2015 AUDI Q3 warning lights

164 Driving and en vironm ent
The amount of oil used is related to eng ine
load and speed.
I t is normal for the oil consumption of a new
engine to reach its lowest val ue after a certain
mileage has been driven.
You must drive your vehicle about 3 ,000 miles
(5,000 kilometers) before you can properly
assess o il cons umption .
This a lso applies to fuel consumption and en­
g ine output .
0 Note
-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your War ranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as imp roper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not a lter or remove any component of
the Emi ssion Contro l System unless ap­
proved
by the manufacturer.
- Do not a lter or remove any device, such
as heat shields, switches, ignition wires,
va lves, which are designed to protect
your vehicle's Emiss ion Control System
and other important veh icle compo­
nents .
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
• Try to avo id driving sho rt distances with a
cold eng ine.
The engine and catalytic converter have to reach their optimal
ope rating tempe ratu re to
reduce fuel con sumption and noxious emis­
sions effect ively.
Just after starting, a cold engine in a mid-size car on ly achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km) . After about a
half a m ile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2. 5 miles (4 km), the engine is at its proper operating tempera
­
ture and fuel economy has reached a normal
l evel. So you can see that you should avo id
short trips whenever possible.
T he
out sid e tempe rature is also critical in this
regard . Your car consumes more fue l in the
winter than in the s ummer.
Driving offroad
General information
When driving off road, the functions fo r the
electron ic stabiliza tion control ( ESC) are ex­
panded . The ESC-Offroad-Mode can be activat­
ed in driving situations in which a wheel lock
or a differential lock function is needed

166 Trailer towing
Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trai ler, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Tr aile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
ble for your vehicle and trailer and mu st be
mounted securely on the veh icle's chassis at a
technically sound location. Use only a trailer
h itch with a removab le ball mount. A lways
check with the trai ler h itch manufact urer to
make sure that you are using the correct
hitch.
Do not use a bumper hi tch .
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system . No modifications should
be made to the vehicle exhaust and brake sys­
tems . From t ime to time, check that all hitch
mounting bo lts remain securely fastened.
When you are not towing a trailer, remove the
trailer h itch ball mount. This prevents the
h itch from causing damage should your veh i­
cle be struck from behind
¢ A .
Traile r brak es
If your tra iler is equipped w ith a braking sys­
tem, check to be sure that it conforms to a ll
regulat ions . The trailer hydraulic brake system must not be
direct ly connected to the vehicle's hydraulic
brake system
~ A .
Saf ety ch ain s
Always use safety chains between your veh icle
and the trai le r.
Trail er light s
Trailer lights must meet all regulations. Be
sure to check w ith your authorized Audi dealer
for correct wi ring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you
us ing the regular outside mirrors, then you
must install extended mirrors .
It is important
that you always have clea r vis io n to the rear.
,8. WARNING
- I f a trai ler has electrical brakes p lease
note that these brakes are not activated
by the factory -fitted control unit -risk of
accident!
- Afte r removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or your passengers.
- Never install a "weight distributing" or
"load equalizing" trailer hitch on your ve­
h icle. The vehicle was not designed for
these kinds of trailer h itches. The h itch
attachment can fail, caus ing the trailer
to tear loose from the veh icle.
- The Gross Vehicle Weight Rating for your
veh icle, found on the safety compliance
label on the driver's s ide B-pillar, must
never be exceeded under any c ircumstan­
ces. Exceeding the Gross Vehicle Weight
Rating of yo ur vehicle is likely to damage
your vehicle, and such damage will not
be covered by yo ur Limited New Ve hicle
Warranty . Exceeding the Gross Vehicle
Weight Rating will a lso change the per­
formance and handling characteristics of
your veh icle, wh ich could cause a crash
resulting in serious injury or death.

of accidents .
- To reduce the r isk of cuts, protect your­
self from sharp metal components when
wash ing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fect may be de layed due to moisture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applications.
([) Note
-If you wash the vehicle in an automatic
car wash, you must fold the exterior m ir­
rors in to reduce the ris k of damage to
the mirrors. Power folding exterior mir ­
rors* must only be folded in and out us ­

To prevent paint damage, do not wash
the vehicle in direct sunlight.
- To reduce the risk of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the
surface, do not use polishing agents or
hard wax.
- Never use car wash cycles that apply
protective wax.
It can destroy the
matte finish effect .
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith
matte fin ish paint. The paint could be
damaged when the stickers or magnets
are removed.

D am ag e or m alfun ction s due to lack of
ma intenanc e
It is essential that you change your oil at the
r ecommended inte rva ls using only engine o il
t hat complies wi th A udi oi l standard
VW 502 00 . Your Limited New Vehicle War ­
ranty does not cover damage or malfunctions
d ue to fa ilure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manua l and Warranty
&
Maintenance book let . Your dea ler will have to
deny warranty coverage u nless you present to
the dea ler p roof in the fo rm of Serv ice or Re­
pa ir Orde rs that all s chedu led maintenance
wa s pe rformed in a t imely manner .
Engine oil consumption
The engine in your vehicle dep ends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective lubrication and
cool ing of i nternal engine components, a ll in­
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
c::;, page 161) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized.
Under norma l conditions, the rate of oil con ­
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the amb ient
temperature and road condit ions. Furthe r fac­
tors ar e the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is s ubje ct to
Checkin g and fillin g 183
wear as m ileage builds up, the oil consump ­
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
E\I in the instrument cl uster lights up, you
sho uld check the oil leve l as soon as possib le
c::;, page 184. Top off the oil at your earliest
convenience
c::;, page 184.
A WARNING
Before you c heck anythi ng i n the engine
com partment, always read a nd heed all
WARNINGS
c::;, .&. in Working in th e engine
c ompartment on page 179.
(D Note
D riving w ith an insufficient o il level is like­
ly to cause sever e damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indicator of the oil le vel. Do not
re ly on it. In stead, check the oil level in
your engine at regular intervals, pref­ erably ea ch time you refuel, and alway s
before going on a long trip .
-If you have the impression you r engi ne
c ons umes ex ce ss ive amoun ts of o il, we
recommend that you consu lt an author ­
ized Aud i dea ler to have the cause of
your concern properly d iagnosed. Keep in
m ind that the accurate measu rement of
oil consumption requ ires great care and
may take some t ime. An authorized Aud i
dealer has instructions about how to
measu re oil consumption accurately.

Battery
General information
Unde r normal operating conditions, the bat ­
tery in your A udi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the elect ro lyte level checked by an authorized
Aud i dea ler o r qualified workshop . The elec­
trolyte leve l sho uld a lso be c hecked each t ime
the battery is c harged
c::> page 192.
H ave the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a bat tery that is older tha n 5 yea rs .
W ith certa in types of a irbag deployment, t he
battery is d isconnected from the vehicle elec­
tr ica l system fo r safety reasons

Disconnecting the battery terminals
Some veh icle functions (power w indow regu­
lato rs, for example) are lost if the battery ter­
m inals a re discon nected. These functions have
to be re lea rned after the batte ry terminals a re
c onnec ted agai n. T o prevent this, the battery
should o nly be di sconnec ted from the vehicle
e lec trica l syste m when absolu tely necess ary
for repairs.
