2015 AUDI A5 wheel

Smart Technolog y
Clean off accumulated salt coating from
brake discs and pads w ith a few carefu l
brake applications .
- If you damage the front spoiler, or if you in­
stall a d ifferent spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc ­
ing the effectiveness of the entire brake sys­
tem.
- Failure of one brake c ircuit will impair the
braking capab ility result ing in an increased
stopp ing distance. Avoid driving the veh icle
and have it towed to the nearest autho rized
Audi dealer or qualified workshop.
- Never let the vehicle ro ll to a stop with the
engine shut off .
- If the brake booster is not work ing, the
brake pedal must be pressed considerably
harder to make up for the lack of booste r as­
sistance .

Driving with your quattro
Applies to vehicles : wit h all -w hee l drive
With all-wheel drive , all four wheels are driven .
General information
With a ll-wheel drive, power is distrib uted to a ll
fo ur wheels . This happens automatica lly depend­
i ng on your driving style and the road conditions
at the t ime . See also <=> page 1 70 .
A center d ifferential distributes the driving power
variab ly to the front and rear ax le. It works to­
gether w ith select ive whee l torque control , which
activates when drivi ng throug h curves

The all-wheel drive concept is designed for high
engine power . Your vehicle is exceptionally pow­
erful and has excellent driving character istics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­
cautions <=>
,&.
Winter tire s
When driving in the winter, your vehicle with all­
wheel drive has an advantage, even with regular
tires. In winter road conditions it may be advisa­
ble to mount w inter tires (or all-season tires) for
improved driveability and braking: these tires
must be mounted on
all four wheels. See also
<=> page 220, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also applies to vehicles with
all-wheel drive <=>
page 220, Snow chains.
Replacing wheels/tires
Vehicles with all-wheel drive must a lways have
tires of the same size. Also avoid tires with differ­
ent tread depths. For details see page
<=>
page 212, New tires or wheels.
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road vehicle. It is there­
fore best to avoid rough tracks and uneven ter­
rain as much as possible. Also refer to
<=>page 177.
A WARNING
Always adjust your driving to road and traffic
conditions. Do not let the extra safety afford­
ed by all-wheel drive tempt you into taking
extra risks.
- Although the all-wheel dr ive is very effec­
t ive, always remember that braking capacity
is limited by tire traction. You should there­
fore not drive at excessive speeds on icy or
slippery road surfaces.
- On wet road surfaces, be careful not to dr ive
too fast because the front wheels could be ­
gin to slide on top of the water (aquap lan­
ing). If this shou ld occur, you will have no

warning from a sudden increase in engine
speed as with a front-wheel drive vehicle.
Always drive at speeds which are suited to the road conditions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa­
bility of electrical energy for starting the engine.
If a vehicle with a conventional energy system is
not driven for a long pe riod of time, the battery
is discharged by idling current consumers (e.g.
i mmobil izer). In certain circumstances it can re­
su lt in there being insufficient energy available to
start the engine.
Intelligent energy management in your vehicle
hand les the distribution of electrical energy.
Starting ability is markedly improved and the life
of the battery is extended.
Basically, energy management consists of
bat­
tery diagnosis , idling current management
and
dynamic energy management.
Battery diagnosis
Battery diagnosis continuously determines the
state of the battery . Sensors determine battery
vo lta ge, battery current and battery tempera­
tu re. This determines the current state of charge
and the power of the battery.
Idling current management
Idling current management reduces energy con­
sumption whi le the vehicle is standing. With the
ignition switched off, it contro ls the energy sup­
ply to the various electrical components. Data
from battery diagnosis is considered.
Depending on the battery's state of charge, indi­
vidual consumers are gradually turned off to pre­
vent excessive discharge of the battery and thus
maintain starting capability .
Dynamic energy management
While the vehicle is being driven, dynamic energy
management distr ibutes the energy generated ..,.

Trailer mode notes
Important to know
Your vehicle hand les differently when tow ing a
trailer because of the additional weight and dif­
ferent weight distribution. Safety, performance
and economy will greatly depend on how careful­
ly you load your trailer and operate your rig.
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic. Keep practicing until you have be­
come completely familiar with the way your vehi­
cle-trailer combination behaves and responds.
Backing up is difficult and requires practice. Back­
ing up with a trailer generally requires steering
action opposite to that when backing up your ve­ hicle without a trailer .
Maintain a greater distance between your vehicle
and the one in front of you. You wi ll need more
room to stop. To compensate for the trailer, you
will need a larger than normal turning radius.
When passing, remember that you cannot acce l­
erate as fast as you normally would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your vehicle.
- If you tow a trailer, your A udi may require
more frequent maintenance due to the ex­
tra load
¢ page 244 .
Parking on a slope
Do not park on a slope with a trailer. If it cannot
be avoided, do so only after doing the following:
When parking:
~ .. Apply the foot brake.
~ .. Have someone place chocks under both the ve-
~ hide and the trailer wheels . ..,.,
N ..,., ,....,
Trailer mode
.. With chocks in place, slowly release the brakes
until the wheel chocks absorb the load.
.. Turn the whee ls towards the curb .
.. App ly the parking brake.
.. Place an automatic transmission* in P, respec­
tively a manual transmission in first or reverse
gear .
When restarting after parking:
.. App ly the foot brake.
.. Start the engine.
.. Move the selector lever to D/S, respectively a
manual transmission in first gear .
.. Release the parking brake and slowly pull out
and away from the wheel chocks.
.. Stop and have someone retr ieve the wheel
chocks .
(D Tips
If you move the selector lever of the automat­
ic transmission* to P before applying the
parking brak e and before blocking the wheels,
you may have to use more force later to move
the lever out of the P position.

-To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the w inter . The brakes
must be dried first w ith a few careful brake
applications.
(I) Note
- If you wash the vehicle in an automatic car
wash, you must fold the exterior m irrors in
to reduce the risk of damage to the mirrors. Power folding exterior mirrors* must only
be fo lded in and out us ing the power folding
f u nct ion.
- To prevent pa int damage, do not wash the
vehicle i n direct sunlight .
- To reduce the risk of damage to the surface,
do not use insect removing sponges, k itche n
sponges or similar items.
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax.
It can destroy
the matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish pa int. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
On ly wash the vehicle in facilit ies specially de­
signed for that purpose. This will reduce the
risk of dirty water contam inated with o il from
entering the sewer system .

Wheels and Tires
General information
.,.Che ck your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protec t your tires from oil,
grease and fuel.
.,.Ma rk tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
.,.Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold tem­
peratures, cracks can form on
the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.
