-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 00 \.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 215. 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.
.,.
65

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

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 130, fig. 140 . 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 00 \.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 215.
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
81

Wheels
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially
loaded ¢ table
on page 217 .
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 . 190 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 224 or ¢ page 226.
~check the pressure in the emer­
gency tire*/spare tire*. Always
maintain the maximum temper­
ature that is specified for the
tire.
216
& 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 218,
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.

a co .... N
" N .... 0 00 \.J ' @ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted .
Snow chains
Snow chains not only improve the driving in win­
ter road conditions, but also the braking .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive*.
.,. Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer .
.,. Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­ i zed Audi Service Facility to see if you may use
snow chains.
You must remove the snow chains on roads with­
out snow. Otherwise, you could impair driving
ability and damage the tires.
A WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci­
dent.
@ Note
- Snow chains can damage the rims/wheel
covers* if the chains come into direct con­
tact with them . Remove the wheel covers*
first . Use coated snow chains.
Wheels
- Using snow chains that add more than 0.4
inch (10.5 mm) of height can severely dam­
age the wheel housings and other vehicle
components.
- Do not install and use snow chains if there is
a malfunction in the air suspension*, be­
cause the vehicle height will be very low. If
you drive with snow chains anyway, the
wheel housings and other vehicle compo­
nents can be severely damaged .
(D Tips
When using snow chains, it may be useful to
switch on sport mode
c> page 121.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi­
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure
c>page 215.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand­
ard tires.
