194 Driving and Operating
If the DEF level becomes too low or
incorrect fluid is added to the DEF
tank, the warning buzzer will sound,
warning and indicator lights will
come on and engine power will be
reduced. If you see these warning
and indicator lights, add DEF as
soon as possible or have your
vehicle serviced as soon as
possible.
Continuing to drive for too long after
these lights come on will result in
additional warnings, more engine
power reduction and will eventually
result in a severe vehicle speed
limitation. See“Diesel Exhaust
Fluid (DEF) Low Level Warning” and
“Incorrect Diesel Exhaust Fluid
(DEF)/SCR System Malfunction
Warnings” later in this section.
{Warning
Do not touch the water that
comes out from the muffler. The
water is mildly acidified due to the
action of oxidation catalyst inside
the muffler. In the event that the
(Continued)
Warning (Continued)
fluid does come into contact with
your skin, completely wash it off
with water. You and others could
be seriously injured.
Do not relocate or modify the
exhaust pipe, muffler, DPF, SCR,
or DEF tank, which may affect the
exhaust gas cleaning performance.
If any relocation or modification is
necessary, consult your dealer.
The SCR system continues to
operate for approximately 3 minutes
after the engine control switch is
turned to the "LOCK" position. It is
normal to hear a buzzing type noise
from the DEF supply pump
(mounted on the left side frame rail
behind the cab) during the
shutdown process.
If it is necessary to disconnect the
batteries for any reason, be sure to
wait at least 3 minutes after turning
the engine control switch to the
"LOCK" position. This will allow the SCR system to properly complete
its shutdown processes. See
Winter
Driving 0145.
Diesel Exhaust Fluid (DEF) Low
Level Warning
Diesel Exhaust Fluid (DEF) is a
required fluid for the operation of
your diesel engine just as diesel fuel
is required. To avoid running out of
DEF your vehicle will turn on
warning and indicator lights and
reduce engine power in progressive
stages to encourage adding DEF.
The following is a summary of the
diesel exhaust fluid (DEF) low level
warning lights, indicator lights and
engine power reductions.
Continuing to drive for too long after
these lights come on will eventually
result in a severe vehicle speed
limitation.
These warning and indicator lights
will go out automatically and engine
power will be restored to normal
after the SCR system detects that
the DEF tank is refilled with DEF.

240 Driving and Operating
Filling the Tank
Be sure to obey the following
instructions when refueling the
vehicle:
.Stop the engine and close the
vehicle's doors and windows.
. Keep cigarettes and other
flames away from the vehicle.
. Before opening the fuel tank
filler cap, touch a metallic object
to discharge static electricity
from your body.
. When filling, place the nozzle
deeply into the fuel tank. If you
try to fill more fuel by pulling out
the nozzle from the fuel tank, the
fuel may spill out, thus causing
danger.
. Be sure to wipe off the fuel that
is spilled at refueling.{Warning
Fuel vapor is highly flammable.
Be careful not to inhale fuel vapor
when refueling the vehicle.
If you have a static charge
buildup on your body while
refueling the vehicle, a spark
caused by its discharge could
ignite the fuel, resulting in burns.
All parts of the refueling
procedure (from opening the fuel
tank filler cap to completing the
refueling and closing the fuel tank
filler cap) must be performed by
the same person.
Other people may be carrying
static electricity. Do not allow
them to approach the fuel filler.
The person performing the
refueling procedure must not
return to the seat in the cab
part-way through the procedure.
(Continued)
Warning (Continued)
He/she could pick up another
charge of static electricity by
doing so.
Obey all cautions posted in filling
stations.
Type A
In the case of Type A, grip the tab of
the fuel tank filler cap when turning
the cap to open or close.

Driving and Operating 241
Type B
After refueling, make sure that the
fuel tank filler cap is tightly closed.
Do not use any fuel tank filler cap
that is not a genuine GM part.
The use of an improper fuel tank
filler cap could cause fuel spillage in
the event of an accident. The use of
an improper fuel tank filler cap could
also affect the fuel system and the
emission control system.
Be sure to wipe off the fuel that is
spilled at refueling.
{Warning
Fuel may be under pressure. Be
sure to slowly open the fuel tank
filler cap. If you open it quickly,
fuel may spurt out. You and
others could be seriously injured.
Caution
Care must be taken when filling
the fuel tank to prevent entry of
dirt and water.

Installing Electrical Equipment
{Warning
Inappropriate installation or
removal of audio, radio or other
electrical equipment can
adversely affect other electrical
equipment and cause a
breakdown or fire. Be sure to
have electrical equipment
installed or removed by your
dealer. You and others could be
seriously injured.
Do not install any unauthorized
radio set, or any radio set or
antenna that does not comply with
relevant standards. Noise from the
radio set could cause
electromagnetic interference with
the vehicle's electronic equipment
