light AUDI Q5 2013 Workshop Manual

Your vehicle is equipped with an electrome­
chanica l parking brake . The parking brake is
des igned to prevent the vehicle from ro lling
un intent ionally and replaces the hand brake.
I n addition to the norma l functions of a tradi­
tional hand brake, the electromechanica l
parking brake provides various convenience
and safety functions.
When start ing f rom re st
- T he integral starting assist helps you when
driving by automatically releasing the park­
ing brake ¢
page 90, Starting from rest.
-When starting on inclines, the starting as­
sist prevents the vehicle from unintentional­
l y rolling back. The braking force of the
parking brake is not released until sufficient
driv ing force has been built up at the
wheels .
Emergenc y bra ke function

Starting/stopping the engine
Applies to vehicles: with Start-Stop-Syste m
Fig. 102 Instrument cluste r: Eng ine switched off (stop
phase)
.. Slow the vehicle to a stop using the brake
and keep pressing the brake pedal. The en­
gine w ill switch off. The
[IJ indic ator light
appears in the instrument cluster display
and - also appears in the trip com­
puter .
.. When you take your foot off the brake ped­
al, the engine restarts. The indicator light
turns off .
Additional information
The engine will switch off in the P, 0/5 and N
positions as well as in manual mode. In the P
position, the engine will also remain off if you
take your foot off the brake pedal. The engine
starts again when you select another selector
lever position and take your foot off the brake
pedal.
If you select the R position during a Stop phase, the eng ine will start aga in .
Shift from 0/5 to P qu ickly to prevent the en­
g ine from starting unintentionally when shift­
ing through R.
You can determine for yourself if the engine
will stop or not by reduc ing or increasing the
amount of force you use to press the brake
pedal. For example, if you only lightly press
on the brake pedal in stop-and and-go traffic
or when tu rning, the eng ine will not switch off
when the vehicle is stationary. As soon as you
press the brake down harder, the engine will
switch off.
(D Tips
-Press the brake pedal during a stop
phase to keep the vehicle from rolling.
- When you stop and the start-stop-sys­
tem turns the engine off, the ignition re­
mains on. Make sure that the ignition is
switched off before exiting the vehicle.
- The ignition will turn off if you press the
!START ENGINE STOPI * button during a
stop phase.
- The image in the display is slightly differ ­
ent in some models.

Before each stop phase, the system checks if
certain conditions have been met. For exam­
ple , the eng ine will
not be switched off in the
following sit uations:
- The engine has not reached the minimum
required temperature for Start-Stop -mode.
- The interior temperature selected by the A/C
system has not been reached.
- The outside temperature is extremely high/
low.
- The windsh ield is being defrosted

your speed and the distance between
your vehicle and other vehicles.
- For reasons of safety, cruise control
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
plan ing) -you could have an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal causes
cru ise contro l not to brake. This is due to
the control system being overridden by
the driver's acceleration.
- Never use the cruise control when driving
off-road or on unpaved roads. The cruise
con tro l is intended for use only when the
vehicle is being operated on paved roads,
and is not suitable for use off-road or on
unpaved roads.
- If a brake system malfunction such as
overheating occurs when the cruise con ­
trol system is switched on, the braking
function in the system may be switched off. The other cruise control functions re­
main active as long as the indicator light

