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 un der-inflation has not reached the
level to trigger illumination of th e TPMS low tire pressure telltale.
Your vehicle has also been equi pped 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 syst em detects a malfunction, the
telltale will flash fo r approximately one minute and then remain
continuously illumina ted. 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.

uuWhen Driving uLaneWatchTM*
Driving
LaneWatchTM*
LaneWatch is an assistance system that allows you to check the passenger side rear
areas displayed on the audio/in formation screen when the turn signal is activated to
the passenger’s side. A camera in the passenger side door mirror monitors these
areas and allows you to check for vehicles, in addition to your visual check and use
of the passenger door mirror. You can also keep the system on for your convenience
while driving.1 LaneWatchTM*
Important Safety Reminder
Like all assistance systems, LaneWatch has
limitations. Over reliance on LaneWatch may result in
a collision.
The LaneWatch func tion can be affected by weather,
lighting (including headli ghts and low sun angle),
ambient darkness, camera condition, and loading.
The LaneWatch may not prov ide the intended display
of traffic to the side and rear under the following
conditions:
•Your vehicle’s suspension has been altered,
changing the height of the vehicle.
•Your tires are over or under inflated.•Your tires or wheels are of varied size or
construction.
3WARNING
Failure to visually confirm that it is safe to
change lanes before doing so may result in
a crash and serious injury or death.
Do not rely only on LaneWatch while
driving.
Always look in your mi rrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.

Driving
■Customizing the La neWatch settings
You can customize the following items using the audio/information screen.
• Show with Turn Signal : Selects whether LaneWatch monitor comes on when
you operate the tu rn signal lever.
• Display Time after Turn Signal Off: Changes the remaining LaneWatch display
time after you pull the turn signal lever back.
• Reference Line : Selects whether the reference lines appear on the LaneWatch
monitor.
• Display : Adjusts display settings.
2Customized Features P. 325
■Reference Lines
Three lines that appear on the screen can give
an idea of how far the vehicles or objects on
the screen are from your vehicle, respectively.
If an object is near line 1 (in red), it indicates
that it is close to your vehicle whereas an
object near line 3 is farther away.
1LaneWatchTM*
The LaneWatch camera view is restricted. Its unique
lens makes objects on the screen look slightly
different from what they are.
LaneWatch display does not come on when the shift
lever is in
( R.
For proper LaneWatch operation:
•The camera is located in the passenger side door
mirror. Always keep this area clean. If the camera lens
is covered with dirt or moisture, use a soft, moist cloth
to keep the lens clean and free of debris.
•Do not cover the camera lens with labels or stickers
of any kind.
•Do not touch the camera lens.
1 Reference Lines
The area around the reference line 1 (red) is very close to
your vehicle. As always, make sure to visually confirm
the safety of a lane change before changing lanes.
The distance betwee n your vehicle and lines 1, 2 and
3 on the screen vary depending on road conditions
and vehicle loading. For ex ample, the reference lines
on the screen may seem to appear closer than the
actual distances when the rear of your vehicle is more
heavily loaded.
Consult a dealer if:
•The passenger side door mirr or, or area around it is
severely impacted, resulting in changing the
camera angle.
•The LaneWatch display doe s not come on at all.

Driving
Collision Mitigation Braking SystemTM (CMBSTM)
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM is designed to alert you when the
potential for a collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
1 Collision Mitigation Braking SystemTM (CMBSTM)
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It doe s not prevent collision nor
stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions:

Driving
■How the system works1How the system works
When the CMBS
TM activates, it may automatically
apply the brake. It will be canceled when your vehicle
stops or a potential coll ision is not determined.
The radar sensor is in
the lower bumper.
The camera is located
behind the rearview
mirror.
The system starts monitoring the roadway ah ead when your vehicle speed is about
3 mph (5 km/h) and there is a vehicle in front of you.
When to use
The CMBSTM activates when:●The speed difference between your vehicle and a vehicle or pedestrian detected
in front of you becomes about 3 mph (5 km/h) and over with a chance of a
collision.
●Your vehicle speed is about 62 mph (100 km/h) or less and the system determines
there is a chance of a collision with:
- Vehicles detected in front of you that ar e stationary, oncoming, or traveling in your
same direction.
- A pedestrian who is detected in front of you.
●Your vehicle speed is above 62 mph (100 km/h), and the system determines there
is a chance of a collision with a vehicle detected in front of you traveling in your
same direction.
