2007 CHEVROLET CORVETTE battery

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 cannot 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 the exhaust pipe. And check
around again from time to time to be
sure snow does not collect there.
Open a window just a little on the side of
the vehicle that is 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.
307

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.
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.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
In order to free your vehicle when it is stuck, you
need to spin the wheels, but you do not want
to spin the wheels too fast. The method known
as rocking can help you get out when you
are stuck, but you must use caution.
{CAUTION:
If you let your vehicle’s tires spin at high
speed, they can explode, and you or others
could be injured. And, the transmission or
other parts of the vehicle can overheat.
That could cause an engine compartment
re or other damage. When you are stuck,
spin the wheels as little as possible. Do not
spin the wheels above 35 mph (55 km/h)
as shown on the speedometer.
Notice:Spinning the wheels can destroy
parts of your vehicle as well as the tires.
If you spin the wheels too fast while shifting
the transmission back and forth, you can
destroy the transmission.
For information about using tire chains on your
vehicle, seeTire Chains on page 401.

Checking Engine Oil (Except Z06)
If the CHECK OIL LEVEL message on the Driver
Information Center (DIC) comes on, check the
engine oil level right away. For more information,
seeDriver Information Center (DIC) on page 207.
You should check the engine oil level regularly;
this is an added reminder.
It is a good idea to check the engine oil level
every time you get fuel. In order to get an accurate
reading, the oil must be warm and the vehicle
must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 330
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil a few
minutes to drain back into the oil pan. If
you do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a
lint-free paper towel or a cloth, then push
it back in all the way. Remove it again,
keeping the tip down.

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, get one that
has the replacement number shown on the
original battery’s label. We recommend an
ACDelco
®replacement battery.For battery replacement, see your dealer or the
service manual. To purchase a service manual,
seeService and Owner PublicationsinService
Publications Ordering Information on page 468.
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 365for tips on working
around a battery without getting hurt.
364

Jump Starting
If your 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:If you try to start your vehicle by
pushing or pulling it, you could damage your
vehicle. Do not push or pull your vehicleto start it; instead, use the jump starting
procedure in this manual to start your vehicle
when the battery has run down.
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 start procedure. Put
an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL before
setting the parking brakes.
365

SeeEngine Compartment Overview on
page 330for the location of the engine
compartment fuse block and engine oil ll cap.
You will not need to access the battery for
jump starting. The remote terminals are
for that purpose.
{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.
CAUTION: (Continued)
CAUTION: (Continued)
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.
