Gradient angle
The number of meters in altitude gained over a distance of 109 .4
yards or 100 meters (grade) are given as a percentage or degrees.
Information about the gradient the vehicle can climb under its own
power (depends in part on the road surface and engine power).
Maximum permitted grade: 31
°
Lateral angle (slope of vehicle)
Indicates the angle up to which the vehicl e can be driven diagonally
or across the fall line on a slope without the vehicle tipping over s ide­
ways (depends on center of gravity). Maximum permitted late ral
angle: 35°
Breakover angle
Indicates the angle up to which the vehicle can dr ive over a ramp at
low speed without the underside of the vehicle hitting the edge of the
ramp.

Trailer towing
Driving with a trailer
General information Your Audi was design ed primarily for passenger transpor ­
tation .
If you plan to tow a t rai ler, p lease rem emb er that the add itiona l load
wi ll affect durab ility, economy and performance.
T railer tow ing not on ly p laces mo re s tress on the vehicle, it a lso calls
for more concentrat ion from the driver.
For this reason, a lways follow the ope rating and dr iv ing instr uctions
prov ided and use common sense .
(D Note
If you are going to tow a t ra iler , you must ac tivate the tra ile r ope ra­
tion mode ::::;,

Technical requirements
Trailer hitch
Use a we igh t-car rying hit ch confo rm ing to the g ross tra ile r weig ht.
The hitch must be suitable for your vehicle and tra iler and must be
mou nted secure ly o n th e veh icle's chassis a t a
te chnically sound loca­
tion. Use only a trailer hitch with a removab le ba ll mount. Always
check w ith the tra iler h itch manufacturer to ma ke sure tha t you are
using the correct hitch .
Do not use a bumper hitch .
The hitch must be i nstalled in such a way t hat i t does not interfe re
w ith the impact-absorbing bumper system. No mod ificat ions should

ment Safety first Vehicle operation
be made to the vehicle exhaust and b
rake systems. From time to
time, check that all hitc h mounting bo lts rema in securely fastened.
Whe n you are no t towing a trai ler, remove the trailer hi tch ba ll
mount. This prevents the hitch from caus ing damage should your
vehicle be s truck from behind::::;,& .
Trailer brakes
If your trailer i s eq uipped w ith a b raking system, che ck to be s ure that
it conforms to all regulat ions.
T he tra iler hyd raulic brake system must not be directly connected to
the vehi cle's hydraul ic brake system ::::;, & .
Safety chains
Always use safety chains betwee n your vehicle and t he tra iler .
Trailer lights
Trailer lights must meet all regulat ions. Be sure to check w ith your
au thor ized A udi deale r for co rrect wi ring, switc hes, and re lays.
Mirrors
If you are unab le to see the traff ic beh ind you us ing t he regular
outside m irro rs, then you
must install extended mirro rs. It is impor­
t an t th at yo u
always have cle ar vision to the re a r.
& WARNING
• If a trailer has electrical brakes please note that these brakes

Driving instructior,s
Driving with a trailer always requires e xtra care and
consideration.
To obtain the best possib le handling of ve hicle a nd trailer ,
please note the following :
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especia lly careful when pass ing other vehicles .
- Observe speed limi ts.
- Do not drive at the maximum pe rmissible speed.
Controls and equip­
ment Safety first Vehicle operation
- Always apply brakes early.
- Mo
nitor the temperature gauge.
Weight distri but ion
T owing a loaded trailer with an empty car results in a highly unstable
distribution of we ight . If t his cannot be avoided , drive at very low
speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that the
tow veh icle shou ld be loaded to the extent poss ible and permissib le,
wh ile keeping the tra ile r as lig ht as poss ible unde r the ci rc u mstances.
Whe never possible, transfer some cargo to the luggage compart ­
me nt o f the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
The higher the speed, the more d ifficult it becomes for the driver to
control the r ig . Do not dr ive at the maxim um permiss ible speed .
Reduce your speed eve n more if load, weather or w ind conditions are
unfavorable -particular ly when going downhill.
Reduce vehicle speed
immed iately if the tra ile r shows the slightest
sign of swaying.
Do not tr y to stop the s wayi ng by a ccele rating .
Observe speed lim its. In some areas, speeds for veh icles towing
trailers are lowe r than for regular veh icles .
Always apply brakes early. When driving downhi ll, shift into a lower
gear to use the engine brak ing effect to slow t he ve hicle . Use of the
brakes alone can cause them to overheat and fa il.
Coolant temperatur e
The coo lant temperature gauge=> page 10 must be observed care­
fu lly. If the needle moves close to the upper end of the sca le, reduce
speed immediately and/or turn off the air conditioner.
If the coo lant temperature warning light in the instrument clus ter
starts flash ing
- F- , pull off the road, stop and let the engine idle for
about two m inutes to prevent hea t buil d-up.

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

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 a 1 quart per 1,200 miles
(I lite r per 2,000 km) .
Consumptio n may be higher withi n th e first 3,000 m iles (5, 000 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 ::;__ ____.fflll
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.