Fig. 109 Center console: c:f,V button
.,. To turn on EV mode, press the ld"I button .
The indicator light in the button will turn
on . The. indicator light a lso turns on in
the instrument cluster display.
The functions and operating modes described
be low are se lected automatica lly by the vehi­
cle control system, depending on the vehicle
operat ing status. This ensures that the vehicle
is always in the correct operating mode. One
exception is the enhanced electric driving
mode (EV mode), which is activated by the
driver
¢pag e 100.
Driving with the combustion engine
The vehicle is powered by the combustion en­
gine. The h igh voltage battery is charged si­
multaneously, if needed.
Full acceleration (boost)
In full acceleration, the vehicle is powered by
both the combustion engine and the electric
motor . This operating mode is called
Boost
and is on ly available for a short amount of
time because it uses so much energy. Availa ­
bility depends on the high voltage battery
charge level.
The boost operating mode is activated by
pressing the accelerator pedal all the way
down.
Electric driving
The vehicle can be driven completely electri­
ca lly depending on the high vo ltage battery
charge level and the driving resistance. The
combust ion eng ine turns off at that t ime.
The combustion engine starts when accelerat ­
ing or when the high voltage battery charge
level drops be low a certain threshold. The ve­
hicle resumes e lectric driving once the accel­
eration and the high voltage battery charge
level permit.
Enhanced electric driving mode (EV
mode)
Pressing the 1~ 1 button ¢ fig. 109 can extend
the usual limits on electric driving so that you
can always drive in electric mode, if the condi­
t ion of the e lectr ica l system permits . The op­
erating mode is then set to maximum electric
drive @,@ ¢
page 98, fig. 108. It can be
driven complete ly elec trically for up to 1.8
miles (3 km) at a constant 37 mph (60 km/h) .
T he following conditions must be met to act i­
vate the enhanced e lectr ic drive:
- The high voltage battery must be suffic ient­
ly charged.
- The temperature of the 12 volt batter ies
and the hig h voltage battery must be suffi­
cient.
- The vehicle speed must not be higher than
62 mph (100 km/h).
- The transmission must not be in tiptronic
mode.

-ESC offroad mode and hill descent assist
must not be turned on¢
page 198 .
The combust ion eng ine tu rns on and inter­
rupts
the enhanced electric d rive mode when
the vehicle is accelerated. The gray indicator
light
l!I also turns on in the disp lay. The en­
hanced electric drive mode resumes automati ­
cally once acceleration stops.
The enhanced e lectric drive mode is
deactivat­
ed if at least one of the following conditions is
met :
- The ign ition is turned
off.
- Th e 1.:1"1 button is pressed again.
- The high voltage battery charge level is low .
- The vehicle speed is higher than approxi -
mately 62 mph (100 km/h).
- The S selector lever position or tiptronic
mode is selected .
- ESC offroad mode or hill descent assist is
switched on .
T he
ld" I button must be pressed to reactivate
it .
Start-Stop function
The combustion engine is operated on ly as
needed. Generally, the combustion engine
turns
off when the vehicle is stationary and
the high voltage battery powers the electrical
vehicle systems.
The purpose of automatica lly shutting the
combustion engine
off in hybrid drive mode is
to save fuel. All of the important veh icle sys­
tems, such as steering, brakes and the A/C
system, cont inue to remain active. In some
cases , systems may require the combustion
engine to cont inue running when the vehicle
is stationary. When dr iv ing in congested traf­
fic for long per iods of time, the comb ustion
engine w ill cycle on when the vehicle is sta­
tionary to keep the high voltage battery
charged.
Gliding
I f the gas pedal is not pressed and the D posi­
tion is selec ted, the combustion engine re-
Hybrid 101
mains turned off up to speeds of approxi ­
mately 99 mph (160 km/h). Driving conserva­
tive ly like this can reduce fuel consumption.
Energy recovery (recuperation)
When braking, the electric motor will act as a
generator creating e lectric energy that is then
stored in the high voltage battery. This also
occurs when the ve hicle is coasting or driving
downhi ll. The combustion engine is automati­
cally turned
off i n this case.
The vehicle is braked with the electric motor
by applying ear ly and even pressure to the
brakes and using short pedal movements
¢
page 98, fig. 108 @. By doing this, a large
amount of the kinetic energy is recovered and
may be stored as electric energy in the high
voltage battery . During heavy braking, the
convent ional brakes are also act ivated
¢ page 98, fig. 108 @.
The energy recovery is shown in the MMI dis­
play ¢
page 104.
Automatic start of the combustion engine
Various operating conditions cause the com­
bust ion engine to start automat ically :
- The high voltage battery charge leve l is low.
- The temperature of the combustion engine
is low.
- The temperature of the catalytic converter is
low .
- The power output needed for the A/C sys-
t em is high.
- The vehicle speed is high.
- The vehicle acceleration is high.
- The inclin e is steep.
- High charge level for the high voltage bat-
tery when coasting. In th is case, the h igh
voltage battery cannot absorb any more en ­
ergy and so the electric motor cannot slow
down the veh icle. The combustion engine
tu rns on (engine brake). In this situation the
h igh voltage battery will show a Max charge.

