Instruments and Controls 9710 minutes of turning off the vehicle.
See Retained Accessory Power
(RAP) 0 148 .
CautionLeaving electrical equipment
plugged in for an extended period
of time while the vehicle is off will
drain the battery. Always unplug
electrical equipment when not in
use and do not plug in equipment
that exceeds the maximum
20 amp rating.
Certain electrical accessories may
not be compatible with the
accessory power outlet and could
overload vehicle or adapter fuses.
If a problem is experienced, see
your dealer. When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment. See Add-On Electrical
Equipment 0 172 .
CautionHanging 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. 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.

Engine Oil 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 0 181 .
.
Always dispose of engine oil
properly. See “ What to Do with
Used Oil ” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0 178 for the location.{ WarningThe engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center
(DIC) message displays, check the
oil level.
Follow these guidelines:
.
To get an accurate reading, park
the vehicle on level ground.
Check the engine oil level after
the engine has been off for at
least two hours. Checking the
engine oil level on steep grades
or too soon after engine shutoff
can result in incorrect readings.
Accuracy improves when
checking a cold engine prior to
starting. Remove the dipstick
and check the level.
.
If unable to wait two hours, the
engine must be off for at least
15 minutes if the engine is
warm, or at least 30 minutes if

To replace one of these bulbs:
1. Push the left end of the lamp
assembly toward the right.
2. Turn the lamp assembly down
to remove it.
3. Turn the bulb socket (1)
counterclockwise to remove it
from the lamp assembly (3).
4. Pull the bulb (2) straight out of
the bulb socket (1).
5. Push the replacement bulb
straight into the bulb socket
and turn the bulb socket
clockwise to install it into the
lamp assembly.
6. Turn the lamp assembly into
the lamp assembly opening by
engaging the clip side first.
7. Push on the lamp side opposite
the clip until the lamp assembly
snaps into place.Electrical System Electrical System
Overload The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
power devices in the vehicle.
Replace a bad fuse with a new one
of the identical size and rating.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
