-Audi doe s not recommend the use of oil
add iti ve s. T he y ma y damage the engine
and ad ve rse ly affect you r New Vehicle
Wa rrant y.
@ For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network or
the soil.
- Observe and follow lega l regu lations
when disposing of empty oil containers.
Changing the engine oil
We recommend that hove your oil changed by
on authorized Audi dealer or a qualified serv­
ice station .
Before you check anything in the engine com­
partment,
a lw ays r ead and heed all WARN­
ING S
c:> &. in Working in the engine comport­
ment on page 232.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance booklet. This is very important
because the lubricating properties of oil di­
minish gradually dur ing normal veh icle use.
Under some circumstances the engine oil
should be changed more frequently. Change
oil more often if you drive mostly short dis­
tances, operate the vehicle in dusty areas or
under predominantly stop-and -go traff ic con ­
d itions, or have your veh icle where tempera­
tures remain below freezing fo r extended pe­
r iods.
Detergent additives in the o il w ill make fresh
oil look dark after the eng ine has been run­
n ing fo r a short time. This is norma l and is not
a reason to change the oi l mo re often than
recommended.
Because of the problem of proper disposal,
along w ith the special tools and necessary ex­
pe rtise required, we strong ly recommend that
you have your oi l changed by an author ized
A udi dealer or a qualified service station.

244 Checking and filling
Have the battery checked when you take your
vehicle in for service. You are well advised to replace a battery that is older than 5 years .
W ith certa in types o f airbag deployment, the
battery is disconnected from the vehicle elec ­
trica l system for safety reasons¢
& in Re­
pair, core and disposal of the airbags on
page 166.
Disconnecting the battery terminals
Some veh icle functions (power window regu­
lators, for example) are lost if the battery ter­
minals are disconnected. These functions have
to be re learned after the battery terminals are
connected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
Vehicles not driven for long period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main ­
tains starting capability over a longer period
¢
page 203. Some of the convenience func­
tions may not operate, such as the inte rior
lights or the power seat adjustment . Th e con­
venience functions will be available again
when you switch on the ignition and start the
engine.
Winter operation
During the winter months, battery capacity
tends to decrease as tempe rat ures drop . This
is because more powe r is also consumed while
starting , and the headlights, rear window de ­
fogger, etc., are used more often.
Avoid unnecessary power consumption, par­
ticular ly in city traffic or when traveling on ly
short distances. Let your authorized Audi
dealer check the capacity of the vehicle bat ­
tery before winter sets in
¢ page 246. A well
charged battery w ill not only prevent starting
prob lems when the weather is cold, but will
also last longer .
(D Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery sho uld be removed and
stored where it w ill not freeze . This will
prevent it from being damaged and having
to be replaced .
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor. Before you check any­
th ing in the luggage compartment,
read and
heed all WARNINGS
¢ ,& .
Always heed the safety warnings, when work­
ing on the vehicle battery or the vehicle elec­
trical system to prevent injury.
The following WARNINGS are very
important when working on the battery:
Always heed the following WARNING SYM­BOLS and safety precautions when working
on the battery.
®
Always wear eye protection.
Battery acid contains sulfuric acid.
Always wear gloves and eye protec­
tion.
No
- sparks
- flames
- smoking.
When a battery is charged, it produ­
ces hydrogen gas which is explosive
and could cause personal injury.
Always keep the battery well out of
I
reach of children .
_&. WARNING ~
Whenever working on the battery or on
the electrical system, there is the risk of
injury, accident and even fire . Read and
heed the following WARNINGS:
-

-Only when a ll tires on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring* system can work cor­ rect ly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the d river
observe the specif ied tire pressure values
for the tires and the co rrect p ress ures for
the f un ct ion of t he tire pressure mo nitor­
ing sy stem*.
- Always inflate ti res to the recommended
and co rrec t tire pressu re befo re dr ivi ng
off.
- Driv ing wi th under infla ted ti res bend
more, letti ng them get too ho t res ulting
in t read separation, sudden t ire fail ure
and loss of control.
- Excessive spee d and/ove rloading can
ca use heat bui ld -up, sudden tire fa il ur e
and loss of control.
- If the t ire pressure is too low or too high,
the tires w ill wea r prematu rely an d the
vehicle will not hand le we ll.
-If the t ire is no t flat and you do no t have
to change a w heel imme diate ly, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Driving without va lve stem caps ca n cause
damage to the t ire va lves. To prevent this,
always make s ure that facto ry installed
valve stem caps on all wheels a re secure ly
mounted on the va lve .
@) For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire can carry .
A vehicle that is ove rloaded w ill not ha ndle
well and is more difficult to stop . Overload ing
can no t on ly lead to loss o f vehi cle con tro l,
Tire s an d wheel s 257
but can also damage important parts of the
vehicle and ca n lead to sud den tire fai lure, in ­
clud ing a b lowout and s udden def lation that
can cause the vehicle to cras h.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded . Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
Gross Vehicle We ight Rating
("GVWR ") .
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coo lant and other fluids plus
maximum load . The max imum load includes
the number of passenge rs that th e vehicle is
i n tended to car ry ("seat ing capa city") wi th an
ass umed we igh t of 150 lbs (68 kg) fo r each
passenger at a designated seating posi tion
and t he tota l weight of any luggage i n the ve­
hicle . If you tow a trai ler, the weight of the
tra iler hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
T he
Gro ss Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
T he Gross Vehicle Weight Rating and the
G ross Ax le Weig ht Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar. Your Audi has 5 seat ing
pos itions, 2 in the front and 3 in the rea r fo r
total seating capacity of 5 . Vehicles with pow­
er ind iv idual rea r seats* have 4 seat ing pos i­
tions, 2 in the front and 2 in the rea r fo r total
seat ing capac ity o f 4. Each seating position
has a safety belt~
page 144, Safety belts.
The fact that there is a n uppe r limit to you r
vehicle's G ross Vehicle We ight Rating means
t h at the to tal weig ht of whatever is bei ng car ­
ried in the vehicle ( in cl ud ing t he weight of a

ing:
- Tire rotation in tervals may d iffer from the
veh icle service inte rva ls o utlined in your
Warranty & Main tenance booklet.
- The longer o ne tire i s used in one lo cation
on the vehi cle, the more it wears at cer tain
points ; therefore, we recommend t hat you
follow the tire manufact urer's suggested
tire rotation intervals .

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in
the right direction .
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spa re tire with a t read patte rn
i n te nded fo r use in a specific direction, please
note the fo llowing:
- T he direction o f rotation is marked by a n ar­
row on the side of the tire.
- If the spare t ire has to be in stalled i n the in ­
corre ct d irection, use the sp are tire on ly
temporarily since the t ire will not be a ble to
achieve its optimum perfo rmance character­
ist ics with rega rd t o aquaplaning, noise and
wea r.
- We recommend t hat you pay pa rticular at­
tent ion to this fact during wet weat her and
t h at y ou adjust your speed to matc h road
condit ions .
- Replace the flat tire w ith a new one and
have it installed o n your ve hicle as soon as
poss ible to restore th e handli ng a dvantages
of a un id irect iona l tir e.
Notes on wheel changing
Pl ease re ad the informa tion i:> page 260, New
t ires and repl acing tires and wheels
