1. Check that the "CRUISE" indicator light within the

combination meter illuminates when the "ON/OFF" switch is
switched "ON".

2. Press the "ON/OFF" switch again, and check that the

"CRUISE" indicator light within the combination meter goes
out.

CRUISE CONTROL SETTING

3. Push the "COAST/SET" switch.
4. Check to be sure that cruise control is activated when the

"COAST/SET" switch is released.
NOTE: If the vehicle speed decreases to approximately 15
km/h (9 mph) below the set speed because of climbing a hill
for example, it is normal for the cruise control to be can-
celled. When the vehicle speed becomes approximately 40
km/h (25 mph) or less, driving at constant speed will be can-
celled even if the vehicle speed does not decrease approxi-
mately 15 km/h (9 mph) or more.

3. Push the "ACC/RES" switch.
4. Check to be sure that acceleration continues while the

"ACC/RES" switch is pushed, and that the speed at the time
it was released becomes the constant driving speed.
NOTE: Acceleration can be continued even if the vehicle
speed has passed the high-speed limit [approximately 200
km/h (125 mph)]. But the constant driving speed when the
"ACC/RES" switch is released will be recorded as the
high-speed limit.

SPEED-REDUCTION SETTING

1. Switch the "ON/OFF" switch to "ON".
2. Set to the desired speed, above approximately 40 km/h (25

mph).

3. Push the "COAST/SET" switch.
4. Check to be sure that deceleration continues while the

"COAST/SET" switch is pushed, and that the speed at the
time it was released becomes the constant 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.

CANCELLATION

1. Switch the "ON/OFF" switch to "ON".
2. Set to the desired speed, above approximately 40 km/h (25

mph).

3. 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 "CANCEL" switch is pushed.
(2) The brake pedal is depressed.

4. At a vehicle speed of approximately 40 km/h (25 mph) or

higher, check if when the "ACC/RES" switch is pushed, the
vehicle speed returns to the speed before auto-cruise
control driving was cancelled, and constant speed driving
occurs.

5. When the "ON/OFF" switch is switched to "OFF" while

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