2013 AUDI Q7 engine oil

-Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too
long or too often. This could cause the
brakes to get hot and dimin ish braking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when you do not intend
to brake. Th is may cause the brakes to
overheat, prema ture wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced . In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driv ing for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads w ith a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct ­
ed. Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­
est author ized Audi dealer or qualified
workshop .
Brake booster
The brake booster adds extra braking power.
The brake booster works with vacuum pres­
sure which is created only when the engine is
running¢ &,.
Int ellig ent technolog y 229
A WARNING
-Never let the veh icle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
example when towing your vehicle, or because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .
Functioning of Anti-Lock Brake System
(ABS)
ABS prevents the wheels from locking up un­
der braking.
T he ABS contributes effect ively to vehicle con­
trol s ince it preve nts the whee ls from
locking
when the brakes are applied. This means that
the vehicle remains steerable and is less likely
to skid .
With ABS y ou do not n eed to pump the
bra ke. Just h old t he br ake ped al d own .
However, do not expect the ABS to shorten
braking distance under
all circumstances.
When dr iving on g ravel or on new ly fallen
snow o n top of icy s urfaces, braking dis tance
may be even longer, therefore, under these
circumstances, it is especia lly important that
you drive s low ly and with great care.
How the ABS s ystem works
An a utomat ic check is made when a speed of
about 12 mph (20 km/h) is reached . When
th is happens, a pumping noise can be heard.
If an ind iv idual whee l begi ns to rotate too
s low ly in relation to vehicle speed and tends
to lock, the ABS automatically reduces brake
pressure to prevent that whee l from locking .
T his automatic adjustment p rocess will cause
a
sli ght vibrati on of the brake pedal and some
noises to a le rt you that ve hicle speed m ust be
adapted to existing road and traffic condi ­
tions. •

@ Tips
- When the engine is running, never hold
the steer ing whee l turned a ll the way to
the right or t o the left f or longer than 15
seconds. The power steering pump w ill
overheat the hydraulic f lu id if you keep
hol ding the steer ing wheel turned all the
way. This is likely to damage the power
steering system.
- If the power steer ing system should fail
ent irely, or if the engine is not running
(fo r example, while being towed), you
will still be ab le to steer the vehicle.
However,
considerably more effort will
be required to do so.
- If the power s teer ing system should
have a leak, or is not functioning proper­
l y, contact yo ur authorized Audi dealer
immediately.
- The power stee ring system requires a
spec ially formulated hydraulic fluid. The
power steering reservo ir is the one locat­
ed farthest to the rear on the left side of
the engine compartment
c> page 266.
The co rrect flu id level in the reservoir is
i mportant for proper functioning of the
power steer ing .
Driving with your

With all-wheel drive, oil four wheels ore driv ­
en.
Gener al information
W ith all -whee l dr ive , power is distributed to
a ll fo ur wheels. This happens automatica lly
depending on yo ur driving sty le and the road
conditions at the time . See also
¢ page 227,
Electronic differential lock (EDL) .
Winter tires
When driving in the w inter, your ve hicl e w it h
all -wheel drive has an advan tage, even with
regu lar tires . In winter road conditions it may
be advisable to mount winter tires (or all -sea­
son t ires) for improved driveability and brak-
Int ellig ent technolog y 231
ing: these tires must be mounted on all four
wheel s. See also ¢
page 295, Winter tires .
Tire chains
Where tire chains are mandatory o n certain
roads, this no rma lly also app lies to veh icles
with all-wheel drive¢
page 296, Snow
chains.
Replacing wheels /tires
Vehicles with all-wheel drive must always have ti res of t he same s ize. A lso avo id tires
with different t read depths. For det ails see
page
c!;> page 291, New tires and replacing
tires and wheels .
_& WARNING
A lways adj ust yo ur driv ing to road and traf­
f ic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
-Altho ugh the all-wheel drive is very ef­
fective, always remember that braking
capacity is lim ited by tire traction. You
should therefore not drive at excessive
speeds on icy or slippe ry road surfaces .
- On wet road surfaces, be careful not to drive too fast because the front wheels
could begin to slide o n top of the water
(aquaplaning). If th is should occur, yo u
will have no warning from a s udden in­
crease in engine speed as w ith a front ­
wheel drive vehicle. Always drive at
speeds which are suited to the road con­
ditions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventiona l energy system
is not driven for a long per iod of t ime, the bat­
te ry is discharged by idling cur rent consume rs
(e.g. immobi liz e r). In certa in circumstan ces it ..,_

