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-
tinues, then the hazard warning lights will automatically be turned on at the
speed of less than approximately 10 km an hour. The brake lights remain lit.
Upon accelerating, the hazard warning lights will be automatically turned
off. Safety First Operating instructions Practical tips Technical Data

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.

If and when
Changing bulbs
Introduction Changing bulbs requires a certain amount of manual skill. If you are unsure,
SEA
T r
ecommends that you consult an qualified workshop or request assis-
tance from a specialist. In general, a specialist is required if other vehicle
components must be removed or if the discharge lamps must be replaced.
You should store spare light bulbs in the vehicle for safety-relevant lights.
Spare bulbs may be obtained from the Official dealers and workshops. In
some countries, it is a legal requirement to carry spare bulbs in the vehicle.
Driving with faults and blown bulbs on the vehicle exterior lighting is
against the law.
Additional bulb specifications
The specifications of some headlamp bulbs and bulbs for the tail lamps fit-
ted at the factory may be different to those of conventional bulbs. Bulb in-
formation is displayed on the bulb socket or on the bulb itself.
Additional information and warnings:
● Lights and visibility ⇒ page 95
● W
orking in the engine compartment ⇒ page 275
● V
ehicle tools ⇒ page 320
● F
uses ⇒ page 322 WARNING
If the road is not well-lit and the vehicle is not clearly visible to other
driver s, ther
e is a risk of accident. WARNING
Failure to replace bulbs correctly may cause serious accidents.
● Before carrying out any work in the engine compartment please read
and ob ser
ve the warnings ⇒ page 275. In any vehicle, the engine com-
partment is a hazardous area and could cause severe injury.
● Discharge lamps work with high-voltage and can cause serious or fa-
tal
injury if handled incorrectly.
● H7 and discharge lamps are highly pressurised and could explode
when being ch
anged.
● Only replace the bulbs concerned when they have cooled.
● Never replace bulbs alone if you are not familiar with the operations
neces
sary. If you are not sure about procedures then visit a Technical
Service to carry out the necessary work.
● Never touch the bulb glass directly. Fingerprints will be evaporated by
the heat of
the operating bulb thus “fogging” up the reflector.
● The headlamp frameworks in the engine compartment and the tail
lamps
contain sharp elements. Always protect your hands when chang-
ing bulbs. CAUTION
After changing a bulb, if the rubber covers and plastic caps are not replaced
corr ectly
on the headlamp framework, the electrical installation may be
damaged, especially if water is allowed to enter.
Indicator lights up Possible cause Solution
A vehicle exterior lighting
bu
l
b is not working. Replace the faulty bulb.

327
If and when
Several warning and control lamps should light up for a few seconds when
the ignition is sw
itched. This signals that the lamp is working properly. They
will switch off after a few seconds.
Checking the bulbs of a trailer
For vehicles with the factory fitted trailer system, certain trailer lights are al-
so controlled if the socket is correctly connected.
A fault on a trailer turn indicator is indicated on the instrument panel by the
indicator blinking twice as fast ( or ) ⇒ page 95.
● General fault of all indicators on one side.
● Fault in one tail light (on some models, also the registration light).
● Fault in two brake lights. WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or m a
y cause accidents and severe injuries.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible. CAUTION
Failure to heed the warning lamps and text messages when they appear
ma y
result in faults in the vehicle. Note
A fault in the LED on the tail lights will not be indicated. However, if the fault
affects al
l the LEDs then this will be indicated by the indicator . Information for replacing bulbs Checklist
To r
ep
lace a bulb, carry out the following operations always in the order giv-
en ⇒ :
Park the
vehicle a safe distance from traffic and on suitable ground.
Connect the electronic parking brake ⇒ page 183.
Turn the light switch to position 0 ⇒ page 95.
Move the gear lever into the neutral position ⇒ page 95.
Automatic gearbox: Move selector lever to position P ⇒ page 174.
Stop the engine and remove the key from the ignition ⇒ page 170.
Manual gearbox: Select a gear ⇒ page 174.
Wait until all of the passenger compartment lights are turned off
⇒ page 95.
Allow the corresponding bulb to cool. Visually inspect fuses to see if any are blown ⇒ page 322.
Replace the bulb according to the instructions ⇒ . Bulbs should only
be rep l
aced by new identical models. Bulb information is displayed on
the bulb socket or on the bulb itself.
In general, never touch the bulb glass directly. The heat of the bulb
would cause the fingerprint to evaporate and condense on the reflector.
This will impair the brightness of the headlight.
Check if the new bulb is working. If the bulb is not working, it may not
have been correctly fitted, it could be damaged or the connector may
not be correctly connected.
Every time a bulb for the headlights is replaced, visit a specialised
workshop to check the headlights.

