2021 AUDI Q2 warning lights

Driving
Driving off with the hold assist
Applies to: vehicles with hold assist
The hold assist helps the driver if the vehicle is
stationary for a Long period or very often, for in­
stance at traffic lights, on steep gradients or in
stop-and-go traffic.
Important: The driver's door must be closed and
the engine must be running.
• To switch the hold assist on/off, press the but­
ton
«59 © ^>page
82, Fig. 74,
•=»^.
The LED in
the button will light up or go out.

•
Once it detects that the vehicle has stopped,
the hold assist keeps the vehicle stationary. In
this case, a green indicator Lamp
^
Lights up in
the instrument cluster. You can now take your

foot
off the brake pedal.

•
Drive off in the normal way: the brake will be
released automatically and the vehicle will
start moving.
In certain situations, the hold assist transfers the
job of holding the vehicle to the parking brake.
As soon as the parking brake is holding the
vehi­

cle
still,
the warning lamp || appears in the in­
strument cluster. In addition, the LED in the ®)
button will light up.

Hold assist: unavailable
If this message appears, the hold assist is un­
available or the system requirements have not
been met.
A WARNING
Applies to: vehicles with hill hold assist
If
you
do not drive away immediately after re­
leasing the brake pedal, or if the engine

stalls,
the vehicle could start to roll back. You
should therefore immediately press the brake
pedal or apply the parking brake.
A WARNING
The intelligent technology in the hold assist*
and hill hold assist functions cannot defy the
laws of physics. Do not let the extra conven­
ience afforded by the hold assist* and hill
hold assist functions tempt you into taking
any risks when driving - this can cause
acci­

dents.

- The hold assist* and hill hold assist func­
tions cannot keep the vehicle stationary in
all conditions on a gradient (e.g. if the road
is slippery or icy).
- Always ensure that the vehicle is stopped
properly and safely - risk of accident!

(T)
CAUTION
Switch off the hold assist* function before
driving the vehicle into a car wash.

Note
Applies to: vehicles with automatic gearbox
When the hold assist* function is switched

on,
it stops the vehicle from creeping for­
wards when you take
your
foot off the brake

pedal.

Off-road driving
General notes
The functions of the electronic stabilisation
con­

trol (ESC) have been augmented to provide extra
assistance when driving off-road. The
ESC
off-
road mode can be activated in situations when it
would be advantageous for the wheels to lock, or
when a differential Lock would normally be re­
quired
^>page
146.
This Audi model is not an off-road vehicle, how­
ever. When driving off-road you are advised to
avoid tracks or terrain which are not suited to
the design of the car and your own driving skills
and experience. Do not take any risks.
After driving off-road
- After driving, remove any pieces of foliage or
other objects which may be caught in the radia­
tor grille, under the car or in the wheels. In par­
ticular, inspect the tyre treads for stones.
- Clean the bodywork and underside of the
vehi­

cle and check the underside for possible dam­

age.

- Remove dirt from the windows, headlight
len­

ses and number plates. •

Driving
A WARNING
- The driver should never get out of the
vehi­

cle when the engine is running and a gear is

engaged.
If you have to leave your vehicle
while the engine is running, you must apply
the parking brake and engage the parking
lock P.
-If the engine is running and a gear is engag­
ed (D/S or R) or the vehicle is in "tiptronic"

mode,
you will need to hold the car with the
footbrake. Otherwise, the car will "creep"
forwards as the power transmission is not
fully interrupted even when the engine is

idling.

- The accelerator pedal must on no account
be pressed inadvertently when the vehicle is
stationary. The vehicle could otherwise start
moving immediately (in some cases even if
the parking brake is engaged) and possibly
cause an accident.
- Do not press the accelerator while selecting
a gear with the vehicle stationary and the
engine running, as this could cause an
acci­

dent.
- Never move the selector lever to R or P
when driving at normal speeds, as this could
cause an accident.
- Before you drive down a steep gradient, re­
duce the speed and use "tiptronic" to select
a low gear.
- Never allow the brake to drag when driving
downhill and do not use the brake pedal too
often
or
for long periods. Constant braking
will cause the brakes to overheat and will
considerably reduce the effectiveness of the
brakes. It will increase the braking distance
and could cause the brake system to
fail.

- To avoid rolling back on gradients always
hold the vehicLe with the footbrake or park­
ing brake if you have to stop.
- Never attempt to hold the vehicle with the
clutch when stopping on a gradient. The
clutch is disengaged automatically if it is
overloaded and becomes too hot - accident
risk! If the clutch is overloaded, the indica­
tor lamp
0
will light up and a message will
appear
^>page
92.
© CAUTION
- When you have stopped on a gradient, do
not try to stop the vehicle rolling back by ac­
celerating when a gear is engaged. This
could cause the automatic gearbox to over­
heat and become damaged. Apply the park­
ing brake or press the brake pedal in order
to prevent the vehicle from rolling back.
- If you allow the car to roll with the selector
lever in position N with the engine switched
off, the automatic gearbox will be damaged
as it will not be lubricated
^page

Tow-starting / towing
away.

