Towing the Vehicle
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
Proper equipment must be used to
prevent damage to vehicles during
any towing. State and local laws
which apply to vehicles in tow must
be followed. Vehicles should not be
towed at speeds in excess of
88 km/h (55 mph).
Connect to the main structural parts
of the vehicle. Do not attach to
bumpers, tow hooks or brackets.
Use only equipment designed for
this purpose. Follow the instructions
of the wrecker manufacturer.
A safety chain system must
be used.
The procedures below must be
followed when towing to prevent
possible damage.Front End Towing (Front Wheels
Off Ground)
To prepare a disabled vehicle for
front end towing with front wheels
raised off theground, the following
steps are necessary:
.
Block the rear wheels of the
disabled vehicle.
. For gasoline vehicles, move the
selector lever into "N" position,
vehicles can be towed at speeds
below 48 km/h (30 mph) and up
to distances less than
80 km (50 mi).
. Disconnect the driveshaft at the
rear axle. Secure the driveshaft
to the frame or crossmember.
When towing, disconnect the
driveshaft at the rear axle to ensure
the transmission is not damaged.
The rear end of the driveshaft must
be disconnected and safely secured
if the 80 km (50 mi) or 48 km/h
(30 mph) is exceeded. If there is damage or suspected
damage to the rear axle, remove the
axle shafts. Cover the hub openings
to prevent the loss of lubricant or
entry of dirt or foreign objects.
Place a 10 cm (4 in) wood beam
against the towing guide behind the
bumper. (If no 10 cm (4 in) is
available, then remove the bumper.)
Ensure towing chains do not come
into contact with the horns or the
bumper. (If towing chains contact
the bumper, then remove the
bumper.)

oil, if required.
Rear End Towing
When towing a vehicle with rear
wheels raised, secure the steering
wheel to maintain straight-ahead
position. Make certain that the front
axle is not loaded beyond the front
axle gross axle weight rating
(GAWR) as indicated on the
vehicle's VIN and weight rating plate
(diesel) or the vehicle's "Vehicle
Certification and Greenhouse Gas
(GHG) Emissions Plate" (gasoline).
Special Towing Instructions1. All state and local laws regarding such items as
warning signals, night
illumination, speed, etc., must
be followed.
2. Safety chains must be used.
3. No vehicle should ever be towed over 88 km/h (55 mph). 4. Loose or protruding parts of
damaged vehicles should be
secured prior to moving.
5. A safety chain system completely independent of the
primary lifting and towing
attachment must be used.
6. Operators should refrain from going under a vehicle which is
being lifted by the towing
equipment unless the vehicle is
adequately supported by safety
stands.
7. No towing operation which for any reason jeopardizes the
safety of the wrecker operator
or any bystanders or other
motorists should be attempted.Appearance Care
Exterior Care
Exterior Finish
The paint finish on your vehicle
provides beauty, depth of color,
gloss retention and durability.
While cleaning the vehicle, do not
grip the roof marker lights to prevent
damage or water leakage.
Washing
The best way to preserve your
vehicle's finish is to keep it clean by
washing it often.
Wash the vehicle in lukewarm or
cold water. Do not use hot water or
wash your vehicle in the direct rays
of the sun. Do not use strong soap
or chemical detergents. All cleaning
agents should be flushed promptly
from the surface and not allowed to
dry on the finish.
These vehicles are designed to
operate under normal environmental
conditions to withstand natural
elements. However, unusual

