110 STARTING AND OPERATING
To Resume
If there is a set speed in memory, push the RES
(resume) button and remove your foot from the
accelerator pedal. The instrument cluster
display will show the last set speed.
Resume can be used at any speed above
20 mph (32 km/h) when only Fixed Speed
Cruise Control is being used.
Resume can be used at any speed above 0 mph
(0 km/h) when ACC is active.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
While ACC is set, you can increase speed by
pushing the SET (+) button, or decrease speed
by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+), or SET (-) button once
will result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre-
ments until the button is released. The new
set speed is reflected in the instrument
cluster display.
Metric Speed (km/h)
Pushing the SET (+), or SET (-) button once
will result in a 1 km/h speed adjustment.
Each subsequent tap of the button results in
an adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h
increments until the button is released. The
new set speed is reflected in the instrument
cluster display.
NOTE:
When you override and push the SET (+) button
or SET (-) button, the new set speed will be the
current speed of the vehicle.
When An ACC Distance Is Also Set:
NOTE:
When you use the SET (-) button to decel-
erate, if the engine’s braking power does not
slow the vehicle sufficiently to reach the set
speed, the brake system will automatically
slow the vehicle.
The ACC system applies the brake down to
15 mph (24 km/h) when following a vehicle
ahead.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while
climbing uphill or descending downhill. This
is normal operation and necessary to main-
tain set speed. When driving uphill and down-
hill, the ACC system will cancel if the braking
temperature exceeds normal range (over-
heated).
Setting The Following Distance In ACC
The specified following distance for ACC can be
set by varying the distance setting between four
bars (longest), three bars (long), two bars
(medium) and one bar (short). Using this
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming
a set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate
too sharply for safe operation. Failure to
follow these warnings can result in a collision
and death or serious personal injury.
