Safety
WARNING!
Improperly inflated tires are danger-
ous and can cause collisions.
Under-inflation increases tire flexing and can
result over-heating and in tire failure.
Over-inflation reduces a tire's ability to cush-
ion shock. Objects on the road and chuckholes
can cause damage that result in tire failure.
Over-inflated or under-inflated tires can affect
vehicle handling and can fail suddenly, resulting
in loss of vehicle control.
Unequal tire pressures can cause steering
problems.You could lose control of your vehicle.
Unequal tire pressures from one side of the
vehicle to the other can cause the vehicle to drift
to the right or left .
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnor-
mal wear patterns will reduce tread life resulting in a
need for earlier tire replacement. Under-inflation, also
increases tire rolling resistance resulting in higher fuelconsumption. Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride.
TIRE INFLATION PRESSURES
The proper cold tire inflation pressure is listed on the
driver's side B-Pillar or rear edge of the driver's side
door.
The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at
least once a month. Use a good quality pocket-type
gauge to check tire pressure. Do not make a visual
judgement when determining proper inflation. Radial
tires may look properly inflated even when they are
under-inflated.
After inspecting or adjusting the tire
pressure, always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which could damage
the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure.” Cold tire inflation pres-
sure is defined as the tire pressure after the vehicle has
not been driven for at least three hours, or driven less
than 1.6 km after a three hour period. The cold tire
inflation pressure must not exceed the maximum infla-
tion pressure molded into the tire sidewall.

FUEL REQUIREMENTS — GASOLINE ENGINE
All engines are designed to meet all emissions regula-
tions and provide excellent fuel economy and perfor-
mance when using high quality unleaded gasoline with a
minimum research octane rating of 91. The use of
premium gasoline is not recommended, as it will not
provide any benefit over regular gasoline in these en-gines.
Light spark knock at low engine speeds is not harmful
to your engine. However, continued heavy spark knock
at high speeds can cause damage and immediate service
is required. Poor quality gasoline can cause problems
such as hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand of
gasoline before considering service for the vehicle.
Over 40 auto manufacturer's world wide have issued
and endorsed consistent gasoline specifications (the
Worldwide Fuel Charter, WWFC) which define fuel
properties necessary to deliver enhanced emissions,
performance, and durability for your vehicle. The
manufacturer recommends the use of gasoline that
meets the WWFC specifications if they are available. Methanol
(Methyl or Wood Alcohol) is used in a variety of
concentrations when blended with unleaded gasoline.
You may find fuels containing 3% or more methanol
along with other alcohols called cosolvents. Problemsthat result from using methanol/gasoline or E-85 Etha-
nol blends are not the responsibility of the manufac-
turer. While MTBE is an oxygenate made from Metha-
nol, it does not have the negative effects of Methanol.
Do not use gasolines containing Metha-
nol or E-85 Ethanol. Use of these blends
may result in starting and driveability
problems and may damage critical fuel system
components.
Ethanol
The manufacturer recommends that your vehicle be
operated on fuel containing no more than 10% ethanol.
Purchasing your fuel from a reputable supplier may
reduce the risk of exceeding this 10% limit and/or of
receiving fuel with abnormal properties. It should also
be noted that an increase in fuel consumption should
be expected when using ethanol-blended fuels, due to
the lower energy content of ethanol. Problems that
result from using methanol/gasoline or E-85 ethanol
blends are not the responsibility of the manufacturer.
While MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
