To tilt the wheel, hold the
wheel and pull the lever.
Then move the steering
wheel to a comfortable
position and release
the lever to lock the wheel
into place.Turn Signal/Multifunction Lever

includes the following:
·Turn and Lane-Change Signals
·Headlamp High/Low-Beam Changer
·Flash-to-Pass
·Windshield Wipers
·Windshield Washer
·Cruise Control
3-5

Windshield Washer
J
(Windshield Washer):At the top of the
multifunction lever, there is a paddle with the word
PUSH on it. To spray washer ¯uid on the windshield,
push on the paddle. The wipers will run for several
sweeps and then either stop or return to your preset
speed. See
Windshield Washer Fluid on page 5-38.
{CAUTION:
In freezing weather, don't use your washer
until the windshield is warmed. Otherwise the
washer ¯uid can form ice on the windshield,
blocking your vision.
The LOW WASH light on
your instrument panel
cluster will come on when
the ¯uid level is low.
Cruise Control
If your vehicle has cruise control, you can maintain a
speed of about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can really
help on long trips. Cruise control does not work at
speeds below about 25 mph (40 km/h).
When you apply your brakes, the cruise control shuts off.
{CAUTION:
·Cruise control can be dangerous where
you can't drive safely at a steady speed.
So, don't 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
needless wheel spinning, and you could
lose control. Don't use cruise control on
slippery roads.
3-8

If your vehicle is in cruise control when the enhanced
traction system begins to limit wheel spin, the cruise
control will automatically disengage. See
Enhanced
Traction System (ETS) on page 4-10. When road
conditions allow you to safely use it again, you may turn
the cruise control back on.
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you're
not using cruise, you might hit a button and go
into cruise when you don't want to. You could
be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Push in the SET button at the end of the lever and
release it. The CRUISE light on the instrument
panel cluster will come on.
4. Take your foot off the accelerator pedal.
3-9

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 don't need to reset it.
Once you're going about 25 mph (40 km/h) or more, you
can move the cruise control switch from ON to R/A
(Resume/Accelerate) brie¯y. You'll go right back up to
your chosen speed and stay there.
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. Push in the SET button, then release
the button and the accelerator pedal. You'll now
cruise at the higher speed.
·Move the cruise switch from ON to R/A. Hold it there
until you get up to the speed you want, and then
release the switch. (To increase your speed in very
small amounts, move the switch to R/A brie¯y and
then release it. Each time you do this, your vehicle
will go about 1 mph (1.6 km/h) faster.
The accelerate feature will only work after you set the
cruise control speed by pushing the SET button.
Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
·Push in the SET button until you reach the lower
speed you want, then release it.
·To slow down in very small amounts, push the SET
button brie¯y. Each time you do this, you'll 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 you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have 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 don't use
cruise control on steep hills.
3-10

Ending Cruise Control
There are two ways to turn off the cruise control:
·Step lightly on the brake pedal, or
·move the cruise switch to OFF.
Ending Speed Memory
When you turn off the cruise control or the ignition, or
shift into PARK (P) or NEUTRAL (N), your cruise control
set speed memory is erased.
Exterior Lamps
This control, located to the
left of the instrument
panel, operates the
exterior lamps.The exterior lamps control has three positions:
Off:Push the control all the way in to turn off all lamps
and lights.
Parking Lamps:Pull the control out, to the ®rst
position, to turn on the parking lamps together with the
following:
·Taillamps
·License Plate Lamps
·Sidemarker Lamps
·Instrument Panel Lights
Headlamps:Pull the control out all the way, to the
second position, to turn on the headlamps together with
the previously listed lamps and lights.
A warning chime will sound if you open the driver's door
when you turn the ignition switch to OFF, LOCK or
ACCESSORY with the lamps on.
3-11

Security Light
The SECURITY light will
come on when you turn the
key to START and stay on
until the vehicle starts.
It will also ¯ash if your ignition key is too dirty or wet for
the PASS-Key
žII system to read the resistor pellet.
SeePASS-KeyžII on page 2-17.
If the resistor pellet is damaged or missing, the light will
come on.
Cruise Control Light
The CRUISE light comes
on whenever you set the
cruise control, if equipped.
See ªCruise Controlº under
Turn Signal/Multifunction
Lever on page 3-5.
Low Washer Fluid Warning Light
The LOW WASH light will
come on when your
windshield washers are
working and the ¯uid
container is low.
The light will also come on brie¯y when your ignition is
turned on to show that it is working properly.
Door/Trunk Ajar Warning Light
The DOOR/TRUNK light
will come on if your trunk
or any door is not
completely closed.
3-36

Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if
it senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also upshift the transaxle to limit wheel spin.
This light will come on the
instrument panel cluster
while the Enhanced
Traction System is limiting
wheel spin. See
Enhanced
Traction System Warning
Light on page 3-28
.
You may feel or hear the system working, but this is
normal.
If your vehicle is in cruise control when the enhanced
traction system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. See ªCruise Controlº under
Turn Signal/Multifunction Lever on page 3-5.The Enhanced Traction System operates in THIRD (3)
and OVERDRIVE (
X). If you are in THIRD (3), the
system can upshift the transaxle to OVERDRIVE (
X).
The Enhanced Traction System is turned off in
SECOND (2) or FIRST (1) gear. See
Automatic
Transaxle Operation on page 2-23.
While the system is on,
this warning light will come
on the instrument panel
cluster to let you know
if there is a problem.
See
Enhanced Traction System Warning Light on
page 3-28. While this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System on. But you can turn the system off if
you ever need to. You should turn the system off if
the vehicle ever gets stuck in sand, mud or snow and
rocking the vehicle is required. See ªRocking Your
Vehicle To Get It Outº under
If You Are Stuck: In Sand,
Mud, Ice or Snow on page 4-31.

Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts
as needed. Replace any components that have high
effort or excessive wear. Do not lubricate accelerator
and cruise control cables.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
cha®ng, etc. Inspect disc brake pads for wear and rotors
for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
Check parking brake adjustment. You may need to have
your brakes inspected more often if your driving
habits or conditions result in frequent braking.
