Pull the lever, located
just above the parking
brake pedal, marked
BRAKE RELEASE.
If the ignition is on when the parking brake is released,
the brake system warning light will go off.
NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat. You may have to
replace them, and you could also damage other
parts of your vehicle. Always check to be sure
your parking brake is fully released before
you drive.
If you are towing a trailer and are parking on any hill,
see ªTowing a Trailerº in the Index. That section shows
what to do first to keep the trailer from moving.
If you have a 3500 HD model, it is recommended that
the propshaft
-mounted parking brake be burnished as
part of the new vehicle break
-in. The parking brake
will work best after it has been burnished following
these instructions.
Make 10 stops, using the parking brake foot pedal, from
20 mph (32 km/h) about 2 1/2 miles (4 km) apart. In
between stops, drive the vehicle at 20 mph (32 km/h).

The driver's window also has an express-down feature
that allows the window to be lowered without holding
the switch. Press and hold the side of the window switch
marked AUTO for one second to activate the
express
-down mode. The express-down mode can be
canceled at any time by pressing the opposite side of the
switch. To open the window partway, lightly tap the
switch until the window is at the desired position.
Lockout Switch (Crew Cab)
If you have a Crew Cab and power windows, the power
window switch has a lockout feature. This feature
prevents the rear windows from operating when the
front driver's side switch is in LOCK. The windows can
still be operated using the driver's window switch.
When the switch is moved to NORM, the rear power
windows will operate again.
Swing-Out Windows (Extended Cab)
To open a rear swing-out
window, just flip the
latch open and swing
the glass out.
The latch will catch when the window is fully open and
will hold the window in the open position.
Sliding Rear Window (If Equipped)
To open the sliding rear window, unlock the latch lever
by moving the lever toward the front of the cab. Release
the lever from the latch plate and slide the window
toward the driver's side of the vehicle.
To close the window, slide the window toward the
passenger's side of the vehicle. The latch lever will
automatically snap locked on to the latch plate. Try to
open the window without releasing the latch lever to be
sure the window is in the locked position.

2-36 Turn Signal and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow
you to signal a turn or a lane change.
To signal a turn, move the lever all the way up
or down. When the turn is finished, the lever will
return automatically.
An arrow on the instrument
panel will flash in the
direction of the turn or
lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it.If you move the lever all the way up or down, and the
arrow flashes at twice the normal rate, a signal bulb
may be burned out and other drivers may not see your
turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you
signal a turn, check for burned
-out bulbs and a blown
fuse (see ªFuses and Circuit Breakersº in the Index).
Headlamp High/Low-Beam Changer
To change the headlamps from low to high beam or high
to low beam, pull the multifunction lever all the way
toward you. Then release it.
When the high beams
are on, this light on the
instrument panel also
will be on.

2-37 Windshield Wipers
You control the windshield
wipers by turning the knob
with the wiper symbol on it.
For a single wiping cycle, turn the knob to MIST. Hold
it there until the wipers start, then let go. The wipers will
stop after one cycle. If you want more cycles, hold the
knob on MIST longer.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain or
snow. Turn the knob to choose the delay time. The
closer to LOW, the shorter the delay.For steady wiping at low speed, turn the knob to the
LOW position. For high
-speed wiping, turn the knob
further, to HIGH. To stop the wipers, turn the knob
to OFF.
Damaged wiper blades may prevent you from seeing
well enough to drive safely. To avoid damage, 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 your blades do become
damaged, get new blades or blade inserts.
Heavy ice or snow can overload your wipers. The
windshield wiper motor is protected from overload by a
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. Although protected from electrical overload,
overload due to heavy snow, etc. may cause wiper
linkage damage. Always clear ice and heavy snow from
the windshield before using your windshield wipers.

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 to R/A for less
than half a second. Each time you do this, your
vehicle will go about 1 mph (1.6 km/h) faster.)
Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:

Press in the 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
button for less than half a second. Each time you do
this, you'll go 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. If the steepness
of the hill causes the vehicle speed to drop more than
15 mph (24 km/h) below the set speed, your cruise control
will automatically disengage. 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 or

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.

ACCESSORY, the buzzer can be turned off by turning
the thumb wheel next to the parking lamp/headlamp
knob all the way down.

2-42 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.
The DRL system will make your headlamps come on at
a reduced brightness when:

the ignition is on,

the headlamp switch is off 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.
Your instrument panel won't be lit up either.
When it begins to get dark, your DRL indicator light is a
reminder to turn your headlamp switch on. The other
lamps that come on with your headlamps will also
come on.
When you turn off the headlamp switch, the regular
lamps will go off, and your headlamps will change to
the reduced brightness of DRL.To idle your vehicle with the DRL off, set the parking brake.
The DRL will stay off until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Interior Lamps
Instrument Panel Intensity Control
The instrument panel intensity control is located to the
right of the headlamp switch.
Rotate the thumb wheel up to adjust instrument panel
lights. Rotate the thumb wheel up to the first notch to
return the radio display and gearshift indicator LED
display to full intensity when the headlamps or parking
lamps are on. To turn on the dome lamps (with the
vehicle doors closed) rotate the thumb wheel up to the
second notch position.
Illuminated Entry
Your vehicle is equipped with an illuminated
entry feature.
When the doors are opened, the dome lamps will come
on if the dome lamp button is out. When all the doors
are closed, or the dome lamp button is pressed in, the
lamps will stay on for a short period of time and will
then go out.
