ECU SATURN RELAY 2005 Service Manual

When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R) if the ultrasonic sensors are not kept
clean. So be sure to keep your rear bumper free of mud,
dirt, snow, ice and slush. Other conditions that may
affect system performance include things like the
vibrations from a jackhammer or the compression of air
brakes on a very large truck. If after cleaning the
rear bumper and then driving forward at least 15 mph
(25 km/h), the display continues to ash red, see
your dealer.
If a trailer was attached to your vehicle, or a bicycle or
an object was on the back of, or hanging out of your
liftgate during your last drive cycle, the light may
also ash red. The light will continue to ash whenever
in REVERSE (R) until your vehicle is driven forward
at least 15 mph (25 km/h) without any obstructions
behind the vehicle.
Accessory Power Outlets
Your vehicle may be equipped with a front accessory
power outlet located below the climate controls on
the instrument panel. It can be used to plug in electrical
equipment such as a cellular telephone or CB radio.
Pull the cover down to use the accessory power outlet.
When not in use, keep the cover on.
The rear accessory power outlet is located on the rear
compartment on the driver’s side.
To remove the cover, pull the tab on the cover and pull
it off. To put the cover back on, line up the tabs at
the back of the cover and put the cover in place. Push
down the tab to secure the cover. When not in use,
always cover the rear accessory power outlet with the
protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem see your retailer for additional information
on accessory power outlets.

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 5-52.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 your tires meet
the road probably have good traction.
However, if there is snow or ice between your 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.

The Certication/Tire label also tells you the maximum
weights for the front and rear axles, called the Gross
Axle Weight Rating (GAWR). To nd out the actual loads
on your front and rear axles, you need to go to a
weigh station and weigh your vehicle. Your retailer can
help you with this. Be sure to spread out your load
equally on both sides of the centerline.
Never exceed the GVWR for your vehicle or the Rating
GAWR for either the front or rear axle.
{CAUTION:
Do not load your vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or either
the maximum front or rear Gross Axle Weight
Rating (GAWR). If you do, parts on your
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of your vehicle.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.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.

Driving with a Trailer
{CAUTION:
If you have a rear-most window open and you
pull a trailer with your vehicle, carbon
monoxide (CO) could come into your vehicle.
You cannot see or smell CO. It can cause
unconsciousness or death. SeeEngine
Exhaust on page 2-40. To maximize your safety
when towing a trailer:
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the rear-most windows closed.
If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. 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 3-24.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.
