2003 - Regal Owner Manual

Ignition Positions
With the ignition key in the ignition, you can turn the key
tofive different positions:
A (ACCESSORY):This position lets you use the radio
and windshield wipers when the engine is off. To
use ACCESSORY, push in the key and turn it toward
you. Your steering wheel will stay locked.
B (LOCK):This is the only position in which you can
insert or remove the key. This position locks the ignition,
steering wheel and transaxle. It’s a theft-deterrent
feature.Notice:If your key seems stuck in LOCK and you
can’t turn it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the steering
wheel left and right while you turn the key hard.
Turn the key only with your hand. Using a tool
to force it could break the key or the ignition switch.
If none of these works, then your vehicle needs
service.
C (OFF):This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the
steering wheel. Use OFF if you must have your vehicle
pushed or towed.
D (RUN):This position is where the key returns to after
you start your vehicle. With the engine off, you can
use RUN to display some of your warning and indicator
lights.
E (START):This position starts your engine.
A warning chime will sound if you open the driver’s door
when the ignition is in OFF, LOCK or ACCESSORY
and the key is in the ignition.
Retained Accessory Power (RAP)
With Retained Accessory Power (RAP), your power
windows and audio system will continue to work for up
to 10 minutes after the ignition key is turned to OFF
and before any of the doors are opened.

Horn
Press the horn symbols on your steering wheel pad to
sound the horn.
Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. You can 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.
Then move the steering
wheel to a comfortable
position and release
the lever to lock the
wheel into place.
Turn Signal/Multifunction Lever
The lever located 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
3-5
2003 - Regal OM

Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal the 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 a little,
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 dash will come on. Release
the lever to return to normal operation.
Windshield Wipers
To operate the windshield wipers turn the band located
on the multifunction lever upward or downward.
WIPER:Turn this band to control the windshield wipers.
OFF:Turn the band to OFF to turn off the windshield
wipers.
LO (Low Speed):Turn the band away from you to LO
and past the delay settings for steady wiping at low
speed.HI (High Speed):Turn the band away from you, to HI,
and past the delay settings for wiping steady at high
speed.
(Delayed Wiping):Turn the band away from you, just
past OFF, to one of thefive sensitivity settings, to
choose the delayed wiping cycle. The further the band
is turned upward, toward LO, the shorter the delay
will be. Use this setting for light rain or snow.
MIST:Turn the band to MIST for a single wiping cycle.
Hold it until the windshield wipers start. Then let it
go. The windshield wipers will stop after one wipe. If
you want more wipes, hold the band on MIST longer.
Be sure to clear ice and snow from the windshield wiper
blades before using them. If they are frozen to the
windshield, carefully loosen or thaw them. If your blades
do become worn or damaged, get new blades or
blade inserts.
Heavy snow or ice can overload your wipers. A circuit
breaker will stop them until the motor cools. Clear away
snow or ice to prevent an overload.

Windshield Washer
At the top of the multifunction lever, there is a paddle
with the word PUSH on it. To spray washerfluid on the
windshield, push the paddle. The wipers will run for
several sweeps and then either stop or return to your
preset speed. SeeWindshield Washer Fluid on
page 5-38.
{CAUTION:
In freezing weather, don’t use your washer
until the windshield is warmed. Otherwise the
washer fluid can form ice on the windshield,
blocking your vision.
The LOW WASH light on
your instrument panel
cluster will come on when
thefluid level is low.
Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long
trips. Cruise control does not work at speeds below
about 25 mph (40 km/h).
When you apply your brakes, the cruise control
shuts off.
{CAUTION:
•Cruise control can be dangerous where
you can’t drive safely at a steady speed.
So, don’t use your cruise control on
winding roads or in heavy traffic.
•Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
needless wheel spinning, and you could
lose control. Don’t use cruise control on
slippery roads.

=REAR:Press this button to turn the rear window
defogger on. It will turn off after about 15 minutes. If you
turn it on again, the rear defogger will only run for
about seven and one half minutes before turning off.
You can also turn it off by pressing the button again.
Do not drive the vehicle until all the windows are clear.
Notice:Don’t use a razor blade or something
else sharp on the inside of the rear window. If you
do, you could cut or damage the defogger and
the repairs would not be covered by your warranty.
Do not attach a temporary vehicle license, tape,
a decal or anything similar to the defogger grid.
Outlet Adjustment
Open and close the air
outlets, or adjust the
direction of the airflow by
moving the levers in
the center of each outlet.
Operation Tips
•Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block theflow of air into your vehicle.
•Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
•If the airflow seems low when the fan is at the
highest setting, the passenger compartment
airfilter, if equipped, may need to be replaced. For
more information, seePassenger Compartment
Air Filter on page 3-24andPart A: Scheduled
Maintenance Services on page 6-4.
Passenger Compartment Air Filter
The passenger compartment airfilter is located
underneath your hood below the windshield wiper arm,
on the passenger’s side (below the air inlet grille) of
the vehicle.
Thefilter traps most of the pollen from the air entering
the air conditioning module. Like your engine’s air
cleaner/filter, it may need to be changed periodically.
For information on how often to change the passenger
compartment airfilter, seePart A: Scheduled
Maintenance Services on page 6-4.
3-24
2003 - Regal OM

To change the passenger compartment airfilter, use the
following steps:
1. Turn off the ignition when the windshield wipers are
in the up position.
2. Raise the hood.
3. Disconnect the windshield washer pump hose from
the fender rail and air inlet grille.
4. Remove the hood weatherstrip from the passenger’s
side of the vehicle (peel back halfway to center).
5. Remove the three air inlet grille retainers.
6. Remove the air inlet grille.7. Remove the passenger
compartment airfilter.
8. Then replace the old airfilter with the new one. For
the type offilter to use, seeNormal Maintenance
Replacement Parts on page 5-93.
9. Reinstall the air inlet grille.
10. Reinstall the air inlet grille retainers.
11. Reattach the hood weatherstrip.
12. Reconnect the windshield washer pump hose to the
fender rail and air inlet grille.
13. Close the hood.
14. Return the windshield wipers to the park position.

The heavier the rain, the harder it is to see. Even if your
windshield wiper blades are in good shape, a heavy
rain can make it harder to see road signs and
traffic signals, pavement markings, the edge of the road
and even people walking.
It’s wise to keep your windshield wiping equipment in
good shape and keep your windshield washer tanklled
with washeruid. Replace your windshield wiper
inserts when they show signs of streaking or missing
areas on the windshield, or when strips of rubber start to
separate from the inserts.Driving too fast through large water puddles or even
going through some car washes can cause problems,
too. The water may affect your brakes. Try to avoid
puddles. But if you can’t, try to slow down before you
hit them.
{CAUTION:
Wet brakes can cause accidents.They won’t
work as well in a quick stop and may cause
pulling to one side.You could lose control of
the vehicle.
After driving through a large puddle of water
or a car wash, apply your brake pedal lightly
until your brakes work normally.

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 thatrst
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’llnd experienced and able service experts in GM
dealerships 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:
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 inated 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?
