2005 PONTIAC GTO brake light

After shifting to FOURTH (4), you may downshift to a
lower gear if you prefer.
Notice:Forcing the shift lever into any gear except
FOURTH (4) when the 1 TO 4 SHIFT light comes
on may damage the transmission. Shift only from
FIRST (1) to FOURTH (4) when the light comes on.
This light will come on when:
•The engine coolant temperature is higher than
169°F (76°C),
•you are going 15 to 19 mph (24 to 31 km/h) and
•you are 21 percent throttle or less.
SeeOne-to-Four Shift Light (Manual Transmission) on
page 3-26andTrip Computer on page 3-33for more
information.
Parking Brake
To set the parking brake, pull up on the parking brake
handle without pressing the release button. If the ignition
is on, the brake system warning light will come on.
SeeBrake System Warning Light on page 3-27.
To release the parking brake, hold the regular brake
pedal down. Pull the parking brake handle up until you
can press the release button. Hold the release button
in as you move the brake handle all the way down.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.

Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. You may find it difficult to move
the shift lever out of PARK (P). This is called torque lock.
To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave the
driver’s seat. To find out how, seeShifting Into Park (P)
(Automatic Transmission) on page 2-24.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push your vehicle uphill. This should take some of
the pressure from the parking pawl in the transmission,
so you can move the shift lever out of PARK (P).
Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift lock
control system. You must fully apply your regular brakes
before you can press the button on the shift lever to
shift from PARK (P) while the ignition is ON. See
Automatic Transmission Operation on page 2-18.If you cannot shift out of PARK (P), ease pressure on
the shift lever by pushing it all the way into PARK (P)
while keeping the brake pedal down. Release the
shift lever button. Then move the shift lever out of
PARK (P), being sure to press the shift lever button.
Shift Lock Release
If you ever hold the brake pedal down but still cannot
shift out of PARK (P), try this:
1. Turn the ignition to LOCK to remove the key.
2. Remove the front console rubber insert, located in
front of the shift lever, by lifting upwards.
3. Remove the screw slightly to the right of the
front center.
4. Open the console storage compartment and pry
the console cover assembly from the console.
The cover is attached in six places.
5. Insert a tool into the opening in front of the shift
lever and move the yellow release lever forward.
6. Press the button on the shift lever to move lever out
of park.
7. Replace the console cap.
8. Have the vehicle fixed as soon as possible.

Daytime Running Lamps (DRL)
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.
The DRL system will make your low-beam headlamps
come on at a reduced brightness when the following
conditions are met:
•The ignition is on.
•The exterior lamp control is turned to AUTO and
the light sensor detects daytime light.
•The exterior lamp control is turned to the off
position.
•The parking brake is released.
•For vehicles with automatic transmissions, the shift
lever is not in PARK (P).
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps, and instrument panel lights will not
be illuminated unless you have turned the exterior lamps
control to the parking lamp or headlamp position.
The DRL system will remain off any time your vehicle is
in PARK (P) or the parking brake is engaged the first
time the ignition is turned on.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Automatic Headlamp System
When it is dark enough outside, your Automatic
Headlamp System will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps, and the
instrument panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor on the
top of the instrument panel under the defroster
grill. Make sure it is not covered, which will cause the
system to be on whenever the ignition is on.
The system may also be on when driving through a
parking garage, heavy overcast weather, or a tunnel.
This is normal.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately.
As with any vehicle, you should turn on the regular
headlamps when you need them.
The headlamps can be set to come on at different
levels. The sensitivity can be adjusted to Early, Normal,
or Late. SeeVehicle Personalization on page 2-30.
Leaving the headlamps and parking lamps on when the
engine is not running will eventually drain the battery.

Brake System Warning Light
This light will come on
when the ignition is turned
ON and when the
parking brake is applied.
If this light comes on and the Brake message appears
on the trip computer display while driving and the
parking brake is released, a fault with the brakes is
indicated. You should immediately stop the car on the
side of the road as carefully as possible. Do not proceed
until satisfied that braking is possible or that the
cause of the problem has been fixed.
A warning will chime if you attempt to drive off without
releasing the parking brake.
The Brake message will remain until the MODE button
on the trip computer is pressed, but the symbol will
remain until the problem is fixed.
This light will also come on to indicate low brake fluid.
Anti-Lock Brake System
Warning Light
This light will come on
briefly when the ignition is
turned to ON.
If the light does not come on then, have it fixed so it will
be ready to warn you if there is a problem.
If there is a problem with the anti-lock brake system,
this light will come on and the ABS Fault message will
appear on the trip computer display. See your GM
dealer for service. The vehicle’s brake system will still
operate without ABS.
The ABS Fault message will stay on until the MODE
button on the trip computer is pressed, but the light will
stay on until the problem is fixed.

Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-27.

{CAUTION:
Wet brakes can cause accidents. They will not
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.
Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the
water. This can happen if the road is wet enough and
you are going fast enough. When your vehicle is
hydroplaning, it has little or no contact with the road.Hydroplaning does not happen often. But it can if your
tires do not have much tread or if the pressure in one or
more is low. It can happen if a lot of water is standing
on the road. If you can see reflections from trees,
telephone poles, or other vehicles, and raindrops dimple
the water’s surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just is not a hard and fast rule about hydroplaning.
The best advice is to slow down when it is raining.
Driving Through Deep Standing Water
Notice:If you drive too quickly through deep
puddles or standing water, water can come in
through your engine’s air intake and badly damage
your engine. Never drive through water that is
slightly lower than the underbody of your vehicle. If
you cannot avoid deep puddles or standing water,
drive through them very slowly.

Brakes
Brake Fluid
Your brake master cylinder
reservoir is filled with
DOT-4 brake fluid. See
Engine Compartment
Overview on page 5-12for
the location of the
reservoir.
There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the
brake fluid goes down to an acceptable level during
normal brake lining wear. When new linings are put in,
the fluid level goes back up. The other reason is
that fluid is leaking out of the brake system. If it is, you
should have your brake system fixed, since a leak
means that sooner or later your brakes will not work
well, or will not work at all.So, it is not a good idea to top off your brake fluid.
Adding brake fluid will not correct a leak. If you add fluid
when your linings are worn, then you will have too
much fluid when you get new brake linings. You should
add or remove brake fluid, as necessary, only when
work is done on the brake hydraulic system.
{CAUTION:
If you have too much brake uid, it can spill on
the engine. The uid will burn if the engine is
hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
uid only when work is done on the brake
hydraulic system. See “Checking Brake Fluid”
in this section.
When your brake fluid falls to a low level, your brake
warning light will come on. SeeBrake System Warning
Light on page 3-27.
