2004 CADILLAC SRX cooling

Liftgate
To unlock the liftgate from the outside, turn the key in
the driver’s door cylinder counterclockwise or use the
remote keyless entry transmitter. To lock the liftgate
using the key, turn the key clockwise in the driver’s door.
Open the liftgate using the handle located below the
license plate. Once slightly opened, the liftgate will rise
by itself.
{CAUTION:
It can be dangerous to drive with the liftgate
open because carbon monoxide (CO) gas can
come into your vehicle. You can not 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. SeeDual Climate Control
System on page 3-26.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-33.
To close the liftgate, pull down on the handle, then
rmly shut the liftgate. Don’t drive with the liftgate open,
even slightly. SeeEngine Exhaust on page 2-33.

Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode,
the air conditioning compressor and the fan speed.
AUTO will appear on the display.1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the warmest
temperature setting, the system will remain in
manual mode at that temperature and it will not go
into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting.
The length of time needed for warm up will depend
on the outside temperature and the length of
time that has elapsed since your vehicle was last
driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature,
if necessary.

Engine Coolant Temperature
Warning Light
This light tells you that
your engine is very hot.
This light will come on when you rst start the vehicle
as a check to let you know that the light is working. It will
go out after a few seconds. If the light does not come
on, the bulb may be burned out. See your dealer
for assistance in changing the bulb.
If the light does not go out or if the light comes on and
stays on while you are driving, your vehicle may
have a problem with the cooling system. You should
stop the vehicle and turn off the engine as soon
as possible to avoid damage to the engine. A warning
chime will sound when this light is on, also.
SeeEngine Overheating on page 5-28.
Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature. If the gage
pointer moves into
the shaded area, the
engine is too hot.
That reading means the same thing as the warning
light – the engine coolant is very hot. SeeEngine
Overheating on page 5-28.

Change Trans (Transmission) Fluid
This message indicates that the life of the transmission
uid has expired and it should be changed within
200 miles (320 km). SeeScheduled Maintenance on
page 6-4andRecommended Fluids and Lubricants on
page 6-13for the proper uid and change intervals.
When you reset the Change Trans Fluid message by
clearing it from the display, you still must reset the
transmission uid life monitor separately. For more
information on resetting the transmission uid life
monitor, seeAutomatic Transmission Fluid on
page 5-24.
Check Brake Fluid
This message will display if the ignition is in ON to
inform the driver that the brake uid level is low.
Have the brake system serviced by a technician as
soon as possible. SeeBrake System Warning Light on
page 3-41for more information.
Check Coolant Level
This message will appear when there is a low level of
engine coolant. Have the cooling system serviced
by a technician as soon as possible. SeeEngine
Coolant on page 5-25for more information.
Check Gas Cap
When this message appears on the display, the gas cap
has not been fully tightened. You should recheck the
gas cap to ensure that it’s on and tightened properly.
Check Washer Fluid
When this message appears on the display, it means that
your vehicle is low on windshield washer uid. You should
rell the tank as soon as possible. SeeWindshield
Washer Fluid on page 5-38for more information.
Driver Door Ajar
When this message appears on the display, it means
that the driver’s door was not closed completely.
You should make sure that the driver’s door is closed
completely.

After Off-Road Driving
Remove any brush or debris that has collected
on the underbody, chassis or under the hood.
These accumulations can be a re hazard.
After operation in mud or sand, have the brake linings
cleaned and checked. These substances can cause
glazing and uneven braking. Check the body structure,
steering, suspension, wheels, tires and exhaust
system for damage. Also, check the fuel lines and
cooling system for any leakage.
Your vehicle will require more frequent service due to
off-road use. Refer to the Maintenance Schedule
for additional information.
Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired — by alcohol or drugs, with night vision
problems, or by fatigue.

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.
Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you go
down a steep or long hill.
{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.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have
to do all the work of slowing down. They 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.
Always have your engine running and your
vehicle in gear when you go downhill.
Know how to go uphill. You may want to shift down to
a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could
be something in your lane, like a stalled car or an
accident.
You may see highway signs on mountains that warn
of special problems. Examples are long grades,
passing or no-passing zones, a falling rocks area or
winding roads. Be alert to these and take appropriate
action.
4-39

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
start your engine,
shift into a gear, and
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’re
pulling a trailer. SeeScheduled Maintenance on
page 6-4for more information. Things that are especially
important in trailer operation are automatic transmission
uid (don’t overll), engine oil, axle lubricant, drive
belt, cooling system and brake system. Each of these is
covered in this manual, and the Index will help you
nd them quickly. If you’re trailering, it’s a good idea to
review this information before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating
on page 5-28.
