WARNING!(Continued)
•Check mounting of mats on a regular basis. Always
properly reinstall and secure floor mats that have
been removed for cleaning.
•Always make sure that objects cannot fall into the
driver footwell while the vehicle is moving. Ob-
jects can become trapped under the brake pedal
and accelerator pedal causing a loss of vehicle
control.
•If required, mounting posts must be properly in-
stalled, if not equipped from the factory.
Failure to properly follow floor mat installation or
mounting can cause interference with the brake
pedal and accelerator pedal operation causing loss of
control of the vehicle.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.

The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
13. Fuel Gauge/Fuel Door Reminder
The fuel pump symbol points to the side of the vehicle
where the fuel door is located. The pointer shows the
level of fuel in the fuel tank when the ignition switch is in
the ON/RUN position.
14. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.

STARTING AND OPERATING 417

WARNING!
Significant over or under-inflation of tires, or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.
The Anti-Lock Brake System conducts a low speed self-
test at about 12 mph (20 km/h). If for any reason your
foot is on the brake when the vehicle reaches 12 mph
(20 km/h), this check will be delayed until 25 mph
(40 km/h).
The Anti-Lock Brake System pump motor runs during
the self-test, and during an ABS stop, to provide the
regulated hydraulic pressure. The motor pump makes a
low humming noise during operation; this is normal.
WARNING!
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
•The Anti-Lock Brake System (ABS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can they increase braking or steering
efficiency beyond that afforded by the condition of
the vehicle brakes and tires or the traction afforded.
•The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
•The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or
the safety of others.
474 STARTING AND OPERATING

EXAMPLE:
H= Speed Symbol
– A symbol indicating the range of speeds at which a tire can carry a load corresponding to
its load index under certain operating conditions
– The maximum speed corresponding to the speed symbol should only be achieved under
specified operating conditions (i.e., tire pressure, vehicle loading, road conditions, and
posted speed limits)
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL)
tire:
•XL= Extra load (or reinforced) tire, or
•LL= Light load tire or
•C, D, E, F, G= Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load– Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure– Maximum pressure indicates the maximum permissible cold tire inflation pressure for this
tire
496 STARTING AND OPERATING

EXAMPLE:
DOT MA L9 ABCD 0301
01= Number representing the year in which the tire was manufactured (two digits)
– 01 means the year 2001
– Prior to July 2000, tire manufacturers were only required to have one number to represent the year
in which the tire was manufactured. Example: 031 could represent the 3rd week of 1981 or 1991
Tire Terminology And Definitions
TermDefinition
B-PillarThe vehicle B-Pillar is the structural member of the body located
behind the front door.
Cold Tire Inflation PressureCold tire inflation pressure is defined as the tire pressure after
the vehicle has not been driven for at least three hours, or driven
less than 1 mile (1.6 km) after sitting for a minimum of three
hours. Inflation pressure is measured in units of PSI (pounds per
square inch) or kPa (kilopascals).
498 STARTING AND OPERATING

TermDefinition
Maximum Inflation PressureThe maximum inflation pressure is the maximum permissible
cold tire inflation pressure for this tire. The maximum inflation
pressure is molded into the sidewall.
Recommended Cold Tire Inflation Pres-
sure
Vehicle manufacturer’s recommended cold tire inflation pressure
as shown on the tire placard.
Tire PlacardA label permanently attached to the vehicle describing the vehi-
