run flat AUDI Q2 2021 Owner´s Manual

Driving
instance when you can see that the next traffic
lights are red. This takes advantage of the engine
braking effect, reducing wear on the brakes and

tyres.
Emissions and fuel consumption will drop
to zero due to the overrun fuel cut-off.
Change gear early to save fuel
An effective way of saving fuel is to change up
quickly through the gears. Running the engine at
high rpm in the lower gears uses an unnecessary
amount of
fuel.

Applies to: vehicles with manual gearbox
Shift up to second gear as soon as possible. If
possible, we recommend shifting up to the next
gear at approx. 2,000 rpm.
Applies to: vehicles with automatic gearbox
Press the accelerator slowly and avoid using the

"kick-down"
feature.
Avoid driving at high speed
Avoid travelling at top speed. Fuel consumption,
exhaust emissions and noise Levels all increase
very rapidly at higher speeds. Driving at moder­
ate speeds will help to save
fuel.

Do not let the engine idle for longer than
necessary
Engine idling periods are automatically reduced
on vehicles with start/stop system*. On vehicles
without a start/stop system, it is worthwhile
switching off the engine at level crossings, for in­
stance, or at traffic lights with a long red phase.
The fuel saved after about 5 seconds can be
greater than the amount of fuel needed to re­
start a warm engine (the exact fuel saving de­
pends on the engine version).
The engine takes a very long time to warm up
when it is running at idling speed. Mechanical
wear and pollutant emissions are also especially
high during this initial warm-up phase. It is
therefore best to drive off immediately after
starting the engine. Avoid running the engine at
high speed.

o
Regular servicing
Regular servicing can establish a basis for good

iS
fuel economy before you start driving. A
well-

serviced engine gives you the benefit of im­
proved fuel efficiency as well as maximum relia­
bility and an enhanced resale value. A poorly
maintained engine can consume up to ten per­
cent more fuel than necessary.
Avoid short trips
The engine and emission control system need to
reach their proper working temperature in order
to minimise fuel consumption and emissions.
A cold engine uses disproportionately more
fuel.

The engine only reaches its working temperature
after about four kilometres, when fuel consump­
tion will return to a normal level.
Check tyre pressures
Always make sure the tyres are inflated to the
correct pressures
•=>page
306 to save
fuel.
If the
tyre pressures
are
just 0.5
bar
too Low, this can
increase the fuel consumption by as much as 5
%. Due to the greater rolling resistance, under-
inflation also increases tyre wear and impairs

handling.

Do not use winter tyres all through the year; they
will increase fuel consumption by up to 10 %.
Avoid carrying unnecessary loads
Every kilo of extra weight will increase the fuel
consumption, so it is worth checking the Luggage
compartment occasionally to make sure that no
unnecessary loads are being transported.
The roof carrier increases the air resistance of the
vehicle and should be removed when not in use.
This will save about 12 % of fuel at speeds of be­
tween 60 and 75
mph.

Save electrical energy
The engine drives the alternator to generate elec­
tricity. This means that fuel consumption rises
when more power is required for electrical equip­
ment. Switch off electrical equipment when it is
not needed. Electrical equipment which uses a
lot of electricity includes the blower (at a high
setting), the rear window heating and the seat

heating*.

- Make sure you never spill fuel in the
vehi­

cle or in the luggage compartment. Fuel
vapour is explosive - danger to life!
© Note
(7) CAUTION
- If any fuel is spilt onto the vehicle, it should
be removed immediately as it could other­
wise damage the paintwork.
- Never run the tank completely dry. If there
is an irregular fuel supply, misfiring can oc­
cur. As a result unburnt fuel can enter the
exhaust system and cause damage to the
catalytic converter(s).
- Applies to vehicles with diesel engine: When
filling the fuel tank after having run it com­
pletely dry, the ignition must be switched
on for at least 30 seconds before the engine
is started. When you then start the engine it
may take longer than normal (up to one mi­
nute) for the engine to start firing. This is
because air needs to be bled from the fuel
system while starting.
® For the sake of the envir
Do not try to put in more fuel after the auto­
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm.

