Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be careful
not to reset the OIL LIFE accidentally at any time other
than when the oil has just been changed. It can't be reset
accurately until the next oil change.
To reset the system, see ªHow to Reset the Change Oil
Soon Messageº in the Index.
Also, see ªEngine Oil, When to Changeº and
ªMaintenance Scheduleº in the Index.

LOW OIL PRESSURE: You will hear four chimes and
the CHECK GAGES telltale will come on when this
message is displayed. To acknowledge the warning,
press the RESET button. After you press the RESET
button, a message will be displayed and you will hear a
chime every minute until the vehicle is serviced. If you
do not press RESET, the message will remain on the

Low oil pressure may be the result of a combination of
low oil level and abrupt changes in the vehicle's
direction. When this warning is displayed, you should
not operate the engine at high rpm or make fast abrupt
moves. As soon as possible, you should check the oil
level. See ªEngine Oilº in the Index.
LOW OIL LEVEL: Press RESET to acknowledge that

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

used 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 hear two chimes when this message is
displayed. To acknowledge the warning, press RESET.
After you press RESET, a message will appear 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),

Mobility Tiresº and ªTire Pressure Monitorº 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.

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

HIGH TIRE PRESSURE - (LF, LR, RF, RR)
(Except Z06): You will hear two chimes when this
message is displayed. To acknowledge the warning,
press RESET. After you press RESET, a message will
reappear 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

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 have been sent at the same time, press RESET.
If a tire pressure message appears on the DIC, stop as

See ªExtended Mobility Tiresº and ªTire Inflationº in
the Index.SERVICE TIRE MON SYS (Except Z06): If this
message comes on, 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

3-4 Automatic Electronic Dual Climate
Control System (Option)
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 set temperature will be
remembered each time you turn the ignition off and
restart in the same settings. You can use the memory
option to 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 unless you
are in full cold 60
F (16
C) or full hot 90
F (32
C),
then the word AUTO will not 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.

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 unless
you are in full cold 60
F (16
C) or full hot 90
F
(32
C), then the word AUTO will not display. The
system will operate to achieve your comfort set
temperature as quickly as possible. 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.
