The alarm system briefly indicates unauthorized
entry or tampering by means of:
>An acoustic alarm
> Switching on the haza rd warning flashers
Arming and disarming
Whenever the car is locked or unlocked, the
alarm system is armed or disarmed.
Even when the alarm syst em is armed, you can
open the liftgate by means of the button
on the remote control.
When you subsequently close the liftgate it is
again locked and monitored.
In certain market-specific versions,
unlocking via the door lock triggers the
alarm. <
Panic mode*
You can activate the alarm system if you find
yourself in a dangerous situation.
Press the button for at least two seconds.
Switching off the alarm:
Press any button.
Switching off an alarm
>Unlock the car with the remote control.
> Insert the key fully into the ignition lock.
> In cars with Comfort Access
*, press the but-
ton on the door lock.
Display on the revolution counter
When the system is armed, all LEDs pulse. After
approx. 16 minutes one LED flashes. >
LEDs pulse or LED flashes: system is armed.
> One LED flashes at short intervals:
A door, the hood or the liftgate is not prop-
erly closed. Even if these are not closed fully,
the remaining items ar e deadlocked and the
LEDs pulse after approx. 10 seconds for
approx. 16 minutes. Afterwards, one LED
flashes.
The interior movement detector is not acti-
vated.
> LEDs go out after the vehicle is unlocked:
No attempt was made to tamper with the
car.
> LEDs flash after unlocking until the key is
inserted in the ignition, but for no longer
than approx. 5 minutes: an attempt was
made to tamper with the car.
Tilt alarm sensor
The vehicle's inclination is monitored. The alarm
is triggered, for instance , if an attempt is made
to steal the car's wheels or tow it away.
Interior movement detector
Before the interior movement detector can
operate correctly, the windows and glass roof
must be closed.
Avoiding false alarms
The tilt alarm sensor and the interior movement
detector can be switched off together.
This prevents false alarms, e.g. in the following
situations:
> In duplex garages
> When being transported on car-carrying
trains, ferries or trailers
> If pets are to remain inside the car

Technology for driving comfort and
safety
Park Distance Control
PDC*
The concept
PDC assists you with parking in reverse. Acoustic
signals and a visual indicator
warn you of the
presence of an object behind the 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 rear corner sensors, or approx.
5 ft/1.50 m from the rear center sensors. PDC is
a parking aid that can indicate objects when
they are approached slowly, as is usually the
case when parking. Avoid approaching an
object at high speed; ot herwise, physical cir-
cumstances may lead to the system warning
being issued too late. <
Automatic mode
With the engine running or the ignition switched
on, the system is activated automatically after
approx. 1 second when you engage reverse
gear or move the automatic transmission selec-
tor lever to position R. Wait this short period
before driving.
Acoustic signals
As the distance between vehicle and object
decreases, the intervals between the tones
become shorter. If the distance to the nearest
object falls to below roughly 1 ft/30 cm, then a
continuous tone sounds.
If the distance remains co nstant, e.g. when driv-
ing parallel to a wall, th e acoustic signal stops
after approx. 3 seconds.
Malfunction
Indicator lamp lights up: PDC has failed.
A message appears on the Control Dis-
play. 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 operate effectively. When
using a high-pressure cleaner, do not direct the
jet toward the sensors for lengthy periods and
only spray from a distance of at least 4 in/10 cm.
PDC with visual warning
To have the system show distances to objects on
the Control Display. The contours of distant
objects are shown on the Control Display even
before the acoustic sign al sounds. The display
appears on the Control Display as soon as the
transmission is shifted into reverse or the selec-
tor lever is moved into the R position.
System limitations
Even with PDC, final responsibility for esti-
mating the distance between the vehicle
and any obstructions always remains with the
driver. Sensors, too, have blind spots in which
objects cannot be dete cted. Moreover, ultra-
sonic detection can reach its physical limits with
objects such as trailer tow bars and couplings,
thin and wedge-shaped objects, etc. Low
objects already indicated, such as curbs, may
enter the sensors' blind spots before or after a
continuous audible signal is given. Higher, pro-
truding objects, such as wall ledges, may not be
detectable. Therefore, always drive cautiously;
otherwise, there is a risk of personal injury or
property damage. Loud sound sources outside
or inside the car can drown out the PDC signal. <

DRIVING TIPSThings to remember when driving
102
Flat load floor*
The maximum load of the flat load floor is
165 lbs./75 kg. Do not exceed a maximum
permissible load of 55 lbs./25 kg for the storage
compartment beneath the flat load floor; other-
wise, damage can occur. <
Raise the flat load floor and fold it up toward the
front, arrow.
Removing
1. Fold up the flat load floor.
2. Pull the load floor back slightly.
3. Then take it out toward the top.
Determining cargo limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, damage to
the vehicle and unstable driving conditions
may result. <
2. Determine the combined weight of the
driver and passengers that will be riding in
your vehicle. 3.
Subtract the combined weight of the driver
and passengers from XXX pounds or
YYY kilograms.
4. The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
1,400 lbs. and there will be four 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
650 lbs.:
1,400 lbs. minus 750 lbs. = 650 lbs.
5. Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6. If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
Load
The permissible load is the sum of the occu-
pants' weights and the we ight of the cargo. The
greater the weight of the occupants, the less
cargo/luggage can be transported.
