Be careful not to inadvertently
touch them when working near
them (for example, tilting the cab
or operating an attachment). You
and others could be seriously
injured.
Recommendations for Driving
in Hot Regions
The engine is more likely to
overheat in an environment where
the ambient temperature is high. To
prevent the engine from
overheating, pay attention to the
following points:
.If the engine does not contain
the appropriate concentration of
engine coolant, overheating is
likely to occur.
Refer to Engine Coolant 0263.
. Do not put well water, river water
or other hard water in the engine
cooling system. It would hasten
the formation of rust and scale. .
If foreign matter (insects, mud,
etc.) gets stuck in the radiator's
air passages, the cooling
system's performance will
deteriorate. Check the air
passages for clogging, and
remove any foreign matter using
water under low pressure.
Refer to Exterior Care 0334.
When Turning, the Rear
Wheels will Follow Tighter
Curves than the Front Wheels
Use the mirrors to confirm safety.
Sidewinds
If the vehicle catches a sidewind
and drifts sideways, firmly grip the
steering wheel, decelerate to a
speed that allows you to stay
completely in control, and make a
directional correction. The vehicle
may catch strong sidewinds in the
following situations:
.
Emerging from a tunnel
. Driving over a bridge
. Driving on an embankment
. Driving through a cutting .
Being overtaken by a large truck
or bus
. Overtaking a large truck or bus
Flat Tire
If a blowout or flat tire occurs while
you are driving, calmly grip the
steering wheel and gradually apply
the brakes to decelerate. (Hard
braking would be dangerous
because it could cause the steering
wheel to be pulled to one side.)
Stop the vehicle in a safe place, and
change the tire.
Hard Bump Under Vehicle
If the underside of the vehicle
receives a hard bump, stop in a safe
place where the vehicle will not
obstruct traffic and check for brake
fluid leakage, fuel leakage and
component damage. If any part of
the vehicle is damaged or broken,
promptly have the vehicle inspected
and repaired.
Highways
.Speeds on highways are higher
than those on regular roads, so
there is more danger. Also, a

10716700) - 2017 - crc - 12/6/16
Driving and Operating 137
breakdown on a highway
represents a hazard to other
vehicles and can cause an
accident. Concentrate on safe
driving. Remember to perform
daily pre-operation inspections
and use highway driving
techniques. When performing
daily pre-operation inspections,
perform the checks shown in the
table on the left with particularly
great care.
Refer toOwner Checks and
Services 0367.
. When merging with traffic on a
highway, use the turn signal
lights to indicate your intentions
ahead of time. Speed up
sufficiently when you are in the
acceleration lane. Pay attention
to vehicles behind you and to
conditions in the lane you are
joining. Merge in such a way that
you do not obstruct vehicles in
the lane.
. Your sense of how fast you are
traveling becomes distorted on
long highway drives. Constantly keep an eye on the
speedometer, and maintain a
suitable headway distance.
. During high-speed driving, even
a little turn of the steering wheel
causes a big movement of the
vehicle. Turn the steering wheel
slowly.
. Excessive use of the brake
pedal is extremely dangerous
because it rapidly wears the
brake linings and causes brake
fade. Make effective use of the
engine brake and the exhaust
brake when you want to
decelerate.
. When you want to turn off a
highway, use the turn signal
lights to indicate your intentions
ahead of time. Paying attention
to vehicles behind you, turn off
the highway smoothly so as not
to obstruct other vehicles.
Brake Fade : Frequent use of the
brakes can cause the brakes to
overheat so that the frictional force
of the brake linings decreases and the brakes become less effective
than normal. This phenomenon is
called brake fade.
Braking
Brake Operation
The brakes give strong braking
force with only light pressure on the
pedal. Do not press the brake pedal
hard except in the event of an
emergency.
Actual stopping distances vary
greatly. Your ability to stop safely
will be greatly affected by the
surface of the road, whether it is
pavement or gravel; the condition of
the road, whether it is wet, dry or
icy; tire tread; the condition of the
brakes; the weight of the vehicle;
the weight of the load; and the
amount of brake force applied.
Please allow for realistic stopping
distances to avoid unnecessary
heavy braking. That means better
braking, longer brake life and safer
driving.

