2003 PONTIAC GRAND PRIX power steering

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? 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.
B (LOCK): This position locks the ignition, steering
wheel and transaxle. It’s a theft-deterrent feature. It’s also
the only position from which you can remove the key.
C (OFF): This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the
steering wheel like LOCK. Use
OFF if you must have
the vehicle pushed or towed.
D (RUN): This position is where the key returns to after
you start the vehicle. With the engine
off, you can use
RUN to display some of the warning and indicator lights.
E (START): This position starts the engine.
A warning chime will sound
if you open the driver’s door
while the ignition is in
OFF, LOCK or ACCESSORY
and the key is in the ignition.
Retained Accessory Power (RAP)
With Retained Accessory Power, (RAP), the power
windows, audio system and sunroof will continue to work
up to
10 minutes after the ignition key is turned to
OFF and none of the doors are opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position - that’s a
safety feature. To restart while you’re already moving,
use NEUTRAL
(N) only.
Nofice: Don’t try to shift to PARK (P) if your
vehicle is moving.
If you do, you could damage the
transaxle. Shift to
PARK (P) only when your
vehicle is stopped.
Shift Lock Release
This vehicle is equipped with an electric shift lock
release system. The shift lock release is designed to
do the following:
Prevent ignition key removal unless the shift lever is
in PARK (P) with the shift lever button fully released.
Prevent movement of the shift lever out of PARK (P)
unless the ignition is in a position other than
OFF or
LOCK. The shift lock release is always functional
except in the case
of a dead or low voltage
(less than
9 V) battery.

Disabling the Theft-Deterrent Feature
Enter your secret code as follows; pause no more than
15 seconds between steps:
1. Turn the ignition on.
2. Turn the radio off.
3. Press the 1 and 4 pushbuttons at the same time.
Hold them down until
SEC shows on the display.
4. Press MIN and 000 will appear on the display.
5. Press MIN again to make the last two digits agree
with your code.
6. Press HR to make the first one or two digits agree
with your code.
7. Press AM/FM after you have confirmed that the
code matches the secret code you have written
down. The display will show
---, indicating that the
radio is no longer secured.
If the code entered is incorrect,
SEC will appear on the
display. The radio will remain secured until the correct
code is entered.
When battery power is removed and later applied to
a
secured radio, the radio won’t turn on and LOC will
appear on the display.
To unlock a secured radio, see “Unlocking the
Theft-Deterrent Feature After a Power
Loss” earlier in
this section.
Audio Steering Wheel Controls
If your vehicle has this feature, you can control certain
radio functions using the buttons on your steering
wheel.
PRESET: Press this button to play the stations you
have programmed on the radio preset pushbuttons.
The radio will go to a preset station, play for a few
seconds, then go to the next station. When a cassette
tape is playing, press this button to change tape
sides. Press this button again to stop scanning the
preset stations.

Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer
but it will take much more effort.
Variable Effort Steering
If your vehicle has this steering system, the system
provides less steering effort for parking and when driving
at speeds below
20 mph (32 km/h). Steering effort will
increase at higher speeds for improved road feel.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves. The
traction of the tires against the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels. If there’s no traction, inertia will keep the
vehicle going in the same direction. If you’ve ever tried to
steer a vehicle on wet ice, you’ll understand this. The
traction you can get in a curve depends on the
condition of your tires and the road surface, the angle at
which the curve is banked, and your speed. While you’re
in a curve, speed is the one factor you can control.
Suppose you’re steering through a sharp curve. Then you
suddenly accelerate. Both control systems
- steering
and braking
- have to do their work where the tires meet
the road. Unless you have four-wheel anti-lock brakes,
adding the hard braking can demand
too much of those
places. You can lose control.
The same thing can happen
if you’re steering through a
sharp curve and you suddenly accelerate. Those two
control systems
- steering and acceleration - can
overwhelm those places where the tires meet the
road and make you lose control. See Traction Control
System (TCS) on page
4- 10 or Enhanced Traction
System (ETS)
on page 4- I 1.
What should you do if this ever happens? Ease up on
the brake or accelerator pedal, steer the vehicle the way
you want it
to go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds
are based
on good weather and road conditions.
Under less favorable conditions you’ll want to
go slower.
