Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures
that emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.This light comes on when the
ignition is on, but the engine is not
running, as a check to show it
is working. If it does not, have the
vehicle serviced by your
dealer/retailer.
If the check engine light comes on
and stays on, while the engine
is running, this indicates that there
is an OBD II problem and service
is required.
Malfunctions often are indicated by
the system before any problem
is apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system
assists the service technician in
correctly diagnosing any
malfunction.
Notice:If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
3-30 Instrument Panel

the vehicle’s fuel economy might
not be as good, and the engine
might not run as smoothly.
This could lead to costly repairs
that might not be covered by
the vehicle warranty.
Notice:Modications made to
the engine, transmission,
exhaust, intake, or fuel system of
the vehicle or the replacement
of the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle’s emission
controls and can cause this light
to come on. Modications to
these systems could lead
to costly repairs not covered by
the vehicle warranty. This
could also result in a failure to
pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications
on page 5-3.This light comes on during a
malfunction in one of two ways:
Light Flashing:A misre condition
has been detected. A misre
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the
amount of cargo being hauled
as soon as it is possible.
If the light continues to ash, when
it is safe to do so, stop the
vehicle. Find a safe place to park
the vehicle. Turn the key off, wait at
least 10 seconds, and restart the
engine. If the light is still ashing,
follow the previous steps and
see your dealer/retailer for service
as soon as possible.Light On Steady:An emission
control system malfunction has been
detected on the vehicle. Diagnosis
and service might be required.
An emission system malfunction
might be corrected by:
Make sure the fuel cap is fully
installed. SeeFilling the Tank
on page 5-7. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel
to evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn
the light off.
If the vehicle has been driven
through a deep puddle of
water, the vehicle’s electrical
system might be wet. The
condition is usually corrected
when the electrical system dries
out. A few driving trips should
turn the light off.

Your Driving, the
Road, and the Vehicle
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
Avoid fast starts and accelerate
smoothly.
Brake gradually and avoid abrupt
stops.
Avoid idling the engine for long
periods of time.
When road and weather
conditions are appropriate, use
cruise control, if equipped.
Always follow posted speed limits
or drive more slowly when
conditions require.
Keep vehicle tires properly
inated.
Driving Your Vehicle 4-1

And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition of
the road, whether it is wet, dry, or
icy; tire tread; the condition of
the brakes; the weight of the vehicle;
and the amount of brake force
applied.
Avoid needless heavy
braking. Some people drive in
spurts — heavy acceleration
followed by heavy braking — rather
than keeping pace with traffic.
This is a mistake. The brakes might
not have time to cool between
hard stops. The brakes will wear out
much faster with a lot of heavy
braking. Keeping pace with
the traffic and allowing realistic
following distances eliminates a lot
of unnecessary braking. That
means better braking and longer
brake life.
If the vehicle ever loses electrical
power while it is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,the pedal could get harder to push
down. If the vehicle loses electrical
power, there will still be some
power brake assist but it will be
used when the brake is applied.
Once the power assist is used up, it
can take longer to stop, the brake
pedal will be harder to push,
and you might experience longer
pedal travel.
Adding non-dealer/non-retailer
accessories can affect vehicle
performance. SeeAccessories and
Modifications on page 5-3.
Hill Start Assist
This vehicle has a Hill Start Assist
(HSA) feature, which may be
useful when the vehicle is stopped
on a grade. This feature is
designed to prevent the vehicle from
rolling, either forward or rearward,
during vehicle drive off. After
the vehicle is stopped on an incline,
push the brake pedal completely
to the oor to activate Hill StartAssist. When the system activates,
a chime will sound and the HSA
ON message will be displayed.
Letting off the brake pedal slightly or
applying the accelerator pedal to
disengage Hill Start Assist gives the
driver two seconds to pull forward
or back up before the vehicle
starts to roll. Lightly ease off the
brake pedal to disengage Hill
Start Assist. The brakes will
automatically be held for a maximum
of two seconds while the driver
switches from applying the brakes
to pushing the accelerator pedal.
When Hill Start Assist is active, the
driver might experience a “hard
pedal.” This is normal and does not
affect safe brake operation.
On steeper hills, Hill Start Assist will
only activate if the driver tries to
move the vehicle up the hill. It will
not activate if the vehicle is in a
drive gear and facing downhill or if
the vehicle is facing uphill and
in R (Reverse).