Caution (Continued)
warning light comes on during
operation, have brake system
checked immediately.
Refer to Warning Lights, Gauges,
and Indicators 076.
When the Brakes Do Not Work
{Warning
It is very dangerous to suddenly
pull the parking brake lever all the
way while moving at high speed.
Reduce speed first by shifting
down and then gradually pull the
parking brake lever.
You and others could be seriously
injured.
(Diesel Only) The exhaust brake
should be turned on as soon as
service brake malfunction is
detected. This will slow the engine
speed. With the engine speed under
control and providing the grade conditions permit, the transmission
can be progressively downshifted
using the exhaust brake in each
gear. Eventually the exhaust brake
should slow the vehicle to a
controllable
“crawl.”Gradually pull
the parking brake lever while firmly
holding on to the steering wheel.
Stop the vehicle on the side of the
road. The vehicle should not be
driven further until corrective
measures are taken.
See Exhaust Brake (Diesel Only)
0 222 andParking Brake 0221.
(Gasoline Only) If the brakes do not
work in an unexpected situation,
promptly shift down from D6, D4,
2nd and then to 1st gear using the
selector lever to reduce the speed
and gradually pull the parking brake
lever to stop the vehicle on the side
of the road while firmly holding on to
the steering wheel.
See Parking Brake 0221. Riding the Brake
{Warning
"Riding the brake" by resting your
foot on the pedal, when you do
not intend to brake, can overheat
the brakes and wear out the
brake linings faster. This may also
damage the brakes and will waste
fuel. It can also result in reduced
braking performance.
You and others could be seriously
injured.
Applying the Parking Brake
Except in an emergency, do not
apply the parking brake until the
vehicle has come to a complete
stop. Applying the parking brake
before the vehicle has stopped can
cause a breakdown.
Refer to
Parking Brake 0221.
Parking Safely on a Slope
Avoid parking your vehicle on a
slope as much as possible and
choose a level and flat place. If you

Chevrolet Low Cab Forward Owner Manual (GMNA-Localizing-U.S.-
10716700) - 2017 - crc - 12/6/16
140 Driving and Operating
must park your vehicle on a slope,
be sure to set the parking brake
fully. Make sure that the vehicle
does not move, and block the
wheels with chocks for added
safety. Also, leave the vehicle in
gear to further ensure that it will not
move. Leave the steering wheel
turned such that the vehicle will be
stopped by an obstruction (for
example, the curb) in the unlikely
event that it moves.
Stopping and Parking with the
Engine Running
{Warning
When parking with the engine
running, first come to a complete
stop, then firmly apply the parking
brake, then move the selector
lever to the "P" (Park) position.
Unless you take these steps, any
unintended pressure on the
accelerator pedal could cause an
accident.(Continued)
Warning (Continued)
To reduce the chance of personal
injury and/or vehicle damage due
to engine overheating, never
leave the engine idling without an
alert driver present. If the engine
should overheat, as indicated by
the engine coolant temperature
gauge, immediate action is
required to correct the condition.
Continued operation of the
engine, even for a short time, may
result in a fire. Do not engage the
exhaust brake while the engine is
idling as this may cause engine
overheating.
The diesel particulate filter (DPF)
may automatically start
regeneration when the vehicle is
stopped and parked with the
engine running. To prevent a fire,
make sure there is no flammable
material near the muffler, DPF,
and exhaust pipe. Be careful not
to get burned by hot exhaust
gases.(Continued)
Warning (Continued)
You and others could be seriously
injured.
Do Not Forget to Release the
Parking Brake
Pulling away with the parking brake
still applied can damage the brake
system.
Before pulling away, make sure the
parking brake is not set by checking
that the parking brake indicator light
is not on.
Be Sure to Have the Engine
Running When the Vehicle is
Moving
{Warning
When the engine is not running,
the power steering system does
not work so the steering wheel is
hard to turn. Also, the brake
booster does not work so there is
little braking ability. If you coast (Continued)

Warning (Continued)
personal injury. Before parking
the vehicle in winter, press the
brake pedal several times in the
same way to get rid of moisture in
the brakes. Otherwise, the
moisture in the brakes may freeze
and make the vehicle immovable.
You and others could be seriously
injured.
If the vehicle must be driven on a
flooded road or is parked in an area
that becomes flooded, promptly
perform a check for the following
points:
. Effectiveness of the brakes
. Water-ingress or damage to
drum brakes, disc brakes
. Engine damage due to
water-ingress
. Shorting of electrical
components .
Oil level and degradation
(cloudiness) of the engine,
transmission, differential
. Greasing of each components
(lubrication)
Steering
Do Not Leave the Steering
Wheel Fully Turned for a
Long Time
{Warning
If you leave the steering wheel
fully turned for a long time, the oil
in the power steering oil pump will
become extremely hot. This
would cause poor lubrication, oil
tank damage and seal
deterioration, leading to power
steering oil pump damage, power
steering unit damage and power
steering hose damage. As a
result the steering wheel could
become extremely hard to turn
and a fire or other accident could
occur.
(Continued)
Warning (Continued)
You and others could be seriously
injured.
Steering Wheel
If the steering parts have excess
play or looseness or if any abnormal
condition is noted, have the steering
system checked immediately.
Driving on Wet Roads
Driving on Slippery Surface or
Driving in Bad Weather (Rain,
Icy Roads, Snowy Roads, etc.)
In bad weather, visibility is reduced
and slippery road surfaces increase
stopping distances. Drive more
slowly than you would in good
weather. Also, avoid sharp turns of
the steering wheel and hard
braking. Use engine brakes together
with the foot brakes to decelerate.
For diesel vehicles, using the
exhaust brake on a slippery road
surface could cause the tires to slip.

