Turn Signal and Lane Change indicator
..

." I .. . ..,." .
K2240
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.
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 flash twice as fast as
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 green
arrows don't go on at all when you signal a turn, check the \
fuse (see
"Fuses" in the Index) and for burned-out bulbs.
Operation of Lights
Although your vehicle's lighting system (headlights, parking lig\
hts, fog lamps,
side marker lights and taillights) meet all applicable federal lighting
requirements, certain states and provinces may apply their own \
lighting
regulations that may require special attention before you operate these lights.
For example, some jurisdictions may require that you operate yo\

Your Driving and the Road
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 pan\
el 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 45 mph (70
kmlh) or less to reduce the possibility of engine and transmission overheating.
If you have an automatic transmission, you should use D (or, as you need to,
a lower gear) when towing a trailer. Operating your vehicle in D when towing
a trailer will minimize heat buildup and extend the
life of your transmission.
Or,
if you have a manual transmission with fifth gear and you are to\
wing a
trailer, it’s better not
to use fifth gear, just drive in fourth gear (or, as you
need to, a lower gear).
Parking on Hilk
You really should not park your rig 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.
But
if you ever have to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into P (Park) yet, or into gear
for a manual transmission.
2. Have someone place chocks under the trailer wheels.
3, When the wheel chocks are in place, release the regular brakes\
until the
4. Reapply the regular brakes. Then apply your parking brake, and \
then
chocks absorb the load.
shift
to P (Park), or R (Reverse) for a manual transmission.
5. If you have a four-wheel-drive vehicle, be sure the transfer case \
is in
a
drive gear-not in
N (Neutral).

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from short circuits by a
combination
of fuses, circuit breakers, and fusible thermal links in the wirin\

of fires caused by electrical problems.
See “Fuses and Circuit Breakers” in the Index for more information.

Headlights
The headlight wiring is protected by a circuit breaker
in the light switch. An
electrical overload will cause the lights
to go on and off, or in some cases to
remain
off. If this happens, have your headlight wiring checked right away.
