Applies to vehicles: with mult it ro nic ® Continuously Variable T ransmiss ion (CVT)
General information
Your vehicle is equipped with a electronically controlled continuous ly
var iable transmission (multitronic ®). Inside the multitronic ® system,
the gear ratios are not shifted in finite steps as in a conventional auto­
matic transm ission, but rather
continuously. As a result, engine
power is applied smoothly and comfortably, and better fuel economy
is achieved.
The transmission selects the appropriate gear ratio (upshifts and
downsh ifts) automatically based on set driving programs
=> page 159, "Dynamic shift program (DSP)" .
You can also manually select a shift program (tiptronic ®)
=> page 159 .
You should note, that the multitronic transmission differs from a
conventional Automatic Transmission. In the multitronic transmis ­
sion the engine power is transferred via a link-plate chain, rather than
by a conventiona l torque converter . The multitronic transmission
great ly reduces vehicle "creep" when at a standstill and the transmis­
sion is in
D Sor R. •

& WARNING
• Unintended vehicle movement can cau se serious injury.
& WARNING (c on tinued )
-When the selecto r lever is in a dri ving pos ition, the vehicle
may creep , even at idle speed. Therefore do not relea se the
parking brake or foot brake until you are ready to move ,
becau se power is transmitted to the wheels a s soon as a driving
position i s engaged.
- Do not a ccelerate while selecting a driving p osition. At this
time the engine must be at idle sp eed so that undue stress is
not placed on the clutche s in the transmi ssion.
- Remembe r: • even when stopped briefly with the automatic
transmi ssion in "D ", "S " or "R ", engine power i s being trans·
mitted to the wheels . Your vehicle could "creep " forward or
backward . When stopped, keep the brake pedal fully
depressed and use the parking brake if necessary to keep the
vehicle from rolling .
- If the selector le ver is unintentionally moved into N while
y ou are driving , take your foot off the accelerator pedal and
wait for the engine to return to idle sp eed before selecting a
driving position.
- Never shift into "R " or "P " when the vehicle i s in motion .
- Never get out of the driver 's seat when the engine i s running .
- If you must get out of the vehicle , move the selector le ver
s ecurely into the P position and apply the parking brake firmly.
- If the engine must remain running , never have any driving
position engag ed when checking under the hood. Make sure
the selector lever has securely eng aged and is locked in "P"
with the parking brake firmly set=>
page 272, "Engin e
compartment ". Otherwise, any increase in engine speed may
s et the vehicle in motion, even with the parking brake
applied. •

Automatic Shift Lock (ASL)
The Automatic Shift Lock safeguards you against acci­
dentally shifting into a forward or the reverse gear and
causing the vehicle to move unintentionally.
Fig . 161 Shift gate:
selector lever lock posi­
tions and interlock
button highlighted
The selector lever lock is released as follows:
- Turn the ignition on.
- Step on the brake pedal.
At the same time press and hold
the interlock button on the side of the gear selector knob
=:> page 158, fig. 161 with your thumb until you have
moved the selector lever to the desired position.
Automatic selector lever lock
The selector lever is locked in the P and N positions when the ignition
is turned on. To move the lever from these positions the driver must
depress the brake pedal. As a reminder to the driver, the following warning appears
in the instrument cluster display when the selector
is in
P and N:
When stationary apply footbrake while selecting gear
A time delay element prevents the selector lever from locking when
it is moved through the
N position (going from R to D). The locking
element will lock the selector lever if the lever is left in N (Neutral) for
more than approximately 1 second, without the brake pedal being
pressed.
At speeds above about 3 mph (5 km/h) the Automatic Shift Lock is
automatically deactivated in the
N position.
Interlock button
The lock button on the selector lever prevents the lever from being
accidentally shifted into certain positions. Pressing this button deac­
tivates the selector lever lock. Depending on the direction of the
shift, the selector lever locks at different positions. The positions are
highlighted in the illustration~
page 158, fig. 161.
Ignition key safety interlock
The key cannot be removed from the ignition unless the selector lever
is in the
P park position. When the ignition key is removed, the
selector lever will be locked in the
P position. •
Applies to veh icles: with mu lt it ron ic ® Cont inuously Variable Transm ission (CVT)
Kick-down
The kick-down feature allows the vehicle to generate
maximum acceleration.
When you press the accelerator pedal beyond the resistance point
that is reached at full throttle, the transmission will select a lower
gear ratio based on vehicle speed and engine RPM. The engine RPM
will be controlled to produce maximum vehicle acceleration as long
as you continue to press the accelerator pedal beyond this resistance
point. ..

