2012 AUDI A5 COUPE parking brake

Using the parking brake to perform emer­
gency braking will slow your vehicle down
as if you had made a full brake application.
The laws of physics cannot be suspended
even w ith ESP and its associated compo­
nents (ABS, ASR, EDS). In corne rs and
when road or weather conditions a re bad,
a full brak e application can cause the vehi­
cle to skid or the rear end to break away -
r isking an accident.
Driver messages in the instrument
cluster
Caution: Vehicle parked too steep
This message appears when the park ing brake
is applied on an incline that exceeds about
30%.
In this case the braking power of the parking
brake may
not be adequate to prevent the ve­
hicle from rolling unintentionally .
Press brake pedal to release parking brake
This driver message appears when the switch
to release the parking brake was pressed. The
parking brake can only be released if you step
on the brake pedal and at the same time press
the switch or you automatically release the
parking brake with the start ing ass ist

shown in the display<=> fig. 109. The display
may vary, depending on the type of display in
your vehicle. The ind icator light
mJJlm (US model)/ . (Canad ian model) will
also light up in the instrument cluster .
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
A WARNING
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for ..,.

react when you drive towards an obstacle
or something else on or near the road
t h at is not moving, such as vehicles stop­
ped in a traffic jam, a stalled or disabled
vehicle .
- Always remember that the adaptive
cruise control cannot detect a vehicle
that is driving towards you in your traffic lane and that it cannot detect narrow ve­
hicles such as motorcycles and bicycles.
(D Tips
- Fo r safety reasons, the stored speed is
deleted when the ignition is turned off .
- The Electronic Stabilization Program
(ESP) and the Anti-Slip Regulation (ASR)
cannot be deactivated when the adaptive
cruise control is switched on. If the ESP
and the Anti-Slip Regulation (ASR) has been deactivated and you then switch on
the adaptive cruise control, the ESP func­
tion will also be activated automatically.
- Damage caused by accidents (e.g. if the
vehicle is damaged when parking) can af­
fect the radar sensor settings. This can
cause the system to malfunction or
switch off complete ly.
- The radar sensor cover is heated. In win­
ter cond itions, you should still check be­
fore driving to make sure it is free of ice
and snow. If necessary, clean the area
near the radar sensor carefully
9 fig. 110.
-To ensure that the radar sensor is not
blocked, foreign objects (e.g . stickers,
add-on parts) must not cover the area near the radar sensor
9 fig. 110. The
area near the radar sensor must not be painted, either.

Adaptive cruise control 103
How does adaptive cruise control work?
App lies to veh icles: w ith adaptive cru ise control
Vehicles traveling ahead are detected with
the aid of a radar sensor.
Fig. 111 Radar sensor measu re m ent range
A radar sensor is built into the front of the ve­
hicle
9 fig. 111, which is subject to certain
system limits~
page 112. Stationary objects
are not taken into consideration. The system
is intended to measure the distance to reflec­
tive surfaces. The system responds after the
distance measurement has taken place. If a
measurement is not possible, the system does
not respond .
Open road
When the road is clear, the adaptive cruise
control works like cruise control. It maintains
a constant target speed specified by the driv­
er.
Driving in traffic
If a vehicle driving ahead is detected, the
adaptive c ruise control decelerates (within the
Limits of the system)

tervention prompt
and 9 page 112, System
limitations
to its speed and after adjusting,
tries to maintain the set distance from the ve­
hicle ahead . Th e vehicle may temporarily drive
slower than the set speed while adjusting
~.&. in Description on page 102.
If the vehicle in front accelerates, adaptive
cruise control also accelerates up to the speed
that you have set.
Situation requiring driver intervention
In some situat ions you will have to use the
footbrake to slow the vehicle down in order to .,..

