The rear spoiler may not have extended due to
a ma lf u nction. This could change the vehicle 's
driving characteristics at high speeds . Do not
exceed 85 mph (140 km/h). Drive to your au­
thorized Audi dealer immed iate ly to have the
malfunction corrected. The co lor of the indica­
tor light depends on the ve hicle speed.
A WARNING
Dr iv ing at higher speeds w ithout the rear
spoiler dep loyed can impair handling char ­
acteristics, making the veh icle harde r to
cont ro l.
- Always make sure that the spoiler is de­
ployed when driving at speeds over
85 mph (1 40 km/h). If the rear spoiler
warning/ind icator light in the i nstr u­
ment cluster comes on, the rear spoiler
may not have dep loyed .

Braking
General information
What affects braking efficiency?
Ope rating condition s and dri ving h abit s
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving habits ¢.&, . On ve­
hicles that are either dr iven mostly in stop­
and-go c ity traff ic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often th an specified in
the
Warran ty & Maintenan ce boo klet. Failure
to have yo ur brake pads inspected can result
in reduced brake performance .
On steep slopes, you sho uld use the braking
effect o f the engine . This way, you prevent un ­
necessary wear on the b rake system. If you
must use your brakes, do not hold the brakes
down cont inuous ly. Pump the brakes at inter­
vals.
Mo istur e or road salt
U nder certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads. A
few carefu l brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered

194 Driving and en vironm ent
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A 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
sto re the full braking effect.
@) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the vehicle, 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 vehi­
cle to drive through 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
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
t ion will give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary 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 most fuel when they are ac­
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less . Let the vehicle coast
whenever possible - for example when you see
that the next traffic light is red.

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 saf ety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra iler lights must meet all reg ulations . Be
su re to check with your Audi dea ler fo r cor re ct
wir ing, swi tches 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 i nsta ll ext ended mir rors . It is important
t h at you
always have clea r vis ion to the rear .
.8, WARNING
-
Afte r removing the trailer hit ch, do no t
s tore i t in yo ur vehicle . In case of sudden
b raking, the h itch cou ld fly forwar d an d in­
ju re you or yo ur passengers .
Operating instructions
Maximum trailer weight
A tra ile r fo r you r vehicle is limited to a ty pical
cl ass 1 or class 2 tra ile r.
Trailer load distribution
B e sure the loa d in the tr aile r is held secure ly
i n place to p reven t it from shift ing forw ard,
ba ckward or sideways.
Never allow a passenger to ride in a trailer
¢&. in Driving instru ctions on page 198.
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is impo rtant that the cooling system's
perfo rmance is up to the additional load .
Make sure that the coo ling syst em has enough
f lui d.
Tire pressure
When towing a trailer , inflate the tires of your
vehicle to t he cold 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 t ires to tra iler and t ire manufac ­
turers' specif ications.
Lights
Check to ma ke s ure bot h ve hicle and trailer
lights are working proper ly.
Safet y chains
Be sure tra ile r safety cha ins are prope rly con­
nected from the trailer to the hi tch on the ve­
h icle. Leave enough s lack in the chains to per­
mit turning corners. When you install safety
chains, make sure they wi ll not drag on the
road when yo u are driving .
The cha ins shou ld cross under the tra ile r
tongue to prevent it from dropping in case o f
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration .
To obtain the best poss ible handling of vehicle
and tra ile r, p lease no te the following:
.. Do not tow a loaded tra ile r when your car it­
self is not loaded.
.,. Be especia lly ca reful whe n passing other
ve­
hicles.
.. Observe speed limits .
.. Do not d rive at the maximum permissible
speed.
.. Always apply brakes early .
.. Monitor the temperature gauge.
W eight distribution
Towing a loaded trai le r with an empty ca r re­
sults in a high ly 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 eas ier to operate and con­
trol. This means that the tow vehicle should be loaded to the extent poss ible and permiss i­
ble, while keeping the trailer as light as possi­
b le under the circumstances . Whenever possi- ble, transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tong ue load requ irements and vehicle load ing
considerations.
Speed
T he higher the speed, the mo re d iff icu lt it be­
comes for the driver to control the rig . Do not
drive at the maximum permissible speed . Re ­
duce your speed
even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill .
Red uce vehicle speed
immediatel y if the trail­
er shows the slightest s ign of sway ing.
Do not
try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds
for vehicles towing trai lers are lower than for
regular vehicles .
Always apply brakes early . When driving
down hill , shift into a lower gear to use the en ­
gine braking effect to s low the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperatur e
The coo lant temperat ure gauge ¢ page 10
must be observed carefu lly. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at h igh engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the d isp lay turn on .

A WARNING
Anyone not properly restrained in a mov­
i ng vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not p roperly wea ring the rest raints
p rov ided by A udi.
