coolant temperature BUICK PARK AVENUE 2003 Owner's Manual

Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about 15
seconds between each try to help avoid draining
your battery or damaging your starter.
2. If it doesn't start within 10 seconds, hold your key in
START for about 10 seconds at a time until your
engine starts. Wait about 15 seconds between each
try.
3. If your engine still won't start (or starts but then
stops), it could be ¯ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
¯oor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
brie¯y but then stops again, do the same thing.
This time keep the pedal down for ®ve or six
seconds to clear the extra gasoline from the engine.
After waiting about 15 seconds, repeat the normal
starting procedure.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you don't, your engine
might not perform properly.
Engine Coolant Heater
If your vehicle has this feature, in very cold weather,
0ÉF (-18ÉC) or colder, the engine coolant heater
can help. You'll get easier starting and better fuel
economy during engine warm-up. Usually, the coolant
heater should be plugged in a minimum of four
hours prior to starting your vehicle. At temperatures
above 32ÉF (0ÉC), use of the coolant heater is not
required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on the
passenger's side of the vehicle, above the headlamp
assembly.
2-23

3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a ®re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you don't, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transaxle Operation
Your automatic transaxle has a shift lever located on
the steering column.
PARK (P):This position locks your front wheels. It's the
best position to use when you start your engine
because your vehicle can't move easily.

·If there's a brake system problem that is speci®cally
related to traction control, the traction control
system will turn off, the warning light will come on
and the chime will sound.
·If the traction control system is affected by an
engine-related problem, the system will turn off, the
warning light will come on and the chime will sound.
If the traction control system warning light comes on and
stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature Gage
This gage measures the
temperature of the
vehicle's engine. If the
pointer moves into
the shaded area, the
engine is too hot. A
temperature indicator light
will turn on and a chime
will sound.
If you have been operating your vehicle under normal
driving conditions, and the temperature indicator
light comes on, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
Malfunction Indicator Lamp
Service Engine Soon Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
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, your emission controls
may not work as well, your fuel economy may not
be as good and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.

Driver Information Center (DIC)
Your vehicle may be equipped with a Driver Information
Center (DIC). The DIC will display information about
how your vehicle is functioning, as well as warning
messages if a system problem is detected.
The following buttons are
on the DIC control panel
located to the left of
the steering column:
ODO/TRIP (Odometer/Trip):Use this button to display
your total and trip miles.
FUEL INFO (Information):Press this button to display
fuel information such as fuel used, fuel range and
fuel economy.GAGE INFO (Information):Use this button to display
oil pressure, oil life, coolant temperature, tire pressure
and battery information.
RESET:This button, used along with other buttons, will
reset system functions.
ENG/MET (English/Metric):Use this button to change
the display between English and metric units.
DIC Controls and Displays
When you turn the ignition on, the DIC will display your
driver number. You can have your dealer program
your name to appear on this display line. See your
dealer for more information.
The system will then perform a status check and display
any messages if a problem is detected. If there are
no problems detected, the display will return to the mode
selected by that driver the last time the ignition was
turned off.
If a problem is detected, a diagnostic message will
appear in the display. The following pages will show the
messages you may see on the DIC display.
The message center is continuously updated with the
vehicle's performance status.
3-43

ODO/TRIP (Odometer/Trip)
When this button is pressed, the display will show the
total mileage, and TRIP 1 or TRIP 2 miles. TRIP 1
and TRIP 2 will display the miles traveled since the last
reset. To reset the trip odometer, press the ODO/TRIP
button until the trip miles are shown in the DIC
display, then press the RESET button. The trip odometer
will now accumulate miles until the next reset.
FUEL INFO (Information)
Fuel Used:Press the FUEL INFO button until the
display shows FUEL USED. This display will show you
how much fuel has been used since the last reset.
To learn how much fuel is used from a new starting
point, press the RESET button while the fuel used
is displayed in the DIC.
Fuel Range:Press the FUEL INFO button until the
display shows FUEL RANGE. The fuel range will
calculate the remaining distance you can drive without
refueling. This calculation is based on the average
fuel economy for the last 25 miles (40.25 km) driven,
and the fuel remaining in the fuel tank. The RESET
button does not function in this mode.
Instantaneous Fuel Economy:Press the FUEL INFO
button until the display shows FUEL ECONOMY
INST. Instantaneous fuel economy varies with yourdriving conditions, such as acceleration, braking and the
grade of the road being traveled. The RESET button
does not function in this mode.
Average Fuel Economy:Press the FUEL INFO button
until the display shows FUEL ECONOMY AVERAGE.
Average fuel economy is viewed as a long term
approximation of your overall driving conditions. To
learn the average fuel economy from a new starting
point, press the RESET button while the average fuel
economy is displayed in the DIC.GAGE INFO (Information)
Coolant Temperature:Press the GAGE INFO button
until COOLANT TEMP appears in the display. If there are
no problems detected with the temperature, COOLANT
TEMP NORMAL will appear in the display. If the
temperature is too high, COOLANT TEMP HOT will
appear in the display. If you see the COOLANT TEMP
HOT message, your engine is overheated. You should
pull off the road, stop your vehicle and turn off your
engine as soon as possible. This manual explains what to
do. See
Engine Overheating on page 5-27.
Tire Pressure:Press the GAGE INFO button until
TIRE PRESSURE appears in the display. TIRE
PRESSURE NORMAL is displayed when the Check
Tire Pressure System believes your vehicle's tire
pressures are normal. If a potential tire pressure
problem is detected, the display will show TIRE
PRESSURE LOW.

A 50/50 mixture of clean, drinkable water and
DEX-COOLžwill:
·Give freezing protection down to-34ÉF (-37ÉC).
·Give boiling protection up to 265ÉF (129ÉC).
·Protect against rust and corrosion.
·Help keep the proper engine temperature.
·Let the warning lights and gages work as
they should.
Notice:When adding coolant, it is important that
you use only DEX-COOLž(silicate-free) coolant.
If coolant other than DEX-COOLžis added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the engine
coolant will require change sooner -- at 30,000 miles
(50,000 km) or 24 months, whichever occurs ®rst.
Damage caused by the use of coolant other
than DEX-COOL
žis not covered by your new vehicle
warranty.
What to Use
Use a mixture of one-halfclean, drinkable waterand
one-half DEX-COOLžcoolant which won't damage
aluminum parts. If you use this coolant mixture you don't
need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle's coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch ®re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
žcoolant.
Notice:If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost wouldn't be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Notice:If you use the proper coolant, you don't
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
5-25

{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
Occasionally check the coolant level in the radiator. For
information on how to add coolant to the radiator,
see
Cooling System on page 5-30.
Radiator Pressure Cap
Notice:Your radiator cap is a pressure-type cap
and must be tightly installed to prevent coolant loss
and possible engine damage from overheating.
Be sure the arrows on the cap line up with the
over¯ow tube on the radiator ®ller neck.
See
Engine Compartment Overview on page 5-12for
more information on location.
Engine Overheating
You will ®nd a warning light about a hot engine, as well
as a coolant temperature gage, on your instrument
panel.
