22 In Brief
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits0163. The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See Tire Pressure Monitor System
0 252.Fuel (2.0L Turbo Engine)
Premium Recommended Fuel
Use premium 93 octane unleaded
gasoline in your vehicle. Unleaded
gasoline with an octane rating as
low as 87 may be used, but it will
reduce performance and fuel
economy. See Fuel0205.
Fuel (2.4L Engine)
Regular Fuel
Use only unleaded gasoline rated
87 octane or higher in your vehicle.
Do not use gasoline with an octane rating lower as it may result in
vehicle damage and lower fuel
economy. See
Fuel0205.
E85 or FlexFuel
No E85 or FlexFuel
Gasoline-ethanol fuel blends greater
than E15 (15% ethanol by volume),
such as E85, cannot be used in this
vehicle.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE
OIL SOON message when it is time
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.

Instantaneous Fuel Economy :
Displays the current fuel economy in
either liters per 100 kilometers(L/100 km) or miles per
gallon (mpg). This number reflects
only the approximate fuel economy
that the vehicle has right now and
changes frequently as driving
conditions change.
Average Speed : Displays the
average speed of the vehicle in
kilometers per hour (km/h) or miles
per hour (mph). This average is
calculated based on the various
vehicle speeds recorded since the
last reset of this value. The average
speed can be reset by pressing and
holding
Vwhile this display is
active.
Timer : To start the timer, press
V
while this display is active. The
display will show the amount of time
that has passed since the timer was
last reset. To stop the timer, press
V
briefly while this display is active
and the timer is running. To reset
the timer to zero, press and hold
V
while this display is active. 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 0128.
The oil should be changed as soon
as possible. See Engine Oil0218.
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended in the Maintenance
Schedule. See Maintenance
Schedule 0294.
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
Vfor several
seconds while the Oil Life display is
active. See Engine Oil Life System
0 220. Coolant Temperature :
Displays
the coolant temperature in either
degrees Celsius (°C) or degrees
Fahrenheit (°F).

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.

economy (AFE) that is achieved for
a selected distance. The left hand
side displays a running average of
fuel economy for the most recently
traveled selected distance. The
center bar graph displays the
instantaneous fuel economy. Press
the

been traveled. The display provides
feedback on how current driving
behavior in the bar graph affects the
running average in the left display
and how well recent driving
compares to the best that has been
achieved.
Fuel Used and 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 the
T
button while the Fuel Used display

Economy Trend : Displays history
of the Average Fuel Economy from
the last 50 km (30 miles). Each bar
represents about 5 km (3 miles) of
driving. The fuel economy will range
from 0 –15 L/100 km (0 –50 mpg).
During driving the bars will shift to
always reflect the most recent
distance on the right side. This
display cannot be reset.
Eco Index : The bar graph on the
left hand side provides feedback on
the efficiency of current driving

(3) 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 3 of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(4) 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.
(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
0 251.
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.

Vehicle Care 251
Tire Pressure
Tires need the correct amount of
air pressure to operate
effectively.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.
(Continued)
Caution (Continued)
.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. See
Vehicle Load Limits 0163.
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. Do not forget the compact
spare, if the vehicle has one.
The cold compact spare tire
pressure should be at 420 kPa
(60 psi). See
Compact Spare
Tire 0277.
How to Check
Use a good quality pocket-type
gauge to check 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 a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