- In certain driving and traffic conditions, for
instance in stop-and-go traffic, if you have
to pull away frequently or if the vehicle
creeps forwards over a long distance, the
gearbox can overheat and become dam­

aged.
If the indicator Lamp
[5J
or the warn­
ing
lampH
Lights up, stop the vehicle at
the first opportunity and let the gearbox
cool down
^>page

© Note
For safety reasons the parking brake will only
release automatically if the driver's door is

closed.

Downhill speed control
Applies to: vehicles with automatic gearbox
The downhill speed control function helps the
driver when driving down steep gradients.
Downhill speed control is activated on a downhill
gradient when the selector lever is in D/S and the
driver presses the brake pedal. The gearbox auto­
matically selects a suitable gear for the gradient.
The downhill speed control function attempts to
maintain the speed at which the vehicLe was trav­
elling when the foot brake was applied (subject
to the laws of physics and technical limitations of
the power train). It may be necessary to adjust
the speed again using the foot brake. The down­
hill speed control can change down to 3rd gear
but no further, so it may be necessary to change
to tiptronic mode on very steep gradients. In this

case,
change down manually to 2nd or 1st gear in •
CO

Driving

speed.
The upshift to the next higher gear is de­
layed until the engine reaches maximum rpm.
WARNING
Please note that if the road surface is slippery
or wet, the kick-down feature could cause the
driven wheels to
spin,
which could result in

skidding.

Coasting mode
Applies to: vehicles with S tronic gearbox and coasting mode
In coasting
mode1)
you can use the vehicle's mo­
mentum to freewheel, for instance when ap­
proaching a speed restriction in a built-up area.
The engine is disengaged from the gearbox. This
allows you to save fuel by anticipating the traffic
situation ahead.
Requirements for using coasting mode

•
Efficiency mode selected in drive select*

^>page
131.

*•
The selector lever must be in position D.

•
Road speed less than approx. 130 km/h.

•

A WARNING
- When coasting mode is activated, there is
no engine braking effect and the vehicle
does not slow down as quickly as usual or
may even pick up speed if
you
are driving
down a slope - risk of accident!
- If other people are using your car, you
should draw their attention to the coasting

mode.

© Note
- The gear is no longer displayed when you
are in coasting mode (e.g.
E
instead of E7).
- The coasting mode is deactivated tempora­
rily on gradients of
15
% or greater.
- Coasting mode is not available while the
cruise control system* or adaptive cruise

control*
is switched on.

Towing a trailer
Towing a trailer
Driving the vehicle with a
trailer or caravan
Technical requirements

The
towing bracket must comply with certain
technical requirements.
Your car is intended mainly for transporting pas­
sengers and luggage. However, if suitably equip­

ped,
it can also be used to tow a trailer or cara­

van.

If the car is supplied with a factory-fitted towing
bracket it will already have the necessary techni­
cal modifications and meet the statutory require­
ments.
A 13-pin socket is provided to make the electrical
connection between the car and the trailer. If the
trailer you wish to tow has a 7-pin plug, the nec­
essary adapter cable can be obtained from a spe­
cialist retailer.
If
a
towing bracket is to be fitted after the car is

purchased,
this must be done according to the in­
structions of the towing bracket manufacturer

^page
102.
A WARNING
If
a
towing bracket is retrofitted, the installa­
tion should be carried out by
a
qualified work­

shop.

- In particular in high outside temperatures it
is not possible to drive up long steep gradi­
ents without
a
suitable cooling system. The
engine would then overheat.
- Incorrect installation can result in a safety
risk.
Points to check before towing
There are a number of points which need to be
checked before towing a trailer or caravan.

*•
Observe the maximum permitted trailer
weights
^>page
342.
Trailer weights
Never exceed the maximum permitted trailer
weights.
If
you
do not load the trailer up to the maximum
permitted trailer weight, you can then climb cor­
respondingly steeper gradients.
The maximum trailer weights listed are only ap­
plicable for altitudes up to 1000 m above sea

level.
With increasing altitude the engine power
and therefore the car's climbing ability are im­
paired because of the reduced air density, so the
maximum trailer weight has to be reduced ac­
cordingly. The weight of the car and trailer must
be reduced by about 10% for every further
1000 m (or part thereof). This figure refers to
the combined weight of the (loaded) vehicle and
(Loaded) trailer.
The figures for the draw bar weight that appear
on the identification plate of the towing bracket
are for certification purposes only. The correct
figures for your specific model, which may be
lower than these figures for the towing bracket,
are given in the registration documents and in

•=>
page 343.
Drive select*
Please note that the
efficiency*
mode is not
available in towing mode.
Exterior lights
Before starting
a
journey, make sure that all the
lights for the trailer are working properly.
Distributing the load
Distribute loads in the trailer so that heavy ob­
jects are as near to the axle as possible. Loads
carried in the trailer must be secured to prevent
them slipping. A badly distributed load can also
affect handling. This can activate the trailer sta­
bilisation feature and cause the vehicle to reduce

speed.

