Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
GTurn and Lane-Change Signals. See
Turn and Lane-Change Signals on page 162.
3Headlamp High/Low-Beam Changer.
SeeHeadlamp High/Low-Beam Changer on
page 163.
Flash-To-Pass Feature. SeeFlash-to-Pass on
page 164.
NWindshield Wipers. SeeWindshield Wipers
on page 164.
LWindshield Washer. SeeWindshield
Washer on page 166.
_Heated Washer Fluid. SeeWindshield
Washer on page 166.
Turn and Lane-Change Signals
To signal a turn, move the lever on the left side of
the steering wheel all the way up or down. The lever
returns automatically when the turn is complete.
An arrow on the
instrument panel
cluster will ash in the
direction of the turn or
lane change.
You may also have an arrow in the outside mirror
that ashes when the turn signal is used. See
Outside Power Mirrors on page 133for more
information.
162

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. If you momentarily press
and release the lever, the turn signal will ash
three times.
If the arrows ash very fast as you signal a turn or a
lane change, a signal bulb may be burned out and
other drivers will not see your turn signal. If a bulb is
burned out, replace it to help avoid an accident.
If the arrows do not go on at all when you signal
a turn, check the fuse. SeeFuses and Circuit
Breakers on page 428.
Turn Signal On Chime
If your turn signal is left on for more than
0.8 miles (1.3 km), a chime will sound at each
ash of the turn signal. To turn off the chime,
move the turn signal lever to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to
high beam, push the turn signal lever away from
you. To change from high beam to low beam,
pull the turn signal lever toward you.
While the high beams
are on, this light located
on the instrument
panel cluster will
also be on.
163

Flash-to-Pass
This feature lets you use the high-beam headlamps
to signal the driver in front of you that you want to
pass. It works even if your headlamps are off.
Pull the turn signal lever toward you briey to
ash-to-pass.
If the headlamps are off or on low beam, the
high-beam headlamps will turn on. They will stay on
as long as you hold the lever toward you and the
high-beam indicator on the instrument panel cluster
will come on.
Windshield Wipers
You control the windshield wipers by turning the
band with the wiper symbol on it.
8(Mist):Turn the band to mist for a single wiping
cycle. Hold it there until the wipers start. Then let
go. The wipers stop after one wipe. For more wipe
cycles, hold the band longer on mist.
6(Delay):Turn the band to choose the delay time
between wipe cycles. The wiper speed can be set
for a long or short delay between wipes. The closer
the band is set to the top of the lever, the shorter
the delay.
6(Low Speed):Turn the band away from
you to the rst solid band past the delay settings
for steady wiping at low speed.
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.
Clear ice and snow from the wiper blades before
using them. If they are frozen to the windshield,
carefully loosen or thaw them. If the blades
become worn or damaged, replace with new
blades or blade inserts.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools. Clear
away snow or ice to prevent an overload.
Your vehicle has wiper-activated headlamps. After
the windshield wipers have completed eight
wipe cycles within four minutes, the headlamps
automatically turn on. SeeWiper Activated
Headlamps on page 171for more information.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. Fully functional daytime running lamps
are required on all vehicles rst sold in Canada.
A light sensor on top of the instrument panel
monitors the exterior light level for the operation
of DRL, so be sure it is not covered.
The DRL system will make your low-beam
headlamps turn on at reduced brightness in
daylight when the following conditions are met:
The ignition is on.
The exterior lamp button for the headlamps
is off.
The automatic transaxle is not in PARK (P).When the DRL are on, only your low-beam
headlamps will be on. The parking lamps, taillamps,
sidemarker and other lamps will not be on.
When it is dark enough outside, your low-beam
headlamps will come on. The other lamps that turn
on with your headlamps will also turn on. When
it is bright enough outside, the regular lamps
will go off, and your low-beam headlamps change
to the reduced brightness of DRL.
To turn off all exterior lighting at night when you
are parked, turn the exterior lamp control to the
off position. The exterior lamps will turn back
on automatically when you move the transaxle out
of PARK (P). SeeExterior Lamps on page 170
for more information.
As with any vehicle, you should turn on the
regular headlamp system when you need it.

Electric Power Management
The vehicle has Electric Power Management
(EPM) that estimates the battery’s temperature and
state of charge. It then adjusts the voltage for
best performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC),
you may see the voltage move up or down. This
is normal. If there is a problem, an alert will
be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to produce
all the power that is needed for very high electrical
loads.A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans,
trailer loads, and loads plugged into accessory
power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It can
increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action
may be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 221.

No one can see as well at night as in the daytime.
But as we get older these differences increase.
A 50-year-old driver may require at least twice as
much light to see the same thing at night as a
20-year-old.
What you do in the daytime can also affect your
night vision. For example, if you spend the
day in bright sunshine you are wise to wear
sunglasses. Your eyes will have less trouble
adjusting to night. But if you are driving, do not
wear sunglasses at night. They may cut down on
glare from headlamps, but they also make a
lot of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or
even several seconds, for your eyes to re-adjust
to the dark. When you are faced with severe glare,
as from a driver who does not lower the high
beams, or a vehicle with misaimed headlamps,
slow down a little. Avoid staring directly into
the approaching headlamps.Keep the windshield and all the glass on your
vehicle clean — inside and out. Glare at night is
made much worse by dirt on the glass. Even
the inside of the glass can build up a lm caused
by dust. Dirty glass makes lights dazzle and
ash more than clean glass would, making the
pupils of your eyes contract repeatedly.
Remember that the headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it is easier to pick out dimly
lighted objects. Just as the headlamps should be
checked regularly for proper aim, so should your
eyes be examined regularly. Some drivers suffer
from night blindness — the inability to see in dim
light — and are not even aware of it.

To disconnect the jumper cables from both
vehicles, do the following:
1. Disconnect the black negative (−) cable from
the vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from
the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
5. Return the positive (+) remote terminal cover
to its original position.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been
preset at the factory and should need no further
adjustment.
However, if the vehicle is damaged in an accident,
the aim of the headlamps may be affected and
adjustment may be necessary.
If oncoming vehicles ash their high beams at
you, this may mean the vertical aim of your
headlamps needs to be adjusted.It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be
adjusted. It is possible however, to re-aim the
headlamps as described in the following procedure.
The vehicle should be properly prepared as
follows:
The vehicle should be placed so the
headlamps are 25 ft. (7.6 m) from a light
colored wall.
The vehicle must have all four tires on a level
surface which is level all the way to the wall.
The vehicle should be placed so it is
perpendicular to the wall.
The vehicle should not have any snow, ice or
mud on it.
The vehicle should be fully assembled and all
other work stopped while headlamp aiming is
being performed.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs
(75 kg) sitting on the driver’s seat.
Tires should be properly inated.
The spare tire is in its proper location in the
vehicle.
377

Headlamp aiming is done with the vehicle’s
low-beam headlamps. The high-beam headlamps
will be correctly aimed if the low-beam headlamps
are aimed properly.
To adjust the vertical aim, do the following:
1. Open the hood. SeeHood Release on
page 333for more information.
2. Locate the aim dot on the lens of the
low-beam headlamp.
3. Measure the distance from the ground to the
aim dot on the low-beam headlamp. Record
the distance.4. At the wall measure from the ground
upward (A) to the recorded distance
from Step 3 and mark it.
5. Draw or tape a horizontal line (B) on the wall
the width of the vehicle at the height of the
mark in Step 4.
Notice:Do not cover a headlamp to improve
beam cut-off when aiming. Covering a
headlamp may cause excessive heat build-up
which may cause damage to the headlamp.
