heater and defroster will work far better, reducing
the chance of fogging the inside of the windows.
of objects. This helps circulate
air throughout
your vehicle.
Keep the air path under the front seats clear
Defogging and Defrosting
On cool, humid days, use DEFOG (digital cluster

and side windows clear. Use DEFROST to remove fog or ice from the windshield quickly in extremely humid
or cold conditions.
With the digital cluster climate control panel, press
the DEFOG button and adjust the fan speed by pressing the fan button up or down.
If you use DEFROST,
adjust the fan speed the same way.
If you select
DEFROST from AUTO, the system will control the
fan speed. The temperature will also need to be
adjusted to your comfort level. Press the blue button
to decrease the temperature and the red button
to
increase the temperature. If your vehicle has a climate control panel (which
is
standard with the analog cluster). If you select

Downloaded from www.Manualslib.com manuals search engine If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want the
vehicle to go. If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid if it occurs.
If you have Stabilitrak, you may see the STABILITY
ENGAGED message on the Driver Information Center. See “Stability Engaged Message” in the Index.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you’ll
want to slow down and adjust your driving to these
conditions. It
is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting to a lower gear). Any sudden changes could cause the tires
to
slide. You may not realize the surface is slippery until
your vehicle is skidding. Learn to recognize warning
clues
-- such as enough water, ice or packed snow on
the road to make a “mirrored surface”
-- and slow down
when you have any doubt.
Remember: Any anti-lock brake system
(ABS) helps
avoid only the braking skid.
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.

You will find an ENGINE COOLANT HOT, IDLE
ENGINE message or an ENGINE
OVERHEATED
STOP, ENGINE message on the Driver Information
Center (DIC). You will
also hear a chime. There is also
an engine temperature warning light andor gage on the
instrument panel. See “Engine Coolant Temperature
Warning Light” or “Engine Coolant Temperature Gage”
in the Index.
Overheated Engine Protection
Operating Mode
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life indicator. See “Engine Oil, When to
Change” in the Index.
Should an overheated engine condition exist and the
message ENGINE OVERHEATED STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups
of four cylinders helps prevent engine
damage.
In this mode, you will notice a loss in power
and engine performance. This operating mode allows
your vehicle to be driven to a safe place in
an
emergency; you may drive up to 50 miles (80 lun).
Towing a trailer in the overheat protection mode should
be avoided.

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
If your engine catches fire because you keep driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty. See “Overheated
Engine Protection Operating Mode” in the Index.

If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Dial temperature control to the highest heat setting
and open the windows, as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- OVERDRIVE (GO) or THIRD (3).
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn’t come back on, you
can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if the warning stops. But then, if you still have the
warning,
turn off the engine and get everyone out of
the vehicle until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously in
this section.
You may decide not to lift the hood but
to get service
help right away.

Downloaded from www.Manualslib.com manuals search engine octane fuel to get rid of pinging. It's the heavy, constant
knock that means you have a problem.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate on fuels that meet
California specifications.
If such fuels are not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator lamp on your instrument panel may turn
on andor your
vehicle may
fail a smog-check test. If this occurs, return
to your authorized Cadillac dealer for diagnosis to
determine the cause of failure. In the event it is determined that the cause of the condition is the type of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT); ask your service station operator whether or not his fuel
contains MMT. General Motors does not recommend the
use .of such gasolines. If fuels containing
MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The malfunction indicator lamp on your instrument panel
may turn
on. If this occurs, return to your authorized
Cadillac dealer for service.
To provide cleaner air, all gasolines in the United States are now required to contain additives that will help
prevent deposits from forming in your engine and fuel system, allowing your emission control system to
function properly. Therefore,
you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don't use it. It can corrode
metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn't
be covered under your warranty.

Operating the engine with the air cleaner off can
cause you or others to be burned, The air cleaner
not only cleans the air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned, Don’t drive with
it
off, and be careful working on the engine with
the air cleaner
off.
NOTICE:
If the air cleaner is off, a backfke can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under
one or more of these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain. regularly reaches
90°F (32°C) or higher.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
0 Use such as limousine service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require change
until
the message CHANGE TRANS FLUID appears
on the Driver Information Center.
See “Scheduled Maintenance Services” in the
Maintenance Schedule booklet.