any objects over an extended time period. For
the time being, the distance to vehicles up
ahead is not being controlled. The ACC system
is not switched off, so increased alertness is
required. The following may be reasons for
the text message ACC Functionally limited:
- The ACC sensor is dirty. The ACC system is
not reacting, or is not reacting correctly, to
vehicles traveling ahead .
- It is possible that you are driving on a road
with very light traffic
without anything at
the side of the road (e.g. guard rails, traffic
signs, trees). As soon as a vehicle is detected
by the system again, it returns to its control
range and the text message disappears.
The ACC sensor is located in the right front
trim grille
¢ page 102, fig . 110. If there is a
loss of operation due to heavy contamination,
this area should cleaned to restore proper op­
eration.
ACC not available
The text message ACC not available appears,
for example, if the temperature of the brakes
is excessive . Adaptive cruise control is tempo­
rarily not available. A warning tone sounds as
a reminder.
ACC not available!
The text message ACC not available! appears
in the event of a malfunction. Adaptive cruise
control is turned off. A warning tone sounds
as a reminder. Have the system inspected by a
qualified dealership.
ACC sensor blocked !
The text message ACC sensor blocked ! ap­
pears when the ACC system can no longer
guarantee safe detection of objects. Adaptive
cruise control is turned off. A warning tone
sounds as a reminder.
To decide whether it is necessary to switch off
the ACC (ACC sensor blocked
!) or if it is only a
temporary condition (ACC Functionally limit­
ed), the system will also takes into considera­
tion the outside temperature and/or the wind­
shield wiper operation. The
ACC sensor is dirty or blocked (e.g. leaves,
snow).
The sensor should be cleaned to restore prop­
er sensor function¢
page 102, fig. 110.
Engine speed !
The text message Engine speed ! appears in
vehicles with manual transmission when the driver did not shift up or down in time while
using adaptive cruise control braking or accel­
erating, causing the vehicle to exceed or not
reach the permitted limit speed. This causes
adaptive cruise control to deactivate automat­
ically. A chime sounds as a reminder.
Parking brake!
The text message Parking brake! appears if
emergency braking was manually initiated
with the Electromechanical Parking Brake
(EPB). The adaptive cruise control is turned
off. This is accompanied by a warning tone.
Stabilisation program
The text message Stabilisation program ap­
pears if the Electronic Stabilization Program
(ESP) has intervened. In this case the adaptive
cruise control is automatically turned off. This
is accompanied by a warning tone.
Speed
The set speed in mph (Canada km/h) always
appears when saving or changing the speed in
adaptive cruise control¢
page 104, How is
the speed stored?
and ¢ page 105, Changing
stored speed.
Speed too low
The text message Speed too low appears if
the current speed is too low
to set or to hold
the requested speed.
When setting a desired speed, it must be at
least 20 mph (30 km/h). At speeds below 12
mph (20 km/h), the cruise control is turned
off.
In speeds over 95 mph (150 km/h), the sys-
tem remains active and resumes the speed of .,..

This automatic adjustment process will cause
a
slight vib ra tion of the brake pedal and some
noises to alert you that vehicle speed must be
adapted to existing road and traffic condi­
tions.
A WARNING
Although the ABS is very effective, always
remember that braking capability is limit­
ed by t ire traction . A lways adjust your dr iv­
ing speed according to the road and t raff ic
conditions. Do not let the extra sa fety af­
forded by the ABS tempt you into taking
extra risks. The ABS cannot overcome the
laws of physics .
(D Tips
-If ABS is not functioning properly, a
warning light will come on . See
~ page 16.
-If a fault occu rs in the ABS, the EDL is al­
so not functioning . This is indicated by
the ABS warning light .
Brake assist
Brake assist is designed to achieve the opti­
mum broking effect.
Brake assist helps to increase the effective
brak ing power and thus to achieve a shorter
stopping distance. If the driver presses the
brake peda l very quick ly, brake assist auto­
mat ica lly boosts the braking force to the max­
imum level, up to the point where the anti­
lock brake function (ABS) intervenes to stop
the wheels from locking . You should then
keep the brake pedal pressed u ntil the vehicle
has braked to the required speed . Brake ass ist
sw itches itself off as soon as you release the
b rake peda l.
A WARNING
Please remembe r that the accident r is k al­
ways increases if yo u drive too fast, espe ­
cially in corners or on a s lippery road, or if
you fo llow the vehicle ahead of you too
close ly. Increased risk of an accident can-
Int ellig ent technolog y 209
not be compensated for even by brake as­
sist, so always maintain a safe speed.

