tra iler tires to trailer and tire manufacturers'
specif ications.
Lights
Check to make sure both vehicle and t railer lights
are working p roper ly.
Safety chains
Be sure t railer safety chains are properly connect­
ed from the trai le r to the hi tch on the veh icle.
L eave enough sla ck in the cha ins to permi t turn­
ing corners. When yo u install safety chains, ma ke
sure they wi ll not drag on the road when yo u are
driving .

Driving instructions
Driving with a trailer always requires extra care
and consideration .
To obtain t he best poss ible handling of vehicle
and traile r, please note the fo llow ing :
.,. Do not tow a loaded trailer when your car itself
is not loaded.
.. Be especi ally ca ref ul when pass ing othe r
vehicles.
.. Observe speed limi ts .
.. Do not d rive at the maximum permissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge .
Weight distribution
Towing a loaded t railer w ith an empty car res ults
in a high ly unstable distribution of weight . If this
cannot be avoided, drive at very low speeds on ly
to avoid the risk of losing steering control.
A "balanced" rig is easie r to operate and cont rol.
This means that the tow vehi cle should be loaded
to the extent possible and permissible, while
keep ing the tra iler as light as possib le under the
circumstances. Whenever possible, transfer
some cargo to the l uggage compartment of the
128
tow veh icle wh ile observing tong ue load require ­
ments and vehicle loading considerations.
Speed
The higher the speed, the mo re diff icu lt i t be­
comes for the driver to con trol the r ig. Do not
drive at t he maxim um permissible speed. Reduce
you r speed even more if load, weather or wind
con dit ions are unfavorab le - partic ularly when
go ing downh ill.
Reduce vehicle speed
immediately if the trailer
shows the slightest sign of swaying.
Do not try
to stop the swaying by accelerating.
Observe speed limi ts. In some areas, s peeds fo r
vehicles towing trailers are lower than for regular
vehicles .
A lways apply bra kes early. Whe n driving down­
hill, shift in to a lower gea r to use the engine
b raki ng effect to slow the vehi cle. Use of the
brakes alone ca n cause them to over heat and fai l.
Coolant temperature
The coolant temperature gauge 9 page 12 must
be obse rved caref ully. The coolant temperature
c a n incre ase if yo u drive o n long incl ines in a low
gear a t high engine speeds . Red uce your speed
immediately if the LE Ds in the top part of the dis­
play turn on .

A WARNING
-
Anyone not prope rly restrai ned in a moving
vehicle is at a much greate r risk in an acci ­
dent. Never let anyone ride in your car who is
not properly wear ing the restraints provided
by Aud i.
Trailer mode notes
Important to know
Your vehicle handles differen tly when towing a
trailer because o f the additiona l weight and di f­
ferent weight distribution. Safety, performance
and economy will g reatly depend on how caref ul-
l y you load your trai ler and operate you r rig. ..,_

Checking and Filling
CJ) Note
-Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi­
tives with the AdBlue and do not dilute it
with water.
- Only use refill bottles that are approved for your vehicle. Using other systems can cause Ad Blue to leak.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the Ad Blue tank. Do not start
the engine under any circumstances if the
wrong fuel is filled in the tank . There is a
risk of damaging the fuel tank system and
the engine . See an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as possible with a
damp cloth and plenty of cold water. If the
Ad Blue has already crystallized, use warm
water and a sponge. AdBlue residue that is
not removed will crystallize and can damage
the affected surface .
- Do not store the refill bottle in the vehicle.
If it leaks, the escaping Ad Blue could dam­
age the vehicle interior .
- Do not allow Ad Blue to come into contact
with clothing. If there is contact with the
fluid, flush immediately with plenty of wa ­
ter .
(D Tips
-You can obtain refill bottles from an author­
ized Audi dealer or authorized Audi Service
Facility .
- Follow the Ad Blue manufacturer's instruc­
tions for use and storage .
- A permitted refill bottle contains approxi­
mately 1.9 liters of AdBlue .
- Ad Blue can freeze at very low temperatures.
If this happens, the system will not detect
that the Ad Blue was refilled and it will con­
tinue to inform you of the low AdBlue level.
The message turns off as soon as the tank
thaws out again.

Working in the engine compartment
Special care is required if you are working in the
engine compartment
For work in the engine compartment such as
checking and filling fluids, there is a risk of in­
jury, scalding, accidents, and burns. For this
reason, follow all the following listed warnings
and general safety precautions. The engine
compartment is a dangerous area.
¢ .&. .
.8, WARNING
To reduce the risk of injuries, complete the
following steps before opening the hood:
- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
- Place the selector lever in the P position.
- Let the engine cool down.
- Never open the hood when you see that
steam or coolant drips from the engine
compartment- there is a danger of burns!
Wait until no steam or coolant flows out.
- Keep children away from the engine com­
partment.
- Never spill fluids on a hot engine. These flu­
ids (such as the freeze protection contained in the coolant) can catch fire.
- Avoid short circuits in the electrical system,
especially the battery.
- 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 personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm . The
cooling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.

