2013 AUDI Q7 catalytic converter

12 Instruments and warning/indicator lights
Speedometer with odometer
The speedometer shows you the vehicle
speed, and the odometer shows you how many miles (kilometers) you have driven.
Fig. 5 Instrument cluster Odometer and reset button
The odometer and trip odometer are located
inside the speedometer.
- USA mode ls - Miles
- Canada models -Kilometers
You can switch the display from miles to kilo­ meters and vice versa via the MMI. You can
find out more in the MMI manual.
Lower odometer
The lower odometer shows the total number
of mi les (kilometers) driven.
Upper odometer (trip odometer)
The upper odometer shows the tota l number
of mi les (kilometers) driven since you last re­
set the odometer to zero. You can use this od­
ometer when you want to keep track of how many miles (k ilometers) you have driven for a
single trip or errand. The last digit indicates
1/10 of a mile (100 meters).
You can reset the trip odometer to zero by
pressing the Reset button

thorized Audi dealer to have the problem cor­
rected.
(D Tips
- When you open t he driver door, the time,
date and odometer are disp layed for an

strument cluster d isplay as well as the mes ­
sage
Please refuel. This message is meant to
remind you to
refuel.
The total tank capacity of your vehicle is listed
in
.:> page 322 .
@ Note
Never run the tank completely dry. An ir­
regular supply of fuel can cause engine
misfiring and fuel could enter the exhaust
system. The catalytic converter could then
overheat and be damaged.

Fig. 6 CHECK button in th e ins trument cluster
The !CHECK I button performs the following
functions:

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
II symbo l for the diesel
particu late filter ill uminates ¢
page 3 7.
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. ..,. •

Selective catalytic
reduction
General information
App lies to vehicles : with diesel engine
On vehicles w ith select ive catalytic reduction,
an urea solut ion (Ad Blue ®) is injected into the
exhaust system befo re a nitrogen oxide cata­
lytic converter to reduce nitrogen em iss ions.
The AdBlue is stored in a separate tank in the
veh icle. The AdBlue usage accounts for ap­
p rox imately 0.5% to 1.2% of the diese l fuel
that is used. The Ad Blue tank capaci ty is ap ­
pr ox ima tely 6 gallons (23 liters).
You must refill the Ad Blue or have it refilled
by your authorized A udi dealer or qualified
wo rkshop as soon as the Ad Bl ue refill mes-
Fu el suppl y and filli ng your fuel t ank 261
sage appears in the instrument cluster
¢ page 262.
A WARNING
Failure to heed AdBlue refill info rmation in
the instrument cluster can prevent the ve­ hi cle from be ing started and dr iven. If the
vehicle cannot be driven and a n emerge ncy
a rises, pe rsonal injury can occur.
- Always have the AdBlue tank refilled well
befo re the tank runs dry .
(D Tips
- The instrument cluster d isp lay ind icates
the distance remain ing that can be driv­
en ¢
page 261. If the Ad B lue tank is
completely empty, the engine will not
start again afte r the ignit ion is switched
off.
- Ad Blue is req uired by law to operate th is
veh icl e.
