The f ollowing f actors can lower your
vehicle’s f uel economy:
Aggressive driving (hard
acceleration and braking)
Excessive idling, accelerating and
braking in stop-and-go traf f ic
Cold engine operation (engines
are more efficient when
warmed up)
Driving with a heavy load or the
air conditioner running
Improperly inf lated tires
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
inf ormation display (see on page ).For example:
Rapid
acceleration, abrupt cornering,
and hard braking increase
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible. Aerodynamic drag has a big ef f ect
on f uel economy at speeds above
45 mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
Idling
results in 0 miles per gallon (0 kms
per liter).
An underinf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
It puts a heavier
load on the engine, increasing
In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your
fuel economy.

The added weight, length, and
height of a trailer will affect your
vehicle’s handling and performance,
so driving with a trailer requires
some special driving skills
and techniques.
The vehicle has been properly
serviced, and the tires, brakes,
suspension, cooling system,
and lights are in good
operating condition.
The trailer has been properly
serviced and is in good condition.
All weights and loads are
within limits.
Thehitch,safetychains,andany
other attachments are secure.
Allitemsonandinthetrailerare
properly secured and cannot shif t
while you drive.
When preparing to tow, and
before driving away, be sure to
check the following:
Towing performance can be
affected by high altitude, high
temperature, or when climbing
steep grades. Therefore,
premium fuel (premium
unleaded gasoline
with pump octane number
of 91 or higher)
is recommended when
towing more than
3,500 lbs (1,590 kg). The trailer tires and spare are
in good condition and
inflated as recommended by
the trailer maker. Your vehicle tires and spare
are in good condition and
properly inflated. The lights and brakes on your
vehicle and the trailer are
working properly.Foryoursafetyandthesafetyof

If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and from
diesel-powered vehicles, replace every 15,000 miles

If you drive regularly in very high temperatures
(over 110°F, 43°C), in very low temperatures
(under 20°F, 29°C), or towing a trailer, replace every
60,000 miles (U.S.)/100,000 km (Canada).
Driving in mountainous terrain at very low speeds,
towing a trailer or driving when fully loaded causes
more mechanical (shear) stress and fluid deterioration.
This requires differential fluid changes more frequently
than recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles
(12,000 km), then every 15,000 miles (24,000 km).

Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort.Underinf lated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,are
more prone to damage f rom road
hazards, and wear unevenly. Even though your vehicle is
equipped with TPMS, we
recommend that you visually check
your tires every day. If you think a
tire might be low, check it
immediately with a tire gauge.
Use a gauge to measure the air
pressure in each tire at least once a
month. Even tires that are in good
condition may lose 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime.
Check the air pressures when the
tires are cold. This means the
vehicle has been parked f or at least 3
hours, or driven less than 1 mile (1.6
km). Add or release air, if needed, to
match the recommended cold tire
pressures on page . If you check air pressures when the
tires are hot (driven for several
miles/kilometers), you will see
readings 4 to 6 psi (30 to 40 kPa, 0.
3 to 0.4 kgf/cm ) higher than the
cold readings. This is normal.
Do not let air out to match the
recommended cold air pressure.
The tire will be underinflated.
You should get your own tire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier for you to tell if a
pressure loss is due to a tire
problem and not due to a
variation between gauges.
While tubeless tires have some
ability to self-seal if they are
punctured, you should look
closely for punctures if a tire
starts losing pressure.
The tire pressure monitoring system
(TPMS) warns you when a tire
pressure is low. See page or
f or more inf ormation. 276

If this indicator comes on
while driving, it means one
of the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage.
If you have recently ref ueled your
vehicle, the indicator coming on
could be due to a loose or missing
f uel f ill cap. Tighten the cap until it
clicks at least once. Tightening the
cap will not turn the indicator of f
immediately; it can take several days
of normal driving. If the indicator comes on
repeatedly, even though it may
turn off as you continue driving,
have your vehicle checked by the
dealer as soon as possible.
The indicator may also come on with
the ‘‘D’’ indicator.
You will also see a ‘‘CHECK
FUEL CAP’’ message on the
information display.
You will also see a ‘‘TIGHTEN FUEL
CAP’’ message on the multi-
inf ormation display.
You will also see a ‘‘CHECK
EMISSION SYSTEM’’ message on
the multi-information display (see

Technical Inf ormation

The exhaust emissions controls
include four systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way
catalytic converter. These four
systems work together to control
the engine’s combustion and
minimize the amount of HC, CO,
and NOx that come out the tailpipe.
The exhaust emissions control
systems are separate from the
crankcase and evaporative
emissions control systems.
The PGM-FI system uses
sequential multiport fuel injection.
It has three subsystems: air intake,
engine control, and fuel control.
The powertrain control module
(PCM) uses various sensors to
determine how much air is going
into the engine. It then controls
how much fuel to inject under
all operating conditions.This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust gas recirculation
(EGR) system takes some of the
exhaust gas and routes it back
into the intake manifold. Adding
exhaust gas to the air/fuel mixture
reduces the amount of NOx
produced when the fuel is burned.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor.
The emissions control systems are
covered by warranties separate
from the rest of your vehicle.
Read your warranty manual for
more information. The emissions control systems are
designed and certif ied to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Honda replacement parts or their
equivalent f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.
