2007 CADILLAC ESCALADE ESV warning light

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that
something is wrong before it becomes serious
enough to cause an expensive repair or
replacement. Paying attention to your warning
lights and gages could also save you or others
from injury.
Warning lights come on when there may be or
is a problem with one of your vehicle’s functions.
As you will see in the details on the next few
pages, some warning lights come on briey when
you start the engine just to let you know they’re
working. If you are familiar with this section,
you should not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions.
Often gages and warning lights work together to
let you know when there’s a problem with
your vehicle.
When one of the warning lights comes on and
stays on when you are driving, or when one of
the gages shows there may be a problem, check
the section that tells you what to do about it.
Please follow this manual’s advice. Waiting to do
repairs can be costly – and even dangerous.
So please get to know your warning lights and
gages. They’re a big help.
Your vehicle also has a Driver Information Center
(DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 245.

Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, but the
engine is not running,
as a check to show you
it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving,
you may have a problem with the charging system.
It could indicate that you have problems with the
generator, the generator drive belt, or another
electrical problem. Have it checked right away.
Driving while this light is on could drain your
battery.
When this light comes on, the DIC will also display
the SERVICE BATTERY NOT CHARGING
SYSTEM message. SeeDIC Warnings and
Messages on page 250for more information.If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner, to reduce
the drain on your battery.
Brake System Warning Light
With the ignition on, the brake system warning
light will come on when you set the parking brake.
If you try to drive with the parking brake engaged,
a chime will sound when the vehicle speed is
greater than 3 mph (5 km/h).
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.
235

If the warning light comes on and a chime sounds
there could be a brake problem. Have your
brake system inspected right away.
This light may also come on due to low brake
uid. SeeBrakes on page 433for more
information.
This light should come on briey when you turn
the ignition key to RUN. If it does not come
on then, have it xed so it will be ready to warn
you if there’s a 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 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 376.
{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, this light will
come on when you start
your engine and may

seconds.
That’s normal. If the light does not come on then,
have it xed so it will be ready to warn you if
there is a problem.
If the light stays on, or comes on when you are
driving, your vehicle needs service. You will also
hear a chime sound when the light is on steady. 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. In addition to
both lights, you will also hear a chime sound on the

should come on briey
when the engine is
started.
If the warning light does not come on then, have it
xed so it will be ready to warn you if there is a
problem. If it stays on, or comes on when you
are driving, there may be a problem with your
StabiliTrak
®system and your vehicle may need
service. When this warning light is on, the system is
off and will not limit wheel spin. Adjust your driving
accordingly.
This light will also ash when the StabiliTrak
®
system is active.

time when the system is turned on, your vehicle
needs service. SeeStabiliTrak
®System on
page 330for more information.
Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
If the gage pointer moves towards the shaded in
thermostat, 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 422.
Tire Pressure Light
This light will come on
briey when you turn

pressure warning light will come on. SeeTire
Pressure Light on page 238.
DRIVER DOOR OPEN
If the driver’s door is not fully closed and the
vehicle is in a drive gear, this message will display
and a chime will sound. Stop and turn off the
vehicle, check the door for obstructions, and close
the door again. Check to see if the message
still appears on the DIC.
ENGINE HOT A/C (Air Conditioning)

This message will display when the engine coolant
becomes hotter than the normal operating
temperature. SeeEngine Coolant Temperature
Gage on page 238. To avoid added strain on
a hot engine, the air conditioning compressor

(TPM) system, this message will display if a part
on the system is not working properly. If you
drive your vehicle while any of the four sensors
are missing or inoperable, the warning will
come on in about 20 minutes. A sensor would be
missing, for example, if you put different wheels
on your vehicle without transferring the sensors.
If the warning comes on and stays on, there
may be a problem with the TPM. See your dealer.

you should turn StabiliTrak®off if your vehicle gets
stuck in sand, mud, ice, or snow and you want
to rock your vehicle to attempt to free it, or if you
are driving in extreme off-road conditions and
require more wheel spin. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 368.
To turn the StabiliTrak
®system on or off, see
StabiliTrak®System on page 330.