Catalytic converter
Applies to vehicles: with gasoline engine
It is very important that your emission con­trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
... Always use lead-free gasoline¢ page 256,
Gasoline .
... Never run the tank down all the way to
empty .
... Never put too much motor oil in your en-
gine
¢ page 270, Adding engine oil~-
.,. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff icient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the poll utants in the exhaust gas be ­
fore they are released into the atmosphe re.
The exclusive use of unleaded fuel is cr it ically
i mportant for the life of the cata lytic convert­
e r and proper fu nctioning of the engine.
A WARNING ,~
- Do not park or operate the veh icle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con­
verter or heat shie lds . During driving, the
substance used for undercoating could
overheat and cause a fire.
{[) Note
-Be aware that just one tank fi lling with
le aded fuel will already seriously de­
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 270.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned fuel could a lso get into
Dri vin g and en vironm ent 235
the exhaust system and this cou ld cause
the catalytic converter to overheat .
- Do not turn off the igni tion while the ve ­
hicle is moving.
- Do not con tinue to ope rate your veh icle
unde r these conditions, as othe rwise fuel
can reach the catalytic converter. This
co uld result in overheating o f the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained prope rly
and in accordance w ith the se rv ice rec­
ommendat ions in you r Warranty &
M aintenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w il l impair
the function of the em ission contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing properly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f illing the tank with lead-free super
grade gasoline .
Diesel particulate filter
Applies to vehicles : with diese l eng ine
The diesel part iculate filter filters nearly all of
the soot particles out of the exhaust . The fil­
ter cleans itself automat ica lly under normal
driv ing cond itions . If the filter ca nnot clean it­
self (for example, because you a re o nly dr iving
short distances), the fi lter becomes clogged
with soot and the

A WARNING
- Do not park your vehicle over flammab le
materia ls such as grass or leaves because
the high temperature of the diesel par-
ticulate f ilter could start a fire. ..,. •

It takes a long time for the engine to warm up
fu lly when it is running at idle. However , wear
and nox ious em issions are especially high
when the engine is warming up. So you should drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
p roduces heat, which cou ld resu lt i n over­
heating or other damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
"' Have your vehicle serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
author ized Audi dealer helps to ensure that it
r uns p roper ly and economically. The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects
fuel
c on sumption.
Ch eck your oil each time you fill your tank .
The amount of oil used is related to engine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest v alue after a certain
mileage has been dr iven .
You must drive your vehicle about 3,000 miles (5,000 ki lometers) before you can properly
assess o il consumption .
This a lso applies to fuel consumption and en­
gin e output.
0 Note
- Have yo ur vehicle maintained properly
and in accordance wit h the service rec­
ommendations in your War ranty
& Main-
Dri vin g and en vironm ent 237
tenance book let. Lack of p roper mainte­
nance as well as improper use of the ve ­
hicle will impair the function of the
em ission contro l system and could lead
to damage.
- Do not alter or remove any component of the Emission Control System unless ap­proved by the manufacturer.
- Do not alter or remove any device, such as heat shie lds, switches, ign ition w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other impo rtant vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
"' Try to avoid driv ing short distances w ith a
cold engine .
The eng ine and cataly tic converter have to
reach their opt imal
operat ing temperature t o
reduce fuel consumpt ion and nox ious em is­
s ions effect ively .
Just after starting, a co ld eng ine in a mid-s iz e
car only achieves a fuel economy of 6-8 mi les
per gallon (30 -40 l/l00km). After about a
half a mile , fuel economy cl imbs to 12 mpg
(20 l/100 km) . After about
2.5 miles (4 km),
t he engine is at i ts p rope r opera ting tempe ra­
tu re and f uel economy has reached a normal
l evel. So you can see that yo u should avo id
short trips whenever possible.
T he
out sid e t emperature is also cr itica l in th is
regard. Your car consumes more fue l in the
winter than in the s ummer.

