Checking and Filling

@) Note
— The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions and the climate. A concentration
that is too high can lead to vehicle damage.
— Never add radiator anti-freeze or other addi-
tives to the washer fluid.
— Do not use a glass cleaner that contains
paint solvents, because this could damage
the paint.
Service interval display
The service interval display detects when your ve-
hicle is due for service.
The service interval display works in two stages:
— Inspection or oil change reminder: after a cer-
tain distance driven, a message appears in the
Infotainment system display each time the ig-
nition is switched on or off. The remaining dis-
tance or time is displayed briefly.
— Inspection or oil change due: if your vehicle
has reached an inspection or oil change interval
or both intervals at the same time, the mes-
sage Inspection due! or Oil change due! or Oil
change and inspection due! appears briefly af-
ter switching the ignition on/off.
Checking service intervals
You can check the remaining distance or time un-
til the next oil change or next inspection. Select
in the Infotainment system: the [MENU] button >
Vehicle > left control button > Service & checks >
Service intervals.


Resetting the indicator
An authorized Audi dealer or authorized Audi
Service Facility will reset the service interval dis-
play after performing service.
If you have changed the oil yourself, you must re-
set the oil change interval.
To reset the display, select in the Infotainment
system: the [MENU] button > Vehicle > left con-
trol button > Service & checks > Service intervals
> Reset oil change interval.



CG) Note
— Only reset the oil change indicator if the oil
was changed.
— Following the service intervals is critical to
maintaining the service life and value of
your vehicle, especially the engine. Even if
the mileage on the vehicle is low, do not ex-
ceed the time for the next service.

Tires and vehicle load limits
There
are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al-
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.

Your safety and that of your pas-
sengers also depends on making
sure that load limits are not ex-
ceeded. Vehicle load includes ev-
erybody and everything in and on

installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Applies to: vehicles with tire pressure monitoring system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the tem-
perature and pressure in the tires. The data is
sent from these sensors to the control module by
radio frequency.
The tire pressure monitoring system shows the
current pressures and temperatures of the tires
in the Infotainment system while driving
= page 259. It also compares the current tire
pressures with the stored tire pressures and gives
a warning if the tire pressure is different from
what is stored > page 260.
The system does not detect if the stored tire
pressures match the recommended tire pres-
sures. You must store the tire pressures again in
each of the following situations > page 260:
— Each time the tire pressures change, for exam-
ple when the load in the vehicle changes
— After replacing a tire
— If wheels with new wheel sensors are used

Z\ WARNING
— The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
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.
— A tire 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.
@ 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.
— For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
=> page 283.
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.

— Green: the current tire pressure and the speci-
fied tire pressure are approximately the same.
— Yellow: the current tire pressure is lower than
the specified tire pressure.
The specified tire pressure is the last tire pressure
that was stored > page 260.
Note that the tire pressure also depends on the
temperature of the tire. The tire pressure increas-
es as the engine becomes warmer while driving.

nated mounting point.
> Align the vehicle jack so the arm (@) engages in
the designated mounting point in the side sill
and the base (2) lies flat on the ground. The
base (2) must be directly under the mounting
point @).
> Continue raising the vehicle jack until the wheel
lifts off the ground slightly.


— Make sure the vehicle jack is stable. There is
a risk of injury when the ground is slippery
or soft, because the vehicle jack could slide
or sink.
— Only raise your vehicle with the vehicle jack
provided by the factory. If you use a vehicle
jack designed for another vehicle, your vehi-
cle could slip and cause injury.
— Position the vehicle jack only at the desig-
nated mounting points on the side sill and
align the jack. Otherwise, the vehicle jack
could slip and cause an injury if it does not
have sufficient hold on the vehicle.
—To reduce the risk of injury, do not raise any
other vehicles or other loads using the vehi-
cle jack provided by the factory.
—To reduce the risk of an accident, never start
the engine when the vehicle is raised.
—To reduce the risk of injury, support the vehi-
cle securely with suitable stands if work is to
be performed underneath the vehicle.


