Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 4‑26for more information.
Notice: If an airbag covering is damaged, opened,
or broken, the airbag may not work properly. Do not
open or break the airbag coverings. If there are any
opened or broken airbag covers, have the airbag
covering and/or airbag module replaced. For the
location of the airbag modules, see What Makes an
Airbag Inflate?
on page 2‑64. See your dealer for
service.
Replacing Restraint System Parts
After a Crash
{WARNING:
A crash can damage the restraint systems in your
vehicle. A damaged restraint system may not
properly protect the person using it, resulting in
serious injury or even death in a crash. To help
make sure your restraint systems are working
properly after a crash, have them inspected and
any necessary replacements made as soon as
possible. If the vehicle has been in a crash, do you need new
safety belts or LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary. But
the safety belt assemblies that were used during any
crash may have been stressed or damaged. See your
dealer to have the safety belt assemblies inspected or
replaced.
If the vehicle has the LATCH system and it was being
used during a crash, you may need new LATCH system
parts.
New parts and repairs may be necessary even if the
safety belt or LATCH system (if equipped), was not
being used at the time of the crash.
If an airbag inflates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
Have the safety belt pretensioners checked if the
vehicle has been in a crash, if the airbag readiness light
stays on after the vehicle is started, or while you are
driving. See
Airbag Readiness Lighton page 4‑26.

Do not keep driving if the oil pressure is low. The
engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.

damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule for changing engine oil.
This light comes on briefly while starting the engine. If it
does not, have the vehicle serviced by your dealer.
If the system is working normally the indicator light then
goes off. If the light comes on and stays on, it means that oil is
not flowing through the engine properly. The vehicle
could be low on oil and it might have some other
system problem.

Engine Air Cleaner/Filter
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter at the scheduled
maintenance intervals and replace it at the first oil
change after each 80 000 km (50,000 mi) interval. See
Scheduled Maintenance
on page 7‑3for more
information. If you are driving in dusty/dirty conditions,
inspect the filter at each engine oil change. Replace
filter if appears dusty or dirty.
How to Inspect the Engine Air Cleaner/
Filter
See Engine Compartment Overviewon page 6‑14for
the location of the engine air cleaner/filter.
To inspect the air cleaner/filter remove the filter from the
vehicle and lightly shake the filter to release loose dust
and dirt. If the filter remains caked with dirt, a new filter
is required. Never use compressed air to clean the filter.
Because this operation can be a little difficult, you may
choose to have this done at the dealer service
department.

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.

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.
