Engine Coolant Heater
If your vehicle has this feature, in very cold weather,
0°F (−18°C) or colder, the engine coolant heater can
help. You will get easier starting and better fuel economy
during engine warm-up. Usually, the coolant heater
should be plugged in a minimum of four hours prior to
starting your vehicle. At temperatures above 32°F (0°C),
use of the coolant heater is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on
the passenger’s side of the vehicle, above the
headlamp assembly.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

Turn and Lane-Change Signals
The turn signal has two upward for right, and two
downward for left, positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is nished, the lever will return
automatically.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.If the arrows ash very fast as you signal a turn or a
lane change, a signal bulb may be burned out and other
drivers will not see your turn signal. If a bulb is burned
out, replace it to help avoid an accident. SeeBulb
Replacement on page 5-67.
If the arrows do not go on at all when you signal a turn,
check the fuse. SeeFuses and Circuit Breakers on
page 5-111.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each ash of the
turn signal. To turn off the chime, move the turn signal
lever to the off position.

beam, push the lever forward. To change from high
beam to low beam, pull the turn signal lever toward you,
then release it.

When the high beams are
on, this light on the
instrument panel cluster
will also be on.
If you have the SE model, both the low beam and high
beam headlamps will be on when you are in high
beam mode. If you have the SLE or GXP models, only
the high beam headlamps will be on when you are
in high beam mode.
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
It works even if your headlamps are off.
To use it, pull the turn signal lever toward you.
If your headlamps are off or on low beam, your
high-beam headlamps will turn on. They will stay on as
long as you hold the lever toward you and the
high-beam indicator on the instrument panel cluster will
come on. Release the lever to turn the high-beam
headlamps off.
Windshield Wiper Lever
The windshield wipers are controlled by the lever on the
right of your steering column.
If your windshield wipers are on for more than
six seconds while you are driving, the low-beam
headlamps, instrument panel cluster backlighting and
the taillamps will turn on. For more information see
“Wiper-Activated Headlamps” underExterior Lamps on
page 3-14.
