the ignition is switched on . To prevent engine
damage, please observe the following notes
about the temperature ranges.
Cold range
If onl y the L EDs at the bottom o f th e ga uge turn
on, the engine has not reached operating tem­ pe rature yet. Avoid high engine speeds, full ac ­
cele rat ing and heavy engine loads.
Normal range
The engine h as reached its oper ating temper a­
ture once the LEDs up to the center o f the ga uge
turn on. If

bra ke fluid level in the reservoir is too low ,
and this inc reases the risk of an acc iden t.
Stop the vehicle and do not continue dr iv ­
ing. See an authorized Audi dealer or au­
tho rized Audi Service Facility for ass istance .
- If the bra ke sys tem indicator light turns on
together with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
be malfunctioning. Functions that stabilize
the vehicle are no longer ava ilable. This

Driving
_& WARNING
-Never turn off the engine before the vehicle
has come to a complete stop. The full func­
t ion of the brake booster and the power
steering is not guaranteed. Yo u must use
more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and ser i­
ous injuries.
- Never remove the ignit ion key from the ign i­
tion lock while the vehicle is moving. Other ­
wise, the steering lock cou ld sudden ly en­
gage and you would not be able to steer the
vehicle.
- Always take the key with you whenever you
leave your vehicle. Otherw ise, the engine
could be started or electrical equipment
suc h as the power windows could be operat­
ed . This can lead to serious injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position .
Otherwise, there is the r isk that the vehicle
could roll unintentionally.
(D Note
If the engine has been under heavy load for
an extended per iod of t ime, heat builds up in
the engine compartment after the engine is
sw itched off and there is a risk of damaging
the engine. For this reason, let the engine run
for at idle for approximately two minutes be­
fore shut ting it off.
(0 Tips
For up to 10 minutes after stopping the en­
gine, the rad iator fan may turn on again auto­
matically or it may continue to run (even if
the is ignition switched off) due to the follow­
ing reasons:
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun ­
light.

tires to trailer and tire manufacturers' specifica­
tions.
Lights
Check to make sure both vehicle and trailer lights
are working p roperly.
Safety chains
Be sure trailer safety chains are properly connect ­
ed from the tra iler to the hitch on the vehicle.
Leave enough slack in the chains to permit turn­
in g corners . When you install safety cha ins, ma ke
sure they w ill not drag on the road when yo u are
driving .
The chains shou ld cross under the trailer tongue
to prevent it from dropping in case of separat ion
from the hitch.
Driving instructions
Driving with a trailer always requires extra care
and consideration.
Weight distribution
Towing a loaded trailer w ith an empty car results
in a highly unstable distribution of weight . If this
cannot be avo ided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keep ing the tra iler as light as possib le under the
circumstances. Whenever possib le, t ransfer
some cargo to the luggage compartment of the
tow vehicle whi le observing tongue load require­
ments and vehicle loading considerations .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
conditions are unfavorable
-particu larly when
going downhill.
Reduce vehicle speed
immediately if the trailer
shows the s lightest sign of swaying .
Do not try
to stop the swaying by accelerating.
Tra iler towing
Observe speed limits. In some a reas, speeds for
vehicles towing trailers are lower than for regular
vehicles .
Always apply brakes early. When driving down­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fa il.
Coolant temperature
T he coo lant tempe rature gauge ~ page 11 must
be observed carefully . The coolant temperature
can increase if you drive on long inclines in a low
gear at high engine speeds. Reduce your speed
immediately if the LEDs in the top part of the dis­
play turn on.
For more information about indicator lights, re­
fer
to . ~page 28.
A WARNING ,-
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Aud i.
Trailer towing
information
Important to know
Your vehicle handles differently when towing a
trailer because of the addit ional weight and dif­
ferent weight distribution . Safety, performance
and economy will g reatly depend on how careful­
ly you load your trailer and operate yo ur rig.
Before you actually tow your trailer, pract ice
turning, stopping and backing up in an area away
from traffic. Keep practic ing until you have be­
come complete ly familiar w ith the way your vehi­
cle-trailer combination behaves and responds.
Backing up is difficult and requires practice.
Backing up with a t railer genera lly requires steer ­
i ng action opposite to that when backing up your
vehicle without a tra iler.
Maintain a greater distance between your vehicle
and the one in front of you. You will need more
.,,.

Checking and Filling
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 104. Read and fol­
low the important safety precautions ¢
A in
Coolant on page 105 .
Requirement: there must be a residual amount of
coolant in the expansion tank
¢ (D .
~ Let the engine cool down.
~ Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
¢_&. .
~ Add coolant mixed in the correct ratio
¢page 323 up to the upper marking.
~ Make sure that the fluid level remains stable.
Add more coolant if necessary.
~ Close the cap securely.
Coolant loss usually indicates there is a leak . Im­
mediately 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, a loss can come
from the coolant boiling through overheating
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
when the engine is hot. This increases the
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
coolant 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.
324
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children . There is a risk of
poisoning.
- 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.
(D 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.
- Before the start of winter, have an author­
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage the en­
gine. If this happens, only use water and re­
store the correct mixture ratio with the
specified coolant additive as soon as possi­
ble .
- Only refill with new coolant.
- Radiator sealant must not be mixed with the coolant.
· Radiator fan
The radiator fan switches on automatically by it­
self
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes
-even
with the ignition off.
It can even switch on again
later by
itself ¢.& , if .,..

- the temperature of the engine coolant r ises due
to the heat bui ld-up from the engine in the en­
gine compartment , or
- the engine compartment heats up because the
vehicle is parked in intense su nlight .
_& WARNING
- To reduce the risk of personal injury never
touch the radiator fan .
- The auxiliary elect ric fan is temperature
contro lled and can switch on suddenly even
w hen the eng ine is not running.
- The auxiliary radiator fan switches on auto­ matically when the engine coo lant reaches a
certain temperature and will cont inue to run
until the coolant temperat ure drops.
