-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 driving through salt water, because
this can cause corrosion.
Economical and environmentally-friendly
driving
The amount of fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style. With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­
proximately 10-15%. The following tips will help
you conserve the environment and your money at the same time.
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not
need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a
gear
engaged, for example, when you notice that the
next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (fuel shut-off during decelera­
tion) .
Shift efficiently
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fuel unnecessari­
ly .
Press down on the accelerator pedal slowly and
avoid "kick-down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
The Start/Stop system* helps to reduce the idling
time automatically. In vehicles without the Start/
8 Stop system*, it is efficient to switch the engine 0 \.J ' Driving
off when stopped at railroad crossings and long
red lights. Stopping the engine for 30-40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the engine.
It takes a very long time in idle to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm-up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while doing this .
Have maintenance performed regularly
By having maintenance performed regularly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The maintenance condition of your vehicle not only
affects traffic safety and long-term value but al ­
so impacts
fuel consumption . A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Avoid short trips
The engine and emissions control system must
reach their optimal operating temperature to ef­
fectively reduce consumption and emissions .
A cold engine uses a disproportionately high amount of fuel. The engine reaches operating
temperature and consumption normalizes only
after approximately
2 .5 miles (4 km) .
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct pressure
Q page 211. The
fuel consumption can increase by S% if the pres­
sure is only 0.5 bar too low . Due to the increased
rolling resistance, low tire pressures will also
lead to greater tire
wear and will affect driving
behavior.
Do not drive on
winter tires year -round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every pound of extra weight increases fuel
consumption, a quick inspection of the luggage
compartment may be worth it to avoid unneces -
sary weight.
.,.

Driving
When not being used, a roof rack should be re­moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62- 7 5 mph
(100-120 km/h) .
Save energy
The engine drives the generator, which generates
electricity ; the fuel consumption also increases
with the demand for electricity. Therefore, switch electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
@ Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
ind icate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper-
ty.
@ Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let. Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­ proved by the manufacturer .
- Do not alter or remove any device , such as
heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other important vehicle components .
@ 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 depending upon vehicle
66
load and speed, road and weather conditions ,
trip length, etc.
Steering
Manual steering wheel position adjustment
Applies to: vehicles with manual steering wheel adjustment
The steering wheel posi tion is adjustable up and
down and forward and back .

til it is secure.
A WARNING
Improper use of steering wheel adjustment
and improper seating position can cause seri­
ous personal injury.
-Adjust the steering wheel column only when
the vehicle is not moving to prevent loss of
vehicle control.
-Adjust the driver's seat or steering wheel so
that there is a minimum of 10 in (25 cm)
between your chest and the steering wheel
~page 126, fig. 138. If you cannot main­
tain this minimum distance, the airbag sys­
tem cannot protect you properly .
- If physical limitations prevent you from sit­
ting 10 in (25 cm) or more from the steer­
ing wheel, check with your authorized Audi
dealer to see if adaptive equipment is avail-
able.

" N .... 0 0 \.J - Trailer towing Driving with a trailer
General information
Your veh icle is primar ily intended for transport­
ing people and luggage. However, if you dr ive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg­
u lations.
Driving with a trailer affects the vehicle 's fuel
consumption, performance and wear. It also re­
quires highe r concentration from the driver.
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removab le ball
hitch mount and ball hitch. The trailer hitch must
be perm itted for the vehicle, the trailer and the
permitted total weight of the trailer being
pu lled. Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely
mounted. A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If the tra iler has its own brake system, then fol­
l ow the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Trailer towing
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The coo ling sys­
tem must be designed for additiona l load and
contain enough coo lant
i::> @ .
@ Note
Longer inclines cannot be driven without a
suitab le cooling system, especia lly if t he out­
side temperatures are high . otherwise, this
increases the risk of engine damage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
Your vehicle can only be operated with class 1 or
class 2 trailers.
Load distribution
Poor cargo load and distribut ion can negatively
impact vehicle handling.
- Store objects preferably in the vehicle luggage
compartment . The vehicle should always carry
the heaviest poss ible load and the trailer
should have the lightest possible load.
- Distribute the load in the trailer so that the
heavy objects are as close to the axle as poss i­
b le.
- Secure objects from sl iding out of place .
- Ut ilize the maximum permitted tongue weight
if possible .
Tires
Set the tire pressure on your vehicle for a "full
load"; see the tire pressure sticker
c::>page 211.
If necessary, also adjust the tire pressure on the
trailer according to the manufacturer's recom­ mendat ion .
Winter tires should be mounted on the vehicle and on the trailer during winter temperatures.
Outside mirrors
If you cannot see the tra ffic behind the trailer
with the standard exterior mirrors, then you

