General notes
Running in
A new vehicle should be run in over a distance of
1,500 km. For the first 1,000 km the engine
speed should not exceed 2/3 of the maximum
permissible engine speed -do not use full throt­
tle. From 1,000 to 1,500 km you can gradually
increase the engine rpm and road speed.
During its first few hours of running, the internal
friction in the engine is greater than later on
when all the moving parts have bedded down.
How the vehicle is driven for the first 1,500 km
also influences the engine quality. After this peri­
od you should continue driving at moderate en­
gine speeds, in particular when the engine is
cold. This helps to reduce wear and tear on the
engine and increases the potential mileage which
can be covered by the engine.
You should also avoid driving with the engine
speed too low. Change down to a lower gear
when the engine no longer runs "smoothly". Ex­
cessively high engine speeds are prevented by an
automatic rev limiter.
Letting the engine warm up/cool down
Applies to: Sand RS models
You can reduce the amount of wear and tear on
your vehicle during a sporty driving session sim­
ply by adopting a more restrained driving style
while the engine is warming up and cooling
down.
When the engine is cold, the engine speed is limi­
ted so that the full range of engine power is not
available. Once the engine has reached operating
temperature, the rev Limit moves to a higher
range of engine speeds. In addition, the tyres will
not develop their full grip potential until they
have had a chance to warm up on the road.
Even though the engine continues to be cooled
after you switch it off, it is particularly important
to give it time to cool down before parking. The
engine, brakes, exhaust system and gearbox will
66 all
reach very high temperatures when you adopt
a sporty driving style. Before you park the vehi­
cle, allow it to cool down to normal temperature
by driving at moderate engine speeds for several
miles.
Avoiding damage to the car
CD CAUTION
Take care not to damage low-mounted parts
of the car (such as the spoiler or exhaust sys­
tem) on steep ramps, uneven road surfaces or
roadside kerbs, etc. This applies especially to
vehicles with low ground clearance and to all
vehicles when fully laden.
Driving through water on roads
Please note the following in order to prevent
damage to the vehicle when driving through wa­
ter (e.g. on flooded roads):
- The water level must not be higher than the ve­
hicle's underbody.
- Do not drive faster than walking pace.
A WARNING
After driving through water, mud, sludge,
etc., the braking effect can be delayed slightly
due to moisture on the discs and brake pads.
Applying the brakes carefully several times
will remove the moisture and restore the full
braking effect.
CD CAUTION
- Parts of the vehicle (e.g. engine, gearbox,
running gear or electrical components) can
be badly damaged when driving through
water.
- Always switch off the start/stop system*
¢ page 71 before driving through water.
i Note
- It is advisable to check the depth at the
deepest point before approaching the wa­
ter.

Never spill fluids on a hot engine. These flu­
ids can cause a fire (e.g. radiator anti­
freeze).
- Take care not to cause short circuits in the
electrical system, especially when working
on the battery.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off -risk of injury!
- Do not unscrew the cap on the expansion
tank when the engine is hot. The cooling
system is under pressure.
- Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.
- Never remove the engine cover panel -risk
of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive
belts, alternator and radiator fan, etc., and
from the high-voltage ignition system.
- Vehicles with automatic gearbox: Never
open the throttle inadvertently (for instance
by hand from the engine compartment) if a
gear is engaged while the vehicle is station­
ary with the engine running. The vehicle will
otherwise start moving immediately and
could cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
- Any work on the batteries and electrical sys­
tem in your vehicle entails a risk of injury
and chemical burns in addition to danger of
accident or fire. For this reason, you must
have the work carried out by a qualified
workshop.
CD CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening. This Checking
and topping up fluids
can otherwise cause serious malfunctions or
engine damage.
@ For the sake of the environment
Inspect the ground underneath your vehicle
regularly so that any leaks are detected at an
early stage. If you find spots of oil or other
fluids, have your vehicle inspected in the
workshop.

Coolant
The engine cooling system is filled at the factory
with a mixture of conditioned water and coolant
additive. This coolant must not be changed.
The coolant level is monitored by a warning lamp
• ¢page 14. However, we recommend that it
should be checked occasionally.
If you do need to top up the coolant, use a mix­
ture of water and coolant additive. We recom­
mend mixing coolant additive with distilled wa­
ter.
Coolant additive
The coolant additive contains anti-freeze and cor­
rosion protection agent. Only use one of the fol­
lowing coolant additives. It is possible to mix
these additives.
Coolant additive Specification
G13 TL 774
J
G12++ TL 774 G
The amount of coolant additive which needs to
be mixed with the water depends on the temper­
atures to be expected in the winter season. If the
anti-freeze concentration is too low, the coolant
can freeze and cause engine damage.

CD CAUTION
- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­
pected. This applies particularly if you drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa- Checking

ble. In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
-Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.

Downloaded from www.Manualslib.com manuals search engine Checking
and topping up fluids
Any loss of coolant normally indicates a leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system
checked. If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.
A WARNING
- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be scal­
ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children -risk of poisoning.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off- risk of injury!
CD CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling
system -risk of engine damage! In this case,
do NOT drive on. Obtain professional assis­
tance.

250 Checking
brake fluid level
� Read off the brake fluid level on the brake fluid
reservoir ¢page 246, Fig. 214. The brake fluid
level must be between the MIN and MAX marks
¢_A.
The brake fluid level is also automatically moni­
tored.
Having brake fluid changed
Have the brake fluid changed regularly by a quali­
fied workshop.
A WARNING
- If the brake fluid level is under the MIN
mark, the effectiveness of the brakes and
therefore the safety of the vehicle may be
impaired -risk of accident! Do not drive on.
Obtain professional assistance.
- Heavy use of the brakes may cause a vapour
lock if old brake fluid is left in the system.
This would seriously impair the effective­
ness of the brakes and the safety of the car
- risk of accident!
CD CAUTION
- If the brake fluid level is above the MAX
mark, brake fluid may escape via the cap on
the reservoir in certain circumstances and
cause damage to the vehicle.
- Brake fluid must not be allowed to come in­
to contact with the vehicle's body, other­
wise it will attack the paintwork.
Battery General warnings for batteries
Because of the complexity of the power supply,
any battery work, such as disconnection, replace­
ment, etc. must be carried out by a qualified
workshop ¢ ,& .
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.

means, for example, that the tyre was produced
in the 22nd week of 2016.
Audi Genuine Tyres
Audi Genuine Tyres with the marking "AO" are
specially matched to your Audi. When used prop­
erly, these tyres meet the highest standards in
safety and handling. Your specialist retailer will
be glad to provide more information.
_& 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!

which you are travelling. Wheels
Tyre wear / damage
Fig. 221 Tyre tread: Tread wear indicators
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.
221 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 depth 1
) is reached at the lat­
est when the tread is worn down to the tread
wear indicators. Replace the tyres with new ones
¢ _8..
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.
