■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between objects and the background.
• Driving into low sunlight (e.g., at dawn or dusk).

• Driving on curvy, winding, or undulating roads.
• The road is hilly or the vehicle is approaching the crest of a hill.
■CMBSTM Conditions and Limitations1CMBSTM Conditions and Limitations
Do not paint, or apply any coverings or paint to radar
sensor area. This can impact CMBS
TM operation.
Have your vehicle checked by a dealer if you find any
unusual behavior of the system (e.g., the warning
message appears too frequently).
If the front of the vehicle is impacted in any of the
following situations, the ra dar sensor may not work
properly. Have your vehi cle checked by a dealer:
•The vehicle impacted a bump, curb, chock,

■Detection limitations
• A vehicle or pedestrian suddenly crosses in front of you.
• The distance between your vehicle and the vehicle or pedestrian 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 or pedestrian ahead of you
at high speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter or other small
vehicle.
• When there are animals in front of your vehicle.
• When you drive on a curved, winding or und ulating road that makes it difficult for
the sensor to properly detect a vehicle in front of you.
• The speed difference between your vehi cle and a vehicle in front of you is
significantly large.
• An oncoming vehicle suddenly comes in front of you.
• Another vehicle suddenly comes in fr ont of you at an intersection, etc.

Limitations applicable to pedestrian detection only
• When there is a group of people in front of your vehicle walking together side by
side.
• Surrounding conditions or belongings of the pedestrian alter the pedestrian’s
shape, preventing the system from recogn izing that the person is a pedestrian.
• When the pedestrian is shorter than about 3 feet (1 meter) or taller than about 7
feet (2 meter) in height.
• When a pedestrian blends in with the background.
• When a pedestrian is bent over or squa tting, or when their hands are raised or
they are running.
• When several pedestrians are walking ahead in a group.
• When the camera cannot correctly identify that a pedestrian is present due to an
unusual shape (holding luggage, body position, size).
■Automatic shutoff
The CMBSTM may automatically shut itself off and the CMBSTM indicator comes and
stays on when:
• The temperature inside the system is high.
• You drive off-road or on a mountain ro ad, or curved and winding road for an
extended period.
• An abnormal tire condition is detected (wrong tire size, flat tire, etc.).
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
Once the conditions that caused the CMBS
TM to shut off improve or are addressed
(e.g., cleaning), the system comes back on.

uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)
Driving
The CMBSTM may activate even when you are aware of a vehicle ahead of you, or
when there is no vehicle ahead. Some examples of this are:
■When Passing
Your vehicle approaches another vehicle ah ead of you and you change lanes to pass.
■At an intersection
Your vehicle approaches or passes another ve hicle that is making a left or right turn.
■On a curve
When driving through curves, your vehicle comes to a point where an oncoming
vehicle is right in front of you.
■Through a low bridge at high speed
You drive under a low or na rrow bridge at high speed.
■Speed bumps, road work sites, train tracks, roadside objects, etc.
You drive over speed bumps, st eel road plates, etc., or your vehicle approaches train
tracks or roadside objects [such as a traffic sign and guard rail] on a curve or, when
parking, stationary vehicles and walls.
■With Little Chance of a Collision1 Collision Mitigation Braking SystemTM (CMBSTM)
For the CMBS
TM to work properly:
Always keep the radar sensor cover clean.
Never use chemical solvents or polishing powder for
cleaning the sensor cover. Clean it with water or a
mild detergent.
Do not put a sticker on the radar sensor cover or
replace the radar sensor cover.

uuParking Your Vehicle uWhen Stopped
Driving
Always confirm the electric parking brake is set, particularly if you are parked on an
incline.1 When Stopped
In extremely cold temperatures, the parking brake
may freeze up if applied. If such temperatures are
expected, do not apply the parking brake but, if
parking on a slope, either turn the front wheels so
they will contact the curb if the vehicle rolls down the
slope or block the wheels to keep the vehicle from
moving. If you do not take either precaution, the
vehicle may roll unexpectedly, leading to a crash.
