gears, based on the level of acceleration and
speed. The car must be at a standstill when
shifting from position R to position D.
Geartronic–manual shiftingGeartronic allows you to manually shift among
your vehicle's six forward speeds. Geartronic
can be selected at any time.
•To access the manual shifting position
from Drive (D), move the gear selector to
the right (to the area marked M in the illus-
tration.
•To return to the D position from the manual
shifting position, move the gear selector to
the left.
While driving
•If you select the manual shifting position
while driving, the gear that was being used
in the Drive position will also initially be
selected in the manual shifting position.
•Move the gear selector forward (toward
"+") to shift to a higher gear or rearward
(toward "–") to shift to a lower gear.
•If you hold the gear selector toward "–", the
transmission will downshift one gear at a
time and will utilize the braking power of
the engine. If the current speed is too high
for using a lower gear, the downshift willnot occur until the speed has decreased
enough to allow the lower gear to be used.
•If you slow to a very low speed, the trans-
mission will automatically shift down.
Shiftlock – Neutral (N)If the gear selector is in the N position and the
vehicle has been stationary for at least 3 sec-
onds (irrespective of whether the engine is run-
ning) then the gear selector is locked.
To be able to move the gear selector from N to
another gear position, the brake pedal must be
depressed and the ignition must be in posi-
tion II, see page 84.
Geartronic–Sport mode (S)2
This transmission mode provides sportier shift-
ing characteristics and enables a more active
driving style by making it possible to drive at
higher rpm in each gear before shifting up. The
engine also responds faster when the throttle
pedal is pressed.
To access Sport mode from Drive (D), move the
gear selector to the right. The transmission will
not switch to manual shifting mode until the
gear selector is moved forward or rearward
toward + or –.
Sport mode can be selected any time.
NOTE
•On vehicles equipped with Sport mode,
the transmission symbol in the main
instrument panel will change from D to
S when the gear selector is moved to
the manual shifting mode. If the gear
selector is moved toward "+" or "-", the
number of the gear currently being used
will be displayed, see page 77).
•Please be aware that using Sport mode
may result in a slight decrease in fuel
economy. Driving in D can help improve
fuel economy.
Geartronic–starting on slippery surfacesSelecting 3rd gear in Geartronic’s manual shift-
ing mode can help provide better traction when
starting off on slippery surfaces. To do so:
1. Depress the brake pedal and move the
gear selector to the right from the D posi-
tion to the manual shifting position. The
text in the instrument panel display will
change from
D to 1.
2. Press the gear selector forward and
release it (this selects 2nd gear). Press the
selector forward again and release it to
select 3rd gear.

140* Option/accessory, for more information, see Introduction.
When the symbol on the
left side of the display
changes to
, the radar sen-
sor has detected another
vehicle ahead. The distance
to a vehicle ahead is only
regulated when this symbol (
) is illumi-
nated.
Changing the set speedAfter a speed has been set, it can be increased
or decreased by using the
or buttons.
Each time one of these buttons is pressed, the
vehicle's speed changes by 5 mph
(approximately 8 km/h).
When the system is in active mode, the
but-
ton has the same function as
, but results in
a smaller increase in speed.
NOTE
•If one of the Adaptive Cruise Control
buttons is pressed for more than
approximately one minute, ACC will be
deactivated. The engine must then be
switched off and restarted to reset ACC.
•In some situations Adaptive Cruise
Control cannot be put in active mode.
Cruise control Unavailable is shown
in the display, see page 146.
Setting a time intervalThe set time interval to vehicles ahead can be
increased by pressing
and decreased by
pressing
. The current time interval is shown
briefly in the display following adjustment.
Different time intervals can be
selected and are shown in the
display as 1–5 horizontal bars.
The greater the number of
bars, the longer the time inter-
val. One bar represents a time
interval of approximately
1 second; 5 bars is approximately 3 seconds.
At low speeds, when the distance to the vehicle
ahead is short, ACC increases the time interval
slightly. In order to follow the vehicle ahead as
smoothly as possible, ACC allows the time
interval to vary considerably in certain situa-
tions.
WARNING
•Only use a time interval that is suitable
in current traffic conditions.
•A short time interval gives the driver lim-
ited reaction time if an unexpected sit-
uation occurs in traffic.
The number of bars indicating the selected
time interval are shown while the setting is
being made and for several seconds afterward.
A smaller version of the symbol is then shown
to the right in the display. The same symbol is
also displayed when Distance Alert is in active
mode, see page 148 .
Standby mode (temporary deactivation)
Press to temporarily deactivate cruise con-
trol (put it in standby mode). The set speed, for
example 55 mph, is then shown in parenthe-
ses.
The previously set speed and time interval are
resumed by pressing
.
WARNING
There may be a significant increase in speed
after the button has been pressed.
When ACC is in active mode, the vehicle’s
speed increases by approximately 1 mph
(1 km/h) each additional time
is pressed.

