ECU SATURN RELAY 2007 Workshop Manual

Oil Pressure Light
If you have low engine
oil pressure, this light
will stay on after
you start your engine, or
come on when you
are driving.
This indicates that your engine is not receiving
enough oil. The engine could be low on oil,
or could have some other oil problem. Have it
xed immediately by your GM retailer.
The oil light could also come on in three other
situations:
When the ignition is on but the engine is not
running, the light will come on as a test to show
you it is working. The light will go out when you
turn the ignition on. If it does not come on with
the ignition on, you may have a problem with
the fuse or bulb. Have it xed right away.
If you are idling at a stop sign, the light may
blink on and then off.
If you make a hard stop, the light may come on
for a moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others could
be burned. Check your oil as soon as
possible and have your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency
supplies in your vehicle.
Also seeTires on page 462.Include an ice scraper, a small brush or broom,
a supply of windshield washer uid, a rag,
some winter outer clothing, a small shovel, a
ashlight, a red cloth, and a couple of reective
warning triangles. And, if you will be driving under
severe conditions, include a small bag of sand,
a piece of old carpet, or a couple of burlap bags
to help provide traction. Be sure you properly
secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where the tires
meet the road probably have good traction.
However, if there is snow or ice between the
tires and the road, you can have a very slippery
situation. You will have a lot less traction, or
grip, and will need to be very careful.

If you put things inside your vehicle — like
suitcases, tools, packages, or anything else, they
will go as fast as the vehicle goes. If you have
to stop or turn quickly, or if there is a crash, they
will keep going.
{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
Do not leave an unsecured child
restraint in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down
unless you need to.
Towing
Towing Your Vehicle
Consult your retailer or a professional towing
service if you need to have your disabled vehicle
towed. SeeRoadside Assistance Program on
page 543.
If you want to tow your vehicle behind another
vehicle for recreational purposes (such as behind
a motorhome), see “Recreational Vehicle
Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your
vehicle behind another vehicle — such as behind
a motorhome. The two most common types
of recreational vehicle towing are known as
“dinghy towing” (towing your vehicle with all
four wheels on the ground) and “dolly towing”
(towing your vehicle with two wheels on the
ground and two wheels up on a device know
as a “dolly”).

CAUTION: (Continued)
This will bring fresh, outside air into
your vehicle. Do not use the climate
control setting for maximum air
because it only recirculates the air
inside your vehicle. SeeClimate
Control System on page 205orDual
Climate Control System on page 209.
Towing a trailer requires a certain amount of
experience. Before setting out for the open road,
you will want to get to know your rig. Acquaint
yourself with the feel of handling and braking
with the added weight of the trailer. And always
keep in mind that the vehicle you are driving
is now a good deal longer and not nearly
as responsive as your vehicle is by itself.Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector,
lamps, tires, and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving
and then apply the trailer brake controller by hand
to be sure the brakes are working. This lets you
check your electrical connection at the same time.
During your trip, check occasionally to be sure
that the load is secure, and that the lamps and
any trailer brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead
as you would when driving your vehicle without
a trailer. This can help you avoid situations
that require heavy braking and sudden turns.
Passing
You will need more passing distance up ahead
when you are towing a trailer. And, because
you are a good deal longer, you will need to
go much farther beyond the passed vehicle
before you can return to your lane.
