cern.
.&_ WARNING
-~ ·
-Never allow the engine to run in confined
spaces - danger of asphyxiation.
- Never turn off the engine until the vehicle
has come to a complete stop.
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed . This can lead to serious injury.
- Never leave children or persons requiring as­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing people from escaping
from the vehicle on the ir own in the event of
an emergency. Depending on the time of
year, people inside the vehicle can be ex­
posed to very high or very low tempera­
tures.
CD Note
- Avo id high engine rpm, full throttle and
heavy eng ine loads until the engine has
reached operating temperature -otherwise
you risk engine damage.
@ For the sake of the environment
Do not let the engine run wh ile parked to
warm up. Begin driving immediately. This re­
duces unnecessary emissions .
@ Tips
-After starting a cold engine, there may be a

Starting and automatically releasing the
park ing brake
.. When you sta rt to drive as usual, the parking
bra ke is automatically released and yo ur vehicle
beg ins to move.
When stop ping at a traffic signal or stopping in
c ity t raffic on vehicles with an a utomat ic t rans ­
mission, the parking brake can be app lied. The
vehicle does not have to be he ld with the foot­
brake. The pa rking brake eliminates the tendency
to c reep with a d rive ra nge engaged. As soon as
yo u drive off as usua l, the park ing b rake is re­
l eased a utomat ica lly and the vehi cle starts to
m ove .
Starting on slopes
When sta rting on inclines, the starting assist pre ­
ven ts the vehicle from unintentionally ro lling
bac k. The braking force of the parking b rake is
n ot released until suff icient dr iving force has
been built up at the wheels.
(D Tips
For safety reasons, the pa rking bra ke is re­
l eased a utoma tically on ly w hen t he d river's
s a fety be lt is en gaged in t he b uckle.
Starting off with a trailer
To prevent rolling back unin tentionally on an in­
cline, do the f ollowing:
.. Keep the sw itch @¢ page 77, fig . 81 pulled
and dep ress the accelera to r. T he pa rking brake
s t ays app lied and p revents the veh icle from
roll ing ba ckw ard .
.. Yo u can re lease the swi tch @ once you are s ure
that you are deve loping enough d riving force at
the whee ls by depressing the accelerato r.
Depend ing on the weight of the rig (vehi cle an d
t ra ile r) and the seve rity of the incline, yo u may
r o ll backwards as yo u start. You can p revent roll­
i ng backwards by holding the parking brake
switch @pulled o ut and acce lerating -just as
you would when starting on a hill wi th a conven­
tiona l hand b rake .

S tronic, tiptronic
Introduction
Applies to vehicles: with S tronic/tiptronic
The automatic transmission is controlled elec­
tron ically. The transmission upshifts or down­
shifts automatica lly depending on which drive
program is selected .
When a
moderate driving style is used, the
transmission selects the most economical driving
mode. It will then change up early and delay the
downshifts to give better fuel economy.
The transmission switches to a sporty mode after
a kick-down or when the driver uses a
sporty driv­
ing style
characterized by quick acce lerator pedal
movements, heavy acce leration, frequent
changes in speed and traveling at the maximum
speed .
If desired, the driver can a lso select the gears
manually (tiptronic mode) c::> page 86.
Various automatic transmissions may be instal­
l ed, depending on the model :
S tronic transmission
The S tronic is a dual-clutch transmission . Power
i s transferred using two clutches that work inde­
pendently from one another . They replace the
torque converter used in conventio nal automatic
transmissions and allow the vehicle to accelerate
without a noticeable interruption in traction .
tiptronic transmission
In the tiptronic t ransm ission, power is transfer­
red by a torque converter.
