Hazard Warning Flashers
The hazard warning flashers 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 top of the
steering column.
The hazard warning flashers work no matter what
ignition position the key is in, and even if the key is not
in the ignition.
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 will not work.
Other Warning Devices
If you carry reflective triangles, you can set them up at
the side of the road about 300 feet (100 m) behind
your vehicle.
Horn
Sound the horn by pushing the center of the steering
wheel. If you have the optional air horn, it is controlled
by a cord that you will find up above and to the left
of the driver. The harder you pull on the cord, the louder
the air horn will sound. The air horn works only after
your air brake system pressure gets up to about 115 psi
(790 kPa). The air horn will work properly unless the
air brake system pressure drops below 60 psi (415 kPa).

With cruise control, you can maintain a speed of about
30 mph (48 km/h) or more without keeping your foot
on the accelerator. Cruise control does not work
at speeds below about 30 mph (48 km/h).
If you have an automatic transmission and you apply
your brakes, the cruise control will shut off.
If you have a manual transmission and you apply your
brakes or push the clutch pedal, the cruise control
will shut 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.
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.
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. The
accelerator pedal will not go down.

Outlet Adjustment
Your vehicle has air outlets on the instrument panel that
allow you to adjust the direction and amount of airflow
inside the vehicle.
Move the lever on the outlet up or down to direct the
airflow. Increase or reduce the amount of airflow
by opening and closing the louvers. The outlets can be
moved side-to-side to direct the airflow.
Operation Tips
•
Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such as leaves). The
heater and defroster will work far better, reducing
the chance of fogging the inside of your windows.
•Keep the air path under the front seats clear
of objects. This helps air to circulate throughout
your vehicle.
•Adding outside equipment to the front of your
vehicle, such as hood-air deflectors, may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of your vehicle.
Rear Heating System
If you have a crew cab
and your vehicle has a
rear heater, the
thumbwheel for this
feature is located on the
headliner.
To increase and decrease the flow of heated air to the
rear floor vents, turn the thumbwheel to the desired
fan speed. To turn the fan off, turn the thumbwheel all
the way down.

Audio System(s)
If your vehicle came without a radio, the wiring
provisions for a radio and an antenna were installed at
the assembly plant, so that if you want, a radio can
be installed at the dealer.
Determine which radio your vehicle has and then read
the pages following to familiarize yourself with its
features.
Driving without distraction is a necessity for a safer
driving experience. SeeDefensive Driving on page 4-2.
By taking a few moments to read this manual and
get familiar with your vehicle’s audio system, you can
use it with less effort, as well as take advantage of
its features. While your vehicle is parked, set up your
audio system by presetting your favorite radio stations,
setting the tone and adjusting the speakers. Then,
when driving conditions permit, you can tune to your
favorite stations using the presets and steering
wheel controls if the vehicle has them.{CAUTION:
This system provides you with a far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and you
or others can be injured or killed. Always keep
your eyes on the road and your mind on the
drive — avoid engaging in extended searching
while driving.
Keeping your mind on the drive is important for safe
driving. For more information, seeDefensive Driving on
page 4-2.
