If the Driver Information Center (DIC) displays the
REDUCED ENGINE POWER message and the
CHECK ENGINE light comes on, a noticeable
reduction in the vehicle's performance may occur. If the
REDUCED ENGINE POWER message is displayed but
there is no reduction in performance, proceed to your
destination. The performance may be reduced the next
time the vehicle is driven.
The vehicle may be driven at a reduced speed while the
REDUCED ENGINE POWER message is displayed,
but acceleration and speed may be reduced. Anytime the
CHECK ENGINE light stays on, the vehicle should be
taken to an authorized Chevrolet dealer as soon as
possible for diagnosis and repair.
Also, refer to ªMalfunction Indicator Lampº (Check
Engine Light) in the Index. If the REDUCED ENGINE
POWER message is displayed in combination with the
COOLANT OVER TEMP message, see ªEngine
Overheatingº in the Index.

to indicate to the driver that the Selective Real Time
Damping (SRTD) system has detected a malfunction
and that the system must be serviced. The SERVICE
RIDE CONTROL message will always come on when a
failure is detected by the Selective Real Time Damping
(SRTD) system. If a fault is present in the SRTD
which causes the shocks to be in their full soft condition,
the SERVICE RIDE CONTROL, SHOCKS
INOPERATIVE and MAXIMUM 80 MPH (129 km/h)
will display together. You will never get a SHOCKS
INOPERATIVE and MAXIMUM SPEED 80 MPH
(129 km/h) message without a SERVICE RIDE
CONTROL message.
SHOCKS INOPERATIVE: You will hear four chimes
when this message is displayed. To acknowledge that
you have read the message and to remove it from the
display, press RESET. The message will reappear every
10 minutes until this condition changes.
This message indicates that a malfunction is present in

LOW TIRE PRESSURE: You will hear two chimes
when this message is displayed. To acknowledge the
warning, press RESET. After you press RESET, a
message will reappear and you will hear a chime every
10 minutes until this condition changes. This message
indicates that the pressure in one of your tires is less
than 25 psi (172 kPa). Next to the LOW TIRE
PRESSURE message, you can see either LF (left front),
LR (left rear), RF (right front) or RR (right rear) to
indicate to you which tire is low on pressure. 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 RESET. 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 your
Tire Loading Information Label. See ªExtended
Mobility Tiresº in the Index.
CAUTION:
When the LOW TIRE PRESSURE or FLAT
TIRE message is displayed on the Driver
Information Center, 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. Don't drive over 55 mph (90 km/h) when
the LOW TIRE PRESSURE or FLAT TIRE
message is displayed. Drive cautiously, and check
your tire pressures as soon as you can.

your driving accordingly. To acknowledge these
warnings, press RESET. After you press RESET, a
message will reappear and you will hear a chime every
10 minutes until this condition changes. This message
indicates that the pressure in one of your tires is lower
than 5 psi (34 kPa). Next to the FLAT TIRE message,
you can see either LF (left front), LR (left rear), RF
(right front) or RR (right rear) to indicate to you which
tire is flat. 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 RESET. 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 your Tire Loading Information Label. See
ªExtended Mobility Tiresº and ªTire Inflationº in

HIGH TIRE PRESSURE - (LF, LR, RF, RR): Yo u
will hear two chimes when this message is displayed. To
acknowledge the warning, press RESET. After you press
RESET, a message will reappear and you will hear a
chime every 10 minutes until this condition changes.
This message indicates that the pressure in one of your
tires is higher than 42 psi (290 kPa). Next to the HIGH
TIRE PRESSURE message, you can see either LF
(left front), LR (left rear), RF (right front) or RR (right
rear) to indicate to you which tire is higher than 42 psi
(290 kPa). You can receive more than one tire pressure
message at a time. To read other messages that may

a part on the Tire Pressure Monitor (TPM) 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 approximately 10 minutes. If all four
sensors are missing, the warning will come on in
approximately 15 to 20 minutes. (All the sensors 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.

3-4 Automatic Electronic Dual Climate Control
System (If Equipped)
Your vehicle may be equipped with an Automatic
Electronic Dual Climate Control System. This system
can automatically adjust and control temperature output,
fan speed, air delivery mode, air conditioning operation
and air intake. You can use the AUTO (automatic)
setting or override the automatic operation with
manual control settings. The control settings will be
remembered each time you turn the ignition off
and restart in the same settings. You can use the
memory option to store and recall your settings.
(See ªMemoryº in the Index.)Digital Display
The digital display shows readings in Fahrenheit or
Celsius by pressing the E/M button (English/Metric) on
the Driver Information Center (DIC). When you start
the vehicle, the display will show the current fan speed,
air delivery mode and the driver
-set temperature for
approximately five seconds and then show the
outside temperature.
When the system is fully in the automatic mode, the
word AUTO will also appear on the display. If you have
selected a manual fan speed, then the fan symbol will
appear on the display. If a manual air delivery mode has
been selected, the delivery mode symbol will appear on
the display.
Driver Set Temperature Knob
The DRIVER knob changes the temperature on the
driver's and passenger's side of the vehicle. Turn the
knob clockwise to increase the temperature and
counterclockwise to decrease the temperature.
Whenever you turn this knob, the temperature will be
displayed for approximately five seconds along with the
current fan speed and air delivery mode.

yellowblue
3-5
When adjusting the temperature, start with a driver-set
temperature of 73
F (23
C) until you determine your
comfort zone. If you choose 60
F (16
C), the
system will remain at maximum cooling and will not
automatically adjust fan speed or air delivery. If you
choose 90
F (32
C), the system will remain at
maximum heating and will not automatically adjust fan
speed or air delivery. Choosing either maximum setting
will not cause the system to heat or cool any faster.
Turning the knob past either maximum setting has no
effect on the operation of the system.
Passenger Temperature Offset
The PASSENGER knob changes the temperature on the
passenger's side of the vehicle. When the knob is in the
12 o'clock position, the passenger's temperature is the
same as the driver's. Turn the knob clockwise for
warmer air on the passenger's side, counterclockwise for
cooler air. If the driver
-set temperature is set at 60
F
(16
C) or 90
F (32
C), turning the passenger knob
has no effect because the system is locked at a
maximum setting.Automatic Operation
Press the AUTO button to place the entire system in the
automatic mode. After a five
-second display of the
current settings, only the word AUTO and the outside
temperature will be shown on the digital display. The
system will operate to achieve your comfort set
temperature as quickly as possible. If you have set the
driver temperature at 60
F (16
C) or 90
F (32
C),
the system will not operate automatically until a
different temperature is selected. The AUTO control
system works best with the windows up and the
removable roof installed or the convertible top up.
A Typical Cold Weather Example:
Your vehicle has been parked outside overnight in cold
weather (below 32
F/ 0
C) and you have set the driver
temperature at 73
F (23
C) and have selected the
AUTO mode. The system will automatically adjust the
temperature output to maximum heating. The fan will
start at a low speed. This is to avoid blowing cold air
into the vehicle. The length of the delay depends on the
amount of time since the engine was last started, the
outside temperature and the engine coolant temperature.
As the coolant warms up, the fan speed will gradually
increase. Air will flow to the floor with some air to
the windshield to prevent fogging under most
normal conditions.