Chevrolet Low Cab Forward Owner Manual (GMNA-Localizing-U.S.-
10716700) - 2017 - crc - 12/6/16
144 Driving and Operating
You may not realize the surface is
slippery until the vehicle is skidding.
Learn to recognize warning clues—
such as enough water or ice on the
road to make a "mirrored surface"—
and slow down when there is any
doubt.
There is a risk of hydroplaning,
particularly where water tends to
collect on the road surface. Drive at
speeds that allow you to stay in
complete control.
If you cannot avoid driving on a
flooded road, first check the depth
of the water and then drive through
the water at a slow, constant speed.
There is a risk that water will get
into the engine's cylinders and
cause engine damage (water
hammering). Keep your speed
down, and drive with great care.
Hydroplaning :If a vehicle is driven
at high speed on a road that is
covered with water, a layer of water
can form between the tires and road
surface, causing the tires to lose
their grip and slide across the water.
This phenomenon is called hydroplaning. It is dangerous
because it makes the steering
wheel and brakes useless.
Refer to
Wheels and Tires 0308.
Hill and Mountain Roads
Narrow or Congested Roads
When passing or overtaking a
vehicle on a narrow mountain road
or on a narrow or congested urban
road, pay careful attention to
obstacles on either side and to the
condition of the shoulder of
the road.
When turning, the rear wheels will
follow tighter curves than the front
wheels. Use the mirrors to confirm
safety.
Driving Uphill or Downhill
Downshifts are performed for two
main purposes:
.
For engine braking on a steep
and/or long downward slope
. For responsiveness and
economy on an uphill slope

When Ice Prevents You from
Putting Your Key in the Door
or Opening the Door
If you try to force the key into the
door, you could bend it. And if you
try to pull the door open with undue
force, the rubber seal around the
door could come unstuck or become
damaged. Use warm water to melt
the ice, then quickly wipe it away
and open the door.
If the wipers, electric door mirrors,
or power windows freeze up, also
use warm water to melt the ice and
then operate the system. Otherwise,
you could damage the mechanism
and drain the battery. After that,
wipe the water away.
Before Driving in Cold Regions
Getting In and Out of the Vehicle
The step can get icy in cold regions.
Be careful not to slip when getting in
and out of the vehicle.
Before Sitting in the Driver’s Seat
Remove snow and ice from your
shoes when getting into the vehicle.
If you try to drive with snow on your shoes, your shoes would slip on the
pedals and you would not be able to
press the pedals properly, meaning
that your driving would be
inconsistent. Also, the cabin could
become more humid, causing the
glass to fog up.
Check Fuel Level
Fuel consumption increases when
tire chains are used. Determine how
much fuel you need to reach your
destination and fill up the tank in
advance. Refer to
Fuel for Diesel
Engines 0232 orFuel (Gasoline)
0 231.
Removing Snow from Glass
and Underbody
Do not use a sharp implement to
remove snow. Sharp edges could
damage rubber parts.
To maintain an adequate field of
view, use a plastic scraper to
remove snow and frost from the
glass surfaces. By using a plastic
scraper, you can remove the snow
and frost without scratching the glass. At this time, check whether
the wiper blades are frozen onto the
glass.
Also, look under the vehicle and
remove any lumps of ice that are
stuck to the underbody. Be careful
not to damage components.
Driving on Snowy or Frozen
Roads
On slippery roads, never accelerate
rapidly, brake hard, decelerate
rapidly or make sharp turns of the
steering wheel.
There is a risk of reduced grip
between the tires and road surface
and of increased braking distances.
The danger of icy road surfaces is
particularly great on bridges, in
shady places and where there are
puddles.
Keep your speed down and be sure
to use tire chains or winter tires on
snowy or frozen road surfaces.
For diesel vehicles, use engine
brakes together with the foot brakes
to decelerate. Using the exhaust
brake on a slippery road surface
could cause the tires to slip.

