distances will be longer and
vehicle control more limited.
While driving on a surface with
reduced traction, avoid maneuvers
involving sudden steering,
acceleration, or braking (including
engine braking due to shifting to
lower gear), that could cause the
tires to skid.
Drivers may not realize the
surface is slippery until the
vehicle is skidding.
Learn to recognize warning
clues—such as enough water or
ice on the road to make a
“mirrored surface”—and slow
down when there is any doubt.
Also see “Traction” under “Tires”
in this section.
Rapid slowing down or
speeding-up can cause loss
of control on slippery
surfaces. If you crash, you
can be injured.
Use extra care when driving
on slippery surfaces.
To safely operate your vehicle,
your tires must be the proper type
and size, in good condition with
adequate tread, and correctly
inflated. The following pages give
more detailed information on how
and when to check air pressure,
how to inspect your tires for
damage and wear, and what to do
when your tires need to be
replaced.
Using tires that are excessively
worn or improperly inflated can
cause a crash in which you
can be seriously hurt or killed.
Follow all instructions in this
owner’s manual regarding tire
inflation and maintenance.

indicator in three or more places
around the tire.
Maintenance
In addition to proper inflation,
correct wheel alignment helps to
decrease tire wear. You should get
your vehicle’
s suspension parts
inspected often, and aligned when
needed.
The tires were properly balanced
at the factory. They may need to
be rebalanced at some time before
they are worn out. Have your
dealer check the tires if you feel a
consistent vibration while driving.
A tire should always be
rebalanced if it is removed from
the wheel for repair.
Make sure the installer balances
the wheels when you have new
tires installed. This increases riding comfort and tire life. Your
vehicle’
s original tires were
dynamic or “spin” balanced at the
factory. For best results, have the
installer perform a dynamic
balance.
Tire Rotation
To help increase tire life and
distribute wear more evenly, you
should have the tires rotated every
7,500 miles (12,000 km).
FRONT

Move the tires to the positions
shown in the diagram each time
they are rotated.
Replacing Tires and Wheels
The tires that came with your
vehicle were selected to match its
performance capabilities while
providing the best combination of
handling, ride comfort, and long
life. You should replace them with
radial tires of the same size, load
range, speed rating, and maximum
cold tire pressure rating (as shown
on the tire’ s sidewall). Mixing
radial and bias-ply tires on your
vehicle can reduce its braking
ability, traction, and steering
accuracy.

170Driving Tips
Driving for Best Fuel
Economy
How, where, and when you drive
all affect how many miles/
kilometers you can get from a
gallon/liter of fuel. The careful
attention you give your vehicle as
far as maintenance and repairs
will also help fuel economy.
Fuel Selection
Use only unleaded gasoline
meeting federal government
regulations. The federal
government specifies the
minimum octane rating number of
unleaded gasoline. Unleaded
gasoline must be used for proper
emissions control system
operation. It will also minimize
spark plug fouling. The use of
leaded gasoline can damage the
emissions control system andcould result in loss of warranty
coverage.
“Jackrabbit” Starts
You can save fuel (and prolong
engine and tire life) by avoiding
fast starts away from lights and
stop signs.
Stop-and-Go Driving
Frequent stop-and-go driving
during a trip will cut down on
your miles per gallon (kilometers
per liter). Plan even your short
shopping trips to take advantage
of through streets to avoid traffic
lights. Pace your driving to avoid
unplanned stops.
Excessive Idling
An idling engine uses fuel, too. If
you’re faced with more than a few
minutes wait and you
’re not intraffic, it is better to turn off the
key and start the engine again
later.
Repetitive Harsh Stopping
Harsh stops can also waste fuel;
instead of moving the vehicle, the
energy is wasted as heat in
braking. Energy in the form of
fuel is also needed to accelerate
back to driving speed.
Lubricants
A well-lubricated vehicle means
less friction between moving
parts. This manual lists the proper
lubrication intervals in the
“Care
and Maintenance ” section.
Air Cleaner
Your vehicle gets its power from a
mixture of fuel and air. The air is
taken into the engine through the
Fuel Economy

