Traction Control System (TCS)
Warning Light
If the TC (traction control)
warning light comes on
and stays on, there may be
a problem with the
traction control system.
The TC (traction control) warning light will come on
briefly when you turn the ignition to RUN. If it does not
come on then, have it fixed so it will be ready to
warn you if there is a problem.
If the Traction Control System (TCS) is on and you drive
faster than 100 mph (161 km/h), the system will turn
off and the TC warning light will come on. The TCS will
turn back on and the TC warning light will go out
once the vehicle speed falls below 90 mph (145 km/h).
If the TC (traction control) warning light stays on or
comes on while you are driving, pull off the road as soon
as possible and stop carefully. Try resetting the
system by turning the ignition off then back on. If the
light still stays on or comes back on again while you are
driving, your vehicle needs service. Have the traction
control system inspected as soon as possible.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. If the
gage pointer is near 260 °F (125 °C), 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 5-27for
more information.

Reduced Engine Power Light
This light is displayed
when a noticeable
reduction in the vehicle’s
performance may occur.
The vehicle may be driven at a reduced speed when
the reduced engine power light is on but acceleration
and speed may be reduced. The performance may
be reduced until the next time you drive your vehicle. If
this light stays on, see your dealer as soon as
possible for diagnosis and repair.
This light may also come on if there is a problem
with the Throttle Actuator Control (TAC) system.
If this happens, take the vehicle in for service as
soon as possible.
Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
Check Gages Warning Light
The Check Gages light will
come on briefly when you
are starting the engine.
If the light comes on and stays on while you are driving,
check your coolant temperature and engine oil
pressure gages to see if they are in the warning zones.
SeeEngine Coolant Temperature Gage on page 3-32
andOil Pressure Gage on page 3-36.
When the fuel level is low in your vehicle, the check
gages light will come on and a chime will sound. You will
also see a FUEL LEVEL LOW message on the DIC.
SeeDIC Warnings and Messages on page 3-45
for more information.

Depress Brake
This message will be displayed on the DIC when you try
to raise or lower the convertible top without first
pressing the brake pedal. The brake pedal must be
pressed in order to operate the convertible top.
SeeConvertible Top on page 2-45for more information.
Pressing the brake pedal will clear the message, or
you can press the select button to acknowledge
and clear the message from the DIC display.
Driver Door Ajar
This message will be displayed on the DIC and a chime
will sound when the driver’s door is not closed
completely. Stop the vehicle, check the door for
obstacles, and close the door again. Fully closing the
driver’s door will clear this message from the display, or
you can press the select button to acknowledge the
message and clear it from the DIC display.
Engine Coolant Hot Idle Engine
Notice:If your engine catches re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not be
covered by your warranty.
If the cooling system temperature becomes too hot, this
message will appear in the DIC and you will hear a
chime. Stop the vehicle and let the engine idle inPARK (P) to allow the coolant to reach a safe
temperature. You may need to add more coolant to your
vehicle before driving again. SeeEngine Coolant on
page 5-24andEngine Coolant Temperature Gage
on page 3-32for more information. This message will
clear from the DIC display when the coolant temperature
drops to a safe operating temperature.
Engine Overheated Stop Engine
Notice:If your engine catches re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not be
covered by your warranty.
If your engine is overheated, this message will be
displayed on the DIC. Stop the vehicle as soon as
possible and do not drive it until the engine cools down.
You may need to add more coolant to your vehicle
before driving again. SeeEngine Overheating on
page 5-27andEngine Coolant Temperature Gage on
page 3-32for more information. This message will clear
from the DIC display when the coolant temperature
drops to a safe operating temperature.
Flip Hall Switch Fault
This message will be displayed on the DIC when trying
to raise or lower the convertible top and there is a
fault with this switch. If the message persists, see your
GM dealer for service.

Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
If you have an automatic transmission, you can tow in
DRIVE (D). You may want to shift the transmission
to THIRD (3) or, if necessary, a lower gear if the
transmission shifts too often under heavy loads or hilly
conditions. If you have a manual transmission and
you are towing a trailer, it is better not to use SIXTH (6)
gear. Just drive in FIFTH (5) gear (or, as you need
to, a lower gear).
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If you turn your
engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating. To avoid this, let the
engine run while parked, preferably on level ground, with
the automatic transmission in PARK (P) for a few
minutes before turning the engine off. For manual
transmissions, let the engine run while parked,
preferably on level ground, with the transmission out of
gear and the parking brake applied, for a few minutes
before turning the engine off. If you do get the overheat
warning, seeEngine Overheating on page 5-27.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet for an automatic transmission, or
into gear for a manual transmission. Turn your
wheels into the curb if facing downhill or into traffic
if facing uphill.
2. Have someone place chocks under the
trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Release the regular brakes.
