fuel type SATURN ION 2007 Owners Manual

DRIVE (D):This position is for normal driving with
the automatic transaxle. It provides the best fuel
economy for your vehicle. If you need more power
for passing, and you are:
Going less than about 35 mph (55 km/h), push
your accelerator pedal about halfway down.
Going about 35 mph (55 km/h), push
your accelerator all the way down.
Downshifting the transaxle in slippery road
conditions could result in skidding, see “Skidding”
underLoss of Control on page 233.
INTERMEDIATE (I):This position is also used for
normal driving. However, it reduces vehicle speed
without using your brakes for slight downgrades
where the vehicle would otherwise accelerate due
to steepness of grade. If constant upshifting or
downshifting occurs while driving up steep hills, this
position can be used to prevent repetitive types of
shifts. You might choose INTERMEDIATE (I)
instead of DRIVE (D) when driving on hilly, winding
roads and when towing a trailer, so that there is less
shifting between gears.LOW (L):This position reduces vehicle speed
more than INTERMEDIATE (I) without actually
using your brakes. You can use it on very steep
hills, or in deep snow or mud. If the shift lever
is put in LOW (L), the transaxle will not shift into
LOW (L) until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the transaxle.
If you are stuck, do not spin the tires. When
stopping on a hill, use the brakes, or parking
brake to hold the vehicle in place.

If your vehicle has the 2.4L L4 engine (VIN Code B)
or the 2.0L Supercharged engine (VIN Code P), use
premium unleaded gasoline with a posted octane
rating of 91 or higher. You may also use regular
unleaded gasoline rated at 87 octane or higher, but
your vehicle’s acceleration may be slightly reduced,
and you may notice a slight audible knocking noise,
commonly referred to as spark knock. If the octane
is less than 87, you may notice a heavy knocking
noise when you drive. If this occurs, use a gasoline
rated at 87 octane or higher as soon as possible.
Otherwise, you might damage your engine. If you
are using gasoline rated at 87 octane or higher and
you hear heavy knocking, your engine needs
service.
Gasoline Specications
At a minimum, gasoline should meet ASTM
specication D 4814 in the United States or
CAN/CGSB-3.5 in Canada. Some gasolines may
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT). Saturn recommends against the use
of gasolines containing MMT. SeeAdditives on
page 273for additional information.
California Fuel
If your vehicle is certied to meet California
Emissions Standards, it is designed to operate on
fuels that meet California specications. See the
underhood emission control label. If this fuel is not
available in states adopting California emissions
standards, your vehicle will operate satisfactorily on
fuels meeting federal specications, but emission
control system performance may be affected. The
malfunction indicator lamp may turn on and your
vehicle may fail a smog-check test. SeeMalfunction
Indicator Lamp on page 174. If this occurs, return to
your authorized Saturn retailer for diagnosis. If it is
determined that the condition is caused by the type
of fuel used, repairs may not be covered by your
warranty.
Additives
To provide cleaner air, all gasolines in the United
States are now required to contain additives
that will help prevent engine and fuel system
deposits from forming, allowing your emission
control system to work properly. In most cases,
you should not have to add anything to your fuel.

{CAUTION:
If you spill fuel and then something
ignites it, you could be badly burned. Fuel
can spray out on you if you open the fuel
cap too quickly. This spray can happen if
your 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 overll
the tank and wait a few seconds after you have
nished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon
as possible. SeeWashing Your Vehicle on
page 369.
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. SeeMalfunction Indicator Lamp on
page 174.
In addition, the CHECK GAS CAP message will
be displayed in the Message Center if the fuel cap
is not properly reinstalled. SeeCheck Gas Cap
Message on page 185for more information.
{CAUTION:
If a re starts while you are refueling, do
not remove the nozzle. Shut off the ow 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 retailer can get
one for you. If you get the wrong type, it may
not t properly. This may cause your
malfunction indicator lamp to light and may
damage your fuel tank and emissions system.

Vehicle Data Collection and Event
Data Recorders
Your vehicle, like other modern motor vehicles,
has a number of sophisticated computer
systems that monitor and control several
aspects of the vehicle’s performance. Your
vehicle uses on-board vehicle computers
to monitor emission control components to
optimize fuel economy, to monitor conditions
for airbag deployment and, if the vehicle
has the Anti-lock Brake System (ABS), to
provide anti-lock braking and to help the driver
control the vehicle in difficult driving
situations. Some information may be stored
during regular operations to facilitate repair of
detected malfunctions; other information is
stored only in a crash event by computer
systems, such as those commonly called Event
Data Recorders (EDR).
In a crash event, computer systems, such as
the airbag Sensing and Diagnostic Module
(SDM) in your vehicle may record information
about the condition of the vehicle and how
it was operated, such as data related to engine
speed, brake application, throttle position,
