Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). SeeTire Inspection
and Rotation on page 6-62 .
Scheduled Maintenance
When the Change Oil Soon Message
Displays
Change engine oil and filter. See Engine Oil on
page 6-13. An Emission Control Service.
When the Change Oil Soon message displays, service
is required for the vehicle as soon as possible, within
the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset.
Your dealer/retailer has trained service technicians who
will perform this work and reset the system. If the
engine oil life system is reset accidentally, service the
vehicle within 5 000 km/3,000 miles since the last
service. Reset the oil life system whenever the oil is
changed. See Engine Oil Life System on page 6-16 .When the Change Oil Soon message displays, certain
services, checks, and inspections are required. The
services described for Maintenance
Ishould be
performed at every engine oil change. The services
described for Maintenance IIshould be performed when:
•Maintenance Iwas performed the last time the
engine oil was changed.
•It has been 10 months or more since the Change
Oil Soon message has displayed or since the last
service.

•Body hinges and latches, key lock cylinders, and
trunk lid hinges and latches lubrication. See
Recommended Fluids and Lubricants on page 7-10 .
More frequent lubrication may be required when
vehicle is exposed to a corrosive environment.
Applying silicone grease on weatherstrips with a
clean cloth makes them last longer, seal better, and
not stick or squeak.
•Restraint system component check. See Checking
the Restraint Systems on page 2-71 .
•Automatic transmission fluid level check and adding
fluid, if needed. SeeAutomatic Transmission Fluid
on page 6-19.

Owner Checks and Services
Starter Switch Check
{WARNING:
When you are doing this inspection, the vehicle
could move suddenly. If the vehicle moves, you or
others could be injured.
1. Before starting this check, be sure there is enough room around the vehicle.
2. Firmly apply both the parking brake and the regular brake. See Parking Brake on page 3-29 .
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. For automatic transmission vehicles, try to start the engine in each gear. The starter should work only
in P (Park) or N (Neutral). If the starter works in any
other position, your vehicle needs service.
For manual transmission vehicles, put the shift lever
in Neutral, push the clutch pedal down halfway, and
try to start the engine. The starter should work only
when the clutch pedal is pushed down all the way to
the floor. If the starter works when the clutch pedal is
not pushed all the way down, your vehicle needs
service.
Automatic Transmission Shift Lock
Control System Check
{WARNING:
When you are doing this inspection, the vehicle
could move suddenly. If the vehicle moves, you or
others could be injured.
1. Before starting this check, be sure there is enough room around the vehicle. It should be parked on a
level surface.
2. Firmly apply the parking brake. See Parking Brake
on page 3-29.
Be ready to apply the regular brake immediately if
the vehicle begins to move.
3. With the engine off, turn the ignition to ON/RUN, but do not start the engine. Without applying the
regular brake, try to move the shift lever out
of P (Park) with normal effort. If the shift lever
moves out of P (Park), contact your dealer/retailer
for service.

Ignition Transmission Lock Check
While parked, and with the parking brake set, try to turn
the ignition to LOCK/OFF in each shift lever position.
•For automatic transmission vehicles, the ignition
should turn to LOCK/OFF only when the shift
lever is in P (Park). The ignition key should come
out only in LOCK/OFF.
•For manual transmission vehicles, the ignition key
should come out only in LOCK/OFF.
Turn the steering wheel to the left and to the right. It
should only lock when turned to the right.
Contact your dealer/retailer if service is required.
Parking Brake and Automatic
Transmission P (Park) Mechanism
Check
{WARNING:
When you are doing this check, the vehicle could
begin to move. You or others could be injured and
property could be damaged. Make sure there is
room in front of the vehicle in case it begins to roll.
Be ready to apply the regular brake at once should
the vehicle begin to move.
Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake, set the
parking brake.
•To check the parking brake’s holding ability: With the
engine running and the transmission in N (Neutral),
slowly remove foot pressure from the regular brake
pedal. Do this until the vehicle is held by the parking
brake only.
•To check the P (Park) mechanism’s holding ability:
With the engine running, shift to P (Park). Then
release the parking brake followed by the regular
brake.
Contact your dealer/retailer if service is required.
