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
F ig . 198 Engine compa rtment: mark in gs on t he coo lant
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.
(J) Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the eng ine.
If this is the case, do not ..,_

.&_ WARNING
Improper use of the vehicle jack can cause se­
rious personal injuries.
- Never use the screw driver hex head to
tighten wheel bolts, since the bolts cannot
atta in the necessary tightening torque if you
use the hex head, potentially caus ing an ac­
c ident.
- The factory-supplied jack is intended only
for your vehicle model. Under no circum­
stances should it be used to
lift heavy
vehicles o r other loads; you r is k inju ring
yo urself.
- Never start the engine when the vehicle is
ra ised, whi ch could cause an accide nt.
- Support the veh icle secure ly with app ropr i­
ate stands if wor k is to be perfo rmed under­
neath t he vehicle; otherwise, the re is a po­
tent ial risk for in jury.
- Never use the jack s upplied with your Audi
on another vehicle, par tic ularly on a heav ier
one. The jack is only suitab le for use on the
vehicle it came with .

fo re remo unting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When us ing a spare tire with a tread pattern in­
tended for use in a spec ific d irection, p lease note
the following:
- The direct ion o f rotat ion is marked by an a rrow
o n the side of the tire.
- If the spare tire has to be installed in the incor­
rect d irection, use the spare tire only tempora­
rily s ince the tire w ill not be ab le to achieve its
o ptimum performance charac ter istics wi th re­
gar d to a quaplaning, noise and wea r.
- We recommend t hat you pay particular atten­
tion to this fac t during wet weathe r and t hat
yo u ad just yo ur speed to match road condi­
tio ns.
- Replace the f lat t ire with a new one and have i t
i ns ta lled on yo ur ve hicl e as soon as possibl e to

tio nal ti re.
Notes on wheel changing
Plea se read the info rmation ¢ page 2 60 if you
are go ing to use a spare tire which is different
from the tires on your vehicle.
Af te r yo u change a tir e:
- Check the tire pressure on the spare immedi­
ately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos -
288
sible by your authorized Audi dealer or a
qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lb (120 Nm ).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire,
they should be replaced before you check the
t ightening torque.
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi ­
ble. Remount the wheel cover .
Until then , drive with extra care and at reduced
speeds.
& WARNING
- If you are going to equip yo ur vehicle with
tires or r ims which diffe r from those which

Emergency assistance
-Avoid full-throttle acceleration, heavy brak­
ing, and fast cornering. You risk having an
accident.
- Never dr ive using more than one spare
wheel and tire. You risk having an accident.
- Normal summer or winter tires must not be
mounted on the compact spare wheel rim.
- For technical reasons, the use of tire chains
on the spare tire is not permitted. If it is
necessary to drive with tire chains, the spare
wheel must be mounted on the front axle in
the event of a flat in a rear tire. The newly
available front wheel must then be installed
in place of the rear wheel with the flat tire.
Installing the tire chain before mounting
the wheel and tire is recommended.
- Loose items in the passenger compartment
can cause serious personal injury during
hard braking or in an acciden t. Never store
the inflatable spa re tire or jack and tools in
the passenger compartment.
- Normal summer or winter tires must not be
mounted on the compact spare wheel rim .

12. Close the battery cover .
The battery is vented to the o utside so that not
gases enter the passenger compartment. Make
sure that the connected positive terminal clamps
on the jump start cab le have sufficient contact
with m etal.
.&_ WARNING
Follow the warnings and instructions from
the jump start cable manufacturer to reduce
the risk of serious injuries and vehicle dam­
age. If you are unsure about anything, call
roads ide assistance.
- The jump start cables must be long enough
so that the veh icles do not touch .
-
-Route the jump start cables so they cannot
get caught in the moving parts in the engine
compartment .
- Always read and follow the warnings before
check ing anything in the engine compart­
me nt ¢
page 236.
Connecting jump start cables incorrectly can
destroy the alternator .
- Always connect the positive terminal(+) to
the positive term inal( +) and the negative
term inal(-) to the negat ive termi nal( -) on
the body ground po int, but not the negative
te rminal on t he battery.
- Make sure the screw plugs on the battery
ce lls are installed securely .
If not, tighten
the p lugs before connecting the clamps to
the negat ive termina l on the battery.
- Please note that the connecting p rocess de­
scribed below for the j ump start cables is in-
Emergency s ituatio ns
tended for when your vehicle is be ing j ump
started.
If you are jump starting another ve­
hicle, do not connect the negat ive cab le to
the negative term inal( -) on the dra ined
battery, but rather connect it to a large
metal component that is bolted secure ly to
the engine block, or to the engi ne b lock it­
self . If the batte ry in the veh icle being jump
s tarted is not ven ted to the outside, there is
a risk of explos ion due to hyd rogen gas .
- Make sure that the connected pos itive ter­
m inal clamps have suff ic ien t conta ct with
metal.
- Do not use the battery negative terminal for
jump starting or a m alfunction co ul d o ccur
in the vehicle e lectrica l system.
