Tire Pressure Light
This light will come on
briey when you turn
the ignition on.
This light will also come on when one or more of
your tires are signicantly underinated.
A LOW TIRE PRESS DIC message will
accompany the light, seeOther Messages on
page 219for more information.Stop and check your tires as soon as it is safe to do
so. If underinated, inate to the proper pressure.
SeeTires on page 413for more information.
This light will ash for about 60 seconds and then
turn on solid if a problem is detected with the
Tire Pressure Monitor system.
SeeTire Pressure Monitor System on page 423
for more information.

LEFT DOOR AJAR
This message displays anytime the engine is
running, the transmission is not in PARK (P), and
the driver’s door is open or ajar. A chime
sounds when the vehicle’s speed is greater than
3 mph (5 km/h).
LOW BRAKE FLUID
This message displays if the engine is running to
inform the driver that the brake uid level is
low. Have the brake system serviced by your
dealer as soon as possible. See “Brake Fluid”
underBrakes on page 399.
LOW COOLANT
This message displays when there is a low level
of engine coolant. Have the cooling system
serviced by your dealer as soon as possible. See
Engine Coolant on page 385.
LOW FUEL
This message displays when the fuel supply is
less than 5 gallons (18.9 L) and the display
is turned off. A single chime also sounds when
this message is displayed.
LOW OIL LEVEL
For correct operation of the low oil sensing
system, your vehicle should be on a level surface.
A false LOW OIL LEVEL message may display
if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil
level if the engine has been off for a short
period of time, and the oil level is never checked
while the engine is running. If the LOW OIL
LEVEL message displays, and your vehicle has
been parked on level ground with the engine off for
at least 30 minutes, the oil level should be
checked by observing the oil dipstick. Prior to
checking the oil level, make sure the engine has
been off for a few minutes and your vehicle is on a
level surface. Then check the dipstick and add
oil if necessary. SeeEngine Oil on page 377.
LOW OIL PRESSURE
If this message displays while the engine is
running, stop the engine and do not operate the
vehicle until the cause of low oil pressure is
corrected. Severe damage to the engine can
result. A multiple chime sounds when this
message is displayed.

If the LOW OIL LEVEL or LOW OIL PRESSURE
message on the Driver Information Center
(DIC) appears, it means you need to check the
engine oil level right away. For more information,
see LOW OIL LEVEL and LOW OIL PRESSURE
underDIC Warnings and Messages on page 206.
You should check the engine oil level regularly;
this is an added reminder.
Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 374
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.

(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 certied to carry. The load index
can range from 1 to 279. The speed rating is
the maximum speed a tire is certied 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.
Bias Ply Tire:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.
Cold Tire Pressure:The amount of air pressure
in a tire, measured in pounds per square inch
(psi) or kilopascals (kPa) before a tire has built up
heat from driving. SeeInation - Tire Pressure
on page 422.
Curb Weight:This means the weight of a motor
vehicle with standard and optional equipment
including the maximum capacity of fuel, oil, and
coolant, but without passengers and cargo.
417

Ination - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under-ination or over-ination is all right. It is
not. If your tires do not have enough air
(under-ination), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazardsA Tire and Loading Information label is attached to
the center pillar, below the driver’s door latch. This
label shows your vehicle’s original equipment tires
and the correct ination pressures for your tires
when they are cold. The recommended cold tire
ination pressure, shown on the label, is the
minimum amount of air pressure needed to support
your vehicle’s maximum load carrying capacity.
For additional information regarding how much
weight your vehicle can carry, and an example of
the tire and loading information label, see
Loading Your Vehicle on page 354. How you load
your vehicle affects vehicle handling and ride
comfort, never load your vehicle with more weight
than it was designed to carry.
When to Check
Check your tires once a month or more.
