A WARNING
- The vehicle can also ro ll when the eng ine is
stopped.
- Unintended vehicle movement can cause se­
rious injury.
- Never leave your veh icle with the engine
running while in gear. If you must leave
your veh icle w hen the engine is r unning, ac­
tivate t he pa rking brake a nd move the selec­
tor lever to P .
- Power is still transmitted to the wheels
when the engine is running at idle . To p re­
vent the vehicle from "creeping", yo u m ust
keep your foo t on t he b rake when the en­
g in e is ru nning and the selector lever is in D/
Sor R or "tiptronic" mode is se lected .
- Do not press the a cce le ra to r peda l when
changing the se lec to r l ever posi tion while
the vehicle is s ta tionary and the engine is
r u nning .
- Never sh ift into R or P whi le driving.
- Before d riving down a s teep sl ope, redu ce
your spee d and sh ift into a lower gea r w ith
"t i ptronic" .
- Do not ride the brakes or press the bra ke
pedal too of ten o r too long when dr iv ing
down a hi ll. Constant braking ca uses the
brakes to ove rheat and substantially re­
duces brak ing performance, increases b rak­
ing d istance or causes comp lete failure of
the brake system.
- To prevent the veh icle from rol ling back
when stopp ing on inclines, always hold it in
place with the brake peda l or park ing brake .
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. An ind icator lam p. illumina tes

Intelligent Technology
When the hill descent assist is on, the current
driving speed, when your vehicle entered the in­
cline is maintained. It is only possible to switch
on the assist when driving slower than 37 mph (60 km/h). The assist works between approxi­
mately 2 and 19 mph (4 and 30 km/h). The driver
can increase or decrease the vehicle speed within
these limits by depressing the accelerator or brake pedal.
There must be however sufficient ground adhe ­
sion . The hill descent assist
cannot do its job if
the incline is icy or if the incline ground is loose
¢ ,&.
Active assistance at a specific speed up to about 19 mph (30 km/h) is shown in the instrument
cluster through a blinking indicator light •. The
indicator light shines continuously when in the
ready mode.
The system does not work at speeds between 19
and 37 mph (30 and 60 km/h) . The system is
then in the ready-mode. This is shown through
the LED turned on in the button . The system au­
tomatically switched off when you drive faster
than 37 mph (60 km/h). The LED will also go out
in this scenario.
Hill descent assist is automatically activated un­
der the following conditions:
- The LED in the button turns on ,
- the vehicle speed is lower than 19 mph (30 km/
h) ,
-the incline angle is at least around 10% .
A WARNING
-Always adapt your speed to the weather ,
road and traffic conditions . Do not let the
increased safety provided tempt you into
taking risks, because this increases the risk
of an accident.
- The hill descent assist system cannot over­
come the laws of physics. Your driving style
must always be adapted to the current road
and traffic conditions.
- The hill descent assist may not be able to
hold your vehicle at a constant speed under
all conditions while driving on an incline (for
154
example if ground under the vehicle is
loose).
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first
250 mi (400 km). They
must be "broken in" first¢& . However, you can
compensate for the slightly reduced braking
force by pressing firmly on the brake pedal. Avoid heavy braking during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub­
ject to wear, depending largely on operating con­
ditions and driving habits¢,& . On vehicles that
are either driven mostly in stop-and-go city traf­
fic or are driven hard, the brake pads should be checked by your authorized Audi dealer more of ­
ten than specified in the
Warranty & Mainte­
nance booklet.
Failure to have your brake pads
inspected can result in reduced brake perform­
ance.
On steep slopes, you should use the braking ef­
fect of the engine. This way, you prevent unnec­
essary wear on the brake system. If you must use
your brakes, do not hold the brakes down contin­
uously. Pump the brakes at intervals.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water or road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight con­ densation or after washing your car , the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
"dried" first with a few careful brake applica­
tions.
At higher speeds and with the windshield wipers
turned on, the brake pads press against the brake
rotors for a short amount of time. This action
which is not felt by the driver happens at regular .,.

Fig. 143 Permitted ball pos ition of the trailer hitch
Trailer towing weights
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissib le trailer weight is
2,200 lbs (1,000 kg). The maximum permiss ible
unbraked trailer weight is 1,650 lbs (750 kg).
These specifications apply when dr iv ing on roads
h av ing an incl ine 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 w ith a bathroom scale o r you can
measure the load at a trucking company or
weighing station.
With a
factory-installed or an aftermarket trailer
hit ch, the maximum permissib le load on the ball
hitch may not exceed 220 lbs (100 kg).
It is rec­
ommended to use the maximum permissible
l oad.
Trailer load distribution Be sure the load in the trailer is held securely in
place to prevent it from s hiftin g forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer ¢.&.
in Driving instructions on page 166.
Ball mount
The trailer hitch may only be used w ith suitable
ball mount and ball¢
fig. 143. Installation of
the hitch ball must be carr ied out in accordance
with the manufacturer's instructions.
Trailer mode
Engine cooling system
To wing 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 th e cold tire pressure lis ted under "Full
load" on the tire pressure label. The tire pressu re
label is located on the driver's side B-pi llar . In­
flate trailer t ires to trailer and tire manufactur­
ers' specifications.
Lights
T he headlight settings shou ld be checked with
the trai ler attached before driving off. Check to
make s ure 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 s lack 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
driv ing.
The chains should cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Driving instructions
Driving with o trailer always requires extra core
and consideration .
To obtain the best possib le handling of vehicle
and trailer, p lease note the following:
.. Do not tow a loaded trailer when your car itself
is not loaded.
.. Be especially care ful when passing other
vehicles .
.. Observe speed limits.
.. Do not drive at the maximum permissib le
speed.
.. Always apply brakes early.
.. Mon itor the temperature gauge .

Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a high-quality oil
which can usually be used throughout the entire
year .
Q) Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set fo rth in the Audi Owner's
Manual and Wa rranty
& Maintenance booklet.
- Use only a high qua lity eng ine oi l th at ex-
pressly complies with the Audi oil qua lity

Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubrication and cool­
ing of internal engine components, all internal
180
combust ion engines consume a certa in amo unt
of oil. Oil consumption varies from engine to en­
gine and may change significantly over the life of
the engine. Typically, engines w ith a specified
break-in period (see
c:::;, page 159) consume more
o il dur ing the break-in per iod than they consume
af ter o il consumption has stab ilized .
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscos ity of
the oil, the RPM (revo lutions per m inute) at
wh ich the engine is operated, the amb ient tem­
perature and road condit ions. Further factors a re
the amount of o il di lution from wate r co ndensa­
tion or fue l resid ue an d the oxidation level of the
o il. As any engine is sub ject to wear as mileage
builds up, the oi l cons umption may increase over
time unt il replacement of worn components may
become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil consumption can be estab­
li shed or specified. The re is no alternative to reg­
u lar and frequent checking of the oi l level, see
Note.
If the yellow engine oil level warning symbo l Ell
in the instrument cluster lights up, you sho uld
check the oil level as soon as possible
c:::;, page 181. Top off the oil at your earliest con­
venience
c:::;,page 181.
A WARNING
Before you check anyth ing in the e ng ine com­
partment, always read and heed all WARN­
I NGS
c:::;, .&. in Working in the engin e compart­

(D Note
Driving w ith an insuffic ient oil level is likely to
cause severe damage to the eng ine.
(D Tips
- The oil pressure warn ing d isplay. is not
an indicator of the oil level. Do not rely on
it. Instead, check the oil level in your en­

mend that you consu lt an autho rized Aud i
dealer to have the cause of your concern
properly d iagnosed . Keep in mind that the
accurate measurement of oil consumption

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­ tion .
Before you check anyth ing in the eng ine compart­
ment,
a lways r ead and heed all WARNINGS ¢&.
in Working in the engine compartment on
page 177 .
The engine oil must be changed accord ing to the
intervals specif ied in your Warranty
& Mainte­
nance booklet. This is very important because the
lubricat ing propert ies of oil d iminish gradually
du ring normal vehicle use.
Under some circumstances the eng ine o il should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances, ope rate
the vehicle in dusty areas or under predominantly
stop-and-go traffic cond it ions, o r have your vehi­
cle where temperatu res remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
look dark afte r the engine has been ru nning fo r a
short t ime. This is no rmal and is not a reason to
change the oil more often than recommended.
Because of the prob lem of proper disposa l, along
with the special tools and necessa ry expe rt ise re­
qu ired, we s trong ly recommend that you have
182
you r oi l changed by an authorized Audi d ealer or
a qua lified service station.
If you choo se to chang e your oil your self, please
note the follow ing important information:
& WARNING
To reduce the risk of persona l injury if you
must change the eng ine oil in yo ur vehicle
yourself:
- Wear eye protection .
-
-To reduce the r isk of b urns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil d rain plug with yo ur
fingers, stay as far away as possible. Always
keep your forearm parallel to the gro und to
he lp prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one la rge enough to hold at
least the tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine o il is
harmf ul to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
(D Note
Never mix oil additives with your engine oil.
These additives can damage your engine and adverse ly affect your Audi Limited New Vehi­
cle Warranty.
@I For the sake of the environment
- Before chang ing you r oi l, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used engine o il properly.
Do not dump it on garden soi l, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine o il by tak ing it to a used
eng ine oil collect ion fac ility in your area, or
contact a service station .

Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention.
T he cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed . The coolant consists of a mixture of
specially condit ioned water and the manufactur ­
er's glycol-basedcoolant add itive G 13 antifreeze
with anticorrosion additives (SO% for USA mod­
e ls; 60% for Canada models) . This mixt ure bot h
assures the necessary frost protec tion and pro­
tects meta l components in the engine's cooling
system from corrosion and scaling . It also raises
the boiling point of the coolant.
D o not red uce the concent ration of the coolant in
the summer by add ing p la in water.
The propor­
tion of coolant addit ive mu st be at least 50 %
but not more than 60 %
to mainta in antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
g ine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to :
- -31° F(- 3S°C)USA
