It can be dangerous to drive with the trunk lid
open because carbon monoxide
(CO) gas can
come into your vehicle. You can’t see or smell
CO. It can cause unconsciousness and even death
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:
0 Make sure all windows are shut.
0 lhrn the fan on your heating or cooling
system to its highest speed with the setting
on
AUTO and the temperature between
65°F (18°C) and 85°F (29°C). That will
force outside
air into your vehicle. See
“Comfort Controls’’ in the Index.
0 If you have air outlets on or under the
instrument panel, open them all the
way.
See “Engine Exhaust” in the Index.
To use this feature,
your vehicle must be in
PARK (P). Press the trunk
release button located on the
center console next to the
radio to open the
trunk.
You can also press the trunk button on the RKE
transmitter to access the trunk compartment. Your
Catera doesn’t have
a trunk key lock cylinder.
If your Catera loses power
temporarily, you can
manually open the
trunk
using the trunk release
handle. The handle is
located on the underside
of the trunk lid on the
driver’s side.

This section tells you how to make your air system work
for you. Your comfort control system uses
ozone-friendly
R- 134a refrigerant.
You can control the heating, cooling and ventilation in
your Catera. Guidelines for using these systems are
found later
in this section.
Electronic Climate Control (ECC)

Fan Button
The button with the fan symbol adjusts the fan speed.
Press the
up arrow to increase fan speed and the down
arrow to decrease fan speed.
Driver’s Side Temperature Knob
The driver’s side TEMP/AUTO knob adjusts the air
temperature coming through the system. Turn the
TEMP/AUTO knob clockwise to increase the

The right front passenger can control the temperature
of heated air for hisher own zone, independent from
the driver’s temperature setting. The passenger’s
temperature can be set anywhere between 60
“F ( 16°C)
and
90°F (32°C).
To turn the system on, press the passenger’s side
TEMP/AUTO knob. Rotate the knob clockwise to
increase temperature and counterclockwise to decrease.
Pressing the knob again turns off the dual-zone function
and returns the system
to the one-zone function, where
the driver controls the climate.

The outside temperature is always displayed when your
vehicle's ignition is on. If the outside temperature
display begins to flash, this means that icy road
conditions are possible. Adjust your driving if needed.
The display will flash for about
30 seconds and then
remain
on steady.
Mode Button
Press this button to deliver air through the floor, middle,
side or windshield outlets. The climate control system
will stay in the selected ECC mode until the MODE
button is pressed again or until the TEMP/AUTO knob
is pressed. Press the up or down arrow to see the
available modes.
EnglisWetric Display
You can change the temperature display from English
(degrees Fahrenheit) to metric (degrees Celsius) by
pressing and holding the driver's side TEMP/AUTO
knob for approximately three seconds. Repeat the
process to change back to English from metric.
Automatic Operation
Pressing the driver's side TEMP/AUTO knob sets the
system for automatic operation. Once the system
is set,
sensors will control the air delivery mode. Air will come
from the floor, middle, side
or windshield outlets. The
fan speed will vary as the system maintains the selected
temperature setting. (All previous manually set mode
settings will change back to a fully automatic mode
when the climate control system is turned on this way.)
Be careful not to put anything over the solar sensor
located in
the middle of the instrument panel near the
windshield. This sensor
is used by the automatic system
to regulate temperature.
To find your comfort zone, start with the
75 OF (24" C j
setting and allow about 20 minutes for the system to
regulate. Adjust the temperature if necessary. If you
choose
60°F (1 6"C), the system will remain at that
maximum cooling setting and will not regulate
fan
speed. If you choose the temperature of 90°F (32°C)'
the system will remain at that maximum heating setting
and will not regulate fan speed. Choosing either
maximum setting will not cause the system to heat or
cool any faster.

Driving on steep hills or mountains is different from
driving in flat
or rolling terrain. If
you drive
regularly in steep country, or if you’re
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 fluid
levels and also the brakes, tires, cooling system and
transmission. 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.
I A CAUTION:
If you don’t shift down, your brakes could get
so hot that they wouldn’t 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.

You really should not park your vehicle, with a trailer
attached,
on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if
you ever have to park your rig on a hill, here’s
how to do it:
1. Apply the regular brakes, but do not shift into
PARK
(P).
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
5. Release the regular brakes. PARK (P) firmly and apply the parking brake.
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
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. See the Maintenance Schedule for more
on this. Things that are especially important
in trailer
operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system
and brake adjustment. Each
of these is covered in this
manual, and the Index will help you find them quickly.
If you’re trailering, it’s a good idea to review these
sections before
you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

KALTKOLD line (seam).
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump
or somewhere else in
the cooling system.
I A C A UTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and
you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine fans are running. If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
KALT/COLD line (seam), add a 50/50
mixture of clean water (preferably distilled) and
DEX-COOL@ coolant at the coolant surge tank, but be
sure the cooling system, including the coolant surge tank
pressure cap, is cool before you do it.
(See “Engine
Coolant” in the Index for more information.)
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the coolant
surge tank pressure cap
-- even a little -- they
can come out at high speed. Never turn the
cap when the cooling system, including the
coolant surge tank pressure cap, is hot. Wait
for the cooling system and coolant surge tank
pressure cap to cool
if you ever have to turn
the pressure cap.

Downloaded from www.Manualslib.com manuals search engine Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water
or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use
a 50/50 mix of clean
water and DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
