Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn
on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none
of the above steps have made the light turn off,
have your retailer or qualified service center check the
vehicle. Your retailer has the proper test equipment and
diagnostic tools to
fix any mechanical or electrical
problems that may have developed.
Oil Pressure Warning Light
If you have a problem with
your oil, this light may
stay on after you start your
engine, or come on when
OIL you are driving.
A warning chime and the message
LOW OIL
PRESSURE may also come on.
These indicate that oil is not going through your engine
quickly enough to keep it cool. The engine could be low
on oil, or could have some other oil problem. Have it
fixed right away.
The oil light could also come on briefly when the
ignition is on but
the engine is not running. The light
will come on as a test to show
you it is working, but the
light will go out when you turn the ignition to START.
If
it doesn’t come on with the ignition on, you may have a
problem with the fuse or bulb. Have it fixed right away.

CAUTION:
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil
as soon as possible and have
your vehicle serviced.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Fuel Gage
When the ignition is on,
your fuel gage tells you
about how much fuel you
have left.
When you have less than
3 .O gallons (1 1.3 L) of fuel
remaining, the message LOW FUEL will be displayed
and a chime will
sound. You need to get more fuel
right away.
Press the FUEL button on the Driver Information Center
to turn off the warning.

Turn on the system by pressing any button except
RESET, ENTER or OFF. When you turn on the ignition,
the
DIC will be in the mode last displayed when the
engine was turned off. Keep in mind that this also
applies to the
OFF mode.
To turn off messages on the DIC (except LOW OIL
PRESSURE, LOW BRAKE FLUID, PARK BRAKE
SET and the hot engine warnings), press any button
on the DIC.
\ II
You will need to open the cover to access the control
buttons.
To open the cover, push the button located to
the right
of the cover.
To close the cover, push it down to its closed position.
Fuel Economy
The ECON button displays average fuel economy and
instantaneous fuel economy calculated for your specific
driving conditions.
Press ECON to display average fuel economy, such as:
25.2 AVG MI/GAL or 9.3 AVG WlOO KM
Press ECON again to display instantaneous fuel
economy, such as:
28 INST MUGAL or 8.4 INST WlOO KM
Press again to return to average fuel economy.
The average fuel economy is viewed as a long-term
approximation
of your overall driving conditions.
If you press RESET in this mode while you’re driving,
the system will begin figuring fuel economy from that
point
in time.

Fuel
Press FUEL to see how much fuel has been used since
you last pressed the reset button. The display will show
a reading such as:
10.4 GALLONS USED or 39.4 LITERS USED
To learn how much fuel will be used from a specific
starting point, first press FUEL to display fuel used,
then press RESET.
Don’t confuse fuel used with
the amount of fuel in your tank.
Fuel Range
RANGE calculates the remaining distance you can drive
without refueling. It’s based on fuel economy and the
fuel remaining in the tank. The display will show a
reading such as:
FUEL RANGE
235 MI or FUEL RANGE 378 KM
If the range is less than 50 miles (80 km), the display
will read LOW FUEL RANGE.
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.
Resetting fuel range causes the fuel economy data to be
updated immediately. To reset fuel range, press
RANGE, then RESET.
Average Speed
The calculation for average speed begins when SPEED
is reset. Press SPEED to display the average speed,
such as:
AVG SPEED 55 MPH or AVG SPEED 90 KM/H
To reset the average speed, press SPEED and
then RESET.
Engine
The ENG button scrolls through the following functions:
0 Oil pressure, such as:
OIL PRESSURE
40 PSI or OIL PRESSURE
276 Wa
0 Battery voltage, such as:
BATTERY
13.8 VOLTS
Transaxle fluid life, such as:
TRANS FLUID
LIFE 40%
This is an estimate of the transaxle fluid’s remaining
useful life. It will show 100% when the system is
reset after a transaxle fluid change. It
will alert you
to change your transaxle fluid on a schedule
consistent with your driving conditions.

Once you are moving on the freeway, make certain you
allow
a reasonable following distance. Expect to move
slightly slower at night.
When
you want to leave the freeway, move to the proper
lane well
in advance. If you miss your exit, do not,
under
any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed
is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must
start when you’re not fresh -- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in. Is your vehicle ready
for
a long trip? If you keep it
serviced and maintained, it’s ready to go,
If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts in
Aurora retail facilities all across North America. They’ll
be ready and willing to help if you need it.
Here are some things you can check before a trip:
a
a
a
a
Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a short
time to avoid
a major storm system?
Maps: Do you have up-to-date maps?

Cooling System
When you decide it's safe to lift the hood, here's what
you'll see:
B
A. Coolant Surge Tank with Pressure Cap
B. Two Electric Engine Cooling Fans
% CAUT IN:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure you. Keep hands, clothing and tools away from any underhood electric
fan.
If the coolant inside the coolant surge tank is boiling,
don't
do anything else until it cools down.

Engine Oil

OIL
If the CHECK OIL LEVEL
message
or the oil warning
light
on the instrument
panel comes on, it means
you need to check your
engine oil level right away.
For more information, see “Check Oil Level Message”
or “Oil Pressure Warning Light” in the Index. You
should check your engine oil level regularly; this
is
an added reminder.
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the 02 must
be warm and the vehicle must be on level ground.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstick
might not show the actual level.
Checking Engine Oil
Pull out 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 at or below the ADD line, then you’ll need
to add at least one quart of oil. But you must use the
right kind. This part explains what kind of oil to use. For
crankcase capacity, see “Capacities and Specifications”
in the Index.
