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 L (Low), the
vehicle may need service.
When this light is on solid, the system will not limit
wheel spin. Adjust your driving accordingly.
Check the 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 the 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 4-38 for
more information on the messages associated with
this light.
To limit wheel spin, especially in slippery road
conditions, ETS should always be left on. But the
system can be turned off if needed. To turn the system off, shift to L (Low) or R (Reverse).
When the system is turned off, the ETS indicator/warning
light will come on and stay on and the TRACTION OFF
message will be displayed when the gear shift is in
L (Low). The indicator/warning light and message will not
come on when the gear shift is in R (Reverse). If the ETS
is limiting wheel spin when the transmission is shifted to
L (Low) or R (Reverse) to turn the system off, the
indicator/warning light and TRACTION OFF will come on
in L (Low). But the system will not turn off right away.
It will wait until there is no longer a current need to limit
wheel spin. See
DIC Warnings and Messages on
page 4-38 for more information on the messages
associated with this light.
The system can be turned back on at any time by
shifting to D (Automatic Overdrive) or I (Intermediate).
The ETS indicator/warning light should go off.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. See Accessories and
Modi cations on page 6-3 for more information.

{WARNING:
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 the 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 overfill the
tank and wait a few seconds after you have finished
pumping before removing the nozzle. Clean fuel from
painted surfaces as soon as possible. See Washing Your
Vehicle on page 6-97.
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. See Malfunction
Indicator Lamp on page 4-30 . The CHECK GAS CAP message displays on the Driver
Information Center (DIC) if the fuel cap is not properly
installed. See
DIC Warnings and Messages on
page 4-38 for more information.
{WARNING:
If a fire starts while you are refueling, do not
remove the nozzle. Shut off the flow 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 the malfunction indicator lamp to
light and may damage the fuel tank and emissions
system. See Malfunction Indicator Lamp on
page 4-30.

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to change
your engine oil and filter 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 OIL SOON
message being turned on, reset the system.
After changing the engine oil, the system must be reset:1. Turn the ignition to ON/RUN, with the engine off.
2. Press the information and reset buttons on the Driver Information Center (DIC) at the same
time to enter the personalization menu. See DIC
Vehicle Personalization on page 4-43 .
3. Press the information button to scroll through the available personalization menu modes until the
DIC display shows OIL-LIFE RESET.
4. Press and hold the reset button until the DIC display shows ACKNOWLEDGED. This will tell you
the system has been reset.
5. Turn the key to LOCK/OFF. If the CHANGE OIL SOON message comes back on
when the vehicle is started, the engine oil life system
has not reset. Repeat the reset procedure.What to Do with Used Oil
Used engine oil contains certain elements that can be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a 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
filter 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. Recycle it by taking it to a
place that collects used oil.
6-17
Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver when a
low tire pressure condition exists. If your vehicle has this
feature, TPMS sensors are mounted onto each tire and
wheel assembly, excluding the spare tire and wheel
assembly, if the vehicle has one. The TPMS sensors
monitor the air pressure in the vehicle’s tires and transmit
the tire pressure readings to a receiver located in the
vehicle.When a low tire pressure
condition is detected, the
TPMS turns on the low tire
pressure warning light
located on the instrument
panel cluster.
At the same time a message to check the pressure in a
specific tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light and the
DIC warning message come on at each ignition cycle
until the tires are inflated to the correct inflation pressure.
Using the DIC, tire pressure levels can be viewed by the
driver. For additional information and details about the
DIC operation and displays see DIC Operation and
Displays on page 4-36 andDIC Warnings and Messages
on page 4-38. The low tire pressure warning light may come on in cool
weather when the vehicle is first started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inflated to the proper pressure.
A Tire and Loading Information label shows the size of
your vehicle’s original equipment tires and the correct
inflation pressure for your vehicle’s tires when they are
cold. See
Loading the Vehicle on page 5-24 , for an
example of the Tire and Loading Information label and
its location on your vehicle. Also see In ation - Tire
Pressure on page 6-55 .
Your vehicle’s TPMS system can warn you about a low
tire pressure condition but it does not replace normal
tire maintenance. See Tire Inspection and Rotation
on page 6-62 andTires on page 6-48.
Notice: Using non-approved tire sealants could
damage the Tire Pressure Monitor System (TPMS)
sensors. TPMS sensor damage caused by using
an incorrect tire sealant is not covered by the
vehicle warranty. Always use the GM approved tire
sealant available through your dealer/retailer.
Factory-installed Tire Inflator Kits use a GM approved
liquid tire sealant. Using non-approved tire sealants
could damage the TPMS sensors. See Tire Sealant and
Compressor Kit on page 6-72 for information regarding
the inflator kit materials and instructions.
6-58
TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of
the TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
flashes for about one minute and then stays on for the
remainder of the ignition cycle. A DIC warning message
is also displayed. The low tire warning light and DIC
warning message come on at each ignition cycle until the
problem is corrected. Some of the conditions that can
cause the malfunction light and DIC message to come
on are:
•One of the road tires has been replaced with the
spare tire, if the vehicle has one. The spare tire does
not have a TPMS sensor. The TPMS malfunction
light and DIC message should go off once you
re-install the road tire containing the TPMS sensor.
•The TPMS sensor matching process was started but
not completed or not completed successfully after
rotating the vehicle’s tires. The DIC message and
TPMS malfunction light should go off once the TPMS
sensor matching process is performed successfully.
See “TPMS Sensor Matching Process” later in this
section.
•One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your dealer/
retailer for service.
•Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels. Tires
and wheels other than those recommended for your
vehicle could prevent the TPMS from functioning
properly. SeeBuying New Tires on page 6-64 .
•Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or signal
a low tire condition. See your dealer/retailer for service if
the TPMS malfunction light and DIC message comes on
and stays on.

Tire Inspection and Rotation
We recommend that you regularly inspect the
vehicle’s tires, including the spare tire, if the
vehicle has one, for signs of wear or damage. See
When It Is Time for New Tires on page 6-64 for
more information.
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km). See Scheduled Maintenance
on page 7-3.
The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This
will ensure that the vehicle continues to perform
most like it did when the tires were new.
Any time you notice unusual wear, rotate the tires
as soon as possible and check wheel alignment.
Also check for damaged tires or wheels. See
When It Is Time for New Tires on page 6-64 and
Wheel Replacement on page 6-68 .
6-62
Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). SeeTire Inspection
and Rotation on page 6-62 .
Scheduled Maintenance
When the Change Oil Soon Message
Displays
Change engine oil and filter. See Engine Oil on
page 6-13. An Emission Control Service.
When the Change Oil Soon message displays, service
is required for the vehicle as soon as possible, within
the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset.
Your dealer/retailer has trained service technicians who
will perform this work and reset the system. If the
engine oil life system is reset accidentally, service the
vehicle within 5 000 km/3,000 miles since the last
service. Reset the oil life system whenever the oil is
changed. See Engine Oil Life System on page 6-16 .When the Change Oil Soon message displays, certain
services, checks, and inspections are required. The
services described for Maintenance
Ishould be
performed at every engine oil change. The services
described for Maintenance IIshould be performed when:
