Turn Signal and Lane Change
Indicator
(CONT.)
A green 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 green 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 arrows don’t flash but just stay on,
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 green arrows
don’t go on at all when
you signal a
turn, check the fuse (see the
Index
under Fuses G Circuit Breakers) and
for burned-out bulbs.
A warning chime will remind you if you
have left your turn signal on for more
than
‘/2 mile (-8 km) of driving.
. Cruise Control (OPTION)
With cruise control, you can maintain a
speed of about
25 mph (40 lun/h) or
more without keeping your foot on the
accelerator. This can really help on long
trips.
Cruise control does not work at speeds
below about
25 mph (40 lun/h).
When you apply your brakes, the cruise
control shuts off.

Low Coolant Warning Light
If this light comes on, your system is
low on coolant and the engine may
overheat.
See the
Index under Engine Coolant
and have your vehicle serviced as soon
as you can.
Oil Warning Light
(E LE CTRONlC CLUSTER)
If you have a problem with your oil, 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 three
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.
Sometimes when the engine is idling
at a stop, the light may blink on and
off. This is normal.
If you make a hard stop, the light may
come on for a moment. This is
normal.

Your Driving and the Road
Driving with a Trailer (CONT.)
Making Turns
When you’re turning with a trailer,
make wider turns than normal.
Do this
so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or
other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has
to have
a different turn signal flasher
and extra wiring. The green arrows
on
your instrument panel will flash
whenever you signal a turn or lane
change. Properly hooked up, the trailer
lights will also flash, telling other
drivers you’re about to turn, change
lanes or stop. When towing a
trailer, the green 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.
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 lm/h) to reduce the possibility of
engine and transaxle overheating.
If you are towing a trailer and you have
an automatic transaxle with Overdrive,
you may want to drive in
D instead of
(or, as you need to, a lower gear).
