Service Precaution

WARNING: IF SO EQUIPPED WITH 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.

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 stored speed.

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

switch is kept on while the vehicle in 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.

10A–2 CRUISE CONTROL SYSTEM

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, and
the vehicle automatically runs at the stored speed .

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 decelerates 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: 

D

When the brake pedal is pressed.

D

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

D

When the select lever is shifted to any position other
than “D”, “3”, “2” or “L”. (A/T)

D

When the cancel switch is operated.

D

When the vehicle speed exceeds about 20 km/h
over the vehicle speed stored in the memory.

D

Turning the RESUME/ACCEL switch will return the
vehicle to the speed stored in the cruise control
memory.

2. Complete Cancellation:

D

When the starter switch or the main switch is turned
off.

D

When the fail-safe function is activated.

D

When the vehicle speed is about 38.5 km/h.