Standby mode due to action by the driverACC is temporarily deactivated and put in
standby mode:
•if the brakes are applied
•if the gear selector is moved to N
•if the driver drives at a speed higher than
the set speed for more than 1 minute.
In this happens, the driver will have to regulate
the vehicle's speed.
NOTE
If the accelerator pedal is only depressed for
a short time, such as when passing another
vehicle, ACC is deactivated temporarily and
is reactivated when the pedal is released.
Automatic standby modeAdaptive cruise control is linked to other sys-
tems such as the stability and traction control
system (DSTC). If this system is not functioning
properly, adaptive cruise control is automati-
cally deactivated and will go into standby
mode.
In the event of automatic deactivation, an audi-
ble signal will sound and the message
Cruise
control Cancelled is shown in the display.
The driver must then intervene and adapt thevehicle's speed to the surrounding traffic and
regulate the distance to the vehicle ahead.
An automatic switch to standby mode may be
caused if:
•engine speed (rpm) is too high/low
•the vehicle's speed goes below 18 mph
(30 km/h)3
•the wheels lose traction
•brake temperature is high
•the radar sensor is obstructed by, for
example, wet snow or rain.
Resuming the set speedIf ACC is in standby mode, it can be reactivated
by pressing the
button on the steering
wheel keypad. The vehicle will return to the
most recently set speed.
WARNING
The vehicle may accelerate quickly after has been pressed if its current speed is
considerably lower than the set speed.
Passing another vehicleIf your vehicle’s speed is being regulated by
ACC and the driver indicates that he/she would
like to pass the vehicle ahead by using theleft turn signal, ACC can assist by accelerating
briefly.
This function is active at speeds above approx-
imately 45 mph (70 km/h).
WARNING
Please be aware that this function will also
cause the vehicle to accelerate briefly in
certain situations other than passing
another vehicle, for example using the left
turn signal to indicate a lane change or a
turn toward a highway exit at speeds above
approximately 45 mph (70 km/h).
Queue AssistQueue Assist is an added ACC feature that is
linked to your vehicle's automatic transmis-
sion.
Queue Assist consists of the following func-
tions:
•Enhanced speed interval (including when
the vehicle is at a complete stop or is mov-
ing at speed below 18 mph (30 km/h))
•Automatic standby mode when ACC
changes target vehicles
•No automatic braking when at a standstill
•The parking brake is applied automatically

