- Do not accelerate while sele cting a driving pos ition. At this
time the engine mu st be at idle speed so that undue stre ss is
not placed on the clutches in the transmiss ion .
- Remember: Even when stopped briefly with the automatic
transmission in D ,S or R, engine power is being transmitted to
the wheels. Your vehicle could "creep " forward or back ward .
When stopped , keep the brake pedal fully depressed and use
the parking brake if necess ary to keep the vehicle from rolling.
• If the selector lever i s unintentionally moved into N while you
are driving, take your foot off the accele rator pedal and wait for
the eng ine to return to idle speed before selecting a dr iving posi­
tion.
• Never shift into R or P when the vehicle is in mot ion .
• Never get out of the driver 's seat when the engine is running .
• If you mu st get out of the vehicle , move the selector lever
securely into the
P pos ition and apply the parking brake firmly .
• If the engine must remain running , never have any driving po si­
tion engaged when che cking under the hood. Make sure the
selector lever has securely engaged and is locked in
P with the
parking brake firmly set~ page
263 , "Engine compartment ".
Otherwise , any increase in engine speed may set the vehicle in
motion , even with the parking brake applied. •

App lies to vehicles : with automat ic transm ission
Dynamic shift program (DSP)
The aut omatic transmission is electronically controlled.
The transmission is se lf adapting and will a ut oma tica lly se lect the
best shift program suited to the driving conditions and driving style.
The transmission will select one of the
eco nom y programs when
you drive at a steady speed or a g radually changing speed without
heavy acceleration. This achieves optimum fuel efficiency, with early
upshifting and delayed downshifting.
The transmission will automatically select the
s p ort y shift programs
when you drive at higher speeds, or with heavy acceleration and
frequent ly 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 se lect ion of the most su itable shift program is a continuous,
automatic process. The driver can also make the transmission
sw itch to a sporty program by
quick ly pressing down the gas peda l.
This causes the transmission to shift down to a lower gear to
achieve rapid acceleration, 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 original program is
selected accord ing to your driving sty le.
An additiona l shift program allows the automatic transmission to
select the proper gear for uph ill and downhi ll gradients. ..,.

This keeps the transmission from shifting up and down unneces­
sari ly on hills. The transmission will shift down to a lower gear when
the driver presses the brake pedal on a downhi ll gradient. This
makes use of the braking effect of the engine without the need to
shift down manually. •

When accelerating , the transmission will automatically shift into the
next gear before the engine reaches its maximum RPM .
If you apply a light throttle when accelerating, tiptronic wi ll au to­
matically shift from 1st to 2nd gear to save fuel. If you apply a heavy
throttle, the transmission will s tay in 1st gear until near maximum
RPM is reached, or unti l the driver shif ts into 2nd gear.
If you take your foot off the accelerator peda l when driving down a
steep inc line, tiptronic wi ll downshift from the selected gear into
the neX1 lower gear until it reaches 1st gear, based on road speed
and engine RPM. Automatic downshifting is interrupted as soon as
you apply the thrott le again .
[ i ] Tips
• When you shift into the next lower gear, the transmission will
downshift only when there is no possibi lity of over -revving the
engine .
• When the kick-down comes on , the transmission wil l shift down
to a lower gear , depending on vehicle and engine speeds .
• tiptron ic is inoperative when the transmission is in the fa il-safe

Do-it-yourself service Technical data

The system operates across the entire speed range in combination
with the ABS system. If the Anti -Lock Brake System (ABS) ma lfunc­
tions, the ESP wil l also shut down .
How the system works
The Anti -Lock Brake System (ABS), Electronic Differential Lock (EDU
and the Anti -Slip Regulation System (ASR) are integrated in the elec­
tronic stabilization program. In addition to the data provided by
th ese functions, the ESP control unit requires additional measure ­
ment data provided by high performance sensors . The rotational
speed of the vehicle about its vertica l axis, vehicle acceleration in
the fore-and-aft and lateral directions , the brake pressure, and the
steering angle are all measured.
The direction in which the driver wishes to travel is determined with
the aid of the steering angle and vehicle speed and is continua lly
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehicle starts hydrop laning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the prob lem.
The vehicle is then stabi lized by the forces acting on the whee l
during braking. If the vehicle is
oversteering (the vehicle turns too
sharply and the rear wheels slide toward th e ou tside of a curve), the
brakes are main ly app lied on the wheel that is on the outside of the
curve . In the case of a vehicle that is
understeering (the vehicle does
not turn sharply enough and pushes out of a curve), the brakes are
applied as needed on the wheel that is on the inside of the curve or
additional ly on the other wheels. An acoustic signal indicates when
ESP brake app lication cuts in=>&.
T he system operates across the entire speed range in combination
with the ABS system =>
page 238. If the Anti-Lock Brake System
(ABS) malfunctions, the ESP will be out of action as well.
Activating
When you turn on the engine, ESP will automatica lly be activated
and will perform a se lf-test. As soon as the test is comp leted, the
system is in norma l operating mode.

required by pressing the::::>
page 234, fig. 215 ::::> page 234, fig. 214
button . When they are activated, the message
ESP /ASR on appears
briefly in the display .
Deactivating
The ESP should normally be activated al l the time. If necessary, you
can deactivate Anti -Slip Regu lation (ASR) or the Electronic Stabiliza­
tion Program (ESP) by pressing the button=>
page 234, fig. 215.
• Deactivating ASR: Tap the button . In certain exceptional situa­
tions (e .g. driving with tire chains), the Anti-Slip Regulation (ASR)
can be deactivated =>

& WARNING
The Electronic Stabilization Program is nevertheless subject to the
laws of physics . It is particularly important to pay attention to this
fact on wet and slippery roads. It is therefore important that you
always adapt your driving to the condition of the road and traffic
conditions. Do not allow the increased safety provided by the Elec­
tronic Stabilization Program system to lull you into accepting
additional safety risks. •
Electronic differential lock (EDL)
---------
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differential lock (EDU helps the car to start moving,
acc elerate and c limb a gradient on surfaces providing poor or

---""'------------ ....::....:...:~---------------------------
almost no grip. Without EDL, this would be difficult, if not impos­
sible.
How the system works
The EDL operates automatically. It monitors the rotational speed of
wheels with the help of the ABS sensors=:,
page 238 . If a noticeable
slip is detected at the wheels (e.g. on slippery ground on one side),
the spinning wheels are braked and power is transferred to the
other wheels. This is done up to a speed of about 60 mph (100 km/h).
Noises from the brake system signal that wheel spin is being
controlled.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface
with less grip, apply
plenty of throttle until the car starts to move.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads on this wheel, the EDL cuts out tempo­ rarily. The vehicle remains operational and behaves in the same way
as a vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto ­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your ability to control your car. Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning . This is
indicated by the ABS warning light=:,
page 15. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP) . When the vehicle starts up and acceler ­
ates, the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface.
How the system works
ASR performs automatically , i.e. without the driver's intervention .
With the aid of the ABS sensors=:,
page 238, ASR monitors the
speed of the driven wheels. If the wheels start to spin, engine torque
is reduced automatically until the tires find enough grip to lock onto
the road surface. The system is active across the entire speed range.
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Activating
The ESP is automatically activated when the engine is started and it
performs a self-test . You can activate a deactivated ASR if required
by pressing the=:,
page 234, fig. 215 button. When it is activated,
the message