Chevrolet Low Cab Forward Owner Manual (GMNA-Localizing-U.S.-
10716700) - 2017 - crc - 12/6/16
Vehicle Care 335
conditions such as high-pressure
car washers may cause water to
enter inside the vehicle. If the
vehicle is operated with foreign
material adhering to the exterior,
this material may react chemically
with paint, resulting in staining,
discoloration, rusting or corrosion of
components. Also, the material may
become trapped within mechanical
components, adversely affecting
their functions or forming an
aerodynamic resistance. In the
following cases, therefore, the
vehicle must be washed and all
foreign matter removed.
.When soot, iron powder, dead
bugs, bird droppings, tree sap or
oily matter from coal tar and
smoke has adhered to painted
surfaces.
. When the vehicle has been
driven in coastal areas.
. When the vehicle has been
driven on roads where road
chemicals have been applied.
. When a large amount of mud or
dirt has adhered to the exterior. To wash the vehicle:
1. Fully turn on the tap, and wash out the undercarriage and
suspension.
2. Close all openings and wash the cab and cargo body panels
using a neutral detergent.
3. Clean wheels and tires using a brush and detergent.
4. After washing away all remaining detergent, use a
shammy or other clean cloth to
fully remove all moisture and
water droplets
{Warning
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
(Continued)
Warning (Continued)
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. 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.
Do not apply water directly in order
to clean the cab interior. Failure to
observe this precaution can result in
malfunction or breakdown of
electronic control units and electrical
components, or in rusting of the cab

336 Vehicle Care
floor. Do not apply water from a
high-pressure washer nozzle
directly to the electric connectors.
Failure to observe this precaution
can lead to faulty operation of the
electrical system. If an automatic
car or truck-wash is used with
vehicles having dark or metallic
coating, the painted surfaces can be
damaged by the brushes, lose their
luster or be very noticeably
scratched.
Do not direct a large amount of
water at the air inlet openings. Do
not apply water to the engine
compartment or at electrical
components. Failure to observe this
precaution can lead to a poorly
starting and operating engine and
problems in the electrical system.
Ensure that mirrors and the antenna
are retracted before washing the
vehicle.
If an automatic car or truck-wash
must be used, avoid a
high-temperature, high pressure
type machine. Failure to observe
this precaution can lead to heat
deformation and breakage of plastic
components, or to water leaks intothe cab. When using an automatic
car or truck-wash, ensure that a
distance of at least 0.4 m
(15.75 inches) is maintained
between the nozzle and the vehicle,
and when washing door windows,
that the spray is perpendicular to
the surface of the glass.
Ensure that all detergent is fully
washed and wiped away.
Particularly in the case of strong
alkaline detergents (typically those
for industrial uses), there is a
danger that hairline cracks can
develop in lighting-cluster lenses if
the vehicle is operated without
detergent being fully wiped away.
Always read the detergent
manufacturer's instructions carefully
before use. Airborne dirt that
adheres to plastic front bumpers as
a result of rain, for example, can be
difficult to remove. In such a case,
use a commercially-available
cleaner to clean away the dirt, and
then apply a wax for use with plastic
components.Vehicle Storage
In order to maintain your vehicle's
attractive appearance as long as
possible, special consideration must
be given to its storage location.
If the vehicle is stored or kept for an
extended period of time in any of
the following locations, a chemical
change may occur in the paint work,
resulting in staining, discoloration,
rusting, and corrosion of
components.
.
Locations where a large amount
of oily matter, soot, heavy smoke
or metal powder can adhere to
the vehicle.
. Areas around pharmaceutical
plants and other facilities that
discharge chemical matter.
. Coastal areas
. Locations where a large amount
of dead bugs, bird droppings or
tree sap can adhere to the
vehicle.

