Radio Reception
You may experience frequency interference and
static during normal radio reception if items
such as cellphone chargers, vehicle convenience
accessories, and external electronic devices
are plugged into the accessory power outlet. If
there is interference or static, unplug the item from
the accessory power outlet.
AM
The range for most AM stations is greater than for
FM, especially at night. The longer range can
cause station frequencies to interfere with each
other. For better radio reception, most AM
radio stations will boost the power levels during
the day, and then reduce these levels during
the night. Static can also occur when things like
storms and power lines interfere with radio
reception. When this happens, try reducing the
treble on your radio.

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 will
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 meet GM Standard
GM6094M are all you will 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 OIL SOON message will
come on. SeeDIC Warnings and Messages on
page 256. Change your 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 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 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 whenever the oil is changed.
