NOTE
This thermometer indicates the ambient temperature in back of front bumper member. Under any one
of the following listed conditions, however, even when the ambient temperature goes up, the
thermometer display does not rise so as to correct the rise of the ambient temperature caused by the
radiant heat of the engine. When the ambient temperature drops, the thermometer reading follows the
change in the temperature.
Be sure to bear this in mind when diagnosing trouble.
• The vehicle speed is 30 km/h (18 mph) or lower.

Theft Deterrent LightS7RS0BA201003
The information display or clock (1) of this vehicle includes a theft deterrent light (2) for the theft preventive purpose.
The BCM makes the theft deterrent light flash at certain interval s after the ignition switch is turned off until it is turned
on again. Also, to check DTCs stored in BCM without usin g a SUZUKI scan tool when diagnosing troubles, it is
possible to identify them by flashing patterns of the theft deterrent light.
Security Alarm Description (If Equipped)S7RS0BA201004
Operation
The security alarm system provides a warning of an abnormal condition to those who are around. Its operation is as
follows. While the system is in the stand- by mode (when 20 seconds or more elapsed after the door is locked using a
keyless entry transmitter or door request switch), BCM monitors door lock status, door switch status and battery power
supply voltage. When it detects an abnormal condition (door is unlocked by some way other than using keyless entry
transmitter or door request switch and opened or cut off BCM power supply voltage temporarily), it activates the
warning buzzer (located in BCM), theft deterr ent light, hazard warning relay and horn relay.
The security alarm system has 2 selectable modes.
• A mode: No operation
• B mode: Theft deterrent light blinks, hazard warning lights blink, warning buzzer (located in BCM) sounds and horn
sounds
When B mode is selected and the door is locked using keyl ess entry transmitter or door request switch, the theft
deterrent light (1) flashes at 0.1 second interval for 20 seconds and the se curity alarm system is set to the stand-by
mode (2). Once it is se t to the stand-by mode, the theft deterrent light blinks at 2 second intervals.
When the system is set to stand-by mode and the door is unlocked by some way other than using keyless entry
transmitter or door request switch and opened or cut off BCM power supply voltage temporarily, the alarm devices
operate according to the selected mode as described above.
The alarm stops under either of the following conditions.
• Ignition switch is turned ON
• A certain time has elapsed since the alarm started
For selection of the mode of the security alarm system , refer to “Security Alarm Mode Selection Procedure (If
Equipped)”.

Diagnostic Information and Procedures
BCM Self-Diagnosis FunctionS7RS0BA204001
• BCM monitors conditions of the system components and its circuit with ignition switch turned to ON position. When
an abnormality in the system oc curs, the area where that abnormality lies is stored in the memory of EEPROM in
BCM.
• DTC can be checked in either one of following ways. – DTC can be checked by SUZUKI scan tool (2) connected to DLC (1).
– DTC can be read from flashing pattern of theft deterrent light (3). Also, DTC is displayed on combination meter
(4) at the same time.
