—Do not use run-flat tires on
your vehicle. Using them when
not permitted can lead to ve-
hicle damage or accidents.
—If you install wheel covers on
the vehicle, make sure they al-
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.

Tire wear
Check the tires regularly for wear.
—Inflation pressure that is too low
or high can increase tire wear
considerably.
—Driving quickly through curves,
rapid acceleration, and heavy
braking increase tire wear.


) Obey any applicable regulations in the
country where the vehicle is being oper-
ated.
222
—Have an authorized Audi dealer
or authorized Audi Service Facili-
ty check the wheel alignment if
there is unusual wear.
—Have the wheels rebalanced if an
imbalance is causing noticeable
vibration in the steering wheel.
If you do not, the tires and other
vehicle components could wear
more
quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are
1/16 in (1.6 mm) high and are
spaced evenly around the tire per-
pendicular to the running direc-
tion > fig. 178. The letters “TWI”
or triangles on the tire sidewall
indicate the location of the tread-
wear indicators.
The tires have reached the mini-
mum tread depth )) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones > A.

increase the risk of the loss of
vehicle control.
—The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
—Tires on a vehicle that has
been overloaded can fail sud-
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
—Always make sure that the to-
tal load being transported
does not make the vehicle
heavier than the vehicle’s
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu-
late the total weight of the pas-
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload-
ed.

Steps for Determining Correct
Load Limit
1. Locate the statement “THE
COMBINED WEIGHT OF OCCU-
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS” on your vehicle’s placard
(tire inflation pressure label)
> page 223, fig. 180.
. Determine the combined
weight of the driver and pas-
sengers that will be riding in
your vehicle.
. Subtract the combined weight
of the driver and passengers
from “XXX” kilograms or “XXX”
pounds shown on the sticker
> page 223, fig. 180.
. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex-
ample, if the “XXX” amount
equals 1400 lbs. and there will
be five 150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) = 650
lbs.)
. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex-
ceed the available cargo and
luggage load capacity calculat-
ed in Step 4.
. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your

Care and cleaning


follow the instructions from the car wash
operator.
—To reduce the risk of cuts, protect yourself
from sharp metal components when wash-
ing the underbody or the inside of the wheel
housings.
— After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. This in-
creases the risk of an accident. The brakes
must be dried with a few careful brake appli-
cations.

@) Note
— If you wash the vehicle in an automatic car
wash, you must retract the extendable rear
spoiler* if necessary, and fold the exterior
mirrors in to reduce the risk of damage.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
—To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight.
—To reduce the risk of damage, do not wash
decorative decals* with a pressure washer.
—To reduce the risk of damage, do not wash
the power top with a pressure washer.
—To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges, or similar items.
— When washing matte finish painted vehicle
components:
— To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
— Never use protective wax. It can destroy
the matte finish effect.
— Do not place any stickers or magnetic
signs on vehicle components painted with
matte finish paint. The paint could be
damaged when the stickers or magnets
are removed.
@) For the sake of the environment
Only wash the vehicle in facilities specially de-
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.

must be removed before installing the wheel.

Z\ WARNING
— Read and follow the important information
and notes under > page 220.
— Never use the hex socket in the screwdriver
handle to tighten the wheel bolts. Using the
hex
socket will not achieve the required
tightening torque, which increases the risk
of an accident.

@) Note
When removing or installing the wheel, the
rim
could hit the brake rotor and damage the
rotor. Work carefully and have a second per-
son help you.
Unidirectional tires
A unidirectional tire profile is identified by arrows
on the tire sidewall that point in the running di-
rection. You must always maintain the specified
running direction. This is necessary to ensure the
tire's optimal performance in regard to adhesion,
running noise, and friction, and to reduce the risk
of
hydroplaning.
To benefit fully from the advantages of the uni-
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.

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 locking bolts on the battery cells must
be tightened securely.
— Keep ignition sources (open flames, burning
cigarettes, etc.) away from the vehicle bat-
teries to reduce the risk of an explosion.
— 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.
@) 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-
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.
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.

ZX 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
emergency release before towing the vehi-
cle > page 86.
— Follow the local legal regulations for tow-
ing.
Read and follow the important information under
=> page 249.


Preparations
> Only secure the towing cable or tow bar at the
designated towing loops > page 250,
=>page 251.

>» Make sure the towing cable is not twisted. Oth-
erwise it could disconnect from the towing loop
while towing.
> Switch the emergency flashers on in both
vehicles > page 38. However, do not do this if it
prohibited by law.
Towing vehicle (front)
> Only start to drive when the towing cable is
taut.
> Be especially careful when accelerating.
» Avoid sudden braking or driving maneuvers.
Vehicle being towed (rear)
> Make sure the ignition is switched on so that
the steering wheel is not locked and so that you
can use the turn signals, the horn, and the
windshield wipers if needed > /A\.
> Switching it off before the vehicle has stopped
may impair the function of the brake booster
and power steering. You would then need to
use more force to steer and brake the vehicle.
> Release the parking brake > page 77.
> Select the “N” selector lever position.
> Make sure the towing cable is always taut.
