Checking the engine coolant level
>» Park the vehicle on a level surface.
> Switch the ignition off.
> Read the coolant level on the coolant expansion
tank > page 230, fig. 174. The coolant level
must be between the markings @) 9 fig. 177
when the engine is cold. When the engine is
warm it can be slightly above the upper mark-
ing.
Adding coolant
Requirement: there must be a residual amount of
coolant in the expansion tank >@.
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
> Allow the engine to cool.
>» Place a large, thick towel on the coolant expan-
sion tank cover.
> Remove the cover (@) 9 fig. 177 carefully to the
left > AX.
> Add the correct mixture ratio of coolant
> page 234 up to the upper marking @)
> fig. 177.
> Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Close the cap securely.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the engine
compartment with caution.
— When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.


@) Note
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal-
er or authorized Audi Service Facility for assis-
tance.

Z\ WARNING
— The engine compartment in any vehicle can
be a dangerous area. Stop the engine and al-
low it to cool before working in the engine
compartment. Always follow the informa-
tion found in > page 227, General informa-
tion.
— Never open the hood if you can see or hear
steam or coolant escaping from the engine

information on page 228.
Checking the brake fluid level
> Read the brake fluid level on the brake fluid res-
ervoir > page 230, fig. 174. The brake fluid lev-
el must be between the MIN and MAX markings
oA.
The brake fluid level is monitored automatically.
Changing the brake fluid
Brake fluid should be changed at regular inter-
vals. Have the brake fluid changed by an

windows, power seats, radio, and
heater, to the extent that these
items are available as factory-in-
stalled equipment (whether in-
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 sidewall 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.
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 pres-
sure 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 equipment.
Extra load tire
means a tire designed to operate
at higher loads and at higher in-
flation pressures than the corre-
sponding standard tire. Extra load
tires may be identified as “XL”,
“xl”, “EXTRA LOAD”, or “RF” on
the sidewall.
Gross Axle Weight Rating
(“GAWR”)
means the load-carrying capacity
of a single axle system, measured
at the tire-ground interfaces.
Gross Vehicle Weight Rating
(“GVWR”)
means the maximum total loaded
weight of the vehicle.
Groove
means the space between two ad-
jacent tread ribs.

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

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.
The Gross Axle Weight Rating
(“GAWR’”) is the maximum load
that can be applied at each of the
vehicle’s two axles.
The fact that there is an upper
