Starting off with a trailer
To prevent rolling back unintentionally on an inÂ
cline, do the following:
11-Keep the switch pulled and depress the accelerÂ
ator. The park ing brake stays applied and preÂ
vents the vehicle from roll ing backward .
11-You can release the switch once you are sure
th at you a re developing enough dr iving force at
the whee ls by depressing the a cce le rato r.
Depending on the weight of the r ig (veh icle and
trai ler) and the severity of the inc line, you may
r oll bac kwards as you sta rt . Yo u can prevent rollÂ
in g ba ckwards by ho ld in g the pa rking brake
sw itch pulled o ut and accelera ting - just as you
wo uld when sta rting on a hill with a conventiona l
hand brake .
Emergency braking
In the event that the conventional brake system
fails or locks .
11-In a n eme rgency, pull the sw itch and conti nue
to pull it to slow your vehi cle down wi th the
parking brake .
11-As soon as you release the switch or acce le rate,
the braking process stops.
If yo u pull the sw itch and hold it above a speed of
about S mph (8 km/h), t he emergency braking
f u nction is init iated . The veh icle is braked at all
four whee ls by activating the hydra ulic brake sysÂ
t em. The brake performance is simi lar to making
an emergency stop¢.&. .
In o rder not to activate the emergency brak ing by
mistake, an audible warning tone (b uzzer)
sounds w hen the sw itch is p ulled. As soon as t he
sw itch is released, or the accelerator peda l is deÂ
p ressed, emergency brak ing stops.
A WARNING
Emergency b raking should on ly b e used i n an
eme rgency, when the normal foot brake has
f ail ed or the br ake pedal is obstruc ted. Using
t he par king brake to pe rform emergency brakÂ
ing w ill slow your vehicle down as if you had
made a fu ll brake a pplicat ion . The laws of
Dri ving
physics cannot be suspended even with ESC
and its associated components (ABS, ASR,
EDS). In corners and when road or weather
c o nditions are bad, a f ull brake application
can cause the vehicle to skid o r th e rear end to
b reak away -risking an accid ent .
Driver messages in the instrument cluster
Caution: Vehicle parked too steep
T h is message appears w hen t he pa rking brake is
applied on an in cli ne that exceeds about 30% .
In this case the braking power of the park ing
brake may
not be adequat e to prevent the veh iÂ
cle from rolling unintentionally .
Press brake pedal to release parking brake
This dr iver message appears when the sw itch to
release the parking bra ke was pressed. The par kÂ
ing brake can only be released if you step on the
brake pedal and at the same t ime press t he
switch or you automat ica lly release the parki ng

Before each stop phase, the system checks if cerÂ
tain conditions have been met. For example, the
engine will
not be switched off in the following
situations:
- The engine has not reached the minimum reÂ
quired 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 windshield is being defrosted ~
page 82.
-The park ing system* is switched on .
- The battery cha rge level is too low.
- The steer ing whee l is sharply turned or there is
a steering movement.
- After engaging the reverse gear.
Engine automatically restarts
The stop phase is interrupted in the following sitÂ
uations, for example. The engine restarts without
any action by the driver.
- The interior temperature varies from the temÂ
perature selected in the A/C system.
- The windshield is beeing defrosted
~ page 82.
-The brake pedal is pressed several times in a
row.
Driving
- The battery charge level becomes too low.
Switching the ignition off automatically
To prevent the battery from draining, the ignition
will switch off
automatically when all of the folÂ
lowing condit ions have been met:
- The vehicle has already been driven.
- The engine has been turned off by the Start-
Stop-System.
- The driver's door is opened.
- The driver's seat belt is removed .
- The brake pedal is not pressed down.
- The vehicle is stationary .
In this case, the activated low beam will be reÂ
placed by the side marker lights. The side marker
lights will switch off after approximately 30 mi Â
nutes or when you lock the vehicle .
If the Start-Stop-System has
not turned off the
engine or if you have switched the Start-StopÂ
System off manually, the ignition will
not be auÂ
tomatically switched off and the engine will conÂ
tinue to run~,&. .

