Operate the engine and transaxle gently to
allow the oil to warm up and lubricate all
moving parts.
Your vehicle has a Computer-Controlled
Cranking System. This feature assists
in starting the engine and protects
components. If the ignition key is turned to the
START position, and then released when
the engine begins cranking, the engine
will continue cranking for a few seconds or
until the vehicle starts. If the engine does not
start and the key is held in START for
many seconds, cranking will be stopped after
15 seconds to prevent cranking motor
damage. To prevent gear damage, this system
also prevents cranking if the engine is
already running. Engine cranking can be
stopped by turning the ignition switch to the
ACCESSORY or OFF position.
Notice:Cranking the engine for long periods
of time, by returning the key to the START
position immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or
−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator pedal all
the way to the oor and holding it there as
you hold the key in START for up to a
maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If
the vehicle starts brie y but then stops again,
do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transaxle gently until the
oil warms up and lubricates all moving parts.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.

BATTERY VOLTAGE
This display shows the current battery voltage.
If the voltage is in the normal range, the value
will display. For example, the display may read
BATTERY VOLTAGE 13.2 VOLTS. If the voltage
is low, the display will show LOW. If the voltage is
high, the display will show HIGH. Your vehicle’s
charging system regulates voltage based on the
state of the battery. The battery voltage may
uctuate when viewing this information on the DIC.
This is normal. SeeCharging System Light on
page 229for more information.
If there is a problem with the battery charging
system, the DIC will display a message. SeeDIC
Warnings and Messages on page 246and
Electric Power Management on page 201for
more information.

Items
T
(Vehicle Information):The following display
menu items can be displayed by pressing the
vehicle information button:
OIL LIFE REMAINING
If the vehicle has this display, it shows the
estimated oil life remaining. If you see 99% OIL
LIFE REMAINING on the display, that means that
99% of the current oil life remains.
When the oil life is depleted, the CHANGE ENGINE
OIL SOON message will appear on the display.
You should change the oil as soon as possible.
In addition to the engine oil life system monitoring
the oil life, additional maintenance is recommended
in the Maintenance Schedule in this manual. See
Scheduled Maintenance on page 465andEngine
Oil on page 365.
Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.

will show 100% when the system is reset.
UNITS
This display allows you to select between English
or Metric units of measurement. Once in this
display, press the set/reset button to select
between ENGLISH or METRIC units.
PARKING ASSIST
If your vehicle has the Ultrasonic Front and Rear
Parking Assist (UFRPA) system, this display
allows the system to be turned on or off. Once
in this display, press the set/reset button to select
between ON or OFF. If you choose ON, the
system will be turned on. If you choose OFF,
the system will be turned off. The UFRPA system
automatically turns back on after each vehicle
start. When the UFRPA system is turned off and
the vehicle is shifted out of PARK (P), the DIC
will display the PARKING ASSIST OFF message
as a reminder that the system has been turned
off. SeeDIC Warnings and Messages on page 246
andUltrasonic Front and Rear Parking Assist
(UFRPA) on page 202for more information.
FRONT TIRES or REAR TIRES
The pressure for each tire can be viewed in the
DIC. The tire pressure will be shown in either
pounds per square inch (psi) or kilopascals (kPa).
Press the vehicle information button until the
DIC displays FRONT TIRES PSI (kPa) LEFT ##
RIGHT ##. Press the vehicle information button
again until the DIC displays REAR TIRES
PSI (kPa) LEFT ## RIGHT ##.
If a low or high tire pressure condition is detected
by the system while driving, a message advising
you to check the pressure in a speci c tire will
appear in the display. SeeIn ation - Tire Pressure
on page 411andDIC Warnings and Messages on
page 246for more information.
If the tire pressure display shows dashes instead of
a value, there may be a problem with your vehicle.
If this consistently occurs, see your dealer for

If you are in an area of extreme cold, where the
temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both provide
easier cold starting and better protection for
the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM6094M are all you need for good
performance and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you
know 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
will be indicated can vary considerably. For the oil
life system to work properly, you must reset the
system every time the oil is changed.When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A CHANGE ENGINE OIL SOON
message in the Driver Information Center (DIC) will
come on. Change the oil as soon as possible
within the next 600 miles (1 000 km). It is possible
that, if you are 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 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, you must
change the oil at 3,000 miles (5 000 km) since
the last oil change. Remember to reset the oil life
system whenever the oil is changed.