Vehicle Care 337
Polishing and Waxing
Periodic polishing and waxing is
recommended to remove built-up
residue and eliminate any
"weathered" appearance.
Your authorized dealer offers
several polishes and cleaners which
have proven value in maintaining
original finish appearance and
durability.
Painted and chrome-plated surfaces
should be waxed once or twice a
month, or whenever water is being
poorly repelled on the surfaces.
Ensure that wax is not applied in
direct sunlight, and that the
temperature of the painted surface
is no more than 40 °C (104 °F).
Always follow the instructions
provided with your wax product.
Do not use wax containing abrasive
material. Failure to observe this
precaution can lead to scratching of
painted surfaces or plastic
components.
The application of wax to rubber
component surfaces can result in
permanent whitening.Wax must not be applied to the
windshield. Failure to observe this
precaution can result in irregular
reflection of light, impairing
your view.
Protecting Exterior Bright Metal
Parts
Bright metal parts should be
cleaned regularly to keep their
luster. Washing with water is all that
is usually needed.
Use special care with aluminum
trim. To avoid damaging protective
trim, never use auto or chrome
polish, steam or caustic soap to
clean aluminum. A coating of wax,
rubbed to a high polish, is
recommended for all bright metal
parts.
Weatherstrip Lubrication
All weatherstrips should be
periodically lubricated (minimum of
every 6 months) with a silicone
grease lubricant. A thin film of
silicone grease lubricant should be
applied using a clean cloth. Silicone
grease application will lengthen
weatherstrip life, help sealing, and
assist in eliminating squeaks.
Windshield Care
Wax must not be applied to the
windshield. A layer of wax can
impair your view in rainy weather
and can also lead to rough
movements of the windshield wiper.
If engine oil or grease comes into
contact with the windshield, staining
or discoloration may result. It must
be immediately cleaned away.
If not fully cleaned by the windshield
wipers, the windshield should be
cleaned using glass cleaner. If your
windshield is not clear after using
the windshield washer, or if the
wiper blade chatters when running,
wax or other material may be on the
blade or windshield.
The windshield wipers on your truck
can be pulled out from the
windshield to provide easier access
for cleaning.
Clean the outside of the windshield
with a non-abrasive cleaner. Your
windshield is clean if beads do not

338 Vehicle Care
form when rinsing with water. Clean
the blade by wiping with a cloth
soaked in a solution of one-half
water and one-half methanol
alcohol. Then rinse the blade with
water.
The windshield wiper arms may be
swung out, away from the glass, to
provide easy access for cleaning.
Do not hang on to the roof marker
lights while cleaning the windshield
or damage may occur (resulting in
possible water leakage).
External Diesel Engine
Cleaning
The engine does not need periodic
cleaning, nor is it recommended.
If you insist on cleaning the engine,
clean it only when it is cold, never
when it is warm or hot, and never
when the engine is running.
Spraying or pouring water or other
fluids on your engine when it is
warm or hot, or when it is running,
can cause serious damage to the
engine and its components,
particularly the fuel supply pump.

Vehicle Care 339
Cooling efficiency is compromised
when there is dirt or dust plugging
air passages in the radiator core
and charge air cooler core (diesel).
This can also cause corrosion of
these cores. Wash the radiator core
with tap water every 24 months.
Make sure to turn the engine off and
remove the key from the engine
control switch before cleaning
cores.
The engine, exhaust pipe, and
radiator will be hot immediately after
the vehicle is driven. Be careful
around these parts to prevent burns.
Clean the engine when it is cold.
Do not clean the radiator, charge air
cooler (diesel) and their surrounding
areas using water that is supplied
under high pressure. Doing so may
cause damage.
When cleaning the radiator core (1)
and charge air cooler core (2) , do
not crush or damage the fins (3).
The fins are very fragile so be
careful not to bend them out of
shape. If they become deformed,
their cooling efficiency will be
impaired. Before cleaning, take
steps to ensure that no water will
splash onto the surrounding
electrical components and wires.
If stubborn dirt still remains even
after the radiator core and charge
air cooler core (diesel) have been
cleaned, have the vehicle inspected
and serviced.
Corrosion Protection
Your vehicle has been designed and
built to resist corrosion. Special
materials and protective finishes
were used on most parts of your
vehicle when it was built to help
maintain good appearance,
strength, and reliable operation.
However, some parts which
normally are not visible (such as
those under the vehicle and under
the hood) are such that surface rust
will not affect their reliability. So
corrosion protection is not needed
or used on these parts.
Sheet Metal Damage
If your vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to the parts repaired or
replaced so that corrosion protection
is restored. (Also see "Finish
Damage" which follows.)
Foreign Material Deposits
Calcium chloride and other salts,
ice-melting agents, road oil and tar,
tree sap, bird droppings, chemicals
