{Caution
.Using the wrong fluid can
badly damage brake
hydraulic system parts. For
example, just a few drops of
mineral-based oil, such as
engine oil, in the brake
hydraulic system can damage
brake hydraulic system parts
so badly that they will have to
be replaced. Do not let
someone put in the wrong
kind of fluid.
.If brake fluid is spilled on the
vehicle's painted surfaces,
the paint finish can be
damaged. Be careful not to
spill brake fluid on the
vehicle. If you do, wash it off
immediately.
Battery
Refer to the replacement number
shown on the original battery label
when a new battery is needed. See
Engine Compartment Overview on
page 10-6for 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
{Warning
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
not careful. See Jump Starting on
(Continued)
Warning (Continued)
page 10-79 for tips on working
around a battery without
getting hurt.
Infrequent Usage: Remove the
black, negative (−) cable from the
battery to keep the battery from
running down.
Extended Storage: Remove the
black, negative (−) cable from the
battery or use a battery trickle
charger.

When to Check Lubricant
Refer to the Maintenance Schedule
to determine how often to check the
lubricant. See Maintenance
Schedule on page 11-3.

Jump Starting
For more information about the
vehicle battery, seeBattery on
page 10-28.
If the vehicle 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.
{Warning
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.
{Caution
Ignoring these steps could result
in costly damage to the vehicle
that would not be covered by the
vehicle warranty. Trying to start
the vehicle by pushing or pulling it
will not work, and it could damage
the vehicle.
1. Check the other vehicle. It must have a 12-volt battery with a
negative ground system.
{Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting. 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 firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking brake.
{Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle

5. Check that the jumper cables donot 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
an unpainted metal part or to a
remote negative (−) terminal if
the vehicle has one. On your
van, use the unpainted radio
antenna bracket as a remote
negative (−) terminal.
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. 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. 7. 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. On your van, use the
unpainted radio antenna bracket
as a remote negative (−)
terminal.

8. Connect the other end of thenegative (−) cable to the
negative (−) terminal location on
the vehicle with the dead battery.
On your van, use the unpainted
radio antenna bracket as a
remote negative (−) terminal.
{Caution
The vehicle uses the unpainted
radio antenna bracket as a
remote negative (-) terminal.
Move the antenna coaxial cable
out of the way before clamping
the negative jumper cable to the
fixed antenna bracket. Avoid
touching the negative cable clamp
to the air conditioning line. Failure
to do either of these could
damage the vehicle. The repairs
would not be covered by the
vehicle warranty.
9. Now start the vehicle with the good battery and run the engine
for a while.
10. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it
probably needs service.
{Caution
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 the vehicle 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.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
