Avoiding Trouble
• Check Out Your Vehicle before you leave the pavement and make sure that all
scheduled maintenance has been comple ted. Pay special attention to the
condition of the tires, an d check the tire pressures.
• Remember the route you choose presents limits (too steep or bumpy), you have
limits (driving skill and comfort), and your ve hicle has limits (traction, stability, and
power). Failing to recognize these limits will likely put you and your passengers in
a hazardous situation.
• Accelerating and Braking should be done slowly and gradually. Trying to start
or stop too fast can cause a loss of traction and you could lose control.
• Avoiding Obstacles and Debris in the road reduces the likelihood of a rollover
or damage to your suspension or other components.
• Driving on Slopes increases your risk of a rollover, particularly if you attempt to
drive across a slope that is too steep. Going straight up or down a slope is usually
the safest. If you can’t clearly see all cond itions or obstacles on a slope, walk it
before you drive it. If there is any doubt whether you can safely pass, don’t try it.
Find another route. If you get stuck when climbing, do not try to turn around.
Back down slowly following the same route you took up the hill.
• Crossing a Stream - Avoid driving through deep water. If you encounter water
in your route (a small stream or large pu ddle, for example), evaluate it carefully
before going ahead. Make sure it is shallow, flowing slowly, and has firm ground
underneath. If you are not sure of the depth or the ground, turn around and find
another route. Driving through deep water can also damage your vehicle. When
driving in water that reaches around half of the wheel height, the water can get
into the transmission and differential, diluting the lubricant and causing an
eventual failure. It can also wash th e grease out of the wheel bearings.
• If You Get Stuck, carefully go in the direction that you think will get you
unstuck. Do not spin the tires as this will only make things worse and could
damage the transmission. If you are unable to free yourself, your vehicle will need
to be towed. Front and rear tow hooks are provided for this purpose.

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver 's responsibility to maintain
correct tire pressure, even if un der-inflation has not reached the
level to trigger illumina tion of the TPMS low ti re pressure telltale.
Your vehicle has also been eq uipped with a TPMS malfunction
indicator to indicate when the sy stem is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the system detects a malfunction, the
telltale will flash fo r approximately one minute and then remain
continuously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

■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 obstacles, as well as providing assistance
with braking.
If the only rear sensors are turned off using the parking sensor system, the assistive
braking will not work when reversing.

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. 613
•Maintain the specified tire pressure.
• Do not load the vehicl e 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

consumption testing” in the search field at the top of

Before Performing Maintenance
Inspection and Maintenance
For your safety, perform all listed inspections and maintenance to keep your vehicle
in good condition. If you become aware of an y abnormality (noise, smell, insufficient
brake fluid, oil residue on the ground, etc.), have your vehicle inspected by a dealer.
(Note, however, that service at a dealer is not mandatory to keep your warranties in
effect.)
■Routine inspections
Perform inspections before long distance tri ps, when washing the vehicle, or when
refueling.
2 Maintenance P. 37
■Periodic inspections
• Check the brake fluid level monthly.
2 Checking the Brake Fluid P. 621
•Check the tire pressure monthly. Examin e the tread for wear and foreign objects.
2Checking and Maintaining Tires P. 631
•Check the operation of the exterior lights monthly.
2 Replacing Light Bulbs P. 623
•Check the condition of the wiper bl ades at least every six months.
2Checking and Maintaining Wiper Blades P. 627
■Types of Inspection and Maintenance
1Inspection and Maintenance
Maintenance, replacement, or repair of
emissions control devices and systems may be
done by any automotive repair establishment or
individuals using parts that are “certified” to
EPA standards.
According to state and fede ral regulations, failure to
perform maintenance on the maintenance main
items marked with # will not void your emissions
warranties. However, all ma intenance services should
be performed in accordan ce with the intervals
indicated by the driver information interface.
2 Maintenance Service Items P. 607
If you want to perform complex maintenance tasks
that require more skills a nd tools, you can purchase a
subscription to the Service Express website at
www.techinfo.honda.com .
2 Authorized Manuals P. 704
If you want to perform ma intenance yourself, make
sure that you have the necessary tools and skills first.
After performing maintenanc e, update the records in
the separate maintenance booklet.

Safety When Performing Maintenance
Some of the most important safety pr ecautions 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 12-volt battery, all High Volt age system, 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 clothing when working with the 12-volt
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.