10716700) - 2017 - crc - 12/6/16
Driving and Operating 147
For gasoline vehicles, use lower
gears to overcome the retardation
effect of the engine. Apply the foot
brakes lightly.
Pay Attention to the Way the
Steering Wheel Turns and Feels
On snowy roads, water and snow
splashed up by the tires can freeze
and accumulate inside the fenders,
making the steering wheel hard to
turn. From time to time, get out of
the vehicle and remove any
accumulated snow.
Check the Brakes from Time
to Time
When the vehicle is driven or
parked on a snowy surface, ice can
form on the brakes, decreasing their
effectiveness. From time to time
while you are driving, press the
brake pedal lightly and check the
effectiveness of the brakes. Pay
attention to vehicles both ahead of
and behind you when checking the
brakes in this way.
Also, check the effectiveness of the
brakes as soon as possible when
starting to drive the vehicle after ithas been parked. If the brakes do
not work well, drive slowly and
gently press the brake pedal several
times until the brakes dry out and
start working normally.
Parking in Cold Regions
When snow collects around the
wheels and the lights, try to remove
it before night falls.
Do not apply the parking brake in
extremely cold weather, such as in
temperatures or at below 0 °C (32 °
F). If you leave the parking brake
applied, the wires and brake shoes
could freeze up, making it
impossible for you to release the
parking brake. Be sure to park the
vehicle in gear.
Be sure to put chocks against the
tires.
Whenever possible, park in a
garage to help prevent parts from
freezing up and to help make the
engine easy to start.
{Warning
If you park in a place where there
is a lot of snowfall, snow
accumulating around the vehicle
could limit ventilation. Running
the engine with the vehicle in
these conditions could cause
exhaust gases to enter the cabin,
resulting in carbon monoxide
poisoning. Take preventive action
by, for example, clearing the snow
around the vehicle.
You and others could be seriously
injured.
Do not park under trees or under
the eaves of a building. Chunks of
ice could fall on the vehicle if you
park in such a place.
Cleaning the Vehicle after
Driving on Snowy Roads
. The vehicle speed sensors are
fitted on the wheels. When
removing snow, ice, and other
incrustation, take great care not
to damage the components.

.Do not use a sharp implement to
remove snow. Sharp edges
could damage rubber parts.
Refer to Antilock Brake System
(ABS) 0217.
Remove snow that has stuck to the
inside of the fenders and to the
brake hoses. Otherwise, it may
damage components. After driving
on a salted road, wash the
underside of the vehicle as soon as
possible to prevent the salt from
causing rust. Spraying water under
high pressure is an effective way to
get the salt off.
After washing the vehicle, wipe the
door openings dry.
If the Vehicle Is Stuck
When Driving on Bad Roads
Freeing the Vehicle from Sand,
Mud, Snow, and Ice
If your vehicle gets stuck in sand,
mud, snow or ice, move the selector
lever from "Second" to "Reverse".
Apply a light pressure to the
accelerator pedal while the
transmission is in gear. Remove your foot from the accelerator and
press the brake pedal while shifting.
Do not race the engine. For best
traction, avoid spinning the wheels.
When you cannot avoid driving
through deep mud, using tire chains
is an effective way to avoid getting
stuck.
Do not allow wheels to spin freely in
mud, sand, snow, ice or other poor
road conditions. This free spinning
will damage the rear axle. Even
vehicles equipped with LSD (Limited
Slip Differential) have traction
limitations. If your vehicle gets stuck
and it is difficult to extricate,
immediately stop driving and have
the vehicle towed. Spinning wheels
for an extended period of time may
cause abnormal noises or
malfunction to LSD.
Do not spin wheels faster than
32 km/h (20 MPH). Damage may
result from excessive wheel
spinning, including tire, transmission
and/or rear axle malfunction.
When driving in sand or mud, avoid
hard braking, sudden acceleration
and sharp turns of the steering
wheel. Such actions could get the
vehicle stuck and make it difficult to
extricate.
After driving through deep mud: any
mud stuck to the vehicle can harm
the steering, brakes and powertrain.
Wash the vehicle and remove all
mud and other incrustation.
The vehicle speed sensors are fitted
on the wheels. When removing mud
and other incrustation, take great
care not to damage the
components.
Do not use a sharp implement to
remove mud. Sharp edges could
damage rubber parts.
