2003 Buick Park Avenue Owner ManualM

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.

Outside Convex Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Outside Automatic Dimming
Heated Mirror
If you have this feature, the driver's side outside
rearview mirror will adjust for the glare of headlamps
behind you. This feature is controlled using the on and
off settings on the automatic dimming rearview mirror.
See ªAutomatic Dimming Rearview Mirrorº or ªAutomatic
Dimming Rearview Mirror with Compassº earlier in
this section.If you have this feature, the left and right outside mirrors
are also heated when you activate the rear window
defogger. See ªRear Window Defoggerº under
Dual Automatic Climate Control System on page 3-22.
Both outside mirrors can be folded forward or rearward.
In the rearward position, they will fold ¯ush with the
vehicle. This feature is particularly useful in automatic
car washes.
OnStaržSystem
Your vehicle may have this feature. OnStaržuses
global positioning system (GPS) satellite technology,
wireless communications, and state of the art call
centers to provide you with a wide range of safety,
security, information and convenience services.
A complete OnStar
žuser's guide and the terms and
conditions of the OnStaržSubscription Service
Agreement are included in your OnStarž-equipped
vehicle's glove box literature.

Horn
Press on the center area of the steering wheel to sound
the horn.
Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. You can also raise it to the highest
level to give your legs more room when you exit
and enter the vehicle.
The lever that allows you to tilt the steering wheel is
located on the left side of the steering column.
To tilt the wheel, hold the
wheel and pull the lever
toward you. Then move the
steering wheel to a
comfortable position and
release the lever to
lock the wheel in place.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
·Turn and Lane-Change Signals
·Headlamp High/Low-Beam Changer
·Flash-to-Pass
·Windshield Wipers
·Windshield Washer
·Cruise Control
For information on the exterior lamps, see
Exterior
Lamps on page 3-12.

Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or high
to low, pull the turn signal lever toward you, then
release it.
When the high beams are
on, a light on the
instrument panel cluster
will also be on. If your
vehicle is equipped with
HUD, this light will
also appear in the
display area.
Flash-To-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
It works even if your headlamps are off.
To use it, pull the turn signal lever toward you, but not
so far that you hear a click.
If your headlamps are off or on low beam, your
high-beam headlamps will turn on. They'll stay on as
long as you hold the lever toward you and the
high-beam indicator on the instrument panel cluster will
come on. Release the lever to turn the high-beam
headlamps off.
Windshield Wipers
You control the windshield wipers by turning the band
marked WIPER.
For a single wiping cycle, turn the band to MIST. Hold it
there until the wipers start, then let go. The wipers
will stop after one cycle. If you want more cycles, hold
the band on MIST longer.
Use the delay position to set the wiper speed for a long
or short delay between wipes. This can be very
useful in light rain or snow. Turn the band to choose the
delay time. The closer to LO, the shorter the delay
between wipes.
For steady wiping at low speed, turn the band away
from you to the LO position. For high-speed wiping, turn
the band further, to HI. To stop the wipers, turn the
band to OFF.
Remember that damaged wiper blades may prevent you
from seeing well enough to drive safely. To avoid
damage, be sure to clear ice and snow from the wiper
blades before using them. If they're frozen to the
windshield, carefully loosen or thaw them. If your blades
become damaged, get new blades or blade inserts.
Heavy snow or ice can overload your wiper motor. A
circuit breaker will stop the motor until it cools.
Clear away snow or ice to prevent an overload.

3-12

Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
®rst sold in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
Twilight Sentinel
ž, so be sure it isn't covered.
The DRL system will make your high-beam headlamps
come on at reduced brightness in daylight when the
following conditions are met:
·The ignition is on,
·the exterior lamps control is off, and
·the transaxle is not in PARK (P).
When DRL are on, only your high-beam headlamps will
be on. The parking lamps, taillamps, sidemarker and
other lamps won't be on. Your instrument panel won't be
lit up either.When it's dark enough outside, your high-beam
headlamps will change to low-beam headlamps at full
brightness. The other lamps that turn on with your
headlamps will also turn on. When it's bright enough
outside, the regular lamps will turn off, and your
high-beam headlamps change to the reduced brightness
of DRL.
To idle your vehicle with the DRL off, shift the transaxle
into PARK (P). The DRL will stay off until you shift
out of PARK (P).
To turn off all exterior lighting at night when you are
parked, turn off the exterior lamp control and slide the
Twilight Sentinel
žcontrol all the way to the left.
When released, the control will return to the Twilight
Sentinel
žminimum delay position and the lights will
turn off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps
The cornering lamps come on when the headlamps or
parking lamps are on and you signal a turn with the
multifunction lever. They provide more light for
cornering.
3-13

Twilight Sentinelž
Twilight Sentinelžturns
your headlamps on and off
by sensing how dark it
is outside.
To operate this feature, slide the control to any position
to vary the lamp timeout.
You can set the delay time from only a few seconds to
three minutes. If you move the control all the way to
MAX, your lamps will remain on for three minutes after
you turn off your engine. If you move the control
almost all the way in the other direction, so it's just on,
the lamps will go off quickly when you turn off your
engine. Sliding the control to OFF, turns off the Twilight
Sentinel
žfeature.
Light Sensor
Your Twilight Sentinelžand DRL work with the light
sensor on top of the instrument panel. Don't cover it up.
If you do, it will sense ªdarkº and the headlamps will
come on.
Interior Lamps
Instrument Panel Brightness
Instrument panel light brightness can be adjusted by
turning the exterior lamps control counterclockwise and
clockwise.
Courtesy Lamps
When any door is opened, several lamps go on. They
make it easy for you to enter and leave your vehicle.
You can also turn these lamps on by turning the exterior
lamps control clockwise all the way past the normal
stop.
Entry Lighting
When you open either front door or press the button
with the unlock symbol on the remote keyless entry
transmitter, the lamps inside your vehicle will turn on.
These lamps will turn off after about 40 seconds. These
lamps will also turn off if you start the engine or
activate the power door locks.
