Alignment And Balance; Fuel Requirements - Chrysler 2004 Concorde Owner's Manual

Alignment And Balance

The suspension components of your vehicle should be
inspected and aligned when needed to obtain full tire
tread mileage.
Poor suspension alignment may result in:
• fast tire wear;
• uneven tire wear, such as feathering and one-sided
wear;
• vehicle pull to right or left.
Tires may also cause vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.
Improper alignment will not cause vehicle vibration.
Vehicle vibration may be a result of tire and wheel
out-of-balance. Proper balancing will reduce vibration
and avoid tire cupping and spotty wear.

FUEL REQUIREMENTS

Your engine is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and performance when us-
ing high quality unleaded gasoline having
an octane range of 87 to 89 or higher. The
manufacturer recommends the use of 89
octane for optimum performance.
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 should be reported to
your dealer immediately. Engine damage resulting from
operating 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 stumble. If you experience these
problems, try another brand of gasoline before consider-
ing service for the vehicle.
