5-6 Instruments and Controls
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. SeeRetained
Accessory Power (RAP) on
page 9-24. 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.
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.

Engine Coolant
Temperature Warning
Light
This light comes on briefly while
starting the vehicle.
If it does not, have the vehicle
serviced by the dealer. If the system
is working normally the indicator
light goes off.
{Caution
The engine coolant temperature
warning light indicates that the

with this light on can damage the
engine and it may not be covered
by the vehicle warranty. See
Engine Overheating on
page 10-22.
The engine coolant temperature
warning light comes on when the
engine has overheated.
If this happens, pull over and turn
off the engine as soon as possible.
See Engine Overheating on
page 10-22.
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A Driver Information Center (DIC)
tire pressure message may also
display. See Tire Messages on
page 5-46. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the Tire
and Loading Information label. See
Tire Pressure on page 10-48.

pressure levels occur. Stop the
vehicle as soon as safely possible
and do not operate it until the cause
of the low oil pressure has been
corrected. Check the oil as soon as
possible and have the vehicle
serviced by your dealer.
Engine Power Messages

9-8 Driving and Operating
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and(Continued)
Warning (Continued)
loss of steering. Always have the
engine running and the vehicle
in gear.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
.Be alert on top of hills;
something could be in your lane
(stalled car, accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip. Wet ice can occur at about 0°C (32°
F) when freezing rain begins to fall,
resulting in even less traction. Avoid
driving on wet ice or in freezing rain
until roads can be treated with salt
or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.
Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
Traction Control should be turned
on. See
Traction Control/Electronic
Stability Control on page 9-36.
The Antilock Brake System (ABS)
improves vehicle stability during
hard stops on slippery roads, but
apply the brakes sooner than when
on dry pavement. See Antilock
Brake System (ABS) on page 9-32.
