Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment: .
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0245.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
SeeEngine Compartment Overview
0 242 for the location of the engine
oil dipstick.

Service and Maintenance 319
Engine Oil Change
Every 24 months or when the
CHANGE ENGINE OIL SOON
message displays, change the
engine oil and filter as soon as
possible, within the next 1 000 km/
600 mi. The engine oil and filter
must be changed at least once
every 24 months. After each oil and
filter change, the oil life system must
be reset. SeeEngine Oil Life
System 0245. More frequent
changes may be required when the
vehicle is exposed to a corrosive
environment, such as areas of high
humidity, along an ocean coast,
and/or areas that apply road salt
during winter.
Your trained dealer technician can
perform this work. If the engine oil
life system is reset accidentally,
service the vehicle within 5 000 km/
3,000 mi since the last service.
Reset the oil life system when the
oil is changed.
Tire Rotation and Required
Services Every 12 000 km/
7,500 mi
Rotate the tires, if recommended for
the vehicle, and perform the
following services. See Tire
Rotation 0284.
. Check engine oil level and oil
life percentage. If needed,
change engine oil and filter, and
reset oil life system. See Engine
Oil 0243 andEngine Oil Life
System 0245.
. Check engine coolant level. See
Engine Coolant 0250.
. Check windshield washer fluid
level. See Washer Fluid 0253.
. Visually inspect windshield wiper
blades for wear, cracking,
or contamination. See Exterior
Care 0308. Replace worn or
damaged wiper blades. See
Wiper Blade
Replacement 0259. .
Check tire inflation pressures.
See Tire Pressure 0278.
. Inspect tire wear. See Tire
Inspection 0283.
. Visually check for fluid leaks.
. Inspect engine air cleaner filter.
See Engine Air Cleaner/
Filter 0246.
. Inspect brake system. See
Exterior Care 0308.
. Visually inspect steering,
suspension, and chassis
components for damaged, loose,
or missing parts or signs of
wear. See Exterior Care 0308.
. Check restraint system
components. See Safety System
Check 063.
. Visually inspect fuel system for
damage or leaks.
. Visually inspect exhaust system
and nearby heat shields for
loose or damaged parts.
