340 Vehicle Care
from industrial chimneys and other
foreign matter may damage vehicle
finishes if left on painted surfaces.
Prompt washing may not completely
remove all of these deposits. Other
cleaners may be needed. When
using chemical cleaners, be sure
they are safe for use on painted
surfaces.
Finish Damage
Any stone chips, fractures or deep
scratches in the finish should be
repaired promptly. Bare metal will
corrode quickly and may develop
into major repair expense. Minor
chips and scratches can be repaired
with touch up materials available
from your authorized dealer or other
service outlets. Larger areas of
finish damage can be corrected in
your dealer's body and paint shop.
Underbody Maintenance
Corrosive materials used for ice and
snow removal, and dust control can
collect on the underbody. If these
materials are not removed,
accelerated corrosion (rust) can
occur on underbody parts such asfuel lines, frames, floor pan and
exhaust system even though they
have been provided with corrosion
protection.
At least every spring, flush these
materials from the underbody with
plain water. Take care to clean well
any areas where mud and other
debris can collect. Sediment packed
in closed areas of the frame should
be loosened before being flushed.
If desired, your authorized dealer
can do this for you.
Interior Care
General
Remove dust and dirt from the
interior of the cab using an
automotive cleaner or vacuum
cleaner, and gently wipe surfaces
clean using a cloth wet with warm or
cold water.
{Warning
Water should never be sprayed
directly into the interior of the cab
when cleaning. Failure to observe
this precaution can lead to vehicle
malfunction and possibly to fire if
water should enter the audio
system or other electrical
components located underneath
the floor carpet.
Petroleum ether, gasoline and
other organic solvents should not
be used to clean safety belts. In
addition, safety belt webbing
should be neither bleached nor
redyed. Failure to observe these
precautions can lead to the
performance or strength of the
safety belts being impaired. In the
case of a collision, therefore, the
safety belts could be insufficiently
effective, and serious
life-threatening injuries could
result. When cleaning, use warm
water in which a small amount of

Warning (Continued)
neutral detergent has been
dissolved to gently wipe the
safety belts.
Follow the manufacturer's advice
whenever cleaning agents or
other chemicals are used, inside
or outside the vehicle. Some
cleaners may be poisonous or
flammable, and improper use may
cause personal injury or damage.
When cleaning the inside or
outside of the vehicle, do not use
volatile cleaning solvents, such as
acetone, lacquer thinners, enamel
reducers, nail polish removers; or
such cleaning materials as
laundry soaps, bleaches or
reducing agents, except as noted
in the following fabric cleaning
advice on stain removal. Never
use carbon tetrachloride,
gasoline, benzene or naphtha for
any cleaning purpose.(Continued)
Warning (Continued)
Open all vehicle doors for
ventilation when ANY cleaning
agents or other chemicals are
used in the interior. Overexposure
to some vapors may result in a
health problem that is more likely
to occur in small, unventilated
spaces.
You and others could be seriously
injured.
The interior of the vehicle must
never be cleaned using acidic or
alkaline solvents, or petroleum
ether, gasoline, and other organic
solvents. Failure to observe this
precaution can result in
discoloration and staining. It should
be noted that certain types of
cleaning products contain these
compounds. Be sure to read
cleaning product labels carefully.
Air fresheners (liquid, solid, gel or
plate types) must not come into
direct contact with, or spill onto,
interior components such as the air conditioning or audio system.
Compounds contained in these
products can cause discoloration,
staining or peeling of paint.
Glass cleaners that contain these
compounds must not be used to
clean the inside of the windshield or
window glass. To clean the glass,
wipe it using a cloth wet with warm
or cold water.
To avoid possible permanent
discoloration of light colored seats,
Do not let materials with non-fast
colors come into contact with seat
trim materials until these materials
are totally dry. This includes certain
types of casual clothing, such as
colored denims, corduroys, leathers
and suedes; also decorative paper,
With the use of modern trim
materials, it is very important that
you use proper cleaning techniques
and cleaners. Failing to do this on
the first cleaning may result in water
spots, spot rings or setting of stains
or soilage - all of which are more
difficult to remove in a second
cleaning.

342 Vehicle Care
Dust and loose dirt that collect on
interior fabric should be removed
often with a vacuum cleaner or soft
bristle brush. Wipe vinyl or leather
trim regularly with a clean, damp
cloth. Normal trim soils, spots or
stains can be cleaned with these
cleaners.
Remember these basic steps before
cleaning:
.Remove stains as quickly as
possible before they
become "set".
. Use a clean cloth or sponge,
and change to a clean area
often. A soft brush maybe used
if stains persist.
. Use solvent-type cleaners only
in a well ventilated area: also, do
not saturate the stained area.
. If a ring forms after spot
cleaning, clean the entire area
immediately.
. Follow specific instructions on
cleaner labels.General Cleaning of Soiled or
Water Spotted Fabric Type
Trim with Foam Type Cleaner
Vacuum the area thoroughly to
remove any loose dirt.
Always clean a whole trim panel or
section. Mask surrounding trim
along stitch or welt lines.
Use suds on a clean sponge. Do
not brush wet suede. Do not
saturate the material or rub it
harshly. Immediately after cleaning,
remove suds with a sponge and
rinse with a clean wet sponge. Wipe
off remaining residue with a slightly
damp absorbent towel or cloth.
Important —Immediately after
wiping, force-dry the fabric with an
air hose. A heat dryer or heat lamp
may be used. Use caution with a
heat dryer or lamp to help prevent
damage.
When trim materials with a sheen or
luster finish are dry, wipe the fabric
lightly with a soft, dry, clean cloth to
restore its sheen or luster. For suede, raise nap with dry scrub
brush and vacuum to remove any
final traces of residue.Spot Cleaning Fabric Type
Trim with Solvent Type Cleaner
Before trying to remove a spot or
stain from fabric, try to find out the
type and age of the spot or stain.
Some spots or stains can be
removed with water or a mild soap
solution. Spots or stains should
always be removed as soon as
possible.
Some types of stains or soilage,
such as lipstick, inks and grease,
are very difficult (sometimes
impossible) to remove completely.
When cleaning this type of stain or
soilage, be sure not to enlarge the
soiled area.
.
Gently scrape excess stain from
the trim material with a clean,
dull knife or scraper. Use very
little cleaner, light pressure, and
clean cloths (preferably
cheesecloth). Cleaning should
start at the outside of the stain

