Multiple chimes sound when this message is displayed.
This message remains displayed and active until the
issue is resolved.
HEADLAMPS SUGGESTED
This message displays if it is dark enough outside and
the headlamps and the Twilight Sentinel®controls
are off. This message informs the driver that turning on
the exterior lamps is recommended. It has become
dark enough outside to require the headlamps and/or
other exterior lamps.
HIGH TIRE PRESSURE
This message displays when one or more of the tires is
over-inated. This message also displays LEFT FRONT,
RIGHT FRONT, LEFT REAR, or RIGHT REAR to
indicate which tire is affected. You can receive more
than one tire pressure message at a time. To read other
messages that may have been sent at the same time,
press the RESET button. If a tire pressure message
appears on the DIC, stop as soon as you can. Have the
tire pressures checked and set to those shown on the
Tire Loading Information label. SeeRun-Flat Tires
on page 5-69,Loading the Vehicle on page 4-22,
Inflation - Tire Pressure on page 5-70, andTire Pressure
Monitor System on page 5-73. The DIC also shows
the tire pressure values. SeeDIC Operation and
Displays on page 3-49.To acknowledge the message, press the RESET button.
A message reappears every 10 minutes until the
condition is corrected.
HOT ENGINE AIR CONDITIONING OFF
This message displays when the engine coolant
becomes hotter than the normal operating temperature.
To avoid added strain on a hot engine, the air
conditioning compressor is automatically turned off.
When the coolant temperature returns to normal, the A/C
operation automatically resumes. You can continue to
drive the vehicle. If this message continues to appear,
have the system repaired by your dealer/retailer as soon
as possible to avoid compressor damage.
ICE POSSIBLE
This message displays when the outside air temperature
is cold enough to create icy road conditions. Adjust your
driving accordingly.
LOW FUEL
This message displays when the fuel tank is less than
10 percent full and the display is turned off. A sound will
be heard when this message is displayed. Rell the
fuel tank as soon as possible. SeeFuel Gage on
page 3-48.

LOW OIL PRESSURE
This message displays if low oil pressure levels occur.
If this message appears while the engine is running,
stop the engine and do not operate it until the cause of
low oil pressure is corrected. Severe damage to the
engine can result. A sound will be heard when this
message is displayed. SeeEngine Oil on page 5-20.
LOW TIRE PRESSURE
{CAUTION:
When the LOW TIRE PRESSURE or TIRE FLAT
message is displayed on the Driver Information
Center, your vehicle’s handling capabilities will be
reduced during severe maneuvers. The active
handling system will be affected. SeeActive
Handling System on page 4-8. If you drive too
fast, you could lose control of your vehicle. You or
others could be injured. Do not drive over 55 mph
(90 km/h) when the LOW TIRE PRESSURE or
TIRE FLAT message is displayed. Drive cautiously
and check your tire pressures as soon as you can.This message displays when one or more of the tires is
under-inated. This message also displays LEFT
FRONT, RIGHT FRONT, LEFT REAR, or RIGHT REAR
to indicate which tire is affected. Multiple chimes sound
and the tire pressure light on the instrument panel cluster
turns on when this message is displayed. SeeTire
Pressure Light on page 3-42. You can receive more than
one tire pressure message at a time. To read other
messages that may have been sent at the same time,
press the RESET button. If a tire pressure message
appears on the DIC, stop as soon as you can. Have the
tire pressures checked and set to those shown on the
Tire Loading Information label. SeeRun-Flat Tires
on page 5-69,Loading the Vehicle on page 4-22,
Inflation - Tire Pressure on page 5-70, andTire Pressure
Monitor System on page 5-73. The DIC also shows the
tire pressure values. SeeDIC Operation and Displays
on page 3-49.
To acknowledge the message, press the RESET button.
A message reappears every 10 minutes until the
condition is corrected.
MAXIMUM SPEED 80 MPH (129 km/h)

