Wheel Replacement
Considerations
Damaged wheels must be
replaced. For example, replace
wheels if they are bent, cracked or
heavily rusted, or if wheel nuts
often become loose. Also replace
wheels that leak air (except some
aluminum wheels that can be
repaired). See your Honda dealer.
Do not use bent wheels that have
been straightened, and do not use
tubes in leaking wheels designed
for tubeless tires. Such wheels
may have structural damage and
could fail without warning.
Maximum loads, maximum
inflation pressures, wheel
identification codes, and wheel
sizes are stamped on each wheel.
Service-tested and approvedwheels are available from your
Honda dealer.
When obtaining wheels for any
reason from any other source, the
replacement wheels should be
equal in load capacity, inflation
pressure capacity, diameter, width,
offset and mounting configuration
to those originally installed on
your vehicle. A wheel of the
wrong size or type may adversely
affect load carrying capacity,
wheel and bearing life, brake
cooling, speedometer/odometer
calibration, stopping ability,
headlight aim, bumper height,
vehicle ground clearance, and tire
or tire chain clearance to the body
and chassis. Replacement with
used wheels is not advised: They
may have been subjected to harsh
treatment or very high mileage and
could fail without warning.
Installing wheels and/or tires that
have a higher load carrying limit
than those that originally came on
your vehicle does not increase the
GAWR or GVWR of the vehicle.

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.

182Driving Tips
There are no provisions in your
vehicle to tap into its hydraulic
braking system. Any attempt to
attach the trailer
’s brakes to your
vehicle’ s hydraulic braking
system, no matter how successful
it may seem, will lower braking
effectiveness and create a
potential hazard.
Equipment Check
Before operating your vehicle,
check all safety equipment to
ensure safe operation. Be sure
your vehicle is properly serviced
to avoid mechanical failure.
Check that your vehicle remains
level when the loaded or unloaded
trailer is hitched. Do not drive if
the rear end of your vehicle is
abnormally higher or lower.
Check for proper tongue weight,
overload, improper weight distribution, worn suspension, or
other possible causes.
Make sure the trailer load is
properly positioned and secured
so its does not shift around while
driving.
Check if your rearview mirrors
comply with federal, state and
local regulations. If not, confirm
the proper mirrors required for
towing and have them installed.
Perform an equipment check of
all braking, lighting and safety
equipment to ensure they are
working properly.
Your safety depends on proper
operation and installation of
equipment. Never operate a
vehicle with faulty equipment.
Standard on 4WD models
The limited slip differential is
designed to improve traction by
limiting wheelspin. If one rear
wheel begins to spin on a slippery
surface, the limited slip
differential will automatically
transmit driving force to the other
rear wheel.

8. Turn the jack handle
clockwise with a slow, smooth
motion to raise the vehicle so
the inflated spare tire will
clear the surface.
9. Remove the wheel nuts and the wheel.
10. Install the wheel and replace the wheel nuts with the
cone-shaped end toward the
wheel, then hand-tighten each
nut. The wheel must be seated
on the hub.
11. Lower the vehicle by turning the jack handle counter-
clockwise, then fully tighten
the wheel nuts in a crisscross
sequence by turning the
wrench clockwise. Have the
wheel nut torque checked at
the nearest automotive service
facility.
87 lb-ft (118 N·m) 12. Stow the jacking tools and flat
tire in their proper locations.
EX model
Use the screwdriver to remove the
center cap from the wheel before
stowing the flat tire.
Loose items can fly around the
interior in a crash and could
seriously injure the occupants.
Store the wheel, jack, and
tools securely before driving.
The jack is stored in a
compartment on the driver ’s side
rear wheel panel.
To remove the jack from its
compartment, turn the handle
counterclockwise. Disconnect the
hold-down strap.

standards, some areas of the United
States and Canada use oxygenated
fuels to help reduce emissions.
If you use an oxygenated fuel, be
sure it is unleaded and meets the
minimum octane rating requirement.
Before using an oxygenated fuel,
try to confirm the fuel’
s contents.
Some states/provinces require this
information to be posted on the
pump.
The following are the EPA-approved
percentages of oxygenates:
ETHANOL (ethyl or grain alcohol).
You may use gasoline containing up
to 10% ethanol by volume. Gasoline
containing ethanol may be marketed
under the name “Gasohol.”
MTBE (Methyl Tertiary Butyl
Ether). You may use gasoline
containing up to 15%
MTBE by
volume.
METHANOL (methyl or wood
alcohol). Your vehicle was not
designed to use fuel that contains
methanol. Methanol can corrode
metal parts in the fuel system, and
also damage plastic and rubber
components. This damage would not
be covered by your warranties.
If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
Fuel system damage or performance
problems resulting from the use of
an oxygenated fuel containing
more than the percentages of
oxygenates given above are not
covered under warranty. Regularly maintaining your
vehicle is the best way to protect
your investment. Proper
maintenance is essential to your
safety and the safety of your
passengers. It will also reward
you with more economical,
trouble-free driving and help
reduce air pollution.
Improperly maintaining this
vehicle or failing to correct a
problem before driving can
cause a crash in which you
can be seriously hurt or killed.
Always follow the inspection
and maintenance
recommendations and
schedules in this owner’s
manual.