Vehicle Care 343
"feathering" towards the center.
Keep changing to a clean
section of cloth.
. When you clean a stain from
fabric, immediately dry the area
with an air hose, heat dryer,
or heat lamp to help prevent a
cleaning ring. (Use caution with
heat dryer or lamp to help
prevent fabric damage.)
. If a ring forms, immediately
repeat the cleaning operation
over a slightly larger area with
emphasis on "feathering"
towards its center. If a ring still
remains, mask off surrounding
trim sections and clean the
entire soiled area with foam type
cleaner.

Maintenance
Schedule
Make sure the vehicle is inspected
at regular intervals. Inspections and
maintenance enable you to use the
vehicle with peace of mind. They
also extend the vehicle's
service life.
For safe and economical driving, we
recommend that you have your
vehicle inspected and serviced
regularly according to the schedule
indicated in this chapter.
To drive your vehicle safely and at
minimum cost, it is essential to have
your vehicle regularly inspected and
serviced at your dealer as per the
specified maintenance schedule.
Contact your dealer for inspection
that requires disassembly and/or
special equipment.
The Maintenance Schedule in this
manual and a Warranty Information
Booklet are supplied with your
vehicle. Read all publications for a
full understanding of your vehicle's
maintenance needs. The quality of maintenance your
new vehicle receives is as important
as the regularity with which it is
serviced. Authorized dealers provide
nationwide quality in customer
service. The program includes the
training of dealer technicians
throughout the country and is
supported with a continuous
follow-up of publications and other
service information. The use of
genuine parts and accessories,
which have the same high quality
standards as original equipment
parts, and the use of factory
approved tools developed and
tested for use by the authorized
dealer also contribute to the high
quality of service.
If you have any questions on how to
keep your truck or chassis in good
condition, see your authorized
dealer, the place many truck owners
choose to have their maintenance
work done. Your authorized dealer
can be relied upon to use proper
parts and practices.
Some of these services can be
complex, so unless you are
technically qualified and have the

Chevrolet Low Cab Forward Owner Manual (GMNA-Localizing-U.S.-
10716700) - 2017 - crc - 12/6/16
346 Service and Maintenance
necessary equipment, you should
let your authorized dealer's service
department or another qualified
service center do these jobs.
The schedule includes general
maintenance which you or a
qualified technician should perform
periodically.
Explanation of Vehicle
Maintenance and Log
The following is a brief explanation
of normal vehicle use.
NORMAL VEHICLE USE—The
maintenance instructions contained
in this section are based on the
assumption that your vehicle will be
used as designed:
.To carry passengers and cargo
with the limitations indicated on
the vehicle VIN and GVW plate.
. On reasonable road surfaces
within legal operating limits.
. On a daily basis, as a general
rule, for at least several miles/
kilometers. Unusual operating conditions, such
as driving in dusty areas (sweeper,
agricultural or off-road vehicles),
extended idling (refrigeration
vehicles), or vehicles operated for
frequent short trips, will require
more frequent vehicle maintenance.
The log groups items according to
mile/kilometer service intervals. Use
the item codes (letter and number)
to find the description of the
maintenance and the time intervals.
Follow whichever interval comes
first, time or miles/kilometers.
After the maintenance services are
performed, insert the month, day
and mileage/ kilometers in the area
provided next to the serviced item.
The services shown up to
176 000 km (110,000 miles) are to
be repeated after the initial
176 000 km (110,000 miles) at the
same intervals.
Severe Driving Conditions
A vehicle operated under severe
conditions (see list below) requires
more frequent maintenance. .
Frequent short trips of less than
6 kilometers (4 miles) in
moderate temperatures
. Frequent short trips of less than
16 kilometers (10 miles) in sub-
freezing temperatures
. Frequent and extended low-
speed engine operation (door-
to- door deliveries, stop- and- go
traffic, etc.)
. Driving on unpaved roads with
heavy dust
. Towing a trailer
Preventive Maintenance
As any mechanical device operates,
a certain amount of wear occurs.
The amount of wear depends on
certain variables –type and method
of operation and the schedule of
maintenance. These variables may
be emphasized as critical to
malfunction but each is dependent
upon the other. For example, if a
vehicle is repeatedly overloaded,
driven at excessive speed or
improperly shifted, no schedule of
maintenance can prevent
malfunction. Also, if a preventive

Chevrolet Low Cab Forward Owner Manual (GMNA-Localizing-U.S.-
10716700) - 2017 - crc - 12/6/16
Service and Maintenance 347
maintenance schedule is not
followed, or is improperly carried
out, no amount of correct vehicle
operation will prevent malfunction.
If vehicle application, operation and
preventive maintenance schedules
and procedures are followed and
properly carried out, the life of the
vehicle will be greatly extended.
For example, regular attention to the
engine oil is essential. The oil level
must be periodically checked and oil
added whenever needed. Also, the
oil should be changed at the
intervals specified with the proper
quality and viscosity of oil. If your
engine should run excessively low
on oil or if the oil has lost its
lubricating qualities because of old
age, serious engine damage could
occur.
