■Sequential Mode Operation1Sequential Mode Operation
Each paddle shif t operation makes a single or double
gear change.
To change gears continuously, release the paddle
shifter before pulling it again for the next gear.
If the sequential mode gear selection indicator blinks
when you try to shift up or down, this means your
vehicle speed is not in its allowable gear range or the
protection of transmissi on system is necessary.
Slightly accelerate to shift up and decelerate to shift
down while the indi cator is blinking.
When the transmission is in
( S and SPORT or
INDIVIDUAL mode, to prioritize the engine
performance enhancement, the transmission may
not allow for shifting up while the engine speed is
low.

Super Handling-All Wheel DriveTM (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 lets you handle situations like

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. 621

uuWhen Driving uBlind spot information System
Continued
Driving
Blind spot information System
Is designed to detect vehicles in specified alert zones adjacent to your vehicle,
particularly in harder to see areas commonly known as “blind spots.”
When the system detects vehicles approach ing from behind in adjacent lanes, the
appropriate indicator comes on for a few seconds, providing assistance when you
change lanes.
■How the system works
1 Blind spot information System
Important Safety Reminder
Like all assistance systems, blind spot information
system has limitations. Over reliance on blind spot
information system may result in a collision.
The blind spot information system alert indicator may
not come on under the following conditions:
•A vehicle does not stay in the alert zone for more
than two seconds.
•A vehicle is parked in a side lane.•The speed difference betw een your vehicle and the
vehicle you are passing is greater than 6 mph (10
km/h).
•An object not detected by the radar sensors
approaches or passes your vehicle.
•A vehicle running in the adjacent lane is a
motorcycle or other small vehicle.
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 the blind spot
information system wh en changing lanes.
Always look in your mi rrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.

■Assistive braking
Assistive braking provides a visual and audible alert when the vehicle is moving
between approximately 1 and 6 mph (2 and 10 km/h) and there is the possibility of
a collision with a detected wall or other ob stacles, as well as providing assistance
with braking.
If the only rear sensors are turned off usi ng the parking sensor system, the assistive
braking is not working when reversing.
