2005 CHEVROLET SILVERADO brake light

You can chose among three driving settings:
2
m(Two-Wheel High):This setting is for driving in
most street and highway situations. Your front axle is not
engaged in two-wheel drive.
{CAUTION:
Shifting the transfer case to NEUTRAL can cause
your vehicle to roll even if the transmission is in
PARK (P). You or someone else could be
seriously injured. Be sure to set the parking
brake before placing the transfer case in
NEUTRAL. SeeParking Brake on page 2-51.
(N) NEUTRAL:Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle. See
Recreational Vehicle Towing on page 4-63orTowing
Your Vehicle on page 4-63for more information.
4
m(Four-Wheel High):This setting engages your
front axle to help drive your vehicle. Use four-wheel high
when you need extra traction, such as on snowy or icy
roads, or in most off-road situations.4
n(Four-Wheel Low):This setting also engages your
front axle to give you extra traction. You may never need
Four-Wheel Low. It sends the maximum power to all four
wheels. You might choose Four-Wheel Low if you were
driving off-road in sand, mud or deep snow and while
climbing or descending steep hills. When operating in
Four-Wheel Low, the gear ratio provides additional torque
when compared to four-wheel high. The transmission
gear shift feel will be exaggerated.
Indicator lights in the switches show you which setting
you are in. The indicator lights will come on briey when
you turn on the ignition and the last chosen setting will
stay on. If the lights do not come on, you should take your
vehicle in for service. An indicator light will ash while
shifting. Fast ashing means the conditions were not met
to make the desired shift, typically the vehicle was
going too fast, the automatic transmission was not in
neutral, or the clutch pedal was not fully depressed.
Slow ashing means the shift is in progress. It will stay on
when the shift is completed. If for some reason the
transfer cannot make a requested shift, it will return to
the last chosen setting.
2-47

Notice:Shifting the transmission into gear before
the Four-Wheel Low indicator light has stopped
ashing could damage the transfer case. To help
avoid damaging your vehicle, always wait for
the Four-Wheel Low indicator light to stop ashing
before shifting the transmission into gear.
If the Four-Wheel Low switch is pressed when your
vehicle is in gear and/or moving, the Four-Wheel Low
indicator light will ash for 30 seconds and not complete
the shift unless your vehicle is moving slower than
3 mph (5 km/h) and the transmission is in NEUTRAL (N).
The transfer case will shift to Four-Wheel High while
waiting to complete the shift.
Shifting from Four-Wheel Low to
Four-Wheel High or Two-Wheel High
To shift from four-wheel low to Four-Wheel High or
Two-Wheel High, your vehicle must be stopped or
moving less than 3 mph (5 km/h) with the transmission
in NEUTRAL (N) for an automatic transmission or the
clutch pedal depressed for a manual transmission.
The preferred method for shifting out of Four-Wheel Low
is to have your vehicle moving 3 mph (5 km/h).Press and release the Two-Wheel High or Four-Wheel
High switch. You must wait for the Two-Wheel High
or Four-Wheel High indicator light to stop ashing and
remain on before shifting your transmission into
gear or releasing the clutch pedal.
If the Four-Wheel High switch is pressed when your
vehicle is in gear and/or moving, the Four-Wheel High
indicator light will ash for 30 seconds but will not
complete the shift unless the vehicle is moving slower
than 3 mph (5 km/h) and the transmission is in
NEUTRAL (N).
{CAUTION:
Shifting the transfer case to NEUTRAL can cause
your vehicle to roll even if the transmission is
in PARK (P). You or someone else could be
seriously injured. Be sure to set the parking
brake before placing the transfer case in
NEUTRAL. SeeParking Brake on page 2-51.

Shifting into NEUTRAL
To shift the transfer case to NEUTRAL, rst make sure
the vehicle is parked so that it will not roll:
1. Set the parking brake.
2. Start the vehicle or turn the ignition to RUN.
3. Press the foot brake pedal and put the transmission
in NEUTRAL (N).
4. Shift the transfer case to Two-Wheel High.
5. Simultaneously press and hold the Two-Wheel High
and Four-Wheel Low buttons for 10 seconds.
The red NEUTRAL light will come on when the
transfer case shift to NEUTRAL is complete.
6. Start the engine if it is not already running.
7. Press and hold the foot brake pedal and Shift the
transmission to REVERSE (R) for one second,
then shift the transmission for one second to
DRIVE (D) for an automatic transmission, or
FIRST (1) for vehicles equipped with a manual
transmission and then let out the clutch. This is to
ensure the transfer case is in NEUTRAL. If not,
repeat this procedure starting at Step 3.
8. Turn the engine off, by turning the key to
ACCESSORY.
9. Place the transmission shift lever in PARK (P) for
an automatic transmission, or FIRST (1) for
vehicles equipped with a manual transmission.
10. Turn the ignition to LOCK.
Shifting Out of NEUTRAL
To shift out of NEUTRAL:
1. Set the parking brake and press and hold the
regular brake pedal.
2. Shift the transmission to NEUTRAL (N) for an
automatic transmission, or press the clutch pedal for
vehicles equipped with a manual transmission.
Then turn the ignition to RUN with the engine off.
3. Press the button for the desired transfer case shift
position (Two-Wheel High, Four-Wheel High, or
Four-Wheel Low).
4. After the transfer case has shifted out of NEUTRAL
the red light will go out.
5. Release the parking brake.
6. You may start the engine and shift the transmission
to the desired position. Excessively shifting the
transfer case into or out of the different modes may
cause the transfer case to enter the shift protection
mode. This will protect the transfer case from
possible damage and will only allow the transfer
case to respond to one shift per 10 seconds.
The transfer case may stay in this mode for up to
three minutes.
7. After the transfer case has shifted out of NEUTRAL
the red light will go out.

All-Wheel Drive
If your vehicle has the SS package, it may be equipped
with all-wheel drive. With this feature, engine power
is sent to all four wheels all the time.
This is like four-wheel drive, but there is no separate
lever or switch to engage or disengage the front axle.
It is fully automatic, and adjusts itself as needed for
road conditions.
Parking Brake
To set the parking brake, hold the regular brake pedal
down with your right foot. Push down the parking
brake pedal with your left foot.
A chime will activate and the warning light will ash
when the parking brake is applied and the vehicle
is moving at least 3 mph (5 km/h) for at least
three seconds.To release the parking brake, hold the regular brake
pedal down. Pull the bottom edge of the lever, located
above the parking brake pedal, with the parking
brake symbol, to release the parking brake.
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
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-69.

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 nd this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are four ways to turn off the cruise control:
Step lightly on the brake pedal,
move the cruise control switch to off, or
shift the transmission to NEUTRAL (N).
If the accelerator pedal is held for 60 seconds or
longer, cruise control will turn off.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Headlamps
The control on the driver’s side of your instrument panel
operates the headlamps.
Turn the control clockwise to operate the lamps.
The headlamp control has four positions:
9(Off):Turning the control to this position turns off
the Daytime Running Lamps (DRL) and the automatic
headlamps.
