2009 CHEVROLET COBALT warning light

Traction Control Operation
Traction control limits wheel spin by reducing engine
power to the wheels (engine speed management)
and by applying brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is enabled automatically
when you start your vehicle, and it will activate and ash
the ESC/TCS light and display the LOW TRACTION
message if it senses that any of the wheels are spinning
or beginning to lose traction while driving. For more
information on the LOW TRACTION message,
seeDriver Information Center (DIC) on page 3-40.
Notice:If you allow the wheel(s) of one axle to spin
excessively while the ESC/TCS, ABS and Brake
warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed, you
could damage the differential. The repairs would not
be covered by your warranty. Reduce engine
power and do not spin the wheel(s) excessively
while these lights and this message are displayed.Notice:When traction control is turned off, or
Competitive Driving Mode is active, it is possible to
lose traction. If you attempt to shift with the front
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not
attempt to shift when the front wheels do not have
traction. Damage caused by misuse of the vehicle
is not covered. See your warranty book for
additional information.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens, you may notice
a reduction in acceleration, or may hear a noise or
vibration. This is normal.
If your vehicle is in cruise control while the system
activates, the ESC/TCS light ashes and the cruise
control automatically disengages. When road conditions
allow you to use cruise control again, you may
re-engage the cruise control. SeeCruise Control on
page 3-10.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.

Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if
it senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may also
upshift the transmission to limit wheel spin. You may feel
or hear the system working, but this is normal.
If your vehicle has ETS, there is not an ESC/TCS
button on the instrument panel. To turn the system off,
shift to LOW (L) or REVERSE (R). There is more
information about how to turn the system off later in
this section.
The light below ashes and a LOW TRACTION
message will appear on the Driver Information Center
(DIC) when the traction control system is actively limiting
wheel spin. You may feel or hear the system working,
but this is normal. Slippery road conditions may
exist if this message is displayed, so adjust your driving
accordingly.
If your vehicle is in cruise control when the ETS begins
to limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may re-engage the cruise control.
SeeCruise Control on page 3-10.The ETS indicator/warning light may come on for the
following reasons:
The indicator/warning light ashes while the traction
control system is limiting wheel spin.
If you turn the system off by moving the shift lever to
LOW (L), the indicator/warning light will come on and
stay on. To turn the system back on, move the shift
lever back to a position other than LOW (L). The
indicator/warning light should go off.
The indicator/warning light will come on when you set
your parking brake with the engine running, and it will
stay on if your parking brake does not release fully. If
the transmission shift lever is in any position other
than LOW (L) and the indicator/warning light stays on
after your parking brake is fully released, it means
there is a problem with the system.
If the traction control system is affected by an engine
related problem, the system will turn off and the
indicator/warning light will come on.
4-9

If the ETS indicator/warning light comes on and stays
on for an extended period of time when the transmission
shift lever is in any position other than LOW (L), your
vehicle may need service.
When this light is on solid, the system will not limit
wheel spin. Adjust your driving accordingly.
Check your DIC messaging to determine whether it is
because of the driver turning off the system, or that the
system may not be working properly and your vehicle
requires service. When this light is turned on, either the
SERVICE TRACTION or TRACTION OFF message
will be displayed.
SeeDIC Warnings and Messages on page 3-43for
more information on the messages associated with
this light.
To limit wheel spin, especially in slippery road
conditions, you should always leave the ETS on.
But you can turn the system off if you prefer.
To turn the system off, shift to LOW (L) or
REVERSE (R).
When you turn the system off, the ETS indicator/warning
light will come on and stay on and TRACTION OFF
message will be displayed when the gear shift is
in LOW (L). The indicator/warning light and message
will not come on when the gear shift is in REVERSE (R).
If the ETS is limiting wheel spin when you shift to
LOW (L) or REVERSE (R) to turn the system off, theindicator/warning light and TRACTION OFF will come
on in LOW (L). But the system won’t turn off right away.
It will wait until there’s no longer a current need to
limit wheel spin.
SeeDIC Warnings and Messages on page 3-43for
more information on the messages associated with
this light.
You can turn the system back on at any time by
shifting to AUTOMATIC OVERDRIVE (D) or
INTERMEDIATE (I). The ETS indicator/warning light
should go off.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
Electronic Stability Control (ESC)
Your vehicle may have an Electronic Stability Control
(ESC) system which combines antilock brake, and
traction and stability control systems that help the driver
maintain directional control of the vehicle in most
driving conditions.
When the vehicle is started and begins to move, the
system performs several diagnostic checks to ensure
there are no problems. You may hear or feel the system
working. This is normal and does not mean there is a
problem with your vehicle. The system should initialize
before the vehicle reaches 20 mph (32 km/h).
4-10

If the system fails to turn on or activate, the ESC/TCS
light comes on, and the ESC OFF and/or SERVICE ESC
message displays.
For more information, seeDriver Information Center
(DIC) on page 3-40andElectronic Stability Control
(ESC)/Traction Control System (TCS) Indicator/Warning
Light on page 3-33.
This light ashes on the
instrument panel cluster
when the ESC system
is on and activated.
ESC activates when the computer senses a discrepancy
between your intended path and the direction the
vehicle is actually travelling. ESC selectively applies
braking pressure at any one of the vehicle’s brakes to
help steer the vehicle in the direction which you are
steering.
When the system activates, an ESC ACTIVE
message displays on the Driver Information Center.
SeeDIC Warnings and Messages on page 3-43.This light also ashes on the instrument panel
cluster when the ESC system is on and activated.
You may also hear a noise or feel vibration in the brake
pedal. This is normal. Continue to steer the vehicle in
the direction you want it to go.
When the light is on solid and the message(s),
SERVICE ESC, ESC OFF, or both display, the system
will not assist the driver in maintaining directional
control of the vehicle. Adjust your driving accordingly.
SeeDIC Warnings and Messages on page 3-43.
The Electronic Stability Control (ESC) system is
automatically enabled whenever you start your vehicle.
To assist the driver with vehicle directional control,
especially in slippery road conditions, you should always
leave the system on. But, you can turn ESC off if you
ever need to.
If the vehicle is in cruise control when the system
begins to assist the driver maintain directional control of
the vehicle, the ESC/TCS light will ash and the
cruise control will automatically disengage. When road
conditions allow you to use cruise again, you may
re-engage the cruise control. SeeCruise Control on
page 3-10.
4-11

