Service Precaution

WARNING:  THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS).  REFER TO THE SRS
COMPONENT AND  WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS  OR THE SRS WIRING.  WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE
SRS COMPONENTS OR THE SRS WIRING, REFER
TO  THE SRS SERVICE INFORMATION.  FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL  INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.

CAUTION:  Always use the correct fastener in the
proper location.  When you replace a fastener, use
ONLY the exact part  number for that application.
ISUZU will call out those fasteners that require a
replacement after removal.  ISUZU will also call out
the  fasteners that require thread lockers or thread
sealant.  UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings  (Paints, greases, or
other corrosion inhibitors) on threaded fasteners or
fastener joint interfaces.  Generally, such coatings
adversely  affect the fastener torque and the joint
clamping force, and may damage the fastener.
When you install fasteners, use the correct
tightening sequence and specifications.  Following
these instructions can help you avoid damage to
parts and systems.

CRUISE CONTROL SYSTEM

General Description

The cruise control keeps the vehicle running at a fixed 
speed until a signal canceling this fixed speed is 
received. 
When the main switch “AUTO CRUISE" is turned on 
with the vehicle in the running mode, the battery voltage 
is applied to the control unit.  When a signal from the 
control switch is input to the control unit while the 
vehicle is in this state, the cruise control actuator is 
activated to operate the system.  Also, while the system 
is operating, the “AUTO CRUISE" indicator light in the 
meter assembly lights up.

1 . SET/COAST Switch Function

1. Set Function: When the SET/COAST switch is 

pressed and released with the main switch on, the 
speed at which the vehicle is running at that 
moment is stored in the memory, and the vehicle 
automatically runs at the speed stored.

2. Coast-Down Function: When the SET/COAST 

switch is kept on while the vehicle is running, the 
vehicle decelerates during that time.  The speed at 
which vehicle is running when the control switch is 
turned off is stored in the memory, and the vehicle 
automatically returns to the stored speed.

3. Tap-Down Function: When the SET/COAST switch 

is turned on and off instantaneously while the 
vehicle is running, the vehicle decelerates a mile for 
each on/off operation.  The vehicle speed at which 
the vehicle was running when the SET/COAST was 
turned off last is stored in the memory, and the 
vehicle automatically returns to this stored speed.

2 . RESUME/ACCEL Switch Function

1. Resume Function: When the RESUME, ACCEL 

switch is turned on/off after the system is 
temporarily deactivated by pressing the brake or 
clutch pedal while the vehicle is running, the vehicle 
resumes,  the speed stored before the system was 
released.

2. Accelerate Function: When the RESUME/ACCEL 

switch is kept on after the system is released 
completely, the vehicle accelerates its speed during 
that time.  The vehicle speed at which the vehicle 
was running when the switch was turned off is 
stored in the memory, and the vehicle automatically 
returns to this speed.

3. Tap-Up Function: When the RESUME/ACCEL 

switch is turned on and off instantaneously while the 
vehicle is running, the vehicle accelerates a mile for 
each on/off operation.  The vehicle speed at which 
the vehicle was running when the switch was turned 
off last is stored in the memory, and the vehicle 
automatically returns to this stored speed.

3 . CANCEL Function

1. Temporary Cancellation: 

• When the brake pedal is pressed.

• When the clutch pedal is pressed. (M/T)

• When the select lever is shifted to any position 

other than “D", “3", “2" or “L". (A/T)

• When the vehicle speed has decreased about 20 

km/h or more than the stored speed.

2. Complete Cancellation: 

• When the starter switch or the main switch is 

turned off.

• When the failsafe function is activated.