The speed warning system helps you to keep your
driving speed below a set speed limit.
The speed warning sys tem warns if the driver exÂ
ceeds a prev iously stored maximum speed. A
warning tone will sound as soon as the vehicle
speed exceeds t he set speed by abo ut
3 mph
(3 km/h). At the same time, a warning sym bol
appe ars in t he display . Th e symbol's appea ran ce
might be different in some models .
The spe ed wa rni ng system has

play in your vehicle .
The speed is kept constant by modifying engine
power or through an active brake intervention.
A WARNING
- Always pay attention to the traffic around
you when the cruise control is in operation .
You are always responsible for 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 trafÂ
fic, on twisting roads and when road condiÂ
tions are poor (such as ice, fog, gravel,
heavy rain and hydroplaning) -you could
have an accident.
- Switch the cruise control off temporarily
when driving in turning lanes, highway exits
or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal causes
cruise control not to brake. This is due to the
control system being overridden by the drivÂ
er's acceleration.
- Never use the cruise control when driving
off-road or on unpaved roads . The cruise
control is intended for use only when the veÂ
hicle is being operated on paved roads, and
is not suitable for use off-road or on unÂ
paved roads.
- If a brake system malfunction such as over heating occurs when the cruise control sysÂ
tem is switched on, the braking function in
the system may be switched off. The other
cruise control functions remain active as
long as the indicator
light[ij;11 )~1~ (US modÂ
el)/lil (Canadian model) is on.

(D Tips
The brake lights illuminate as soon as the
brakes apply automatically.
Changing speed
"'To increase/decrease the speed in increments,
tap the lever in the
010 direction ¢ page 95,
fig . 108.
"'To increase/decrease the speed quickly, hold
the lever in the
010 direction until the deÂ
sired speed is displayed.
You can also press the accelerator pedal down to increase your speed, e .g . if you want to pass
someone . The speed you saved earlier will reÂ
sume as soon as you let off of the accelerator
pedal.
If, however, you exceed your saved speed by
S mph (10 km/h) for longer than 5 minutes, the
cruise control will be turned off temporarily. The
green symbol in the display turns white, the
saved speed is retained.

Hybrid drive
Introduction
App lies to veh icles: w ith hybr id drive
Gener al inf orm ation
The hybr id drive is a combined drive concept that
automatically switches between combustion enÂ
g ine and electr ic drive types or combines them.
All work on h igh voltage systems is intended only
for h igh voltage technicians and may only be perÂ
formed by authorized service facilities in accordÂ
ance w ith Aud i regulations.
The high voltage system is composed of the fol lowing h igh voltage components: the h igh voltÂ
age battery, the power electronics, the e lectr ic
motor, the h igh voltage A/C compressor and the
orange h igh vo ltage w iring.
High volta ge battery
The high voltage battery is located in the luggage
compartment underneath the cargo floor . You do
not need to perform any maintenance work on
the high voltage battery. Additional information
about the h igh vo ltage battery can be found unÂ
der
r::!v page 105 .
The high voltage battery service plug is a lso
found underneath an orange cover under the ca rÂ
go floo r. T he service plug is provided on ly for use
by service personne l and must not be removed by
others who are not trained to use it .
A WARNING
The voltage in the high voltage system is lifeÂ
threatening. Touching a damaged high vo ltÂ
age component can result in a fatal electric
shock. The components in the high voltage
system are marked w ith a warning label wh ich
warns against the h igh voltage.
- Never perform work on orange h igh voltage
cables or on high voltage components. Only
authorized repair facilities that are certified
may perform wo rk on the high voltage sysÂ
tem.
98
- Never open or remove the service plug cover
in the center of the cargo floor.
- Never damage, alter o r remove the orange
high voltage cable or disconnect it from the
high voltage system.
- Aud i regu lations must be followed during
all work performed on the high voltage sysÂ
tem and high voltage components.
A WARNING
While in electric dr ive mode, the veh icle proÂ
duces considerab ly less id ling, driving and opÂ
erat ing no ise than when the combustion enÂ
g ine is running. This may make it difficult or
impossible fo r othe rs such as pedes trians and
chi ld ren to hear and notice the veh icle when it
is in electrical drive mode . This can lead to
collisions and inj uries, for example in low traf Â
fic areas, when maneuvering or when driving
in reverse.
A WARNING
Never leave the vehicle unattended whi le in
the drive ready mode. The vehicle could begin moving if the accelerator peda l is pressed,
even if the combustion engine is switched off .
This may cause collisions and severe or fatal injuries. When the vehicle enters dr ive ready
mode, the status message
h• .,rid ii J apÂ
pears br iefly in the instrumen t cluster display
and the needle in the powe r meter points to
READ Y ¢ page 99.
-When exi ting the vehicle, make sure these Â
lecto r lever is i n the P position, the ignition
is switched off and the hybrid system is deÂ
activated.
(D Note
- T he h igh voltage system can be damaged if
the vehicle underbody comes into contact
with the ground. Immediate ly drive your veÂ
hicle to an authorized repair facility and
have it inspected.
- Do not transport fluids in open containers in
the luggage compartment. Spill ed fluids
can seep underneath the cargo floor. This
can damage the high voltage system.

