Caution: Do not use the cruise control on slippery roads, steeply graded roads,
or in heavy traffic of heavy or varying volume. Failure to follow these CAUTIONS
could possibly cause you to loose control of the vehicle and result in damage
to the vehicle and personal injury.
Cruise control is a speed control system that maintains
a desired vehicle speed under normal driving conditions. Steep grades up
or down may cause variations in the selected speeds. The cruise control
system has the following capabilities:
The cruise control system consists of the following main components:
| • | The multi-function turn signal lener |
| | The multi-function turn signal lener includes an ON-OFF-R/A switch and
a SET/COAST switch |
| • | The cruise control module |
| • | The cruise control cable |
| • | The vehicle speed sensor |
| • | The cruise control release switch |
| | The cruise control switch disengages the cruise system. |
| | The stoplamp switch disengages the cruise system. |
The cruise control release and the stoplamp switches are mounted on
the brake pedal bracket. When the brake pedal is depressed, the cruise control
system is electrically disengaged by these switches. The throttle returns
to the idle position.
MULTI-FUNCTION TURN SIGNAL LEVER
OFF-ON-R/A Switch
The OFF-ON-R/A switch
has the following 3 positions:
| | The ON position turns the cruise control system ON. |
| | The OFF position turns the cruise control system OFF. |
| | The R/A switch position has the following 3 main functions: |
| - | The system will enter the resume mode when the OFF-ON-R/A switch is
held in the R/A (Resume/Accelerate) position momentarily. The vehicle speed
must exceed 40 km/h (25 mph) at the time of activation in
order for the cruise control operation to return to the last cruise speed
setting. |
| - | The system will enter the accelerate mode when the OFF-ON-R/A switch
is held in the R/A position for more than one second. |
| - | To increase the cruise speed, the vehicle must be traveling at least
40 km/h (25 mph) and the ON-OFF-R/A switch held in the R/A position
until the vehicle reaches the desired cruise speed. |
| - | The system will maintain the new cruise speed when the OFF-ON-R/A switch
is released to the ON position. |
| - | This function increases the cruise speed by increments of 2 km/h
(1 mph). One tap equals a 2 km/h (1 mph) increase. The
cruise must be engaged and operating in order to use this function. |
| - | Press the OFF-ON-R/A switch toward the R/A position and release quickly
or tap the lever in order to operate the tap-up function. Do not hold the
lever in the R/A position or the system will go into the accelerate mode. |
SET/CRUISE Button Switch
The cruise control SET/CRUISE button switch is located in the end of
the multi-function turn signal lever. The SET/CRUISE button switch has the
following 3 main functions:
The cruise speed sets when the following actions occur:
| • | The SET/CRUISE button switch is depressed and released. |
| • | The OFF-ON-R/A switch is in the ON position. |
| • | The vehicle speed exceeds 40 km/h (25 mph). |
The cruise speed sets at the speed at which the vehicle is travelling
when the button is released. The cruise speed will be within 2 km/h
(1 mph) of the engaged speed.
The system will cruise until one of the following actions occurs:
| • | The OFF-ON-R/A switch is moved to the OFF position. |
| • | The brake pedal is pressed. |
| • | The ignition switch is turned to the OFF position. |
The driver can decrease the cruise speed by completing the following
actions:
| • | Fully depress and hold the SET/CRUISE button switch. This action
disengages the cruise system and allows the throttle to return to the idle
position. |
| • | When the vehicle slows to the desired cruise speed, release the
SET/CRUISE button switch. This action will set the new cruise speed. |
The tap-down function permits the driver to decrease the cruise speed
in increments of 2 km/h (1 mph). One tap equals a 2 km/h
(1 mph) decrease. The cruise must be engaged and operating in order
to use this function.
Press and quickly release or tap the SET/CRUISE button switch in order
to operate the tap-down function. Holding the SET/CRUISE button inward will
cause the system to go into the CRUISE mode.
Press the accelerator at any time in order to override the cruise system.
The vehicle will return to the last set cruise speed after the accelerator
is released.
Cruise Control Module
The cruise control system uses a cruise control module to obtain and
hold any desired vehicle cruise speed above a minimum speed of 40 km/h
(25 mph). The module contains the following 2 components:
| • | An electronic controller |
| | The electronic controller monitors the following operations: |
| - | The multi-function turn signal lener |
| - | The cruise control release inputs |
| - | The brake switch inputs |
| - | Operates the electric stepper motor |
| | The stepper motor moves the internal band in response to the controller
in order to maintain the desired cruise speed. The internal band is linked
to the throttle lever via the cruise control cable. |
Cruise Control Cable
The cruise control cable is adjustable. The cable provides a physical
connection between the cruise control module and the engine throttle lever.
Vehicle Speed Sensor
The vehicle speed sensor (VSS) is mounted to the automatic transaxle.
The VSS provides a low voltage alternating current (AC) signal to the powertrain
control module (PCM). The PCM converts the AC signal to a pulse width modulated
direct current (DC) signal. The signal is sent to the cruise control module
at a rate of 4,000 pulses per mile.
Cruise Control Release Switch and Stoplamp Switch
The cruise control release switch and the stoplamp switch are used in
order to disengage the cruise control system. The switches are mounted on
the brake pedal bracket in order to disengage the system electrically when
the brake pedal is pressed.
The brake pedal interrupts the flow of current to the cruise control
module. The cruise speed of the vehicle at brake actuation will be stored
in the cruise control module memory.
Improper cruise control operation can be caused by mechanical or electrical
problems. Perform the following inspections in order to resolve any cruise
control operating concerns:
| • | Inspect the cruise control wiring for bare or broken wires. |
| • | Inspect for loose or backed-out terminals. |
| • | Inspect for a properly adjusted cruise control cable. |
If the preliminary inspections do not resolve the concerns or the system
remains inoperative, refer to
Cruise Control System Check
