Traction Control
System (TCS) (CTS-V)
Your vehicle has a traction control system 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 rear wheels are spinning or
beginning to lose traction. When this happens,
the system brakes the spinning wheel(s) and/or reduces
engine power to limit wheel spin.
You may feel or hear the system working, but this
is normal.
This warning light will
come on to let you know
if there’s a problem
with your traction
control system.
SeeTraction Control System (TCS) Warning Light on
page 3-45. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.

The traction control system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to. You
should turn the system off if your vehicle ever gets stuck
in sand, mud or snow and rocking the vehicle is
required. See “Rocking Your Vehicle” underIf You Are
Stuck: In Sand, Mud, Ice or Snow on page 4-32for
more information. See alsoWinter Driving on page 4-27
for information on using TCS when driving in snowy
or icy conditions.

Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It works like a
standard axle most of the time, but when one of the rear
wheels has no traction and the other does, this feature
will allow the wheel with traction to move the vehicle.
Stabilitrak®System
Your vehicle may be equipped with a vehicle stability
enhancement system called Stabilitrak®.Itisan
advanced computer controlled system that assists you
with directional control of the vehicle in difficult
driving conditions.
Stabilitrak
®activates when the computer senses a
discrepancy between your intended path and the
direction the vehicle is actually traveling. Stabilitrak
®
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, a Stability System Engaged
message will be displayed on the Driver Information
Center. SeeDIC Warnings and Messages on page 3-70.
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.
If there is a problem detected with Stabilitrak
®,a
Service Stability System message will be displayed on
the Driver Information Center. SeeDIC Warnings
and Messages on page 3-70. When this message is
displayed, the system is not operational. Driving should
be adjusted accordingly.
Stabilitrak
®comes on automatically whenever you start
your vehicle. To help assist you with directional
control of the vehicle, you should always leave the
system on. You can turn Stabilitrak
®off if you ever need
to through the TC (traction control) on/off button. See
Traction Control System (TCS) (CTS) on page 4-8
orTraction Control System (TCS) (CTS-V) on page 4-9.
If your vehicle is in cruise control when the Stabilitrak
®
activates, the cruise control will automatically disengage.
When road conditions allow you to safely use it again,
you may reengage the cruise control. See “Cruise
Control” underTurn Signal/Multifunction Lever on
page 3-10for more information.

{CAUTION:
If you spill fuel and then something ignites it,
you could be badly burned. Fuel can spray out
on you if you open the fuel cap too quickly.
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. Don’t top off or overll your
tank, and wait a few seconds after you’ve nished
pumping before you remove the nozzle. Clean fuel from
painted surfaces as soon as possible. SeeCleaning
the Outside of Your Vehicle on page 5-95.
When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make sure
you fully install the cap. 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 3-47.The Check Gas Cap message will appear on the Driver
Information Center (DIC) display if the fuel cap is not
reinstalled properly. SeeDIC Warnings and Messages
on page 3-70for 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 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 3-47.

When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A Change Engine Oil message in the DIC
will come on. Change your oil as soon as possible within
the next two times you stop for fuel. It is possible that,
if you are driving under the best conditions, the oil
life system may not indicate that an oil change is
necessary for over a year. However, your engine oil and
lter must be changed at least once a year and at
this time the system must be reset. Your dealer has
GM-trained service people who will perform this
work using genuine GM parts and reset the system. It is
also important to check your oil regularly and keep it
at the proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system

good hand cleaner. Wash or properly dispose of
clothing or rags containing used engine oil. See the
manufacturer’s warnings about the use and disposal
of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from
the lter before disposal. Never dispose of oil by
putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.

Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixture at the surge tank, but only when the
engine is cool.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
When replacing the pressure cap, make sure it
is hand-tight.
Coolant Surge Tank Pressure Cap
Notice:If the surge tank pressure cap is not tightly
installed, coolant loss and possible engine damage
may occur. Be sure the cap is properly and
tightly secured.
Engine Overheating
There are three engine hot messages that may be
displayed in the Driver Information Center (DIC).
SeeDIC Warnings and Messages on page 3-70
for more information.
Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be driven to
a safe place in an emergency. Should an overheated
engine condition exist, an overheat protection mode
which alternates ring groups of cylinders helps prevent
engine damage. In this mode, you will notice a loss
in power and engine performance. A low coolant and/or
engine overheat warning will indicate that an overheat
condition exists. Driving extended miles (km) and/or
towing a trailer in the overheat protection mode should
be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss and change the oil.
