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.

Fuel Level Low
If the fuel level is low in the vehicle’s gas tank, this
message will appear on the DIC and you will hear a
chime. You will also see the check gages warning light
on the instrument panel cluster. SeeCheck Gages
Warning Light on page 3-38for more information. Refuel
as soon as possible. SeeFilling the Tank on page 5-8
andFuel Gage on page 3-39for more information. Press
the select button to acknowledge and clear the
message from the display.
Hdr (Header) Latch 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.
Manually Open Tonneau
This message will be displayed on the DIC when trying
to raise or lower the convertible top while the
convertible top and roof tonneau are where the system
cannot verify their position. The roof system may
need to be restored manually to a stable position by
fully opening the roof tonneau and boot cover panel. See
Convertible Top on page 2-45for more information.
Oil Pressure Low Stop Engine
{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.
If the oil pressure is low in your vehicle, this message
will be displayed on the DIC. Stop the vehicle as
soon as possible and do not drive it until the cause of
the low oil pressure has been corrected. Check your oil
as soon as possible and have your vehicle serviced
by your GM dealer. SeeEngine Oil on page 5-13andOil
Pressure Gage on page 3-36for more information.

Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
first part of the journey. Wear comfortable clothing
and shoes you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course, you
will find experienced and able service experts in GM
dealerships all across North America. They will be ready
and willing to help if you need it.
Here are some things you can check before a trip:
•Windshield Washer Fluid:Is the reservoir full? Are
all windows clean inside and outside?
•Wiper Blades:Are they in good shape?
•Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
•Lamps:Are they all working? Are the lenses clean?
•Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
•Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
•Maps:Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as highway hypnosis?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the
wind against the vehicle that can make you sleepy. Do
not let it happen to you! If it does, your vehicle can
leave the road in less than a second, and you could
crash and be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
•Make sure your vehicle is well ventilated, with a
comfortably cool interior.
•Keep your eyes moving. Scan the road ahead and
to the sides. Check your mirrors and your
instruments frequently.
•If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get some
exercise, or both. For safety, treat drowsiness
on the highway as an emergency.

BSubtract Occupant
Weight @ 200 lbs
(91kg)x2=400 lbs (181 kg)
CAvailable Cargo

Refer to your vehicle’s tire and loading information label
for specific information about your vehicle’s capacity
weight and seating positions. The combined weight of
the driver, passengers, and cargo should never
exceed your vehicle’s capacity weight.
Certi cation/Tire Label
A vehicle specific Certification/Tire label is attached to
the rear edge of the driver’s door. The label shows
the size of your original tires and the inflation pressures
needed to obtain the gross weight capacity of your
vehicle. This is called the Gross Vehicle Weight Rating
(GVWR). The GVWR includes the weight of the
vehicle, all occupants, fuel, cargo, and trailer tongue
weight, if pulling a trailer. Example 3
