Q:Because I have a disability, I
have to get my vehicle
modied. How can I nd out
whether this will affect my
airbag system?
A:If you have questions, call
Customer Assistance. The phone
numbers and addresses for

Safety Belts
Now and then, check the safety belt
reminder light, safety belts,
buckles, latch plates, retractors, and
anchorages are all working
properly.
Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from doing its job. See your
dealer/retailer to have it repaired.
Torn or frayed safety belts may not
protect you in a crash. They can
rip apart under impact forces.
If a belt is torn or frayed, get a new
one right away.
Make sure the safety belt reminder
light is working. SeeSafety Belt
Reminders on page 3-30for more
information.Keep safety belts clean and dry.
SeeCare of Safety Belts on
page 5-86.

regularly scheduled maintenance or
replacement. Make sure the
airbag readiness light is working.
SeeAirbag Readiness Light
on page 3-31for 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,
seeWhat Makes an Airbag
Inflate? on page 1-50. See your
dealer/retailer for service.

often when pulling a trailer.
SeeScheduled Maintenance on
page 6-3for more information.
Things that are especially important
in trailer operation are automatic
transmission uid, engine oil,
axle lubricant, belts, cooling system
and brake system. It is a good
idea to inspect these before and
during the trip.

How to Reset the Engine Oil
Life System
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where you
change the oil prior to a CHANGE
ENGINE OIL SOON message being
turned on, reset the system.
To reset the Engine Oil Life System:
1. Turn the ignition to ON/RUN,
with the engine off.
2. Press the vehicle information
button until OIL LIFE
REMAINING displays.
3. Press and hold the set/reset
button until 100% is displayed.
You will hear three chimes
and the CHANGE ENGINE OIL
SOON message will go off.
4. Turn the key to LOCK/OFF.If the CHANGE ENGINE OIL SOON
message comes back on when
you start the vehicle, the engine oil
life system has not reset. Repeat
the procedure.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer’s warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your own
oil, be sure to drain all the oil from the
lter before disposal. Never dispose
of oil by putting it in the trash, pouring
it on the ground, into sewers, or into
streams or bodies of water. Recycle
it by taking it to a place that collects
used oil.
Engine Air Cleaner/Filter
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter at the
MaintenanceIIintervals and replace
it at the rst oil change after each
50,000 mile (80 000 km) interval.
SeeScheduled Maintenance
on page 6-3for more information.
If you are driving in dusty/dirty
conditions, inspect the lter at each
engine oil change.
SeeEngine Compartment Overview
on page 5-10for the location of
the engine air cleaner/lter.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/lter,
remove the lter from the vehicle and
lightly shake the lter (away from
vehicle) to release loose dust and
dirt. If the lter remains caked with
dirt, a new lter is required.

However, if your vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to
the low-beam headlamps may be
necessary if oncoming drivers ash
their high-beam headlamps at
you (for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
you take the vehicle to your
dealer/retailer for service.
Bulb Replacement

not listed in this section, contact
your dealer/retailer.
High Intensity Discharge
(HID) Lighting
{CAUTION
The low beam high intensity
discharge lighting system operates
at a very high voltage. If you try
to service any of the system
components, you could be
seriously injured. Have your
dealer/retailer or a qualied
technician service them.

Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire, if
the vehicle has one, for signs of
wear or damage. SeeWhen It Is
Time for New Tires on page 5-50
for more information.
Tires should be rotated every
5,000 to 8,000 miles (8 000 to
13 000 km). SeeScheduled
Maintenance on page 6-3.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like it
did when the tires were new.
Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.
