Setting distance
Increasing distance
-Push the slider switch once to the right 0 ~ fig. 166. The
distance currently set is shown for 3 seconds in the instrument cluster display.
Cruise Control accelerates to reach the desired speed if no slower
vehicle ahead is detected.
& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injuries.
• Never resume the stored speed if the speed is too high for
prevailing road, traffic or weather conditions.
[ i ] Tips
When the system is turned off temporarily, the speed set at that
time is stored. •
- Push the slider switch again to the right 0 to increase
the distance by one step.
Reducing distance
Push the slider switch once to the left Q. The distance
currently set is shown for 3 seconds in the instrument
cluster display.
- Push the slider switch
again to the left Oto decrease the
distance by one step .
The distance at which the Adaptive Cruise Control follows a vehicle
in front is determined by
time intervals. A time interval to a vehicle
in front is established and maintained . This produces a speed­
dependent interval. The higher the speed, the greater the safety
interval in feet (meters)

& WARNING
Following other vehicles too closely increases the risk of a crash
and serious personal injury .
• Following other vehi cles too closely , particularly at h igher
speeds increases the risk of colli sions and serious personal injury.
• Setting short distances to the traffic ahead reduces the time
and distance available to bring your vehicle to a safe stop and
makes it even more necessary to pay close attention to traffic .
• Always select a speed and distance to traffic ahead that is safe
and appropriate under the prevailing traffic , road , weather and
lighting conditions .
• Never rely on the distan ce control feature of ACC alone to
prevent rear-end collisions. Always be prepared to brake and take
evasive action to avoid collisions and other acc ident situations .
• Never allow the closing speed between you and other vehicles
to be so h igh that the Adaptive Cruise Control may not be able to
slow your vehicle safely. If closing speed is too high , you must
apply the brakes yourself to reduce the risk of a rear-end crash .
• Always select a greater following distance to the vehicle ahead
on wet roads than on dry roads .
• Always re ad and heed the informat ion and WARNINGS ::::>

tained. The ACC system is not switched off, and increased attention
to the traffic situation is absolutely necessary. The following may be
reasons why the message
ACC functionality limited appears:
• The ACC sensor is dirty . The ACC system is not reacting, or is not
reacting correctly, to moving vehicles up ahead in your lane of
travel.
• There may be very light traffic on and there is nothing that marks
the side of the road (for example, guard rails, traffic signs, trees). As
soon as a moving vehicle up ahead is detected again, ACC becomes
active again and the message disappears .
The ACC sensor is located behind the area to the right of the front

General information
The radar sensor has limits that the driver must know to
be able to use ACC properly.
The Adaptive Cruise Control works within limits that ar e also related
to radar sensor range and sight distance . In some situations ACC
may react unusually or late from the driver's point of view . There ­
fore, always be attentive to what is happening around you and always be ready to intervene, if necessary :
• when driving around curves=>
page 166
• when vehicles up front are not in line with your vehicle
=>
page 166
• when other vehic le s are changing lanes=> page 167

page 184.
Before you move the selector lever to R, press both the button in the
handle of the selector lever
and the brake pedal at the same time.
When the ignition is on, the backup lights illuminate when the
selector lever is moved into R.
N -Neutral
The transmission is in neutral in this position. Shift to this position
for standing with the brakes applied =>
page 186 .
When the vehicle is stationary or at speeds below 3 mph (5 km/h),
you must always apply the footbrake before and while moving the
lever out of
N.
D -Normal position for driving forward
Position Dis for normal city and highway driving. It ranges from zero
to top speed and all gears shift automatically, depending on engine
load, driving speed and automatically selected shift programs.
When the vehicle is stationary or at speeds below 3 mph (5 km/h),
you must always apply the foot brake before and while moving the lever to
D out of N.
In certain circumstances it may be advantageous to temporarily
switch to the manual shift program to manually select gear ratios to
match specific driving conditions=>
page 788.
S -Sport position
Select this position for sportier performance. In this position, the
transmission will not upshift as soon, allowing the vehicle to use the
increased power available at higher engine speeds to achieve live­
lier acceleration.
When the vehicle is stationary or at speeds below 3 mph (5 km/h),
you must always apply the foot brake before and while moving the lever to
S out of N.
& WARNING
Read and follow all WARNINGS => & in "Driving the automatic
transmission" on

When accelerating, the transmission will automatically shift into
gears 1 , 2, 3, 4 or 5 before the engine reaches its maximum RPM .
If you apply a light throttle when accelerating, tiptronic® will auto ­
matically sh ift from 1st to 2nd gear to save fue l. If you app ly a heavy
throttle, the transmission will stay in 1st gear until near maximum
RPM is reached, or unti l the driver shifts into 2nd gear .
If you take your foot off the accelerator peda l when driving down a
steep incline, tiptronic® wi ll downshift from the selected 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 thrott le again .
[ i ] Tips
• When you shi ft into the next lower gear, the transmission will
downshift only when there is no possibi lity of over -revving the
engine.
• When the kickdown comes on, the transmission wil l shift down
to a lower gear, depending on vehicle and eng ine speeds.

tendency to spin and the vehicle may break away -danger of skid­
ding!
• Stability is limited in the ESP offroad mode. •
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,
accelerate and climb 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 292. 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 22. •
Anti-Slip Regulat ion 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 292, 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 . ..,

If an individual wheel begins to rotate too slowly in relation to
vehicle speed and tends to lock, the ABS automatically reduces
brake pressure to prevent that wheel from locking.
This automatic adjustment process will cause a
slight vibration of
the brake pedal and some noises to alert you that vehicle speed
must be adapted to existing road and traffic conditions .
_& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics.
[ i] Tips
• If ABS is not functioning properly , a warning light will come on .
See
=> page 22.
• If a fault occurs in the ABS, the EDL is also not functioning. This
is indicated by the ABS warning light.•
Brake assistant
The brake assistant is designed to achieve the optimum
braking effect.
The brake assistant helps to increase the effective braking power
and thus to achieve
a shorter stopping distance . If the driver
presses the brake pedal very quickly , the brake assistant automati­
cally boosts the braking force to the maximum level, up to the point
where the anti-lock brake function (ABS) intervenes to stop the
wheels from locking. You should then keep th e brake pedal pressed
until the vehicle has braked to the required speed. The brake assis­
tant swi tches its elf off as soon as you release the brake pedal.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
Automatic full braking assist
This function allows full braking
in spite of high brake pedal forces
(e.g . when the brakes are severely stressed because the vehicle is
fully loaded) . The driver notices this function through a reduction of
pedal force and increased pedal travel. When the brake pedal is
released, full braking assist switches off again automatically.
If there is an ABS failure, the brake assistant and automatic full
braking assist ar e not available .
The brake assistant will not be operative if there is a malfunction in
the ABS.
_& WARNING
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow the vehicle ahead of you too closely . Increased risk of an
accident cannot be compensated for even by the brake assistant,
so always maintain a safe speed. iJ
Servotronic® -advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort.
The advanced Servotronic ® power steering system senses the road
speed and electronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
vehicle speed.
Power steering will not work if the engine is off. As a result, the
s teering whe el will be hard to turn.
The power steering fluid level is checked during the scheduled
maintenance services .