This message is followed by the MAXIMUM SPEED
55 MPH (90 km/h) message, and then by the REDUCED
HANDLING message. The Active Handling System
will intervene more quickly when a at tire has been
detected. Adjust your driving accordingly.
You can receive more than one tire pressure message
at a time. To read other messages that may have
been sent at the same time, press the RESET button.
If a tire pressure message appears on the DIC, stop as
soon as you can. Have the tire pressures checked
and set to those shown on the Tire Loading Information
label. SeeRun-Flat Tires on page 5-69,Loading the

Run-Flat Tires
This vehicle, when new, had run-at tires. There is no
spare tire, no tire changing equipment, and no place
to store a tire in the vehicle. Run-at tires perform
so well without any air that a Tire Pressure Monitor
System (TPMS) is used to alert you if a tire has
lost pressure.
{CAUTION:
When the low tire warning light is displayed on
the instrument panel cluster, your vehicle’s handling
capabilities will be reduced during severe
maneuvers. If you drive too fast, you could lose
control of your vehicle. You or others could be
injured. Do not drive over 55 mph (90 km/h)
when the low tire warning light is displayed.
Drive cautiously and check your tire pressures
as soon as you can.
If a tire goes at, you will not need to stop on the side of
the road to change the tire. You can just keep on driving.
The shorter the distance you drive and the slower thespeed, the greater the chance that the tire will not have
to be replaced. If you drive on a deated run-at tire
for 25 miles (40 km) or less and at speeds of 55 mph
(90 km/h) or less, there is a good chance that the tire
can be repaired. The tires on coupe, convertible and
Z06 models can operate effectively with no air pressure
for up to 100 miles (160 km) at speeds up to 55 mph
(90 km/h), but the tire would then have to be replaced.
The tires on ZR1 models can operate effectively with no
air pressure for up to 50 miles (80 km) at speeds up to
55 mph (90 km/h), but the tire would then have to be
replaced. When a tire is lled with air, it provides a
cushion between the road and the wheel. Because you
will not have this cushion when driving on a deated tire,
try to avoid potholes that could damage your wheel and
require replacement of it.
Some road hazards can damage a tire beyond repair.
This damage could occur even before you have driven
on the tire in a deated condition. When a tire has
been damaged, or if you have driven any distance
on a run-at tire, check with an authorized run-at tire
service center to determine whether the tire can be
repaired or should be replaced. To maintain your
vehicle’s run-at feature, all replacement tires must
be self-supporting tires. As soon as possible, contact
the nearest authorized GM or run-at servicing
facility for inspection and repair or replacement.
5-69

The vehicle, when new, had run-at tires. This type of
tire can operate effectively with no air pressure, so you
will not need to stop on the side of the road to change a
at tire. You can just keep on driving. The shorter the
distance you drive and the slower the speed, the greater
the chance that the run-at tire will not have to be
replaced. Run-at tires perform so well without any air
that a Tire Pressure Monitor System (TPMS) is used to
alert you if a tire has lost pressure. SeeRun-Flat Tires
on page 5-69andTire Pressure Monitor System on
page 5-73.
{CAUTION:
Special tools and procedures are required to
service a run-at tire. If these special tools and
procedures are not used you or others could be
injured and the vehicle could be damaged. Always
be sure the proper tools and procedures, as
described in the service manual, are used.
To order a service manual, seeService Publications
Ordering Information on page 7-15.
Appearance Care
Interior Cleaning
The vehicle’s interior will continue to look its best if it
is cleaned often. Although not always visible, dust and
dirt can accumulate on the upholstery. Dirt can damage
carpet, fabric, leather, and plastic surfaces. Regular
vacuuming is recommended to remove particles from
the upholstery. It is important to keep the upholstery from
becoming and remaining heavily soiled. Soils should be
removed as quickly as possible. The vehicle’s interior
may experience extremes of heat that could cause
stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to home furnishings may also transfer
color to the vehicle’s interior.
