ble w
ith a torque wrench ⇒ page 307. Note
If the vehicle is fitted with a tyre monitoring system, this should be “reprog-
rammed” if nec
essary whenever a tyre is changed ⇒ page 223.Safety First Operating instructions Practical tips Technical Data

● V
ehicle tools ⇒ page 320 WARNING
A faulty vehicle in traffic represents a risk of accident for the driver and
for other r o
ad users.
● Stop the vehicle safely as soon as possible. Park the vehicle a safe
dist
ance from surrounding traffic to lock all the doors in case of an emer-
gency. Turn on the hazard warning lights to warn other road users.
● Never leave children or disabled people alone in the vehicle if the
doors ar
e to be locked. In case of an emergency, passengers will be trap-
ped inside the vehicle. Individuals locked in the vehicle can be exposed
to very high or very low temperatures. Protecting yourself and securing the vehicle Fig. 186 In the centre of

Switch for hazard warn-
ing lights.
Always fulfil legal requirements for securing a broken down vehicle. In a
number of cou
ntries it is now obligatory, for example, to turn on the hazard
warning lights and use a reflective safety vest ⇒ page 314.
When being towed with the hazard warning lights on, a change in direction
or traffic lane can be indicated as usual using the turn indicator lever. The
hazard lights will be interrupted temporarily.

WARNING
The components of the exhaust system reach very high temperatures.
This c
ould cause a fire and considerable damage.
● Always park your vehicle so that no part of the exhaust system can
come in cont
act with flammable materials (such as dried grass or fuel). Note
● The vehicle battery will discharge and run down if the hazard warning
lights r
emain on for too much time (even with the ignition turned off).
● For some vehicles, the brake lights will blink when braking suddenly at
speeds
of approximately 80 km/h to warn vehicles behind. If braking con-

If and when
Fuses
Introduction Due to the constant update of vehicles, fuse assignments depending on
equipment and the u
se of
the same fuse for various electrical components,
at the time of printing this manual it is not possible to provide an up-to-date
summary of the electrical components fuse positions. For detailed informa-
tion about the fuse positions, please consult a Technical Service.
In general, a fuse can be assigned to various electrical components. Like-
wise, an electrical component can be protected by several fuses.
Only replace fuses when the cause of the problem has been solved. If a
newly inserted fuse blows after a short time, you must have the electrical
system checked by a qualified dealership as soon as possible.
Additional information and warnings:
● Working in the engine compartment ⇒ page 275WARNING
The high voltages in the electrical system can give serious electrical
shock s, c
ausing burns and even death!
● Never touch the electrical wiring of the ignition system.
● Take care not to cause short circuits in the electrical system. WARNING
Using unsuitable fuses, repairing fuses or bridging a current circuit with-
out f u
ses can cause a fire and serious injury.
● Never use a fuse with a higher value. Only replace fuses with a fuse of
the same amperag
e (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar. CAUTION
● To avoid damage to the vehicles electric system, before replacing a fuse
t urn off
the ignition, the lights and all electrical elements and remove the
keys from the ignition.
● If you replace a fuse with higher-rating fuse, you could cause damage to
another part
of the electrical system.
● Protect the fuse boxes when open to avoid the entry of dust or humidity.
Dirt and humidity
inside fuse boxes can cause damage to the electrical sys-
tem. Note
● One single consumer could have more than one fuse.
● Sev er
al consumers could run over one single fuse.
