@ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions, do not let your
vehicle stand and warm up. Be ready to
drive off immediately after start ing your
veh icle. Mainta in moderate speed until the
engine is completely warm . Remember,
the engine performs best at operating
temperature .
Stopping the engine

¢page 89, fig. 102.
_& WARNING
-Never turn off the engine unti l the vehi­
cle has come to a complete stop.
- The brake booster and servotronic on ly
work when the engine is running . With
the ignition turned off, you have to apply
more force when steering or braking.
Since you cannot steer and stop normal­ ly, this can lead to accidents and serious
injuries.
- The rad iator fan can continue to run for
up to 10 minutes even after you have
tu rned off the eng ine and removed the
ignition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build-up in the engine compartment.
(D Note
Do not stop the engine immediate ly after
hard or extended dr iving. Keep the engine
running for approximately two minutes to
prevent excessive heat build-up .

S tronic transmission
· Introduction
Applies to vehicles: with S tronic®
Your vehicle is equipped with a S tronic trans­
mission, also called a double-clutch system/
transmission .
Power is transferred between the engine and
the transmission by means of two independ­ ent clutches. They replace the torque convert­
er of conventiona l automatic transmissions
and allow the vehicle to accelerate without a
not iceable break in the power flow.
With the aid of
tiptronic, the gears can op­
t ionally be shifted
manually ~ page 100.

A WARNING
- Never p lace the selector lever in the R or
P posit ion while the veh icle is moving -
risk of an accident!
- With the engine running, it is necessary
to hold the vehicle with the foot brake in all se lector lever positions (except P and
N), because even at idle speed the trans­
fe r of power is never completely inter­
rupted -the vehicle "creeps". If the vehi­
cle is stationary and the transm ission is
engaged, the engine should never be
speeded up unintentionally (e .g. manual­
ly from under the hood). Otherwise the
veh icle w ill immediately start to move -
sometimes even if the park ing brake is
firmly applied -risk of an accident!
- Before you or other persons open the
hood and work on a running engine, the
selecto r lever must be moved to P and
the park ing brake applied f irmly - risk of
an accident! Follow the warning sticke rs
