Daytime Running Lamps/
Automatic Headlamp Control
Daytime Running Lamps are an additional safety feature that makes it easier
for others to see your vehicle during the
day. The headlamp system works automatically to help provide the right
amount of lighting at all times of the day
or night. You can still turn your headlamps on manually whenever you wish.
See Section 3 of your Owner Manual.
Turn Signal/Multifunction Lever
The Turn Signal/Multifunction Lever
located on the left side of the steering
column controls these features:
• Turn and Lane-Change Signals
• Headlamp High/Low Beam Changer
• Flash-to-Pass
• Windshield Wipers
• Windshield Washers
• Cruise Control
Delayed Headlamp Illumination
If the Automatic Headlamp Control system turns on your headlamps, they will
stay on for 90 seconds after you turn off
the ignition. Delayed Headlamp
Illumination provides lighting when exiting your car and the lamps shut off automatically. This feature can be turned off
by following the instructions in your
Owner Manual.
See Section 3 of your Owner Manual.
Turn and Lane-Change Signals
The turn signal has the following positions: two upward (for right) and two
downward (for left). These positions
allow you to signal a turn or lane
change. To signal a lane change, raise
or lower the lever until the arrow starts
to flash. The lever will return by itself
when released.
To signal a turn, move the lever all the
way up or down. 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 your headlamps from low
beams to high beams, or high to low,
pull the multifunction lever all the way
toward you, then release it. When the
high beams are on, a

This feature uses the vehicle’s high
beams to alert the driver in front of you
that you intend to pass. To use it, pull
the turn signal lever toward you slightly,
but not so far that you hear a click. The
high beams will remain on for as long as
you hold the lever toward you.
Windshield Wipers
To operate the windshield wipers, turn
the WIPER band located on the multifunction lever upward or downward.
To turn off the windshield wipers, turn
the band to OFF.
For low speed wiping, turn the band
away from you to the LO setting. For
high speeds, turn the band to HI.
Five sensitivity settings, located between
the OFF and HI settings, are provided
for a delayed wiping cycle.
Turn the band to the MIST setting for a
single wiping cycle. Hold the band until
the wipers begin, then let it go.
Windshield Washers
The windshield washer paddle is
marked PUSH and is located on top of
the multifunction lever. Push the paddle
to spray washer fluid onto the windshield. The wipers will run for several
sweeps, then stop or return to your preset speed.
See Section 3 of your Owner Manual.
Cruise Control
The Cruise Control feature is located at
the end of the Turn Signal/Multifunction
Lever. Cruise Control allows you to
maintain a speed of about 25 mph or

use Cruise Control:
1. Move the Cruise Control switch to ON.
2. Achieve the speed you desire.

See Section 3 of your Owner Manual.
Oil Life Monitor
The Oil Life Monitor shows an estimate
of the oil’s remaining useful life. When
the oil life index is less than 10 percent,

(if equipped)
Your vehicle is equipped with an antilock
brake system (ABS), an advanced electronic brake system that will help prevent a braking skid. When you start your
engine or begin to drive away, you may
hear a slight noise or feel a brake pedal
vibration — this is normal; the system is
simply checking itself.
Using Antilock Brakes:
• Never pump your brakes. Just hold
the brake pedal down firmly and
• You may feel a slight pedal pulsation
or notice some noise — that’s OK
— it means your ABS is working
