20 km/h (12 mph) with the seat belt
unbuckled, the warning light will
flash and the buzzer will continue to

Battery Warning Light
This light comes on briefly when the
ignition is turned on, but the engine
is not running, as a check to show
the light is working. It should go out
when the engine is started.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system (such as a loose or broken
fan belt). Pull off to a safe place well
clear of traffic and contact your
dealer. Driving while this light is on
could drain the battery.
Check and Corrective Action1. Check to see if the fan belt is broken or loose.
2. If the fan belt is loose, adjust the tension.
3. If the fan belt is broken or there is no abnormality in the fan
belt, see your dealer for
service.

General Information
Your authorized dealer has trained
technicians and genuine parts to
service your vehicle properly. For
expert advice and quality service,
see your authorized dealer.
California Proposition
65 Warning
{Warning
Most motor vehicles, including
this one, as well as many of its
service parts and fluids, contain
and/or emit chemicals known to
the State of California to cause
cancer and birth defects or other
reproductive harm. Engine
exhaust, many parts and
systems, many fluids, and some
component wear by-products
contain and/or emit these
chemicals. For more information

California Perchlorate
Materials Requirements
Certain types of automotive
applications, such as airbag
initiators, seat belt pretensioners,
and lithium batteries contained in
remote keyless transmitters, may
contain perchlorate materials.
Special handling may be necessary.

Vehicle Care 269
Never mix the specified brake fluid
with fluids of another brand.
Be careful not to spill brake fluid
onto painted surfaces or to let it
come in contact with skin. If fluid is
spilled onto a painted surface or
comes in contact with skin, wash
away the fluid with water and
immediately wipe the area clean.
Brake fluid readily absorbs moisture.
Therefore, it is necessary to close
the brake fluid container tightly for
storage.
If the brake fluid level decreases
rapidly, there may be a problem in
the brake system or brake pads or
shoe linings may have worn out.
Have your vehicle inspected by the
nearest dealer immediately.Battery - North America
Working Near Battery
The batteries are located on the
outboard side of the left frame rail,
behind the cab. The batteries are in
a carrier with the cover (2) retained
by spring clips (1).
{Danger
Follow the precautions listed in
the jump starting Danger (see
"When the Battery is Discharged")(Continued)
Danger (Continued)
when working on or near the
battery. Personal injury
(particularly to eyes) or property
damage may result from battery
explosion, battery fluid or
electrical (short circuit) burns. You
and others could be seriously
injured or killed.
If the negative cable is disconnected
from the negative terminal on the
battery within 3 minutes after turning
the engine control switch to the
"LOCK" position, the engine control
module may malfunction.
Checking the Battery
Your new vehicle is equipped with
DELKOR batteries. They need no
periodic electrolyte level
maintenance. Its top is permanently
sealed (except for two small vent
holes) and has no filler caps. You
will never have to add water.

Jump Starting
Jump Starting - North
America
When the Battery is
Discharged
Use a jumper cable (sold
separately) and the battery of
another vehicle to start the engine in
the following sequence.
{Danger
Follow the precautions listed in
the jump starting instructions
when working on or near the
battery. Personal injury
(particularly to eyes) or property
damage may result from battery
explosion, battery fluid or
electrical (short circuit) burns.
If battery fluid should come in
contact with an eye, immediately
wash away using a large amount
of water and continue washing for(Continued)
Danger (Continued)
at least 5 minutes. Following this,
you should seek medical
assistance.
When using tools or other metal
objects in the vicinity of the
battery, take care to prevent them
from coming into contact with the
positive terminal. As the vehicle
itself will conduct electricity, any
such contact can result in a
short-circuit and a highly
dangerous electric shock.
A vehicle battery generates
extremely flammable hydrogen
gas. For this reason, operations
producing sparks or requiring the
usage of an open flame must
never be carried out near a
vehicle battery. Failure to observe
this precaution can result in
explosion if the hydrogen gas
ignites. Whenever wiping up
battery fluid, a damp cloth should
be used.
(Continued)
Danger (Continued)
Batteries produce explosive
gases, contain corrosive acid,
and supply levels of electrical
current high enough to cause
burns. Therefore, to reduce the
risk of personal injury when
working near a battery:
. Always shield your eyes
and avoid leaning over a
battery whenever possible.
. Do not expose a battery to
open flames or sparks.
. Do not allow battery acid to
contact eyes or skin. Flush
any contacted area with
water immediately and
thoroughly, and get
medical help.
. Follow each step in the
jump starting instructions.
Always stop the engine whenever
the battery is to be inspected. (Continued)

312 Vehicle Care
Danger (Continued)
Dilute sulfuric acid is used as the
battery fluid. Special care must be
taken to ensure that this fluid
does not come into contact with
skin, clothing, or metal surfaces.
When disconnecting the cables
from the terminals, start with the
negative terminal. When
connecting them, the negative
terminal should be
reconnected last.
You and others could be seriously
injured.
{Warning
For safety and the protection of
the vehicle, do not push-start the
vehicle.(Continued)
Warning (Continued)
Never tow the vehicle to start
because a surge forward when
the engine starts could cause a
collision with the tow vehicle.
Also, this vehicle has a 12-volt
battery, 12-volt starting system
and a negative ground electrical
system; be sure the vehicle or
equipment used to jump start your
engine is also 12-volt. Use of any
other system may damage the
vehicle's electrical components.
Under no circumstances should
the battery's positive and negative
terminals be put in contact with
one another.
When connecting the cables,
under no circumstances should
the clips be allowed to touch each
other.(Continued)
Warning (Continued)
Do not disconnect a battery
terminal with the engine running.
It could cause a breakdown in the
electrical system.
You and others could be seriously
injured.
If you notice battery fluid leaking,
have an inspection carried out
immediately by the nearest dealer.
Diesel engine vehicles have more
than one battery because of the
higher torque required to start a
diesel engine. This procedure can
be used to start a single-battery
vehicle from any of the diesel
vehicle's batteries. However, at low
temperatures, it may not be possible
to start a diesel engine from a single
battery from another vehicle. 1. Use a vehicle that has a charged battery with the same
voltage. Make sure that the
other vehicle also has a 12-volt
starting system, and that it is
