To Vary The Speed Setting
To Increase Or Decrease The Set Speed
When Cruise Control is set, you can increase the
sp
eed by pushing the RES (+) button, or decrease
speed by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the RES (+) button, or SET (-) button
once will result in a 1 mph speed adjustment.
Ea
ch 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 estab
-
lished.
Metric Speed (km/h)
Pushing the RES (+), or SET (-) button once will
result in a 1
km/h speed adjustment. Each
s
u
bsequent 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 estab
-
lished.
To Accelerate For Passing
While the Cruise Controls is set, press the
accelerator 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.
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 (32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the 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
Pushing the on/off button, or placing the ignition in
t
h
e OFF position, erases the set speed from
memory.
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.
