FCA may occasionally provide an unnecessary warning
to guard rails, signs, and other stationary objects.
This is normal operation, your vehicle does not need
service.
Other Messages
There are three messages that may appear on the
Driver Information Center (DIC). They are CLEAN
RADAR, RADAR CRUISE NOT READY and SERVICE
RADAR CRUISE. SeeDIC Warnings and Messages
on page 3-79.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean the
lens. See “Cleaning the System” underAdaptive
Cruise Control on page 3-19.
Flash-to-Pass
This feature allows you to use the high-beam
headlamps to signal the driver in front of you that you
want to pass.
Pull and hold the turn signal/multifunction lever toward
you to use this feature. When you do, the following
will occur:
If the headlamps are off, in low-beam or in Daytime
Running Lamps (DRL) mode, the high-beam
headlamps will turn on. They’ll stay on as long as
you hold the lever there. Release the lever to
turn them off.
If the headlamps are in high-beam mode, they will
switch to low beam. To return to high-beam, push
the lever away from you.

Recirculation is not available in the defrost mode and
will shut off when defog mode is selected. Both of these
features are designed to limit fogging in your vehicle.
If recirculation is selected during defog mode, it will
automatically turn off after 10 minutes to limit problems
with fogging.
In some conditions, using recirculation for long periods
of time may cause the air inside your vehicle to become
too dry or stuffy. To prevent this from happening, after
the air in your vehicle has cooled, select AUTO to return
to automatic climate control operation or push the
recirculation button again to select outside air.
Pressing this button a second time selects outside air.
:(Outside Air):This mode forces the system to
pull air from outside the vehicle. It can be used to bring
fresh air into the vehicle.
Air Quality Sensor:Your vehicle may be equipped
with an optional air quality sensor to help limit the
climate control system from pulling in some harmful
exhaust fumes from older, poorly running or
diesel-equipped vehicles that are driving near you.This sensor, when active, will monitor the air quality in
front of your vehicle and switch to air recirculation when
poor quality air is detected outside your vehicle. You
can activate the air quality sensor on your vehicle
(if equipped) by pressing the AUTO button on your
climate control. The word AUTO will be shown in the
center of the climate control display under the outline
shape of a vehicle. When the air quality sensor senses
poor quality air, the recirculation graphic will be shown as
long as the sensor senses poor quality air.
Under some conditions, the air quality sensor system will
not operate. In cold weather, the system may not be
active (even if the AUTO indication is displayed) because
of concerns of fogging your windows, which may occur by
activating recirculation mode. Also, the air quality sensor
system will not remain in recirculation mode for extended
periods of time that could cause stuffy or very dry
conditions in the vehicle. Following a poorly running
vehicle for an extended period of time may not keep
recirculation active inde nitely.

Traction Control System (TCS)
Warning Light
If the TC (traction control)
warning light comes on
and stays on, there may be
a problem with the
traction control system.
The TC (traction control) warning light will come on
brie y when you turn the engine on. If it does not come
on then, have it xed so it will be ready to warn you
if there is a problem.
The light will also come on if you turn the traction
control system off using the TC (traction control) on/off
button located on the console.
If the TC (traction control) warning light stays on or comes
on while you are driving, pull off the road as soon as
possible and stop carefully. Turn your engine off and then
restart it. If the light still stays on or comes back on again
while you are driving, your vehicle needs service. Have
the traction control system inspected as soon as possible.

Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning light
will come on when the
engine is very hot.
This light will also come on brie y when the vehicle
is started.
If the light does not go out or comes on and stays on
while driving, there may be a problem with the cooling
system. Driving with engine coolant temperature light on
could cause your vehicle to overheat, seeOverheated
Engine Protection Operating Mode on page 5-31.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the Check
Engine light is on or not working properly.
To perform a Check Engine light bulb check with the
keyless ignition, make sure the transmitter fob is in the
passenger compartment. SeeIgnition Positions on
page 2-24. Press the bottom of the ACC button on
the instrument panel and hold the button down for
ve seconds. The instrument panel, including the Check
Engine light, will light up and the ignition will be on, but
the engine will not start — if you press the bottom of the
ACC button only brie y, less than ve seconds, the
accessory power mode will be turned on, but not the
ignition. After the bulb check, be sure to press and
release the ACC button again to turn the ignition off
and avoid draining the vehicle’s battery.
Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system.The vehicle would be considered not ready for inspection.
This can happen if you have recently replaced your
battery or if your battery has run down. The diagnostic
system is designed to evaluate critical emission control
systems during normal driving. This may take several
days of routine driving. If you have done this and your
vehicle still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
Oil Pressure Light
{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.
