Press the window shut to close it.Make sure that the corners of any pointed
or sharp-edged cargo are padded if they
could bump against the rear window while the
vehicle is in motion, otherwise the heating ele-
ments of the rear window could be damaged. <
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage com-
partment lid/tailgate is opened
> To movements inside the vehicle: Interior
motion sensor, refer to page 33
> When the car's inclination changes, for
instance if an attempt is made to jack it up
and steal the wheels or to raise it prior to
towing away
> When there is an interruption in the power
supply from the battery
The alarm system signals unauthorized entry
attempts for a short time by means of:
> An acoustic alarm
> Switching on the haza rd warning flashers
> Flashing the high beams
Arming and disarming
When you lock or unlock the vehicle, either with
the remote control or at the door lock, the alarm
system is armed or disarmed at the same time.
You can open the luggage compartment lid/tail-
gate even when the alarm system is armed, by
pressing the button on the remote control,
refer to page 28. The lid is locked and moni-
tored again as soon as you close it.
Panic mode*
You can trigger the alarm system if you find
yourself in a dangerous situation:
Press the button for at least three seconds.
To switch off the alarm: press any button.
Switching off an alarm
> Unlock the car with the remote control, refer
to page 27.
> Insert the remote control all the way into the
ignition lock.
Indicator lamp displays
>The indicator lamp un der the inside rear-
view mirror flashes continuously: the sys-
tem is armed.
> The indicator lamp flashes after locking:
doors, hood, luggage compartment lid/tail-
gate or rear window are not properly closed.
Even if you do not close the alerted area, the
system begins to monitor the remaining
areas, and the indicator lamp flashes con-
tinuously after approx. 10 seconds. The
interior motion sensor and the tilt alarm
sensor are not activated.
> The indicator lamp goes out after unlocking:
your vehicle has not been disturbed while
you were away.
> If the indicator lamp flashes after unlocking
until the remote control is inserted in the
ignition, but for no longer than approx.
5 minutes: your vehicle has been disturbed
while you were away.
Tilt alarm sensor
The tilt of the vehicle is monitored. The alarm
system reacts, e.g. to attempts to steal a wheel
or tow the vehicle.
Interior motion sensor
In order for the interior motion sensor to func-
tion properly, the windows and glass roof must
be completely closed
*.

Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following
situations:
>In duplex garages
> During transport on car-carrying trains,
boats/ships or on a trailer
> When animals are to remain in the vehicle
Switching off tilt alarm sensor and
interior motion sensor
Press the button on the remote control
again as soon as the vehicle is locked.
The indicator lamp light s up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are switched off until
the next time the vehicle is unlocked and subse-
quently locked again.
Convenient access*
Convenient access enables you to enter your
vehicle without needing to hold the remote con-
trol in your hand. All you need to do is wear the
remote control close to your body, e.g. in your
jacket pocket. The vehicle detects the corre-
sponding remote control within the immediate
vicinity or in the passenger compartment.
Convenient access supports the following
functions:
> Unlocking/locking the vehicle
> Unlocking the luggage compartment lid/
tailgate separately
> Engine starting
> Convenient closure
Functional requirement
>The vehicle or the luggage compartment
lid/tailgate can only be locked when the
vehicle detects that th e remote control cur-
rently in use is ou tside of the vehicle.
> The vehicle cannot be locked or unlocked
again until after approx. 2 seconds. >
The engine can only be started when the
vehicle detects that th e remote control cur-
rently in use is inside the vehicle.
Comparison to the standard remote
control
In general, there is no difference between using
convenient access or pressing the buttons on
the remote control to carry out the functions
mentioned above. You should therefore first
familiarize yourself with the instructions on
opening and closing starting on page 26.
Special features regarding the use of conve-
nient access are described below. If you notice a brief delay while opening or
closing windows or the glass roof/pan-
orama glass roof, the system is checking
whether a remote control is inside the vehicle.
Please repeat the opening or closing proce-
dure, if necessary. <
Unlocking
Grasp the handle on the driver's or front pas-
senger's door completely, arrow 1. This corre-
sponds to pressing the button.
Locking
Touch the surface, arrow 2, with your finger for
approx. 1 second. This corresponds to pressing
the button.
To preserve the battery, please make
sure that the ignition and all electrical
consumers are switched off before locking the
vehicle. <

