Glossary of tire and loading
terminology
Accessory weight
means the combined weight ( in
excess of those standard items
which may be replaced) of auto­ matic transmission , power steer ­
ing, power brakes, power win­
dows, power seats, radio, and
heater, to the extent that these
items a re available as factory- in­
stalled equipment (whether i n­
stalled or not) .
Aspect ratio
means the ratio of the height to
the width of the tire in percent .
Numbers of 55 or lower indicate a
low s idewall for improved steer­
ing response and better overall
handling on dry pavement.
Bead
means the part of the tire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim .
Bead separation
means a breakdown of the bond
between components in the bead .
Wheel s
Cord
means the strands forming the
plies in the tire .
Cold tire inflation pressure
means the tire pressure recom­
mended by the vehicle manufac ­
turer for a tire of a designated
size that has not been driven for
more than a couple of miles (kilo­
meters) at low speeds in the
three hour period before the tire pressure is measured or adjusted .
Curb weight
means the weight of a motor ve­
hicle with standard equipment in­
cluding the maximum capacity of
fuel, oil , and coolant, air condi­
tioning and additional weight of
optional eq uipm ent .
Extra load tire
means a tire designed to operate
at higher loads and at highe r in­
flation pressures than the corre­
sponding standard tire . Extra load
tires may be identified as "X L",
"xl", "EXTRA LOAD", or "RF" on
the sidewall.

-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­
ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side B­
pillar, always follow the specifica­
tion on the B-pillar label

negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
@ Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­ creases fuel consumption.
Make sure that the tire designa­
tion on your tire matches the des­
ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­ mended tire pressures in cold
tires according to the load and
the size of the tires installed.

vehicle's Gross Veh ic le Weig ht
R ati ng
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs . (68 kg) for each passen­
ger at a designated seating posi ­
tion and the total weight of any luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load .
The
Gro ss Ax le W eight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles .
T he fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited . The more pas­
sengers in the vehicle or passen -
344
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage .
The Gross Vehicle Weight Rating and the Gross Axle Weight Rat ing
are listed on the safety compli­
ance sticker labe l located on the
driver's side B-pillar.
1.8. WARNING
Overloading a vehicle can cause loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and 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 contro l and a crash.
-Always make sure that the to­ tal load being transported

Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
~ Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Jump starting
Preparation
If needed, the engine can be jump started by an­
other vehicle battery.
Applies to: vehicles with plug-in hybrid drive: the
connection points for the jump start cable are
different
q page 102.
If the engine does not start because the vehicle
battery is drained, you can jump start the engine
using another vehicle battery. You need a jump
start cable 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 situations
A WARNING
--
- Applies to: vehicles with plug-in hybrid
drive: you must
not give a jump start with
your vehicle . This could cause significant
damage to the electrical system in your ve­
hicle
Q page 102.
-A drained vehicle battery can freeze at tem­
peratures around 0
Q(. If the vehicle battery
is frozen, you must thaw it before connect­
ing the jump start cables. If you do not, this
increases the risk of an explosion and chem­
ical burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­
ized Audi Service Facility immediately to
have the vehicle battery checked.
- The engine compartment is a dangerous
area and can cause serious injuries. Before
working in the engine compartment, read
and follow the warnings
Qpage 318.
- Handling the jump start cables incorrectly
may cause the vehicle battery to explode
and lead to serious injuries . To reduce the
risk of injury, observe the following:
- 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 terminal. This can cause a
short circuit.
- Route the jump start cables so they cannot
get caught in the moving parts in the engine
compartment.
- To reduce the risk of chemical burns, do not
bend over the vehicle battery.
- 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.
- Do not clamp the negative cable to fuel sys­ tem components or to the brake lines.
(LlJ} Note
- There must be no contact between the
vehicles, If there is, current could already be
