Automatic transmission multitronic, S tronic,
tiptronic
Introduction
Applies to: vehicle s with multitronic/S tronic/tiptronic
The automatic transmission is cont rolled e lec­
tronica lly. The transmission upshifts or down­
shifts automatically depending on which drive program is selected.
When a
moderate drivi ng 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 transm ission switches to a sporty mode afte r
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 { tip tron ic mode) 9 page 81.
Various automatic transmissions may be instal­
led, depending on the model :
multitronic transmission
The multitronic transmission is a cont inuous ly
va riable t ransmiss ion. Power is transferred using
a mu ltidisk clutch. In contrast to conventiona l
automatic transmissions using shifting opera­
tions, the transmission ratio in the continuous ly
variable transmiss ion is changed continuously.
This optimizes the comfort level and conserves
fuel.
S tr onic transmi ssion
The S tronic is a dua l-clutch transmiss ion . Power
is transferred using two clutches that work inde­
pendently from one another. They replace the
torque converter used in conventional automatic
transmissions and allow the vehicle to accelerate
without a noticeable interruption in tract ion.

ing gear
The Automatic Shift Lock only functions whe n the
vehicle is stat ionary or at speeds be low 1 mph
(2 km/h) .

At speeds above about 1 mph (2 km/h) the Auto­
matic Shift Lock is automatically deactivated in
the N position.
A time delay element prevents the selector lever
from locking when it is moved through the N po­
sition (going from R to D/S). The locking e lement
will lock the se lector lever if the lever is left in N
(Neutral) for more than approx imately 2 sec­
onds, without the brake pedal being pressed.

Automatic transmission
This prevents too much stress from being placed
on the locking mechanism.
Vehicles with multitronic transmission: Your ve­ hicle is equipped with
hill hold assist allowing
you to start while on an incline. The system is ac­
tivated when the brake pedal is pressed down
and held
for a few seconds. The brake pressure
will hold for
a moment after the brake pedal
loosens to prevent the vehicle from rolling back­
wards while starting up.
A WARNING
- The vehicle can also roll when the engine is
stopped.
- Unintended vehicle movement can cause se­ rious injury.
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running, ac­ tivate the parking brake and move the selec­
tor lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must
keep your foot on the brake when the en­
gine is running and the selector lever is in 0/
Sor R or "tiptronic" mode is selected.
- Do not press the accelerator pedal when changing the selector lever position while
the vehicle is stationary and the engine is
running.
- Never shift into R or P while driving.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it in
place with the brake pedal or parking brake.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati-
84
cally when it becomes too hot from the
overload. An indicator lamo
[O ] illuminates
and a driver message appears
c::;, page 86
when the clutch is overloaded.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure these­
lector lever has securely engaged and is
locked in P with the parking brake set
¢page 193. Otherwise, any increase in en­
gine speed may
set the vehicle in motion,
even with the parking brake applied.
(D Note
- S tronic- and tiptronic transmission: When
stopping on an incline, do not try to hold
the vehicle in place by pressing the accelera­
tor pedal while a driving gear is selected.
This can cause the transmission to overheat
and can damage it. Activate the parking
brake or press the brake pedal to prevent
the vehicle from rolling.
- S tronic- and tiptronic transmission: Allow­
ing th@ vehicle to roll when th@ engine is
stopped and the selector lever is in N will
damage the transmission because it is not
lubricated under those circumstances.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle.
· Hill descent control
App lies to: vehicles with mult itron ic/S tron ic/t iptronic
The hill descent control system assists the driver
when driving down declines .
Hill descent control is activated when the selec­
tor lever is in D/S and you press the brake pedal.
The transmission automatically selects a gear
that is suitable for the incline. Hill descent con­
trol tries to maintain the speed achieved at the
time of braking, within physical and technical
limitations. It may still be necessary to adjust the
speed with the brakes. ..,..