advanced power
steering system
The power steering systems uses the power of
the running engine to allow precise steering
with little effort.
T he advanced Servotronic ® power steer ing
system senses the road speed and elect ron i­
ca lly adjusts power assistance to provide com­
fortab le and safe ste ering response exact ly
matched to the vehicle speed .
Power steering will not work i f the engine is
off. As a result, the stee ring wheel will be hard
to turn .
T he power steering fluid level is checked d ur­
ing the schedu led maintenance services .
(D Note
If there is an e lectronic malfunction, ser ­
votronic
will s till function like a conven­
tiona l power steering system, providing a
constant steering support force that is no
l onger proportionate to the vehicle speed.
This is most noticeable when turning the
steering wheel at low speeds (for example
when parking), -more effort w ill be re­
q uired than usual.
- Be aware of the different than usual
steering response and adjust your steer ­
ing force acco rdingly .
- Have the problem checked and set right
by an Audi dealer as soon as possible.
(D Tips
-Whe n the engine is running, never hold
the steering w heel turned all the way to
the rig ht or to the left for longer t han 15
seconds. The powe r steering pump will
overheat the hydraulic fluid if you keep
holding the stee ring wheel turned all the
way. This is likely to damage the power
steering system .

220 Trailer towing
who is not properly wearing the restraints
provided by Aud i.
Trailer towing tips
Important to know
Your vehicle hand les different ly when towing
a trailer because of the additional weight and
different weight distribution. Safety, perform­
ance and economy wi ll greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turning, stopp ing and backing up in an area
away from traffic. Keep practicing until you have become completely familiar with the way
your vehicle-trailer combination behaves and responds.
Backing up is difficult and requires practice.
Backing up with a trai ler genera lly requires
steering action opposite to that when backing up your vehicle without a trailer.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turn ing radius .
When passing, remember that you cannot ac­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your tra iler before chang­
ing lanes aga in.
Avoid jerky starts, sharp turns or rapid lane
changes .
(D Tips
-Do not tow a tra iler during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load
q page 293.
Parking on a slope
Do not park on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­ lowing:
When parking:
.. App ly the foot brake.
.. Have someone place chocks under both the
vehicle and the trailer wheels .
.,. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load.
.. Turn the wheels towards the curb.
.. App ly the parking brake.
.. Place an automatic transmission* in
P, re­
spectively a manual transmission in first or reverse gear.
When restarting after parking:
.. App ly the foot brake.
.. Start the engine.
.. Move the se lector lever to
D , respectively a
manual transmission in first gear .
.. Release the parking brake and slow ly pu ll
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 auto­
matic transmission* to
P before applying
the parking brake and before blocking the
whee ls, you may have to use more force
lat er to move the lever out of the
P posi­
tion.

238 Check ing and filling
- Apply the parking brake.
- Move selector lever of automatic trans- mission to "P" (Park); put manual trans­
mission in Neutral.
- Always let the engine coo l down . Hot
components will burn skin on contact.
- To reduce the risk o f being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment .
- Never spill flu ids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electr ic fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap when the eng ine is still warm. The cool­
ant system is pressur ized and hot coo l­
ant could spray out .
-Protect your face, hands and arm from
steam or hot eng ine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
-If work on the fuel system or the electri­
cal system is necessary :
- A lways disconnect the battery.
- Never smo ke or work near heaters or
open flames . Fluids in the engine com ­
partment co uld start a fire.
- Keep an approved fire ext inguisher im­
mediately available.
- T o avoid ele ctrical shock and persona l in ­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repa ir
with the engine running:
- Fi rst, fully apply the parking bra ke,
move se lec to r l ever o f automat ic trans- mission to
"P" (Park); put manua l
transmission in Neutra l.
- Always use extreme caution to p revent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wea r clothing that
will hang o r droop into the engine.
- M inim ize exposure to em iss ion and
chemical hazards
