Wheels


driver is responsible for having the tires in-
flated to the correct pressure.
— Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, increas-
ing the risk of an accident.
—Atire with low pressure flexes more. This
heats the tire up too much. This could cause
the tread to separate and even cause the tire
to burst, increasing the risk of an accident.
— The tire pressure monitoring system does
not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu-

larly.

(i) Tips
— If tires are replaced, the sensors and valves
do not need to be removed or replaced. Only
replace the valve stem and, if necessary, the
valve and the wheel electronics. If you have
questions, see an authorized Audi dealer or
authorized Audi Service Facility.
— An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors replaced by an authorized Audi
dealer or authorized Audi Service Facility.
— The system complies with United States FCC
regulations and ISED regulations
=> page 267.
Displaying tire pressures and temperatures
Applies to: vehicles with tire pressure monitoring system
Requirement: you must be driving the vehicle.

> Select in the Infotainment system: [MENU] but-
ton > Service & checks > Tire pressure monitor-
ing > Display tire pressure.

The current tire pressures are shown in green,
yellow or red numbers in the Infotainment sys-
tem:
— Green: the current tire pressure and the speci-
fied tire pressure are approximately the same.
234
— Yellow: the current tire pressure is lower than
the specified tire pressure.
— Red: the current tire pressure is much lower
than the specified tire pressure.
The specified tire pressure is the last tire pres-
sure that was stored > page 235.
Note that the tire pressure also depends on the
temperature of the tire. The tire pressure in-
creases as the engine becomes warmer while
driving.

ZA\ WARNING
Read and follow the important information
and notes > page 233.
@ Tips
The tire pressure or temperature is not dis-
played while the vehicle is stationary and in
adaptation mode. Dashes --.-- are shown in
place of the pressure and temperature.
Tire pressure loss
Applies to: vehicles with tire pressure monitoring system

If the @ indicator light turns on, the pressure in
at least one tire is too low or new sensors were
not adapted:
The indicator light turns on after turning the
ignition on
The tire pressure is too low compared to the
specified pressure.
> Check and store the tire pressure(s) the next
time it is possible > page 235.
The indicator light turns on while driving
Wheels with new sensors were not adapted or
the tire pressure has reached a critical level com-
pared to the specified pressure.
> Avoid unnecessary steering and braking maneu-
vers.
> Adapt your driving style to the situation.
> Stop as soon as possible and check the tire(s).
> If it is possible to continue driving, see an au-
thorized Audi dealer or authorized Audi Service
Facility immediately and have your tire(s) re-
paired or replaced if necessary.

Z\ WARNING
Do not repair fuses and never replace a blown
fuse with one that has a higher amp rating.
This can cause damage to the electrical sys-
tem and increases the risk of fire.

CG) Note
If a new fuse burns out again shortly after you
have installed it, have the electrical system
checked as soon as possible by an authorized
Audi dealer or authorized Audi Service Facility.

ing tables applies only to certain model ver-
sions or certain optional equipment.
