Driver assistance systems
The driver should then not reverse any fur-
ther.
The warning tone volume decreases by 30%
3 seconds after it is triggered if the detected
obstacle stays at a constant distance from
the vehicle.
Provided that it is not in continuous mode,
the tone on the parking aid system stops
when it detects a wall parallel to the vehicle.
Trailer towing
For vehicles factory-fitted with a towing bar,
the parking aid system will not be activated
by the engagement of the reverse gear when
pulling a trailer, as the trailer's electric con-
nector will be plugged into the vehicle.
Possible faults
If a continuous, sharp beep sounds for a few
seconds, there is a fault in the parking aid
system.
If the fault continues until the ignition is
turned off, the audible warning of the fault
will not be emitted every time the system is
reactivated (by engaging the reverse gear or
pressing the button). Thus, the system
ready indication will not sound either. Have
the fault repaired by technical services as
soon as possible.
If there is no ready signal or no acoustic
warning signal, then the parking aid loud- speaker is faulty and may not warn of obsta-
cles. To ensure that the system works proper-
ly, the sensors must be kept clean and free of
ice and snow.
CAUTION
● Please note that low obstacles detected by
the system may no longer be registered by
the sensors as the car moves closer, so the
system will not give any further warning. Cer-
tain kinds of obstacles, such as wire fences,
chains, thin posts or trailer draw bars, high
kerbs or painted railings, etc., may not al-
ways be detected by the system, so there is a
risk of damaging the vehicle in such cases.
● In some cases, obstacles with uniform
edges and bumps may not be detected imme-
diately by the system due to their geometry.
Take special care with this type of obstacle
(corners, rectangular objects, etc.), as they
can cause damage to the vehicle.
● Be especially careful when manoeuvring in-
to a corner between two perpendicular walls.
Pay special attention to the side distance
from the wall using the mirrors.
● The parking aid system does not replace
use of the mirrors for manoeuvres.
● External ultra-sonic sources (e.g. pneumat-
ic drills, construction machinery or other ve-
hicles equipped with PND) may interfere with
the operation of the system.
● Periodic cleaning of the sensors, take care
not to damage or scratch them. When clean-
ing with high pressure washers or steam cleaners, the sensors should be sprayed for
only a very short period and from a distance
of more than 10 cm.
●
If the licence plate (especially the front
one) is bent in such a way that it noticeably
juts out from the bumper, false alarms may
sound for the area in front of the vehicle. Front parking aid with navigator view

The essentials
Checking and refilling levels
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
●
If any work has to be performed when the
engine is started or with the engine running,
there is an additional, potentially fatal, safety
risk from the rotating parts, such as the drive
belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
engine parts. Danger of death. Before
starting any work remove jewellery, tie
back and cover hair, and wear tight-fit-
ting clothes.
– Never accelerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if the
handbrake is applied. Danger of death.
● If work has to be carried out on the fuel
system or on electrical components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. The vehicle must be
unlocked when this is done, otherwise
the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand. CAUTION
When topping up service fluids, make sure
not to mistake them. Using the wrong fluids
could cause serious malfunctions and engine
damage! For the sake of the environment
Service fluids leaks are harmful to the envi-
ronment. For this reason you should make
regular checks on the ground underneath
your vehicle. If you find spots of oil or other
fluids, have your vehicle inspected in a speci-
alised workshop. Opening the bonnet
Read the additional information carefully
››› page 10
The bonnet is released from inside the vehi-
cle.
Before opening the bonnet ensure that the
windscreen wipers are in rest position. WARNING
Hot coolant can scald!
● Never open the bonnet if you see steam,
smoke or coolant escaping from the engine
compartment. ●
Wait until no more steam, smoke or coolant
is emitted from the bonnet, then carefully
open the bonnet.
● When working in the engine compartment,
always observe the safety warnings
››› page 166. Closing the bonnet
–
Slightly lift the bonnet.
– Release the bonnet stay and replace it in its
support.
– At a height of approximately 30 cm let it fall
so it locks.
If the bonnet does not close, do not press
downwards. Open it again and let it fall as
mentioned above. WARNING
If the bonnet is not closed properly, it could
open while you are driving and completely
obscure your view of the road. Risk of acci-
dent.
● After closing the bonnet, always check that
it is properly secured. The bonnet must be
flush with the surrounding body panels.
● If you notice that the bonnet latch is not se-
cured when the vehicle is moving, stop the
vehicle immediately and close the bonnet
properly. Risk of accident. 167Technical specifications

Checking and refilling levels
●
Fires, sparks, open flames and smoking are
prohibited. When handling cables and electri-
cal equipment, avoid causing sparks and
electrostatic charge. Never short the battery
terminals. High-energy sparks can cause in-
jury.
● A highly explosive mixture of gases is re-
leased when the battery is under charge. The
batteries should be charged in a well-ventila-
ted room only.
● Keep children away from acid and batteries.
● Before working on the electrical system,
you must switch off the engine, the ignition
and all electrical devices. The negative cable
on the battery must be disconnected. When a
light bulb is changed, you need only switch
off the light.
● Deactivate the anti-theft alarm by unlock-
ing the vehicle before you disconnect the bat-
tery! The alarm will otherwise be triggered.
● When disconnecting the battery from the
vehicle on-board network, disconnect first
the negative cable and then the positive ca-
ble.
● Switch off all electrical devices before re-
connecting the battery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire.
● Never charge a frozen battery, or one which
has thawed. This could result in explosions
and chemical burns. Always replace a battery
which has frozen. A flat battery can also
freeze at temperatures close to 0 °C (+32 °F). ●
Ensure that the vent hose is always connec-
ted to the battery.
● Never use a defective battery. This could
cause an explosion. Replace a damaged bat-
tery immediately.
● For vehicles with the battery in the luggage
compartment: Check that the battery gas
ventilation hose is securely attached. CAUTION
● Never disconnect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components.
● Do not expose the battery to direct sunlight
over a long period of time, as the intense ul-
traviolet radiation can damage the battery
housing.
● If the vehicle is left standing in cold condi-
tions for a long period, protect the battery
from “freezing”. If it freezes it will be dam-
aged. Checking the electrolyte level
The electrolyte level should be checked regu-
larly in high-mileage vehicles, in hot coun-
tries and in older batteries.
– Open the bonnet and open the battery cov-
er at the front ››› in Safety instructions
on working in the engine compartment on
page 166
›
›› in Warnings on handlingthe battery on page 174. For vehicles with
the battery under the spare wheel, open
the rear lid and lift the floor covering. The
battery is located next to the spare wheel.
– Check the colour display in the "magic eye"
on the top of the battery.
– If there are air bubbles in the window, tap
the window gently until they disperse.
The position of the battery is shown in the
corresponding engine compartment diagram
››› page 168 . The location of the battery in
the lug g
age compartment can be seen in
››› Fig. 152.
The “magic
eye” indicator, located on the top
of the battery changes colour, depending on
the charge state and electrolyte level of the
battery.
There are two different colours:
● Black: correct charge status.
● Transparent/clear yellow: the battery must
be replaced. Contact a specialised workshop.
Charging and changing the vehicle
battery The battery is maintenance-free and is
checked during the inspection service. All
work on the vehicle battery requires special-
ist knowledge.
