Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if the
key is in the ON/RUN and the light is not on.
The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if the battery has recently been
replaced or if the battery has run down.
The diagnostic system is designed to evaluate
critical emission control systems during normal
driving. This can take several days of routine
driving. If this has been done and the vehicle still
does not pass the inspection for lack of OBD II
system readiness, your dealer/retailer can prepare
the vehicle for inspection.
Oil Pressure Light
If the vehicle has low
engine oil pressure, this
light will stay on after
the engine is started, or
come on while driving.
This indicates that the engine is not receiving enough
oil. The engine could be low on oil, or could have some
other oil problem. Have it xed immediately by your
dealer/retailer.
The oil light could also come on in three other situations:
When the ignition is on but the engine is not
running, the light will come on as a test to show it is
working. The light will go out when the ignition is
turned on. If it does not come on with the ignition
on, there may be a problem with the fuse or
bulb. Have it xed right away.
If the vehicle comes to a hard stop, the light may
come on for a moment. This is normal.
3-34

{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance can
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
Change Engine Oil Light
The vehicle may have an
engine oil life system that
indicates when the oil
needs to be changed.
When the change engine oil light comes on, it means
that the engine oil needs to be changed.Once the engine oil has been changed, the engine oil
life system must be reset. After reset, the change engine
oil light goes out.
SeeEngine Oil Life System on page 5-18,Scheduled
Maintenance on page 6-4andEngine Oil on page 5-16
for more information.
Fog Lamp Light
For vehicles with this
feature, the fog lamps light
will come on when the
fog lamps are in use.
The light will go out when the fog lamps are turned off.
SeeFog Lamps on page 3-15for more information.
3-35

Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle’s tires so they actually ride on the
water. This can happen if the road is wet enough and
you are going fast enough. When your vehicle is
hydroplaning, it has little or no contact with the road.
There is no hard and fast rule about hydroplaning.
The best advice is to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather driving tips
include:
Allow extra following distance.
Pass with caution.
Keep windshield wiping equipment in good shape.
Keep the windshield washer uid reservoir lled.
Have good tires with proper tread depth. SeeTires
on page 5-51.
Turn off cruise control.
Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid:Reservoir full?
Windows clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All levels checked?
Lamps:Do they all work and are lenses clean?
Tires:Are treads good? Are tires inated to
recommended pressure?
Weather and Maps:Safe to travel?
Have up-to-date maps?

Engine Oil
If the engine oil pressure
light comes on, check the
engine oil level right away.
The oil pressure light is on the instrument panel cluster.
SeeOil Pressure Light on page 3-34. Check the
engine oil level regularly; this is an added reminder.
Checking Engine Oil
It is a good idea to check the engine oil level at each
fuel ll. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-14for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If this is not done, the
oil dipstick might not show the actual level.
2. Pull the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it
again, keeping the tip down and check the level.
When to Add Engine Oil
If the oil is below the MIN (minimum) mark on the
dipstick, add at least one quart/liter of the recommended
oil. This section explains what kind of oil to use. For
engine oil crankcase capacity, seeCapacities and
Specifications on page 5-93.
Notice:Do not add too much oil. If the engine has
so much oil that the oil level gets above the
upper mark that shows the proper operating range,
the engine could be damaged.
SeeEngine Compartment Overview on page 5-14for
the location of the engine oil ll cap.
Add enough oil to put the level somewhere in the proper
operating range. Push the dipstick all the way back in
when through.

Dust may be removed from small buttons and knobs
using a small brush with soft bristles.
Products that remove odors from the vehicle’s
upholstery and clean the vehicle’s glass can be obtained
from your dealer/retailer.
Do not clean the vehicle using:
A knife or any other sharp object to remove a soil
from any interior surface.
A stiff brush. It can cause damage to the vehicle’s
interior surfaces.
Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
the interior and does not improve the effectiveness
of soil removal.
Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks and
attracts dirt. For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide. Use
only mild, neutral-pH soaps.
Too much cleaner that saturates the upholstery.
Organic solvents such as naptha, alcohol, etc. that
can damage the vehicle’s interior.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be used
on oor carpet and carpeted oor mats. For any soil,
always try to remove it rst with plain water or club soda.
Before cleaning, gently remove as much of the soil as
possible using one of the following techniques:
For liquids: gently blot the remaining soil with a paper
towel. Allow the soil to absorb into the paper towel
until no more can be removed.
For solid dry soils: remove as much as possible and
then vacuum.
To clean:
1. Saturate a lint-free, clean white cloth with water or
club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub
toward the center. Continue cleaning, using a clean
area of the cloth each time it becomes soiled.
4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
5. If the soil is not completely removed, use a mild
soap solution and repeat the cleaning process
that was used with plain water.
