Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
GTurn and Lane Change Signals
23Headlamp High/Low-Beam Changer
Flash-to-Pass Feature
NWindshield Wipers
JWindshield Washer
ICruise Control
Turn and Lane-Change Signals
The turn signal has two upward and two downward
positions.
To signal a turn, move the lever all the way up or down.
When the turn is nished, the lever returns automatically.
An arrow on the instrument
panel cluster ashes in the
direction of the turn or
lane change.
To signal a lane change, raise or lower the lever until
the arrow starts to ash. Hold it there until your lane
change is completed. The lever returns by itself when
released.
If the arrows ash more quickly than normal, a signal
bulb could be burned out. Replace the bulb. If the arrows
do not go on at all when you signal a turn, check the
fuse. SeeFuses and Circuit Breakers on page 5-110
and check for burned-out bulbs.
If you have a trailer towing option with added wiring for
the trailer lamps, a turn signal asher is used. With this
asher installed, the signal indicator ashes even if a turn
signal bulb is burned out. Check the front and rear turn
signal lamps regularly to make sure they are working.

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

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.
The rear window/washer
control is located to the
right of the steering wheel
on the instrument panel.To turn the rear wiper on, turn the control to either 1, 2,
or 3. For delayed wiping, turn the control to 1 or 2. For
steady wiping, turn the control to 3. To turn the wiper off,
turn the control to 0.
To wash the rear window, press the washer symbol
located in the center of the control.
The rear window washer uses the uid from the same
reservoir as the windshield washer. However, the
rear window washer runs out of uid before the
windshield washer. If you can wash your windshield
but not your rear window, check the uid level.

on the accelerator. This can really help on long
trips. Cruise control does not work at speeds below
about 25 mph (40 km/h).
If you apply the brakes, the cruise control shuts off.
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause excessive wheel slip, and
you could lose control. Do not use cruise
control on slippery roads.
{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

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.

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.
Automatic Headlamp System
When it is dark enough outside, the Automatic
Headlamp System turns on the headlamps when the
vehicle is started and after the transaxle has been
shifted out of the PARK (P) position. The headlamps,
taillamps, sidemarker, and parking lamps will come
on. The instrument panel lights and radio lights will
also turn on at normal brightness. Once on, the system
remains on during these conditions even if the vehicle
is shifted back into PARK (P).
The vehicle has a light sensor on the top of the
instrument panel. Make sure it is not covered or the
system may come on whenever the ignition is on and
the vehicle is shifted out of the PARK (P) position.
The system could also turn on the lamps when driving
through a parking garage, heavy overcast weather
or a tunnel. This is normal.
