Press and release this button to turn
off TCS. The TCS warning light will
be displayed on the instrument panel
cluster. The traction control system
can be turned back on by pressing
the TCS/StabiliTrak button.
If the system is limiting wheel spin
when the button is pressed, the
system will not turn off until there is
no longer a current need to limit
wheel spin. The system can
be turned back on at any time by
pressing the button again. If the TCS
light does not come on, TCS may
not be functioning properly and
the vehicle should be serviced at
your dealer/retailer.
Adding non-dealer/non-retailer
accessories can affect the vehicle’s
performance. SeeAccessories
and Modifications on page 5-3for
more information.All-Wheel Drive (AWD)
System
If the vehicle has all-wheel drive
(AWD), the AWD system operates
automatically without any action
required by the driver. If the front
drive wheels begin to slip, the rear
wheels will automatically begin to
drive the vehicle as required. There
may be a slight engagement noise
during hard use but this is normal.
This light is located on the
instrument panel cluster.
It will come on and stay on to
indicate there may be a problem
with the drive system and service is
required. If the light stays on, it must
be reset. To reset the light, turn the
ignition off and then back on again.
If the light stays on, see your
dealer/retailer for service.If the vehicle is exposed to extended
heavy AWD usage, the AWD system
will shut off to protect the system
from overheating. When the system
cools down, the AWD system will
activate again automatically; this
cool-down can take up to 20 minutes
depending on outside temperature
and vehicle use.
Steering
Electric Power Steering
If the vehicle has the electric power
steering system and the engine
stalls while driving, the power
steering assist system will continue
to operate until you are able to
stop the vehicle. If power steering
assist is lost because the electric
power steering system is not
functioning, the vehicle can be
steered but it will take more effort.

Engine Oil Additives / Engine
Oil Flushes
Do not add anything to the oil.
The recommended oils with the
starburst symbol that meet GM
Standard GM6094M are all that is
needed for good performance and
engine protection.
Engine oil system ushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and lter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A change engine oil light
comes on. SeeChange Engine Oil
Light on page 3-38. Change the oil
as soon as possible within the next
600 miles (1 000 km). It is possible
that, if driving under the best
conditions, the oil life system might
not indicate that an oil change is
necessary for over a year. However,
the engine oil and lter must be
changed at least once a year and at
this time the system must be reset.
Your dealer/retailer has trained
service people who will perform this
work using genuine parts and reset
the system. It is also important to
check the oil regularly and keep it at
the proper level.
If the system is ever reset
accidentally, the oil must be
changed at 3,000 miles (5 000 km)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where the oil is
changed prior to a change engine
oil light being turned on, reset the
system.
After changing the engine oil, reset
the system:
1. Turn the ignition key to ON/RUN
with the engine off.
2. Fully press and release the
accelerator pedal three times
within ve seconds.
If the change engine oil light is
not on, the system is reset.
If the light comes on again and stays
on for 30 seconds at the next ignition
cycle, it did not reset. The system
needs to be reset again.
