Warning (Continued)
down a slope without the engine
running, you would not be able to
properly control the vehicle and
could have an accident.
Parking, or Leaving
Driver’s Seat
{Danger
It can be dangerous to get out of
your vehicle if the selector lever is
not fully in "P" (Park) or the
parking brake is not applied all
the way. Your vehicle can roll or
move suddenly.
To be sure your vehicle will not
move, even when you are parking
on level ground, follow the steps
below. (If you have to park on a
hill, also turn your front wheels so
the vehicle will roll away from
traffic.)
You and others could be seriously
injured or killed. 1. Hold the regular brake pedal
down with your right foot and
apply the parking brake all the
way before shifting the
transmission. Follow the
Parking Brake instructions in
this manual for your vehicle.
2. To move the selector lever to "P" (Park), hold in the button
on the lever and push the lever
all the way toward the front of
your vehicle.
3. Turn the key to "LOCK".
4. Remove the key and take it with you.
5. Before you leave the driver's seat, be sure the vehicle is not
moving, or check that your
vehicle is in Park by trying to
pull the selector lever out of "P"
(Park) by pulling the selector
lever toward you without
pushing the button. If you can
do this, it means that the
selector lever was not fully
locked into "P" (Park). Do Not Touch the Selector Lever
While the Vehicle is Stationary
with the Engine Idling
(Gasoline Only)
(Diesel) Do not touch the selector
lever while the vehicle is stationary
with the engine idling. If you touch
the selector lever at this time, a gear
could be selected and the vehicle
could move even with the parking
brake applied. The risk of knocking
against the selector lever and
causing an accident is particularly
great when you move in or out of
your seat.
Driving Down a Long Slope
When driving down a long slope,
use the exhaust brake (diesel) or
engine brake (gasoline) together
with the foot brakes. Using the
exhaust brake (diesel) or engine
brake (gasoline) and low-gears
reduces the work load on the foot
brakes and yields greater braking
force. Even so, use the foot brakes
appropriately to prevent the engine
over-revving.

146 Driving and Operating
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.

2,300 r/min.
Mechanical Driveshaft Brake
Burnish Procedure
It is recommended that the
driveshaft mounted parking brake
be burnished as part of the new
vehicle break-in procedure.
Increased parking brake
performance will result when the
parking brake is burnished as
specified below:
. Make 10 moderate stops, using
the hand brake, from 16 km/h
(10 MPH) while spacing the
stops a minimum of 4 km
(2.5 miles) apart. .
Operate the vehicle at 32 km/h
(20 MPH) between stops.
Pedals
Sit in a correct driving position on
the seat and operate the brake
pedal (1) and accelerator pedal (2)
with your right foot. To avoid
accidentally pressing the wrong
pedal, check the pedal positions
and practice putting your foot on the
desired pedal.
{Warning
A can or bottle rolling on the floor
may prevent brake pedal
operation if it is caught under the
pedal. This is very dangerous.
A floor mat must be placed
correctly. An incorrectly installed
floor mat may hinder the free
movement of each pedal. You
and others could be seriously
injured.
Ignition Positions
Engine Control Switch

engine. See
Seat Position 044,
Seat Belts 049, Steering Wheel
Adjustment 072, and Mirrors039.
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. (Continued)
Warning (Continued)
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

Chevrolet Low Cab Forward Owner Manual (GMNA-Localizing-U.S.-
10716700) - 2017 - crc - 12/6/16
Driving and Operating 167
feature. To restart when you're
already moving, use
N (Neutral) only.
Do not try to shift to P (Park) if
your vehicle is moving. If you
do, you could damage the
transmission. Shift to P (Park)
only when your vehicle is
stopped.
2. Do not push the accelerator pedal before starting your
engine. In some other vehicles
you might need to do this, but
because of your vehicle's
computer systems, you do not
need to.
3. Turn your ignition key to Start. When the engine starts, let go
of the key. The idle speed will
go down as your engine
gets warm.
4. If it does not start right away, hold your key in START. If it
doesn't start in 3 seconds,
push the accelerator pedal
about one-quarter of the way
down for 12 more seconds,
or until it starts. 5. If your engine still will not start
(or starts but then stops), it
could be flooded with too much
gasoline. Try this: Wait 20 to
30 seconds to let the starter
motor cool down. Then push
your accelerator pedal all the
way to the floor. Hold it there.
Then, hold the key in START
for no more than 10 seconds.
This clears the extra gasoline
from the engine.
If the engine still does not start, wait
another 20 to 30 seconds and do
Step 5 again.
Hot Engine Restart
If your engine is already hot and
then stalls, turn your ignition key to
ACC. Then, turn your key to ON,
and wait about 20 to 30 seconds
before you restart your engine.
When the engine starts, let go of the
key and the accelerator pedal.
Your engine is designed to work
with the electronics in your vehicle.
If you add electrical parts or
accessories, you could change the
way the fuel injection system operates. Before adding electrical
equipment, check with your dealer.
If you do not, your engine might not
perform properly.
If you ever have to have your
vehicle towed, see the part of this
manual that tells how to do it without
damaging your vehicle. See
Towing
the Vehicle 0332.
Recommendations for Warming
Up the Engine
The engine is sufficiently warmed
up when the needle of the engine
coolant temperature gauge starts
to move.
. Do not race the engine or
quickly accelerate before the
engine has sufficiently warmed
up. Oil would not have
adequately reached and
lubricated components, and a
breakdown may result.
. The exhaust pipe becomes
extremely hot while the engine is
idling. Before warming up the
engine, make sure there is no
