Driving
Intelligent Variable Torque Management (i-VTM4TM)
AWD System*
The Intelligent Variable To rque Management (i-VTM4TM) AWD System is a full time
all wheel drive system that automatically controls and transfers varying amount of
engine torque to all wheels independently according to the driving conditions.
You still need to exercise the same care when accelerating, steering, and braking
that you would in a two wheel drive vehicle.
Avoid continuously driving on slippery surfaces where a wheel is likely to spin out,
and do not drive if the All-wheel drive ( AWD) Indicator starts blinking. Driving
continuously under such conditions can damage the system’s torque distribution
unit.
If the All-wheel drive (AWD ) Indicator blinks while driving, it indicates the
differential temperature is too high. If this happens, pull to the side of the road
when it is safe, shift to park, and idle the engine until the indicator goes out. If the
indicator does not go out, take your vehi cle to a dealer to have it checked.1Intelligent Variable Torq ue Management (i-VTM4TM) AWD
System*
NOTICE
Do not continuously spin the front tires of your
vehicle. Continuously spinning the front tires can
cause transmission or re ar differential damage.
The Intelligent Variable Torque Management (i-
VTM4
TM) 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. 522

uuHonda Sensing ®u Collision Mitigation Braking SystemTM (CMBSTM)
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.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)
Important Safety Reminder
The CMBSTM is designed to reduce the severity of an
unavoidable collision. It does not prevent collisions nor
stop the vehicle automatically. It is still your
responsibility to operate the 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 certain conditions:
2 CMBSTM Conditions and Limitations P. 430
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 467
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 465
1How the system works
Rapid vibrations on the st eering wheel alert you
when your vehicle speed is between 19 and 62 mph
(30 and 100 km/h) with an oncoming vehicle
detected in front of you.
When the CMBS
TM activates, it may automatically
apply the brake. It will be canceled when your vehicle
stops or a potential colli sion is not determined.
The system starts monitoring the roadway ah ead 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 CMBS
TM 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 there is a chance of a
collision with an oncoming detected vehicle or a pedestrian in front of you. The camera is
located behind the
rearview mirror.

Press and hold the butt on until the beeper
sounds to switch the system on or off.
When the CMBS
TM is off:
• The CMBSTM 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 turned on every time you start
the engine, even if you turned it off the last
time you drove the vehicle.
■CMBSTM On and Off1 Collision Mitigation Braking SystemTM (CMBSTM)
The CMBS
TM may automatically shut off, and the
CMBSTM indicator will come and stay on under certain
conditions:

Driving
■The system operatio n is suspended if
you:
• Set the wipers to HI .
u Turning the wipers o ff or setting it to LO
or MIST resumes the LKAS.
• Decrease the vehicle speed to about 40
mph (64 km/h) or less.
u Increasing the vehicle speed to about 45
mph (72 km/h) or more resumes the
LKAS.
• Depress the brake pedal.
u The LKAS resumes and starts detecting
the lane lines again once you release the
brake pedal.
• Your vehicle is driving to the right or the left
of the lane.
• Set the wiper switch to AUTO and the
wipers operate continuously.
u The LKAS resumes when the wipers stop
or operate intermittently.1The system operation is suspended if you:
You can change the setting for the LKAS.
LKAS suspended beep on and off can be selected.

Safety When Performing Maintenance
Some of the most important safety precau tions are given here. However, we cannot
warn you of every conceivable hazard that can arise in performing maintenance.
Only you can decide whether you should perform a given task.
• To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the battery and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the engine and exhaust can ignite them, causing a fire.
• To clean parts, use a co mmercially available degreas er or parts cleaner, not
gasoline.
• Wear eye protection and protective clothi ng when working with the battery or
compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Only operate the engine if th ere is sufficient ventilation.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on le vel ground, the parking brake is set, and
the engine is off.
• Be aware that hot parts can burn you.
u Make sure to let the engine and exhaust system cool thoroughly before
touching vehicle parts.
• Be aware that moving parts can injure you.
u Do not start the engine unless instruct ed, and keep your hands and limbs away
from moving parts.
u Do not open the hood while the Auto Idle Stop function is activated.

Handling the Unexpected
Emergency Engine Stop
The ENGINE START/STOP button may be used to stop the engine due to an
emergency situation even while driving. If you must stop the engine, do either of the
following operations:
• Press and hold the ENGINE START/STOP button for about two seconds.
• Firmly press the ENGINE START/STOP button three times.
The steering wheel will not lock. However, because turning off the engine disables
the power assist the engine provides to the steering and braking systems, it will
require significantly more physical effort an d time to steer and slow the vehicle. Use
both feet on the brake pedal to slow down the vehicle and stop immediately in a
safe place.
The transmission automa tically changes to
(P after the vehicle comes to a complete
stop.
Then, the power mode changes to VEHICLE OFF.
Then press the ENGINE START/STOP button twice without depressing the brake
pedal to change the mode to VEHICLE OFF.
1 Emergency Engine Stop
Do not press the ENGINE START/STOP button while
driving unless it is absolute ly necessary for the engine
to be turned off.
If you press the ENGINE START/STOP button while
driving, the beeper sounds.

Handling the Unexpected
If the Battery Is Dead
Turn off the power to electric devices, such as audio and lights. Turn off the engine,
then open the hood. 1.Pull up on the engine cover, remove it from
the pins.
u Start on the passenger side and lift the
outermost edge of the cover.
u Move towards the driver side while
applying uniform upward pressure.
2. Connect the first jump er cable to your
vehicle’s battery + terminal.
3. Connect the other end of the first jumper
cable to the booster battery + terminal.
u Use a 12-volt booster battery only.
u When using an automotive battery
charger to boost your 12-volt battery,
select a lower charging voltage than
15-volt. Check the charger manual for
the proper setting.
4. Connect the second jumper cable to the
booster battery - terminal.
■Jump Starting Procedure1If the Battery Is Dead
Securely attach the jumper cables clips so that they
do not come off when the e ngine vibrates. Also be
careful not to tangle the ju mper cables or allow the
cable ends to touch each other while attaching or
detaching the jumper cables.
Battery performance degrades in cold conditions and
may prevent the engi ne from starting.
3WARNING
A battery can explode if you do not follow
the correct procedure, seriously injuring
anyone nearby.
Keep all sparks, open flames, and smoking
materials away from the battery.
