AUTO-CRUISE CONTROL SWITCH CHECK

M1172001100262

AUTO-CRUISE CONTROL MAIN SWITCH CHECK

1. Turn the ignition switch to the "ON" position.
2. Check that the indicator light within the combination meter

illuminates when the main switch is switched "ON."

Auto-cruise Control Setting

1. Switch "ON" the main switch.
2. Drive at the desired speed, above approximately 40 km/h.

(25 mph)

3. Push the auto-cruise control switch in the direction of arrow.
4. Check to be sure that when the switch is released the speed

is the desired constant speed.
NOTE: If the vehicles speed decreases to approximately 15
km/h (9 mph) below the set speed because of climbing a hill
for example, the auto-cruise control will be cancelled.

Speed-increase Setting

1. Set to the desired speed.
2. Push the auto-cruise control switch in the direction of arrow.
3. Check to be sure that acceleration continues while the

switch is held, and that after it is released the constant
speed at the time when it was released becomes the driving
speed.
NOTE: Acceleration can be continued even if the vehicle
speed has passed the high-speed limit [approximately 200
km/h (124 mph)]. But the speed when the auto-cruise con-
trol switch is released will be recorded as the high-speed
limit.

Speed-reduction Setting

1. Set to the desired speed.
2. Push the auto-cruise control switch in the direction of arrow.
3. Check to be sure that deceleration continues while the

switch is pressed, and that after it is released the constant
speed at the time when it was released becomes the driving
speed.
NOTE: When the vehicle speed reaches the low limit
[approximately 40 km/h (25 mph)] during deceleration, the
auto-cruise control will be cancelled.

Return to the Set Speed Before Cancellation and
Auto-cruise Control Cancellation

1. Set the auto-cruise speed control.
2. When any of the following operations are performed while at

constant speed during auto-cruise control, check if normal
driving is resumed and deceleration occurs.

(1) The auto-cruise control switch is pushed in the direction

of arrow.

(2) The brake pedal is depressed.
(3) The clutch pedal is depressed. (M/T)
(4) The selector lever is moved to the "N" range. (A/T)

3. At a vehicle speed of 40 km/h (25 mph) or higher, check if

when the "RESUME" switch is switched "ON," the vehicle
speed returns to the speed before auto-cruise control driving
was cancelled, and constant speed driving occurs.

4. When the main switch is turned to the "OFF" while driving at

constant speed, check if normal driving is resumed and
deceleration occurs.
