2005 BUICK RANDEZVOUS relay

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 and relay center. SeeEngine
Compartment Overview on page 5-12for more
information on location.Pull up on the cap 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.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers,
and fusible thermal links.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and do not have
a spare fuse, you can borrow one that has the same
amperage. Just pick a feature of your vehicle that
you can get along without – like the radio or cigarette
lighter - and use its fuse, if it is the right amperage.
Replace it as soon as you can.
There are two fuse blocks in your vehicle: the oor
console fuse block and the underhood fuse and relay
center.
Floor Console Fuse Block
The oor console fuse block is located to the left of the
glove box near the oor. Pull the door open to access
the fuse block.
