cooling SATURN RELAY 2007 Owners Manual

Liftgate
To unlock or lock the liftgate from the outside, use
the remote keyless entry transmitter. For more
information, seeRemote Keyless Entry System
Operation on page 107.
You can also use the power door lock switch to
lock and unlock the liftgate.
Open the liftgate using the handle located above
the license plate. Once slightly opened, the
liftgate will rise by itself. Lamps in the rear of the
vehicle will come on, illuminating the rear
cargo area.
Notice:If you open the liftgate without
checking for overhead obstructions such as a
garage door, you could break the liftgate
glass. Always check to make sure the area
above the liftgate is clear before opening it.{CAUTION:
It can be dangerous to drive with the
liftgate open because carbon monoxide
(CO) gas can come into your vehicle.
You cannot see or smell CO. It can
cause unconsciousness and even death.
If you must drive with the liftgate open or
if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
and select the control setting that
will force outside air into your vehicle.
CAUTION: (Continued)

Cargo Lamp
The cargo lamp is located in the rear of your
vehicle, above the liftgate opening, and does not
have a switch. The cargo lamp will come on
each time you open a door, unless you turn on the
interior lamps override. SeeInterior Lamps
Control on page 195.
Electric Power Management
This vehicle has Electric Power Management
(EPM), an advanced control system. It estimates
the battery’s temperature and state of charge
and then adjusts the voltage for best performance
and extended life of the battery.When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage, you may
see the voltage move up or down. This is normal.
If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very high
electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.

Cigarette Lighter
Your vehicle may have a cigarette lighter. To use
the lighter, located on the instrument panel
below the climate controls, push it in all the way
and let go. When it is ready, it will pop back out
by itself.
Notice:Holding a cigarette lighter in while it
is heating will not allow the lighter to back
away from the heating element when it is hot.
Damage from overheating may occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in
while it is heating.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle. Never
put ammable items in the ashtray.
Climate Controls
Climate Control System
With this system you can control the heating,
cooling and ventilation for your vehicle.

Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity, or moisture, condensing on the cool
window glass. This can be minimized if the climate
control system is used properly. There are
two modes to clear fog or frost from your
windshield. Use the defog mode to clear the
windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog
or frost from the windshield more quickly.
Turn the right knob to select the defog or
defrost mode.
-(Defog):This mode directs air to the
windshield and the oor outlets. When you select
this mode, the system runs the air-conditioning
compressor unless the outside temperature is at or
below freezing. The recirculation mode cannot
be selected while in the defog mode.

Hill and Mountain Roads
Driving on steep hills or mountains is different
from driving in at or rolling terrain.If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that
can make your trips safer and more enjoyable.
Keep your vehicle in good shape. Check
all uid levels and also the brakes, tires,
cooling system, and transaxle. These parts
can work hard on mountain roads.
{CAUTION:
If you do not shift down, your brakes
could get so hot that they would not work
well. You would then have poor braking or
even none going down a hill. You could
crash. Shift down to let your engine assist
your brakes on a steep downhill slope.

Three important considerations have to do
with weight:
Weight of the trailer
Weight of the trailer tongue
Weight on your vehicle’s tires
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig.
For example, speed, altitude, road grades,
outside temperature, and how much your
vehicle is used to pull a trailer are all important.It can also depend on any special equipment that
you have on your vehicle, and the amount of
tongue weight the vehicle can carry. See “Weight
of the Trailer Tongue” later in this section for
more information.
Maximum trailer weight is calculated assuming
only the driver is in the tow vehicle and it has all
the required trailering equipment. The weight
of additional optional equipment, passengers and
cargo in the tow vehicle must be subtracted
from the maximum trailer weight.
Look in the following chart to nd the maximum
trailer weight for your vehicle.
Vehicle Axle Ratio Maximum Trailer Weight *GCWR
Two-Wheel-Drive 3.29 3,500 lbs (1 588 kg) 8,500 lbs (3 856 kg)
Any vehicle without the V92 trailering package or heavy-duty cooling package is limited to a 2,000 lb (907 kg)
trailer rating and a 7,000 lb (3 175 kg) GCWR.
*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle
and trailer including any passengers, cargo, equipment and conversion. The GCWR for your vehicle should not
be exceeded.
You can ask your retailer for our trailering
information or advice, or you can write us at the
address listed in your Warranty and Owner
Assistance Information Booklet.In Canada, write to:

Safety Chains
You should always attach chains between your
vehicle and your trailer. Cross the safety
chains under the tongue of the trailer to help
prevent the tongue from contacting the road if it
becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for
attaching safety chains and do not attach them to
the bumper. Always leave just enough slack so
you can turn with your rig. Never allow safety
chains to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 lbs (450 kg)
loaded, then it needs its own brakes — and
they must be adequate. Be sure to read and follow
the instructions for the trailer brakes so you will
be able to install, adjust, and maintain them
properly.
Because your vehicle may have anti-lock brakes,
do not try to tap into your vehicle’s brake
system. If you do, both brake systems will not
work well, or at all.
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 151.
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.
CAUTION: (Continued)

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal
down while you do the following:
Start your engine.
Shift into a gear.
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the
chocks.
4. Stop and have someone pick up and store
the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when
you are pulling a trailer. See the Maintenance
Schedule for more on this. Things that are
especially important in trailer operation are
automatic transaxle uid, engine oil, belts, cooling
system, and brake system. Each of these is
covered in this manual, and the Index will help
you nd them quickly. If you are trailering, it is a
good idea to review these sections before you
start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.
Trailer Wiring Harness
Your vehicle may have a trailer wiring harness
package located in the glove box. It can be
connected from the rear of your vehicle to your
trailer. Contact your retailer for more information.