Z\ WARNING
—To reduce the risk of injury, make sure no
one is in the vehicle before raising it.

272
@) Note
Do not lift the vehicle by the sill. Position the
vehicle jack only at the designated mounting
points on the side sill. Otherwise, your vehicle
could be damaged.

Emergency assistance

> The wheel bolt tightening specification must be
90 ft lbs (120 Nm). Have it checked as soon as
possible with a torque wrench. Drive carefully
until then.
> Have the faulty wheel replaced as quickly as
possible.
Spare tire
General information
Applies to: vehicles with space-saving spare tire (compact
spare tire)
—maa
BFV-0166

The spare tire is intended for short-term use only.
Have the damaged tire checked and replaced if
necessary by an authorized Audi dealer or author-
ized Audi Service Facility as soon as possible.
There are some restrictions on the use of the
compact spare tire. The compact spare tire has
been designed specifically for your type of vehi-
cle. Do not replace it with the spare tire from an-
other type of vehicle.
Removing the spare tire
> Turn the handle > fig. 197 @ counter-clock-
wise.
>» Remove the spare tire.
Removing the vehicle jack
> Lift up the cover on the right side of the lug-
gage compartment and remove the vehicle
jack.
Snow chains
For technical reasons, the use of snow chains on
the
compact spare tire is not permitted.
If you have to drive with snow chains and a front
tire fails, mount the spare tire in place of a rear
274

tire. Install the snow chains on the rear tire that
you removed, and install that in place of the
front tire that failed.

Z\ WARNING
— After installing a spare tire, the tire pressure
must be checked as soon as possible.
— Do not drive faster than SO mph (80 km/h)
with a compact spare tire. Driving faster
than that increases the risk of an accident.
— To reduce the risk of an accident, avoid hard
acceleration or braking and driving fast
around curves with the compact spare tire.
— To reduce the risk of an accident, never drive
with more than one compact spare tire.
— Normal summer or winter tires must not be
mounted on the compact spare wheel rim.

Towing
General information
You should only perform the steps that follow if
you have the necessary tools and technical ex-
pertise.
Towing requires a certain amount of practice. Au-
di recommends contacting a towing company to
have the vehicle transported.
You should only have your vehicle towed by an-
other vehicle when disabled in exceptional cir-
cumstances. Inexperienced drivers should not
tow.
Notes on towing
When the engine is stopped, the transmission
will not be sufficiently lubricated if traveling at
high speeds and long distances:
— The maximum permitted towing speed is 30
mph (50 km/h).
— The maximum permitted towing distance is 30
miles (50 km).
Additional information on towing with a tow
truck
The vehicle may only be towed with the front axle
raised. Do not wrap any chains or cables around
the brake lines.

8S8012721BA
Emergency assistance

If the vehicle should be towed with the axle
raised, then the ignition must be switched off to
reduce the risk of damage to the drivetrain.
Tow bar and towing cable
The vehicle can be towed with a tow bar or tow-
ing cable. Both drivers should be familiar with
the special considerations when towing, especial-
ly when using a towing cable.
Always make sure the traction force does not ex-
ceed the permitted level and there are no shock
loading conditions. There is always the risk of the
coupling becoming overloaded when driving off-
road.
For the most safety and security, drive with a tow
bar. You should use a towing cable only if a tow
bar is not available. Use a towing cable made of
synthetic elastic cable similar elastic material.

ZA\ WARNING
— Towing highly increases the risk of an acci-
dent, for example from colliding with the
towing vehicle.
— To reduce the risk of an accident, do not al-
low anyone to remain inside the vehicle
when it is being transported by a tow truck
or a special transporter.

@) Note
— If normal towing is not possible, for exam-
ple if the transmission is faulty or if the
towing distance is greater than 30 miles
(50 km), then transport the vehicle on a
special carrier.
— If the vehicle is towed by a tow truck at the
axle that is not permitted, this can cause se-
vere damage to the transmission.
— The vehicle must not be tow started for
technical reasons.
@) Tips
—If there is a power failure, the selector lever
will not move out of the "P" position. The
parking lock must be released using the