nection.
● Close the battery cover, or replace the positive pole cap 1)
. WARNING
Incorrectly jump starting could cause the battery to explode resulting in
serious injur
y. Please observe the following rules to minimise the risk of
a battery explosion:
● All work involving the vehicle battery and electrical system can cause
corro
sion, fire and serious electric shocks. Always read and take into ac-
count the safety warnings and standards before beginning work on the
battery ⇒ page 288, Vehicle battery.
● Always protect your eyes with suitable working goggles and never
lean o
ver the vehicle battery.

If and when
Instructions for tow starting In general, the vehicle should not be started by towing. Jump-starting is
much mor
e pr
eferable ⇒ page 337.
For technical reasons, the following vehicles can not be tow started:
● Vehicles with an automatic gearbox.
● Vehicles with an electronic parking brake, given that it is possible that
the brake w
ill not be disengaged.
● If the vehicle battery is flat, it is possible that the engine control units do
not operat
e correctly.
However, if your vehicle must absolutely be tow-started (manual gearbox):
● Engage the 2nd or 3rd gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warning lights.
● Release the clutch when both vehicles are moving.
● As soon as the engine starts, press the clutch and move the gear lever
into neutral
. This helps to prevent a collision with the towing vehicle. CAUTION
When tow-starting, fuel could enter the catalytic converter and damage it.
Towing instructions Tow-rope or tow-bar
When to
w
ing, the tow bar is the safest and vehicle friendly way. You should
only use a tow-rope if you do not have a tow-bar. A tow-rope should be slightly elastic to avoid damage to both vehicles. It is
advi
sable to use a tow-rope made of synthetic fibre or similarly elastic mate-
rial.
Only secure the tow rope or tow bar to the tow ring or specially designed
fitting.
Vehicles with a factory fitted towing device , can only be used for towing
with a tow-bar, specially designed to fit on a tow hitch ball ⇒ page 233.
Towing vehicles with an automatic gearbox
Note the following for a towed vehicle:
● Make sure the gear selector lever is in the N position.
● Do not
drive faster than 50 km/h (30 mph) when towing a vehicle.
● Do not tow further than 50 km (30 miles).
● If a breakdown truck is used, the vehicle must be towed with the front
wheels r
aised. Note the following instructions for towing four wheel drive
vehicles.
Instructions for towing four-wheel-drive vehicles
Four wheel drive vehicles can be towed using a toolbar or tow rope. If the
vehicle is towed with the front or rear axle raised, the engine must be turned
off to avoid transmission damage.
For vehicles with a double clutched DSG ®
(direct shift gearbox) the instruc-
tions for towing vehicles with an automatic gearbox apply ⇒ page 341.
Situations in which the vehicle should not be towed
In the following cases, the vehicle should not be towed but transported on a
trailer or special vehicle:
● If the vehicle gearbox does not contain lubricant due to a fault.
● If the vehicle battery is flat and, as a result, the electronic steering lock
and electronic
parking brake cannot be disengaged if applied.
● If the vehicle to be towed has an automatic gearbox and the distance to
be cov
ered is greater than 50 km (30 miles). Safety First Operating instructions Practical tips Technical Data
