Vehicle Care 10-25Replacing 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. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front and
rear brakes — for the worse. The
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed. Brake Fluid
The brake master cylinder reservoir
is filled with DOT 3 brake fluid. See
Engine Compartment Overview on
page 10 ‑ 6 for the location of the
reservoir.
There are only two reasons why the
brake fluid level in the reservoir
might go down: .
The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up. .
A fluid leak in the brake
hydraulic system can also cause
a low fluid level. Have the brake
hydraulic system fixed, since a
leak means that sooner or later
the brakes will not work well. Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
{ WARNINGIf too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake hydraulic
system. See “ Checking Brake
Fluid ” in this section.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light on page 5 ‑ 19 .

10-26 Vehicle Care Refer to the Maintenance Schedule
to determine when to check the
brake fluid. See Maintenance
Schedule on page 11 ‑ 3 .
Checking Brake Fluid Check brake fluid by looking at the
brake fluid reservoir. See Engine
Compartment Overview on
page 10 ‑ 6 .
The fluid level should be above
MIN. If it is not, have the brake
hydraulic system checked to see if
there is a leak. After work is done on the brake
hydraulic system, make sure the
level is above the MIN but not over
the MAX mark.
What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 11 ‑ 13 .
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering the
reservoir.
{ WARNING
With the wrong kind of fluid in the
brake hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake fluid. Notice .
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 If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Refer to the replacement number on
the original battery label when a
new battery is needed. See Engine
Compartment Overview on
page 10 ‑ 6 for battery location.
{ WARNINGBattery 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
{ WARNINGBatteries 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
page 10 ‑ 88 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. All-Wheel Drive Transfer Case If the vehicle is equipped with
All-Wheel Drive, be sure to perform
the lubricant checks described in
this section.
When to Check Lubricant
Refer to Maintenance Schedule on
page 11 ‑ 3 to determine how often to
check the lubricant.

Lubricants on page 11 ‑ 13 to
determine what kind of lubricant
to use.
Starter Switch Check
{ WARNINGWhen you are doing this
inspection, the vehicle could
move suddenly. If the vehicle
moves, you or others could be
injured.
1. Before starting this check, be
sure there is enough room
around the vehicle.
2. Firmly apply both the parking
brake and the regular brake.
See Parking Brake on
page 9 ‑ 36 . Do not use the accelerator
pedal, and be ready to turn off
the engine immediately if it
starts.
3. Try to start the engine in each
gear. The vehicle should start
only in P (Park) or N (Neutral).
If the vehicle starts in any other
position, contact your dealer for
service.

sure there is enough room
around the vehicle. It should be
parked on a level surface.
2. Firmly apply the parking brake.
See Parking Brake on
page 9 ‑ 36 .
Be ready to apply the regular
brake immediately if the vehicle
begins to move.
3. With the engine off, turn the
ignition on, but do not start the
engine. Without applying the
regular brake, try to move the
shift lever out of P (Park) with
normal effort. If the shift lever
moves out of P (Park), contact
your dealer for service.

Ignition Transmission
Lock Check While parked, and with the parking
brake set, try to turn the ignition to
LOCK/OFF in each shift lever
position. .
The ignition should turn to
LOCK/OFF only when the shift
lever is in P (Park). .
The ignition key should come
out only in LOCK/OFF.
Contact your dealer if service is
required. Park Brake and P (Park)
Mechanism Check
{ WARNINGWhen you are doing this check,
the vehicle could begin to move.
You or others could be injured
and property could be damaged.
Make sure there is room in front
of the vehicle in case it begins to
roll. Be ready to apply the regular
brake at once should the vehicle
begin to move. Park on a fairly steep hill, with the
vehicle facing downhill. Keeping
your foot on the regular brake, set
the parking brake. .
To check the parking brake's
holding ability: With the engine
running and the transmission in
N (Neutral), slowly remove foot
pressure from the regular brake
pedal. Do this until the vehicle is
held by the parking brake only. .
To check the P (Park)
mechanism's holding
ability: With the engine running,
shift to P (Park). Then release
the parking brake followed by
the regular brake.
Contact your dealer if service is
required.

10-90 Vehicle Care
The remote negative ( − ) terminal
is a stud located on the right
front of the engine, where the
negative battery cable attaches.
See Engine Compartment
Overview on page 10 ‑ 6 for more
information on the location of the
remote positive (+) and remote
negative ( − ) terminals. { WARNINGAn 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.
{ WARNINGUsing an open flame near a
battery can cause battery gas to
explode. People have been hurt
doing this, and some have been
blinded. Use a flashlight 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 filler caps, be sure the right
amount of fluid is there. If it is low,
(Continued) WARNING (Continued) add water to take care of that
first. If you do not, explosive gas
could be present.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.
{ WARNING
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.
