Chevrolet Low Cab Forward 4500 2019 Series Owner's Manual page 156

Turn the power of the dome light or
accessories OFF before starting the
engine. See Seat Position 0 36,
Seat Belts 0 41, Steering Wheel
Adjustment 0 62, and Mirrors 0 31.
Keep the Floor Around the
Driver's Seat Clean and Tidy
Warning
It is extremely dangerous to have
empty cans, empty bottles or
other items rolling around on the
floor because they could get
trapped under the brake pedal
and prevent brake application.
For proper pedal operation, it is
also essential to lay floor mats
properly. Incorrectly installed floor
mats would hinder free movement
of the pedals.
Do not use the dashboard pocket
or the top of the dashboard as a
place to put items that could roll,
which could interfere with your
driving. You and others could be
seriously injured.
Choose Your Footwear Suitable
for Driving
Warning
Choose footwear that ensures
proper operation of pedals when
driving the vehicle. Use of
footwear unsuitable for driving
may cause an accident.
Checks Before Operating
Allow the engine to warm up before
driving. While the engine is warming
up, the following checks should
be made:
1. Observe the engine oil
pressure warning light. The
light should go out when the
engine is running. If it stays on,
shut the engine off and find the
cause.
2. Look at the engine coolant
temperature gauge. If the
gauge reaches the H (HOT)
area, stop the engine and find
the cause of the overheating.
Driving and Operating
3. Check that the battery warning
light has gone out. The light
should go off and stay off at
normal idle speeds. If the light
does not go out or comes on
during normal operation, have
the charging system checked.
4. Check that the brake low
vacuum warning light is out
and that the vacuum buzzer is
not sounding. It is normal for
the warning buzzer to sound
for a few seconds after the
engine starts. If the light and
buzzer remain on, do not drive
the vehicle until the cause has
been found and corrected.
5. Look at the brake system
warning light. It should be out
when the parking brake is
released and the engine is
running. If it stays on, it could
mean that the brake fluid level
is low. Check the brake fluid
reservoir. This condition must
be corrected before moving the
vehicle.
