Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is
complete. If you momentarily press and release the
lever, the turn signal will ash 3 times.
An arrow on the instrument
panel cluster and in the
outside rearview mirror will
ash in the direction of
the turn or lane change.
Raise or lower the lever until the arrow starts to ash
to signal a lane change. Hold it there until the lane
change is complete. The lever returns when it is released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON after driving about a mile to remind
you to turn it off.
Arrows that ash rapidly when signaling for a turn or
lane change may be caused by a burned out signal bulb.
Other drivers will not see the turn signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs if
the arrow fails to work when signaling a turn. SeeRear
Underseat Fuse Block on page 5-96.

Windshield Washer
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
J(Washer Fluid):Press and release this paddle,
located at the top of the turn signal/multifunction lever,
to spray washer uid on the windshield. The wipers
will clear the windshield and either stop or return to your
preset speed. For more washer cycles, press and
hold the paddle.
_(Heated Washer Fluid):If your vehicle is equipped,
the heated windshield washer uid system may be
used to help clear ice, snow, tree sap, or bugs from
your windshield. Sliding the switch on the turn signal/
multifunction lever to this position and then releasing
it will activate the heated windshield washer uid system.
This activation will initiate four heated wash/wipe cycles.
The rst heated wash/wipe cycle may take up to
40 seconds to occur, depending on outside temperature.
After the rst wash/wipe cycle, it may take up to
20 seconds for each of the remaining cycles. The heated
windshield washer uid system may be turned off at any
time by sliding the switch on the turn signal/multifunction
lever to this position again.
When the heated windshield washer uid system is
activated under certain outside temperature conditions,
steam may ow out of the washer nozzles for a short
period of time before washer uid is sprayed. This is a
normal condition.
A message will be displayed on the Driver Information
Center (DIC) when the washer uid is low. SeeDIC
Warnings and Messages on page 3-76.

Once you are moving on the freeway, make certain you
allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit, do
not, under any circumstances, stop and back up. Drive
on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted. Reduce your speed
according to your speedometer, not to your sense
of motion. After driving for any distance at higher
speeds, you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
rst part of the journey. Wear comfortable clothing
and shoes you can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course,
you will nd experienced and able service experts in
GM dealerships all across North America. They will be
ready and willing to help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
Lamps:Are they all working? Are the lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inated to the
recommended pressure?
Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps:Do you have up-to-date maps?

If the ENGINE OIL LOW ADD OIL message appears
on the Driver Information Center (DIC), it means
you need to check your engine oil level right away. See
“ENGINE OIL LOW ADD OIL” underDIC Warnings
and Messages on page 3-76.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
