198 Trailer towing
Trailer towing tips
Important to know
Your vehicle hand les different ly when tow ing
a trailer because of the addit ional 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 veh icle-trailer combination behaves and
responds.
Backing up is difficult and requires practice.
Backing up with a trai ler generally 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
turning 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
in g lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a tra iler dur ing 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 2 72.
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.
.. Tur n the wheels towards the curb.
.. App ly the parking b rake.
.. 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/S, 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.

tire and the pressure you need and add the a ir
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your vehicle as listed on the on
your veh icle and in this manual and the kind
of dr iving you plan to do .
Never ex ceed the ma ximum infl ation pres­
su re list ed on the t ire s ide wall for an y rea­
son.
Remember that the vehicle manufacturer, not
the t ire manufacturer, determ ines the correct
tire pressure for the t ires on your vehicle.
It is important to check the tire pressure when
the tires are cold.
- Read the req uired ti re press ure from the tire
pressure label. The tire pressu re labe l is lo­
cated on the drive r's side 8 -p ill ar . The tire
pressure label lists the recommended cold
t ire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­
ufactured . For recommended t ire pressures
for normal load condit ions, please see chap­
ter ¢
page 234.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressure gauge on the valve.
- The tire pressures should only be checked
and adjusted when the tires are cold. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Re install the valve stem cap on the valve.
When should I ch eck th e tir e pre ssure?
The correct tire pressure is especially impor­
tant at high speeds . The pressure should
therefore be checked at least once a month
and always before start ing a journey. Do not
forget to check the tire pressure for the spare
wheel.
Wh en should I adjust th e tire p re ss ures ?
Ad just the tire pressure to the load you are
carry ing . After changing a wheel
or replacing
Tires an d wheel s 237
whee ls you have to adjust the ti re pressu res
on all whee ls. In addition, yo u m ust then initi­
a lize the new tire pressures in the t ire pres­
sure monitoring system*¢
page 248.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the
ti] warning symbol appears in
the instrument cluster, stop and inspect
the t ires.
- Inco rrect tire pressure and/or underinfla­
tion can cause increased tire wear and can affect the handling of the vehicle and
stopping ability.
- Inco rrect tire pressures and/or unde rin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and sudden de­
f lation, caus ing loss of veh icle contro l.
- The drive r is responsib le for the correct
tire pressures for all tires on the veh icle.
The applicable pressure values are locat ­
ed on a sticke r on the driver's side 8-pil­
lar.
- On ly when all tires on the vehicle are fil ­
led to the correct pressure, the tire pres­
sure mon itor ing system* can work cor­
rectly.
- The use of incorrect tire pressu re va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the t ires and the correct pressures for
the function of the t i re p ress ure monito r­
ing system*.
- Always inf late t ires to the recommended
and correct t ire p ressure before dr iv ing
off.
- Driving with unde rinflated tires bend
mo re, lett ing t hem get too hot resulting
in tre ad separation, sudden tire failure
and loss of cont rol.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of cont rol.

248 Tires and wheels
In order to minimize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions :
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add a ir if neces­
sary.
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ir e as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and underinflation, wh ich could event u­
ally cause t ire failure.
If you believe that a
ti re may have been damaged, replace the
tire as soon as possible.
-These tires may wea r more quickly than oth­
ers.
- Please also remember that, while these tires
deliver responsive handling, they may ride
less comfortably and make more noise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes .
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for max imum dry and wet road per­
f ormance and handling . They are not suitable
for cold, snowy or icy weather cond it ions.
If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, which offer better traction under
those conditions . We suggest you use the rec­
ommended snow or all-season tires specified
for your vehicle, or their equiva lent .
Refer to~
page 245 for mo re detailed infor­
mation regarding w inter tires.
Tire pressure
monitoring system
ill General notes
Applies to veh icles: w ith tire pressure monito ring system
Each tire, including the spare (if provided),
shou ld be checked monthly when co ld and in­
flated to the inf lation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
s iz e indicated on the vehicle placard or tire in­
flat io n pressu re label, you shou ld dete rmin e
the proper tire inflation pressure for those
tires) .
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system ( TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significant ly under -inflated . Acco rding­
ly, when the low tire pressure te lltale illumi­
nates, you shou ld stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly un­
der- inflated tire causes the tire to overheat
and can lead to tire fa ilure . Under -inflation al ­
so reduces fuel eff ic iency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's respons ibility to maintain correct tire
pressure, even if under -inflation has not
reached the level to trigger illumination of the
T PMS low tire p ressu re tellta le .
Your vehicle has also been equipped with a
TPMS malfunction indicator to ind icate when
the system is not operating properly . Th e
T PMS ma lfunction indicator is combined with
the low tire pressure telltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximately one minute and then
rema in con tinuously illuminated . Th is se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunct ion exists . .,.