Additional information about the vehicle tool kit may be found under
c::> page 269 and
about the tire repa ir set under
c::> page 2 72 .
(D Tips
The right storage compartment in the lug­
gage compartment and its contents must
always be kept in the vehicle. The veh icle
m ust not be operated w ithout the tire re­
pa ir set.
Charging the batteries
Applies to vehicles: with hybrid drive
The vehicle is equipped with two 12 volt bat ­
ter ies and a h igh voltage battery.
If the
12 volt batter ies are dead, they may be
charged with a charger or the vehicle may be
jump started with assistance from another ve­
hicle in the same way as a conventional vehi­
cle .
The same applies to the high voltage battery
if it is d ischarged . However, in this case, the
charg ing process is accompanied w ith mes­
sages in the inst rument cluste r display. The
i gnit ion m ust be switched on and all unneces­
sary electric components m ust be turned off.
The connections in the engine compartment
are used for both charging and jump starting
c::> page 245 or c::> page 284.
Vehicle not ready to start. See owner's
manual
This message appears if the high voltage bat­
tery charge level is too low. The vehicle can no
l onge r be started with its own power. The
high voltage battery must be charged with a
charger or the vehicle must be jump started
with the aid of another vehicle.
Afte r the connecting the cha rger or jumper ca­
b les, the ignition must be turned off for ap­
proximately two minutes and then turned on
again. After no more than one m inute, one of
the following indicator lights turns on in the instrument cluster d isp lay. Hybrid 105

with assistance from another vehicle.
If the 12 vo lt batteries are dead, the -
indicator light turns on. The charging proce­
dure takes longer in this case because the
12

goes faster with the ignition switched off.
Vehicle ready to start.
This message appears if the charging proce­
dure was successfu l. The vehicle may be start­
ed again.
Battery could not be charged enough to
start vehicle.
T his message appears if the charging proce­
dure was not successful or it was interrupted.
This may happen if the charger or the battery
in the veh icle that is assist ing is too weak.
If
the vehicle cannot be started, see an author­
ized repa ir facility for assistance .
(D Tips
- The charger should deliver a current of at
least
30 A. Otherwise charging the high
voltage battery will take considerably longer. A current between
50 A and 70 A
is ideal.
- The ve hicle that is assist ing should be
somewhat within the same vehicle class
when jump starting a vehicle. A smaller
vehicle's battery may be drained.
- After approximately
30 minutes, the
c harging procedure ends because the ig­
nition is automatically turned off.
If you
would like to continue to charge the bat­
tery, turn the ignition on again.

Audi adaptive cruise control and braking guard 113
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 124 Instrument cluste r: approac h warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive cruise control is switched off.
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own vehicle is traveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Braking
gua rd does not react if it cannot detect the
situation .
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you wi ll
not be able to avoid a collision. The indicator
light
I in the display comes on .
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. The indicator
light
I and indicator in the display will warn
you about the danger
c:> fig. 124. You will al­
so hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, braking guard will inter-
ll Th is is not ava ilable in som e coun tri es.
vene by braking and the message Braking
guard: Activated
will appear.
- If a coll ision is imminent , the sys tem wi ll
first provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake within the limits of
the system. This reduces the vehicle speed
in the event of a collision.
- At speeds under 20 mph (30 km/h), the sys­
tem can initiate a complete deceleration shortly before a collision
ll.
- If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the braking force .
Which functions can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio/
MMI* i::!> page 114, Settings in the radio/
MMI *.
A WARNING
--==
Lack of attention can cause collisions, oth-
er accidents and serious personal injuries.
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The driver is
always respons ible for braking at the cor­
r ect time .
- Always pay close attention to traffic,
even when the braking guard is switched
on . Be ready to intervene and be ready to
take comp lete control whenever necessa­
ry. Always keep the safe and legal dis­
tance between your vehicle and vehicles
up ahead.
- Braking guard works within limits and
will not respond outside the system lim­
its, for examp le when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traff ic).
