2002 BUICK RANDEZVOUS window

3-8
Heating
Turn the temperature knob to the desired interior
temperature to warm the air.
In the lower mode, outside air will be brought in and
sent through the floor outlets. The heater works best if
you keep your windows closed while using it.
The bi
-level setting is designed for use on sunny days
when the air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
For the best results, move the temperature knob to the
middle position, and then adjust it for comfort.
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35
F (2
C) or colder. You may notice
that the transaxle will shift at a higher vehicle speed
until the engine is warmed up. This is a normal
condition designed to provide heat to the passenger
compartment and defrost the windows more quickly.If your vehicle is equipped with an engine coolant heater
and you use it during cold weather, 0
F (
-18
C) or
lower, your heating system will provide heat more
quickly because the engine coolant is already warmed.
See ªEngine Coolant Heaterº in the Index.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows.
To defrost the windows quickly, press the defrost button
and set the temperature to 90
F (32
C) and select a high
fan speed.
To warm passengers while keeping the window clear,
select the defog mode with the mode button (the defog
symbol will be lit). Select the fan speed for comfort and
windshield clearing performance.

3-9 Rear Window Defogger
Manual System
Automatic SystemPress the REAR button (the indicator light will glow) to
warm the defogger grid on the rear window. The engine
must be running for the defogger grid to warm up.
The system will turn off automatically after about
10 minutes of use. If you turn it on again, the defogger
will operate for about five minutes. You can also turn
the defogger off by turning the ignition to OFF or
by pressing the button again. The indicator light will
turn off.
If your vehicle has heated outside rearview mirrors,
the outside mirrors will also defrost when you press
this button.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.
NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.

3-10 Ventilation System
Your vehicle's flow-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
is running.
Your vehicle has air outlets that allow you to adjust
the direction and amount of airflow inside the vehicle.
Push the outlet up or down to direct the airflow.
Opening and closing the louvers will also direct airflow
from side to side.Ventilation Tips

Keep the hood and front air inlet free of ice, snow
or any other obstruction (such as leaves). This will
allow the heater and defroster to work much better,
reducing the chance of fogging the inside of
your windows.

When you enter a vehicle in cold weather, select the
lower mode and set the fan to the highest setting for
a few moments before driving off. This helps clear
the intake ducts of snow and moisture, and reduces
the chance of fogging the inside of your windows.

Keep the air path under the front seats and around
the base of the center console clear of objects.
This helps air to circulate throughout your vehicle.

If the airflow seems very low when the fan is
adjusted to the highest setting, your passenger
compartment air filter may need replacement.
See ªPassenger Compartment Air Filterº in the
Index for more information.

4-24
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh
-- such as after a day's
work
-- don't plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course,
you'll find experienced and able service experts in
Buick dealerships all across North America. They'll be
ready and willing to help if you need it.Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full?
Are all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated to the
recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?

Maps: Do you have up
-to-date maps?

4-31

Tie a red cloth to your vehicle to alert police that
you've been stopped by the snow.

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.

4-32
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle
-- such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as ªdinghy towingº (towing your
vehicle with all four wheels on the ground) and ªdolly
towingº (towing your vehicle with two wheels on
the ground and two wheels up on a device known
as a ªdollyº).With the proper preparation and equipment, many
vehicles can be towed in these ways. See ªDinghy
Towingº and ªDolly Towing,º following.
Here are some important things to consider before you
do recreational vehicle towing:

What's the towing capacity of the towing
vehicle? Be sure you read the tow vehicle
manufacturer's recommendations.

How far will you tow? Some vehicles have
restrictions on how far and how long they can tow.

Do you have the proper towing equipment? See your
dealer or trailering professional for additional advice
and equipment recommendations.

Is your vehicle ready to be towed? Just as you would
prepare your vehicle for a long trip, you'll want to
make sure your vehicle is prepared to be towed. See
ªBefore Leaving on a Long Tripº in the Index.

4-41 Driving with a Trailer
CAUTION:
If you have a rear-most window open and you
pull a trailer with your vehicle, carbon monoxide
(CO) could come into your vehicle. You can't see
or smell CO. It can cause unconsciousness or
death. See ªEngine Exhaustº in the Index.
To maximize your safety when towing a trailer:

Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.

Keep the rear
-most windows closed.

If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle. Do not use
recirculation because it only recirculates
the air inside your vehicle. See ªComfort
Controlsº in the Index.
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you'll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.

5-11
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 ªOverheated
Engine Protection Operating Modeº in the Index
for information on driving to a safe place in
an emergency.
If No Steam Is Coming From Your Engine
If you get an engine 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.

Idle for long periods in traffic.

Tow a trailer.If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. If your air conditioner is on, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you're in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (D).
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, idle the engine for
three minutes while you're parked. If you still have the
warning, turn off the engine and get everyone out of
the vehicle until it cools down. Also, see ªOverheated
Engine Protection Operating Modeº listed previously in
this section.
You may decide not to lift the hood but to get service
help right away.
