engine BUICK RANDEZVOUS 2007 Owners Manual

Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to freeze
and damage your washer uid tank and
other parts of the washer system. Also,
water does not clean as well as washer
uid.
Fill your washer uid tank only
three-quarters full when it is very cold.
This allows for expansion if freezing
occurs, which could damage the tank
if it is completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage your
washer system and paint.
Brakes
Brake Fluid
Your brake master
cylinder reservoir
is lled with DOT-3
brake uid. SeeEngine
Compartment Overview
on page 364for the
location of the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst is that
the brake uid goes down to an acceptable level
during normal brake lining wear. When new linings
are put in, the uid level goes back up. The other
reason is that uid is leaking out of the brake
system. If it is, you should have your brake system
xed, since a leak means that sooner or later your
brakes will not work well, or will not work at all.
389

So, it is not a good idea to top off your brake uid.
Adding brake uid will not correct a leak. If you add
uid when your linings are worn, then you will have
too much uid when you get new brake linings. You
should add or remove brake uid, as necessary,
only when work is done on the brake hydraulic
system.
{CAUTION:
If your vehicle has too much brake uid, it
can spill on the engine. The uid will burn
if the engine is hot enough. You or others
could be burned, and your vehicle could
be damaged. Add brake uid only when
work is done on the brake hydraulic
system.
When your brake uid falls to a low level, your
brake warning light will come on. SeeBrake
System Warning Light on page 219.
What to Add
When you do need brake uid, use only DOT-3
brake uid. Use new brake uid from a sealed
container only. SeeRecommended Fluids
and Lubricants on page 485.
Always clean the brake uid reservoir cap and the
area around the cap before removing it. This
will help keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the brake
system, the brakes may not work well, or
they may not even work at all. This could
cause a crash. Always use the proper
brake uid.
390

Notice:
Using the wrong uid can badly damage
brake system parts. For example, just a
few drops of mineral-based oil, such
as engine oil, in the brake system can
damage brake system parts so badly that
they will have to be replaced. Do not
let someone put in the wrong kind of uid.
If you spill brake uid on your vehicle’s
painted surfaces, the paint nish can
be damaged. Be careful not to spill brake
uid on your vehicle. If you do, wash it
off immediately. SeeWashing Your Vehicle
on page 455.
Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the brake
pads are worn and new pads are needed. The
sound may come and go or be heard all the time
your vehicle is moving, except when you are
pushing on the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
Notice:Continuing to drive with worn-out
brake pads could result in costly brake repair.
Some driving conditions or climates may cause
a brake squeal when the brakes are rst applied or
lightly applied. This does not mean something is
wrong with your brakes.
391

Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. We recommend an ACDelco
®
replacement battery. SeeEngine Compartment
Overview on page 364for battery location.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm. Wash
hands after handling.
Vehicle Storage
If you are not going to drive your vehicle for 25 days
or more, remove the black, negative (−) cable from
the battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful. SeeJump
Starting on page 394for tips on working
around a battery without getting hurt.
Also, for your audio system, seeTheft-Deterrent
Feature on page 296.
393

Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty. Always
turn off your radio and other accessories when
jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the
cigarette lighter or the accessory power
outlet(s). Turn off the radios and all lamps that
are not needed. This will avoid sparks and help
save both batteries. And it could save the radio!
4. Open the hood on the other vehicle and locate
the positive (+) and negative (−) terminal
locations on that vehicle.
You will not need to access your battery for
jump starting. Your vehicle has a remote
positive (+) jump starting terminal for that
purpose. The terminal is located under a
tethered cap at the front of the underhood fuse
block. SeeEngine Compartment Overview on
page 364for more information on location.Squeeze the tabs and
swing the cap out of the
way to access the
remote positive (+)
terminal.
You should always use the remote positive (+)
terminal instead of the positive (+) terminal
on the battery.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.

{CAUTION:
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a ashlight if you need
more light.
Be sure the battery has enough water. You
do not need to add water to the battery
installed in your new vehicle. But if a
battery has ller caps, be sure the right
amount of uid is there. If it is low, add
water to take care of that rst. If you do
not, explosive gas could be present.
Battery uid contains acid that can
burn you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.
{CAUTION:
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.
5. Check that the jumper cables do not have
loose or missing insulation. If they do, you
could get a shock. The vehicles could
be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will
go to positive (+) or to a remote positive (+)
terminal if the vehicle has one. Negative (−) will
go to a heavy, unpainted metal engine part or to
a remote negative (−) terminal if the vehicle
has one.
396