indicator light in the button will turn on. The
• indicator light also turns on in the instruÂ
ment cluster display.
The functions and operating modes described beÂ
low are selected automatically by the veh icle conÂ
trol system, depending on the vehicle operating
status. This ensures that the vehicle is always in
the correct operating mode. One exception is the
enhanced elect ric driving mode
(E V mode), which
is activated by the driver ¢
page 101.
Driving with the combustion engine
The vehicle is powered by the combustion engine.
The high voltage battery is charged simultaneÂ
ously, if needed.
Full acceleration (boost)
In full acceleration, the vehicle is powered by
both the combustion eng ine and the electric moÂ
tor . This operating mode is called
Boost and is
only available for a short amount of time because
i t uses so much energy. Availability depends on
the high voltage battery charge level.
The boost operating mode is activated by press in g the accelerator peda l all the way down.
Electric driving
The vehicle can be driven completely electrically
depending on the high voltage battery charge
level and the driving res istance . The combustion
engine turns off at that t ime .
Hybrid
The combustion engine starts when accelerating
or when the high voltage battery charge level drops below a certain thresho ld. The vehicle reÂ
sumes electric driving once the acceleration and
the high voltage battery charge level permit .
Enhanced electric driving mode (EV mode)
Pressing the 1~· 1 button r::!> fig. 111 can extend the
usual limits on e lectric driving so that you can a lÂ
ways drive in electric mode, if the condition of
the electrical system permits. The operating
mode is then set to maximum electric drive @,
@ <:!> page 99, fig . 110. It can be driven comÂ
pletely electrically for up to 1.8 miles (3 km) at a
constant
37 mph (60 km/h).
The following conditions must be met to activate
the enhanced electric drive:
- The high voltage battery must be sufficiently
charged.
- The temperature of the
12 volt batteries and
the high voltage battery must be sufficient.
- The vehicle speed must not be higher than
62 mph (100 km/h).
- The transmission must not be in tiptronic
mode.
- Offroad mode and hill descent assist must not
be turned on

Hybrid
St art-Stop function
The combust ion engine is operated only as needÂ
ed . Genera lly, the combustion engine turns
off
when the vehicle is stationary and the high voltÂ
age battery powers the electrical vehicle sysÂ
tems .
The purpose o f automatica lly shutting the comÂ
bustion engine
off in hybrid drive mode is to save
fue l. All of the important vehicle systems, such
as steering, brakes and the A/C system, contin ue
to remain active. In some cases, systems may reÂ
qu ire the combustion engine to continue running
when the vehicle is stationary. When driv ing in
congested traffic for long periods of t i me, the
combustion engine will cycle on when the veh icle
is stationa ry to keep the h igh voltage battery
charged .
Gliding
If the gas pedal is not pressed and the D position
is selected, the combustion engine rema ins
turned
off up to speeds of approximate ly 99 mph
(160 km/h). Dr iving conse rvative ly like this can
r educe fue l consumpt ion.
Energy recovery (recup eration )
When braking, the e lectr ic motor will act as a
generator creating electric energy that is then
s to red in the h igh voltage batte ry. This also ocÂ
curs when the ve hicle is coas ting or dr iv ing downÂ
hi ll. The combust ion engine is automatically
turned
off in t his case.

k inet ic energy is recovered and may be stored as
electric energy in the high voltage batte ry. Dur Â
i ng heavy braking, the convent ional brakes are alÂ
so act ivated

Automatic start of the combu stion engine
Various operating conditions cause the combus Â
tion eng ine to start a utomatica lly :
- T he high vo ltage battery charge leve l is low.
- T he temperature of the combustion engi ne is
low.
- Th e temperature of the cataly tic converte r is
low.
- T he power output needed for the A/C system is
high.
- T he veh icle speed is high .
- The vehicle acceleration is h igh .
- The incline is steep.
- High charge level for the high voltage battery
when coasting. In this case, the hig h voltage
battery cannot absorb any more ene rgy and so
the electric motor cannot s low down the veh iÂ
cle. The combustion engine tur ns on (eng ine
brake) . In this situation the high voltage batÂ
tery will show a Max cha rge.
