A WARNING
Electrolyte fluid can leak from automatic dim­
m ing mirrors if the glass is broken. Electro­
lyte fluid can irritate skin, eyes and airways.
- Repeated or long-term exposure to electro-
lyte fluid can lead to irritation of the a ir ­
ways, especially in people with asthma or
other resp irato ry conditions. Take deep
breaths immed iate ly after leaving the vehi­
cle or, if this is not possible, open all of the
doors and windows as wide as possible .
-If electrolyte f lu id ente rs the eyes, flush
them thoroughly with a large amount of
clean water for at least 15 minutes and then
seek medical attention.
- If electrolyte f luid comes into contact with
the skin, flush the affected area with clean
water for at least 15 minutes and then clean
with soap and water and seek medical at­
tention. Clean affected clothing and shoes
thoroughly before wearing again .
- If the fluid was swallowed and the person is conscious, flush the mouth with water for at
least 15 minutes. Do not induce vomiting
unless this is recommended by med ical pro-
42
fessionals . Seek medical attention immedi­
ately .
(D Note
If the glass on an automatic dimming mirror
breaks, electro lyte can leak out . This liquid
damages plastic surfaces. Remove the liquid

Avoid full acceler ation
You sho uld rare ly t rave l a t t he maxim um vehicle
speed . High speeds cause a disproportionately
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
It pays off to stop the eng ine, for example when
at ra ilroad crossings or traffi c lights w ith longer
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.
I t takes a very long time in idle to wa rm the en­
gine up to operating tempera ture . Wea r and
emissions are especially high in the warm -up
p hase . Therefore, you should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Hav e ma intenanc e performed r egularly
By having maintenance performed regu lar ly on
your vehicle, you can he lp to reduce fuel con ­
sumption before yo u even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term va lue but al­
so impacts
fu el con sumpt ion .
A poorly maintained engine can lead to fuel con ­
sumpt ion that is 10% higher than norma l.
A lso check the
o il l evel when refueling . The oil
consumpt ion
depends large ly on the engine load
and speed. It is normal for the oil consumption
of a new eng ine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can only be properly judged after
approx imately 3,000 m i (S,000 km) have been
driven.
Avoid short trips
The engine and exhaust clean ing system must
reach their opt imal
op erating temp eratur e to ef­
fective ly reduce consumpt ion and emiss ions.
A co ld engine uses a disproportionately h igh
amount of fuel. The eng ine reaches operating
temperature and consumpt ion normalizes only
afte r approx imately
2.5 miles (4 km) .
Driving
@ Note
Do not leave engine idling unattended after
start ing. If warning lights sho uld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could resu lt in overheating or
other damage to the veh icle o r other proper­
ty.
@ Note
- Have your ve hicle ma intained properly and
in accordance w ith the service recommenda­
tions i n your Warranty
& Main tenance book­
let. La ck of prope r mai nte nan ce as we ll as
imp rope r use of t he ve hicle will impa ir the
function of the em iss ion cont ro l system and
co uld lead to damage .
- Do not alte r or remove any compone nt o f
t he Emission Contro l System unless ap ­
proved by the man ufacturer .
- Do not alte r or remove any dev ice, s uch as
heat shields, switc hes, ignition wires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
impo rtant ve hicle components.
(D Tips
The cons umption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and T ransport Canada may not co rre­
spond to your actual consumption on the r oad, wh ich w ill vary depending upon veh icle
l oad and speed, road and weather cond itions,

-Never turn off the engine before the vehicle
has come to a complete stop.
- The brake booster and power steering only
work when the engine is running. If the en­ gine is off, you have to use more force when
steering or braking. Because you cannot
steer and brake as you usually would, this
could lead to accidents and serious injuries.
@ Note
Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately . This re­
duces unnecessary emissions.
(D Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Stopping the engine
.,. Bring the vehicle to a full stop.
.,. Move the selector lever into the P position .
... Press the I START ENGINE STOPI button.
Emergency off function*
If it is absolutely necessary, the engine can also
be turned off while driving at speeds starting at
4 mph (7 km/h). To switch the engine off, press
the
I START ENGINE STOPI button twice in a row
br iefly or press and hold for longer than two sec­
onds.
A WARNING
- Never turn off the engine before the vehicle has come to a complete stop.
Driving
-Please note that the brake booster and pow­
er steering only work when the engine is
running. When the engine off, you must use
more force to steer or brake the vehicle. Be­
cause the usual steering and braking capa­
bility is not available, the risk of accidents or
. . . . mJunes increases.
-For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll.
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes
-even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the result of heat buildup or if the engine is al­
ready warm and the engine compartment is
also heated by the sun's rays.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the
engine is
switched off and there is a risk of damaging
the engine . For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
(D Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­ matically or it may continue to run (even if
the ignition is switched off) for the following
reasons :
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­
light.

Automatic transmission
Introduction
Your vehicle is equipped with an electronically­
controlled DSG transmiss ion called S tronic. Two
independent clutches transfer the power be­
tween the engine and transmission . It allows the
vehicle to accelerate without a noticeab le inter­
ruption in traction.
The transmission upshifts or downsh ifts auto­
mat ica lly. The driving style continuously influen­
ces the selection of the driving program.
When a
mod erat e d rivin g sty le is used, the
transmission selects the most economical d riving
mode. The transmiss ion upsh ifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
The transm ission switches to a spo rty mode after
a kick-down or when the driver uses a
s po rt y
d riv ing sty le
characterized by quick accelerator
pedal movements, heavy acce leration, frequent
changes in speed and traveling at the maximum
speed.
If desired, the driver can also select the gears
manually ( tipt roni c mod e).
