—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 297.
Disp Rte eee See ed
Applies to: vehicles with tire pressure monitoring system
Requirement: you must be driving the vehicle.
> Applies to MMI: Select on the home screen: VE-
HICLE > Settings & Service > Tire pressure
monitoring > Display tire pressure.
The current tire pressures are shown in green,
yellow, or red numbers:
— 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.
— Red: the current tire pressure is much lower
than the specified tire pressure.
The specified tire pressure is the last tire pressure
that was stored > page 265.
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.

Z\ WARNING
Read and follow the important information
and notes > page 264.
@ 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.
(1) Tire pressure loss
Applies to: vehicles with tire pressure monitoring system
If the @ indicator light turns on, the tire pres-
sure is too low compared to the specified pres-
sure. Check and store the tire pressure(s) the
next time it is possible > page 265.
@® Flat tire! Safely stop vehicle. Please check all
tires and store pressures in MMI
If the indicator light turns on and the message
appears, the tire pressure has reached a critical
level compared to the specified pressure. Avoid
unnecessary steering and braking maneuvers.
Adapt your driving style to the situation. Stop as
soon as possible and check the tire(s). If it is pos-
sible to continue driving, see an authorized Audi
dealer or authorized Audi Service Facility immedi-
ately and have your tire(s) repaired or replaced.

ZA WARNING
Read and follow the important information
and notes > page 264.
Storing new tire pressures
Applies to: vehicles with tire pressure monitoring system

The tire pressure specifications must be stored
correctly for the tire pressure monitoring system
to function reliably.
It is always necessary to store the tire pressures
when the tire pressures are modified, for exam-
ple due to a change in load or when new sensors
are installed.
> Before storing the tire pressures, make sure the
tire pressures of all four tires meet the speci-
fied values and are adapted to the load
=> page 254, fig. 176. Only correct and store
the pressure in tires whose temperature is ap-
proximately the same as the ambient tempera-
ture. If the temperature of the tire is higher
than the ambient air temperature, the tire
pressure must be increased approximately
3 PSI (0,2 bar) above the value on the sticker.
> Switch the ignition on.

Raising the vehicle

Applies to: vehicles with vehicle jack


B8W-0193


Fig. 184 Sill: positioning the vehicle jack
> Place the vehicle jack from the vehicle tool kit
ona firm surface. Use a flat, stable support if
necessary. On a slippery surface such as tile,
you should use a non-slip pad such as a rubber
mat > /\.
> Find the marking on the sill that is closest to
the tire that will be changed > fig. 183. Behind
the marking, there is a lifting point on the side
sill for the vehicle jack.
> Turn the handwheel to raise the vehicle jack un-
der the lifting point on the side sill until the
bracket on the jack @) completely covers the
notch on the vehicle.
> Align the vehicle jack so the bracket (@) covers
the notch and the base (2) is flat on the ground.
The base (2) must be directly under the mount-
ing point @.
> Mount the crank on the vehicle jack: insert the
crank into the opening on the handwheel. Turn
the crank to the left or right to secure it.
> Continue raising the vehicle jack with the crank
until the wheel lifts off the ground slightly.
278

AN WARNING
—To reduce the risk of injury, make sure no
one is in the vehicle before raising it.
— Make sure the vehicle jack is stable. The risk
of injury is increased 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, no work should
be performed under the vehicle while it is
raised.

() 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

> Reinstall the caps on the wheel bolts if necessa-
ry.
> Store the vehicle tool kit in its designated
place.
> If the removed wheel does not fit in the spare
wheel well, store it securely in the luggage
compartment > page 92.
> Check the tire pressure on the installed wheel
as soon as possible.
> Correct the tire pressure and store it in the MMI
=> page 263 or > page 265.
> 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.
Space-saving spare tire
Applies to: vehicles with space-saving spare tire (compact
spare tire)
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.
The compact spare tire is located in the luggage
compartment under the cargo floor cover
=> page 274.
The tire pressure must be adjusted to a specified
value listed on the tire pressure sticker
= page 254, fig. 176.
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
tire. Install the snow chains on the rear tire that
280
you removed, and install that in place of the
front tire that failed.

ZA\ WARNING
— After installing a spare tire, the tire pressure
must be checked as soon as possible.
—Do not drive faster than 50 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.
@) Note
Secure the spare tire in the spare tire well us-
ing
the handwheel in order to reduce the risk
of damage to other components.

Jump starting
You should only perform the steps that follow if
you have the necessary tools and technical ex-
pertise.
If the engine does not start because the vehicle
battery is drained, you can jump start your vehi-
cle using another vehicle. Jump start cables are
needed to do this.
Both vehicle batteries must have 12 V nominal
voltage. The voltage capacity (Ah) of the vehicle
battery that is giving power must not be less
than the capacity of the drained vehicle battery.
Jump start cable
Only use a jump start cable with a large enough
diameter. Note the manufacturer's specifica-
tions.
Only use a jump start cable with insulated termi-
nal clamps.
Positive cable - usually red.
Negative cable - usually black.

Emergency assistance


ZA WARNING
— A drained battery can freeze at tempera-
tures around 32 °F (0 °C). If the vehicle bat-
tery is frozen, it must be thawed before con-
necting the jump start cables. If it is not,
the risk of an explosion and chemical burns
increases. After jump starting the vehicle,
drive to an authorized Audi dealer or author-
ized Audi Service Facility immediately to
have the vehicle battery checked.
— Read the warnings when working in the en-
gine compartment > page 230.
— Handling the jump start cables incorrectly
may cause the vehicle battery to explode
and lead to serious injuries.

() Note
Jump start cables can cause considerable
damage to the vehicle electrical system if
they are connected incorrectly.
@ Tips
— There must be no contact between the
vehicles, or else voltage could flow when
connecting the positive terminal and drain
the vehicle battery of the vehicle providing
the jump start.
— The drained vehicle battery must be con-
nected correctly to the electrical system.
— Switch off electrical equipment that is not
needed.
Both jump start cables must be connected in the
correct order.

Emergency assistance

> With the engines running, remove the cables in
reverse order of the way they were installed.
> Close the cover on the positive terminal.

ZA WARNING
— Never connect the jump start cable directly
to your vehicle battery. Only use the connec-
tions in the engine compartment.
— Do not touch the non-insulated parts of the
terminal clamps. The cable must also not
come into contact with vehicle components
that conduct electricity when it is connected
to the positive vehicle battery terminal. This
can cause a short circuit.
— The plugs on the battery cells must not be
opened.
— Keep ignition sources (such as open flames,
burning cigarettes, etc.) away from the vehi-
cle batteries to reduce the risk of an explo-
sion.
— Route the jump start cables so they cannot
get caught in the moving parts in the other
vehicle's engine compartment.

@) Note
Please note that the connecting process previ-
ously described for the jump start cables is in-
tended for when your vehicle is being jump
started.
G) Tips
Make sure that the connected jump start ca-
bles have sufficient contact with metal.
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.
Audi 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-
282
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.
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
