Instruments and Controls 71
The 110/120 volt power outlet is on the
instrument panel.
An indicator light on the outlet turns on to
show it is in use. The light comes on when
the ignition is on, 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 off, or if the equipment is not
fully seated into the outlet.
If equipment is connected using more than
150 watts or a system fault is detected, 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 Retained Accessory Power
(RAP) off and then back on. SeeRetained
Accessory Power (RAP) 0133.
The power outlet is not designed for the
following, and may not work properly if
they are 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
and touch sensor lamps
.Medical equipment
Cigarette Lighter
If equipped with a cigarette lighter, to heat,
push it in all the way and let go. When it is
ready for use, it will pop back out by itself.
Do not use the lighter to plug in accessory
devices. Use the power outlets provided.
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.
Ashtrays
If equipped with a removable ashtray, it can
be placed into the front floor console
cupholder. Open the cover to use.
Caution
If papers, pins, or other flammable items

them and possibly damage the 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.

Caution
Lack of proper engine oil maintenance
can damage the engine. Driving with the
engine oil low can also damage the
engine. The repairs would not be covered
by the vehicle warranty. Check the oil
level as soon as possible. Add oil if
required, but if the oil level is within the
operating range and the oil pressure is
still low, have the vehicle serviced.
Always follow the maintenance schedule
for changing engine oil.
Engine Coolant Temperature
Gauge
Metric
EnglishThis gauge shows the engine coolant
temperature.
It also provides an indicator of how hard the
vehicle is working. During a majority of the
operation, the gauge will read 100 °C (210 °F)
or less. If the vehicle is pulling a load or
going up hills, it is normal for the
temperature to fluctuate and approach the
122 °C (250 °F) mark. If the gauge reaches
the 125 °C (260 °F) mark, it indicates that the
cooling system is working beyond its
capacity.

{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 loss
of steering assist. Always have the engine
running and the vehicle in gear.
.Drive at speeds that keep the vehicle in
its own lane. Do not swing wide or cross
the center line.
.Be alert on top of hills; something could
be in your lane (e.g., stalled car, crash).
.Pay attention to special road signs (e.g.,
falling rocks area, winding roads, long
grades, passing or no-passing zones) and
take appropriate action.
Winter Driving
Driving on Snow or IceCaution
To avoid damage to the wheels and
brake components, always clear snow and
ice from inside the wheels and
underneath the vehicle before driving.
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on Traction Control. See Traction
Control/Electronic Stability Control 0142.
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0141.
.Allow greater following distance and
watch for slippery spots. Icy patches can
occur on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid sudden
steering maneuvers and braking while
on ice.
.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and signal
for help. Stay with the vehicle unless there
is help nearby. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning flashers.
.Tie a red cloth to an outside mirror.
{Warning
Snow can trap engine exhaust under the
vehicle. This may cause exhaust gases to
get inside. Engine exhaust contains
carbon monoxide (CO), which cannot be
seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in snow:

Warning (Continued)
personal injury may result. Always park
the vehicle in a clear open area away
from buildings or structures.
The engine coolant heater can provide easier
starting and better fuel economy during
engine warm-up in cold weather conditions
at or below −18 °C (0 °F). Vehicles with an
engine coolant heater should be plugged in
at least four hours before starting.
An internal thermostat in the plug end of
the cord may exist which will prevent
engine coolant heater operation at
temperatures above −18 °C (0 °F).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The cord for the engine coolant heater is
on the driver side of the engine
compartment.
Check the heater cord for damage. If it is
damaged, do not use it. See your dealer
for a replacement. Inspect the cord for
damage yearly.
3. Plug it into a normal, grounded 110-volt AC outlet.
{Warning
Improper use of the heater cord or an
extension cord can damage the cord and
may result in overheating and fire.
.Plug the cord into a three-prong
electrical utility receptacle that is
protected by a ground fault detection
function. An ungrounded outlet could
cause an electric shock.
.Use a weatherproof, heavy-duty,
15 amp-rated extension cord if needed.
Failure to use the recommended
extension cord in good operating
condition, or using a damaged heater
or extension cord, could make it
overheat and cause a fire, property
damage, electric shock, and injury.
.Do not operate the vehicle with the
heater cord permanently attached to
the vehicle. Possible heater cord and
thermostat damage could occur.
.While in use, do not let the heater
cord touch vehicle parts or sharp
edges. Never close the hood on the
heater cord.
