Radio Reception
Usually, a problem with radio
reception does not mean there is a
problem with your radio - it is just the normal result of conditions
outside the vehicle. For example,
nearby buildings and terrain can
interfere with FM reception. Power
lines or telephone wires can
interfere with AM signals.
And of course, radio signals have a
limited range. The farther you are
from a station, the weaker its signal
will be. In addition, reception
conditions change constantly as
your vehicle moves.
Here are some common reception
problems that probably do not
indicate a problem with your radio.
FM Transmissions
Fading and drifting stations -
Generally, the effective range of FM
is about 40 km (25 miles). Once
outside this range, you may notice
fading and drifting, which increase
with the distance from the radio
transmitter. They are often
accompanied by distortion.
Multi-path - FM signals are
reflective, making it possible for two
signals to reach your antenna at the
same time. If this happens, the
signals will cancel each other out,
causing a momentary flutter or loss
of reception.
Static and fluttering - These occur
when signals are blocked by
buildings, trees, or other large
objects. Increasing the bass level
may reduce static and fluttering.
Station swapping - If the FM signal
you are listening to is interrupted or
weakened, and there is another
strong station nearby on the FM
band, your radio may tune in the
second station until the original
signal can be picked up again.
AM Transmissions
Fading - AM broadcasts are
reflected by the upper atmosphere -
especially at night. These reflected
signals can interfere with those
received directly from the radio
station, causing the radio station to
sound alternately strong and weak.
Station interference - When a
reflected signal and a signal
received directly from a radio station
are very nearly the same frequency,

Warning (Continued)
Do not add substances such as
gasoline or diesel fuel to the DEF
tank. You and others could be
seriously injured.
Caution
When opening the DEF tank cap,
be careful not to let dirt or other
foreign matter enter inside the
DEF tank. Intrusion of foreign
matter can cause a clogging of
the filter or affect the quality of
DEF, which may result in a SCR
system failure.
If DEF is spilled on the body or
frame, it may cause generation of
rust, so wipe it off and then rinse
it away with water.
When DEF dries it will leave a
crystalline residue, this condition is
normal. Wash with water or wipe
away the residue to prevent it from
entering the DEF tank. Adding DEF in Cold Weather
DEF freezes at low temperature but
the engine coolant circulates to
thaw the DEF tank and to prevent
DEF from freezing. Vehicle can be
driven normally when DEF is frozen.
If the refill diesel exhaust fluid (DEF)
warning light is on and the
remaining DEF in the DEF tank is
frozen, the warning lights, indicator
lights and restriction will not be
canceled until the DEF thaws even
if the DEF tank is refilled.
It is not recommended parking the
vehicle for long periods with the refill
diesel exhaust fluid (DEF) warning
light on in cold weather. The DEF
gauge will not register correctly
should the DEF freeze in this
condition causing the DEF low level
warning system not to reset when
DEF is added. Take the following
actions to avoid this condition in
cold weather:
1. Refill the DEF as soon as possible after parking the
vehicle. 2. Turn the engine control switch
to the ON position from the
LOCK position.
3. Wait for the warning buzzers and warning lights to turn off.
4. If the buzzer does not stop, return the engine control switch
back to the LOCK position and
add more DEF, and then start
over from step (2) above.
5. Turn the engine control switch to the LOCK position.
The DEF freezes at approximately
−11 °C (12 °F).
In cold weather, when the vehicle is
left without performing these actions
and the DEF tank freezes, the low
DEF level warnings and indicators
may not turn off when DEF is added
until after the tank defrosts.
Make sure to stop the engine before
adding the DEF. See Warning
Buzzers 091.
When DEF Freezes
Engine coolant circulates through
the DEF tank to thaw it when frozen
and prevent it from freezing while

