uuWhen Driving uForward Collision Warning (FCW)
*
Driving
Forward Collision Warning (FCW)
*
Alerts you when it detects the possibility of your vehicle colliding with the vehicle in
front of yours.
If the system determines a collision is possible, it gives both visual and audible alerts.
u Take appropriate action to prevent a collision (apply the brakes, change lanes,
etc.).■How the system works
The system may give warnings of potential collisions when your vehicle speed is
above about 10 mph (15 km/h).
1 Forward Collision Warning (FCW)
*
Important Safety Reminder
FCW cannot detect all objects ahead and may not
detect a given object; accuracy of the system will vary
based on weather, speed and other factors. FCW
does not include a braking function. It is always your
responsibility to safely operate the vehicle and avoid
collisions.
You can change the Forward Collision Warning
Distance setting or turn the system on and off.

uuWhen Driving uLane Departure Warning (LDW)

Driving
Lane Departure Warning (LDW)
*
Alerts you when the system detects a possibility of your vehicle unintentionally
crossing over left or right side lane markings.
If your vehicle is getting too close to detected
left or right side lane markings without a turn
signal activated, LDW will give audible and
visual alerts.
The beeper sounds and the Lane Departure
message appears on the MID, letting you
know that you need to take appropriate
action.
The system begins to search for lane markings when all the following conditions are
met:
• The vehicle is traveling between 40 and 90 mph (64 and 145 km/h).
• The vehicle is on a straight or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.■
How the System Works
1Lane Departure Warning (LDW)
*
Important Safety Reminder
Like all assistance systems, LDW has limitations.
Over-reliance on LDW may result in a collision. It is
always your responsibility to keep the vehicle within
your driving lane.
LDW only alerts you when lane drift is detected
without a turn signal in use. LDW 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 and avoid collisions.

uuWhen Driving uVehicle Stability Assist (VSA ®), aka Electronic Stability Control (ESC), System
Driving
Vehicle Stability Assist (VSA ®), aka Electronic Stability Control (ESC), SystemVSA ® helps to stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine output and selectively applying the brakes.
When VSA® activates, you may notice that the
engine does not respond to the accelerator.
You may also notice some noise from the
hydraulic system. You will also see the
indicator blink.■
VSA ® Operation
1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control (ESC), System
The VSA ® may not function properly if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the ai r pressures as specified.
When the VSA ® indicator comes on and stays on
while driving, there may be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and cor ner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.

Driving
Super Handling-All Wheel Drive
TM
(SH-AWD ®)
*
The system controls and transfers varying amounts of engine torque to each wheel
in accordance with the driving conditions.
SH-AWD ® helps to enhance driving stability, and le ts you handle situations like
slippery surfaces, such as snow, sand, mud, and steep hills, better than when driving
with two wheel drive. However, the system does not help to enhance braking. Be
precautious about the following:
• It is still your responsibility to drive safely when you steer, accelerate, and apply
brakes.
• Leave a sufficient margin when braking on slippery surfaces.Tire Pressure Monitoring System (TPMS)
Monitors the tire pressure while you are
driving. If your vehicle’s tire pressure becomes
significantly low, the low tire pressure/TPMS
indicator comes on and a message appears on
the MID.
1Super Handling-All Wheel Drive
TM (SH-AWD ®)
*
NOTICEAvoid continuously driving in sand or mud where a
wheel is likely to spin out, and do not drive once the
SH-AWD ® indicator starts blinking. Driving
continuously under such conditions can damage the
system’s torque distribution unit.
Do not drive through deep water.
The SH-AWD ® system may not function properly if
tire type and size are mixed.
Make sure to use the same size and type of tire, and
the air pressures as specified. 2 Tire and Wheel Replacement P. 4271Tire Pressure Monitoring System (TPMS)
Conditions such as low ambient temperature and
altitude change di rectly affect tire pressure and can
trigger the low tire pr essure/TPMS indicator to come
on.

Comes On or Blinks P. 473
Tire pressure checked and inflated in:•Warm weather can become under-inflated in
colder weather.•Cold weather can become over-inflated in warmer

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain
correct tire pressure, even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction
indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the system detects a malfunction, the
telltale will flash for approximately one minute and then remain
continuously il luminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

Driving
Collision Mitigation Braking System
TM
(CMBS
TM
)*
Can assist you when there is a possibility of your vehicle colliding with a vehicle
detected in front of yours. The CMBS
TM is designed to alert you when a potential
collision is determined, as well as to reduce your vehicle speed when a collision is
deemed unavoidable to help minimize collision severity.
■How the system works
1 Collision Mitigation Braking System
TM (CMBS
TM)*
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It does not prevent a collision
nor stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately according to the driving
conditions.
The CMBSTM may not activate or may not detect a
vehicle in front of your vehicle under the following
conditions:
•The distance between your vehicle and the vehicle
ahead of you is too short.•A vehicle cuts in front of you at a slow speed, and
it brakes suddenly.•When you accelerate rapidly and approach the
vehicle ahead of you at high speed.•The vehicle ahead of you is a motorcycle or other
small vehicle.•A vehicle suddenly crosses in front of you.•When you drive on a curved or winding road that
makes it difficult for the sensor to properly detect a
vehicle in front of you.•When there are pedestrians or animals in front of
your vehicle.
A radar sensor starts to monitor if there is a vehicl e in front of you when your
vehicle speed is above about 10 mph (15 km/h).
The radar sensor is
in the front grille.
The CMBS
TM activates when the speed difference between your vehicle and a
vehicle detected in front of you becomes more than about 10 mph (15 km/h) with
a chance of a collision.
