Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa
tion, which may clog the fuel filter or tank fil
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fuel filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No . 2 down to -10° F (-24° C).
If you expect temperatures below 5° F
(-15° C) ask your fuel dealer whether their
Diese l fuel No. 2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
Diesel fuel has already thickened to the extent
that the engine will not start, warm the vehi
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die
seling) is louder during the warm-up period in
winter.
It is also norma l when whitish-blue
smoke comes out of the tailpipe after start ing
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine id le unnecessari
ly after a cold start. Driving off slowly will
shorten the warm-up period .
A WARNING
-Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in serious engine damage and per
sonal injury.
- Never use fuel line anti-freeze offered for
gasoline engines .
0 Note
- Refueling with gasoline when your vehi
cle has a diesel engine can cause very se
rious and expens ive engine and fuel sys
tem damage that is not covered by any
A udi Limited Warranty.
- If you put any amou nt of incorrect fuel in
the fuel tank, do not start the engine un-
-
Fuel supply and filling your fuel tank 251
der any circumstances. Immediately con
tact the nearest authorized Audi dea ler
or authorized Audi Service Fac ility for as
sistance. These fuels contain substances
that can severely damage the fuel sys
tem and the engine if the engine is start
ed .
- Veh icles with diesel engines must never
be refueled or driven with gasoline, kero
sene, heating oil, or other non-specified
fuels that have not been expressly ap proved for use with the diesel engine.
Other kinds of fuel can cause serious
damage to the fuel system and the en
gine that is not covered by any Audi Lim
ited Warranty.
- If Diesel fuel should get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por
tion with soap and warm water. Do not
allow D iesel fuel to remain on connect
ing hoses . They may develop leaks and
cause serious damage.

Your vehicle fuel tank has an on-board refuel

274 T ire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al
ways stop as soon as it is safe to do so
and check the wheels and tires for dam
age.

Glossary of tire and loading terminology
Accessory weight

power brakes, power windows, power seats,
radio, and heater, to the extent that th ese

Aspect ratio

Bead
means the part of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead separation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire . typ
ica l in those seasons . Audi recommends
using winter tires during the winter
months . Low temperatures signif icant ly
decrease the e lasticity of summer tires,
which affects tract ion and brak ing ability.
If summer tires are used in very co ld tem
peratures, cracks ca n form on the tread
bars, res ulting in permanent tire damage
that can cause loud driving no ise and un

th is type of damage .
Cold tire inflation pressure
means the tire p ressu re recommended by t he
vehicle manufacturer fo r a tire of a des igna ted

t h e three hour period before the tire pressure
is measured or adjusted.

and at h igher inflation pressures than the cor

be identified as "XL", "x l" , "EXTRA LOAD", or

(D Note
Dr iving without va lve stem caps can cause
damage to the t ire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secu re ly
mounted on the va lve.

Underinflated tires will a lso increase the

Tires and vehicle load limits
There are limits to the amount of load or
weight t hat any veh icle and any t ire ca n car ry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in
cluding a blowout and sudden deflation that
can cause the ve hicle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everyth ing in and on the vehicle. These
load limits a re tech nica lly referred to as the
ve hicle's
Gross Veh icle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
ve hicle, all factory installed accessories, a full
tank of f uel, oil, coo lant and othe r fluids plus
max imum load. The maximum load includes
the number o f passenger s that the ve hicl e is
intended to carry ("se ating capacity") w it h an
assumed weig ht o f 150 lbs (68 kg) for each
passenger at a designated seating position
and the tota l weight of any luggage in the ve
h icle. If you tow a trailer, the weight of the
trailer hitch and the tong ue weight of the
Tire s an d wheel s 281
loaded tra ile r must be included as part of the
vehicle load .
T he
Gro ss Ax le Weight Rating (" GAWR") is
the max imum load th at can be applied at each
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and t he
G ross Ax le Weig ht Ra ting are l iste d on the

hicle weight distribution and balance.
This might happen, for example, when
heavy components such as the engine
block or transmission are removed .
- When removing heavy components like
these, anchor vehicle to hoist or add cor
responding weights to maintain the cen
ter of gravity. Otherwise, the vehicle
might tilt or slip off the hoist, causing
serious personal injury.
(D Note
- Be aware of the following points before
lifting the vehicle:
-The vehicle should never be lifted or
jacked up from underneath the engine
oil pan, the transmission housing, the
front or rear axle or the body side
members. This could lead to serious
damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be
inserted between the floor jack and
the lift points.
- Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity
of the hoist.
- Before driving over a workshop hoist,
ensure that there is sufficient clear
ance between the hoist and low parts
of the vehicle.
