_& WARNING
• Unintended vehicle movement can cause serious injury.
- When the selector lever is
in a driving position, the vehicle
may creep, even at idle speed. Therefore do not release the
parking brake or foot brake until you are ready to move,
because power is transmitted to the wheels as soon as a driving
position is engaged.
- Do not accelerate while selecting a driving position. At this
time the engine must be at idle speed so that undue stress is
not placed on the clutches in the transmission.
- Remember : · even when stopped briefly with the automatic
transmission in "D" or "R", engine power is being transmitted
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 lever is unintentionally moved into N while you
are driving, take your foot off the accelerator pedal and wait for
the engine to return to idle speed before selecting a driving posi­
tion .
• Never shift into "R" or "P" when the vehicle is in motion.
• Never get out of the driver's seat when the engine is running.
• If you must get out of the vehicle , move the selector lever
securely into the P position and apply the parking brake firmly.
• If the engine must remain running, never have any driving
position engaged when checking under the hood. Make sure the
selector lever has securely engaged and is locked in "P" with the
parking brake firmly set~
page 281, "Engine compartment ".

Automatic selector lever lock
The se lector lever is locked in the P and N positions when the ignition
is turned on. To move the lever from these posit ions 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 foot brake while selecting gear
A time delay element prevents the selector lever from lock ing 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 (Neutra l) for
more than approximately
l second, w ithout the brake pedal being
pressed.
At speeds above about 3 mph (5 km/h) the Automat ic Shift Lock is
automatically deactivated in the
N position.
Interlock button
The lock button o n 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 pos itions are
highlighted in the illustration ~
page 156, fig. 170.
Ignition key safety interlock
The key cannot be removed from the ignition un less 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.•
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
Controls and equip­
ment Safety first
as you cont
inue to press the accelerator pedal beyond this resistance
point.
& WARNING
Be careful when using the kick -down feature on slippery roads.
Rapid acceleration may cause the vehicle to skid. •
Dynamic shift program (DSP)
The automatic transmission is electronically controlled.
The transmission is self adapting and will automatically select the
best sh ift p rogram su ited to the driv ing cond it ions and driving style.
The transmission will select one of the
economy programs when you
drive at a steady speed or a gradually changing speed without heavy
acceleration . This ach ieves optimum fuel efficiency, with early
upshifting and delayed downshifting.
Th e transmission will automatically select the
sporty shift programs
when you dr ive at higher speeds, or w ith 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 select ion of the most suitable shift program is a cont inuous,
automatic p rocess. The driver can also make the transmission switch
t o a spo rty program by
quickly pressing down the gas pedal.
Th is causes the transmission to shift down to a lower gear to achieve
rap id acceleration, e.g . for quickly passing another vehicle. Yo u do
not need to press the gas pedal into the kick -down 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 uph ill and downhill gradients.
Th is prevents the transmission from upshifting and downshifting
unnecessari ly on hills. The transmission will shift down to a lower _,.

=> fig. 172.
To upshift
-Push the selector lever forward to the plus position 0
=> fig. 171 .
To downshift
-Push the lever to the minus position Q.
When accelerating, the transmission will automatically shift into
gears 1, 2, 3, 4 or 5 before the engine reaches its maximum RPM .
I f you apply a light throttle when acce lerating, t iptronic ® will auto­
matically shift from 1st to 2nd gear to save fuel.
If you apply a heavy
throttle, the transmission will stay in 1st gear until near maximum
RPM is reached, or unt il the dr iver shifts into 2nd gear .
I f you take your foot off the accelerator pedal when driving down a
steep incline, tiptronic ® will downsh ift from the se lected gear into
the next lower gear until it reaches 1st gear , based on road speed and
engine RPM. Automatic downshifting is interrupted as soon as you
apply the th rottle again.
lI] Tips
• When you shift into the next lower gear, the transmission will
downshif t only when there is no possibility of over- rewing the
eng ine.
• When the kickdown comes on, the transmission will sh ift down to
a lower gear, depending on vehicle and eng ine speeds.
• Tiptronic ® is inoperative when the transmission is in the fail-safe
mode. •

Homelink ®
Universal remote control
Applies to veh icles: w ith Hom eli nk ® universal remote control
General information
The Homelink ® feature can learn up to three radio
frequency codes for most current transmitters used for
operating garage doors, estate gates, home or outdoor
lighting systems, and other devices.
You must first program the Homelink ® transm itter before you can
use the system=>
page 182, "Programming the Home link® trans­
mitter".
I n order to program the Homelink ® transmitter for devices utilizing
rolling code, a second person on a ladder who can safe ly reach the
garage door opener motor is recommended. It is also necessary to
locate the "learn" button on your garage door opener motor. Refer to
the operating instructions for the opener, as the location and color of
this button may vary by manufacturer.
You can still use the original remote control for the device at any
time.
& WARNING
• Never use the Homelink'"' transmitter with any garage door
opener that does have not the safety stop and reverse feature as
required by federal safety standards. This includes any garage
door opener model manufactured before Aprill, 1982.
• A garage door opener which cannot detect an object, signaling
the door to stop and reverse does not meet current federal safety
standards. Using a garage door opener without these features
increases risk of serious injury or death.
Controls and equip ­
ment Safety first
& WARNING
(continued)
• For safety reasons never release the parking brake or start the
engine while anyone is standing in front of the vehicle.
• A garage door or an estate gate may sometimes be set in
motion when the Homelink ® remote control is being
programmed. If the device is repeatedly activated, this can over­
strain motor and damage its electrical components -an over­
heated motor is a fire hazard!
• To avoid possible injuries or property damage, please always
make absolutely certain that no persons or objects are located in
the range of motion of any equipment being operated.
