2017 AUDI Q5 check engine

Driving and th e en vironm ent
consumption by 10-15 percent. This section will
give you some tips on how you can help the envi­
ronment and your pocketbook.
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depend ing upon vehicle
load and speed, road and weather conditions,
trip length, etc .
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating .
"'Avo id unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
erate less . Let the vehicle coast whenever possi­
ble -for example when you see that the next traf­
fic light is red .
Avoid full throttle
Driving a t moderate speeds saves fuel and im­
proves your mileage .
"'Try and keep well below your car 's maximum
speed .
Accelerating gent ly reduces fuel consumption,
engine wear, and does not disturb the environ­
ment.
Fue l cons umption, exhaust emissions and engine
noise increase d isproportionately at high speeds .
If you drive at approximately three q uarters of
top speed, fuel consumpt ion w ill be reduced by
one half. Never drive faster than the posted
speed limit and weather conditions permit.

· Reducing unnecessary idling
E ven when your car is just idling it burns up fuel .
"'Shut the engine off when you are not driving
the vehicle.
"' Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automatically reduced for
vehicles with the Start-Stop-System*. It is effi­ c ient to sw itch off the engine in vehicles without
the Start-Stop-System* when stopped at ra ilroad
cross ings and long red lights. Turning the engine
off fo r just 30-40 seconds saves more fuel than is
bur ned by s tarting the engine again .
It takes a long time for the engine to warm up
fully when it is runn ing at id le . However, wea r
and noxious emissions are especially high when
the engine is warming up . So yo u should dr ive
away as soon as you sta rt the eng ine and avo id
running at hig h rpms whi le the engine is st ill
warming up .
Q) Note
Do not leave eng ine idling una ttended after
starting. If warning lights shou ld come on to
indicate improper operation, they would go
unheeded. Extended idling also prod uces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty .
· Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
"' Have your vehicle serviced at regular interva ls.
By having your vehicle regular ly serv iced by an
authorized Audi dea le r helps to ensure that it
r uns prope rly and economically . The condition of
your vehicle not on ly affects its safety and ability
to hold its value, it also affects
fuel consump­
t ion .
Check your oil each time you fill your tank.

Driving tips
On poor rood and offrood, there is always only
one motto: Plan ahead and drive slowly!
Please observe the following when driving away
from paved roads:
~ Drive only on roads and offroad sections wh ich
match the design of your veh icle and your abili ­
ties as a driver. Never take risks!
~ Drive slowly and plan ahead!
~ Take into consideration the ground clearance
of your veh icle.
~ Activate the off road mode q page 186 as need­
ed .
~ Use the hill descent assist q page 188 when
driv ing down steep sections on h ills.
Unpaved road s and offroad
Drive s low ly on unfamiliar roads and unknown
offroad sections, and look out for unexpected ob­
stacles (e .g . potholes, rocks, tree stumps, etc .).
T o prevent the vehicle from bottoming and avoid
damage to the underbody, you should drive
stra ight across severe bumps in the ground with
only one side of the vehicle so that only two of
your wheels cross the bumps .
Drive briskly through sandy or marshy offroad
sections and do not stop, if at all possible.
Driving through water
Note the following to avoid vehicle damage when
driving through water, for example on flooded
roads:
- Th e wate r must not be any higher than the bot-
tom of the vehicle body.
- Do not drive faster than walking speed.
Driving on a slope
If you ever find yourself not able to climb a slope,
do not try to turn around, drive back down in
re­
verse.
Othe rw ise, you run the risk of tipping over.
Offroad driving
If the vehicle threatens to tip over when driving
across a slope, you must immediately steer
downhill in the direction of the slope.
Do not park your vehi cle on steep slopes or
grades .
T o reduce the risk of tipping over, drive on slopes
i n the direction of the downward slope (fall line) -
not crosswise .
& WARNING ~ -
After driving thro ugh water, mud, slush, etc.,
the brakes may be slow to take effect beca use
of wet brake rotors and pads. Dry the brakes
f ir st by braking carefu lly to restore the full
braking effect.
(D Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys ­
tem can be severely damaged by driving
through water .
- Always switch off the Start-Stop-System*
when driving through water
Q page 90.
(D Tips
-Check the depth of the water before driving
through it.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
-Avoid dr iv ing through salt water because it
can cause corros ion.

Fig. 188 Permi tted ba ll pos it io n of the trailer h itch
Trailer towing weights
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissible trailer weight is
4,400 lbs (2,000 kg) . The maximum permissible
unbraked trailer weight is 1,650 lbs (750 kg).
These specifications apply when driving on roads having an incline of less than 12%.
Permissible tongue load
For best vehicle handling under these changed
conditions, adjust the trailer load so that the
tongue load is at the maximum allowable or
slightly lower. You can get an approximation of
the tongue load with a bathroom scale or you can
measure the load at a trucking company or
weighing station.
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissible load on the ball
hitch may not exceed 440 lbs (200 kg) .
It is rec­
ommended to use the maximum permissible
load.
Trailer load distribution Be sure the load in the trailer is held securely in
place to prevent it from shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer ¢.&.
in Driving instructions on page 202.
Ball mount
The trailer hitch may only be used with suitable ball mount and ball¢
fig. 188 . Installation of
the hitch ball must be carried out in accordance
with the manufacturer's instructions .
Trailer towing
Engine cooling system
Towing a trailer makes the engine work harder. It
is important that the cooling system's perform­
ance is up to the additional load. Make sure that
the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the tire pressure listed under "Full
load" on the label¢
page 240. Inflate trailer
tires to trailer and tire manufacturers' specifica­
tions.
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle .
Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains should cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
· Driving instructions
Driving with a trailer always requires extra care
and consideration.
Weight distribution
Towing a loaded trailer with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced " rig is easier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keeping the trailer as light as possible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while observing tongue load require-
ments and vehicle loading considerations. .,.