____________________________________________________ T _r_a _n_ s_m _ i_s _s_ i_ o _ n _ ___._
& WARNING
Be careful when using the kick-down feature on slippery roads.
Rapid acceleration may cause the vehicle to skid.•
Appli es to vehi cles: wit h mul tit ro nic ® Con tin uousl y Va riable Tra ns mi ssion (CVT )
Dynamic shift program {DSP)
The multitronic ® transmission is electronically
controlled.
The transmission selects the appropriate gear ratio (upshifts and
downshifts) automatically based on preset driving programs.
The transmission will select one of the
economy programs when you
drive at a steady speed or a gradually changing speeds without heavy
acceleration . This gives best fuel efficiency, with early upshifting and
delayed downshifting .
The transmission will automatically select the
sporty shift programs
when you drive at higher speeds, or with heavy acceleration and
frequently changing speeds . Upshifts are delayed to make full use of
engine power . Downshifting takes place at higher engine speeds than
in the economy programs.
The selection of the most suitable shift program is a continuous,
automat ic p rocess . The driver can also make the transmission switch
to a sporty program by
quickly pressing down the gas pedal.
This causes the transmission to shift down into a lower gear ratio and
makes quick acceleration possible (to pass another vehicle) You do
not need to press the gas pedal into the kickdown range . After the
transmission has upshifted, the original program is selected
according to your driving style.
An additional shift program allows the automatic transmission to
select the proper gear for uphill and downhill gradients.
This prevents the transmission from shifting up and down unneces­ sarily on hills. The transmission will shift down to a lower gear ratio
Con tro ls a nd e quip ­
m en t Vehicle
OP-eration
when the driver presses the brake pedal on a downhill gradient . This
makes use of the braking effect of the engine without the need to
shift down manually.
If you are driving in h ills and mountains, the transmission will contin­
uously adjust the gear ratio to the road grade. If you press the brake
pedal when driving downhill, the transmission will downshift auto­
matically. This increases the braking effect of the engine.
If the cruise control is on when you are traveling downhill, the trans­
mission will automatically select a lower gear ratio in order to main ­
tain the set vehicle speed. This will cause the engine speed to
increase. •

Switching to manual shift program
- Push the selector lever to the right from D. As soon as the
transmission has switched over, the selected gear appears
in the display~ fig. 163.
To upshift
-Push the selector lever forward to the plus position
~ page 159, fig. 162 G).
To down shift
- Push the lever to the minus position Q.
When accelerating , the transmission will automatically shift into the
next higher gear before the engine reaches the maximum RPM.
Wh en accelerating, if you apply a light thrott le, the tiptronic ® will
automatically shift into the next higher gear to save fuel. If you apply
a heavy throttle, the transmission will stay in gear engaged until near
maximum RPM are reached, or until the driver manua lly shifts into a
higher gear.
If you take your foot off the accelerato r pedal when driving down a
steep incline , the tiptronic ® will downshift from the selected gear
into the next lower gear based on road speed and engine RPM. The
automatic downshifting is interrupted as soon as you apply throttle
again .
[I] Tips
• When you shift into the next lower gear, the engine w ill downshift
only when there is no possibility of over-revving .
• When the kick-down comes on, the transmission will sh ift down to
a lower gear depending on vehicle and engine speeds.
• The tiptronic ® is inoperative when the transmiss ion is in the fail­
safe mode .•
