Rear light defective AUDI Q2 2021 Owner´s Manual

Towing a trailer
Tyre pressure
Check the tyre pressures on your car, and adjust
for "full
load"
conditions (refer to the sticker list­
ing the tyre pressures)
^>page
307. It may also
be necessary to adjust the tyre pressures on the
trailer according to the recommendations of the
trailer manufacturer.
Exterior mirrors
Check whether you can see enough of the road
behind the trailer with the standard mirrors. If
this is not the case you should have additional
mirrors fitted. Both exterior mirrors should be
mounted on hinged extension brackets. Adjust
the mirrors to give sufficient vision to the rear.
Headlights
Before starting
a
journey, check the headlight
beam settings with the trailer hitched up. Adjust
the headlight settings if necessary.
On vehicles with halogen headlights, the
head­

light range control must be adjusted, see

tapage
49.
The headlight range control will be adjusted au­
tomatically if your vehicle is equipped with LED
headlights*.
Power supply
To ensure that the engine can be started again
after the ignition is switched off, the power
man­

agement system
^>page
149 controls the distri­
bution of electrical power and gradually switches
off unnecessary electrical equipment. The trailer
is supplied with power during this period. The
power supply to the trailer is interrupted while
the engine is being started.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket are
equipped with a removable
ball
joint coupling.
This is stored in the spare wheel well or in a sepa­
rate bag on the floor of the luggage compart­
ment, together with the necessary fitting instruc­

tions.

We recommend having the car serviced be­
tween the normal inspection intervals if it
used frequently for towing a trailer.
Trailer stabilisation system
Applies to: vehicles with towing bracket
Trailer stabilisation helps to reduce the risk of
the vehicle skidding when towing a
trailer.

When is the trailer stabilisation
system1'

activated?
Trailer stabilisation is active when the following
requirements are met:
- The ESC must be switched on
^>page
146 and
fully functional (no ESC malfunction).
- The trailer connector must be properly secured
in the vehicle socket.
- The vehicle speed must be higher than approx.
60 km/h.
How trailer stabilisation works
In many cases, the driver can stabilise a swaying
trailer by manually braking the vehicle.
However, if the ESC detects that the trailer is
swaying and this is affecting the towing vehicle,
it will automatically brake the vehicle in order to
stabilise the trailer. The indicator
Lamp Hi
will
flash in the instrument cluster. If possible, do
not turn the steering wheel at this stage.
In order to warn traffic behind you, the brake
lights will come on during this automatic braking

operation.

A trailer may sway quite considerably without the
trailer stabilisation system intervening.
If the system for activating the trailer brake
lights is defective, this will be indicated in the in­
strument cluster display
