2-47 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 finished, the lever will return automatically.
An arrow on the instrument
panel will flash 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 flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it.
As you signal a turn or a lane change, if the arrow
flashes faster than normal, a signal bulb may be burned
out and other drivers won't see your turn signal.If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you
signal a turn, check for burned
-out bulbs and then check
the fuse (see ªFuses and Circuit Breakersº in the Index).
A chime will sound if you leave the turn signal on for
more than 3/4 mile (1.2 km).
Headlamp High/Low Beam Changer
To change the headlamps
from low beam to high
beam, or high to low, pull
the multifunction lever all
the way toward you. Then
release it.
When the high beams are on, a light on the instrument
panel also will be on.
Flash-to-Pass Feature
When the headlamps are off, pull the lever toward you
to momentarily switch on the high beams (to signal that
you are going to pass). When you release the lever, they
will turn off.

2-78 Oil Warning Light
If you have a problem with
your oil pressure, this light
may stay on after you start
your engine, or come on
when you are driving.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have it fixed right away.
The oil light could also come on in two other situations:

When the ignition is on but the engine is not running,
the light will come on as a test to show you it is
working, but the light will go out when you turn the
ignition to START. If it doesn't come on with the
ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.

If you make a hard stop, the light may come on for a
moment. This is normal.CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

4-39 Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your dealer. The arrows on your instrument panel
will flash whenever you signal a turn or lane change.
Properly hooked up, the trailer lamps will also flash,
telling other drivers you're about to turn, change lanes
or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It's
important to check occasionally to be sure the trailer
bulbs are still working.
Your vehicle has bulb warning lights. When you plug
a trailer lighting system into your vehicle's lighting
system, its bulb warning lights may not let you know
if one of your lamps goes out. So, when you have a
trailer lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they're all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you if one
of your vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don't shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around 45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
If you have overdrive, you may want to drive in
THIRD (3), instead of DRIVE (D).
Parking on Hills
CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can
be injured, and both your vehicle and the trailer
can be damaged.
