Maintenance Schedule
Introduction
Notice:Maintenance intervals, checks, inspections,
recommended fluids, and lubricants are necessary
to keep this vehicle in good working condition.
Damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
As the vehicle owner, you are responsible for the
scheduled maintenance in this section. We recommend
having your dealer perform these services. Proper
vehicle maintenance helps to keep the vehicle in good
working condition, improves fuel economy, and reduces
vehicle emissions for better air quality.
Because of all the different ways people use vehicles,
maintenance needs vary. The vehicle might need more
frequent checks and services. Please read the
information under Scheduled Maintenance. To keep the
vehicle in good condition, see your dealer.
The maintenance schedule is for vehicles that:
.carry passengers and cargo within recommended
limits on the Tire and Loading Information label.
See Loading the Vehicle on page 5‑22.
.are driven on reasonable road surfaces within legal
driving limits.
.use the recommended fuel. See Gasoline Octaneon page 6‑6.
{WARNING:
Performing maintenance work on a vehicle can be
dangerous. In trying to do some jobs, you can be
seriously injured. Do your own maintenance work
only if you have the required know-how and the
proper tools and equipment for the job. If you
have any doubt, see your dealer to have a
qualified technician do the work. See Doing Your
Own Service Work on page 6‑4.
At your dealer, you can be certain that you will receive
the highest level of service available. Your dealer has
specially trained service technicians, uses genuine
replacement parts, as well as, up‐to‐date tools and
equipment to ensure fast and accurate diagnostics.
The proper replacement parts, fluids, and lubricants to
use are listed in Recommended Fluids and Lubricants
on page 7‑8andMaintenance Replacement Partson
page 7‑10. We recommend the use of genuine parts
from your dealer.

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. Tires should be rotated every
12 000 km/7,500 miles. SeeTire Inspection and
Rotation on page 6‑60.
Scheduled Maintenance
When the Change Oil Soon Message
Displays
Change engine oil and filter. See Engine Oilon
page 6‑16. 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 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 6‑19.
When the Change Oil Soon message displays, certain
services, checks, and inspections are required.
Every Engine Oil Change
.Change engine oil and filter. Reset oil life system.
See Engine Oilon page 6‑16andEngine Oil Life
Systemon page 6‑19. An Emission Control
Service.
.Engine coolant level check. See Engine Coolanton page 6‑24.
.Engine cooling system inspection. Visual
inspection of hoses, pipes, fittings, and clamps and
replacement, if needed.
.Windshield washer fluid level check. See
Windshield Washer Fluid on page 6‑30.
.Windshield wiper blade inspection for wear,
cracking, or contamination and windshield and
wiper blade cleaning, if contaminated. See
Windshield and Wiper Blades
on page 6‑96. Worn
or damaged wiper blade replacement. See
Windshield Wiper Blade Replacement
on
page 6‑46.
.Tire inflation pressures check. See Inflation - Tire
Pressure on page 6‑54.
.Tire wear inspection. See Tire Inspection and
Rotation on page 6‑60.
.Rotate tires if necessary. See Tire Inspection and
Rotation on page 6‑60.

whichever occurs first).
.Steering and suspension inspection. Visual
inspection for damaged, loose, or missing parts or
signs of wear.
.Body hinges and latches, key lock cylinders, and
rear compartment hinges lubrication. See
Recommended Fluids and Lubricants
on
page 7‑8. More frequent lubrication may be
required when the 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 2‑73.
.Fuel system inspection for damage or leaks.
.Exhaust system and nearby heat shields
inspection for loose or damaged components.

routing, and condition. Check that the purge valve,
if the vehicle has one, works properly. Replace as
needed.An Emission Control Service. The U.S.
Environmental Protection Agency or the California
Air Resources Board has determined that the
failure to perform this maintenance item will not
nullify the emission warranty or limit recall liability
prior to the completion of the vehicle's useful life.
We, however, urge that all recommended
maintenance services be performed at the
indicated intervals and the maintenance be
recorded.

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 3‑30.
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.

{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 3‑30.
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 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.

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.
