(I] Tips
• You can apply the parking brake at any time -even with the igni­
tion turned off. The ignition must be turned on in order to release the
parking brake.
• Occasional noises when the parking brake is applied and released
are normal and are not a cause for concern.
• Th e parking brake goes through a se lf-test cycle at regular inter­
vals -when the vehicle is parked. Any associated noises are normal. •
Parking
To prevent a parked vehicle from rolling away, there are
a few things you should do.
When you park your vehicle, do the following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- Move the selector lever into the
P position==> &.
- Switch off the engine and remove the ignition key from
the ignition lock .
When you park your vehicle on hills, do the
following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- If you are parking headed
downhill, turn the front wheels
toward the curb. -
If you are parking headed
uphill, turn the front wheels
away from the curb.
- Move the selector lever into the
P position.
- Switch off the engine and remove the ignition key from
the ignition lock.
& WARNING
This is how you can reduce the risk of injury when leaving your
vehicle.
• Never park the vehicle where it can come in contact with dry
grass, spilled fuel or any other flammable materials.
• When parking on hills, always turn the wheels so that the front
wheels will first roll into the curb, if the vehicle should start to
roll.
• Never allow anyone -especially small children -to remain in
the vehicle when it is locked. Locked doors make it more difficult
for rescuers to access the passenger compartment in the event of
an emergency. Danger to life!
• Never leave children unsupervised in the vehicle. Children
could release the parking brake or move the gearshift lever out of
gear. The vehicle could start to roll away and cause an accident.
• No matter what the season is, the temperature in a parked
vehicle can reach dangerous levels.
0 Note
• Please exercise care when you park your vehicle in parking areas
with parking barriers or curbs. Parking barriers and curbs vary in
height and could damage your bumper and related components as
the front of your vehicle moves over a barrier or curb that is too high,
as you park or as you back out of a parking spot. In order to be sure
that no such damage can occur, you may wish to stop short of having
the front tires of your car touch the parking barrier or curb. .._

The display=> page 116, fig. 106 will show the set speed. The display
may vary depending on the type of display in your vehicle. T he indi­
cator light

in the instrument cluster.
The speed is kept constant via an engine output adjustment or active
brake intervention.
_& WARNING
• Always pay attention to traffic even when the cruise control is
switched on. You are always responsible for your speed and the
distance between your vehicle and other vehicles.
• For safety reasons, the cruise control should not be used in the
city, in stop-and-go traffic, on twisting roads and when road
conditions are poor (such as ice, fog, gravel, heavy rain and hydro­
planing ) - risk of accident.
• Turn off the cruise control temporarily when entering turn
lanes, highway exit lanes or in construction zones.
• Please note that inadvertently "resting" your foot on the accel­
erator pedal causes the cruise control not to brake . This is because
the cruise control is overridden by the driver's acceleration .
(I] Tips
The brake lights illuminate as soon as the brakes decelerate
automatically . •

Change speed
in increments of 1 mph (1 km/h) by lightly pressing the
lever. If you keep the lever pressed down, yo u will alter your speed in
5 mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your speed, e .g . if you want to pass someone. The speed you saved earlier wi ll
resume as soon as you release the accelerator pedal.
If, however, you exceed yo ur saved speed by 5 mph (10 km/h) for

Adaptive Cruise Control -
----------------
In certain situations, the braking power of the Adaptive Cruise
Control is not enough to maintain an adequate distance to the vehicle
up ahead. In these situations, the Adaptive Cruise Control calls the
driver to take action.
The
driver intervention prompt alerts you visually and audibly to take
over.
• A red vehicle is shown in the instru ment cluster display
=>
page 130, fig. 118.
• Th e text
DISTANCE! appears in the status line.
• The indicator light
c:::>uuc:::> in the speedometer blinks red.
• A warning tone sounds .
[I) Tips
• If the Adaptive cruise control initiates braking, the hydraulic brake
system is under pressure . Therefore, the brake pedal distance is
shorter and the pedal "feels" harder .
• Adaptive Cruise Control is switched
off after pressing the foot­
brake. The speed saved up this point can be resumed.
• To resume the saved speed, release the brake pedal and press the
control lever=>
page 124, "Turning Adaptive Cruise Control off
temporarily".
• If you use the accelerator to go faster than the speed of the
vehicle ahead of you, the
driver intervention prompt will not be
accompanied by a warn ing s ignal.
• If the speed you previously set is exceeded, the indicator light in
the speedometer will switch
off .•

_& WARNING
• Unintended vehicle movement can cau se 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 transm itted to the wheels as soon as a driv ing
po sition i s engaged.
- Do not accelerate while selecting a driv ing position . At this
time the engine must be at idle speed so that undue stress i s
not placed on the clutches in the transm iss ion.
- Remember : • even when stopped briefly with the automatic
transmission in "D", "S" or "R" , engine power is being trans­
mitted to the wheels . Your vehicle could "creep " forward or
backward. When stopped, keep the brake pedal fully
depre ssed and use the parking brake if neces sary 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 d river's seat when the engine is running.
• If you must get out of the vehicle , move the selector lever

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 .
& WARNING
Be careful when using the kick-down feature on slippery roads.
Rapid acceleration may cause the vehicle to skid. •

The automatic transmission is electronically controlled.
The transmission is self adapting and will automatically select the
best sh ift p rogram suited to the driv in g conditions 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 de layed 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 . Downsh ifting takes place at higher engine speeds than
in the economy programs . _.,

The selection of the most suitable shift program is a continuous,
automatic process. 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 to a lower gear to achieve
rap id acceleration, e.g . for quic kly passing another vehicle. You do
not need to press the gas peda l 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 downh ill gradients .
This keeps the transmission from shifting up and down unnecessarily
on hills . T he transmission will shift down to a lower gea r 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. •

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.
If you apply a light throttle when acce lerating, tiptronic ® wi ll 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 until the driver shifts into 2nd gear.
If you take your foot off the accelerator pedal when driving 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. Automatic downshift ing is interrupted as soon as you
apply the throttle again . _.

General information
Your vehicle is equipped with a electronically controlled continuously
variable transmiss ion (multitronic ®). Inside the multitronic ® system,
the gear ratios are not shifted in finite steps as in a conventional auto­
matic transmission, but rath er
continuously. As a result, engine
power is applied smoothly and comfortably, and better fuel economy
is achieved .
The transm ission selects the appropriate gear ratio (upshifts and
downshifts) automatically based on set driving programs
~ page 156, "Dynamic shift program (DSP)".
You can also manually select a shift program (tiptronic ®)
~ page 157.
You should note, that the multitronic transmission differs from a
conventional Autom ati c Transmission . In the multitronic transmis­
sion the engine power is transferred via a link-plate chain, rather than
by a conventional torque converter. The multitronic transmission
greatly reduces vehicle "creep" when at a standstill and the transmis­
sion is in
D Sor R . •
