Up-Shift Light
(Manual Transmission)
This light appears
when you need to
shift to the next higher
gear on a manual
transmission vehicle.
Shifting when the indicator light is on will help you
get the best fuel economy. See “Up-Shift Light”
underManual Transmission Operation on
page 126for more information.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the
other part can still work and stop you. For good
braking, though, you need both parts working well.
If the warning light comes on, there could be a
brake problem. Have your brake system inspected
right away.
This light should come on briey when you turn
the ignition key to ON. If it does not come on then,
have it xed so it will be ready to warn you if
there is a problem.

When the ignition is on, the brake system warning
light will also come on when you set your parking
brake. SeeParking Brake on page 133for more
information. The light will stay on if your parking
brake does not release fully. If it stays on after your
parking brake is fully released, it means you have a
brake problem.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice that the
pedal is harder to push, or the pedal may go closer
to the oor. It may take longer to stop. If the light
is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 299.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System
Warning Light
With the Anti-Lock Brake
System (ABS), this light
will come on briey when
you start your engine
to show it is working.
Then it will turn off.
This is normal.
If the light stays on, or comes on when you are
driving, your vehicle needs service. If the regular
brake system warning light is not on, you still
have brakes, but you do not have anti-lock brakes.
If the regular brake system warning light is also
on, you do not have anti-lock brakes and there is
a problem with your regular brakes. SeeBrake
System Warning Light on page 189.
The ABS warning light should come on briey
when you turn the ignition key to ON. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.

Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
If the gage pointer is near the top of the gage,
the engine is too hot. It means that your engine
coolant has overheated. If you have been
operating your vehicle under normal driving
conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon
as possible.
SeeEngine Overheating on page 348for
more information.
Tire Pressure Light
This light should come
on briey when you turn
the ignition to ON.
This light will also come on when one or more
of your tires are signicantly underinated.
A LOW TIRE message will also appear in the
Driver Information Center (DIC), seeDIC Warnings
and Messages on page 202for more information.
Stop and check your tires as soon as it is safe to do
so. If underinated, inate to the proper pressure.
SeeTires on page 377for more information.
This light will ash for 60 seconds and then turn on
solid if a problem is detected with the Tire Pressure
Monitor system. SeeTire Pressure Monitor System
on page 385for more information.

Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others could
be burned. Check your oil as soon as
possible and have your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.The light will come on
when you turn your
key to ON or START.
It goes off once you start your engine. That is
a check to be sure the light works. If it does not
come on, be sure to have it xed so it will be
there to warn you if something goes wrong.
When the light comes on and stays on, it means
that oil is not owing through the engine properly.
The vehicle could be low on oil and it might
have some other system problem. SeeEngine
Oil on page 333and “OIL” underDIC Warnings
and Messages on page 202for more information.

Daytime Running Lamps (DRL)
Indicator Light
This light turns
on whenever the
Daytime Running
Lamps are on.
SeeDaytime Running Lamps (DRL) on page 171
for more information.
Fuel Gage
When the ignition
is on, the fuel gage
tells you about
how much fuel you
have remaining in
the fuel tank.Here are four things that some owners ask
about. None of these indicate a problem with
your fuel gage:
At the gas station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the gage indicated. For example, the gage
may have indicated the tank was half full,
but it actually took a little more or less than
half the tank’s capacity to ll the tank.
The gage moves a little when you turn a
corner or speed up.
The gage does not go back to empty when
you turn off the ignition.
When the fuel in the fuel tank is low, you will see
a LOW FUEL message on the Driver Information
Center (DIC) display. SeeDIC Warnings and
Messages on page 202for more information.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the
driver that the status of the vehicle has changed
and that some action may be needed by the driver
to correct the condition. Multiple messages may

Control of a Vehicle
You have three systems that make your vehicle go
where you want it to go. They are the brakes, the
steering, and the accelerator. All three systems
have to do their work at the places where the tires
meet the road.
Sometimes, as when you are driving on snow
or ice, it is easy to ask more of those control
systems than the tires and road can provide.
That means you can lose control of your vehicle.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 324.
Braking
SeeBrake System Warning Light on page 189.
Braking action involves perception time and
reaction time.First, you have to decide to push on the brake
pedal. That is perception time. Then you have to
bring up your foot and do it. That is reaction time.
Average reaction time is about three-fourths of
a second. But that is only an average. It might
be less with one driver and as long as two or
three seconds or more with another. Age, physical
condition, alertness, coordination, and eyesight
all play a part. So do alcohol, drugs, and
frustration. But even in three-fourths of a second,
a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in
an emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary
greatly with the surface of the road, whether it
is pavement or gravel; the condition of the road,
whether it is wet, dry, or icy; tire tread; the
condition of the brakes; the weight of the vehicle;
and the amount of brake force applied.