(T)
Note
Applies to: vehicles with diesel engine
Diesel vehicles are equipped with an incorrect
fuelling protection
system1).
This system en­
sures that the tank can only be fuelled from a
diesel filler nozzle.
- If the filler nozzle is old, damaged or too

small,
it may not be able to open the pro­
tection mechanism on the fuel tank. In this

case,
try turning the filler nozzle before in­
serting it in the fuel filler neck, use a differ­
ent filling pump or seek professional assis­

tance.

- The protection mechanism will not open if
you try to add fuel from a spare fuel canis­
ter. You can get round this simply by adding
the diesel fuel slowly.

Tyre wear / damage

A
WARNING
- Use only tyre/rim combinations and match­
ing wheel bolts approved by Audi. Otherwise
damage to the vehicLe and an accident could
result.
- For technical reasons, it is not possible to
use wheels from other vehicles. In certain
cases, it is not even possible to use wheels
from another vehicle of the same model.
- It is very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not
rely entirely on the nominal tyre size
marked on the tyre; with some makes of
tyre the effective tyre size can differ signifi­
cantly from the nominal dimensions, even
though the tyres have the same size desig­

nation.
Inadequate tyre clearance can result
in damage to the tyres or the vehicle, caus­
ing a serious safety risk.
- Avoid running the car on tyres that are more
than 6 years old. If
you
have no alternative,
you should drive slowly and with extra care
at all times.
- The use of run-flat tyres on your vehicle is
NOT authorised! Unauthorised use can cause
an accident or damage your vehicLe.
- If wheel trims are fitted after the car is pur­

chased,
ensure that there is an adequate
flow of air for cooling the brakes - risk of ac­
cident!

Tyre wear
Inspect the tyres regularly for damage.
- The wear on under or over-inflated tyres is
sig­

nificantly higher.
- Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
- If
you
notice excessive tyre wear, have the
wheel alignment checked by a qualified work­

shop.

- Have your tyres rebalanced if steering wheel vi­
brations indicate an imbalance. Otherwise, the
tyres and other parts of the vehicLe may wear
faster.
Tread wear indicators
The original tyres on your vehicle have 1.6 mm
high tread wear indicators
^>Fig.
252 running
across the tread at regular intervals. The letters

"TWI"
or triangles on the sidewall indicate the
positions of the tread wear indicators.
The minimum tread
depth1)
is reached
at
the lat­
est when the tread is worn down to the tread
wear indicators. Replace the tyres with new ones
Changing wheels round
Wheels should be changed round regularly to en­
sure that the wear is equal on all tyres. Fit the
wheels from the rear axle on the front axle and
vice-versa. All the tyres will then last for about
the same time.

Please observe the applicable regulations in the country in
which you are travelling.

will indicate its position.
Each time you change a tyre, change the wheels
round or change the tyre pressures on your
vehi­

cle (e.g. when switching from partial load to full
load and vice-versa), you must store the new tyre
pressures in the menu display

Mon­

itoring of the tyre pressures is based on the tyre
pressures you have stored. The inflation pres­
sures recommended for your vehicle are given on
the tyre pressure sticker

The rolling circumference and vibration can
change and cause a tyre pressure warning if:
- The inflation pressure in one or more tyres is
too low.
- The tyre has suffered structural damage.
- The wheels were changed or the tyre pressures
were changed and the new tyre pressures were
not stored

- The vehicLe load is not balanced (more load on
one side).
- There is more load on the wheels of one of the
axles (e.g. when towing a trailer or driving up
or down a gradient).
- You are driving with snow chains.
- You are driving with the temporary spare

wheel*.

- Only one wheel of an axle has been changed.

these tyres.
- The tyre pressure Loss indicator can only
monitor the pressures of the tyres fitted on
the car. For this reason please regularly
check the tyre pressure of the spare wheel
in the luggage compartment so it can be
used if required.

A
WARNING
- If the tyre pressure loss indicator appears in
the instrument cluster display, slow down
immediately and avoid any severe braking or
steering manoeuvres. As soon as you can do
so safely, stop and check the tyres and the
tyre pressures.
- It is the driver's responsibility to ensure that
the tyre pressures are correct. For this rea­
son you must check the tyre pressures
regu­

larly.
- Under certain conditions (e.g. driving at
high speeds, on ice and snow or on poor
road surfaces) the tyre pressure loss indica­
tor may not appear immediately.
- The use of run-flat tyres on your vehicLe is
NOT authorised! Unauthorised use can cause
an accident or damage your vehicle.
