2007 CADILLAC SRX cooling

Manual Liftgate Operation
With the doors unlocked, the power liftgate can
always be manually opened and closed.
To open the liftgate, pull up on the handle on the
outside of the liftgate. To close the liftgate,
use the pull cup to lower the liftgate and close.
The liftgate latch will power cinch to closed
position. Do not force the liftgate during a
power cycle.
Always close the liftgate before driving.{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. See
Dual Climate Control System on
page 189.
If you have air outlets on or under the
instrument panel, open them all the
way. SeeEngine Exhaust on page 132.

Electric Power Management
The vehicle has Electric Power Management
(EPM) that estimates the battery’s temperature and
state of charge. It 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 or voltage
display on the Driver Information Center (DIC), 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.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 220.

Climate Controls
Dual Climate Control System
With this system you can control the heating,
cooling, defrosting, and ventilation for the vehicle.
Automatic Operation
The climate control system automatically adjusts
the air temperature, air delivery mode, fan
speed, and air conditioning for best comfort in the
vehicle.To activate the automatic system:
AUTO (Automatic Mode):
1. Turn the fan and mode controls to the AUTO
position. This also sets the recirculation mode
to automatic operation on the display.
2. Press the up or down arrows to adjust the
temperature to a comfortable setting between
70°F (21°C) and 80°F (27°C).
3. Allow the system time to stabilize. This might
take several minutes in very hot or cold
weather. Then adjust the temperature, as
needed for best comfort.
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. In cold weather, the system starts at
reduced fan speeds to avoid blowing cold air
into the vehicle until warmer air is available.
The automatic system starts out blowing air at
the oor, but changes modes automatically as
the vehicle warms up to maintain the chosen
temperature setting.
The length of time needed to warm the interior
depends on the outside temperature and
the amount of time that has passed since the
vehicle was last driven.

0(Defrost):Turn the control to this position so
that most of the air is directed to the windshield
with some air going to the side window outlets.
More information on defrosting can be found later
in this section.
O(On/Off):Press this button to turn the climate
control system on or off. While off, adjusting
any button or control, except recirculation and rear
window defog turns the system back on. The air
inlets default to outside air when the climate
control system is turned off.
PASS (Passenger’s Climate Control):Press this
button to turn the passenger’s climate control
system on or off. Then press the up or down
buttons to choose the desired setting. Pressing
the button again automatically sets the passengers
temperature to the drivers setting. Turning the
passenger’s temperature display off does not turn
off the climate control system for the passenger.
Recirculation Operation
There are three options for bringing air into the
climate control system. They are controlled
by pressing the center button on the climate
control panel. The climate control display indicates
one of the following three modes:
9AUTO (Auto Air Inlet):This mode lets the
automatic climate control system choose the
best air inlet position for cooling or warming the
vehicle. To have full automatic climate control,
the fan and mode controls must be set to
the AUTO position. Generally, recirculation will
only automatically be selected on hot days.
Your vehicle may have an optional Air Quality
Sensor. To activate the air quality sensor, the
auto air inlet setting must be used. For more
information, see Air Quality Sensor found later
in this section.

If the regular brake system warning light is not on,
you still have brakes, but you do not have
anti-lock brakes. If the regular brake system
warning light is also on, you do not have anti-lock
brakes and there is a problem with your regular
brakes. SeeBrake System Warning Light on
page 204for more information.
The ABS warning light should come on briey
when you turn the ignition key to ON. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
Your vehicle has a
traction control system
warning light.
This light will come on when your traction control
system is limiting wheel spin. You may feel or
hear the system working, but this is normal.If the traction control system warning light comes
on and stays on for an extended period of
time when the system is turned on, your vehicle
needs service. SeeTraction Control System (TCS)
on page 281for more information.
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 to have it corrected.
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.
206

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 372.
Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
It can be used to see when your engine has
warmed up and to make sure your cooling system
is operating properly. If the gage pointer moves into
the shaded area, the engine coolant is too hot and
the engine coolant temperature warning light will
come on. SeeEngine Overheating on page 372for
more information.
Tire Pressure Light
If your vehicle has this
light, it will come on
briey when you turn the
ignition on.
This light will also come on when one or more of
your tires are signicantly underinated.
A CHECK TIRE PRESSURE DIC message will
accompany the light, seeDIC Warnings and
Messages on page 220
Stop and check your tires as soon as it is safe to
do so. If underinated, inate to the proper
pressure. SeeTires on page 398for more
information.

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.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
Since you cannot see as well, you may need
to slow down and keep more space between
you and other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.

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. See
Off-Road Driving on page 291for information
about driving off-road.
Keep your vehicle in good shape. Check all
uid levels and also the brakes, tires,
cooling system, and transmission. These parts
can work hard on mountain roads.
{CAUTION:
If you do not shift down, the 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 the engine assist
the brakes on a steep downhill slope.
