102 Instruments and Controls
overload vehicle or adapter fuses.
If there is a problem, see your
dealer.
When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment. SeeAdd-On Electrical
Equipment 0218.
Caution
Hanging heavy equipment from
the power outlet can cause
damage not covered by the
vehicle warranty. The power
outlets are designed for
accessory power plugs only, such
as cell phone charge cords.
Power Outlet 110/120 Volt
Alternating Current
If equipped, this power outlet is on
the rear of the center console. It can
be used to plug in electrical
equipment with a maximum limit of
150 watts.An indicator light on the outlet
comes on when in use. The light
comes on when the ignition is in
ON/RUN, equipment requiring less
than 150 watts is plugged into the
outlet, and no system fault is
detected.
The indicator light does not come on
when the ignition is in LOCK/OFF or
if the equipment is not fully seated
into the outlet.
If you try to connect equipment
using more than 150 watts or a
system fault is detected, the
equipment may operate for a short
period and turn itself off.
A protection circuit shuts off the power supply and the indicator light
turns off. To reset the circuit, unplug
the item and plug it back in or turn
the Remote Accessory Power (RAP)
off and then back on. See
Retained
Accessory Power (RAP) 0183.
Prolonged usage of the power outlet
at the maximum load of 150 watts
may cause the outlet to overheat
and automatically shut down. The
power restarts when equipment that
operates within the limit is plugged
into the outlet and a system fault is
not detected.
The power outlet is not designed for
the following equipment, and may
not work properly if any of the
following is plugged in:
. Equipment with high initial peak
wattage such as:
compressor-driven refrigerators
and electric power tools.
. Other equipment requiring an
extremely stable power supply
such as:
microcomputer-controlled
electric blankets, touch sensor
lamps, etc.
. Medical equipment.

Instruments and Controls 103
Cigarette Lighter
If equipped, push the lighter down
and it will pop up when it is ready to
be used. The ignition switch must
be in the ACC/ACCESSORY or ON/
RUN position to use the lighter.
Caution
Holding a cigarette lighter in while
it is heating does not let the
lighter back away from the
heating element when it is hot.
Damage from overheating can
occur to the lighter or heating
element, or a fuse could be
blown. Do not hold a cigarette
lighter in while it is heating.
It is not recommended to use the
cigarette lighter to plug in auxiliary
electrical equipment.
Ashtrays

vehicle. Never put flammable
items in the ashtray.
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Some warning lights come on briefly
when the engine is started to
indicate they are working. When
one of the warning lights comes on
and stays on while driving, or when
one of the gauges shows there may
be a problem, check the section that
explains what to do. Waiting to do
repairs can be costly and even
dangerous.

To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0230.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the oil must be warm and the vehicle must
be on level ground. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0
223 for the location of the engine
oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
2. Pull out the dipstick and wipe it with a clean paper towel or
cloth, then push it back in all
