Automatic Transmission
multitronic ®
Introduction
Appl ies to vehicles: with multitr oni c
Your veh icle is equipped with an electronically
controlled,
continuously variable transmis­
sion
(multitronic ®). In contrast to convention ­
al automatic transmi ssions using shifting op­
erations, the transmission ratio in the contin­
uously variab le transmission is changed con ­
tinuously. This optimizes the comfort level
and conserves fuel.
The gear ratio in the transmission is selected
(upshift and downshift) completely automati­
cally as a function of the defined driving pro­
grams.
If desired, the driver can also select the gears
manually (tiptronic mode).
Instead of the torque converter in convention­
al automatic transmissions, your multitronic ®
transmission uses a multidisk clutch for pow­
er transmission . Therefore, the "creep behav­
ior" of the veh icle dur ing idling when tempo­
rarily stopped in selecto r lever pos it ion 0/S or
R is less pronounced.

A WARNING
-- Unintended vehicle movement can cause
serious injury.

102 Autom atic Tran smi ssi on
-When the selector lever is in a driving
position, the veh icle may creep, even at
id le speed. Therefore do not release
the park ing brake or foot brake until
you are ready to move, because power
is transmitted to the wheels as soon as
a driving posit ion is engaged.
- Do not accelerate while selecting a
driving position. At this time the en­
g ine must be at idle speed so that un­
d ue stress is no t placed on the clutches
in the t ransmission.
- Remembe r: Even when stopped briefly
with the automatic transmission in D/S
or R, engine power is being transmit ­
ted to the whee ls. Yo ur vehicle could
"creep" forward or backward . When
stopped, keep the brake peda l fully de­
pressed and use the parking brake if
necessary to keep the vehicle from roll­
ing .
-If the selector lever is unintentionally
moved into N wh ile you are driving, take
yo ur foot off the accele rator pedal and
wa it for the engine to return to idle
speed befo re selec ting a drivi ng position.
- Never shift into R or P when the veh icle is
in mo tion.
- Never get out of the dr iver's seat when
the engine is runn ing.
- If you must get out of the vehicle, move
the se lector lever securely into the P po­
si ti on a nd apply the park ing brake fi rm ly.
- If the eng ine must remain running, never
have any driv ing pos ition engaged when
chec king under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake
firmly set¢
page 214, Engine comport­
ment .
Otherwise, any increase in engine
speed may set the vehicle in mot ion,
even with the parking brake applied.

At speeds above about 3 mph (5 km/h) the
Automatic Shift Lock is automatically deacti­
vated in the
N position.
I nte rlock butt on
The lock button on the selector lever prevents
the lever from being acc identally shifted into
certain positions. Pressing this button deacti­
vates the se lector lever lock. Depending on
the direction of the shift, the se lector lever
locks at different positions. The positions are
h ighlighted in the illustration
c:> fig. 107.
Kick-down
App lies to vehicles: with multitronic
The kick-down feature allows the vehicle to
generate maximum acceleration.
When you depress the accelerator pedal be­
yond the resistance point, the transmission downshifts into a lower gear ratio depending
on the vehicle speed and engine speed. As long as the accelerator pedal is depressed, the
engine speed is automat ically regulated for
maximum acceleration.
A WARNING
Be ca reful when using the kick-down fea­
ture on slippe ry roads. Rapid acce lerat ion
may cause the vehicle to skid.
Dynamic shift program (DSP)
Applies to vehicles: with multitr on ic
The automatic transmission is electronically
controlled.
The transmission is self adapting and will au­
tomat icall y
select the best shift program su it­
ed to the driving condit ions and d riving s tyle.
The transmission will se lect one of the
econo­
my
programs when you drive at a steady
speed or a gradually chang ing speed without
heavy acceleration . T h is ach ieves optimum
f u e l efficiency, with early upshifting and de­
layed downshifting .
The transmission will a utomat ica lly select the
s porty shift prog rams whe n you drive at high- er speeds, or with heavy acceleration and fre­
quently changing speeds. Upshifts are delayed
to make full use of engine power . Downshift­
ing takes place at higher engine speeds than
in the economy programs.
The selection of the most suitable s hift pro ­
gram is a continuous, automatic process. The
driver can a lso make the transm iss ion sw itch
to a sporty program by
qu ick ly pressing down
the gas pedal.
This causes the transm ission to shift down to
a lower gear to ach ieve rapid acce lerat ion, e.g.
for quickly passing another vehicle. You do not need to press the gas pedal into the kick-down
range. After the transm ission has upshifted,
the or iginal program is selected according to
you r dr iv ing style .
An additional sh ift program allows the auto ­
matic transmission to select the proper gea r
for uphill and downh ill grad ients.
This keeps the transm ission from shifting up
and down unnecessarily on hills. The trans ­
mission will sh ift down to a lower gear when
the driver presses the brake pedal on a down­
hill g radient. This ma kes use of the braking ef­
fect of t he engine w ithou t the need to s hift
down man ually .

Manual shift program
Applies to vehicles: with multitronic
Using the manual shift program you can
manually select gears .
Fig. 108 Center console: shi ftin g th e tip tronic ma nua l·
l y
Fig. 109 Display: man ual sh ift program, selected gea r
highl ighted
Switching to manual shift program
• Push the selector lever to the right from 0/

over, the selected gear appears in the dis­
play.
To upshift
• Push the selector lever forward to the plus
pos ition
0 ~ fig . 108 .
To downshift
• Push the leve r to the minus position 0 -
When accelerating , the transmission will au­
tomatically shift into the next gear before the
engine reaches its maximum RPM .
If you apply a light throttle when accelerat­
ing, tiptron ic will automatically shift from 1st
to 2nd gear to save fuel. If you apply a heavy
thrott le, the transmission will stay in 1st gear
Automatic Transmission 105
until near maximum RPM is reached, or until
the driver shifts into 2nd gear.
If you take your foot off the accelerator pedal
when d riving down a steep incline, tiptronic
will downshift from the selected gear into the
next lower gear until it reaches 1st gear,
based on road speed and engine RPM. Auto­
matic downshifting is interrupted as soon as
you apply the throttle again.
(D Tips
- When you shift into the next lower gear,
the transmission will downshift only
when there is no possibility of over-rev­
ving the engine.
- When the kick-down comes on, the
transm ission w ill shift down to a lower
gear, depending on vehicle and engine
speeds .
- tiptronic is inoperative when the trans­
mission is in the fai l-safe mode.
Steer ing wheel with tiptronic
