Exterior Lamp Controls
The exterior lamp control is on the
instrument panel to the left of the steering
wheel.
There are four positions:
O: Briefly turn the control to this position
to turn the automatic headlamps and
Daytime Running Lamps (DRL) off or
back on.
For vehicles first sold in Canada, the off
position only works for vehicles that are
shifted into the P (Park) position.
AUTO : Automatically turns the exterior
lamps on and off, depending on outside
lighting.
;: Turns on the parking lamps including
all lamps, except the headlamps.
2: Turns on the headlamps together with
the parking lamps and instrument panel
lights.
If the headlamps are turned on while the
vehicle is on, the headlamps turn off
automatically 10 minutes after the ignition
is turned off. If the headlamps are turned on
while the vehicle is off, the headlamps will
continue to stay on. To prevent the battery
from being drained, turn the control to the
Oposition.
A warning chime sounds if the driver door is
opened while the ignition switch is off and
the headlamps are on.
To change the headlamps from low beam to
high beam, pull the turn signal lever all the
way toward you. Then release it.
Exterior Lamps Off Reminder
If a door is open, a reminder chime sounds
when the headlamps or parking lamps are
manually turned on and the key is out of
the ignition. To turn off the chime, turn the
headlamp switch to
Oor AUTO and then
back on, or close and re-open the door. In

Chevrolet Express Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

Lighting 93
The vehicle has a light sensor on the top of
the instrument panel. Do not cover the
sensor; otherwise the system will come on
whenever the ignition is on.
The system may also turn on the headlamps
when driving through a parking garage or
tunnel.
There is a delay in the transition between
the daytime and nighttime operation of the
Daytime Running Lamps (DRL) and the
automatic headlamp system so that driving
under bridges or bright overhead street
lights does not affect the system. The DRL
and automatic headlamp system are only
affected when the light sensor sees a
change in lighting lasting longer than the
delay.
If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. Once the vehicle leaves the
garage, it takes approximately 30 seconds
for the automatic headlamp system to
change to DRL if it is light outside. During
that delay, the instrument cluster may not
be as bright as usual. Make sure the
instrument panel brightness control is in the
full bright position. SeeInstrument Panel
Illumination Control 094. To idle the vehicle with the automatic
headlamp system off, turn the control off.
The headlamps will also stay on after
exiting the vehicle. This feature may be
programmable. See
Vehicle Personalization
0 87.
If the feature is not programmable, exit
lighting is automatic. When it is dark
enough outside, the exterior lamps remain
on for 30 seconds after the ignition is
turned off.
Lights On with Wipers
If the windshield wipers are activated in
daylight with the engine on, and the
exterior lamp control is in AUTO, the
headlamps, parking lamps, and other
exterior lamps come on. The transition time
for the lamps coming on varies based on
wiper speed. When the wipers are not
operating, these lamps turn off. Move the
exterior lamp control to
Por;to
disable this feature.
Hazard Warning Flashers
|: Press this button to make the front
and rear turn signal lamps flash on and off.
This warns others that you are having
trouble. Press again to turn the flashers off.
When the hazard warning flashers are on,
the vehicle's turn signals will not work.

124 Driving and Operating
.Ease your foot off the accelerator pedal
and steer the way you want the vehicle
to go. The vehicle may straighten out. Be
ready for a second skid if it occurs.
.Slow down and adjust your driving
according to weather conditions. Stopping
distance can be longer and vehicle control
can be affected when traction is reduced
by water, snow, ice, gravel, or other
material on the road. Learn to recognize
warning clues—such as enough water,
ice, or packed snow on the road to make
a mirrored surface —and slow down
when you have any doubt.
.Try to avoid sudden steering, acceleration,
or braking, including reducing vehicle
speed by shifting to a lower gear. Any
sudden changes could cause the tires to
slide.
Remember: Antilock brakes help avoid only
the braking skid.
Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop and
accelerate. Always drive slower in these
types of driving conditions and avoid driving
through large puddles and deep-standing or
flowing water.
{Warning
Wet brakes can cause crashes. They
might not work as well in a quick stop
and could cause pulling to one side. You
could lose control of the vehicle.
After driving through a large puddle of
water or a car/vehicle wash, lightly apply
the brake pedal until the brakes work
normally.
Flowing or rushing water creates strong
forces. Driving through flowing water
could cause the vehicle to be carried
away. If this happens, you and other
vehicle occupants could drown. Do not
ignore police warnings and be very
cautious about trying to drive through
flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can build
up under the vehicle's tires so they actually
ride on the water. This can happen if the
road is wet enough and you are going fast
enough. When the vehicle is hydroplaning, it
has little or no contact with the road. There is no hard and fast rule about
hydroplaning. The best advice is to slow
down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather
driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in
good shape.
.Keep the windshield washer fluid reservoir
filled.
.Have good tires with proper tread depth.
See
Tires 0203.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through mountains
is different than driving on flat or rolling
terrain. Tips include:
.Keep the vehicle serviced and in good
shape.
.Check all fluid levels and brakes, tires, and
cooling system.
.Shift to a lower gear when going down
steep or long hills.

126 Driving and Operating
Warning (Continued)
If the vehicle is stuck in snow:
.Clear snow from the base of the
vehicle, especially any blocking the
exhaust pipe.
.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 0136.
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 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.
The Traction Control System (TCS) can often
help to free a stuck vehicle. See
Traction
Control/Electronic Stability Control 0142.
If TCS cannot free the vehicle, turn TCS off
and use the rocking method. See “Rocking
the Vehicle to Get it Out” following.
{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
Transporting
a Disabled Vehicle 0231.
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.