Chevrolet Low Cab Forward Owner Manual (GMNA-Localizing-U.S.-
11254764) - 2018 - crc - 12/5/16
174 Driving and Operating
the engine is running. The vehicle
can be driven normally when DEF is
frozen in the DEF tank.
If the Refill DEF warning light is on
and the remaining DEF in the DEF
tank is frozen, the vehicle low level
warning system cannot be reset by
adding DEF. The DEF gauge will not
register correctly should the
remaining DEF freeze at this level.
Move the vehicle to a location to
allow the DEF to thaw. Once the
DEF is thawed the DEF gauge
should read correctly allowing the
low level warning system to reset.
To avoid this condition follow the
instructions for Adding DEF in Cold
Weather.
{Warning
Do not warm up the DEF tank
using a burner, heater, etc. You
and others could be seriously
injured.DEF Storage
Seal the container and store it in an
indoor place with good ventilation
avoiding direct sunlight.
When storing DEF, the shelf life
varies depending on the room
temperature of the storage place.
For details, please contact the
distributor of the DEF.
For storage of DEF, seal the
container to prevent the moisture
from evaporating.
Even when DEF has been frozen,
its quality is maintained when it is
thawed. It can be used as it is.
To store or carry DEF, use the
original container in which the DEF
was kept at the time of purchase.
Also, if other containers are used,
prepare a clean container for
exclusive use, which can be a
polyethylene resin tank (PE) or
stainless steel container, and do not
introduce foreign matter such as
water or contamination. DEF Disposal
Do not dispose of DEF and the
empty container into lakes, marine
areas, rivers, etc. DEF must be
disposed of in a method conforming
to the regulatory requirements in
your state.
Selective Catalytic Reduction
(SCR) System
The Selective Catalytic Reduction
(SCR) system reduces nitrogen
oxide (NOx) emissions emitted from
a diesel engine. The SCR system
reduces NOx by adding (injecting)
Diesel Exhaust Fluid (DEF) into the
exhaust system and inducing a
reaction converting NOx into water
vapor and nitrogen.
The SCR system consists of the
DEF tank, DEF Control Unit, DEF
Supply Pump and Injector, and the
SCR Catalyst. It is important to keep
a good supply of DEF in the DEF
tank at all times. Monitor the DEF
gauge to be sure the DEF tank level
does not become too low.

Driving and Operating 205
Press the cruise control main switch
again to turn the cruise control
system off. The cruise control main
indicator light will go out.
The cruise control set speed is
canceled in the following cases:
.When the brake pedal is
pressed.
. When the selector lever is
shifted to the N position.
. When cruising speed is
approximately 27 km/h (17
MPH). *
. When the vehicle speed
decreases more than 20% below
your set speed.
. When the cruise control main
switch is turned off. *
. When the engine control switch
is turned to the LOCK position. *
. When trouble develops in the
system. *
Memory speed is eliminated. *
When you do not use the cruise
control, be sure to place the cruise
control main switch into off. When you place the engine control
switch into ACC, place the cruise
control main switch into off, then
reset the cruise control if you want
to use the cruise control again.
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 do not use cruise
control on steep hills.
When Returning to Cruise Control
Driving
If you have canceled cruise control
under the following conditions, you
can return to the cruise control
driving condition before cancellation
when you operate and release the
cruise control resume switch. The
moment the resume switch is
released, the cruise set indicator
light comes on.
.
When pressing the brake pedal.
. When the selector lever is
shifted to the N position.
When the vehicle speed decreases
to 40 km/h (25 MPH) or less, it is
not possible to return to the cruise
control driving. You must reset the
cruise control.
If the cruise control is turned back
on while the vehicle speed exceeds
what is set prior to the cancellation
of cruise control, the set vehicle
speed cannot be changed until the
vehicle reaches to the set speed.
Also, the vehicle speed must be 1
MPH below the previously set
vehicle speed.
If you hold the switch at the +RES
position, the vehicle will keep going
faster until you release the switch or
apply the brake. So unless you want
to go faster, do not hold the switch
at the +RES position.
