Maintenance and care
Engine oil
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
nChecking the engine oil
Park the vehicle on level ground. After turning off the engine, wait
more than five minutes for the oil to drain back into the bottom of
the engine.
Hold a rag under the end and pull
the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.

nRecommended viscosity
SAE 5W-30 is the best choice for
good fuel economy, and good
starting in cold weather.
*: If SAE 5W-30 oil is not avail-
able, SAE 10W-30 oil may be
used. However, it should be
replaced with SAE 5W-30 at
the next oil change.
nHow to read oil container labels
Some oil containers are labeled with ILSAC certification marks that
help you to select the proper oil.

Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity
lThe 5W portion of the oil viscosity rating indicates the characteristic of
the oil which allows cold startability. Oils with a lower value before the W
allow for easier starting of the engine in cold weather.
lThe 30 in 5W-30 indicates the oil viscosity when the oil is at its operating
temperature. An oil with a higher viscosity may be better suited if the
vehicle is operated at high speeds, or under extreme load condition.

6-1. Specifications
nTemperature A, B, C
The temperature grades are A (the highest), B, and C, representing
the tire's resistance to the generation of heat and its ability to dissipate
heat when tested under controlled conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire fail-
ure.
The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of performance on the laboratory
test wheel than the minimum required by law.
Warning: The temperature grades for this tire are established for a tire that
is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
