2006 CADILLAC SRX open hood

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. For
the 3.6L V6 engines, the cord is located in the
engine compartment on the passenger’s side
of the vehicle in front of the fuse block. For the
4.6L V8 engine, remove the engine compartment
cover and the cord is located on the driver’s side of
the vehicle above the strut.
You must remove the plastic cap to access
the plug.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

k(Open):Turn the thumbwheel to this symbol to open
the outlets completely and allow the maximum amount
of air to enter your vehicle. A small amount of air will still
be directed to the side windows.
l(Closed):Turn the thumbwheel to this symbol to
close the outlets and minimize the amount of air entering
the vehicle.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-33.
Rear Air Conditioning System
If your vehicle has the rear air conditioning system it
has two fan speed selectors. One fan speed selector is
located in the front overhead console and the other
is located in the headliner above the second row seats.
The rear air conditioning system is designed to
provide cooled air only.
To operate the rear system using the front control, just
turn the knob to the fan position you want.
To use the rear control, rst turn the front control to
AUX, then the rear control can be used to increase and
decrease the airow.Front Control

Passenger Compartment Air Filter
The passenger compartment air lter traps most of the
pollen from the air entering your vehicle. Like your
vehicle’s engine air cleaner/lter, it needs to be changed
periodically. For how often to change the passenger
compartment air lter, seeScheduled Maintenance on
page 6-4.
The passenger compartment air lter is located
underneath the hood below the windshield wiper arm
on the passenger’s side of the vehicle. SeeEngine
Compartment Overview on page 5-12for more
information on location.
Use the procedure listed below to replace the passenger
compartment air lter:
1. Open the hood to access the engine compartment.
SeeHood Release on page 5-11for more
information. Locate the passenger compartment
air lter access panel door.2. Push the two tabs on the access panel door
towards the windshield.
3. While pressing forward, lift the access panel out of
the clipped position and pull towards the front of the
vehicle. This releases the clips and allows the
panel door to be removed.
4. Remove the old lter and insert a new one. Make
sure the arrow on the lter is pointing toward the
passenger compartment.
SeeNormal Maintenance Replacement Parts on
page 6-14for the correct part number for the lter.
5. Reverse Steps 1 through 3 to reinstall the cover.

Gasoline Specications
At a minimum, gasoline should meet ASTM
specication D 4814 in the United States or
CAN/CGSB-3.5 in Canada. Some gasolines may
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT).
General Motors recommends against the use of
gasolines containing MMT. SeeAdditives on page 5-6
for additional information.
California Fuel
If your vehicle is certied to meet California Emissions
Standards, it is designed to operate on fuels that
meet California specications. See the underhood
emission control label. If this fuel is not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting
federal specications, but emission control system
performance may be affected. The malfunction indicator
lamp may turn on and your vehicle may fail a
smog-check test. SeeMalfunction Indicator Lamp on
page 3-43. If this occurs, return to your authorized
GM dealer for diagnosis. If it is determined that
the condition is caused by the type of fuel used, repairs
may not be covered by your warranty.
Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent engine and fuel system deposits from forming,
allowing your emission control system to work
properly. In most cases, you should not have to add
anything to your fuel. However, some gasolines contain
only the minimum amount of additive required to
meet U.S. Environmental Protection Agency regulations.
To help keep fuel injectors and intake valves clean,
or if your vehicle experiences problems due to
dirty injectors or valves, look for gasoline that is
advertised as TOP TIER Detergent Gasoline. Also, your
GM dealer has additives that will help correct and
prevent most deposit-related problems.
Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines may be available in
your area. General Motors recommends that you use
these gasolines if they comply with the specications
described earlier. However, E85 (85% ethanol)
and other fuels containing more than 10% ethanol must
not be used in vehicles that were not designed for
those fuels.

Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it is in
your vehicle. Static electricity discharge from
the container can ignite the gasoline vapor.
You can be badly burned and your vehicle
damaged if this occurs. To help avoid injury to
you and others:
Dispense gasoline only into approved
containers.
Do not ll a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed, or
on any surface other than the ground.
Bring the ll nozzle in contact with the
inside of the ll opening before operating
the nozzle. Contact should be maintained
until the lling is complete.
Do not smoke while pumping gasoline.
Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing, and tools away
from any underhood electric fan.
{CAUTION:
Things that burn can get on hot engine parts
and start a re. These include liquids like fuel,
oil, coolant, brake uid, windshield washer and
other uids, and plastic or rubber. You or
others could be burned. Be careful not to drop
or spill things that will burn onto a hot engine.
