This is because different driving conditions produce
different fuel economies. Generally, freeway driving
produces better fuel economy than city driving.
If your vehicle is low on fuel, the FUEL LEVEL
LOW message will be displayed. See “FUEL
LEVEL LOW” underDIC Warnings and Messages
on page 198for more information.

(Vehicle Information):Press this button to
scroll through the following displays:
OIL LIFE
Press the vehicle information button until OIL LIFE
REMAINING displays. This display shows an
estimate of the oil’s remaining useful life. If you see
99% OIL LIFE REMAINING on the display, that
means 99% of the current oil life remains. The
engine oil life system will alert you to change your
oil on a schedule consistent with your driving
conditions.When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on the
display. See “CHANGE ENGINE OIL SOON” under
DIC Warnings and Messages on page 198. You
should change your oil as soon as possible. See
Engine Oil on page 344. In addition to the engine
oil life system monitoring the oil life, additional
maintenance is recommended in the Maintenance
Schedule in this manual. SeeScheduled
Maintenance on page 439for more information.
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.
It cannot be reset accurately until the next oil
change. To reset the engine oil life system, see
Engine Oil Life System on page 347.UNITS
Press the vehicle information button until UNITS
displays. 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.

When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit,
do not, under any circumstances, stop and back up.
Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted.
Reduce your speed according to your speedometer,
not to your sense of motion. After driving for any
distance at higher speeds, you may tend to think you
are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If
you must start when you are not fresh — such as
after a day’s work — do not plan to make too many
miles that rst part of the journey. Wear comfortable
clothing and shoes you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course,
you will nd experienced and able service experts
in GM dealerships all across North America.
They will be ready and willing to help if you need it.Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the lenses
clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all in ated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
Maps:Do you have up-to-date maps?

Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing
additive called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you
buy gasoline whether the fuel contains MMT.
General Motors recommends against the use of
such gasolines. Fuels containing MMT can reduce
the life of spark plugs and the performance of
the emission control system may be affected. The
malfunction indicator lamp may turn on. If this
occurs, return to your dealer for service.
Fuels in Foreign Countries
If you plan on driving in another country outside
the United States or Canada, the proper fuel may
be hard to nd. Never use leaded gasoline or
any other fuel not recommended in the previous
text on fuel. Costly repairs caused by use of
improper fuel would not be covered by your
warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business
in the country where you will be driving.
Filling the Tank
{CAUTION:
Fuel vapor burns violently and a fuel re
can cause bad injuries. To help avoid
injuries to you and others, read and follow
all the instructions on the pump island.
Turn off your engine when you are
refueling. Do not smoke if you are near
fuel or refueling your vehicle. Keep
sparks, ames, and smoking materials
away from fuel. Do not leave the fuel
pump unattended when refueling your
vehicle. This is against the law in some
places. Keep children away from the fuel
pump; never let children pump fuel.

What Kind of Engine Oil to Use
Look for two things:
GM6094M
Your vehicle’s engine requires oil meeting GM
Standard GM6094M. You should look for
and use only an oil that meets GM Standard
GM6094M.
SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is
best for your vehicle. 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.
These numbers on an oil container show its
viscosity, or thickness. Do not use other
viscosity oils such as SAE 20W-50.
Oils meeting these
requirements should
also have the starburst
symbol on the
container. This symbol
indicates that the oil
has been certi ed by the
American Petroleum
Institute (API).
You should look for this information on the oil
container, and use only those oils that are identi ed
as meeting GM Standard GM6094M and have the
starburst symbol on the front of the oil container.
