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).

8E-4 CRUISE CONTROL SYSTEM
Components and functions
Component Function
Cruise control actuator
assembly with control mod-
uleCruise control module:
Executes centralized control by means of a microcomputer over all functions
including setting a constant speed, resuming it, setting coast, limiting minimum
speed and cancelling cruise control.
Cruise control actuator (stepping motor & clutch) :
Actuates accelerator pedal through cruise cable and arm according to a signal
from cruise control module to control vehicle speed.
Cruise main switch This switch has a momentary contact type button to turn the cruise control
system ON and OFF.
SET COAST switch When this switch is rotated (ON) and then released (OFF) while vehicle is run-
ning at a speed 40 km/h (25 mile/h) or higher, vehicle speed at that OFF
moment is stored in memory and it is maintained (constant cruising).
Rotating this switch (ON) continuously during constant cruising keeps slowing
down vehicle speed as long as it is ON. When it is released (OFF), vehicle
speed at that moment is stored in memory and vehicle starts constant cruising.
ACCEL RESUME switch When this switch is rotated (ON) during constant cruising, vehicle speed keeps
increasing as long as it is ON. When it is released (OFF), vehicle speed at that
moment is stored in memory and vehicle starts constant cruising. If vehicle
speed is higher than 40 km/h (25 mile/h) after cruise control is cancelled, turn-
ing this switch ON momentarily will resume the speed at which vehicle was run-
ning before cancellation.
CANCEL switch When this switch is pressed (ON), cruise control (accelerator pedal control) is
cancelled.
Vehicle speed sensor (VSS) The vehicle speed sensor (VSS) is mounted on the transfer or transmission.
The VSS converts vehicle speed into pulse signal and send it to the cruise con-
trol module.
Stop lamp switch The stop lamp switch has 2 contact points. One contact point closes when the
brake pedal is depressed to light the stop lamp and provides a voltage signal to
the cruise control module. This signal, when inputted cancels cruise control
(sets the accelerator pedal free).
The other contact point (brake pedal position switch) opens when the brake
pedal is depressed, to shut off the power to the magnetic clutch in the actuator,
thereby cancelling cruise control (setting the accelerator pedal free).
This switch is installed to cancel cruise control (constant cruising) without fail.
Clutch pedal position switch
(M/T vehicle only)When the clutch pedal is depressed, the clutch pedal position switch closes and
provides a ground signal to cruise control module.
The cruise control module cancels cruise control (accelerator pedal control)
when this signal is inputted.
Transmission range switch
(Park/Neutral position switch)
(A/T vehicle only)When the selector lever is places in either “P” or “N” position, the transmission
range switch closes and provides a ground signal to cruise control module. The
cruise control module cancels cruise control (accelerator pedal control) when
this signal is inputted.
PCM – Throttle opening sig-
nal (4 A/T vehicle only)Throttle opening signal is inputted from PCM.
From this signal, the cruise control module detects the throttle opening and
uses it as one of the factors to output the overdrive and TCC OFF command sig-
nal to PCM.

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).
