10-28 Vehicle Care
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/clutch
hydraulic system can also cause
a low fluid level. Have the brake/
clutch hydraulic system fixed,
since a leak means that sooner
or later the brakes will not
work well.
Do not top off the brake/clutch 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 fluid, as
necessary, only when work is done
on the brake/clutch 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/clutch
hydraulic system.
Checking Brake Fluid
The brake/clutch fluid can be
checked without taking off the cap
by looking at the brake/clutch fluid
reservoir.
The fluid level should be above
MIN. If it is not, have the brake/
clutch hydraulic system checked to
see if there is a leak.
After work is done on the brake/
clutch hydraulic system, make sure
the level is above MIN but not over
the MAX mark. When the brake/clutch fluid falls to a
low level, the brake warning light
comes on. See
Brake System
Warning Light on page 5‑18.
What to Add
If the vehicle has DOT 3 brake fluid,
as indicated on the reservoir cap,
use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 11‑13.
If the vehicle has DOT 4 brake fluid,
as indicated on the reservoir cap,
use only new DOT 4 brake fluid
from a sealed container. It is
recommended that the brake/clutch
hydraulic system be flushed and
refilled with new DOT 4 fluid at a
regular maintenance service every
two years. See Maintenance
Schedule on page 11‑3 and
Recommended Fluids and
Lubricants on page 11‑13.

Vehicle Care 10-29
Always clean the brake/clutch 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/clutch hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake/clutch fluid.
Notice
.Using the wrong fluid can
badly damage brake/clutch
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
This vehicle has a standard 12‐volt
battery. Refer to the replacement
number on the original battery label
when a new standard 12‐volt battery
is needed.
eAssist vehicles also have a high
voltage battery. Only a trained
service technician with the proper
knowledge and tools should inspect,
test, or replace the high voltage
battery. See your dealer if the high
voltage battery needs service. The
dealer has information on how to
recycle the high voltage battery.
There is also information available
at http://www.recyclemybattery.com.
The eAssist system high voltage
battery is cooled with air drawn from
the vehicle interior. The cold air
intake for the battery is located
behind the rear seat, on the filler
panel. Do not cover the intake.
{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. SeeJump Starting
(On-board with eAssist Only) on
page 10‑89 orJump Starting (with
or without eAssist) on page 10‑91
for tips on working around a
battery without getting hurt.
Infrequent Usage: Remove the
12‐volt battery black, negative (−)
cable from the battery to keep the
battery from running down.
Extended Storage: Remove the
12‐volt battery black, negative (−)
cable from the battery or use a
battery trickle charger.
Remember to reconnect the battery
when ready to drive the vehicle.
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 9‑34.
Do not use the accelerator
pedal, and be ready to turn off
the engine immediately if it
starts. 3. For automatic transmission
vehicles, 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.
For manual transmission
vehicles, put the shift lever in
Neutral, push the clutch pedal
down halfway, and try to start
the engine. The vehicle should
start only when the clutch pedal
is pushed down all the way to
the floor. If the vehicle starts
when the clutch pedal is not
pushed all the way down,
contact your dealer for service.

Additional
Maintenance and Care
Your vehicle is an important
investment and caring for it properly
may help to avoid future costly
repairs. To maintain vehicle
performance, additional
maintenance services may be
required. It is recommended
that your dealer perform these
services —their trained dealer
technicians know your vehicle best.
Your dealer can also perform a
thorough assessment with a
multi‐point inspection to recommend
when your vehicle may need
attention. The following list is
intended to explain the services and
conditions to look for that may
indicate services are required.
