INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION
*1: When the CVT selector lever position is N position, the engine start condition is different according to the vehicle speed.
• At vehicle speed of 4 km/h (2 MPH) or less, the engine can start only when the brake pedal is depressed.
• At vehicle speed of 4 km/h (2 MPH) or more, the engine can start even if the brake pedal is not depressed. (It is the same as “Engine
stall return operation while driving”.)
*2: When the CVT selector lever position is in any position other than P position and when the vehicle speed is 5 km/h (3 MPH) or more,
the engine stop condition is different.
• Press and hold the push-button ignition switch for 2 seconds or more. (When the push-button ignition switch is pressed for too short a
time, the operation may be invalid, so properly press and hold to prevent an incorrect operation.)
• Press the push-button ignition switch 3 times or more within 1.5 seconds. (Emergency stop operation)

SYSTEM DESCRIPTION
• The NVIS (NATS) is an anti-theft system by registering an Intelligent Key ID in to the vehicle and prevents
the engine being started by an unregistered Intelligent Key. It has a higher protection against auto thefts that
duplicate mechanical key.
• It performs the ID verification when starting the engine in the same way as the Intelligent Key system. But, it
performs the NVIS (NATS) ID verification when inserting the Intelligent Key and performs the Intelligent Key
ID verification when carrying the Intelligent Key.
• The Intelligent Key system of L32 is not the same as the conventional models. The mechanical key inte-
grated in the Intelligent Key cannot start the engine. When the Intelligent Key battery is discharged, the NVIS
(NATS) ID verification memorized to the transponder integrated with Intelligent Key is performed by inserting
the Intelligent Key into the key slot. If the verification results are OK, the engine start operation can be per-
formed by the push-button ignition switch operation.
• Locate the security indicator and apply the anti-theft system equipment sticker, forewarn that the NVIS
(NATS) is onboard with the model.
• The security indicator always blinks when the Intelligent Key is removed from the key slot and when the
power supply position is in LOCK position.
• Intelligent Key can be registered up to 4 keys (Including the standard ignition key) on request from the
owner.
• The specified registration is required when replacing ECM, BCM or Intelligent Key. The registrations proce-
dure for NVIS (NATS) and registration procedure for Intelligent Key when installing the BCM, refer to CON-
SULT-III Operation Manual NATS-IVIS/NVIS.