Notice:If you connect a negative cable to the
engine control module (ECM), ECM mounting
bracket or any cables that attach to the
ECM bracket, you may damage the ECM.
Attach the negative cable to a heavy, unpainted
metal engine part, other than the ECM, ECM
bracket or cables attached to the ECM bracket.
Do not connect positive (+) to negative (−)or
you will get a short that would damage the
battery and maybe other parts too. And do not
connect the negative (−) cable to the
negative (−) terminal on the dead battery
because this can cause sparks.
6. Connect the red positive (+) cable to the
positive (+) terminal of the dead battery.
Use a remote positive (+) terminal if
the vehicle has one.
7. Do not let the other end touch metal. Connect
it to the positive (+) terminal of the good
battery. Use a remote positive (+) terminal if
the vehicle has one.8. Now connect the black negative (−) cable to
the negative (−) terminal of the good battery.
Use a remote negative (−) terminal if the
vehicle has one.
Do not let the other end touch anything until
the next step. The other end of the negative (−)
cable does not go to the dead battery. It
goes to a heavy, unpainted metal engine part
or to a remote negative (−) terminal on the
vehicle with the dead battery.
9. Connect the other end of the negative (−) cable
at least 18 inches (45 cm) away from the dead
battery, but not near engine parts that move.
The electrical connection is just as good there,
and the chance of sparks getting back to the
battery is much less.
10. Now start the vehicle with the good battery
and run the engine for a while.
11. Try to start the vehicle that had the dead
battery. If it will not start after a few tries, it
probably needs service.
397

Notice:If the jumper cables are connected or
removed in the wrong order, electrical shorting
may occur and damage the vehicle. The repairs
would not be covered by your warranty. Always
connect and remove the jumper cables in the
correct order, making sure that the cables do
not touch each other or other metal.
A. Heavy, Unpainted Metal Engine Part or
Remote Negative (−) Terminal
B. Good Battery or Remote Positive (+) and
Remote Negative (−) Terminals
C. Dead Battery or Remote Positive (+) TerminalTo disconnect the jumper cables from both
vehicles, do the following:
1. Disconnect the black negative (−) cable from
the vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from
the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
5. Return the remote positive (+) terminal cover
to its original position.

(B) Tire Ply Material:The type of cord and
number of plies in the sidewall and under the
tread.
(C) Tire Identication Number (TIN):The letters
and numbers following the DOT (Department of
Transportation) code is the Tire Identication
Number (TIN). The TIN shows the manufacturer
and plant code, tire size, and date the tire was
manufactured. The TIN is molded onto both sides of
the tire, although only one side may have the date
of manufacture.
(D) Maximum Cold Ination Load Limit:
Maximum load that can be carried and the
maximum pressure needed to support that load.
(E) Tire Ination:The temporary use tire or
compact spare tire should be inated to 60 psi
(420 kPa). For more information on tire pressure
and ination seeInation - Tire Pressure on
page 413.
(F) Tire Size:A combination of letters and
numbers dene a tire’s width, height, aspect ratio,
construction type, and service description. The
letter T as the rst character in the tire size means
the tire is for temporary use only.(G) TPC Spec (Tire Performance Criteria
Specication):Original equipment tires designed
to GM’s specic tire performance criteria have a
TPC specication code molded onto the sidewall.
GM’s TPC specications meet or exceed all federal
safety guidelines.
Tire Size
The following illustration shows an example of a
typical passenger vehicle tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter P
as the rst character in the tire size means a
passenger vehicle tire engineered to standards
set by the U.S. Tire and Rim Association.

To reset the system, do the following:
1. With the engine off, turn the ignition to ON.
2. Press the MODE button until the DIC reads
LOW TIRE PRESSURE HOLD SET TO
RESET.
3. Press and hold the SET button until you hear
a chime, and TIRE PRESSURE RESET is
displayed.
You will hear three chimes, then the LOW TIRE
PRESSURE message will go off and the DIC
will return to TIRE PRESSURE NORMAL. If the
LOW TIRE PRESSURE message comes back on,
the check tire pressure system has not reset.
Repeat the procedure.
The system completes the calibration process
during driving. The system learns the pressure at
each tire throughout the operating speed range
of your vehicle. The system normally takes
between 30 and 60 minutes of driving to learn
the tire pressures. The system normally takes
10 to 20 minutes of driving in each speed range
to learn tire pressures. The speed ranges are
20 to 40 mph (32 to 64 km/h), 40 to 60 mph
(64 to 96 km/h), and above 60 mph (96 km/h).
This time may be longer depending on yourindividual driving habits. The learning process
does not need to be completed during a single trip.
Once learned, the system will remember the tire
pressure until the system is reset.
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment.
Also check for damaged tires or wheels. SeeWhen
It Is Time for New Tires on page 418andWheel
Replacement on page 422for more information.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire, If it
moves, use the folding wrench to tighten the cable.
SeeStoring a Flat or Spare Tire and Tools on
page 444.
The purpose of regular rotation is to achieve
more uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 475.
