uuWhen Driving uVehicle Stability AssistTM (VSA ®), aka Electronic Stability Control (ESC), System
Continued
Driving
Vehicle Stability AssistTM (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during corn ering 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 ou tput 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 brake system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability AssistTM (VSA® ), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there ma y be a problem with the
system. While this may not interfere with normal
driving, have your vehi cle 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 corner 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.
The vehicle stability assist
TM (VSA ®) system, vehicle
stability assistTM (VSA ®) OFF, adaptive cruise control
(ACC) with low speed follow, and safety support
indicators may come on in amber along with a
message in the multi-information display when you
set the power mode to ON after reconnecting a
battery.
Drive a short distance at more than 12 mph (20
km/h).
Each indicator should go off. If any do not, have your
vehicle checked by a dealer.

uuWhen Driving uAgile Handling Assist
Driving
Agile Handling Assist
Lightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehicle’s stability and performance during
cornering.1 Agile Handling Assist
The agile handling assist ca nnot enhance stability in
all driving situations. You still need to drive and
corner at speeds appropriate for the conditions and
always leave a sufficient margin of safety.
When the VSA ® system indicator comes on and stays
on while driving, the agil e handling assist does not
activate.
You may hear a sound coming from the engine
compartment while the agile handling assist is
activated. This is normal.

uuWhen Driving uSuper Handling-All Wheel DriveTM (SH-AWD ®)*
Driving
Super Handling-All Wheel DriveTM (SH-AWD® )*
The system controls and tran sfers varying amounts of engine torque to each wheel
in accordance with the driving conditions.
SH-AWD ® helps to enhance driving stability, and lets you handle situations like
sli ppe r y sur f a c es , suc h a s o n w e t, i cy , o r sno wy r oa ds , b e tt e r t ha n wh e n dr iv ing wi t h
two wheel drive. However, the system do es 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.1Super Handling-All Wheel DriveTM (SH-AWD ®)*
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. 561
Do not continuously spin the front tires of your
vehicle. Continuously spinning the front tires can
cause damage to the transmission and SH-AWD ®
unit.
If the SH-AWD indicator blinks while driving, it
indicates the differential te mperature is too high. If
this happens, pull to the side of the road when it is
safe, change the gear position to
( P, and idle the
engine until the indicator goes out.

Driving
Collision Mitigati on Braking SystemTM (CMBSTM)
The system can assist you when it determine s there is a possibility of your vehicle
colliding with a vehicle or a pedestrian de tected in front of your vehicle. 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 does not prevent collisions
nor stop the vehicle automati cally. It is still your
responsibility to operate th e 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: 2 CMBS

■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 system starts monitoring the roadway ahead when your vehicle speed is about 3
mph (5 km/h) or above and will search for a vehicle in front of you. The radar sensor is
behind the emblem.
The camera is
located behind the
rearview mirror.
The CMBS
TM activates when:●The speed difference between your vehicl e 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 are 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.

Adaptive Cruise Control (ACC) with Low Speed
Follow
Helps maintain a constant vehicle speed and a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate
and stop your ve hicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follo w slows your vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.
1 Adaptive Cruise Control (ACC) with Low Speed Follow
Important Reminder
As with any system, there are limits to ACC with Low
Speed Follow. Use the brake pedal whenever
necessary, and always keep a safe interval between
your vehicle and other vehicles.
For directions on the prop er handling of the radar
sensor, refer to the following page.
2 Radar Sensor P. 484
3WARNING
Improper use of ACC with Low Speed
Follow can lead to a crash.
Use ACC with Low Speed Follow only when
driving on expressways or freeways and in
good road and weather conditions.
3WARNING
ACC with Low Speed Follow has limited
braking capability and may not stop your
vehicle in time to avoid a collision with a
vehicle that quickly stops in front of you.
Always be prepared to apply the brake
pedal if the conditions require.
■Vehicle speed for ACC wi th Low Speed Follow: A vehicle is detected ahead
within ACC with Low Speed Follow range – ACC with Low Speed Follow
operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with Low Speed Follow range – ACC with
Low Speed Follow operates at the speed of about 25 mph (40 km/h) or above.
■Gear position for ACC wi th Low Speed Follow: In (D or (S.
