2007 BUICK RANDEZVOUS Owner's Manual

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.

Jump Starting
If your vehicle’s battery has run down, you may
want to use another vehicle and some jumper
cables to start your vehicle. Be sure to use
the following steps to do it safely.
{CAUTION:
Batteries can hurt you. They can be
dangerous because:
They contain acid that can burn you.
They contain gas that can explode or
ignite.
They contain enough electricity to
burn you.
If you do not follow these steps exactly,
some or all of these things can hurt you.
Notice:Ignoring these steps could result in
costly damage to your vehicle that would
not be covered by your warranty.Trying to start your vehicle by pushing or
pulling it will not work, and it could damage
your vehicle.
1. Check the other vehicle. It must have a
12-volt battery with a negative ground system.
Notice:If the other vehicle’s system is not a
12-volt system with a negative ground, both
vehicles can be damaged. Only use vehicles
with 12-volt systems with negative grounds to
jump start your vehicle.
2. Get the vehicles close enough so the jumper
cables can reach, but be sure the vehicles are
not touching each other. If they are, it could
cause a ground connection you do not want.
You would not be able to start your vehicle, and
the bad grounding could damage the electrical
systems.
To avoid the possibility of the vehicles rolling,
set the parking brake rmly on both vehicles
involved in the jump starting procedure. Put an
automatic transaxle in PARK (P) or a manual
transaxle in NEUTRAL before setting the
parking brake.
394

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.
