Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule in this manual for
changing engine oil.
The oil pressure light should come
on briefly as the engine is started.
If it does not come on have the
vehicle serviced by your dealer/
retailer.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem. See
your dealer/retailer.
Fuel Economy Light
For vehicles with the fuel economy
mode light, it comes on when the
eco (economy) switch, located on
the center console near the shifter,
is pressed. For vehicles with a
Driver Information Center (DIC) an
ECO Mode On message displays.
See Fuel System Messages
on
page 4‑32for more information.
Press the switch again to turn
off the light and exit the fuel
saver mode.

The display will show a vehicle with
the approximate pressures of all
four tires. Tire pressure is displayed
in either pounds per square
inch (psi) or in kilopascal (kPa).
Any time the tire pressures are
adjusted the system needs to
relearn the new pressures. To
relearn the tire pressures press
Vor

display is active. The display will
ask for confirmation of a relearn.
Press

more information. Remaining Oil Life
This display shows an estimate of
the oil's remaining useful life.
If
“Remaining Oil Life 99%” is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low,
the “Change Engine Oil Soon”
message will appear on the display.
See Engine Oil Messages
on
page 4‑31. The oil should be
changed as soon as possible. See
Engine Oil
on page 9‑10. In
addition to the engine oil life system
monitoring the oil life, additional
maintenance is recommended in the
Maintenance Schedule in this
manual. See Scheduled

of the low oil pressure has been
corrected. Check the oil as soon as
possible and have your vehicle
serviced by your dealer/retailer.
Engine Power Messages

9-18 Vehicle Care
How to Add Coolant to the
Coolant Surge Tank
Notice:This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
If you have not found a problem
yet, check to see if coolant is visible
in the coolant surge tank. If coolant
is visible but the coolant level is
not at the COLD FILL line, add a
50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant at
the coolant surge tank, but be sure
the cooling system, including the
coolant surge tank pressure cap, is
cool before you do it. See Engine
Overheating
on page 9‑20for more
information.
{WARNING
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn
the coolant surge tank pressure
cap —even a little —they can
come out at high speed. Never
turn the cap when the cooling
system, including the coolant
surge tank pressure cap, is hot.
Wait for the cooling system and
coolant surge tank pressure cap
to cool if you ever have to turn
the pressure cap.
{WARNING
Adding only plain water to
the cooling system can be
dangerous. Plain water, or some
other liquid such as alcohol, can
boil before the proper coolant
(Continued)
WARNING (Continued)
mixture will. The vehicle's coolant
warning system is set for the
proper coolant mixture. With plain
water or the wrong mixture, the
engine could get too hot but you
would not get the overheat
warning. The engine could catch
fire and you or others could be
burned. Use a 50/50 mixture of
clean, drinkable water and
DEX-COOL
®coolant.
{WARNING
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.

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 psi (pounds per
square inch) or kPa (kilopascal).
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.
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 psi (pounds per
square inch) or kPa (kilopascal)
before a tire has built up heat
from driving. See Tire Pressure
on page 9‑52. Curb Weight
: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.
DOT Markings
:A code molded
into the sidewall of a tire
signifying that the tire is in
compliance with the U.S.
Department of Transportation
(DOT) motor vehicle safety
standards. The DOT code
includes the Tire Identification
Number (TIN), an alphanumeric
designator which can also
identify the tire manufacturer,
production plant, brand, and
date of production.
