Hazard Warning Flashers
Your hazard warning flashers let you warn others. They
also let police know you have a problem. Your front
and rear turn signal lamps will flash on and off.The hazard warning
flasher button is located on
the top of the steering
column.
Your hazard warning flashers work no matter what
position your key is in, and even if the key isn’t in.
Press the button to make the front and rear turn signal
lamps flash on and off. Press the button again to
turn the flashers off.
When the hazard warning flashers are on, your turn
signals won’t work. The flashers will stop if you step on
the brake.

Cruise Control
With 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).
If you apply your brakes, the cruise control will shut off.
{CAUTION:
Cruise control can be dangerous where
you can not 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
needless wheel spinning, and you could
lose control. Do not use cruise control on
slippery roads.
Setting Cruise Control
{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.
If your vehicle has this
feature, the controls are
located on the end of
the turn signal/multifunction
lever.
OFF:Move the switch to this position to turn the cruise
control off.
3-9

ON:Move the switch to this position to turn the cruise
control on.
R/A (Resume/Accelerate):Move the switch to this
position to maintain a desired speed after braking.
SET:Press this button at the end of the lever to set
your desired speed.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Press in the SET button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
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 briefly from ON to
R/A (Resume/Accelerate).
You’ll go right back up to your chosen speed and stay
there.
If you hold the switch at R/A, the vehicle will keep going
faster until you release the switch or apply the brake.
So unless you want to go faster, don’t hold the switch
at R/A.
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’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 briefly to
R/A. 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 lower speed you want, then
release it.
•To slow down in very small amounts, press the
SET button briefly. Each time you do this, you’ll
go about 1 mph (1.6 km/h) slower.
3-10

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 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 find this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
•Step lightly on the brake pedal.
•Move the cruise switch to OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Exterior Lamps
The control on the driver’s side of the instrument panel
operates the exterior lamps.
The exterior lamp control has three positions:
9(Off):Turn the exterior lamps control all the way
counterclockwise to turn off the lamps and put the
system in automatic headlamp mode.
3-11

;(Parking Lamps):Turning the exterior lamps
control to this position turns on the parking lamps
together with the following:
•Sidemarker Lamps
•Taillamps
•License Plate Lamps
•Instrument Panel Lights
O(Headlamps):Turning the exterior lamps control to
this position turns on the headlamps, together with
the previously listed lamps and lights.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor on the
top of the instrument panel under the radio speaker grill.
Be sure it is not covered or the system will be on
whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is off.
Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamps when you need them.
You may be able to turn off your automatic headlamp
system. See “Daytime Running Lamps (DRL)” later
in this section for more information.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. See “Instrument
Panel Brightness Control” underInterior Lamps
on page 3-15.
3-12

Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on, the driver’s door
is opened and your ignition is in OFF, LOCK or
ACCESSORY. To turn the chime off, turn the control
counterclockwise or turn the instrument panel brightness
thumbwheel down to the fully dimmed position. In the
automatic mode, the headlamps turn off once the ignition
key is in OFF.
Daytime Running Lamps
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
first sold in Canada.The DRL system will make your headlamps come on
at reduced brightness when the following conditions
are met:
•The ignition is on,
•the exterior lamp control is in OFF,
•the sensor detects daytime light,
•an automatic transmission is not in PARK (P), and
•the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel won’t be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.
The DRL system on some vehicles may turn off
temporarily while the turn signals are activated.
To idle an automatic transmission vehicle with the DRL
off, put the transmission in PARK (P). To idle a
manual transmission vehicle with the DRL off, set the
parking brake. The DRL will stay off until you shift out of
PARK (P) or release the parking brake.
The following does not apply to vehicles sold in Canada.
3-13

Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
Your vehicle’s hydraulic brake system is divided into two
parts. If one part isn’t working, the other part can still
work and stop you. For good braking, though, you need
both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.This light should come on briefly when you turn the
ignition key to RUN. If it doesn’t come on then, have it
fixed so it will be ready to warn you if there’s a
problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
floor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-45.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is on.
Driving with the brake system warning light on
can lead to an accident. If the light is still on
after you have pulled off the road and stopped
carefully, have the vehicle towed for service.

Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several seconds. That’s
normal.
If the light stays on, or comes on when you’re driving,
your vehicle needs service. If the regular brake
system warning light isn’t on, you still have brakes, but
you don’t have anti-lock brakes. If the regular brake
system warning light is also on, you don’t have anti-lock
brakes and there’s a problem with your regular
brakes. SeeBrake System Warning Light on page 3-27.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If
the light doesn’t come on then, have it fixed so it will be
ready to warn you if there is a problem.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, your engine is
too hot!
It means that your engine coolant has overheated. If
you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-26for more
information.
