When the system has calculated
that oil life has been diminished,
it indicates that an oil change is
necessary. A CHANGE ENGINE
OIL message comes on. Change
the oil as soon as possible within
the next 1 000 km (600 mi). It is
possible that, if driving under the
best conditions, the oil life system
might indicate that an oil change is
not necessary for up to a year.
The engine oil and filter must be
changed at least once a year and,
at this time, the system must be
reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Press the TRIP button sothe OIL LIFE percentage is
displayed.
2. Press RESET and hold for two seconds. OIL LIFE
REMAINING 100% will
appear.
If the CHANGE ENGINE OIL
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check
the transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as soon
as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer. Contact the
dealer for additional information or
the procedure can be found in the
service manual. To purchase a
service manual, see Service
Publications Ordering Information
on page 13‑18.

Notice:Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11‑12.
Change the fluid and filter at the
intervals listed in Maintenance
Schedule on page 11‑3, and
be sure to use the fluid listed in
Recommended Fluids and
Lubricants on page 11‑12.
Manual Transmission
Fluid
It is not necessary to check the
manual transmission fluid level.
A transmission fluid leak is the
only reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as soon
as possible. See Recommended
Fluids and Lubricants on page 11‑12
for the proper fluid to use.
Hydraulic Clutch
It is not necessary to regularly
check clutch fluid unless you
suspect there is a leak in the
system. Adding fluid will not correct
a leak. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
When to Check and What
to Use
The hydraulic clutch fluid reservoir
cap has this symbol on it. See
Engine Compartment Overview on
page 10‑8 for reservoir location. Refer to the Maintenance
Schedule for the proper fluid to use.
See
Recommended Fluids and
Lubricants on page 11‑12. The fluid
requires changing every two years.
See Maintenance Schedule on
page 11‑3.
How to Check and Add Fluid
Visually check the clutch fluid
reservoir to make sure the fluid level
is at the MIN (minimum) line on the
side of the reservoir. The hydraulic
clutch fluid system should be closed
and sealed.
Do not remove the cap to check
the fluid level or to top‐off the fluid
level. Remove the cap only when
necessary to add the proper fluid
until the level reaches the MIN line.

Vehicle Care 10-41
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
If the level is below the bottom of
the fill plug hole, some lubricant will
need to be added. Add enough
lubricant to raise the level to the
bottom of the fill plug hole.
What to Use
To add lubricant when the level is
low or to completely refill after
draining, seeRecommended Fluids
and Lubricants on page 11‑12.
Then fill to the bottom of the fill plug
hole with the required lubricant.

Tire Designations
Tire Size
The following is an example
of a typical passenger vehicle
tire size.
(A) Passenger (P‐Metric) Tire:
The United States version
of a metric tire sizing system.
The letter P as the first
character in the tire size
means a passenger vehicle
tire engineered to standards
set by the U.S. Tire and Rim
Association.
(B) Tire Width
:The three‐digit
number indicates the tire
section width in millimeters
from sidewall to sidewall. (C) Aspect Ratio
:A two‐digit
number that indicates the tire
height‐to‐width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(D) Construction Code
:
A letter code is used to indicate
the type of ply construction in
the tire. The letter R means
radial ply construction; the
letter D means diagonal or
bias ply construction; and the
letter B means belted‐bias ply
construction.
(E) Rim Diameter
:Diameter of
the wheel in inches.
(F) Service Description
:
These characters represent
the load index and speed rating
of the tire. The load index
represents the load carrying capacity a tire is certified to
carry. The speed rating is the
maximum speed a tire is
certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch
of the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight
:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
steering, power brakes, power
windows, power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire's height to its width.

Jump Starting
For more information about the
vehicle battery, seeBattery on
page 10‑40.
If your battery has run down, you
may want to use another vehicle
and some jumper cables to start
your vehicle. Be sure to use the
following steps to do it safely.
{WARNING
Batteries can hurt you. They can
be dangerous because:
.They contain acid that can
burn you.
.They contain gas that can
explode or ignite.
.They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you. Notice:
If you try to start your
vehicle by pushing or pulling it,
you could damage your vehicle.
Do not push or pull your vehicle
to start it; instead, use the jump
starting procedure in this manual
to start your vehicle when the
battery has run down.
1. Check the other vehicle. It must
have a 12-volt battery with a
negative ground system.
Notice: Only use a vehicle that
has a 12-volt system with a
negative ground for jump
starting. If the other vehicle does
not have a 12-volt system with a
negative ground, both vehicles
can be damaged.
2. Get the vehicles close enough so the jumper cables can reach,
but be sure the vehicles are not
touching each other. If they are,
it could cause a ground
connection you do not want.
You would not be able to start
your vehicle, and the bad
grounding could damage the
electrical systems. To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking
brakes.
Notice: If any accessories are left
on or plugged in during the jump
starting procedure, they could be
damaged. The repairs would
not be covered by the vehicle
warranty. Whenever possible,
turn off or unplug all accessories
on either vehicle when jump
starting the vehicle.
3. Turn off the ignition on both vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlet. Turn off the radio
and all lamps that are not
needed. This will avoid sparks
and help save both batteries.
And it could save the radio!
