-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 '<t
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.

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

Driving safety
Basics
Safe driving habits
Please remember -safety first!
The individua l safety features of your vehicle can
work together as a system to help protect you
and your passengers in a wide range of accidents.
These features cannot work as a system if they
are not always correctly adjusted and correctly
used .
This chapter contains important informat ion,
tips, instruct ions and warn ings that you need to
read and observe for your own safety, the safety
of your passengers and others . We have summar­
i zed here what you need to know about safety
be lts, a irbags, child restra ints as well as child
safety. Yo ur safety is for us priority number 1. Al­
ways observe the information and warnings in
this section - for your own safety as well as that
of your passengers.
The informa tion in t his sect ion app lies to all
model versions of your vehicle. Some of the fea ­
tures described in this sections may be standard
eq uipment on some models, or may be optional
equ ipment on others. If you are not sure, ask
your author ized Audi dealer.

Important things to do before driving
Safety is everybody 's job ! Vehicle and occupant
safety always depends on the informed and care­
ful driver .
For your safety and the safety of your passen­
gers,
befor e dri ving alw ays:
.. Make sure that a ll lights and signals are operat­
ing correctly.
.. Make sure tha t the tire pressure is correct .
.. Make sure that all windows are clean and afford
good vis ibility to the outs ide .
.. Secure all luggage and othe r items ca refully
¢ page 54, ¢page 53 .
.. Make sure that not hing c an interfere wi th the
peda ls .
.. Adjust front seat, head restraint and mirrors
correct ly for your height.
.. Instruct passengers to adjust the head re­
straints according to their height.
.. Make sure to use the rig ht child restra int cor­
rectly to protect children
¢ page 170, Child
safety .
.. Sit properly in your seat and make sure t hat
your passengers do the
same ¢ page 47, Seats
and storage.
.. Fasten your safety belt and wear it properly . Al ­
so instruct your passengers to fasten their safe­
ty belts
properly ¢ page 138 .
What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle , the driver as well as the driver 's abili­
ty to concentrate on the road without being dis­
tracted.
The driver is responsib le for the safety of the ve ­
hicle and a ll of its occupants. If your ability to
drive is impa ired, safety risks for everybody in the
vehicle increase and you a lso become a hazard to
everyone else on the road
¢ &_ . Therefore:
.. Do not let yourse lf be distracted by passengers
or by using a cellular telephone .
.. NEVER drive when your driving abi lity is im­
pa ired (by med ications, alcohol, drugs, etc .) .
.. Observe all traffic laws, rules of the road and
speed lim its and plain common sense .

~ Make sure that the rear seatback is securely
latched in place.
A WARNING
Improperly stored luggage or other items can
fly through the vehicle causing serious per ­
sonal injury in the event of hard b raking or an
accident . To help reduce the risk of serious
personal in jury:
- Always put objects, fo r example, luggage o r
other heavy items in the luggage compart­
ment.
- Always sec ure objects in the luggage com­
partmen t using the tie-down hooks an d
s u itable straps.
A WARNING
Heavy loads wi ll influence the way yo ur vehi­
cle handles. To he lp reduce the ris k of a loss
of contro l leading to serio us pe rsonal injury:
- Always keep in mind when transporting
heavy objects, that a change in the center of
gravity can also cause changes in vehicle
handling:
- Always d istribute the load as evenly as
possible.
- Place heavy objects as far forward in the
luggage compartment as poss ible .
- Never exceed the Gross Axle Weight Rating or the Gross Vehicle Weight Rat ing specified
on the safety compliance sticker on the driv­
er's side B-p illar. Exceeding permissible
we ight s tanda rds can cause the vehicle to
slide and handle differently .
- Please obse rve information on safe driving
~page 1 2 9.
A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed wh ile driving.
- Never transport objects larger than those
fitt ing completely into the luggage area be­
cause the rear lid can not be fully closed.
-
Dri ving saf ety
- If you absolutely m ust dr ive with the rear lid
open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the power roof*,
- Open all a ir outlets in the instrument pan-
el,
- Switch
off the air rec irculat ion,
- Set the fresh air fan to the highest speed.
A WARNING
=
A lways make su re that the doo rs, all win-
dows, the powe r roof* and the rea r lid are se­
curely closed and locked to reduce the r isk of
i njury when the veh icle is not being used .
- After closing the rear lid , always make sure
that it is properly closed and locked .
- Never leave your veh icle unattended espe­
cially with the rear lid left open . A child
could crawl in to the vehicle th rough the lug­
gage compartment and close the rea r lid be­
coming trapped and unab le to get o ut. Be­
ing trapped in a vehicle c an le ad to ser ious
pe rsonal injury.
- Never let children play in o r around the vehi­
cle .
- Never let passengers ride in the luggage
compa rtment. Vehicle occupants mus t al­
ways be p roperly restrained in one of the ve­
h icle's seat ing pos itions.
(D Tips
- Air circulation helps to reduce w indow fog­
ging. Stale air esc apes to the outs ide
t hrough vents in the tr im panel. Be sure to
keep these slots free and open.
- The tire p ressure m ust co rres pond to the
load. The t ire pressure is shown on the tire
pressure label. The t ire pressure label is lo ­
cated on the dr iver's side B-pillar . The tire
pressure label lists the recommended cold
tire inflation pressures fo r the veh icle at its
maximum capac ity weight and the tires that
we re on your vehicle at the time it was man ­
ufac tured . For recommended t ire pressures
