170 STARTING AND OPERATING
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.
NOTE:
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 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
Clutch pedal is pressed (manual transmis-
sion only)
Pushing the on/off button or placing the ignition
in the OFF position erases the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC) I F
E
QUIPPED
Adaptive Cruise Control (ACC) increases the
driving convenience provided by Cruise Control
while traveling on highways and major
roadways. However, it is not a safety system
and not designed to prevent collisions. The
Cruise Control function performs differently if
your vehicle is not equipped with ACC
Ú page 168.
NOTE:
If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or accelerate
(not to exceed the original set speed) auto-
matically to maintain a preset following
distance, while matching the speed of the
vehicle ahead.
Any chassis/suspension or tire size modifica-
tions to the vehicle will affect the perfor-
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the condi-
tions, 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.