Where possible, operate the trailer with the max­
imum permitted draw bar weight on the ball
joint of the towing bracket, but do not exceed the
specified limit. •

Automatic deactivation
Cruise control system: currently unavailable.
See owner's manual
The cruise control system has been automatically
deactivated because the system has detected a
fault which could impair its function. Try switch­
ing the cruise control system on again later.
A WARNING
Do not resume the programmed cruising
speed if this is too high
for
the traffic condi­
tions - this can cause accidents.

A WARNING
- Always direct your full attention to the
road,

even when you are using the speed limiter.
It is always the driver who is responsible for
determining the speed and for keeping a
safe distance to the other vehicles on the

road.

- For safety reasons, the speed limiter must
not be used in adverse weather or difficult
driving conditions (such as ice, fog, loose
grit or gravel, heavy
rain,
etc.) - risk of
acci­

dent!
- Only accelerate quickly or use the kick-down
feature when the visibility and weather
con­

ditions are suitable, and when the road and
traffic conditions allow you do do so safely.
Before driving down a
long,
steep gradient, it
is advisable to reduce speed and select a low­
er gear. In this way you will make use of the
engine braking effect and relieve the Load on
the brakes.

General notes
The traffic sign recognition system can detect
standardised speed Limit signs within the cam­
era's range of
vision.
It makes use of the naviga­
tion data to evaluate the detected speed limits
and show them on the display. Under certain
con­

ditions, the system will also display the legal
speed limits on roads without speed Limit signs.
The traffic sign for the currently detected speed
limit will flash on the display if
a

threshold,
which has been set on the infotain­
ment system, is exceeded
^page
109.
Traffic sign recognition is not available in all
countries. For
a
current list, see the Internet (e.g.
www.audi.com). The system is also subject to
certain inherent restrictions and may be partially
or completely unavailable in the following situa­

tions:

- If visibility is impaired by snow,
rain,
fog or
heavy road spray.
- In dazzling light, e.g. from the sun or oncom­
ing traffic.
-At high speeds.
- If the camera's range of vision
^>Fig.
98 is im­

paired,
e.g. by dirt or stickers. Notes on clean­
ing
•=>
page 312.
- If the traffic signs are partially or completely

obscured,
e.g. by trees, snow, mud or other
vehicles.
- If traffic signs deviate from the standard ap­
pearance (round with red border).
- If traffic signs are damaged or bent.
- If matrix traffic signs are mounted on overhead
gantries.
- If traffic signs or routes have changed (naviga­
tion data out of date).
- If the system detects a speed sticker on a slow-
moving vehicle (such as a heavy goods vehicle).
WARNING
Always direct your full attention to the road
and surroundings, even when you are using
traffic sign recognition. The actual traffic
signs on your route always take precedence

over
the information on the display. It is al­
ways the driver's responsibility to assess the
traffic situation and take appropriate care.
- Under adverse conditions, the traffic sign
recognition system may misinterpret or fail
to detect traffic signs. It is therefore possi­
ble that the speed limit display may occa­
sionally be unavailable or even incorrect.

Audi adaptive cruise
control
Description
Applies to: vehicles with Audi adaptive cruise control

»

Fig.
100 Sensor range
The adaptive cruise control is a combined speed
and distance control system. It assists the driver
by controlling the road speed and the distance to
the vehicle in front within certain limits imposed
by the system. The adaptive cruise control sys­
tem can accelerate and brake when it detects a
vehicle in front. This provides maximum comfort
both on long motorway journeys and in conges­
ted traffic (automatic gearbox*).
What can the adaptive cruise control do?
The adaptive cruise control uses a radar. The ra­
dar is subject to certain system limitations

opage
112.
When there is no traffic in front, the adaptive
cruise control works just like a normal cruise
con­

trol system by maintaining a constant speed.
When you draw closer to a vehicLe in front which
is detected by the system, the adaptive cruise
control matches your speed to that vehicle by au­
tomatically applying the brakes, and then main­
tains a constant distance (which you can adjust in
the settings). As soon as it detects no more
vehicles in front, the adaptive cruise control ac­
celerates back up to the cruising speed.
Applies to: vehicles with automatic gearbox
In congested traffic, the adaptive cruise control
can brake down to a standstill and accelerate
again (subject to general system limitations) un­
der certain conditions
*$page
115, Driving in
congested traffic. The traffic jam assist (active
lane assist)* can assist the driver in traffic jams
and heavy congestion

Which functions can the driver control?
When you switch on the adaptive cruise control,
you can set your current speed as the "cruising

speed"