238 Driving off road
Driving off road
Driving in difficult road
conditions and offroad
General information
The operation of the E lectronic Stabilization
Control (ESC) is expanded for operation away
from paved roads. In situations where slip or a
differential locking function is required, the ESC offroad mode can be activated
c::> page 225 . Hill descent control is also availa­
ble in the ESC offroad mode, which automati­
cally brakes the vehicle and thereby keeps
speed constant when diffe rent wheel speeds
a re detected when descending a hill
c::> page 226. Your Audi also has permanent
a ll-wheel drive in addition.
H owever, your Aud i is not a pure off road vehi­
cle .
It was not built for d riving unde r extreme
conditions, e.g. fo r trips that are in the nature
of an expedition.
Dri ve only on road s and offroad section s
which mat ch the de sig n of your vehi cle and
y our a biliti es as a driver. Ne ver t ake ris k s!
Before driving offroad
- Check the eng ine oil level, tire pressure,
coolant level , and the fluid level in the w ind­
shield washe r reservo ir.
- Stow luggage items and other objects in the
luggage compartment, and secure them
against s lid ing aro und .
After driving offro ad
- After trips offroad, remove any twigs and
other foreign objects from the grill, the un­derbody and the wheels. Pay spec ia l atten­
t ion to fore ign objects (stones) which have
become lodged in the tire tread.
- Clean the body and the veh icle unders ide,
and inspec t the veh icle for poss ible damage.
- Clean dirty w indows , headlamp lenses , rear
l ights, and license plates .
- Perform a brake check (part icularly after
t ravel ling through water) .
A WARNING
-Drive especially attentively and plan
ahead in d iff icu lt road conditions and
when offroad. Excessive speed o r inco r­
rect maneuvers can cause injuries and
damage to the vehicle.
-
- Always adapt your speed and driving
style to road, offroad, t raff ic, and weath­
er cond itions. Drive especially slowly off­
road when you r view is res tricted.
- Please be awa re that in ESC off road
mode, particularly on a smoo th and s lip­
pery road, the wheels may have an in­
creased tendency to spin and the vehicle may break away -danger of skidding!
- Stability is limited in the ESC off road
mode .
@) For the sake of the environment
Avoid damage to the environment and re­
spect nature .

258 Fuel supply and filling your fuel tank
Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa­
tion, which may clog the fuel filter or tank fil­
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fue l filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No. 2 down to -10° F (-24° C).
If you expect temperatures below
5° F
(-15° C)
ask your fuel dealer whether their
Diese l fuel No.
2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
Diesel fuel has already thickened to the extent
that the engine will not start, warm the vehi­
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter. It is also norma l when whitish-blue
smoke comes out of the tailpipe after starting
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine idle unnecessari ­
ly after a cold start. Driving off slowly will
shorten the warm-up period.
A WARNING
- Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in ser ious engine damage and per­
sonal injur y.
- Never use fuel line anti-freeze offered for
gasoline engines.
(D Note
- Your Diesel engine has been specifically designed to operate only on Ultra Low
Sulfur Diesel fuel. Therefore, never use
home heating oil or regular gasoline. The
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
cause expensive engine repairs and will
also adversely affect your New Vehicle
Limited Warranty.
- If Diesel fuel sho uld get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por­
tion with soap and warm water. Do not allow D iesel fuel to remain on connect­
ing hoses . They may develop leaks and
cause serious damage.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system shou ld fail, you
can still open the flap manua lly -for detailed
instructions see ¢
page 261.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢page 322 .
The label on the inside of the fuel filler flap
te lls you the correct fuel for your vehicle. For
more information about fuel specifications,
see ¢
page 256.
Your vehicle fuel tank has an on-board refuel­
ling vapo r recovery system. This feature helps
to prevent fue l vapors from escaping from the
tank and polluting the environment while you refuel your vehicle. In order to fi ll the tank
proper ly while protecting the environment,
please fo llow this refueling procedure careful­
ly.
A WARNING
-Under normal operating conditions, never
carry addit ional fuel conta iners in your car .
Gas canisters and other conta iners used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision.
If you must
transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al ­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the ..,.

-Apply the parking brake.
- Move selector lever to "P" (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wa it until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances . This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
Checking and filling 265
- First, fully apply the parking brake,
move selector lever to "P" (Park) .
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­
ing hot parts . Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~&. .
