When the Light Flashes First and Then is
Solid
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light will ash for
about a minute and then stay on solid for the remainder
of the ignition cycle. This sequence will repeat with
every ignition cycle. SeeTire Pressure Monitor System
on page 5-70for more information.
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 makes
sure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.
The check engine light
comes on to indicate that
there is an OBD II
problem and service is
required.Malfunctions often are indicated by the system before
any problem is apparent. This can prevent more serious
damage to your vehicle. This system is also designed
to assist your service technician in correctly diagnosing
any malfunction.
Notice:If you keep driving your vehicle with this
light on, after a while, the emission controls
might not work as well, your 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 your warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of
your vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This could
also result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 5-4.

Economy)
AV SPEED (Average Vehicle Speed)
OIL LIFE (Engine Oil Life System)
Tire Pressure
TRIP A or TRIP B:Press the information button until
TRIP A or TRIP B display. These modes show the
current distance traveled since the last reset for each
trip odometer in either miles (mi) or kilometers (km).
Both odometers can be used at the same time.
To reset the trip odometer to zero, press and hold the
enter button for a few seconds while the desired
trip odometer is displayed.
FUEL RANGE:Press the information button until FUEL
RANGE displays. This mode shows the remaining
distance you can drive without refueling in either
miles (mi) or kilometers (km). It is based on fuel
economy and the fuel remaining in the tank.
When the fuel level is low, FUEL RANGE LOW displays.
The fuel economy data used to determine fuel range
is an average of recent driving conditions. As your
driving conditions change, this data is gradually updated.
The FUEL RANGE mode cannot be reset.MPG (L/100 KM) AVG (Average):Press the
information button until MPG (L/100 KM) AVG displays.
This mode shows how many miles per gallon (mpg)
or liters per 100 kilometers (L/100 km) your vehicle is
getting based on current and past driving conditions.
To reset the average fuel economy, press and hold the
enter button while MPG (L/100 KM) AVG is displayed.
Average fuel economy is then be calculated starting
from that point. If the average fuel economy is not reset,
it is continually updated each time you drive.
MPG (L/100 KM) INST (Instantaneous):Press the
information button until MPG (L/100 KM) INST displays.
This mode shows the current fuel economy at a
particular moment and changes frequently as driving
conditions change. This mode shows the instantaneous
fuel economy in miles per gallon (mpg) or liters per
100 kilometers (L/100 km). Unlike average fuel
economy, this screen cannot be reset.
AV (Average) SPEED:Press the information button
until AV SPEED displays. This mode shows the vehicle’s
average speed in miles per hour (mph) or kilometers
per hour (km/h).
To reset the average vehicle speed, press and hold the
enter button while AV SPEED is displayed.

DIC Vehicle Personalization
The following personalization options may appear on
your vehicle’s audio display by pressing the MENU
button.The default settings for the features were set when your
vehicle left the factory, but may have been changed
from their default state since that time.
OIL LIFE RESET:When this option is displayed, you
can reset the engine oil life system. To reset the system,
seeEngine Oil Life System on page 5-24.
UNITS:When UNITS appears on the display, press the
enter button to move between METRIC (default in
Canada) or ENGLISH (default in United States). When
you have made your choice, press the MENU button
to record your selection.
If you choose English, all information will be displayed
in English units.
If you choose metric, all information will be displayed in
metric units.
The unit measurement will also change the trip
odometer, temperature, and average fuel economy
displays.
TIRE LEARN?:This option is available on vehicles
without the Remote Keyless Entry (RKE) system. After
rotating the tires or after replacing a tire or sensor,
the Tire Pressure Monitor System (TPMS) must re-learn
the tire positions. To re-learn the tire positions, see
Tire Pressure Monitor System on page 5-70. SeeTire
Inspection and Rotation on page 5-77andDIC Warnings
and Messages on page 3-46for more information.

CAUTION: (Continued)
Flowing or rushing water creates strong
forces. Driving through owing water could
cause your vehicle to be carried away. If this
happens, you and other vehicle occupants
could drown. Do not ignore police warnings
and be very cautious about trying to drive
through owing water.
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 5-60.
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?

Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. 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 you do not do this,
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.
