2015 AUDI A3 CABRIOLET warning

260 Tire s and wheel s
& WARNING
-If the tire pressure warning light ti] in
the instrument cluster turns on, the
pressure in one or more tires is too low.
Reduce the vehicle speed immediately
and avoid any hard steering or braking
maneuvers . Stop as soon as possible,
check the t ire and inflate the tire to the
correct pressure, which is specified on
the tire pressu re labe l on the veh icle
<:?page 235. Driving with a t ire with low
pressure causes the tire to overheat and
can res ult in failure of the tire . Low pres ­
sure can a lso have a negat ive effect on
the driving and braking behavior of the
vehicle.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain cond itions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be de layed .
- Ask your author ized dealer if r un-flat
t ires may be used on your vehicle.
- The tire pressure monitoring system can
also stop work ing when there is an ESC
malfunction.
- Using snow chains may result in a system
malfunction.
- The tires with the ident ificat ion "AO" or
"RO" ¢ page 248 have been matched
with your A udi tire pressure monitoring
system. We recommend that you use
these tires.
- The tire pressure monitoring system can
on ly mon itor the t ire pressure of the
driving tires . Check the tire pressu re of
the spa re wheel in the luggage com part­
ment so tha t if ne cessary i t is ready for
u se.

int ended fo r use in a specific dir ection
When us ing a spare tire w ith a tread pattern
i ntended for use in a specific direction, please
note t he following:
- The direction of rotation is marked by an ar ­
row on the side of the tire .
-If the spare t ire has to be installed in the in­
correct direction, use the spare tire only
temporarily since the t ire will not be able to
achieve its optimum perfo rma nce character­
ist ics with rega rd to aquaplaning, noise and
wea r.
- We recommend that you pay particular at­
tent ion to this fact du ring wet weat her and
that you adjust your speed to match road
