removed as
well. It is therefore essential to have a long­
l asting co rrosion protection reapp lied to all
surfaces, seams, joints and components in the
engine compartment .
&_ WARNING
Be aware: The engine compartment of any
motor vehicle is a potentially hazardous
area.
- Before working in the engine compart­
ment, be sure to read the informat ion
c:> page 230.
- Before reaching into the front pane l, al­
ways switch off the ignition. Otherwise,
1l Use o nly the co rrect cle anin g so lu ti on s. Never use gas­
o lin e or d ie se l fuel.
the windshield wiper system could unin­
tentionally be switched on, possibly
causing personal injury from the moving
wiper linkage .
- Never reach into the area around or
touch the rad iator fan. The auxiliary fan
is temperature controlled and can sw itch
on suddenly- even when the ignition is
off.
- Do not wash, wax or dry the eng ine with
the engine running. Mov ing or hot parts
could injure you.
- Do not clean the underside of the chas­
sis, fenders, wheel covers, or other hard
