Trip/Fuel Menu Items
3: Press this button to scroll
through the following menu items:
Odometer
Press
3until XX km (mi)
displays. This display shows the
distance the vehicle has been
driven in either kilometers (km) or
miles (mi). Trip Odometers
Press
3until A or B displays.
This display shows the current
distance traveled in either
kilometers (km) or miles (mi) since
the last reset for each trip odometer.
Both trip odometers can be used at
the same time.
Each trip odometer can be reset to
zero separately by pressing
Vwhile
the desired trip odometer is
displayed.
The trip odometer has a feature
called the retro-active reset. This
can be used to set the trip odometer
to the number of kilometers (miles)
driven since the ignition was last
turned on. This can be used if the
trip odometer is not reset at the
beginning of the trip.
To use the retro-active reset feature,
press and hold
Vfor at least
four seconds. The trip odometer will
display the number of
kilometers (km) or miles (mi) driven
since the ignition was last turned on
and the vehicle was moving. Once
the vehicle begins moving, the trip

Instruments and Controls 101
odometer will accumulate mileage.
For example, if the vehicle was
driven 8 km (5 miles) before it is
started again, and then the
retro-active reset feature is
activated, the display will show 8 km
(5 miles). As the vehicle begins
moving, the display will then
increase to 8.1 km (5.1 miles),
8.2 km (5.2 miles), etc.
If the retro-active reset feature is
activated after the vehicle is started,
but before it begins moving, the
display will show the number of
kilometers (km) or miles (mi) that
were driven during the last ignition
cycle.
Fuel Range
Press
3until FUEL RANGE
displays. This display shows the
approximate number of remaining
kilometers (km) or miles (mi) the
vehicle can be driven without
refueling.
The fuel range estimate is based on
an average of the fuel economy
over recent driving history and the
amount of fuel remaining in the fuel tank. This estimate will change if
driving conditions change. For
example, if driving in traffic and
making frequent stops, this display
may read one number, but if the
vehicle is driven on a freeway, the
number may change even though
the same amount of fuel is in the
fuel tank. This is because different
driving conditions produce different
fuel economies. Generally, freeway
driving produces better fuel
economy than city driving.
If the vehicle is low on fuel, the
FUEL LEVEL LOW message will be
displayed.
Average Economy
Press3until AVG ECONOMY
displays. This display shows the
approximate average liters per
100 kilometers (L/100 km) or miles
per gallon (mpg). This number is
calculated based on the number of
L/100 km (mpg) recorded since the
last time this menu item was reset.
To reset AVG ECONOMY, press and
hold
V. The display will return
to zero. Fuel Used
Press
3until FUEL USED
displays. This display shows the
number of liters (L) or gallons (gal)
of fuel used since the last reset of
this menu item. To reset the fuel
used information, press and hold
V
while FUEL USED is displayed.
Timer
Press
3until TIMER displays.
This display can be used as a timer.
To start the timer, press
Vwhile
TIMER is displayed. The display will
show the amount of time that has
passed since the timer was last
reset, not including time the ignition
is off. Time will continue to be
counted as long as the ignition is
on, even if another display is being
shown on the DIC. The timer will
record up to 99 hours, 59 minutes
and 59 seconds (99:59:59) after
which the display will return to zero.
To stop the timer, press
Vbriefly
while TIMER is displayed.
To reset the timer to zero, press and

Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible:
. Set the climate controls to the
desired temperature after the
engine is started, or turn them
off when not required.
. Avoid fast starts and accelerate
smoothly.
. Brake gradually and avoid
abrupt stops.
. Avoid idling the engine for long
periods of time.
. When road and weather
conditions are appropriate, use
cruise control.
. Always follow posted speed
limits or drive more slowly when
conditions require.
. Keep vehicle tires properly
inflated. .
Combine several trips into a
single trip.
. Replace the vehicle's tires with
the same TPC Spec number
molded into the tire's sidewall
near the size.
. Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms
and can take your focus from the
task of driving. Exercise good
judgment and do not let other
activities divert your attention away
from the road. Many local
governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, keep
your eyes on the road, keep your
hands on the steering wheel, and
focus your attention on driving.

Chevrolet Express Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13882570) - 2020 - CRC - 11/1/19
Driving and Operating 157
.Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0178.
. Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes
should be applied sooner than
when on dry pavement. See
Antilock Brake System (ABS)
0176.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
. Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside Assistance. See
Roadside
Assistance Program 0325. To get
help and keep everyone in the
vehicle safe:
. Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
. Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
(Continued)
Warning (Continued)
.Open a window about 5 cm
(2 in) on the vehicle side
that is away from the wind,
to bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.
. Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the highest
setting. See “Climate
Control Systems.”
For more information about CO,
see Engine Exhaust 0170.
To save fuel, run the engine for
short periods to warm the vehicle
and then shut the engine off and
partially close the window. Moving
about to keep warm also helps.
If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle

13882570) - 2020 - CRC - 11/1/19
158 Driving and Operating
speed. This keeps the battery
charged to restart the vehicle and to
signal for help with the headlamps.
Do this as little as possible, to
save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. SeeTraction
Control/Electronic Stability Control
0 178.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a low
forward gear, spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear.
Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out,
see Towing the Vehicle 0291.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on the vehicle may
show how much weight it was
designed to carry, the Tire and
Loading Information label and
the Certification/Tire label.
{Warning
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.