Gasoline additives
Applies to: vehicles with gasoline engine
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine parts, such as fuel injectors and intake valves . Al ­
though most gasolin e brands include additives to
keep engine and fuel systems clean, they are not
equally effe ctive.
Audi recommends using TOP TIER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline , please go to the official website
(www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon depos its can rob your en­
gine of peak performance.
CD Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New Vehi­
cle Limited Warranty .
- Do not add aftermarket fuel additive prod­
ucts to your fuel tank.
Diesel fuel
Applies to: veh icles with diesel eng ine
Always use ULSD (Ultra Low Sulfur Diesel) No. 2.
The ULSD No . 2 meets the ASTM 0975.
Diesel fuel with concentrations of biodiesel high­
er than S % such as 811,820 or 8100 are strictly prohibited.
Service station fuel pumps are labeled with the
correct fuel information for easy recognition by
the user. If the diesel fuel pump is not labeled
ask the station operator what fuel is being dis­
pensed before filling up your vehicle .
ULSD No . 2 may not be available outside the USA
and Canada. Be sure to check before traveling to
other countries.
Fuel and Refueling
ULSD No. 2 can become thicker in very cold tem­
peratures, and this can impair the engine 's start­
ing and running. Depending on the season, gas
stations provide ULSD No.
2 that flows better in
cold temperatures so tha t you can continue oper­
ating your vehicle as usual.
CD Note
- Your vehicle's diesel engine was designed
soley for use with ULSD No.
2. Therefore,
never use gasoline, heating oil, other fuels
or flow improvers . These contain substances
that will severely damage the fuel system
and the engine. Such damage will not be
covered by your New Vehicle Limited War­
ranty.
- If you put any amount of incorrect fuel in
the fuel tank, do not start the engine under
any circumstances. Immediately contact the
nearest authorized Audi dealer or author­
ized Audi Service Facility for assistance.
These fuels contain substances that can se­
verely damage the fuel system and the en­ gine if the engine is started .
Refueling
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 should fail, you can
still open the flap manually -for detailed instruc­
tions see
¢ page 213.
You can find the fuel tank capacity of your vehicle
in
¢ page 273.
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
format ion about fuel specificat ions, see
¢ page 209.
Your vehicle fuel tank has an on-board refuelling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and polluting the environment while you refuel your
vehicle. In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully.
211

Fuel and R efue li ng
_& WARNING
Under normal operating conditions, never car ­
ry additional fuel containers in you r car. Gas
canisters and other containers used to trans­
port fuel can be dangerous . Such containers,
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 a lways observe local and
state laws regarding the use, transportation
and sto rage of such fue l conta iners. Make cer­
tain the container meets industry standards (ANSI/ASTM F852 -86) .
(D Note
Never drive you r vehicle unt il the fuel tank is
comp letely empty. The irregular supply of
fue l can cause m isfiring. Gasoline cou ld enter
the exhaust system and damage the catalytic
converter.
Refuelling

.. Check the label on the inside of the fuel filler
flap to determine if the vehicle must be fueled
w ith gasoline or diesel fuel.
Refuelling procedur e
.. Insert the fuel nozzle from the gasoline pump
into the fuel filler neck as far as it will go.
.. Select a medium refuelling rate so that the
nozzle switches off automatically when the
tank is full.
Putting th e fu el c ap b ack o n
.. After filling your tank, twist the fuel cap clock-
wise as far as it will go.
.. Close the fuel filler flap.
To avoid fuel spilling or evaporating from the fuel
tank always close fuel cap properly and com­
plete ly. An improperly closed fuel filler cap may
also cause the MIL lamp¢
page 23 to come on
(only vehicles with gasoline engine).
_& WARNING
Improper refueling or handling of fuel can
cause fire, explos ion and severe burns.
- Fuel is highly flammable and can cause se­
vere burns and other injuries.
-
- Fa ilure to shut the engine off while refuel­
ing and/or to insert the pump nozzle fully into the fue l filler neck could cause fuel to
spray out of fi ller neck or to overflow. Fue l
spray and ove rflowing f uel can ca use a fire .
- Never use a ce llular telephone while refuel­
ing. The electromagnetic radiation can
cause sparks t hat can ignite fuel vapors and
cause a fire.
- Never get back into your vehicle whi le refu­
eling. If in exceptional circumstances you
must get back in your vehicle wh ile refuel­
ing, make certain that you close the door
and touch metal to discharge static electric-
ity before touching t he f iller nozzle again. .,_
