INTRODUCTION - SPECIAL ACCESSORIES

WARNINGS

This vehicle is equipped with a starting system known as Smart-Key where the traditional ignition key has been replaced with an electronic key "T.E.G." (Transmitter for Entry and go) combined with an electronic key reader and TEG-Reader radio frequency receiver.

The vehicle is not switched on/started up by inserting the key in the ignition switch (which is no longer present) and turning it but by inserting the TEG in the TEG Reader and activating the START/STOP button.

Access to the vehicle through radiofrequency recognition of the remote control incorporated in the TEG takes place in entirely the same as with the traditional remote control incorporated in the key fob.

The distribution of the power supply to the vehicle (ignition-controlled INT, INT/A, AVV, etc.) is managed by the steering lock node and takes place in entirely the same way as for models equipped with a traditional key.

The following documentation often still uses the expressions Key ON, Key OFF, ignition-operated power supply (INT) or key to MAR, key to STOP, key to AVV. These must be interpreted in accordance with the following summary table:

Key ONTEG inserted in TEG Reader
Key OFFTEG removed from TEG Reader
ignition controlled power supply (INT)TEG inserted into TEG Reader
key on MARTEG inserted in TEG Reader
key on STOPTEG removed from TEG Reader
key on AVVTEG inserted and START/STOP button pressed

To prevent serious damage to the electrical and electronic components, never try and start the engine with the battery earth lead slack.

Never pull the leads or wiring using force because this would result in the cables being disconnected from the connectors or terminals.

Disconnect all the control units and electronic devices when carrying out arc welding operations on the bodyshell.

Before replacing a fuse, check that the circuirt protected is not faulty.

When replacing fuses, make sure that the new fuse is the correct amperage. Do not use fuses that have a higher or lower amperage than required.

PRECAUTIONS

When working on electrical components always follow the precautions described below very carefully:

  • Remove rings, wrist watches and other metal objects.
  • Take care over electrical arcs: Even if the voltage is 12V, the battery can produce high currents if there is a short circuit, creating arcs or sparks that can be dangerous to the mechanic or create a fire hazard;
  • Take care over high tensions. The electronic ignition system produces voltages of 20,000V and more which could be very dangerous. Take great care when working on or near these components.
  • Prevent fire risks. Do not smoke when working close to the battery or components which get hot during usage (e.g. halogen bulbs) or in the area of the engine compartment when the engine is still hot.

Before working on the electrical system (connectors, electrical components, wiring, etc.) turn the ignition key OFF and DISCONNECT THE BATTERY.

If the battery is disconnected the Steering Lock Node remains in the condition (unlocked or locked) that it is in: during workshop operations and repairs, whenever it is necessary to turn the steering wheel with the battery disconnected, leave the TEG inserted when the battery is disconnected. The steering will therefore remain released and free to turn.

PROCEDURE FOR INITIALIZING DOOR NODES

Following a power supply failure to the control units (for example, battery disconnected) the system must be initialized once again following the instructions below working with the TEG inserted and the doors and windows closed.

- completely open the driver''s door window keeping the operating button pressed for at least 3 seconds after the (lower) end of travel position

- completely close the driver''s door window keeping the operating button pressed for at least 3 seconds after the (upper) end of travel position

- carry out the same operations for the passenger window

- make sure that the initialization is correct by checking that the windows work properly in automatic mode
