First look at the coolant temperature gauge. If the needle is in the normal
range, top up with coolant at the earliest opportunity ⇒
.
WARNING
•
If your vehicle is immobilised for any technical reasons, move it to a
safe distance from traffic. Turn off the engine, turn on the hazard lights and
place the warning triangle.
•
Never open the bonnet if you can see or hear steam or coolant escaping
from the engine compartment. Risk of scalding. Wait until you can no
longer see or hear escaping steam or coolant.
•
The engine compartment of any motor vehicle is a dangerous area!
Before carrying out any work in the engine compartment, switch off the
engine and allow it to cool down. Always note the corresponding warnings
⇒ page 193.
Rear fog light

This warning lamp lights up when the rear fog light is switched on
. Further
information ⇒page 109.
Turn signals
 
The warning lamp flashes when the turn signals are in oper-
ation.Depending on which turn signal is operated, either the left
 or right
 indi-
cator lamp flashes. Both warning lamps wi ll flash at the same time when the
hazard warning lights are switched on.
If one turn signal fails, the warning lamp will start flashing twice as fast. Further information on the turn signals
⇒page 113.
Trailer turn signals

This warning lamp also flashe s when the turn signals are
operated while towing a caravan or trailer.The warning lamp
 flashes when the turn signals are operated, provided a
trailer is correctly attached and connected to the vehicle.
The warning lamp will not flash if one of the turn signals on the trailer fails.

WARNING
The main beam can dazzle other drivers. Risk of accident! Never use the
main beam headlights or the headlight flasher if they could dazzle other
drivers.
Note
•
The turn signals only work when the ignition is switched on. The corre-
sponding warning lamp
 or  flashes in the combi-instrument. The
warning lamp
 flashes when the turn signals are operated, provided a
trailer is correctly attached and connected to the vehicle. If a turn signal bulb
is defective, the warning lamp flashes at double speed. If the trailer turn
signal bulbs are damaged, warning lamp
 does not light up. You should
have the bulb replaced.
•
The main beam headlights can only be switched on if the dipped beam
headlights are already on. The warning lamp
 then comes on in the combi-
instrument.
•
The headlight flasher comes on for as long as you pull the lever – even if
no other lights are switched on. The warning lamp
 then comes on in the
combi-instrument.
•
When the parking lights are switched on, the headlight and the rear light
on the corresponding side of the vehicle light up. The parking lights will only
work if the key is removed from the ignition. If the lights are switched on, a
buzzer gives an audible warning while the driver door is open.
•
If the turn signal lever is left on after the key has been taken out of the
ignition lock, an acoustic signal sounds when the driver door is opened. This
is a reminder to switch off the turn signal, unless of course you wish to leave
the parking light on.
Interior lightsFront interior light The switch ⇒fig. 77 is used to select the following positions:

Checking and refilling levels
208charge. Never short the battery terminals. High-energy sparks can cause
injury.•
A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated 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 consumers. 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 unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.
•
When disconnecting the battery from the vehicle electrical system,
disconnect first the negative cable and then the positive cable.
•
Switch off all electrical consumers before reconnecting 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 freeze at temperatures around 0
°C.
•
Ensure that the vent hose is always connected to the battery.
•
Never use a defective battery. This may be fatally explosive. Replace a
damaged battery immediately.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 compo-
nents.
•
Do not expose the battery to direct sunlight over a long period of time, as
the intense ultraviolet radiation can damage the battery housing.
•
If the vehicle is left standing in cold conditions for a long period, protect
the battery from frost. If it “freezes” it will be damaged.
Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries.– Open the bonnet and open the battery cover at the front ⇒ in
“Safety instructions on working in the engine compartment” on
page 193 ⇒ in “Warnings on handling the battery” on
page 207.
– 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 show n in the corresponding engine compart-
ment diagram ⇒page 252.
The round window (“magic eye”) on the top of the battery changes colour,
depending on the charge level and electrolyte level of the battery.
If the colour in the window is colourless or bright yellow, the electrolyte level
of the battery is too low. Have the battery checked by a qualified workshop.
The colours green and black are used by the workshops for diagnostic
purposes.

Bulb changeGeneral notesBefore changing any bulb first turn off the equipment concerned.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a
reduction in the bulb life and condensation on the mirror surface, thus
reducing efficiency.
A bulb should only be replaced by one of the same type. The type is inscribed
on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the bulbs that most affect road safety should have spares in the
vehicle.

Note
•
Due to the difficulty in accessing the lamps, these must be changed by an
Authorised Service Centre. However, the following is a description of how to
change the bulbs except for the fog lights and interior bulbs.
19)For these type of headlights, the bulbs must be changed by an Authorised Service
Centre, given that complex elements of the vehicle must be removed and that the au-
tomatic control system must be reset.20)Xenon bulbs discharge emit 2.5 times as much light flux and have a useful life five
times greater than halogen bulbs.
21)Electronically controlled single filament bulb for Stop/Side bulbs. If the bulb blows
it will not work or Stop position.
