166 Driving and Operating
Drunk Driving
Death and injury associated withdrinking and driving is a globaltragedy.
{Warning
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
asmallamountofalcohol.You
can have a serious—or even
fatal—collision if you drive after
drinking.
Do not drink and drive or ride with
adriverwhohasbeendrinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Control of a Vehicle
Braking, steering, and acceleratingare important factors in helping tocontrol a vehicle while driving.
Braking
Braking action involves perceptiontime and reaction time. Deciding topush the brake pedal is perceptiontime. Actually doing it isreaction time.
Average driver reaction time isabout three-quarters of a second. Inthat time, a vehicle moving at100 km/h (60 mph) travels 20 m(66 ft), which could be a lot ofdistance in an emergency.
Helpful braking tips to keep in mindinclude:
.Keep enough distance betweenyou and the vehicle in frontof you.
.Avoid needless heavy braking.
.Keep pace with traffic.
If the engine ever stops while thevehicle is being driven, brakenormally but do not pump thebrakes. Doing so could make thepedal harder to push down. If theengine stops, there will be somepower brake assist but it will beused when the brake is applied.
Once the power assist is used up, itcan take longer to stop and thebrake pedal will be harder to push.
Steering
Hydraulic Power Steering
Yo u r v e h i c l e h a s h y d r a u l i c p o w e rsteering. It may requiremaintenance. SeePower SteeringFluid0232.
If power steering assist is lostbecause the engine stops orbecause of a system malfunction,the vehicle can be steered but mayrequired increased effort. See yourdealer if there is a problem.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
for more than 15 seconds,
damage may occur to the power
steering system and there may be
loss of power steering assist.

Curve Tips
.Ta k e c u r v e s a t a r e a s o n a b l espeed.
.Reduce speed before entering acurve.
.Maintain a reasonable steadyspeed through the curve
.Wait until the vehicle is out ofthe curve before acceleratinggently into the straightaway.
Steering in Emergencies
.There are some situations whensteering around a problem maybe more effective than braking.
.Holding both sides of thesteering wheel allows you to turn180 degrees without removingahand.
.Antilock Brake System (ABS)allows steering while braking.
Off-Road Recovery
The vehicle's right wheels can dropoff the edge of a road onto theshoulder while driving. Followthese tips:
1. Ease off the accelerator andthen, if there is nothing in theway, steer the vehicle so that itstraddles the edge of thepavement.
2. Turn the steering wheel aboutone-eighth of a turn, until theright front tire contacts thepavement edge.
3. Turn the steering wheel to gostraight down the roadway.
Loss of Control
Skidding
There are three types of skids thatcorrespond to the vehicle's threecontrol systems:
.Braking Skid—wheels are notrolling.
.Steering or Cornering Skid—too much speed or steering in acurve causes tires to slip andlose cornering force.
.Acceleration Skid—too muchthrottle causes the drivingwheels to spin.
Defensive drivers avoid most skidsby taking reasonable care suited toexisting conditions, and by notoverdriving those conditions. Butskids are always possible.
If the vehicle starts to slide, followthese suggestions:
.Ease your foot off theaccelerator pedal and steer theway you want the vehicle to go.

168 Driving and Operating
The vehicle may straighten out.Be ready for a second skid if itoccurs.
.Slow down and adjust yourdriving according to weatherconditions. Stopping distancecan be longer and vehiclecontrol can be affected whentraction is reduced by water,snow, ice, gravel, or othermaterial on the road. Learn torecognize warning clues—suchas enough water, ice, or packedsnow on the road to make amirrored surface—and slowdown when you have any doubt.
.Try to avoid sudden steering,acceleration, or braking,including reducing vehicle speedby shifting to a lower gear. Anysudden changes could causethe tires to slide.
Remember: Antilock brakes helpavoid only the braking skid.
Driving on Wet Roads
Rain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep-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
(Continued)
Warning (Continued)
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Watercan build up under the vehicle'stires so they actually ride on thewater. This can happen if the road iswet enough and you are going fastenough. When the vehicle ishydroplaning, it has little or nocontact with the road.
There is no hard and fast rule abouthydroplaning. The best advice is toslow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wetweather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wipingequipment in good shape.

Chevrolet Express Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-9967827) - 2017 - crc - 5/6/16
Driving and Operating 169
.Keep the windshield washer fluidreservoir filled.
.Have good tires with propertread depth. SeeTires0252.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips include:
.Keep the vehicle serviced and ingood shape.
.Check all fluid levels and brakes,tires, cooling system, andtransmission.
.Shift to a lower gear when goingdown steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
(Continued)
Warning (Continued)
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.
.Drive at speeds that keep thevehicle in its own lane. Do notswing wide or cross thecenter line.
.Be alert on top of hills;something could be in your lane(e.g., stalled car, accident).
.Pay attention to special roadsigns (e.g., falling rocks area,winding roads, long grades,passing or no-passing zones)and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires andthe road creates less traction orgrip, so drive carefully. Wet ice canoccur at about 0 °C (32 °F) whenfreezing rain begins to fall. Avoiddriving on wet ice or in freezing rainuntil roads can be treated.
For slippery road driving:
.Accelerate gently. Acceleratingtoo quickly causes the wheels tospin and makes the surfaceunder the tires slick.
.Turn on Traction Control. SeeTr a c t i o n C o n t r o l / E l e c t r o n i cStability Control0190.
.Antilock Brake System (ABS)improves vehicle stability duringhard stops, but the brakesshould be applied sooner than

Chevrolet Express Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-9967827) - 2017 - crc - 5/6/16
170 Driving and Operating
when on dry pavement. SeeAntilock Brake System(ABS)0188.
.Allow greater following distanceand watch for slippery spots. Icypatches can occur on otherwiseclear roads in shaded areas.The surface of a curve or anoverpass can remain icy whenthe surrounding roads are clear.Avoid sudden steeringmaneuvers and braking whileon ice.
.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place andsignal for help. Stay with the vehicleunless there is help nearby.If possible, use RoadsideAssistance. SeeRoadsideAssistance Program0316.Togethelp and keep everyone in thevehicle safe:
.Turn on the hazard warningflashers.
.Tie a red cloth to an outsidemirror.
{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 ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set

the fan speed to the highestsetting. See“ClimateControl Systems.”
For more information about CO,
seeEngine Exhaust0182.
To s a v e f u e l , r u n t h e e n g i n e f o rshort periods to warm the vehicleand then shut the engine off andpartially close the window. Movingabout to keep warm also helps.
If it takes time for help to arrive,when running the engine, push theaccelerator pedal slightly so theengine runs faster than the idlespeed. This keeps the batterycharged to restart the vehicle and tosignal for help with the headlamps.Do this as little as possible, tosave fuel.
