Charging the battery
The vehicle battery should be charged by a specialised workshop only, as
batteries using special technology have been installed and they must be
charged in a controlled environment ⇒ 
. SEAT recommends visiting a
Technical Service. Replacing a vehicle battery
The battery has been developed to suit the conditions of its location and
has special safety features. If the battery must be replaced, consult a Tech-
nical Service for information on electromagnetic compatibility, the size and
maintenance, performance and safety requirements of the new battery in
your vehicle before you purchase one. SEAT recommends you have the bat-
tery replaced by a Technical Service.
Use only maintenance-free genuine batteries conforming to TL 825 06 and
VW 7 50 73 Standards. These standards must be dated April 2008 or later.
Vehicles fitted with the Start-Stop system are equipped with a special bat-
tery. Therefore, this battery must only be replaced by another of the same
specifications.
Disconnecting the vehicle's battery
If you must disconnect the battery from the electrical system, please note
the following:
●
Switch off the ignition and all electrical equipment.
● The vehicle must be unlocked before disconnecting the battery, other-
wise the alarm will be triggered.
● First disconnect the negative cable and then the positive ⇒ 
.
Connecting the vehicle's battery
● Before reconnecting the battery, switch off the engine, the ignition and
electric devices.
● First reconnect the positive cable and then the negative ⇒ 
.
Different control lamps may light up after connecting the battery and switch-
ing the ignition on. They will be turned off after a short trip at a speed of
between 15 - 20 km/h (10 - 12 mph). If the warning indicators remain lit,
please visit a specialised workshop to have the vehicle checked.
If the battery has been disconnected for a long time, it is possible that the
next service date is not displayed or calculated correctly ⇒ page 17. Respect

264Practical information
Changing bulbs
Introduction
Changing bulbs requires a certain amount of manual skill. If you are unsure,
SEAT recommends that you consult a Technical Service or request assis-
tance from a specialist. In general a specialist is needed if, in addition to
the bulbs, other vehicle components require removal.
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:
● Exterior detail ⇒ page 6
● Lights and visibility ⇒ page 84
● Working in the engine compartment ⇒ page 180
● Vehicle tools ⇒ page 246
● Fuses ⇒ page 261
WARNING
If the road is not well-lit and the vehicle is not clearly visible to other
drivers, there 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 observe the warnings ⇒ page 180. In any vehicle, the engine com-
partment is a hazardous area and could cause severe injury.
● The bulbs H4, HB4 and H7 are pressurised and might explode on
changing them.
● Only replace the bulbs concerned when they have cooled.
● Never replace bulbs alone if you are not familiar with the operations
necessary. If you are not sure about procedures then visit a Specialised
workshop 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 are not replaced correctly on the
headlamp framework, the electrical installation may be damaged, especial-
ly if water is allowed to enter. 

282Description of specifications
● Passengers.
● Total equipment.
● Roof load, included in the carrier.
WARNING
Exceeding the maximum authorised weight and the load on the axles
could cause damage to the vehicle, accidents and serious injuries.
● The real load on the axles should never exceed the maximum permit-
ted.
● The load and its distribution in the vehicle have effects on the vehicle
handling and the braking ability. Always drive at a suitable speed.
CAUTION
Distribute the load as uniformly and as low down on the vehicle as possible.
When transporting heavy objects in the luggage compartment, these
should be placed as far forward as possible or over the rear axle to have as
little influence on handling as possible. 
Information on fuel consumption
The consumption and emission values indicated do not refer to one specific
vehicle. They are only to be used to compare the values of the different ve-
hicle versions. The fuel consumption and CO 2 emissions of a vehicle not on-
ly depend on the effective use of fuel. They also depend on your driving
style and other non-technical factors.
Calculation of fuel consumption
Fuel consumption and emission values are determined according to the cur-
rent version of the 715/2007/EC or 80/1268/EEC regulation and are valid
for the vehicle kerb weight. The specifications do not refer to an individualvehicle. To measure the fuel consumption, two measuring cycles are carried
out on a rolling road test bed. The test criteria are as follows:
Urban cycleMeasurement of the urban cycle starts with an engine cold
start. City driving is then simulated at between 0 and 50 km/
h (0 and 31 mph).
Road cycle
In the road cycle simulation, the vehicle undergoes frequent
acceleration and braking in all gears, as in normal everyday
driving. The road speed ranges from 0 to 120 km/h (0 and
75 mph).
CombinedThe average combined consumption is calculated with a
weighting of around 37 % for the urban cycle and 63 % for
the road cycle.
CO
2 emis-
sions of the
combinationThe exhaust gases are collected during both driving cycles
to calculate carbon dioxide emissions (urban and road). The
gas composition is then analysed to evaluate the CO 2 con-
tent and other emissions.
Note
The kerb weight may vary according to the vehicle equipment. This could
raise consumption and the CO 2 emissions slightly.
Note
In practice, consumption values could be different to the values calculated
based on the 715/2007/EC or 80/1268/EEC regulations. 
