Tire Size
The following illustration
shows 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 rst character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire
and Rim Association. Tires
engineered to European
standards do not use the
letter P as the rst character
in the tire size.(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
range and speed rating of the
tire. The load index represents
the load carry capacity a tire is
certi ed to carry. The load index
can range from 1 to 279. The
speed rating is the maximum
speed a tire is certi ed to carry
a load. Speed ratings range
fromAtoZ.
Tire Terminology and
De nitions
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, power
steering, power brakes, power
windows, power seats, and air
conditioning.

Tire Changing
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 at tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip thesteering wheel rmly. 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. If a
jack is provided with the vehicle, it
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. If a jack is provided
with the vehicle, only use it for
changing a at tire.
If a tire goes at, the next part
shows how to use the jacking
equipment to change a at tire
safely.

When dinghy towing, be sure to
follow the posted legal speed limit.
1. Put the shift lever in Neutral.
2. Turn the ignition to
ACC/ACCESSORY to avoid
locking the steering wheel.
Make sure the audio system
is turned off and that nothing is
plugged into the power outlets.
3. Release the parking brake.
After dinghy towing, let the engine
idle for more than three minutes
before driving the vehicle.Do not tow your vehicle from
the rear. Your vehicle could be badly
damaged and the repairs would
not be covered by your warranty.
Dolly Towing
(All-Wheel-Drive Vehicles)
All-wheel-drive vehicles must not
be towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed
on a platform trailer with all four
wheels off of the ground.
Dolly Towing
(Front-Wheel-Drive
Vehicles Only)
To tow your front-wheel-drive
vehicle using a dolly, follow
these steps:
1. Put the front wheels on a dolly.
2. Move the shift lever to P (Park)
for an automatic transmission
or Neutral for a manual
transmission.
3. Set the parking brake.

4. Clamp the steering wheel in a
straight-ahead position with a
clamping device designed
for towing.
5. Remove the key from the
ignition.
6. Secure the vehicle to the dolly.
7. Release the parking brake.
Towing a Trailer
{CAUTION
The driver can lose control when
pulling a trailer if the correct
equipment is not used or the
vehicle is not driven properly.
For example, if the trailer is too
heavy, the brakes may not work
well or even at all. The driver and
passengers could be seriously
(Continued)
CAUTION (Continued)
injured. The vehicle may also be
damaged; the resulting repairs
would not be covered by the
vehicle warranty. Pull a trailer only
if all the steps in this section have
been followed. Ask your
dealer/retailer for advice and
information about towing a trailer
with the vehicle.
Your vehicle can tow a trailer if it
is equipped with the proper trailer
towing equipment. To identify the
vehicle trailering capacity of your
vehicle, you should read the
information in “Weight of the Trailer”
that appears later in this section.
Trailering is different than just driving
your vehicle by itself. Trailering
means changes in handling,acceleration, braking, durability and
fuel economy. Successful, safe
trailering takes correct equipment,
and it has to be used properly.
That is the reason for this part.
In it are many time-tested, important
trailering tips and safety rules. Many
of these are important for your safety
and that of your passengers.
So please read this section
carefully before you pull a trailer.
Load-pulling components such as
the engine, transmission, wheel
assemblies and tires are forced to
work harder against the drag of
the added weight. The engine
is required to operate at relatively
higher speeds and under greater
loads, generating extra heat.
In addition, the trailer adds
considerably to wind resistance,
increasing the pulling requirements.

Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving your vehicle without a trailer.
This can help you avoid situations
that require heavy braking and
sudden turns.
Passing
More distance in front is needed to
pass when towing a trailer. And,
because the tow vehicle and trailer
are longer, you will need to go
farther beyond the passed vehicle
before you can return to your lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, just move that
hand to the left. To move the trailer
to the right, move your hand to the
right. Always back up slowly and, if
possible, have someone guide you.
Making Turns
Notice:Making very sharp turns
while trailering could cause
the trailer to come in contact with
the vehicle. The vehicle could
be damaged. Avoid making very
sharp turns while trailering.
When you are turning with a trailer,
make wider turns than normal.
Do this so your trailer will not strike
soft shoulders, curbs, road signs,
trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a
Trailer
When you tow a trailer, your vehicle
may need a different turn signal
asher and/or extra wiring. Check
with your dealer/retailer. The arrows
on the instrument panel ash
whenever you signal a turn or lane
change. Properly hooked up, the
trailer lamps also ash, telling other
drivers you are about to turn, change
lanes or stop.When towing a trailer, the arrows
on the instrument panel will ash for
turns even if the bulbs on the trailer
are burned out. Thus, you may think
drivers behind you are seeing your
signal when they are not. It is
important to check occasionally to be
sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower
gearbeforeyou start down a long or
steep downgrade. If you do not shift
down, you might have to use your
brakes so much that they would get
hot and no longer work well.
On a long uphill grade, shift down
and reduce your speed to around
45 mph (70 km/h) to reduce the
possibility of the engine and the
transmission overheating.
