Deactivating the convertible locking
retractor
The convertible Locking retractor for child re­
straints will be deactivated automatically when
the belt is wound all the way bock into the re­
tractor .
~ Press the red button on the safety belt buckle.
Th@ belt tongue will pop out of the buckle.
~ Guide the safety belt all the way back into its
stowed position .
Always let the safety belt retract completely into
its stowed position . The safety belt can now be
used as an ordinary safety belt without the con­
vertible locking retractor for child restraints .
If the convertible locking retractor should be ac­
tivated inadvertently, the safety belt must be un­
fastened and guided completely back into its
stowed position to deactivate this feature. If the
convertible lock ing retractor is not deactivated,
the safety belt will gradually become tighter and
uncomfortable to wear.
A WARNING
-
Improperly installed child safety seats in­
crease the risk of serious personal injury and
death in a collision.
- Never unfasten the safety belt to deactivate
the convertible locking retractor for child re­ straints while the vehicle is moving . You

LATCH system (Lower
anchorages and tethers
for children)
' Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicable way to
attach the child restraint on the vehicle seat, Federal regulations require special lower ancho­
rages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages .
In the United States, the combination of the
tether anchorages and the lower anchorages is
now generally called the LATCH system for
"Lower Anchorages and Tethers for Children" . In
Canada, the terms "top tether" with "lower uni­
versal anchorages" (or "lower universal anchor­
age bars") are used to describe the system .
In other countries the term "ISOFIX" is used to
describe the lower anchorages .
Forward-facing child restraints manufactured af­
ter September 1, 1999, are required by U.S. fed­
eral regulations to comply with new child head
movement performance requirements . These
new performance requirements make a tether
necessary on most new child seats.
Installing a child restraint that requires a top
tether without one can seriously impair the per­
formance of the child restraint and its ab ility to
protect the child in a collision. Installing a child
restraint that requires a top tether without the
top tether may be a violation of state law.
Child restraint manufacturers offer LATCH lower
anchorages on their child seats with hook-on or ...

Child safety
Please remember that the lower anchorage
points are only intended for installation and at­
tachment of child restraints specifically certified
for use with
LATCH lower anchorages. Child re­
straints that are not equipped with the lower an­
chorage attachments can still be installed in
compliance with the child restraint manufactur­
er's instructions on using vehicle safety belts .
A WARNING
Improper use of LATCH lower anchorages can
cause serious personal injury in an accident.
- Always carefully follow the child restraints
manufacturer's instructions for proper in­
stallation of the child restraint and proper
use of the lower anchorages or safety belts
in your vehicle.
- Never secure or attach any luggage or other
items to the
LATCH lower anchorages.
- Always read and heed the important infor­
mation about child restraints in this chapter
and WARNINGS

crease the risk of serious personal injury and
death in an accident .
- These anchors were developed only for child safety seats using the "LATCH" system.
- Never attach other child safety seats, belts
or other objects to these anchors .
- Always make sure that you hear a click when
latching the seat in place. If you do not hear
a click the seat is not secure and could fly
forward and hit the interior of the vehicle,
or be ejected from the vehicle.
A WARNING
Improper installation of child restraints will
increase the risk of injury in an accident.

Checking the engine coolant level
• Park your vehicle on a level surface .
• Switch the ignition off .
• Read the coolant level on the coolant expansion
tank
¢ fig. 198 . The coolant level must be be­
tween the markings when the engine in cold .
When the engine is warm it can be slightly above the upper marking.
Adding coolant
Plug-in hybrid drive*: your vehicle has two cool­
ant expansion tanks that are separate from each
other. The smaller of the two expansion tanks
must not be opened
¢ page 108. Read and fol­
low the important safety precautions ¢
A in
Coolant on page 109.
Requirement: there must be a residual amount of
coolant in the expansion tank ¢(D .
• Let the engine cool down .
Checking and Filling
• Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
¢ A .
• Add coolant mixed in the correct ratio
¢
page 244 up to the upper marking.
• Make sure that the fluid level remains stable.
Add more coolant if necessary.
• Close the cap securely .
A coolant loss suggests a leak. Immediately drive
your vehicle to an authorized Audi dealer or au ­
thorized Audi Service Facility and have the cool­
i ng system inspected. If the cooling system is not
leak ing, a loss can come from the coolant boiling
through overheat ing and being pushed out of the
cooling system .
,&_ WARNING
-= -The cooling system is pressurized and can be­
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
with the engine hot. There is a risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coo lant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex ­
haust system or hot engine components.
The ethylene glycol in engine coo lant can
catch fire under certain circumstances .
- The coolant additive and the coolant can be
dangerous to your health . For th is reason,
keep the coolant in the original container
away from children. There is a risk of poi­
soning .
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, wh ich
increases the risk of persona l injury.
