The required rotation method for directional tires is to
swap the front tire with the rear on the same side of the
vehicle. Do not cross switch tires without dismounting
the tires and re-mounting them in the correct rotational
direction.
SELECTING FUEL
2.4L TURBO
Your engine is designed to meet all emis-
sion regulations and provide excellent fuel
economy and performance when using
high quality unleaded gasoline having an
octane rating of 91. The purchase of higher
octane is not recommended.
High quality unleaded gasoline having a minumum
octane rating of 87 may safely be used for your vehicle.
Use of these lower octane gasolines, however, may result
in reduced acceleration performance.
If low octane fuel (below the recommended 91 octane
(R+M)/2)) is used, boost will be reduced significantly.
Normal boost levels will return once the recommended
fuel is used and the engine controller adapts to the fuel
octane level.
Spark Knock
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. Engine damage resulting from operation with a
heavy spark knock may not be covered by the new
vehicle warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of “regular” gasoline be-
fore considering service for the vehicle.
Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) to define
fuel properties necessary to deliver enhanced emissions,
engine performance, and durability for your vehicle. The
manufacturer recommends the use of gasolines that meet
the WWFC specifications if they are available.
