Serv ice station fue l pumps are labe led w it h the co rrect fuel informa­
ti on fo r easy recogni tion by the user. If the diese l fuel pump is not ..,_

labeled ask the station operator what fuel is being dispensed befo re
fi lling up yo ur vehicle.
Service stations offering Diesel f uel are generally loca ted on truck
routes or major hig hways. Directo ries of Diese l fue l stations are
usually availab le at Diese l fuel stations.
Some states in t he USA require permits to purchase Diesel fuel. Check
w ith your State Mo tor Vehicle De partment.
Diesel fuel may not be available outs ide the USA and Canada. Be sure
to check before trave ling to othe r countries .
Winter operation
At t empe ratures below 20° F (- 7° C), Die sel fue l No . 2 l oses its flu idity
due to wax separation, wh ich may clog the fuel filter or tank fi lter and
keep the engine from running .
T o help t he filte r from be ing clogged by wax, the fue l fi lter in your
vehicle is automatically preheated. Preheat ing the fuel f ilter makes
operat io n of yo ur vehicle possib le with Die sel fuel No. 2 dow n to -
10° F (-24° C).
If you expect temperat ures below 5° F (-1S° C) ask yo ur fuel dealer
whether their Diesel fuel No . 2 is suffic iently w interized for the
prevailing and expected temperat ures.
If not winterized or insuff ic ie ntly w inte riz ed Diese l fuel has already
thickened to the extent that the engine w ill not start, warm the
vehicle up by leaving i t in a heated garage.
It is normal that the eng ine noise level (dieseling) is louder during the
warm-up period in winte r. It is also normal when whitish -blue smoke
comes out of t he tailpipe afte r start ing and du ring warm-up. The
amount of smoke depends on the outside temperature .
Do not let your Diesel engine idle unnecessa rily af ter a co ld start.

Changing the engine oil
The eng ine oil and oil fi lter mus t be changed according to the mileage
(kilome ters) and t ime intervals specified i n your vehicle 's Warranty &
Ma intenance booklet . Do not exceed these interva ls - harmful
deposi ts from o ld engi ne oil can reduce engine pe rfo rmance and ca n
lead to expensive engine repa irs.
C hangi ng the oil at the recommende d interva ls is so very imp ortant
because the lubricating properties of o il decrease gradually during
normal ve hicl e use. If yo u ar e not sure w hen you have yo ur oil
changed, ask your author ized Audi Service Adv isor .
Under some circumstances the eng ine o il should even be changed
more fr eq uent ly. Chang e oil mor e of ten if you d rive mostly short
distances, operate the veh icle in d usty areas or mostly under stop­
and -go t raff ic condi tion s, or when you use yo ur vehicle where tempe r­
atures stay be low free zing po int for long periods.

Engine oil consumption
To provide effective lubr ication a nd cooling for interna l eng ine parts,
a ll in ter na l c omb ustion e ngines use some oil. Oil cons umption v aries
from engine to engine and may change over the life of the eng ine .
E ngines te nd to use m ore oi l dur ing the b re a k-i n period t han t hey do
after ward, when oil consumption has stab ilized. Depending on t he
way the vehicle is driven and the operatin g cond itions, oi l cons ump ­
tion ca n be up to 1 qua rt pe r 1,200 m iles
(I liter per 2 ,000 km).
Consumption may be higher withi n th e first 3,0 00 miles (5,00 0 km).
Under nor mal co ndi tions, the rate o f oi l consu mptio n depe nds o n oil
quality as well as viscosity, engine speed ( rpm), o utside tempe rature,
roa d condi tion s, the amou nt of o il d ilution caused by co nde nsed
water or fu el residue, and oxidation of the oil. O il cons umption may
increase wi th en gine we ar ove r time, un til repl aceme nt of worn
eng ine pa rts may become necessa ry.
Because of all these var ia bles, there is no standa rd o r "norma l" rate
of oil consumption .
We urge you to check the engine oil level at
regular intervals, preferably every time you fill the fuel tank, and
always before a long trip .
The oil pressure warning light
~ is not an indicator of low eng ine
oil level. If the warning light does not go out after starting, or
flashes while driving (above 1500 rpm), a buzzer will sound . It
indicates that the oil pressure is too low. Stop the engine immedi- _.,,

