WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual
mentioned in FOREWORD of this manual.

CRUISE CONTROL SYSTEM 8E-5
Cancel Conditions
Constant cruising is cancelled under the following conditions.
•Ignition switch is turned OFF.
•Cruise main switch is turned OFF.
•Vehicle speed has slowed down to lower than minimum operating speed (40 km/h (25 mile/h)).
•*Vehicle speed varies beyond cancel speed range (–15 km/h, –9 mile/h) from preset speed.
•*Brake pedal is depressed. (Stop lamp switch is turned ON).
•*Clutch pedal is depressed (Clutch pedal position switch is turned ON) (For M/T vehicle).
•*Selector lever is shifted to N range (Park/Neutral position switch in transmission range switch is turned ON).
•*CANCEL switch is turned ON.
Diagnosis
Diagnosis Table
PCM – Overdrive and TCC
off command signal outputWhen the throttle opening for the vehicle speed exceeds the specified value
during cruise control, the cruise control module sends this signal to PCM. PCM
uses this signal as one of signals to control 4-A/T.
Cruise main switch indicator
lampIn the state with the ignition switch ON and the cruise control system OFF,
pressing this switch once and releasing it will activate the cruise control system
and the cruise control module will cause the indicator lamp to light up.
“CRUISE” indicator lamp It lights up when cruise control (accelerator pedal control) is functioning. Component Function
NOTE:
When constant cruising is cancelled under above any condition with * (asterisk), vehicle speed before
cancellation can be resumed by operating ACCEL RESUME switch, provided that vehicle speed is
higher than 40 km/h (25 miles/h).
