Replacing the key battery
Fig. 69 Master key:
Opening the cover
We recommend you have the batteries changed in a qualified
workshop. If you decide to change the used battery yourself, follow
the steps below:
– Carefully prise apart the key ⇒ fig. 69 A
and the cover B us-
ing a coin.
– Remove the cover in the direction of the arrow.
– Remove the used battery from the cover.
– Insert the new battery. Make sure that the “+” symbol on the
battery is facing downwards. The correct polarity is indicated on
the cover.
– After inserting the battery, align the cover and key and press
the two parts together.
For the sake of the environment
Used batteries must be disposed of at an appropriate waste facility or
through an authorised service, given that their components can affect the
environment.
Note
● The system must be re-synchronised after each battery replacement to
be able to lock and unlock the vehicle using the remote control
⇒ page 106.
● The new battery must be of the same type as the original. 
Electronic immobiliser
The electronic immobiliser is designed to prevent unauthor-
ised persons from starting up the vehicle.
There is an electronic chip inside the key which automatically deactivates
the immobiliser when the key is inserted into the ignition lock. The electron-
ic immobiliser is enabled automatically when the ignition key is removed
from the ignition lock after coming to a stop.
If an uncoded key is used, the message SAFE will appear in the trip recorder
display.
Note
● The engine can only be started using an original SEAT key with the cor-
rect code.
● It may not be possible to start the engine with the key if there is another
ignition key from a different make of vehicle on the same key tab. 

Unlocking and locking
Activating the childproof lock
– Turn the key in the direction of the arrow ⇒ fig. 77.
Deactivating the childproof lock
– Turn the key in the opposite direction of the arrow.
When the childproof lock is enabled, the inside door handle will not work
and the door can only be opened from the outside. 
Remote control key Description
The remote control key will lock and unlock the vehicle with-
out having to insert the key in the lock. The following functions are available:
● Locking and unlocking the vehicle
● Unlocking the tailgate
All the turn signals will flash as confirmation when the vehicle is locked or
unlocked. Furthermore, the interior lights will automatically light up when
the vehicle is unlocked and go out when the vehicle is locked, provided that
the switches are in the courtesy light position.
The remote control transmitter and the battery are integrated into the han-
dle of the key. The receiver is in the interior of the vehicle. The maximum
range depends on different circumstances. The range is reduced when the
battery starts to lose power.
The remote control incorporates a foldaway key that can be used to manual-
ly lock or unlock the vehicle, as well as to start the engine. If the receiver has been repaired or replaced, or if a replacement key is
used, the system will need re-programming by a qualified workshop. Only
then will you be able use the remote control again.
The remote control meets all relevant authorisation requirements and has
been approved by the Federal Approvals Office for Telecommunications of
the Federal Republic of Germany. All components are marked in accordance
with the current legal requirements. This certification forms the basis for of-
ficial approval for use in other countries.
Note
● The remote control is automatically disabled when the ignition is switch-
ed on.
● The function of the remote control may be impaired by interference from
other nearby radio signals (e.g. from a mobile phone or TV transmitter) if
these are in the same frequency range. 

238Checking and refilling levels
Winter operation
The battery is drained more in cold weather, which means that the starting
power is reduced. For this reason, have the battery checked and charged if
necessary before the start of winter.
Replacing the battery
A replacement battery must have the same capacity, voltage and current rat-
ing. It must also have the same dimensions as the original, factory-fitted
battery and have sealed caps. The SEAT batteries which have been specially
developed fulfil the maintenance, performance and safety specifications for
your vehicle.
We recommend you use maintenance-free batteries.
WARNING
● All work on batteries requires specialist knowledge. If work is re-
quired on the battery, this should be performed by a Technical Service or
qualified workshop. Danger of caustic burns and explosion!
● The battery must not be opened. Never try to change the battery's liq-
uid level. Explosive gas is released from the battery that could cause an
explosion.
CAUTION
● The battery holder and clamps must always be correctly secured.
● Before starting any work on the battery, always observe the warnings
listed under ⇒ 
.
For the sake of the environment
 Batteries contain toxic substances including sulphuric acid and lead.
Therefore, they must be disposed of in line with environmental regulations
and must not be disposed of with ordinary household waste. Make sure dis-
connected batteries cannot tip over. Sulphuric acid could be spilt! Important safety warnings for handling a vehicle battery
The battery is located at the back of the engine compartment
⇒ page 296.
Wear eye protection
Battery acid is very corrosive and caustic. Wear protective
gloves and eye protection!
Fires, sparks, open flames and smoking are prohibited!
A highly explosive mixture of gases is released when the bat-
tery is under charge.
Keep children away from acid and batteries!
WARNING
Always be aware of the danger of injury and chemical burns as well as
the risk of accident or fire when working on the battery and the electrical
system:
● Wear eye protection. Protect your eyes, skin and clothing from acid
and particles containing lead.
● Battery acid is very corrosive and caustic. Wear protective gloves and
eye protection. Do not tilt the batteries. This could spill acid through the
vents. Rinse battery acid from eyes immediately for several minutes with
clear water. Then seek medical care immediately. Neutralise any acid
splashes on the skin or clothing with a soapy solution, and rinse off with
plenty of water. If acid is swallowed by mistake, consult a doctor immedi-
ately.
● Fires, sparks, open flames and smoking are prohibited. When han-
dling cables and electrical equipment, avoid causing sparks and electro-
static charge. Never short the battery terminals. High-energy sparks can
cause injury. 
