outside. During that delay, the
instrument panel cluster may not be
as bright as usual. Make sure the
instrument panel brightness knob
is in the full bright position. See
Instrument Panel Illumination
Control on page 6‑6for more
information.
If it is dark enough outside and
the exterior lamp control is off,
a HEADLAMPS SUGGESTED
message will display on the Driver
Information Center (DIC). See Lamp
Messages on page 5‑43.
Turning the exterior lamp control
to off a second time, or turning on
the headlamps will remove the
HEADLAMPS SUGGESTED
message in the DIC. If the parking
lamps or the fog lamps were turned
on instead, the HEADLAMPS
SUGGESTED message will
continue to be displayed.
The regular headlamp system
should be turned on when needed. To turn off the DRL, turn the exterior
lamp control to the off position or
shift into P (Park). The DRL will
stay off until the control is toggled
again or the vehicle is shifted out
of P (Park).
This procedure applies only to
vehicles first sold in the United
States.
Twilight Sentinel
Twilight Sentinel®is an automatic
headlamp system. When activated,
this feature turns your headlamps
and parking lamps on and off by
sensing how dark it is outside.
Be sure not to cover the light sensor
on the top of the instrument panel. AUTO:
Activates the system.
If the band is already in the AUTO
position when you start your vehicle,
Twilight Sentinel is automatically
enabled.
If it is dark outside, your vehicle
headlamps and parking lamps will
turn on automatically.
Once it is bright enough outside,
the headlamps and parking lamps
will automatically turn back off.
Twilight Sentinel may also turn on
when you drive through a dimly
lit area.
Once you leave the dimly lit area, it
may take about one minute before
the Twilight Sentinel turns off.
During this brief delay, the
instrument cluster may not be as
bright as usual. Make sure the
instrument panel dimmer is set to
full brightness. See Instrument
Panel Illumination Control on
page 6‑6.

8-2 Climate Controls
When the vehicle is first started,
the display shows the driver's
temperature setting, the outside
temperature, the fan speed, and the
air delivery, for about 10 seconds.
The outside temperature is shown
in the center of the display.
The digital display will show the
readings in Fahrenheit or Celsius.
See“Personal Options” under
Vehicle Personalization on
page 5‑54 for information on
changing your display.
Automatic Operation
AUTO (Automatic): Press the
AUTO button to place the entire
system in the automatic mode.
When automatic operation is active,
the system automatically controls
the inside temperature, the air
delivery mode, and the fan speed. After a 10 second display of the
current settings, the word AUTO,
the driver's temperature setting and
the outside temperature will be
shown. The system operates to
reach the 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.
1. Press the AUTO button.
2. Adjust the temperature to a
comfortable setting between
16°C (60°F) and 32°C (90°F).
Choosing the coldest or warmest
temperature setting will not
cause the system to heat or cool
any faster. A setting of 23°C
(73°F) is suggested.
In cold weather, the system will
start at reduced fan speeds to
avoid blowing cold air into
your vehicle until warmer air is available. The system starts out
blowing air at the floor but may
change modes automatically as
the vehicle warms up to maintain
the chosen temperature setting.
The length of time needed for
warm up depends on the outside
temperature and the length of
time that has elapsed since the
vehicle was last driven.
3. Wait for the system to regulate. This may take from 10 to
30 minutes. Then adjust the
temperature, if necessary.
Do not cover the solar sensor
located in the center of the
instrument panel, near the
windshield. For more information
on the solar sensor, see “Sensors”
later in this section.

from happening, after the air in
the vehicle has cooled, turn the
recirculation mode off.
The air conditioning system
removes moisture from the air, so a
small amount of water might drip
under the vehicle while idling or
after turning off the engine. This is
normal.
?(Recirculation):Press to turn
the recirculation mode on or off.
An indicator light comes on to show
that recirculation is on. This mode
prevents outside air from entering
your vehicle. It can be used to
prevent outside air and odors from
entering your vehicle and to help
cool the air inside your vehicle more
quickly. Recirculation mode is not
available in defrost or defog mode.
Sensors
The solar sensor on the vehicle
monitors the solar heat and uses
the information to maintain the
selected temperature when
operating in AUTO mode by
automatically adjusting the
temperature, fan speed, and air
delivery system. The system may
also supply cooler air to the side
of the vehicle facing the sun.
The recirculation mode will also be
activated, as necessary. Do not
cover the solar sensor located on
the top of the instrument panel near
the windshield or the system will not
work properly.
There is also a sensor located
behind the front bumper. This
sensor reads the outside air
temperature and helps to maintain
the temperature inside the vehicle.
Any cover on the front of the vehicle
could give a false reading in the
temperature. If the outside temperature goes up,
the displayed temperature will not
change until:
.The vehicle's speed is above
19 km/h (12 mph) for
five minutes.
.The vehicle's speed is above
52 km/h (32 mph) for two and
one‐half minutes.
These delays prevent false
readings. If the temperature goes
down, the outside temperature
will be shown when you start the
vehicle. If it has been turned off
for less than three hours, the
temperature will be recalled from the
previous vehicle operation.
There is also an inside temperature
sensor located to the left of the
ignition switch. The automatic
climate control system uses this
sensor to receive information, so if
you block or cover it, the system will
not function properly.

10-36 Vehicle Care
The ZR1, Z06, and Grand Sport
models also have an electronic
brake pad wear sensor system.
When pads are worn, the CHANGE
BRAKE PADS message displays
in the Driver Information Center.
SeeBrake System Messages on
page 5‑36. Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Brake linings should always be
replaced as complete axle sets.
Brake Rotor Wear
ZR1 models have, and Z06 and
Grand Sport models may have,
ceramic brake rotors. Rotors should
be visually inspected whenever the
brake pads are replaced. Rotors
also need to be weighed before
brake pads are replaced to confirm
that the rotor mass is greater than
the wear‐out mass printed on the
rotor. The rotor can be reused if the
weight of the rotor is above the
mass limit. Rotor inspection and
weighing methods can be found in
the service manual. See
Service
Publications Ordering Information
on page 13‑18. Brake Rotor Protector
{WARNING
Ceramic rotors will be very hot
after operation and touching them
may cause burns. Be sure brake
system is completely cool prior to
installation of protector, or coming
in contact with them.
Notice: Rotors may be chipped
if hard contact is made with the
wheel during wheel installation or
removal. Always use the rotor
protectors. Be sure to carefully
follow wheel removal and
installation instructions.
