@ Tips
-The oil pres sure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead , check the oil level in
your engine at regular intervals, pref­
erably each t ime you refuel, and always
before going on a long trip.
- If you have the impression your engine
consumes excessive amounts of oil, we
r ecommend that you consult your Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate measurement of oil con­
sumption requires great care and may
take some time. Your Audi dealer has in ­
str uctions about how to measure oil con­
sumption accurately.

252 Tires and wheels
-Always inflate tires to the
recommended and correct
tire pressure before driving
off .
-Driving with underinflated tires bend more, letting
them get too hot resulting
in tread separation, sudden
tire failure and loss of con­
trol.
-Excessive speed and/over­ loading can cause heat
build-up, sudden tire failure
and loss of control.
-If the tire pressure is too low or too high, the tires
will wear prematurely and the vehicle will not handle
well.
- If the tire is not flat and you
do not have to change a
wheel immediately, drive at
reduced speed to the near­
est service station to check
the tire pressure and add air
as required.
@ Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem caps on all
wheels are secure­
ly mounted on the valve.
@) For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion.
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehi­
cle and any tire can carry. Ave ­
hicle that is overloaded will not
handle well and is more diffi­
cult to stop. Overloading can not only lead to loss of vehicle
control, but can also damage
important parts of the vehicle
and can lead to sudden tire fail­
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash.
Your safety and that of your
passengers also depends on
making sure that load limits are
not exceeded. Vehicle load in­
cludes everybody and every­
thing in and on the vehicle.
These load limits are technical­
ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR "). .,..

M N
0 <.J 'SI: ,...., \!) 1.1'1 ,...., 1.1'1 ,....,
The "GVWR" includes the
weight of the basic vehicle, all
factory installed accessories, a
full tank of fuel, oil, coolant and other fluids plus maximum
load. The maximum load in­
cludes the number of passen­
gers that the vehicle is intend­
ed to carry ("seating capacity")
with an assumed weight of 150 lbs (68 kg) for each pas­
senger at a designated seating
position and the total weight of
any luggage in the vehicle. If
you tow a trailer, the weight of the trailer hitch and the tongue
weight of the loaded trailer
must be included as part of the
vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of
the vehicle's two axles.
The Gross Vehicle Weight Rat­ ing and the Gross Axle Weight Rating are listed on the safety
compliance sticker label locat­
ed on the driver's side B-pillar.
Your Audi has 5 seating posi­
tions, 2 in the front and 3 in the rear for total seating capacity
of 5. Each seating position has
Tires and wheels 253
a safety belt¢ page 136, Safe­
ty belts.
The fact that there is an upper
limit to your vehicle's Gross Ve­
hicle Weight Rating means that
the total weight of whatever is being carried in the vehicle (in­
cluding the weight of a trailer
hitch and the tongue weight of
the loaded trailer) is limited.
The more passengers in the ve­
hicle or passengers who are
heavier than the standard
weights assumed mean that less weight can be carried as
luggage.
The tire pressure label on your
Audi also lists the maximum combined weight of all of the
occupants and luggage or other
cargo that the vehicle can carry.

loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immediate ly.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed.
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch (10,5 mm), including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
q(D _ For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
Tires and wheels 265
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different sizes . Always make sure to follow the in­
structions provided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
([) Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severely dam­
age the wheelhouse and other parts of
the vehicle.
(D Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
vehicles with all-wheel drive.