Please note that the lowest speed that can be
set is 18 mph (30 km/h), although ACC can
maintain a set speed/distance to a vehicle
ahead down to a standstill. Queue Assist con-
sists of the following features:
Enhanced speed interval
NOTE
The driver's door must be closed and the
driver's seat belt must be fastened before
ACC can be put in active mode. If the driv-
er's seat belt is taken off or if the driver's
door is opened, ACC will return to standby
mode.
Your vehicle can maintain the set time interval
to the vehicle ahead at any permissible speed,
including a complete stop.
In order to activate ACC at speeds below
18 mph (30 km/h):
•The vehicle ahead must be within a rea-
sonable distance (not farther away than
approx. 100 ft/30 meters)
•The lowest speed that can be selected is
18 mph (30 km/h), although ACC will also
help maintain the set time interval to the
vehicle ahead at lower speeds, including a
complete stop.During short stops (less than approximately
3 seconds) in slow-moving traffic, your vehicle
will begin moving again automatically as soon
as the vehicle ahead begins to move.
If it takes more than 3 seconds for the vehicle
ahead to begin moving, ACC will be automati-
cally go into standby mode.
The driver will then have to reactivate ACC in
one of the following ways:
•By pressing
•By accelerating up to at least 3 mph
(4 km/h). ACC will then resume following
the vehicle ahead.
Your vehicle will then resume following the
vehicle ahead at the set time interval.
NOTE
ACC can remain active and keep your vehi-
cle at a standstill for up to 4 minutes. After
4 minutes have elapsed, the parking brake
will be engaged and ACC will go into
standby mode.
To reactivate ACC, the driver must release
the parking brake (see page 125).
Automatic standby mode when ACC
changes target vehicles
If the vehicle ahead turns suddenly, there may be
a stationary vehicle ahead
The following only applies at speeds below
approximately 18 mph (30 km/h):
If ACC changes target vehicles (the vehicle that
the radar sensor has detected) from a moving
vehicle to a stationary one, the system will
apply the brakes in your vehicle.
WARNING
At speeds above 18 mph (30 km/h), ACC
will not react to a stationary vehicle and
apply the brakes but will instead accelerate
to the previously set speed. The driver must
actively apply the brakes to stop the vehicle.
ACC disengages and goes into standby mode

Collision warning with Full Auto-brake and Pedestrian Detection*
04
* Option/accessory, for more information, see Introduction.157 Introduction
Collision Warning with Full Auto-brake and
Pedestrian Detection is designed to assist the
driver if there is a risk of a collision with a
pedestrian, a vehicle ahead that is at a stand-
still or one that is moving in the same direction
as your vehicle.
Collision Warning consists of the following
three functions:
•Collision Warning warns the driver of a
potential collision situation.
•Brake Support helps the driver brake effi-
ciently in a critical situation.
•Auto-brake brakes the vehicle automati-
cally if a collision with a pedestrian or
another vehicle cannot be avoided and the
driver does not apply the brakes in time or
steer around the person/vehicle. Auto-
brake can help prevent a collision or
reduce the speed at which a collision
occurs.
Since Collision Warning with Full Auto-brake
and Pedestrian Detection is activated in cir-
cumstances where the driver should have
begun braking much sooner, the system will
not be able to assist the driver in all situations.
This system is designed to activate as late as
possible to help avoid unnecessary interven-
tion.The system should not be used in such a way
that the driver changes his/her way of operat-
ing the vehicle. If the driver relies entirely on the
system, the chances of an accident eventually
occurring increase considerably.
The Collision Warning and City Safety™ sys-
tems supplement each other. See page 151 for
detailed information about City Safety™.
WARNING
No automatic system can be guaranteed to
function 100% correctly in all situations. For
that reason, never test the Auto-brake sys-
tem by driving toward a person or object.
This could result in serious injury or death.
WARNING
•Collision Warning does not work in all
driving, traffic, weather and road condi-
tions. It does not react to vehicles not
traveling in the same direction as your
vehicle.
•Collision Warning does not react to ani-
mals.
•Warnings are only provided when the
risk of collision is high. The "Function"
section provides information about lim-
itations that the driver must be aware of
before using Collision Warning.
•Collision Warning will not provide a
warning or brake the vehicle for pedes-
trians at speeds above 50 mph
(80 km/h).

a relatively large area behind the vehicle is hid-
den and objects there may not be detected
until they are very near the vehicle.
NOTE
Bicycle carriers or other accessories moun-
ted on the trunk may obstruct the camera's
field of view.
Keep in mind
•Keep the camera's lens free of dirt, ice and
snow. Remove ice and snow carefully to
avoid scratching the lens.
•Clean the lens regularly with warm water
and a suitable car washing detergent.
