0 Note
• Check the oil leve l using the radio or the M MI*. If the message
Please reduce oil level appears, contact your authorized Audi dealer
or other qualified workshop to have excess oil extracted if necessary .
• Audi does not recommend the use of oil additives. They may
damage the engine and adversely affect your New Vehicle
Warranty.
Safety first
<£' 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 legal regulat ions when d ispos ing of empty oil
containers. •
Changing the engine oil
We recommend that have your oil changed by an autho­
rized Audi dealer or a qualified service station.
Before you check anything in the engine compartment, always read
and heed all WARNINGS=>
& in "Working in the engine compart ­
ment" on
page 280 .
The eng ine oil must be changed accord ing to the intervals specified in
your Warranty
& Maintenance book let. This is very important because
the lubricating properties of oil diminish gradually dur ing normal
vehicle use.
Under some circumstances the engine oil sho uld be changed more
frequently. Change oil more ofte n if you drive mostly short distances,
operate the vehicle in dusty areas or under predominant ly stop-and­
go traffic conditions, or have your ve hicle where temperatures rema in
below freezing for extended periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time . This is normal and is not a
reason to change the oil mo re often than recommended .
Because of the problem of proper disposal, along with the specia l
too ls and necessary expertise required, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified
service station.
If you choose to change your oil yourself, please note the following
important information: .,_

Tires and vehicle load limits
There are limits to the amo unt of load or weig ht that any vehicle and
any t ire ca n carry. A veh icle th at is overlo ade d w ill n ot handle well and
is more difficult to stop . Overload ing can not on ly lead to loss of
vehicle co ntro l, bu t can also d amage important pa rts of the vehi cle
and can lead to sudden t ire failure, including a b lowo ut and sudden
deflation that can ca use the vehicle to c rash.
Yo ur safety and t hat of your passengers also depends o n mak ing s ure
that load limits are not e xceeded. Vehicle load incl udes eve rybody
and everyth ing in and on the ve hicle. These load limits are tech nically
refer red to as the veh icle's
Gross Vehicle We ight Rating ("GVWR").
T he "GVWR" includes t he weight of the basic vehi cle, all factory
installed accessories, a fu ll tank of fue l, o il, coo la nt and other fluids
plus maxim um load . The maxim um load includes the number of
passenge rs that the vehi cle is intended to car ry ("seating capacity ")
w ith an ass umed we ight of 150 lbs (68 kg) for each pa ssenger at a
designat ed seating position and the tota l w eight of any l uggage in
the vehicle. If you tow a trai le r, the weight o f the t railer hitch and the tongue weight of the
loaded tra ile r must be included as part of the
veh icle lo ad .
T he
Gross Axle Weight Rating ("GAWR ") is the max imum load t hat
can be a pplied at each of the ve hicle's two axles .
Th e Gross Vehicle Weight Rat ing and the Gro ss Axle Weight Ra ting
are listed on the safety compliance s ticker label located on the
dr iver 's s ide B-pillar. Audi h as 4 seat ing pos it ions, 2 in t he fro nt and
2 in the rear for total seating capacity of 4 . Each seating pos it io n has
a seat belt =>
page 189, "Safety belts" .
Th e fa ct t hat 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 arrie d in t he ve hicle (incl uding t he weight o f a trail er hi tch and the
tongue weig ht of the loaded tra iler) is limited . The more passengers
in the veh icle or p assenge rs who are he avier than the st anda rd
we ights assumed mean that less we ight can be carried as luggage.

Wheel bolts
Whe el bolts must alway s be tight en ed to th e corre ct
to rqu e.
T he design of wheel bolts is matche d to the fac to ry installed rims. If
differe nt rims ar e fitte d, the cor rec t wheel bolts with the r ight length
and co rrectly s haped bolt hea ds must be used. Th is ensures that
w heel s are fitted s ecur ely and that t he brak e sys te m fun ction s
correctly .
I n certai n circumstances, yo u may not use wheel bolts from a
different veh icle -even if it is th e sam e mode l~
page 345.
& WARNING
Improperly tightened or maintained wheel bolts can become
loose causing loss of control, a collision and serious personal
injury .
• Always keep the wheel bolts and the thread s in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled, even
if tightened to the specified torque.
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving. If the tightening torque is too high, the wheel bolts and threads can be damaged and the wheel can become
loose .