171Driving Tips
air cleaner, so it’
s important to
replace the air cleaner filter at
required intervals. See “Care and
Maintenance.” A dirty air cleaner
filter reduces engine performance
and can waste fuel.
Air Conditioning
Turn off the air conditioning when
it is not needed. The air
conditioning compressor is not on
in this position and the reduced
engine load can improve fuel
economy.
Tuned Engine
An engine that is properly
maintained will provide better
fuel economy than one that is not.
One misfiring spark plug will cut
fuel economy significantly, and
will make a difference in the
amount of pollution emitted from
your vehicle. Excessive Weight
Fuel economy is related to the
work the engine must do. The
heavier the load, the more fuel it
takes to run your vehicle. Keep
weight to a minimum by removing
unnecessary luggage or cargo.
Tire Inflation
Underinflation not only causes
needless tire wear but can also
waste fuel. It’
s a good idea to
check tire pressure often and keep
your tires inflated to the pressures
shown on the tire placard located
on the driver ’s doorjamb. Wheel Alignment
Improper alignment will cause the
front tires to roll at an angle that
will result in faster tire wear. It
takes power to overcome this
improper alignment, which, in
turn, wastes fuel.
Use of 4-Wheel Drive
In normal driving, put the
4WD-2WD switch in the 2WD
position.

172 Driving Tips
The
three-way catalytic converter
is an emissions control device
added to the exhaust system to
reduce exhaust gas pollutants. The
converter contains a ceramic
material coated with noble metal
catalysts. To prevent
contamination of the catalysts,
unleaded gasoline must be used.
Unleaded gasoline also reduces
combustion chamber deposits and
exhaust system corrosion.
The three-way catalytic converter
requires the use of unleaded
gasoline. Use of leaded gasoline
will cause the converter to lose its
effectiveness.
To Help Prevent Damage
1. Keep your engine properly
maintained. Engine
malfunctions involving the electrical,
electronic fuel
injection or ignition systems
may result in unusually high
converter and exhaust system
temperatures. Do not keep
driving your vehicle if you
detect engine misfire,
noticeable loss of performance,
or other unusual operating
conditions. Have it serviced
promptly. A properly
maintained engine will
minimize malfunctions that
could damage the converter. It
will also help provide good
emissions control and fuel
economy. (See the
Maintenance Schedule on page
204 for info rmation on
inspecting and maintaining the
engine, exhaust system and
other components.) 2. Do not push or tow your
vehicle to start it. This could
damage the converter.
3. Do not park your vehicle over high grass, dry leaves or other
combustible materials. The
catalytic converter gets very
hot and could set fire to these
materials.

Follow the recommendations in
this manual and ask your Honda
dealer for further details before
you tow a trailer with your
Passport.
Towing a trailer affects vehicle
maintenance requirements due
to the additional load. More
frequent maintenance intervals
will be required to assure
continued satisfaction with
your vehicle. Consult your
Honda dealer for recommended
maintenance and service.
The gross trailer weight (trailer
weight plus cargo load) must
never exceed 4,500 lb.
Additional equipment will be
required, depending on the
specific model/load combination.
See “Trailer Hitches” in this
section.
Exceeding the weight limit will
cause damage to your vehicle and
possibly result in personal injury.
•The Gross Vehicle Weight
Rating (
GVWR) is the
combined weight of the
unloaded vehicle, passengers,
cargo, trailer hitch, trailer
tongue load, and optional
equipment. This value is
indicated on the
F.M.V.S.S.
Certification Label on the
driver ’ s doorjamb.
•The Gross Combined Weight
Rating (
GCWR) equals the
combined weight of your
vehicle (including passengers
and cargo) plus the total trailer
load. The following limits
apply.
2WD: 8,700 lb
4WD: 8,950 lb
•The Gross Axle Weight Rating
(
GAWR) is also indicated on
the Certification Label. The
load on either the front or rear
axle resulting from distribution
of the gross vehicle weight on
both axles must not exceed the
values listed. Remember to
account for additional
equipment and tongue load.
