2011 AUDI A5 COUPE four wheel drive

_____ o_ n_ t_h _e_ r_o _a _ d ________________________________________________ _
When stopping at a traffic signal or stopping in city traffic on vehicles
with an automatic transmission, the parking brake can be applied.
The vehicle does not have to be held with the footbrake . The parking
brake eliminates the tendency to creep with a drive range engaged.
As soon as you drive
off as usual, the parking brake is released auto ­
matically and the vehicle starts to move.
Starting on slopes
When starting on inclines, the starting assist prevents the vehicle
from unintentionally rolling back. The braking force of the parking
brake is not released until sufficient driving force has been built up at
the wheels .
[I) Tips
For safety reasons, the parking brake is released automatically only
when the driver 's safety belt is engaged in the buckle. •
Starting off with a trailer
To prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and prevents the vehicle from
rolling backward.
- You can release the switch once you are sure that you are
developing enough driving force at the wheels by
depressing the accelerator.
Depending on the weight of the rig (vehicle and trailer) and the
severity of the incline, you may roll backwards as you start. You can
prevent rolling backwards by holding the parking brake switch pulled
out and accelerating -just as you would when starting on a hill with a
conventional hand brake. •
Emergency braking
In the event that the conventional brake system fails or
locks.
- In an emergency, pull the switch and continue to pull it to
slow your vehicle down with the parking brake .
- As soon as you release the switch or accelerate, the
braking process stops.
If you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initiated. The vehicle is
braked at all four wheels by activating the hydraulic brake system.
The brake performance is similar to making an emergency stop:::>& .
In order not to activate the emergency braking by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled. As soon as
the switch is released, or the accelerator pedal is depressed, emer­
gency braking stops.
& WARNING
Emergency braking should only be used in an emergency, when
the normal foot brake has failed or the brake pedal is obstructed.
Using the parking brake to perform emergency braking will slow
your vehicle down as if you had made a full brake application. The laws of physics cannot be suspended even with ESP and its associ­
ated components (ABS, ASR, EDS). In corners and when road or
weather conditions are bad, a full brake application can cause the
vehicle to skid or the rear end to break away· risking an accident. •
Driver messages in the instrument cluster
Warning Vehicle incline is excessive
This message appears when the parking brake is applied on an incline
that exceeds about 30%. ._

pressing the=> page 236, fig. 198 button. When it is activated, the
message
ESP/ASR on appears briefly in the display.
Deactivating
You can deactivate the ASR if req uired by press ing the button (for less
than 3 seconds) =>
page 236, fig. 198. With the ASR deactivated, the
ESP check light comes on, see=>
page 15. The message ASR off
appears in the display as well. The ASR can be deactivated at any
speed.
The ASR should normally be activated all the time . Only in certain
exceptional situations when some slip is desirable does it make sense
to deactivate the ASR. Examp les:
• when driving with tire chains
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck .
When the abnormal situation is over, you sho uld activate the ASR
again.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
(I) Tips
To ensure that the ASR works properly, all four whee ls must be fitted
with ident ical tir es . Any differences in rolling radius of the tir es can
cause the system to reduce eng ine power when this is not desired .

General information
What
affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending la rgely on ope rating conditions and driving habits=>& .
On vehicles that are either driven mostly in stop-and-go city traffic or
are driven hard, the brake pads should be checked by your authorized
Audi dealer more often than specified in the
Warranty & Mainte ­
nance booklet.
Failure to have your b rake pads inspected can result
in reduced brake performance .
On steep slopes, you should use the braking effect of the engine. This
way, you prevent unnecessary wear on the brake system. If you must
use your brakes, do not hold the brakes down continuously. Pump the
brakes at intervals.
Noises may occur when b rak ing depending on the speed, braking
force and outside cond itions such as temperatu re and humid ity.
Moisture or road salt
If you are driving faster than 31 mph (50 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regula r interva ls so as to improve reaction time when braking on wet
surfaces. You, the driver, will not not ice anything.
Under certain condit ions, for example, when driving through water or
very heavy rai n, or even after washing your vehicle, the braking effect
can be reduced due to moisture (o r in free zing conditions ice) on the
bra ke pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings.
Th e effectiveness of the brakes can be reduced when the vehicle is
dr iven on a salt-covered road and the brakes are not used. H ere too,
you should clean off accumu lated salt coating from brake discs and
pads with a few careful applications of the brake=>&,.