Warning lamps
The indicator 2 flashes in red; a
signal sounds.
The system indicates that you
must brake and/or maneuver the
vehicle yourself. Active cruise con-
trol cannot automatically restore the distance to
the vehicle ahead.
This indicator does not release you from your
responsibility to adapt your desired speed and
driving style to prevailing driving conditions.
The indicator 2 flashes in yellow.
The prerequisites for operating
active cruise control are not met,
e.g. as a result of ABS or DSC
interventions. Active cruise control
is deactivated. You can re activate the system, if
desired, by tapping or pulling the lever when
road and traffic conditions permit. It is not pos-
sible to resume a stored speed.
Radar sensor
The sensor's ability to detect vehicles ahead
may be restricted as a result of heavy rain, dirt,
snow or ice. If necessary, clean the radar sensor
located in the front bump er, see arrow. Be sure
to use particular care when removing any layers
of snow or ice from the sensor.

When the radar sensor is not properly posi-
tioned, active cruise control cannot be activated
at all.Malfunction
The warning lamp comes on when
the system has failed. A message
appears on the Control Display. You
can find more information starting on page 75.
System limitations
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, as for example, at a traffic light or a
parked vehicle. Also, the system does not react
to oncoming traffic, pe destrians or other types
of potential traffic such as a rider on horseback.
It is also possible th at the system may not
detect smaller moving objects such as motor-
cycles or bicycles. Be especially alert when
encountering any of these situations as the sys-
tem will neither automatically brake, nor provide
a warning to you. Also, be aware that every
decrease in the distance setting allows your
vehicle to come closer to a vehicle in front of
you and requires a heightened amount of alert-
ness. <
Active cruise control is not and must not
be used as a collision avoidance/warning
system. <
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds
up or the lane ahead becomes clear, then your
vehicle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating. Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp. <
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brak es if necessary.
While active cruise control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, e.g.
when you reduce your desired speed sharply.
The system cannot stop your vehicle. It uses
only a portion of brakin g system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: when you approach a vehicle
traveling at a much lower speed than your own
speed such as approachin g a toll booth or when
a much slower vehicle cuts in front of you at
close range. <
Active cruise control ca n only decelerate the
vehicle to approx. 20 mph or 30 km/h.

Technology for driving comfort and safety
Park Distance Control PDC*
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals and a visual
indicator
warn you of the presence of an object
behind your vehicle. To measure the distance,
there are four ultrasonic sensors in either
bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not
sound until an object is approx. 24 in/60 cm
from the corner sensors, or approx. 5 ft/1.50 m
from the center sensors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually th e case when parking.
Avoid approaching an object at high speed, oth-
erwise physical circumstances may lead to the
system warning being issued too late. <
Switching on automatically
With the engine running or the ignition switched
on, the system is activated after approx. 1 sec-
ond when you engage reverse gear or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 165 ft/50 m of driving or above
approx. 20 mph/approx. 30 km/h, the system
switches off and the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. As the dis-
tance between vehicle an d object decreases,
the intervals betwee n the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx.
3seconds >
if you remain in front of an object that has
been detected by only one of the corner
sensors
> if you are driving parallel to a wall.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning. A message appears on the
Control Display. Have the system checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to op erate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 4 in/10 cm.
PDC with visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis-
play before a signal to ne sounds. The display
appears on the Control Di splay as soon as PDC
is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind sp ot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with traile r towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or af ter a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously, otherwise there is a risk of personal
injury or property damage.

and increase the air volume.<
Automatic recirculated-air control
AUC/Recirculated-air mode
Switch on the desired operating
mode by pressing this button
repeatedly:
> LED off: outside air flows in continuously.
> Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
> Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. The system then recirculates the
air currently within the vehicle.
If condensation star ts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasi ng the air flow rate as
required.
The recirculated-air mode should not be used
over an extended period of time, otherwise the air quality inside the ca
r will deteriorate contin-
uously. <
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
> Up to 15 minutes after the engine has been
switched off
> While the engine is at operating tempera-
ture
> As long as battery voltage is sufficient
> At an outside temperature below 77 7/
25 6
The LED is lit when the function is on.
As of radio readiness, you can set the interior
temperature, the air flow rate and the air distri-
bution.
Defrosting window s and removing
condensation
Quickly removes ice and conden-
sation from the windshield and
front side windows.
Switch on the cooling function as well.
Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before reheating it as required,
according to the temp erature setting. This
function is only availa ble while the engine is
running.
The cooling function helps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weathe r, the windshield may
fog over briefly when the engine is started.
Pressing the AUTO button automatically
switches on the cooling function.
