return to the set speed.
Using Speed Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
NOTE:
The Speed 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
Speed 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 CANC
button, or normal brake pressure while slowing
the vehicle will deactivate the Speed Control
without erasing the set speed from memory.
Pushing the on/off button, or placing the
ignition in the OFF position, erases the set
speed from memory.
WARNING!
Speed 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 Speed Control
in heavy traffic or on roads that are winding,
icy, snow-covered or slippery.

Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward
Collision Warning system.
The ACC system:
Does not react to pedestrians,
oncoming vehicles, and stationary
objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance
conditions.
Does not always fully recognize
complex driving conditions, which can
result in wrong or missing distance
warnings.
Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for two seconds in the stop
position. If the target vehicle does not
start moving within two seconds the
ACC system will display a message that
the system will release the brakes and
that the brakes must be applied manu -
ally. An audible chime will sound when
the brakes are released.
WARNING! (Continued)
You should switch off the ACC system:
When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway construc -
tion zones).
When entering a turn lane or highway off
ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
When towing a trailer up or down steep

TO VARY THE ACC SPEED
To Increase Speed
While ACC is set, you can increase the set speed
by pushing the SET (+) button.

The driver's preferred units can be selected
through the instrument panel settings if
equipped. Refer to “Getting To Know Your
Instrument Panel” for more information. The
speed increment shown is dependent on the
chosen speed unit of U.S. (mph) or Metric (km/h):

U.S. Speed (mph)
Pushing the SET (+) button once will result in
a 1 mph increase in set speed. Each subse -
quent tap of the button results in an increase
of 1 mph.
If the button is continually pushed, the set
speed will continue to increase in 5 mph
increments until the button is released. The
increase in set speed is reflected in the

decrements until the button is released. The
decrease in set speed is reflected in the
instrument cluster display.
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.

168STARTING AND OPERATING
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 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 decelerates the vehicle to a
full stop when following a target vehicle.
When you have ACC active and follow a target
vehicle to a standstill, after two seconds you
will either have to push the RES (resume)
button, or apply the accelerator pedal to
reengage the ACC to the existing set speed.
The ACC will bring the vehicle to a complete
stop while following a target vehicle and hold
the vehicle for two seconds in the stop posi -
tion. If the target vehicle does not start
moving within two seconds, the ACC system
will display a message that the system will
release the brakes and that the brakes must
be applied manually. An audible chime will
sound when the brakes are released.
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
distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle
ahead. This distance setting displays in the
instrument cluster display.
Distance Settings

To increase the distance setting, push the
Distance Setting Increase button and release.
Each time the button is pushed, the distance
setting increases by one bar (longer).
To decrease the distance setting, push the
Distance Setting Decrease button and release.
Each time the button is pushed, the distance
setting decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving
vehicle is detected in the same lane, the
1 — Longest Distance Setting (Four Bars)
2 — Long Distance Setting (Three Bars)
3 — Medium Distance Setting (Two Bars)
4 — Short Distance Setting (One Bar)

20_LX_OM_EN_USC_t.book Page 168

STARTING AND OPERATING169
instrument cluster displays the “Sensed Vehicle
Indicator” icon, and the system adjusts vehicle
speed automatically to maintain the distance
setting, regardless of the set speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed
above the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages. (Refer to the infor -
mation on ACC Activation).
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:
The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE” will flash in the instrument cluster display and a chime will
sound while ACC continues to apply its
maximum braking capacity.

Brake Alert

NOTE:
The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the
Forward Collision Warning system is applying
the brakes autonomously.
OVERTAKE AID
When driving with ACC engaged and following a
vehicle, the system will provide an additional
acceleration up to the ACC set speed to assist in
passing the vehicle. This additional acceleration
is triggered when the driver utilizes the left turn
signal (Lane Change Assist feature included) and will only be active when passing on the left
hand side. Switching lanes will not impact the
ACC system if the driver is already traveling at
the set speed.
ACC OPERATION AT STOP
If the ACC system brings your vehicle to a
standstill while following a target vehicle, if the
target vehicle starts moving within two seconds
of your vehicle coming to a standstill, your
vehicle will resume motion without the need for
any driver action.
If the target vehicle does not start moving within
two seconds of your vehicle coming to a
standstill, the ACC with Stop system will cancel
and the brakes will release. A cancel message
will display on the instrument cluster display
and produce a warning chime. Driver
intervention will be required at this moment.
While ACC with Stop is holding your vehicle at a
standstill, if the driver seat belt is unbuckled or
the driver door is opened, the ACC with Stop
system will cancel and the brakes will release. A
cancel message will display on the instrument
cluster display and produce a warning chime.
Driver intervention will be required at this
moment.