Servotronic® - advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort .
The advanced Servotronic® power steering system senses the road
speed and ele ct ronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
veh icle speed .
Power steering will not work if the engine is off . As a resu lt, the
steeri ng wheel will be hard to turn.
T he power steeri ng fluid level is checked du ring the sched uled main ­
tenance services .
0 Note
If there is an electronic malfunction, servotronic will still function
like a conventional power s teer ing system, provid ing a cons tant
steering support force that is no longer proportionate to the vehicle
speed. This is most noticeable when t urning the s teer ing wheel at low
speeds (for example when park ing) , - more effor t will be required
than us ua l.
• Be aware of the d ifferent than usual steering response and adjust
your stee ring force accord ingly .
• Have the prob lem checked and set r ight by an Audi dealer as soon
as possib le.
[ i ] Tips
• When the e ngine is running, neve r hold the stee ring whee l turned
all the way to the rig ht or to the left for longer than 15 seconds. The
powe r steering pump wi ll overheat the hydra ulic fluid if yo u keep
holding the steering wheel turned all the way . This is likely to damage
t he power s teer ing system . •
If the power steering system s hou ld fa il entirely, or if the engine
is no t ru nning (fo r examp le, while be ing towed), you will st ill be able
to steer the vehicle. However,
considerably more effort will be
req uired to do so .
• If the power steering system should have a leak, or is not func­
tioning prope rly, con tact your au thor ized A udi dealer immedia tely.
• The power steer ing system requires a specia lly formulated
hyd raulic fluid. The power steer ing rese rvoir is the one loc ated
farthest to the rear on the left s ide of the eng ine compartme nt
=>
page 2 76 . T he correct fluid leve l in the reservo ir is im port an t fo r
proper functioning of the power steeri ng .•
Dr"ving with your quattro®
With all wheel drive, all four wheels ore driven.
General information
With all wheel d rive, power is d istributed to all four wheels. This
h appens a utomatically depending on your dr iv ing style and t he road
conditions at the time . See also =>
page 238, "Electronic different ial
loc k (ED L)".
T he all whee l dr ive concept is designed for high engine power . Your
veh icle is except ionally powe rf ul and has excellent driving character­
istics both under normal driving condit ions and on snow and ice .
Always read an d fo llow safety precautions =>& .
Winter tires
When driving in the winter, your vehicle with a ll whee l drive has an
adva ntage, even w ith regular t ires . In winter road cond it io ns it may
be advisable to mount winte r tires (or all-seaso n tires) for improved
dr iveability a nd b rak ing: t hese tires mus t be mounted on
all four
wheels . See also => page 307, "Winter ti res" .
Tire chains
Where tire chains are mandatory on certa in roa ds, this norma lly a lso
applies to veh icles with a ll w heel drive =>
page 308, "Snow chains" . Iii-

Tire pressure
Incorrect tire pressure causes premature wea r a nd can cause sudden
t ire blow-out. For this reason, ti re p ressure must be checked at least
once a month ~
page 297.
Driving style
Driving fast around curves, heavy acce le ra tion and hard brak ing
increase tire wear .
Rotating tires for more even wear
For all four tires on your veh icle to have the same service life, we
re commend that the fron t and re a r tires are rotate d according to the
tire manufact urer's suggested tire rotation interva ls . Please
remember the fo llow ing:
• Tir e rotat ion inte rvals may differ from t he ve hicl e service intervals
outlined in your Maintenance and War ranty Booklet .
• T he longer one tire is used in one location on the veh icle, the more
it wears at certa in points; therefore, we recommend that you follow
t he t ire m anufac ture r's suggested tire rotation in terva ls.
• V ehicles with front-whee l drive expe rience mo re tread wea r on t he
fron t wheels compa red to all-whee l drive (quattro
® ).
• Please rotate tires as s hown ~fig. 215.
• Extra care must be taken when rotating d irection-specific tires
~ page 321.
Wheel balancing
The w heels on new vehicles are balanced. Howeve r, va rious sit uat io ns
dur ing eve ryday dr iv ing can cause them to become unbalanced,
re su lt ing in v ibr ations yo u can usually fee l throug h the steering
wheel.
Unbalanced wheels must be rebalanced to avoid excessive wea r on
steeri ng, suspension and t ires . A wheel must also be rebalanced
w hen a new tire is installed.
Incorrect wheel alignment
Incorrec t whee l alignment can ca use excessive tire wear, impai ring
t he sa fety of the veh icle . If tires show excess ive wear, have the wheel
alignment checked by an authorized A udi dealer or qualified wo rk­
shop .
All wheel drive
Vehicles w ith q uattro ® must always have ti res of the same size,
const ructio n and trea d type. For details see~
page 242 .
& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wea r ind icato rs.
• Worn tire s are a safety hazard, they do not grip well on wet
roads and in crease your risk of "hydroplaning" and lo ss of control.
• Always keep chemicals that can cause tire damage, such as
grease , oil , gasoline and brake fluid away from tires.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •

& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combination s can lead to loss of control, collision
and serious personal injury.
• Always u se tire s, rim s and wheel bolts that meet the specifica­
tions of original factory -installed tires or other combinations that
have been specifically approved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly,
e specially at high speed s. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at

tire failure and loss of vehicle control.
• All four wheels must be fitted with radial t ires of the same
type , size (rolling circumference ) and the same tread pattern .
Driving with different tires reduces vehicle handling and can lead
to a loss of control.
• If the spare ti re is not the same as the t ires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with extra care. Refit the
normal road wheel as soon as safely possible .
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated becau se tire s that are driven faster than
their rated speed can fail suddenly .
• Overloading tire s cau se heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated
and not over or unde rinflated.
• For technical reasons it is not always possible to u se wheels
from other vehicles- in some cases not even wheels from the same
vehicle model. ..,_
