2004 CADILLAC CTS warning light

Check Engine Oil Pressure Message
When you see this ashing
symbol, the engine oil
pressure is low.
To acknowledge this warning, press either button on the
outboard switch on the left spoke of the steering
wheel. After you press this button, the warning will
redisplay every 10 minutes until the pressure returns to
the normal operating range. Oil pressure should be
20 to 80 psi (140 to 550 kPa). In certain situations such
as long, extended idles on hot days, it could read as
low as 6 psi (40 kPa) and still be considered normal.
It may vary with engine speed, outside temperature and
oil viscosity. This warning should correspond with the
Oil Pressure Light. SeeOil Pressure Light on page 3-49
for more information.
Oil Temperature Warning Message
When you see this ashing
symbol, the engine oil
temperature is high.
To acknowledge this warning press either button on the
outboard switch on the left spoke of the steering
wheel. After you press a button, the warning will
redisplay every 10 minutes until the temperature returns
to the normal operating range. Driving aggressively
or driving on long hills can cause the engine oil
temperature to be higher than normal. If this warning is
displayed during normal vehicle operation on at
roads, your vehicle may need service. See your
GM dealer for an inspection. SeeEngine Oil on
page 5-18for more information.

Tire Pressure Warning Message
When you see this ashing
symbol, one or more of the
vehicle’s tires is either
under or over-inated.
To acknowledge this warning, press either button on the
outboard switch on the left spoke of the steering
wheel. There are three levels of warning for this display:
1. High Tire Pressure (above 42 psi (290 kPa))
2. Low Tire Pressure (below 25 psi (170 kPa))
3. Flat Tire (below 5 psi (35 kPa))For conditions 1 and 2, this warning will ash ve times
and the display will then show the tire pressure gage.
For condition 3, this warning will ash continuously until
the driver acknowledges it. In any of the three cases,
the warning will redisplay every 10 minutes until
the situation is corrected. Conditions 2 and 3 will also
display a warning light elsewhere on the cluster that will
stay illuminated after this warning is acknowledged.

Braking
Braking action involvesperception timeand
reaction time.
First, you have to decide to push on the brake pedal.
That isperception time.Then you have to bring up your
foot and do it. That isreaction time.
Averagereaction timeis about 3/4 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 3/4 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 (wet, dry, icy); tire
tread; the condition of your brakes; the weight of
the vehicle and the amount of brake force applied.
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 pacewith 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 3-44.
4-6

Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may hear
the anti-lock pump or motor operate, and feel the
brake pedal pulsate, but this is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Traction Control
System (TCS) (CTS)
Your vehicle has a traction control system that limits
wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that one or both of the rear wheels are spinning or
beginning to lose traction. When this happens,
the system brakes the spinning wheel(s) and/or reduces
engine power to limit wheel spin.
You may feel or hear the system working, but this
is normal.This warning light will
come on to let you know
if there’s a problem
with your traction
control system.
SeeTraction Control System (TCS) Warning Light on
page 3-45. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes
on whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to. You
should turn the system off if your vehicle ever gets stuck
in sand, mud or snow and rocking the vehicle is
required. See alsoWinter Driving on page 4-27for
information on using TCS when driving in snowy or
icy conditions.
