•• Drive system: system fault! Safely park
vehicle
There is a malfunction in the plug-in hybrid sys­
tem. The brake booster and the power steering
may stop working. Stop the vehicle immediately
or as soon as possible. Park the vehicle in a safe place outdoors that is not near buildings, roof
overhangs, carports or similar structures. Switch
the ignition off. Have the problem corrected by
an authorized Audi dealer or authorized Audi
Service Facility.
•• Electric drive: overheated! Safely stop
vehicle and check coolant
The coolant level is too low or the coolant tem­
perature is too high.
Stop the vehicle in the outdoors as soon as it is
safely possible. Switch the ignition off.
Read the important safety
precautions ¢.& in
Coolant on page 103
and check the coolant level
¢page 102.
If the coolant level is OK, the malfunction may be
caused by the system overheating. Let the vehi­
cle's electric drive system cool down for some
time .
If the message turns off after cooling down and
switching the ignition back on, you can continue
driving. Contact an authorized Audi dealer or au­
thorized Audi Service Facility immediately to have
the malfunction corrected.
If the indicator light stays on, contact an author­
ized Audi dealer or authorized Audi Service Facili­
ty.

It may be necessary for the gasoline engine to

when condensation accumu lates in the en­

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

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:

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 .
