Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in.
If it is, turn the steering wheel left and right while
you turn the key hard. If none of this works,
then your vehicle needs service.
B (ACC/ACCESSORY):This position lets things like
the radio and the windshield wipers operate while
the engine is off.
Lengthy operation of features such as the radio in the
ACC/ACCESSORY ignition position and the ON/RUN
position may drain the battery and prevent your vehicle
from starting. Do not operate your vehicle in the
ACC/ACCESSORY ignition position for a long period
of time.
C (ON/RUN):This is the position for driving. It is the
position the ignition switch returns to after the engine
starts, and the key is released.
The battery could be drained if you leave the key in
the ACC/ACCESSORY or ON/RUN position with
the engine off. You may not be able to start your
vehicle if the battery is allowed to drain for an extended
period of time.
D (START):This position starts the engine.Key In the Ignition
Never leave your vehicle with the keys inside, as it is an
easy target for joy riders or thieves. If you leave the
key in the ignition and park your vehicle, a chime
will sound, when you open the driver’s door. Always
remember to remove your key from the ignition and take
it with you. This will lock your ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for an
extended period of time.

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 in the automatic
position.
To use it, pull the turn signal lever toward you, then
release it.
If your headlamps are in the automatic position or on
low beam, your high-beam headlamps will turn on.
They will stay on as long as you hold the lever
toward you. The high-beam indicator on the instrument
panel cluster will come on. Release the lever to
return to normal operation.
Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on it.
8(Mist):For a single wiping cycle, turn the band to
mist. Hold it there until the wipers start. Then let go.
The wipers will stop after one wipe. If you want
more wipes, hold the band on mist longer.
6(Delay):You can set the wiper speed for a long or
short delay between wipes. This can be very useful
in light rain or snow. Turn the band to choose the delay
time. The closer to the top of the lever, the shorter
the delay.
6(Low Speed):For steady wiping at low speed,
turn the band away from you to the rst solid band past
the delay settings.
1(High Speed):For high-speed wiping, turn the
band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
carefully loosen or thaw them. If your blades do
become worn or damaged, get new blades or blade
inserts.

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.
LQ(Washer Fluid):There is a paddle marked
with the windshield washer symbol at the top of
the multifunction lever. Push the paddle to spray
washer uid on the windshield. The wipers will clear
the window and then either stop or return to the
preset speed.
_(Heated Washer Fluid):If your vehicle has the
heated windshield washer uid system, it is used
to help clear ice, snow, tree sap, or bugs from your
windshield.To activate Automatic mode for de-icing, press the
heated washer button located to the left of the
steering wheel below the instrument panel brightness
control knob. Pushing the heated washer uid button
activates 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 pushing the button again prior to the
completion of 4 wash/wipe cycles.
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 3-56.

If necessary, use non-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.
Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over a
period of years. You can help to keep the paint nish
looking new by keeping your vehicle garaged or covered
whenever possible.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However, you may use chrome polish on
chrome or stainless steel trim, if necessary.
Use special care with aluminum trim. To avoid damaging
protective trim, never use auto or chrome polish,
steam or caustic soap to clean aluminum. A coating of
wax, rubbed to high polish, is recommended for all
bright metal parts.
Windshield, Backglass, and
Wiper Blades
Clean the outside of the windshield and backglass with
glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer uid or a mild
detergent. Wash the windshield thoroughly when you
clean the blades. Bugs, road grime, sap and a buildup of
vehicle wash/wax treatments may cause wiper streaking.
Replace the wiper blades if they are worn or damaged.
Wipers can be damaged by:
Extreme dusty conditions
Sand and salt
Heat and sun
Snow and ice, without proper removal