_____________________________________________ C_h _ e_ c_ k_in --= g'-- a_n _d_ f_i _ll _i_n -=g ::;__ ____..
ately, check the engine oil level and add oil if necess ary. If the
engine oil level i s normal, but the light continues to flash , do not
keep driving or l et the engine idle , as damage may occur .
If you believe your engine uses too much oil, we recommend that you
cons ult your au thor ized Audi dealer so that the cause of yo ur conce rn
can be properly diagnosed. Keep in m ind that accurate measurement
of oil consump tion req uires gre at care a nd may ta ke some time. You r
Audi dealer has instructions for how to measure o il consumption
a ccu rately.

When the coolant lev el is too low, the warning light in the Auto·Check
System=>
page 35 will blink until you add coolant and t he level has
been resto red to normal. Even though there is an electric coolant
level sensor, we st ill recommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the coo ling system . In the event of
coo lant loss , the cooling system sho uld be inspected immed iate ly by
your authorized Aud i dea ler . It is not enough mere ly to add coolant.
In a
s ealed system, losses can oc cu r only if the boiling point of the
coolant is exceeded as a result of ove rheating .
& WARNING
The cooling system is under pressure and can get ve ry hot. Reduce
the ri sk of scalding from hot coolant by following the se steps.
• Turn off the engine and allow it to cool down .
• Protect your face, hand s and arms from e scaping fluid and

Tires and vehicle load limits
T here are lim its to the amo unt of load or weight that any veh icle and
any tire can carry . A veh icle that is overloade d will not handle well and
is more difficult to stop . Overload ing can not on ly lead to loss of
vehicle contro l, but can also damage important parts of the vehicle
and can le ad t o su dden t ire failure, including a b lowo ut and s udden
def lation that can ca use the vehicle to c rash .
Yo ur safety a nd t hat of your passengers also de pends o n mak ing s ure
that load limits are not exceeded . Vehicle load incl udes everybody
and everything in and on the vehicle . These loa d limits are technically
referred to as the ve hicle's
Gross Vehicle Weight Rating ("GVWR") . The
"GVWR" includes the weight o f the basic vehicle, all factory
ins talled accessories, a f ull tank of f uel, oil, coolan t and other fl uids
plus maxim um load . The max imum load i ncludes the numbe r of
passenge rs that the vehicle is intended to carry ("seating capacity")
w ith an ass umed we ight of 150 lbs (68 kg) for each passenger at a
designate d seati ng position and the total weig ht of any luggage in
the vehicle. If yo u tow a trai le r, the weight of t he t railer hitch and the
tongue weight of the loaded trailer must be included as part of the
veh icle loa d.
The
Gross Axle We ight Rating ("GAWR") is the max imum load that
can be a pplied at each o f the ve hicle 's two axles .
Th e Gross Vehicle Weight Rat ing and the Gross Axle Weight Rat ing
are listed on the safety compliance sticker label located on the
dr iver 's side B-pillar. Your A udi has 5 seat ing pos it ions, 2 in the front
and 3 in the rear for tota l seat ing capacity of 5. On vehicles with six
sea ts*, yo ur vehicl e has two fron t seat s, two se a ts i n the se co nd row
seating and two seats in the t hird row seating. On ve hicles with seven
sea ts*, yo ur veh icle has two fron t se ats , th ree seats in the se cond row
seat ing and two seats in the third row seating. Eac h seating posit io n
has a seat belt=>
page 20 1, "Safety bel ts" .
Th e fact that there is an upper lim it to your veh icle 's Gross Vehicle
We ight Rating means that the total weight of whatever is being
c arried in t he veh icle ( inclu ding t he weight of a tra ile r hi tch and the
tongue weight of the loaded tra iler) is limited . The more passengers
in the vehi cle or passenge rs who are heavier th an the stan dard
