turn signal bulb PONTIAC GRAND PRIX 2003 Owners Manual

As you signal a turn or a lane change, if the arrow
flashes faster than normal, a signal bulb may be burned
out and other drivers won’t see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident.
If the arrows don’t go on at all when you signal
a turn, check for burned-out bulbs and then check the
fuse. See Fuses and Circuit Breakers
on page 5-97.
A chime will sound if you leave the turn signal on
for more than
3/4 mile (1.2 km).
Headlamp High/Low-Beam Changer
To change the headlamps from low-beam to high-beam,
or high to low, pull the multifunction lever
all the way
toward you. Then release it.
When the high beams are
on, this light on the
instrument panel cluster
will appear. While the high-beam headlamps are
on, the fog lamps will
not illuminate.
If your vehicle is equipped with the Head-Up-Display
(HUD), an arrow will appear in the display area to
indicate that the high beams are on. See Head-Up
Display
(HUD) on page 3-75 for more information.
Flash-to-Pass
This feature lets you use the high-beam headlamps to
signal a driver in front of you that you want to pass.
It works even
if your headlamps are in the automatic or
off position.
To use it, pull the turn signal lever toward you, then
release it.
If the headlamps are in the automatic position or on
low-beam, the high-beam headlamps will turn on and the
high-beam indicator on the instrument panel cluster
will come on. They will stay on as long as you hold the
lever toward you. Release the lever to return to the
initial position.
If your vehicle is equipped with the Head-Up-Display
(HUD), an arrow will appear in the display area to
indicate that the high beams are on.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your dealer. The arrows on your instrument
panel will flash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even
if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Your vehicle has bulb warning lights. When you plug a
trailer lighting system into your vehicle’s lighting
system, its bulb warning lights may not let you know
if
one of your lamps goes out. So, when you have a trailer
lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they’re all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you
if one
of your vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
If you have overdrive, you may have to drive in
THIRD (3) instead of AUTOMATIC OVERDRIVE (D).
Parking on Hills
1 -J really should not ,,rk yo^, wG,kle, with a
trailer attached, on a hill.
If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
