Note
•
If, after the alarm goes off, access is gained to a second secured zone
(e.g. the tailgate is opened after a door has been opened), the warning signal
is triggered again.
•
Vehicle monitoring remains active even if the battery is disconnected or
not working for any reason.
•
The alarm is triggered immediately if one of the battery cables is discon-
nected while the alarm system is active.
Volumetric sensor*
Monitoring or control function incorporated in the anti-theft
alarm*, that detects unauthorized vehicle entry using ultra-
sound.The system consists of 3 sensors, 2 emitters and a receptor.
Activation
– It is automatically turned on with the anti-theft alarm, when the
vehicle is locked mechanically with the key and when the button on the remote control is used.
Deactivation
– Press the button on the remote control twice. Only the volu- metric sensor is deactivated. The alarm system remains acti-
vated.
WARNING
•
The “safe” security system remains deactivated if the volumetric
sensor is deactivated.
•
For those vehicles in which a separate sunblind is fitted in the
passenger compartment, the alarm will not function correctly due to inter-
ference with the sensor.Note
•
If the alarm has been triggered by the volumetric sensor, this will be indi-
cated by a flashing of the indicator on th e driver's door. This flashing will be
different to that for an activated alarm.

Driving
158Always apply the handbrake firmly. This prevents you driving with the hand-
brake applied ⇒.
The handbrake warning lamp
 lights up when the handbrake is applied
and the ignition switched on. The warning lamp goes out when the hand-
brake is released.
If you drive faster than 6 km/h with the handbrake on, the following
message* will appear in the combi-instrument display: HANDBRAKE ON.
Also, an audible warning is given.
WARNING
•
Never use the handbrake to slow down the vehicle when it is in motion.
The braking distance is considerably longer, as braking is only applied to
the rear wheels. Ri sk of accident!
•
If it is only partially released this will cause overheating of the rear
brakes, which can impair the function of the brake system and could lead
to an accident. This also causes premature wear on the rear brake
pads/linings.Caution
Always apply the handbrake before you leave the vehicle. The first gear
should also be selected.Parking
The handbrake should always be firmly applied when the
vehicle is parked.Always note the following points when parking the vehicle:
– Use the foot brake to stop the vehicle. –Apply the handbrake.
– The first gear should also be selected.
– Switch off the engine and remove the key from the ignition lock.
Turn the steering wheel slightly to engage the steering lock.
– Always take you car keys with you when you leave the vehicle ⇒ .
Additional notes on parking the vehicle on gradients:
Turn the steering wheel so that the vehicle would roll against the kerb if it did
start to roll.•
If the vehicle is facing downhill, turn the front wheels so that they point
towards the kerb .
•
If the vehicle is facing uphill , turn the front wheels so that they point away
from the kerb .
•
Secure the vehicle as normal by applying the handbrake firmly and
selecting first gear.
WARNING
•
Take measures to reduce the risk of injury when you leave your vehicle
unattended.
•
Never park where the hot exhaust system could ignite inflammable
materials, such as dry grass, low bushes, spilt fuel etc.
•
Never allow vehicle occupants to remain in the vehicle when it is
locked. They would be unable to open the vehicle from the inside, and
could become trapped in the vehicle in an emergency. In the event of an
emergency, locked doors will delay assistance to occupants.
•
Never leave children unsupervised in the vehicle. They could set the
vehicle in motion, for example, by releasing the handbrake or the gear
lever / selector lever.

Trailer towingWhat do you need to bear in mind when towing a trailer?Your vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If the car is supplied with a
factory-fitted towing bracket it will already have
the necessary technical modifications and meet the statutory requirements
for towing a trailer. For the after-market fitting of a trailer towing bracket see
⇒ page 188.
Connectors
Your vehicle is fitted with a 12-pin co nnector for the electrical connection
between the trailer and the vehicle.
If the trailer has a 7-pin plug you will need to use an adapter cable. This is
available from any Technical Service.
Trailer weight / draw bar loading
Never exceed the authorised towing limit. If you do not load the trailer up to
the maximum permitted trailer weight , you can then climb correspondingly
steeper gradients.
The maximum trailer weights listed are only applicable for altitudes up to
1,000 m above sea level. With increasing altitude the engine power and
therefore the vehicle's climbing ability are impaired because of the reduced
air density. The maximum trailer weight has to be reduced accordingly. The weight of the vehicle and trailer combination must be reduced by 10% for
every further 1,000 m (or part thereof).
The gross combination weight is the
actual weight of the laden vehicle plus the actual weight of the laden trailer.
Where possible, operate the trailer with the maximum permitted draw bar
weight on the ball joint of the towing bracket, but do not exceed the specified
limit.
The figures for trailer weights and draw bar weights that are given on the
data plate of the towing bracket are for certification purposes only. The
correct figures for your specific model, which may be lower than these figures
for the towing bracket, are given in the registration documents ⇒Section
“Technical data”.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them
moving.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the sticker
on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres in
accordance with the trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. Both exterior mirrors should be mounted on hinged extension
brackets. Adjust the mirrors to give sufficient vision to the rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents.

Note•
Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the
vehicle is used frequently for towing a trailer.
•
Find out whether special regulations apply to towing a trailer in your
country.
Ball coupling of towing bracket*Depending on the model version, the spherical head on the trailer hook may
be found in the tool box.
The ball coupling is provided with in structions on fitting and removing the
ball coupling of the towing bracket.
WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and causing
injury.
Note
•
By law, the ball coupling must be removed if a trailer is not being towed
and it obscures the number plate.
Driving tips
Driving with a trailer always requires extra care.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason it is advisable not to drive at the maximum permissible speed in
unfavourable road, weather or wind conditions. This applies especially when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of snaking . Never try to stop the “snaking” by increasing speed.
Always brake in good time. If the trailer has an overrun brake, apply the
brakes gently at first and then firmly. This will prevent the jerking that can be
caused by the trailer wheels locking. Sele ct a low gear in good time before
going down a steep descent. This enables you to use the engine braking to
slow down the vehicle.
Heating
When climbing long hills in hot weather with the engine running fast in a low
gear, you should monitor the coolant temperature gauge ⇒page 55.
Electronic Stabilisation Program*
Do not switch off the ESP* when towing a trailer. The ESP* makes it easier to
stabilise if the trailer starts to snake.
