Charging system:Illuminates when
the battery is not charging properly.
Wait to start:Indicates the air
intake heater is in operation and
special starting procedures are
required. Refer to theDriving
chapter.
If equipped with an air intake heater, DO NOT use ether or any
other starting fluids. The use of starting fluids (ether) in an
engine equipped with an air intake heater could result in damage
and/or personal injury.
Water in fuel (if equipped):
During refueling it is possible for
water-contaminated diesel fuel to be
pumped into your fuel tank. Your
vehicle fuel system is equipped with
a fuel filter/water separator to remove water from the fuel. The indicator
light illuminates when the fuel filter/water separator has a significant
quantity of water, or when the ignition key is switched to the START
position. If the light illuminates when the engine is running, stop the
vehicle as soon as safely possible, shut off the engine and drain the filter
bowl. Allowing water to stay in the system could result in extensive
damage to, or failure of, the fuel injection system.
To drain the fuel filter/water separator (refer toMaintenance and
Specificationschapter for procedure), rotate the valve at the bottom of
the filter assembly allowing water to drain from the system. Close the
valve upon completion.
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.

Tachometer:Indicates the engine
speed in revolutions per minute.
Driving with your tachometer
pointer continuously at the top of
the scale may damage the engine.
Battery voltage gauge:Indicates
the battery voltage when the
ignition is in the ON position. If the
pointer moves and stays outside the
normal operating range (as
indicated by arrows), have the
vehicle’s electrical system checked
as soon as possible.
Engine oil pressure gauge:
Indicates engine oil pressure. The
needle should stay in the normal
operating range (as indicated by the
arrows). If the needle falls below
the normal range, stop the vehicle,
turn off the engine and check the
engine oil level. Add oil if needed. If
the oil level is correct, have your
vehicle checked at your dealership
or by a qualified technician.
Air filter restriction gauge:
Measures the vacuum inside the air
cleaner. The more the air cleaner is
restricted (dirty, clogged), the
higher the vacuum reading. Change
the air filter when the gauge reads
25 inches. After installation of the
new filter element, reset the gauge
to 0.

HAZARD FLASHER
The hazard flasher control is located
on the steering column, just behind
the steering wheel. The hazard
flashers will operate when the
ignition is off.
Push in the flasher control and all
front and rear direction signals will
flash. Press the flasher control again
to turn them off. Use it when your
vehicle is disabled and is creating a
safety hazard for other motorists.
Note:With extended use, the flasher may run down your battery.
FUSING
If electrical components in the vehicle are not working, a fuse may have
blown. Blown fuses are identified by a broken wire within the fuse.
Check the appropriate fuses before replacing any electrical components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; doing so may
damage the catalytic converter.
Jump starting your vehicle
The gases around the battery can explode if exposed to flames,

2. Connect the other end of the positive (+) cable to the positive (+)
terminal of the assisting battery.
3. Connect the negative (-) cable to the negative (-) terminal of the
assisting battery.
4. Make the final connection of the negative (-) cable to an exposed
metal part of the stalled vehicle’s engine, away from the battery and the
carburetor/fuel injection system.Do notuse fuel lines, engine rocker
covers or the intake manifold asgroundingpoints.
Do not connect the end of the second cable to the negative (-)
terminal of the battery to be jumped. A spark may cause an
explosion of the gases that surround the battery.
5. Ensure that the cables are clear of fan blades, belts, moving parts of
both engines, or any fuel delivery system parts.
