Oil Life:Displays 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 5-37. The oil should be
changed as soon as possible. See
Engine Oil on page 10-12. In
addition to the engine oil life system
monitoring the oil life, additional
maintenance is recommended in the
Maintenance Schedule. See
Maintenance Schedule on
page 11-2.
The Oil Life display must be reset
after each oil change. It will not
reset itself. Do not reset the Oil Life
display accidentally at any time
other than when the oil has just
been changed. It cannot be reset
accurately until the next oil change.
To reset the engine oil life system,
press and hold SEL for several seconds while the Oil Life display is
active. See
Engine Oil Life System
on page 10-18.
Tire Pressure: Displays the
approximate pressures of all four
tires. Tire pressure is displayed in
either kilopascal (kPa) or in pounds
per square inch (psi). If the pressure
is low, the value for that tire is
shown in amber. See Tire Pressure
Monitor System on page 10-57 and
Tire Pressure Monitor Operation on
page 10-58.
Best Average Fuel Economy:
Displays the average fuel economy,
the best fuel economy over the
selected distance, and a bar graph
showing instantaneous fuel
economy. Press
pto change the
selected distance.
Fuel Used/Timer: Displays the
approximate liters (L) or
gallons (gal) of fuel that have been
used since last reset. The fuel used
can be reset by pressing and
holding SEL while this display is
active. This display can also be used as a
timer. To start/stop the timer, press
pwhile this display is active and
then SEL to start/stop the timer. The
display will show the amount of time
that has passed since the timer was
last reset. To reset the timer to zero,
press and hold SEL or use
pto
access the menu while this display
is active.
ECO Index: Aids the driver in
determining how efficiently they are
driving.
This display may also show the
number of cylinders the vehicle is
running on. See Active Fuel
Management
®on page 9-25.
Speed Limit: Displays sign
information, which comes from a
roadway database in the onboard
navigation.
Engine Hours/Lifetime Revs:
Displays the total number of hours
the engine has run. It also shows
total engine revolutions divided by
10,000.

Manual Transmission
To operate:
1 (First): Press the clutch pedal
and shift into 1 (First). Then slowly
let up on the clutch pedal as the
accelerator pedal is pressed.
This can be done if the vehicle is
going less than 64 km/h (40 mph).
If the vehicle is at a complete stop
and it is hard to shift into 1 (First),
put the shift lever in Neutral and let
up on the clutch. Then press the
clutch pedal back down and shift
into 1 (First). 2 (Second):
Press the clutch pedal
while letting up on the accelerator
pedal and shift into 2 (Second).
Then, slowly let up on the clutch

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10-18.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil (Except
Z51 and Z06)
If the ENGINE OIL LOW–ADD OIL
message displays on the Driver
Information Center (DIC), check the
engine oil level right away. See
Engine Oil Messages on page 5-37.
Check the engine oil level regularly.
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
SeeEngine Compartment Overview
on page 10-7 for the location of the
engine oil dipstick.

Warning (Continued)
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
{Warning
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
{Caution
Using coolant other than
DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.
Cooling System (Aero
Panel)
The aero panel enhances
aerodynamic efficiency and
improves fuel economy.
Remove the aero panel and bracket
to improve engine cooling and air
conditioning performance when
driving aggressively or in hot
weather.

(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Service Description
:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
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 kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight
:The
combined weight of optional
accessories. Some examples of
optional accessories are automatic transmission, 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 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 kPa (kilopascal)
or psi (pounds per square inch) before a tire has built up heat
from driving. See
Tire Pressure
on page 10-55.
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.

10-56 Vehicle Care
{Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can
result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards. The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire
inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity.
For additional information
regarding how much weight the
vehicle can carry, and an
example of the Tire and Loading
Information label, see
Vehicle
Load Limits on page 9-14. How
the vehicle is loaded affects
vehicle handling and ride
comfort. Never load the vehicle
with more weight than it was
designed to carry.
When to Check
Check the tires once a month
or more. How to Check
Use a good quality pocket-type
gauge to check the tire
pressure. Proper tire inflation
cannot be determined by looking
at the tire. Check the tire
inflation pressure when the tires
are cold, meaning the vehicle
has not been driven for at least
three hours or no more than
1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get the pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
inflation pressure in high, press
on the metal stem in the center
