Driving
Vehicle Stability AssistTM (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps stabilize the vehicle during cornering 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 and motor output and selectively applying the
brakes.
When VSA® activates, you may notice that the
engine and motor do not respond to the
accelerator. You may also notice some noise
from the hydraulic brake sy stem. 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 may 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 Stab ility Control (ESC). The
system also includes a traction control function.
The Vehicle Stability Assist
TM (VSA ®) system, Adaptive
Cruise Control (ACC) with Low Speed Follow, safety
support, low tire pressure/TPMS
*, and parking brake
and brake system (amber) indicators may come on in
amber along with a message in the driver information
interface when you set the power mode to ON after
reconnecting the 12-volt battery.
Drive a short distance at mo re than 12 mph (20 km/h).
Each indicator should go off. If any do not, have your
vehicle checked by a dealer.

Driving
You can turn the system on and off using the driver information interface.
2 Switching the Display P. 119
2 Vehicle Stability Assist Mode P. 131
Your vehicle will have normal braking and cornering ability, but traction control
function will be less effective.
VSA ® is turned on every time you turn the pow er system on, even if you turned it off
the last time you drove the vehicle.
■VSA ® On and Off1 Vehicle Stability AssistTM (VSA® ), aka Electronic Stability Control
(ESC), System
In certain unusual conditions when your vehicle gets
stuck in shallow mud or fr esh snow, it may be easier
to free it with the VSA ® temporarily switched off.
When the VSA ® system is off, the traction control
function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the VSA ® off if
you are not able to free it when the VSA ® is on.
Immediately after freeing your vehicle, be sure to
switch VSA ® on again. We do not recommend driving
your vehicle with the VSA ® system switched off.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after turning the power
system on or while driving. This is normal.

uuWhen Driving uHigh Voltage Battery
Driving
High Voltage Battery
The High Voltage battery gradually discharges even if the vehicle is not in use. As a
result, if your vehicle is parked for an extended period of time, the battery charge
level will become low. Extended periods of ti me at a low state of charge will shorten
battery life. To maintain the battery state of charge, drive your vehicle for more than
30 minutes at least once every three months.
Extreme high temperatures can affect the battery life. You can minimize the effects
by parking the vehicle in the shade during the summer.1 High Voltage Battery
Be careful not to let the High Voltage battery drain
too much. If the battery level becomes close to zero,
it will make it impossible to start the engine.

Braking
Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can manu ally or automatically release it.
■To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
position the power mode is in.
Pull the electric parking brake switch up gently
and securely. u The indicator in the switch comes on.
u The parking brake and brake system
indicator (red) comes on.
■To release
The power mode must be in ON in order to
release the electric parking brake.
1. Depress the brake pedal.
2. Press the electric parking brake switch.
u The indicator in the switch goes off.
u The parking brake and brake system
indicator (red) goes off.
Manually releasing the parking brake using
the switch helps your vehicle to start slowly
and smoothly when facing downhill on steep
hills.
■Parking Brake1 Brake System
When you depress the brak e pedal, you may hear a
whirring sound from the engine compartment. This is
because the brake system is in operation, and it is
normal.
1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parki ng brake. This is normal.
The brake pedal may slightly move due to the electric
parking brake system opera tion when you apply or
release the parking br ake. This is normal.
You cannot apply or release the parking brake if the
12-volt battery goes dead. 2 If the 12-Volt Battery Is Dead P. 579
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the electric servo brake
system until the vehicle comes to a stop. The
electric parking brake then applies, and the
switch should be released.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you can.
The electronic brake distribu tion (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pu mp the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Depress the brake
pedal and keep holding the pedal firmly do wn. On dry pavement, you will need to
press on the brake pedal very hard before th e ABS activates. However, you may feel
the ABS activate immediately if you are trying to stop on snow or ice.
ABS may activate when you depres s the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surf aces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use a tire of
the incorrect size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system. While normal
braking will not be affected, there is a possibility that
the ABS will not be opera ting. Have your vehicle
checked by a dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lockup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
•You are driving on rough or uneven road surfaces,
such as gravel or snow.
•The tires are equipped with tire chains*.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
power system has been started while vehicle
accelerates.
•Brake pedal and/or the vehicle body vibration when
ABS activates.
These vibrations and sou nds are normal to ABS
systems and are no cause for concern.

Heat from the exhaust can cause a fire.
After shutting off the engi ne, you may hear certain
noises coming from the vehicle. Here’s the lowdown:
•Noise from Under Vehicle: This noise is caused by
the vacuum pump inside the fuel evaporation
leakage check module (ELCM).
Depending on conditions, the pump will come on for
about 15 minutes about 5 to 10 hours after engine
shutoff. This noise is ju st normal vehicle operation
and don’t indicate a vehicle problem.

Refueling
Fuel Information
■Fuel recommendation
Use of a lower octane gasoline can cause a persistent, heavy metallic knocking noise
that can lead to engine damage.
■Top tier detergent gasoline
Because the level of detergency and additives in gasoline vary in the market, Honda
endorses the use of “TOP TIER Deterg ent Gasoline” where available to help
maintain the performance and reliability of your vehicle. TOP TIER Detergent
Gasoline meets a new gasoline standard join tly established by leading automotive
manufacturers to meet the need s of today’s advanced engines.
Qualifying gasoline retailers will, in most ca ses, identify their gasoline as having met
“TOP TIER Detergent Gasoline” standards at the retail location. This fuel is
guaranteed to contain the proper level of detergent additives and be free of metallic
additives. The proper level of detergent additives, and absence of harmful metallic
additives in gasoline, help avoid buildup of deposits in your engine and emission
control system.
For further important fuel-rel ated information for your vehicle, or on information on
gasoline that does not contain MMT, visit www.hondacars.com. In Canada, visit
www.honda.ca for additional information on gasoline. For more information on top
tier gasoline, visit www.toptiergas.com .
■Fuel tank capacity: 12.81 US gal (48.5 L)
Unleaded gasoline, pump octane number 87 or higher
1Fuel Information
NOTICE
We recommend quality ga soline containing
detergent additives that help prevent fuel system and
engine deposits. In addition, in order to maintain
good performance, fuel economy, and emissions
control, we strongly reco mmend the use of gasoline
that does NOT contain harmful manganese-based
fuel additives such as MMT, if such gasoline is
available.
Use of gasoline with these additives may adversely
affect performance, a nd cause the malfunction
indicator lamp on your inst rument panel to come on.
If this happens, contact a dealer for service.
Some gasoline today is blended with oxygenates such
as ethanol. Your vehicle is designed to operate on
oxygenated gasoline containing up to 15% ethanol
by volume. Do not use gaso line containing methanol.
If you notice any undesira ble operating symptoms, try
another service station or sw itch to another brand of
gasoline.

Fuel Economy and CO2 Emissions
Improving Fuel Economy and Reducing CO2
Emissions
Achieving fuel economy and reducing CO2 emissions is dependent on several
factors, including driving conditions, load weight, idling time, driving habits, and
vehicle condition. Depending on these and other factors, you may not achieve the
rated fuel economy of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accord ance with the messages displayed on the
driver information interface.
• Use engine oil with the viscosity recommended.
2 Recommended Engine Oil P. 523
•Maintain the specified tire pressure.
• Do not load the vehicle with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside
adds weight and increases wind resistance.
■Maintenance and Fuel Economy
1Improving Fuel Economy and Reducing CO2 Emissions
Direct calculation is the recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a simulated test.
For more information on how this test is performed,
please visit https://www.nrcan.gc.ca and search for
“fuel consumption testing” in the search field at the
top of the page.
