uuWhen Driving uAdaptive Cruise Control (ACC) with Low Speed Follow (LSF)
Driving
■Automatic ca ncellation
The beeper sounds and a message appears on the driver information interface and
the head-up display when ACC with LSF is automatically canceled. Any of these
conditions may cause the ACC with LSF to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the front grille gets dirty.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the AC C with LSF range is too close to your
vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
The ACC with LSF automatic cancellation ca n be also triggered by the following
causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfastene d when the vehicle is stationary.
• The vehicle stops for more than 10 minutes.
• The power system is turned off.
1Automatic cancellation
Even though ACC with LSF has been automatically
canceled, you can still resu me the prior set speed.
Wait until the condition that caused ACC with LSF to
cancel improves, then press the RES/+ button.

Driving
Lane Keeping Assist System (LKAS)
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides tactile and visual al erts if the vehicle is detected drifting out of its lane.1Lane Keeping Assist System (LKAS)
Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicle control. The system does
not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
2 Driver Information Interface Warning and
Information Messages P. 114
Do not place objects on the instrument panel.
Objects may reflect on th e windshield and prevent
correct detection of the traffic lanes.
The LKAS only alerts you when lane drift is detected
without a turn signal in use. The LKAS may not detect
all lane markings or lane departures; accuracy will
vary based on weather, speed, and lane marker
condition. It is always your responsibility to safely
operate the vehicle an d avoid collisions.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly or may work
improperly under the certain conditions:
2 LKAS Conditions and Limitations P. 410
The LKAS may not function as designed while driving
in frequent stop and go traf fic, or on roads with
sharp curves.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 383
When you operate the turn signals to chan ge lanes, the system is suspended, and
resumes after the signals are off.
If you make a lane change without operat ing the turn signals, the LKAS alerts
activate, and torque is applied to the steering.
■Front Sensor
Camera
Monitors the lane
lines■Tactile and visual alerts
Rapid vibrations on the steering wheel
and a warning display alert you that
the vehicle is drifting out of a
detected lane.
■Steering input assist
The system applies torque to the steering to keep the vehicle between the left
and right lane lines. The applied torque becomes stronger as the vehicle gets
closer to either of the lane lines.

■The system operation is suspended if
you:
• Set the wipers to continuous operation.
u Turning the wipers off resumes the
LKAS.
• Set the wiper switch to AUTO and the
wipers operate continuously.
u The LKAS resumes when the wipers stop
or operate intermittently.
• Decrease the vehicle speed to about 40
mph (64 km/h) or less.
u Increasing the vehicle speed to about 45
mph (72 km/h) or more resumes the
LKAS.
• Depress the brake pedal.
u The LKAS resumes and starts detecting
the lane lines again once you release the
brake pedal.
■The LKAS may automatica lly be suspended when:
• The system fails to detect lane lines.
• The steering wheel is quickly turned.
• You fail to steer the vehicle.
• Driving through a sharp curve.
• Driving at a speed in excess of approximately 90 mph (145 km/h).
Once these conditions no longer exist, the LKAS automatically resumes.
When the LKAS is suspended,
the lane lines on the driver
information interface and the
head-up display change to
contour lines, and the beeper
sounds (if activated).

Driving
This button is on the driver side control panel.
To partially disable VSA ® functionality/
features, press and hold it until you hear a
beep.
Your vehicle will have normal braking and
cornering ability, but tra ction control function
will be less effective.
To restore VSA ® functionality/features, press
the (VSA ® OFF) button until you hear a
beep.
VSA ® is turned on every time you turn the
power system on, even if you turned it off the
last time you drove the vehicle.
■VSA ® On and Off1 Vehicle Stability Assist ® (VSA ®), aka Electronic Stability Control
(ESC), System
In certain unusual conditions when your vehicle gets
stuck in shallow mud or fr esh snow, it may be easier
to free it with the VSA ® temporarily switched off.
When the button is pressed, the traction control
function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the VSA ® off if
you are not able to free it when the VSA ® is on.
Immediately after freeing your vehicle, be sure to
switch VSA ® on again. We do not recommend driving
your vehicle with the VSA ® system switched off.
You may hear a motor sound coming from the motor
compartment while system checks are being
performed immediately after turning the power
system on or while driving. This is normal.

uuWhen Driving uTire Pressure Monitoring System (TPMS)
Continued
Driving
Tire Pressure Monitoring System (TPMS)
Instead of directly measuring the pressure in each tire, the TPMS on this vehicle
monitors and compares the rolling radius and rotational characteristics of each
wheel and tire while you are driving to determine if one or more tires are
significantly under-inflated. This will caus e the low tire pressure/TPMS indicator to
come on and a message to appear on the driver information interface.
You must start TPMS calibration every time you:
• Adjust the pressure in one or more tires.
• Rotate the tires.
• Replace one or more tires.
Before calibrating the TPMS:
• Set the cold tire pressure in all four tires.
2 Checking Tires P. 468
Make sure:
•The vehicle is at a complete stop.
• The gear position is in
(P.
• The power mode is in ON.
■TPMS Calibration
1Tire Pressure Monitoring System (TPMS)
The system does not monitor the tires when driving
at low speed.
Conditions such as low ambient temperature and
altitude change directly a ffect tire pressure and can
trigger the low tire pressure/TPMS indicator to come on.
Tire pressure checked and inflated in:
•Warm weather can beco me under-inflated in
colder weather.
•Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPMS indicator will not come
on as a result of over inflation.
The TPMS may not function pr operly if tire type and
size are mixed. Make sure to use the same size and
type of tire. 2 Checking and Maintaining Tires P. 468
The low tire pressure/TPMS indicator may come on
with a delay or may not come on at all when:
•You rapidly accelerate, decelerate, or turn the
steering wheel.
•You drive on snowy or slippery roads.
•Tire chains are used.
The low tire pressure/TPMS indicator may come on
under the following conditions:
•There is a heavier and uneve n load on the tires than
the condition at calibration.
•Tire chains are used.