Engine oil
Engine oil specifications
The engine oil used must conform to exact speci­
fications.
The service interval display in the instrumen t
cluster of your vehicle will inform you when it is
time for an oi l change. We recommend that you
have your oi l changed by an authorized Audi Serv­
ice Advisor.
If you have to top off the oil between oil changes,
use the Audi oil quality standard specified in the
table .

Checking and Filling
-To reduce the risk of burns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at least the total amount of oil in your engine .
- Engine oil is poisonous. Keep it well out of
the reach of children .
- Continuous contact with used engine oil is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
CD Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adversely affect your Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
-Before changing your oil, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used engine oil properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station.
Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sealed and generally re­
quires little attention.
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed. The coolant consists of a mixture of
244
specially conditioned water and the manufactur­
er's glycol-based coolant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­ els; 60% for Canadian models). This mixture
both assures the necessary frost protection and
protects metal components in the engine's cool­
ing system from corrosion and scaling. It also
raises the boiling point of the coolant.
Do not reduce the concentration of the coolant in
the summer by adding plain water.
The propor­
tion of coolant additive must be at least 50%
but not more than 60%
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
gine cooling system.
For year-round driving, antifreeze is added at the
factory for temperatures down to:
--31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
~ page 236.
CD Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­ ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold.
If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember:
- We recommend using only coolant addi­
tive Gl2++ or G13 (check the label) for
your vehicle. This coolant additive is avail­
able at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The resulting

.... N

.... I.Cl U"I
.... I.Cl ....
corrosion can cause a loss of coolant and
serious engine damage .
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant . Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Limited Warranty.
Adding coolant

expa nsion tank
Read and follow the WARNINGS before check­
ing anything in the engine compartment
¢ page 236, Working in the engine compart­
ment.
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.

Radiator fan
The radiator fan switches on outomotico/ly by it­
self.
An auxiliary elect ric radiator fan sw itches on and
off depend ing on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fa n
can cont inue runn ing fo r up to 10 minutes -even
with the ignition off . It ca n even switch on again
later by itself¢.&. , if
- the temperature of the engine coolant r ises due
to the heat bu ild -up from the engine in the e n­
gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight .
A WARNING
-To reduce the risk of pe rsonal injury never
touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the eng ine is not running.
- The auxiliary radiator fan switches on auto­
matically when the engine coo lant reaches a
certain tempe rature and w ill cont inue to run
until the coolant temperature drops.

today's automobiles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by vehicle owners.
Also, safety and
environmental
concerns place very strict limits
on the n ature of repairs and adjustments to en­
gine and transmission parts which an owner can perform .
Maintenance, adjustments and repairs usually re­
quire special tools, testing devices and o ther
equipment available to specially trained work ­
shop personnel in order to assure proper per­
formance, reliability and safety of the vehicle and
its many systems.
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for upholding a possible warranty claim made within
the warranty period.
Above all , operational safety can be adversely af­
fected, creating unnecessary risks for you and
your passengers.
If in doubt about any servicing, have it done by
your authorized Audi dealer or any other properly equipped and qualified workshop. We strongly urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte­ nanc e and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly .
Performing limited maintenance yourself
The following pages describe a limited number of
procedures which can be performed on your vehi­
cle with ordinary tools, should the need arise and
trained personnel be unavailable. Before per­
forming any of these procedures, always thor­
oughly read all of the applicable text and careful­ ly follow the instructions given . Always rigorously
observe the
WARNINGS provided .
Before you check anything in the engine com-
,.., partment, always read and heed all WARNINGS

A WARNING
-Serious personal injury may occur as a result
of improperly performed maintenance, ad ­
justments or repairs .
- Always be extremely careful when working
on the vehicle. Always follow commonly ac ­
cepted safety practices and general com­ mon sense. Never risk personal injury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fully familiar with these
or other procedures with respect to the ve­ hicle, or are uncertain how to proceed.
- Do not do any work without the proper tools
and equipment. Have the necessary work
done by your authorized Audi dealer or an­
other properly equipped and qualified work­
shop.
- The engine compartment of any motor vehi­ cle is a potentially hazardous area. Never
reach into the area around or touch the radi­
ator fan.
It is temperature controlled and
can switch on suddenly - even when the en­
gine is off . The radiator fan switches on au ­
tomatically when the coolant reaches a cer­
tain temperature and will continue to run
until the coolant temperature drops.
- Always switch off the ignition before anyone
gets under the vehicle .
-Always support your vehicle with safety
stands if it is necessary to work underneath
the vehicle . The jack supplied with the vehi­
cle is not adequate for this purpose and
could collapse causing serious personal in­
jury.
- If you must work underneath the vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels are always securely blocked and that
the engine cannot be started.
- Always make sure the transmission selector
lever (automatic transmission) is in P (Park
position) and the park brake is applied .
