(D Tips
It may be necessary for the gasoline engine to
r u n longer for technical reasons, such as
when condensation accumu lates in the en­
gine. Driving exclusively in electric mode is
not possible in this phase.
Plug-in hybrid functions
Applies to: vehicles with plug-in hybrid drive
The funct ions descr ibed below act ivate automati­
cally depending on the driv ing sty le.
Full-throttle acceleration (boost)
The boost funct ion is act ivated by pressing the
accelerator pedal farther down (kick-down). The
vehicle is powered by both the gasoline engine
and the electric motor when in full accelerat io n.
Boost is only availab le for a sho rt time , because it
uses a large amou nt of energy. Ava ilability de­
pends on the high-voltage battery charge level.
Coasting
The gasoline engine switches off and disengages
at speeds up to approximate ly 112 mph

ed and the "D" position is selected. Driving con­
servative ly like this can reduce fuel consumption .
Energy recovery (recuperation)
When braking, t he e lectr ic moto r will act as a
generato r creat ing elect ric energy that is then
stored in the hig h-voltage battery. This also o c­
curs when the vehicle is coasting or driving down ­
hill .
If the brakes are applied early and evenly, the
electric motor w ill brake the vehicle @
¢
page 95, fig. 98. By doing this, a large amount
of the kinetic energy is recovered and may be
stored as electric energy in the high-voltage bat­
tery . The conventional brakes are also activated
when the brakes are pressed very hard.
The strength of recuperation can depend on the
following factors:
- If you are in tiptronic mode ¢
page 88. Or
- I f the sport dr iv ing mode "S" was se lected.
The energy recovery is shown in the energy flow
display in the instrument cluster display/Info­

Trail er to wing
Trailer towing
Driving with a trailer
General information
Your veh icle is primari ly intended for transport­
ing peop le and luggage. Howeve r, if you dr ive
with a tra iler , follow the techn ica l requirements ,
the operation and driving tips, and the lega l reg ­
ulations.
Dr iving w ith a trailer affects the vehicle 's fuel
consumpt ion, performance and wear. It a lso re­
quires higher concentration from the driver .
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury .
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removab le ball
h itch mount and ball h itch. The tra ile r hitc h must
be pe rm it t ed for the vehicle, the tra iler and the
permitted tota l weight of the trailer being
pu lled . Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mo unt a t rai ler hitch on the bumper. The
trai ler hitc h must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regu larly if the trai ler hitc h is securely
mounted . A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If t he tra ile r has its own bra ke system, then fol­
low the manufacturer specifica tions. Howeve r,
the brake system on the trai ler must never be
connected to the vehicle brake system.
118
Engine cooling system
D riving w ith a tra ile r means a higher load on t he
engine and the cooling sys tem. The coo ling sys­
tem must be designed for additiona l load and
contain enoug h
coolant ¢@ .
@ Note
Longer incl ines cannot be driven wi tho ut a
suitab le cooling system, especia lly if the out ­
side temperatures are high . ot herwise, this
i ncreases the risk of eng ine damage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
Yo ur vehicle can only be ope ra ted with class 1 or
class 2 trai le rs.
Load distribution
Poor cargo load and distr ib ution can negatively
i mpact vehicle handling . T o have the lowest im­
pact as poss ible, load the tra ile r according to
t h ese cr ite ria :
- Store objects preferably in the vehicle luggage
compartment . The vehicle should a lways carry
the heaviest poss ib le load and the trailer
should have t he lig htest poss ible load .
- Dist ribute the load in the t railer so that the
heavy objects a re as close to the axle as poss i­
ble.
- Secu re objects from s lid ing o ut of place.
- Ut il ize the maximum permitted tongue we ight
if poss ible .
Tire s
Set the tire pressure on your vehicle for a "full
load"; see the tire pressure
st icker ¢ page 341.
If necessary, also adjust the t ire pressure on the
trailer acco rding to the manufactu rer's recom­
mendat ion.
Winter tires should be mounted on the vehicle and on the trailer during w inter temperatures .

Ass is tanc e system s
-your vehicle is traveling at speeds between ap ­
proximately 20 to 50 mph (30 to 85 km/h) and
it approaches a stationary vehicle.
- your vehicle is traveling at speeds between ap ­
proximately 20 to 155 mph (30 to 250 km/h)
and it approaches a vehicle that is clearly trav ­
eling more slowly or a veh icle in your direction
o f travel tha t is stopped.
When this warning occurs, it may only be possi ­
b le to avoid a collision by swerving or braking
strong ly. The message
A udi pre sense.
¢ fig. 134 and a warning tone will warn you
about the danger .
If there is an impending collision with vehicles,
there will a lso be an
acute warning in the form of
sharp braking. If you do not react to the acute
warn ing, pre sense front can brake with increas ­
ing force within the limits of the system . T his re­
duces the vehicle speed in the event of a coll i­
sion .
Autom atic deceleration
Depending on the speed, pre sense front can de­
cel erate automatica lly
shortly before a collision:
-if there are stationary vehicles when you are
traveling at speeds up to approx imately 28
mph (45 km/h)
-if there are veh icles dr iv ing or stopped ahead
whe n you are traveling at speeds up to approxi­
mately 155 mph (250 km/h)
Autom atic bra king force inc rea se
If pre sense front determines that you are not
braking strongly enough when a co llision is imm i­
nent, it can inc rease the braking force, depending
on the situation and speed:
-if there are stationary vehicles when you are
traveling at speeds up to approx imately 50
mph (85 km/h)
-if the re are ve hicles driving or stopped ahead
when you are traveling at speeds up to approxi­
mately 155 mph (250 km/h)
A WARNING
Pre sense front cannot ove rcome the laws of
physics . It i s a system des igned to assist and
132
it cannot prevent a coll is io n in eve ry ci rc u m ­
stance . The driver m ust always intervene. The
driver is always respons ible for braking at the
correct time . Do not let the inc reased safety
provided tempt yo u into tak ing risks . This
could inc rease your r isk of a co llision.
-Keep in mind that pre sense front can pro­
vide war nings or b rake unexpectedly. Al­
ways secure a ny cargo or objects that yo u
a re transporting to reduce t he ris k of dam­
a ge or inj ury.
-The system can dep loy in co rre ctly due to
sys tem -specific li mits.
-Please note that the se nsor does not a lways
detect a ll obje cts. Thi s increases the r is k of
a c ollision .
-Pre sense front does not rea ct to ve hicles
tr ave ling towa rd yo u in the same lane, to
peop le, groups of people, anim als, ob je cts
that are crossing the road, or objects t hat
are difficult to
detect ¢.& in General infor­
mation on page 124 .
A WARNING
Pre sense front may be restricted o r not avai l­
ab le in the fo llow ing example s ituations :
-if there a re othe r reflective objects nearby,
such as gua rd ra ils or vehicles
-when driving into a tunnel
-in heavy fog, ra in, sp ray o r snow
-if the rada r senso r is d irty, covered in ice,
d amaged, or cove red
- in curves
- if the ESC was restr icted or sw itched off
