Power Steering Fluid
When to Check Power Steering Fluid
The power steering fluid reservoir is located toward
the front of the engine compartment on the
driver’s side of the vehicle. SeeEngine
Compartment Overview on page 258for reservoir
location.
It is not necessary to regularly check power
steering fluid unless you suspect there is a leak in
the system or you hear an unusual noise.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
How to Check Power Steering Fluid
Turn the key off and let the engine compartment
cool down. Then check the fluid level.The level should be between the MIN (B) and
MAX (A) marks on the reservoir. If the level
is below the MIN (B) mark, add the power steering
fluid to the appropriate level. Replace the cap
and completely tighten it.
What to Use
To determine what kind of fluid to use, see
Part D: Recommended Fluids and Lubricants on
page 382. Always use the proper fluid. Failure
to use the proper fluid can cause leaks and
damage hoses and seals.
279

(C) Aspect Ratio:A two-digit number that
indicates the tire height-to-width measurements.
For example, if the tire size aspect ratio is 70,
as shown in item C of the illustration, it would
mean that the tire’s sidewall is 70% 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 range and the speed rating
of a tire. The load range represents the load carry
capacity a tire is certified to carry. The speed
rating is the maximum speed a tire is certified to
carry a load. Speed ratings range from A to Z.Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the
tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples
of optional accessories are, automatic
transmission/transaxle, power steering, power
brakes, power windows, power seats, and
air conditioning.
Aspect Ratio:The relationship of a tire’s height
to its width.
Belt:A rubber coated layer of cords that is located
between the plies and the tread. Cords may be
made from steel or other reinforcing materials.
Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.

If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. If air goes out of a tire, it is
much more likely to leak out slowly. But if you
should ever have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will create a drag
that pulls the vehicle toward that side. Take your
foot off the accelerator pedal and grip the
steering wheel firmly. Steer to maintain lane
position, and then gently brake to a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction
you would use in a skid. In any rear blowout
remove your foot from the accelerator pedal. Get
the vehicle under control by steering the way
you want the vehicle to go. It may be very bumpy
and noisy, but you can still steer. Gently brake
to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
at tire. If it is used for anything else, you
or others could be badly injured or killed
if the vehicle slips off the jack. Use the
jack provided with your vehicle only for
changing a at tire.
If a tire goes flat, the next part shows how to use the
jacking equipment to change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel
damage by driving slowly to a level place.
Turn on your hazard warning flashers.

Automatic Transaxle Shift Lock Control
System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough
room around the vehicle. It should be parked
on a level surface.
2. Firmly apply the parking brake. SeeParking
Brake on page 116if necessary.
Be ready to apply the regular brake
immediately if the vehicle begins to move.
3. With the engine off, turn the ignition to ON,
but do not start the engine. Without applying
the regular brake, try to move the shift
lever out of PARK (P) with normal effort. If the
shift lever moves out of PARK (P), your
vehicle needs service.
Ignition Transaxle Lock Check
While parked, and with the parking brake set, try
to turn the ignition to LOCK in each shift lever
position.
•With an automatic transaxle, the ignition
should turn to LOCK only when the shift lever
is in PARK (P).
•With a manual transaxle, the ignition should
turn to LOCK only when you press the key
release button.
On all vehicles, the ignition key should come out
only in LOCK.
Turn the steering wheel to the left and to the right.
It should only lock when turned to the right.
378

Part C: Periodic Maintenance
Inspections
Listed in this part are inspections and services
which should be performed at least twice a
year (for instance, each spring and fall).You
should let your dealer’s service department
do these jobs. Make sure any necessary repairs
are completed at once.
Proper procedures to perform these services may
be found in a service manual. SeeService
Publications Ordering Information on page 406.
Steering, Suspension and Front
Drive Axle Boot and Seal Inspection
Inspect the front and rear suspension and
steering system for damaged, loose or missing
parts, signs of wear or lack of lubrication. Inspect
the power steering lines and hoses for proper
hook-up, binding, leaks, cracks, chafing, etc.
Clean and then inspect the drive axle boot seals
for damage, tears or leakage. Replace seals
if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the
body near the exhaust system. Look for broken,
damaged, missing or out-of-position parts as
well as open seams, holes, loose connections or
other conditions which could cause a heat
build-up in the floor pan or could let exhaust fumes
into the vehicle. SeeEngine Exhaust on
page 121.
Fuel System Inspection
Inspect the complete fuel system for damage
or leaks.