6. Release the brake pedal.
See your dealer if the key can be removed
in any other position.
Retained Accessory Power (RAP) will remain
active. See Retained Accessory Power (RAP)
0 133.
A warning chime will sound when the driver
door is opened and the key is in the
ignition.
If equipped with a locking steering column,
the steering can bind with the front wheels
turned off center, which may prevent key
rotation out of LOCK/OFF. If this happens,
move the steering wheel from right to left
while turning the key to ACC/ACCESSORY.
If this does not work, then the vehicle needs
service.
{Warning
Turning off the vehicle while moving may
cause loss of power assist in the brake
and steering systems and disable the
airbags. While driving, turn off the
vehicle only in an emergency. In an emergency, if the vehicle cannot be
pulled over and must be turned off while
driving:
1. Push the key all the way in toward the steering column, then turn the key to
ACC/ACCESSORY.
2. Brake using firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
3. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
Continue braking and steer the vehicle to
a safe location.
4. Come to a complete stop.
5. Shift to P (Park).
6. Continue to hold the brake pedal, then set the parking brake. See Parking Brake
0 141.
7. Push the key all the way in toward the steering column, then turn the ignition
to LOCK/OFF.
8. Remove the key.
9. Release the brake pedal.
Caution
Use the correct key, make sure it is all
the way in —or pushed all the way in
toward the steering column when turning
off the vehicle —and turn it only with
your hand.
1 (ACC/ACCESSORY) : This position allows
features such as the infotainment system to
operate while the vehicle is off. It also
unlocks the steering column, if equipped
with a locking steering column. Use this
position if the vehicle must be pushed or
towed. See Retained Accessory Power (RAP)
0 133.
From ON/RUN, push the key all the way in
toward the steering column, then turn the
key to ACC/ACCESSORY.
If the key is left in ACC/ACCESSORY with the
engine off, the battery could drain and the
vehicle may not start.
A warning chime will sound when the driver
door is opened and the key is in the
ignition.
2 (ON/RUN) : This position can be used to
operate the electrical accessories and to
display some instrument cluster warning
and indicator lights. This position can also

132 Driving and Operating
be used for service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may be
required for emission inspection purposes.
The switch stays in this position when the
engine is running. The transmission is also
unlocked in this position.
If the key is left in ON/RUN with the engine
off, the battery could drain and the vehicle
may not start.
3 (START) :This is the position that starts
the engine. When the engine starts, release
the key. The ignition returns to ON/RUN for
driving.
Starting the Engine
To place the transmission in the
proper gear:
Move the shift lever to P (Park) or
N (Neutral). The engine will not start in any
other position. To restart the engine when
the vehicle is already moving, use
N (Neutral) only.
Caution
If you add electrical parts or accessories,
you could change the way the engine
operates. Any resulting damage would
not be covered by the vehicle warranty.
See Add-On Electrical Equipment 0171.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could
damage the transmission. Shift to P (Park)
only when the vehicle is stopped.
Caution
If the steering wheel is turned until it
reaches the end of its travel, and is held
in that position while starting the vehicle,
damage may occur to the hydraulic
power steering system and there may be
loss of power steering assist.
Starting Procedure 1. With your foot off the accelerator pedal, turn the ignition key to START. When
the engine starts, let go of the key. The
idle speed will go down as your engine gets warm. Do not race the engine
immediately after starting it. Operate
the engine and transmission gently to
allow the oil to warm up and lubricate
all moving parts.
When the low fuel warning light is on
and the FUEL LEVEL LOW message is
displayed in the Driver Information
Center (DIC), the Computer-Controlled
Cranking System is disabled to prevent
possible vehicle component damage.
When this happens, hold the ignition
switch in the START position to continue
engine cranking.
Caution
Cranking the engine for long periods of
time, by returning the ignition to the
START position immediately after
cranking has ended, can overheat and
damage the cranking motor, and drain
the battery. Wait at least 15 seconds
between each try, to let the cranking
motor cool down.
2. If the engine does not start after five to 10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try

Chevrolet Express Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16547501) - 2023 - CRC - 6/10/22
Driving and Operating 133
pushing the accelerator pedal all the way
to the floor and holding it there as you
hold the key in START for up to
15 seconds. Wait at least 15 seconds
between each try, to allow the cranking
motor to cool down. When the engine
starts, let go of the key and accelerator.
If the vehicle starts briefly but then
stops again, do the same thing. This
clears the extra gasoline from the
engine. Do not race the engine
immediately after starting it. Operate
the engine and transmission gently until
the oil warms up and lubricates all
moving parts.
Fast Idle System
If equipped, this feature is available only
with cruise control. The manual fast idle
switch is operated using the cruise control
buttons on the left side of the steering
wheel.
This system can be used to increase engine
idle speed whenever the following

Braking within the current ignition key cycle,
press and hold the Tow/Haul button for
three seconds.
See Towing Equipment 0167.
For other forms of grade braking, see
Automatic Transmission 0137.
Brakes
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.
ABS performs a system check when the
vehicle is first driven. A momentary motor
or clicking noise may be heard while this
test is going on, and the brake pedal may
move slightly. This is normal.
If there is a problem with ABS, this warning
light stays on. See Antilock Brake System
(ABS) Warning Light 079.
ABS does not change the time needed to
get a foot on the brake pedal and does not
always decrease stopping distance. If you
get too close to the vehicle ahead, there will
not be enough time to apply the brakes if
that vehicle suddenly slows or stops. Always
leave enough room ahead to stop, even
with ABS.
