9-24 Vehicle Care
Brake Fluid
The brake master cylinder reservoir
is filled with DOT 3 brake fluid as
indicated on the reservoir cap. See
Engine Compartment Overview
on
page 9‑6for 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.
{WARNING
If 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. When the brake fluid falls to a low
level, the brake warning light comes
on. See
Brake System Warning
Light on page 4‑19.
What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 10‑7.
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.

Vehicle Care 9-25
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
Refer to the replacement number on
the original battery label when a
new battery is needed.
{DANGER
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
page 9‑78
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
When to Check and Change
Lubricant
Refer to the Maintenance Schedule
to determine how often to check the
lubricant and when to change it.
SeeScheduled Maintenance
on
page 10‑2.
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface. If the level is below the bottom of
the filler plug hole, located on the
transfer case, you will need to add
some lubricant. Add enough
lubricant to raise the level to the
bottom of the filler plug hole. A fluid
loss could indicate a problem; check
and have it repaired, if needed.
What to Use
Refer to the Maintenance Schedule
to determine what kind of lubricant
to use. See
Recommended Fluids
and Lubricants on page 10‑7.
Starter Switch Check
{WARNING
When 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 8‑40.
Do not use the accelerator
pedal, and be ready to turn off
the engine immediately if it
starts.

Vehicle Care 9-83
4. Turn all accessories off.
5. To prevent the battery fromdraining while the vehicle is
being towed, remove fuse 32,
the Discrete Logic Ignition
Switch fuse, from the instrument
panel fuse block and store it in a
safe location. See Instrument
Panel Fuse Block on page 9‑42.
Notice: If the vehicle is towed
without performing each of the
steps listed under “Dinghy
Towing,” the automatic
transmission could be damaged.
Be sure to follow all steps of the
dinghy towing procedure prior to
and after towing the vehicle.
Notice: If 105 km/h (65 mph) is
exceeded while towing the
vehicle, it could be damaged.
Never exceed 105 km/h (65 mph)
while towing the vehicle. Once the destination has been
reached:
1. Set the parking brake.
2. Shift the transmission to
P (Park).
3. Turn the ignition key to LOCK/OFF.
4. Install fuse 32, the Discrete Logic Ignition Switch fuse. See
Instrument Panel Fuse Block
on
page 9‑42.
5. Start the engine and let it idle for more than three minutes before
driving the vehicle.
Notice: Too much or too
little fluid can damage the
transmission. Be sure that the
transmission fluid is at the proper
level before towing with all four
wheels on the ground. Notice:
Do not tow a vehicle with
the front drive wheels on the
ground if one of the front tires is
a compact spare tire. Towing with
two different tire sizes on the
front of the vehicle can cause
severe damage to the
transmission.
Dolly Towing
(All-Wheel‐Drive Vehicles)
All-wheel‐drive vehicles should not
be towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off of the ground or dinghy towed
from the front.

Service and Maintenance 10-3
system is reset accidentally,
service the vehicle within
5 000 km/3,000 miles since the
last service. Reset the oil life
system whenever the oil is changed.
SeeEngine Oil Life System
on
page 9‑12.
When the Change Engine Oil Soon
message displays, certain services,
checks, and inspections are
required. The services described for
Maintenance Ishould be performed
at every engine oil change. The
services described for Maintenance
II should be performed when:
.Maintenance Iwas performed
the last time the engine oil was
changed.
.It has been 10 months or more
since the Change Engine Oil
Soon message has displayed or
since the last service.
Maintenance I
.Change engine oil and filter. See
Engine Oilon page 9‑10.An
Emission Control Service.
.Engine coolant level check. See
Engine Coolant on page 9‑16.
.Windshield washer fluid level
check. See Washer Fluidon
page 9‑22.
.Tire inflation check. See Tire
Pressure on page 9‑52.
.Tire wear inspection. See Tire
Inspection on page 9‑58.
.Rotate tires. See Tire Rotationon page 9‑58.
.Fluids visual leak check (or
every 12 months, whichever
occurs first). A leak in any
system must be repaired and the
fluid level checked.
.Engine air cleaner filter
inspection (vehicles driven in
dusty conditions only). See
Engine Air Cleaner/Filter
on
page 9‑13.
.Brake system inspection (or
every 12 months, whichever
occurs first).
Maintenance II
.Perform all services described in
MaintenanceI.
.Steering and suspension
inspection. Visual inspection for
damaged, loose, or missing
parts or signs of wear.
.Engine cooling system
inspection. Visual inspection of
hoses, pipes, fittings, and
clamps and replacement,
if needed.

10-4 Service and Maintenance
.Windshield wiper blade
inspection for wear, cracking,
or contamination and windshield
and wiper blade cleaning,
if contaminated. SeeExterior
Care
on page 9‑85. Worn or
damaged wiper blade
replacement. See Wiper Blade
Replacement on page 9‑28.
.Body hinges and latches, key
lock cylinders, folding seat
hardware, and sunroof (if
equipped) lubrication. See
Recommended Fluids and
Lubricants

environment. Applying silicone
grease on weatherstrips with a
clean cloth makes them last
longer, seal better, and not stick
or squeak.
