Never drive with the seat-back folded down and the
tailgate open. 2 Exhaust Gas Hazard P. 64
To lock the seat-back uprig ht, push it backwards until
it locks.
When returning the seat-back to its original position,
push it firmly back. Also, ma ke sure all rear shoulder
belts are positioned in front of the seat-back.
Make sure that the folded seat-back does not press
against the front passenger seat, as this can cause the
weight sensors in the front passenger seat to work
improperly. 2 Passenger Airbag Off Indicator P. 47
Make sure all items in th e cargo area or items

Driving
ACC (Adaptive Cruise Control)*
Maintains a constant vehicle speed and a safe distance between your vehicle and the
vehicle ahead of you without having to keep your foot on the brake pedal or
accelerator.1 ACC (Adaptive Cruise Control)*
Important Safety Reminder
As with any system, th ere are limits to ACC.
Inappropriate use of ACC can result in a serious
accident. Use the brake pedal whenever necessary,
and always keep a safe distance between your vehicle
and other vehicles.
The radar sensor for ACC is shared with the CMBS
TM
(collision mitigation braking systemTM).
2 CMBSTM (Collision Mitigation Braking
SystemTM)* P. 257
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when traveling on open
highways in good weather.When to use
■Vehicle speed for adaptive cruise control:
Desired speed in a range above roughly 25
mph (40 km/h) ~
■Shift positions for adaptive cruise control:
In ( D or (S
The radar sensor is under the
emblem in the front grille.
How to use
■Press the MAIN button on
the steering wheel. ACC (green) is
on in the
instrument panel.
Adaptive cruise control is
ready to use.

uuWhen Driving uACC (Adaptive Cruise Control)*
Driving
The radar sensor monitors the distance be tween your vehicle and a vehicle ahead of
you. When the sensor detects a change in distance, the system compensates it by
accelerating or braking your vehicle in order to maintain the cruising speed you
previously set.
■When in Operation1 When in Operation
If the vehicle ahead of you slows down abruptly, or if
another vehicle cuts in front of you, the beeper
sounds and a message ap pears on the multi-
information display to alert you.
Depress the brake pedal, and keep an appropriate
distance from the vehicle ahead. 2 CMBS
TM (Collision Mitigation Braking
SystemTM)* P. 257
If the CMBS
TM has been turned off, there is no
audible or visible alert available.
Even if the distance between your vehicle and the
vehicle ahead is short, CMBS
TM may not alert you or
ACC may start accelerating your vehicle under the
following circumstances:
•The vehicle ahead of you is going at almost the
same speed as, or faster than your vehicle.
•A vehicle cuts in front of you is going faster than
your vehicle, gradually distancing.
If you do not want to hear a beep when the system
detects a vehicle, or when the vehicle goes out of
ACC range, you can change the pre-running detect
car beep setting. 2 Customized Features P. 94
■When ACC detects a
vehicle within ACC range:■When the vehicle goes
out of ACC range:
a beeper sounds once and a
vehicle icon appears on the
multi- information display. a beeper so
unds once and
the vehicle icon on the
multi- information display
becomes a dotted-line
contour.

• Depress the brake pedal.
■Automatic cancellan
The beeper sounds and a message appears on the multi-information display when
ACC is automatically canceled. Any of these conditions may cause the ACC
cancellation:
• The vehicle speed slows down to 22 mph (35 km/h) and below.
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the front grille gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or dr iving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS or VSA is activated.
• When the VSA indicator comes on.

Continued
Driving
CMBSTM (Collision Mitigation Braking SystemTM)*
Can assist you when there is a possibility of your vehicle colliding with the vehicle in
front of yours. The CMBSTM is designed to alert you, then reduce your vehicle speed
when a possible collision is likely unavoidable to help minimize collision severity.
■How the system works
■When the system activates
1 CMBSTM (Collision Mitigation Braking SystemTM)*
Important Safety Reminder
The CMBSTM is designed to reduce the severity of an
unavoidable collision. It do es not prevent collision nor
stop the vehicle automatically. It is still your
responsibility to operate th e brake pedal and steering
wheel appropriately according to the driving
conditions.
The CMBS
TM 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 ra pidly 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 se nsor 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 detect if there is a vehicle in front of you when your vehicle
speed is above 10 mph (15 km/h).
The radar sensor is under the
emblem in the front grille.
The CMBS
TM activates when the speed difference betw een the two vehicles
becomes more than 10 mph (15 km/h ) with a chance of a collision.
A visual alert or a combination of a visual
alert and an audible alert for a possible
collision.

Press this button for about one second to turn
on and off the system.
When the CMBS
TM is off:
• The beeper sounds.
• The CMBS
TM indicator in the instrument
panel comes on.
• A message on the multi-information display
reminds you that the system is off.
The CMBS
TM is in the previously selected ON or
OFF setting each time yo u start the engine.
■CMBSTM On and Off1CMBSTM (Collision Mitigation Braking SystemTM)*
The CMBSTM may automatically shut off and the
CMBSTM indicator comes and stays on when:•You drive off-road or on a mountain road for an
extended period.
•You drive with the parking brake applied.•You drive in bad weather (rain, fog, snow, etc.)•The radar sensor cover is blocked by dirt, mud, dry
leaves, wet snow, etc.
•An abnormal tire condition is detected (wrong tire
size, flat tire, etc.)
Once the conditions that caused the CMBS
TM to shut
off improve, the system comes back on.
