Trailer towing tips
Important to know
Your vehicle hand les different ly when towing
a trailer because of the additional weight and
different weight distribution. Safety, perform
ance and economy wi ll greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turning, stopp ing and backing up in an area
away from traffic. Keep practicing until you have become completely familiar with the way
your vehicle-trailer combination behaves and responds.
Backing up is difficult and requires practice.
Backing up with a trai ler genera lly requires
steering action opposite to that when backing up your vehicle without a trailer.
Maintain a greater distance between your ve
hicle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turn ing radius .
When passing, remember that you cannot ac
celerate as fast as you normally would be
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your tra iler before chang
ing lanes aga in.
Avoid jerky starts, sharp turns or rapid lane
changes .
(D Tips
-Do not tow a tra iler during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re
quire more frequent maintenance due to
the extra load
q page 293.
Parking on a slope
Do not park on a slope with a trailer . If it can
not be avoided, do so only after doing the fol lowing:
When parking:
.. App ly the foot brake.
.. Have someone place chocks under both the
vehicle and the trailer wheels .
.,. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load.
.. Turn the wheels towards the curb.
.. App ly the parking brake.
.. Place an automatic transmission* in
P, re
spectively a manual transmission in first or reverse gear.
When restarting after parking:
.. App ly the foot brake.
.. Start the engine.
.. Move the se lector lever to
D , respectively a
manual transmission in first gear .
.. Release the parking brake and slow ly pu ll
out and away from the wheel chocks.
.. Stop and have someone retr ieve the wheel
chocks .
(D Tips
If you move the selector lever of the auto
matic transmission* to
P before applying
the parking brake and before blocking the
whee ls, you may have to use more force
lat er to move the lever out of the
P posi
tion.

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil .
The engine in your Audi is a sophisticated
power plant that was bu ilt to exacting specifi
cations . This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the right oil
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to
day than it did years ago . Audi has developed
a specia l quality standard for engi ne oil that
will help assure that your vehicle's engine will
get the lubrication it needs for proper opera-
tion. .,..
-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 tire failure
and loss of vehicle control.
Glossary of tire and loading terminology
Accessory weight
means the comb ined weight (in excess of
those standard items wh ich may be rep laced)
of automa tic tra nsmission, power steering,
power br akes, power w indows, power sea ts,
radio, and heater, to the ex tent that these
items are avai lab le as factory -installed equip
ment (whether installed or not).
Aspect ratio
means the rat io of the height to the w idt h of
the tire in percent. Numbers of 55 or lower in
d icate a low sidewall fo r improved s teer ing re
sponse and better overall handling on dry
pavement.
Bead
means the pa rt of the t ire t hat is made o f
s teel wires, wrapped o r rein force d by ply cor ds
and that is shaped to fit the r im.
Bead separation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire.
Cold tire infl ation pressure
means t he tire pressure recommended by the
vehicle manufacturer for a t ire of a designated
size that has not been dr iven for more than a
couple of miles (kilometers) at low speeds in
the three hour period before the tire pressure
i s measu red or adjusted.
Tire s an d wheel s 253
-If you notice un usua l vibration or if the
veh icle pulls to one side when driv ing, a l
ways stop as soon as it is safe to do so and check the wheels and tires for dam
age.
Curb weight
mea ns the we ight of a motor ve hicle w it h
standard equipment in cl ud ing t he maximum
capa city of fuel, o il, and coolant, ai r cond i
tion ing a nd addi tional weig ht o f optiona l
equipment .
Extra load tire
means a t ire design to operate at h igher loads
and at higher inflation pressures than the cor
respondi ng s tanda rd tire. Extra load tires may
be identified as "X L", "xl", "EXTRA LOA D", or
"R F" on the sidewall .
Gross Axle Weight Rating ("GAWR ")
mea ns the load-carry ing capac ity of a s ingle
axle system, measured at the tire-ground in
te rfaces.
Gross Vehicle Weight Rating ( "GVWR ")
means the maximum total loaded we ight of
t h e ve hicle.
Groove
means the space between two adjacent tread
ribs.
Load rating (code )
means the maximum load tha t a t ire is rated
to carry for a given inflation pressure. Yo u
may not find this information on all tires be
ca use it is not required by law.

262 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv
ing style.
Fig. 212 Tire tread: tread wear ind icators (TWI)
_____ __,.J)
Fig. 213 Rotating t ires for more even wear
Tread Wear Indicator (TWI)
The origina l tires on your veh icle have
1/16 inch (1.6 mm) high "wear indicators"
¢
fig . 212 running across the tread. Depend
ing on the make, there will be six to eight of
them evenly placed around the tire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn tires must be replaced .
Different figures may apply in other countries
¢ & .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
¢ page 258.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota
tion intervals. Please remember the follow
ing:
- Tire rotation intervals may differ from the
vehicle service interva ls outlined in your
Ma intenance and Warranty Booklet .
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals .
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown¢
fig. 213.
-Extra care must be taken when rotating di-
rection-specific tires¢
page 279.
Wheel balancing
The wheels on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal
anced, resulting in vibrations you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces
sive tire wear, impairing the safety of the vehi
cle. If tires show excessive wear, have the
whee l alignment checked by an authorized
Audi dealer or qualif ied workshop.
All wheel drive
Vehicles with quattro ® must a lways have tires
of the same size, construction and tread type.

wheels on your vehicle to ensure that the re
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly .
Tire pressure indicator appears
Appl ies to vehicles: w ith t ire pressure monitoring sys te m
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig . 2 15 Display: underin flati on wa rning
Fig. 216 Disp lay: System malfunction
Using the ABS sensors, the tire pressure moni
tor ing system compares the t ire tread circum
fe rence and vibration characteristics of the in
d iv idual tires.
If t he pressure decreases in one
or mo re tires, th is is indica ted in the instru
