Headlamp High/Low-Beam Changer
To change the headlamps from low to high
beam, push the lever toward the instrument panel.
To return to low-beam headlamps, pull the
multifunction lever toward you. Then release it.
When the high beams
are on, this indicator light
on the instrument panel
cluster will also be on.
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 the headlamps are in the automatic position or
on low beam, the high-beam headlamps turn
on. They will stay on as long as you hold the lever
toward you. The high-beam indicator on the
instrument panel cluster comes on. Release the
lever to return to normal operation.
Windshield Wipers
8(Mist):Turn the band to mist, for a single
wiping cycle. Hold it there until the wipers
start. Then let go. The wipers will stop after
one wipe. If more wipes are needed, hold the
band on mist longer.
9(Off):Move the band to off, to stop
the wipers.
173

N(Windshield Wipers):Turn the band to
control the windshield wipers.
The wiper speed can be set 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.
For steady wiping at low speed, turn the band
away from you to the rst solid band past the delay
settings. For high-speed wiping, turn the band
further, to the second solid band past the
delay settings. 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 the
blades do become worn or damaged, get new
blades or blade inserts.Windshield Washer
L(Windshield Washer):To spray washer uid
on the windshield, press the windshield washer
paddle. The wipers will clear the window and then
either stop or return to your preset speed.
{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.
Rear Window Wiper/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.

{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do
not want to. You could be startled and
even lose control. Keep the cruise control
switch off until you want to use cruise
control.
Setting Cruise Control
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press the set button at the end of the lever
and release it.
4. Take your foot off the accelerator pedal.
The accelerator pedal will not go down.Some vehicles have a
cruise light on the
instrument panel cluster
that will come on
when the cruise control
is engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired
speed and then you apply the brake. This, of
course, shuts off the cruise control. But you do not
need to reset it.
Once you are going about 25 mph (40 km/h) or
more, you can move the cruise control switch
briey from on to resume/accelerate.
You will go right back up to the previously chosen
speed and stay there.
If you hold the switch at resume/accelerate, the
vehicle keeps going faster until you release
the switch or apply the brakes. So unless you
want to go faster, do not hold the switch at
resume/accelerate.
177

Increasing Speed While Using
Cruise Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the button at the end of the
lever, then release the button and the
accelerator pedal. You will now cruise at the
higher speed.
Move the cruise switch from on to resume/
accelerate. Hold it there until you get up to the
desired speed and then release the switch. To
increase your speed in very small amounts,
move the switch briey to resume/accelerate.
Each time you do this, your vehicle will go
about 1 mph (1.6 km/h) faster.
Reducing Speed While Using
Cruise Control
Press in the set button at the end of the lever until
you reach the desired speed, then release it.
Each time you do this, you will go about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your
vehicle will slow down to the cruise control speed
set earlier.
Using Cruise Control on Hills
How well your cruise control works on hills
depends upon your speed, load and the steepness
of the hills. When going up steep hills, you may
want to step on the accelerator pedal to maintain
your speed. When going downhill, you may
have to brake or shift to a lower gear to keep your
speed down. Of course, applying the brake
takes you out of cruise control. Many drivers nd
this to be too much trouble and do not use
cruise control on steep hills.
Ending Cruise Control
There are three ways to turn off the cruise control:
Step lightly on the brake pedal.
Move the cruise switch to off, or
Shift the transmission to NEUTRAL (N).
178

Erasing Speed Memory
When you turn off the cruise control or the
ignition, the cruise control set speed memory
is erased.
Headlamps

knob is located on
your instrument panel
to the left of the
steering wheel.
c(Off):Turn the knob to this symbol and
release it to turn off the Daytime Running Lamps
(DRL) and the Automatic Headlamps (AHS).
An indicator illuminates when the position

Headlamps on Reminder
A reminder tone sounds when the headlamps or
parking lamps are manually turned on, if the
driver’s door is open and the ignition is in LOCK
or ACC. To turn the tone off, turn the knob all
the way counterclockwise.
In the automatic mode, the headlamps turn off
once the ignition key is in LOCK.
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 DRL are required on all
vehicles rst sold in Canada.The DRL system makes the headlamps come on
at reduced brightness when the following
conditions are met:
The ignition is on.
The exterior lamps knob is in automatic
headlamp mode.
The light sensor detects daytime light.
The transmission is not in PARK (P).
When the DRL are on, only the headlamps will be
on. The taillamps, sidemarker and other lamps
will not be on. The instrument panel will not be lit
up either.
When it begins to get dark, the headlamps
automatically switch from DRL to the regular
headlamps.