The ESC/TCS button is
located on the instrument
panel.
The traction control system can be turned off or back on
by pressing the ESC/TCS button. To disable both
traction control and ESC, press and hold the button from
ve to ten seconds.
When the ESC system is turned off, the TRACTION
OFF and ESC OFF messages appear, and the
ESC/TCS light comes on to warn the driver that both
traction control and ESC are disabled.
It is recommended that the system remain on for normal
driving conditions, but it may be necessary to turn the
system off if your vehicle is stuck in sand, mud, ice or
snow, and you want to “rock” your vehicle to attempt to
free it. It may also be necessary to turn off the system
when driving in extreme off-road conditions where high
wheel spin is required. SeeIf Your Vehicle is Stuck in
Sand, Mud, Ice, or Snow on page 4-26.ESC may also turn off automatically if it determines that
a problem exists with the system. The ESC OFF and
SERVICE ESC messages and the ESC/TCS light comes
on to warn the driver that ESC is disabled and requires
service. If the problem does not clear after restarting the
vehicle, see your dealer/retailer for service. SeeDIC
Warnings and Messages on page 3-43for more
information.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
Steering
Electric Power Steering
If the engine stalls while you are driving, the power
steering assist system will continue to operate until you
are able to stop your vehicle. If you lose power steering
assist because the electric power steering system is not
functioning, you can steer, but it will take more effort.
If you turn the steering wheel in either direction several
times until it stops, or hold the steering wheel in the
stopped position for an extended amount of time, you
may notice a reduced amount of power steering assist.
The normal amount of power steering assist should return
shortly after a few normal steering movements.

Driving in Rain and on Wet Roads
Rain and wet roads can reduce vehicle traction
and affect your ability to stop and accelerate. Always
drive slower in these types of driving conditions
and avoid driving through large puddles and
deep-standing or owing water.
{CAUTION:
Wet brakes can cause crashes. They might not
work as well in a quick stop and could cause
pulling to one side. You could lose control of
the vehicle.
After driving through a large puddle of water
or a car/vehicle wash, lightly apply the brake
pedal until the brakes work normally.
CAUTION: (Continued)
CAUTION: (Continued)
Flowing or rushing water creates strong
forces. Driving through owing water could
cause your vehicle to be carried away. If this
happens, you and other vehicle occupants
could drown. Do not ignore police warnings
and be very cautious about trying to drive
through owing water.
Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle’s tires so they actually ride on the water.
This can happen if the road is wet enough and you are
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
There is no hard and fast rule about hydroplaning.
The best advice is to slow down when the road is wet.
4-18

{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. The brakes will have
to do all the work of slowing down and they
could get so hot that they would not work well.
You would then have poor braking or even
none going down a hill. You could crash.
Always have the engine running and your
vehicle in gear when you go downhill.
Stay in your own lane. Do not swing wide or cut
across the center of the road. Drive at speeds
that let you stay in your own lane.
Top of hills: Be alert — something could be in your
lane (stalled car, accident).
Pay attention to special road signs (falling rocks
area, winding roads, long grades, passing or
no-passing zones) and take appropriate action.
Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You might want to put winter emergency supplies in
your vehicle.
Include an ice scraper, a small brush or broom, a
supply of windshield washer uid, a rag, some winter
outer clothing, a small shovel, a ashlight, a red
cloth, and a couple of reective warning triangles. And,
if you will be driving under severe conditions, include
a small bag of sand, a piece of old carpet, or a couple of
burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Also seeTires on page 5-49.
4-21

{CAUTION:
Fuel can spray out on you if you open the
fuel cap too quickly. If you spill fuel and then
something ignites it, you could be badly burned.
This spray can happen if your tank is nearly
full, and is more likely in hot weather. Open the
fuel cap slowly and wait for any hiss noise to
stop. Then unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or overll the
tank and wait a few seconds after you have nished
pumping before removing the nozzle. Clean fuel from
painted surfaces as soon as possible. SeeWashing
Your Vehicle on page 5-99.
When replacing the fuel cap, turn it clockwise until it
clicks. Make sure the cap is fully installed. The diagnostic
system can determine if the fuel cap has been left off or
improperly installed. This would allow fuel to evaporate
into the atmosphere. SeeMalfunction Indicator Lamp
on page 3-35.The CHECK GAS CAP message will be displayed on
the Driver Information Center (DIC) if the fuel cap is not
properly installed. SeeDIC Warnings and Messages
on page 3-43for more information.
{CAUTION:
If a re starts while you are refueling, do not
remove the nozzle. Shut off the ow of fuel
by shutting off the pump or by notifying the
station attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to
get the right type. Your dealer/retailer can get
one for you. If you get the wrong type, it may
not t properly. This may cause your malfunction
indicator lamp to light and may damage your
fuel tank and emissions system. SeeMalfunction
Indicator Lamp on page 3-35.
