drive at the maximum permissible speed. Re
duce your speed even more if load, weather or
wind condit ions are unfavorable -part icularly
when going downhill.
Reduce vehicle speed
immediately if the trail
er shows the slightest sign of swaying .
Do not
try to stop the swaying by accelerating.
Observe speed limits . In some areas, speeds
for vehicles towing trailers are lower than for
regular vehicles .
A lways apply brakes early. When driving
downhill, shift into a lower gear to use the en
gine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge c:> page 10
must be observed carefully. The coo lant tem
perature can increase if you drive on long in
clines in a low gear at high engine speeds. Re
duce your speed immed iate ly if the L EDs in
the top part of the display turn on.
F or more information about indicator lights,
refer to.

A WARNING
Anyone not properly restrained in a mov
ing vehicle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not properly wear ing the restra ints
provided by Aud i.
Trailer towing tips
Important to know
Your veh icle hand les different ly when tow ing
-
a trailer because of the addit ional weight and
d ifferent weight distribution . Safety, perform
ance and economy will greatly depend on how
carefully you load your trailer and operate
your ng .
Before you actually tow your trailer, practice
turning, stopp ing and back ing up in an area
away from traffic. Keep practicing until you
Trailer towing 201
have become completely familiar with the way
your vehicle-trai ler combination behaves and
responds .
Backing up is difficult and requires practice .
Backing up with a t railer generally requires
steering action opposite to that when backing
up your vehicle without a tra iler.
Maintain a greater distance between your ve
hicle and the one in front of you . You wi ll need
more room to stop. To compensate for the
trailer, you w ill need a larger than normal
turning rad ius.
When passing, remembe r that you cannot ac
ce lerate as fast as you norma lly would be
cause of the added load. Make sure you have
enough room to pass. After passing, allow plenty of room for your trailer before chang
ing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes.
(D Tips
- Do not tow a trailer 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
c:> page 280.
Parking on a slope
Do not park on a slope with a trailer. If it can
not be avoided, do so only a~er doing the fol
lowing:
When parking:
.,. App ly the foot brake.
.,. Have someone p lace 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 .
.,. Apply the parking brake .
.,. Select the P selector lever posit ion .
When restarting after parking:
.,. Apply the foot brake.

236 Tires and wheels
-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 which may be rep laced)
of automatic transmission, power steering, power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory -installed equip
ment (whether installed or not) .
Aspect ratio
means the ratio of the he ight to the w idth of
the tire in percent. Numbers of 55 or lower in
dicate a low sidewall for improved steering re
sponse and better overall handling on dry
pavement.
Bead
means the part of the tire that is made of
steel wires, wrapped o r reinforced by ply cords
and that is shaped to fit the r im.
Bead separation
means a breakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire.
Cold tire inflation pressure
means the tire pressure recommended by the
vehicle manufacturer for a tire of a designated size that has not been driven for more than a
couple of miles (kilometers) at low speeds in
the three hour period before the tire pressure
is measured or adjusted. -
If you notice unusual 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
means the weight of a motor vehicle w ith
standard equipment including the maximum
capacity of fuel, oil, and coolant, air condi
tioning and additional weight of 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
responding standard tire. Extra load tires may
be identified as "XL", "xl", "EXTRA LOAD", or
"R F" on the sidewall .
Gross Axle Weight Rating ( "GAWR ")
means the load-carrying capacity of a s ingle
axle system, measured at the tire-ground in
terfaces .
Gross Vehicle Weight Rating ("GVWR")
means the maximum total loaded weight of
the vehicle.
Groove
means the space between two adjacent tread
ribs .
Load rating (code)
means the maximum load that a tire is rated
to carry for a given inflation pressure. Yo u
may not find this information on all tires be
cause it is not required by law.
Maximum load rating
means the load rating for a tire at the maxi
mum permissib le inflation pressure for that
tire.

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.

Tread Wear Indicator (TWI)
The origina l tires on your veh icle have
1/16 in ch (1.6 mm) high "wear ind icators"
c::> fig . 185 run ning across the tread. Depend
ing on the make, there will be six to eight of
them evenly p laced around the t ire . Marks on
the t ire s idewall (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced.
Different fig ures may apply in other countries
c::> & .
Tir e pressure
Incorrect tire pressure causes premat ure wear
and can cause sudden tire blow-out . For th is
reason, tire pressure must be checked at least
once a month
c::> page 241.
Dri ving sty le
Driving fast around curves , heavy acceleration
and hard braking increase tire wear. Tires and wheels 245
Rotating tires for more even wear
For all four tires on your ve
hicl e 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 inte rvals. Please remember the follow
ing :
- Tire rotation intervals may differ from the
veh icle service inte rva ls o utlined in your
Warranty & Maintenance 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 manufactu rer 's suggested
tire rotation intervals .
- Vehicles w ith front-wheel dr ive exper ience
more tread wear on the front wheels com
pared to all -wheel d rive (quattro ®).
- Please rotate tires as shown
c::> fig. 186.
-Extra care must be taken when rotat ing di-
rection-specific tires
c::> page 264 .
Wheel balancing
The wheels on new veh icles are balanced .
However, various situations during everyday
driving can cause them to become unba l
anced, resulting in vibrat ions you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, s uspension
and t ires. A whee l must also be reba lanced
when a new tire is insta lled.
Inco rrect wheel alignment
Incorrect wheel alignment can cause exces
sive tire wear, impair ing the safety of the vehi
cle . If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualified workshop.
All Wh eel Driv e
Vehicles wi th quattro ® mus t always have tires
of the same size, construction and tread type. For details see
c::> page 191.

254 Tires and wheels
remain continuously illuminated. This se
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminat
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea
sons, including the installation of replace
ment or alternate tires or wheels on the vehi
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your veh icle to ensure that the re
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Appl ies to vehicles: with tire 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. 188 Display: underinflation warning
Fig. 189 Display: System malfu nction
Using the ABS sensors, the tire pressure moni
toring system compares the tire tread circum
ference and vibration characteristics of the in
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the instru- ment
cluster with a warning symbol
[I] and a
message
r=> fig. 188.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad
justed (e.g. when switching between partial
and full load pressure) or after changing or re
plac ing a tire on your vehicle
r=> page 255. You
can find the recommended tire pressures for
your vehicle on the Label on driver's side 8-pil lar
¢ page 239.
Tire tread circumference and vibration charac
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat -
ed or replaced but the TPMS was not reset
r=> page 255.
Warning symbols
[I] Loss of pressu re in at least one tir e ¢ ,&. .
Check the tire or tires and replace or repa ir if
necessary. The indicator light

If IIQIS, appears after switching the ignition
on or while driving¢
fig. 189 and the indica
tor light
[I] in the instrument cluster blinks
f or approximately one minute and then stays
on, there is a system malfunction . See your
authorized Audi dealer as soon as possible.
A WARNING
-- If the tire pressure indicator appears in
the instrument cluster display, one or more of your tires is significant ly under
inflated. Reduce you r speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In
flate the tire pressure to the proper pres-
sure as indicated on the vehicle's tire .,..