Checking the engine oil level
The engine oil level can be checked in the Info ­
tainment system
Observe the safety precautions ¢ A in Working
in the engine compartment on page 189.
~ Park your vehicle on a level surface.
~ Shut the engine off when it is warm .
~ Switch only the ignition back on.
~ Wait approx imately two minutes.
~ Select : the ICARI function button > (C ar)* Sys ­
tem s

~ Read the o il level in the display. Add eng ine oil
i f t he ba r in the oil leve l ind icator is just before
"min" ¢ page 194.
(UJ) Note
The engine oil leve l mus t not be unde r the
"min" mark ing, as this will increase the risk of
engine damage.
(D Tips
The o il level indica tor in the disp lay is on ly an
informationa l display. If the o il level is too
low, a minimum oi l warning appears in the in ­
strument cluster. Add oil and close the hood.
The current oil level is d isplayed in the Info­
tainment system the next t ime the ignition is
sw itched on.
(D Tips
The engine oil consumption may be up to
0.5 quart/600 m iles (0.S liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumpt ion may be h igher during the
first 3,000 miles (5,000 km). Because of this,
the eng ine oil level m ust be checked regu lar­
ly. I t is best to chec k each t ime yo u refuel
your veh icle and befo re long d rives .
Ch eck ing and F illing
-In order to prov ide effective lubrication and
cooling of interna l engine components, a ll
internal comb ustion engines consume acer ­
tain amount of oil. Oi l consumption var ies
from engine to engine and may change sig­
nificantly over the life of the engine . Typi­
cally, eng ines with a specified break-in peri­
od consume mo re o il du ring the break-in pe­
r iod than they consume afte r oil cons ump­
t ion has s tabilized.
-Under norma l co ndit io ns, the rate of oil
cons umption depe nds on the q ual ity and
vis cos ity of the oil , the R PM (revo lutions per
m inute) a t which the engine is operated, the
ambient temperature and road conditions .
Further factors are the amount of oi l di lu­
tion from water condensat ion or fue l resi­
due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage builds
up, the oil consumption may increase over
t ime until replacement of worn components
may become necessa ry.
-With all these var iables com ing into play,
no sta ndard rate of o il consumption can be
established o r specified. There is no a lter na­
ti ve to c hec king the oil leve l reg ularly and
frequently.
-If you have the impress ion your e ngine co n­
sumes excessive amo unts o f oil, we recom ­
mend that you consult an author ized Audi
dea ler to have the cause of your concern
properly diagnosed . Keep in mind that t he
acc urate measurement of o il cons umption
requires great care and may take some
time . An authorized Aud i dealer has instruc­
tions about how to measu re o il consump­
tion accurate ly.

Wheels
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially
loaded ¢ table
on page 213 .
If driving the vehi­
cle when fully loaded, you must
increase the tire pressure to the
maximum specified
pressure ¢.&. -
Checking/correcting tire
pressure
~check the tire pressure at least
once per month and also check it
before every long drive .
~Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
~check the label¢ fig . 188 for
the correct tire pressure based
on vehicle load.
~correct the tire pressure if nec­
essary .
~store the new tire pressure in
the Infotainment system
¢ page 220.
~check the pressure in the emer­
gency tire*/spare tire*. Always
maintain the maximum temper­
ature that is specified for the
tire.
212
& WARNING
Always adapt the tire pressure
to your driving style and vehicle
load .
-Overloading can lead to loss of
vehicle control and increase
the risk of an accident. Read and follow the important safe­
ty precautions
in¢ page 214,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
{tfj) Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
