110 STARTING AND OPERATING
To Set A Desired Speed
Turn the Cruise Control on.
NOTE:
The vehicle should be traveling at a steady speed and on
level ground before pushing the SET (+) or SET (-) button.
When the vehicle has reached the desired speed, push
the SET (+) or SET (-) button and release. Release the
accelerator and the vehicle will operate at the selected
speed.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
When the Cruise Control 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 until the button is released, then the
new set speed will be established.
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 until the button is released, then the
new set speed will be established.
To Accelerate For Passing
While the Cruise Control is set, press the accelerator to
pass as you would normally. When the pedal is released,
the vehicle will return to the set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to maintain the
vehicle set speed.
The Cruise Control system maintains speed up and down
hills. A slight speed change on moderate hills is normal.
On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Cruise Control.
WARNING!
Cruise Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose control
and have an accident. Do not use Cruise Control in
heavy traffic or on roads that are winding, icy,
snow-covered or slippery.
To Resume Speed
To resume a previously set speed, push the RES button
and release. Resume can be used at any speed above
20 mph (30 km/h).
To Deactivate
A tap on the brake pedal, pushing the CANC (cancel)
button, or normal brake pressure while slowing the vehicle
will deactivate the Cruise Control without erasing the set
speed from memory.
The following conditions will also deactivate the Cruise
Control without erasing the set speed from memory:
 Vehicle parking brake is applied
 Stability event occurs
 Gear selector is moved out of DRIVE
 Engine overspeed occurs
