On a steep grade, the vehicle may slow
down or speed up slightly while going
uphill or downhill.
To increase cruise control set
speed:
OJF055044
Follow either of these procedures:
• Move the lever up (to RES+), and hold
it. Your vehicle set speed will increase
by 10 km/h (5 mph). Release the lev‐
er at the speed you want.
• Move the lever up (to RES+), and re‐
lease it immediately. The cruising
speed will increase by 1.0 km/h
(1.0 mph) each time you move the
lever up (to RES+) in this manner.
• You can set the speed to 180 km/h
(110 mph).
To decrease the cruise control set
speed:
OJF055043
Follow either of these procedures:
• Move the lever down (to SET-), and
hold it. Your vehicle set speed will de‐
crease by 10 km/h (5 mph). Release
the lever at the speed you want.
• Move the lever down (to SET-), and
release it immediately. The cruising
speed will decrease by 1.0 km/h
(1.0 mph) each time you move the
lever down (to SET-) in this manner.
• You can set the speed to 30 km/h
(20 mph).
To temporarily accelerate with the
cruise control on:
If you want to speed up temporarily
when the cruise control is on, depress
the accelerator pedal. Increased speed
will not interfere with cruise control op‐
eration or change the set speed.
To return to the set speed, take your
foot off the accelerator.
If you move the lever down (to SET-) at
increased speed, the cruising speed will
be set again.
NOTICE
Be careful when accelerating tempo‐
rarily, because the speed is not con‐
trolled automatically at this time
even if there is a vehicle in front of
you.
