Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing
its job. See your dealer/retailer to have it repaired. Torn
or frayed safety belts may not protect you in a crash.
They can rip apart under impact forces. If a belt is torn
or frayed, get a new one right away.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders on page 3-35for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 5-109.
Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 3-36for more information.
Notice:If an airbag covering is damaged, opened,
or broken, the airbag may not work properly.
Do not open or break the airbag coverings. If there
are any opened or broken airbag covers, have
the airbag covering and/or airbag module replaced.
For the location of the airbag modules, seeWhat
Makes an Airbag Inflate? on page 1-65. See your
dealer/retailer for service.
1-74

Oil Pressure Light
For vehicles with an oil
pressure light, if there
is a problem with the oil,
the light may stay on
after the engine is started,
or comes on while
driving.
This light indicates that oil is not going through the engine
quickly enough to keep it lubricated. The engine could be
low on oil or could have some other oil problem. Have the
vehicle serviced by your dealer/retailer.
The oil light could also come on in the following
situations:
The light comes on briey when the ignition is
turned on to show that it is working properly.
If it does not come on with the ignition on, there
may be a problem with the fuse or bulb. Have the
vehicle serviced by your dealer/retailer.
Sometimes when the engine is idling at a stop, a
chime sounds and the light may blink on and off.
This is normal.
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
3-46

Engine Oil Pressure Gage
For vehicles with an engine oil pressure gage. It shows
the engine oil pressure in psi (pounds per square inch)
when the engine is running. Canadian vehicles indicate
pressure in kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but if readings are outside
the normal operating range, the oil pressure light will
come on. SeeOil Pressure Light on page 3-46for more
information.A reading outside the normal operating range may be
caused by a dangerously low oil level or some other
problem causing low oil pressure. Oil should be
checked as soon as possible. See Oil pressure Low
Stop Engine underDIC Warnings and Messages
on page 3-58andEngine Oil on page 5-18.
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance can
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil. United States

Parking on Hills
{CAUTION:
Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can
be damaged. When possible, always park the rig
on a at surface.
If parking the rig on a hill:
1. Press the brake pedal, but if the vehicle has an
automatic transmission, do not shift into P (Park)
yet. Turn the wheels into the curb if facing downhill
or into traffic if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the brake pedal. For vehicles with an
automatic transmission, apply the parking brake and
shift into P (Park). For vehicles with a manual
transmission, apply the parking brake, place the
transmission in 1 (First) and turn the ignition to
OFF/LOCK.
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
Start the engine
Shift into a gear
Release the parking brake
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. See this manual’s Maintenance Schedule or Index
for more information. Things that are especially important
in trailer operation are automatic transmission uid,
engine oil, axle lubricant, belts, cooling system and brake
system. It is a good idea to inspect these before and
during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-37.
4-34

Hydraulic Clutch
It is not necessary to regularly check clutch uid unless
you suspect there is a leak in the system. Adding
uid will not correct a leak. A uid loss in this system
could indicate a problem. Have the system inspected
and repaired.
When to Check and What to Use
The hydraulic clutch uid
reservoir cap has this
symbol on it. SeeEngine
Compartment Overview
on page 5-14for reservoir
location.Refer to the Maintenance Schedule for the proper
uid to use. SeeRecommended Fluids and Lubricants
on page 6-14. The uid requires changing every
two years. SeeAdditional Required Services on
page 6-6.
How to Check and Add Fluid
Visually check the clutch uid reservoir to make sure
the uid level is at the MIN (Minimum) line on the side
of the reservoir. The hydraulic clutch uid system should
be kept closed and sealed. Do not remove the cap to
check the uid level or to top-off the uid level. Remove
the cap only when necessary to add the proper uid
until the level reaches the MIN line.

Using the Maintenance Schedule
We want to help keep this vehicle in good working
condition. But we do not know exactly how you will
drive it. You might drive very short distances only a
few times a week. Or you might drive long distances
all the time in very hot, dusty weather. You might
use the vehicle in making deliveries. Or you might
drive it to work, to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You might need
more frequent checks and replacements. So please read
the following and note how you drive. If you have any
questions on how to keep the vehicle in good condition,
see your dealer/retailer.
This schedule is for vehicles that:
carry passengers and cargo within recommended
limits on the Tire and Loading Information label.
SeeLoading the Vehicle on page 4-20.
are driven on reasonable road surfaces within legal
driving limits.
use the recommended fuel. SeeGasoline Octane
on page 5-6.
The services inScheduled Maintenance on page 6-4
should be performed when indicated. SeeAdditional
Required Services on page 6-6andMaintenance
Footnotes on page 6-8for further information.
{CAUTION:
Performing maintenance work on a vehicle can be
dangerous. In trying to do some jobs, you can be
seriously injured. Do your own maintenance work
only if you have the required know-how and the
proper tools and equipment for the job. If you have
any doubt, see your dealer/retailer to have a
qualied technician do the work. SeeDoing
Your Own Service Work on page 5-4.
Some maintenance services can be complex. So, unless
you are technically qualied and have the necessary
equipment, have your dealer/retailer do these jobs.
When you go to your dealer/retailer for service, trained
and supported service technicians will perform the
work using genuine parts.
To purchase service information, seeService
Publications Ordering Information on page 7-15.

The proper replacement parts, uids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 6-14andMaintenance Replacement Parts
on page 6-16. When the vehicle is serviced, make sure
these are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of genuine
parts from your dealer/retailer.
Scheduled Maintenance
To maintain the ride, handling, and performance
of this vehicle, it is important that the rst tire rotation
service be performed when the vehicle has 5,000
to 8,000 miles (8 000 to 13 000 km). Check tires for
ination pressures and wear. SeeTires on page 5-61.
Rotate tires. SeeTire Inspection and Rotation on
page 5-76and “Tire Wear Inspection” inAt Least
Once a Month on page 6-11.When the Change Engine Oil Soon message displays in
the Driver Information Center (DIC), service is required
for the vehicle. Have the vehicle serviced as soon
as possible within the next 600 miles (1 000 km).
It is possible that, if driving under the best conditions,
the engine oil life system may not indicate that
vehicle service is necessary for over a year. However,
the engine oil and lter must be changed at least once
a year and at this time the system must be reset.
Your dealer/retailer has trained service technicians
who will perform this work using genuine parts and
reset the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km)
since the last service. Remember to reset the oil life
system whenever the oil is changed. SeeEngine Oil Life
System on page 5-21for information on the Engine
Oil Life System and resetting the system.
