2008 PONTIAC G8 trunk

If you put things inside the
vehicle — like suitcases,
tools, packages, or anything
else — they will go as fast as the
vehicle goes. If you have to
stop or turn quickly, or if there is
a crash, they will keep going.
{CAUTION
Things you put inside the
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
Put things in the trunk of
your vehicle. In a trunk,
put them as far forward as
you can. Try to spread the
weight evenly.
(Continued)
CAUTION (Continued)
Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
Do not leave an unsecured
child restraint in the
vehicle.
When you carry something
inside the vehicle, secure it
whenever you can.
Do not leave a seat folded
down unless you need to.
Fuel
Use of the recommended fuel is
an important part of the proper
maintenance of your vehicle.
To help keep the engine clean
and maintain optimum vehicle
performance, we recommend the
use of gasoline advertised as
TOP TIER Detergent Gasoline.

Replacing Brake System Parts
The braking system on a vehicle
is complex. Its many parts have to
be of top quality and work well
together if the vehicle is to have
really good braking. Your vehicle
was designed and tested with
top-quality brake parts. When you
replace parts of the braking
system — for example, when the
brake linings wear down and
you need new ones put in — be
sure you get new approved
replacement parts. If you do not, the
brakes might not work properly.
For example, if someone puts
in brake linings that are wrong for
your vehicle, the balance between
the front and rear brakes can
change — for the worse. The
braking performance you have come
to expect can change in many
other ways if someone puts in the
wrong replacement brake parts.
Battery
Your vehicle has a maintenance
free battery. When it is time
for a new battery, see your
dealer/retailer for one that has the
replacement number shown on
the original battery’s label.
The battery is located in the trunk
behind a trim panel on the
driver’s side.
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
{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 9-80for tips
on working around a battery
without getting hurt.
Infrequent Usage: If you drive your
vehicle infrequently, remove the
black, negative (−) cable from
the battery. This will help keep the
battery from running down.
Extended Storage: For extended
storage of your vehicle, remove the
black, negative (−) cable from
the battery or use a battery trickle
charger. This will help maintain
the charge of the battery over an
extended period of time.
