Lighting Features
Entry Lighting
Some exterior lamps and the interiorlamps turn on briefly at night, or in
areas with limited lighting, whenK
is pressed on the Remote KeylessEntry (RKE) transmitter. When adoor is opened, the interior lampscome on if the dome lamp control isin the DOOR position. After about30 seconds the exterior lamps turnoff. Entry lighting can be disabledmanually by changing the ignitionout of the OFF position, or by
pressing the RKE transmitterQ
button.
This feature can be changed. See“Ve h i c l e L o c a t o r L i g h t s”underVehicle Personalization0160.
Exit Lighting
Some exterior lamps and the interiorlamps come on at night, or in areaswith limited lighting when the key isremoved from the ignition. Theexterior and interior lamps remainon for a set amount of time and then
automatically turn off. The interiorlamps do not come on if the domelamp control is in the Off position.
The exterior lamps turn offimmediately by turning the exteriorlamps control off.
This feature can be changed. SeeVehicle Personalization0160.
Battery Load
Management
The vehicle has Electric PowerManagement (EPM), whichestimates the battery's temperatureand state of charge. It then adjuststhe voltage for best performanceand extended life of the battery.
When the battery's state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.When the state of charge is high,the voltage is lowered slightly toprevent overcharging. The voltmetergauge or the voltage display on theDriver Information Center (DIC),if equipped, may show the voltage
moving up or down. This is normal.If there is a problem, an alert will bedisplayed.
The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles.This is because the generator(alternator) may not be spinning fastenough at idle to produce all thepower that is needed for very highelectrical loads.
Ahighelectricalloadoccurswhenseveral of the following are on, suchas: headlamps, high beams, foglamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.
EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.It can increase engine idle speed togenerate more power, wheneverneeded. It can temporarily reducethe power demands of someaccessories.

Driving and Operating 255
Traction is reduced on hard packedsnow and ice and it is easy to losecontrol. Reduce vehicle speed whendriving on hard packed snowand ice.
{Warning
Driving on frozen lakes, ponds,
or rivers can be dangerous. Ice
conditions vary greatly and the
vehicle could fall through the ice;
you and your passengers could
drown. Drive your vehicle on safe
surfaces only.
Driving in Water
{Warning
Driving through rushing water can
be dangerous. Deep water can
sweep your vehicle downstream
and you and your passengers
could drown. If it is only shallow
water, it can still wash away the
ground from under your tires.
(Continued)
Warning (Continued)
Traction could be lost, and the
vehicle could roll over. Do not
drive through rushing water.
Caution
Do not drive through standing
water if it is deep enough to cover
the wheel hubs, axles, or exhaust
pipe. Deep water can damage the
axle and other vehicle parts.
If the standing water is not too deep,drive slowly through it. At fasterspeeds, water splashes and thevehicle can stall. When goingthrough water, the brakes get wetand it may take longer to stop. See“Driving on Wet Roads”later in thissection.
After Off-Road Driving
Remove any brush or debris thathas collected on the underbody orchassis, or under the hood. Theseaccumulations can be a fire hazard.
After operation in mud or sand,have the brake linings cleaned andchecked. These substances cancause glazing and uneven braking.Check the body structure, steering,suspension, wheels, tires, andexhaust system for damage andcheck the fuel lines and coolingsystem for any leakage.
More frequent maintenance serviceis required. See theMaintenanceSchedule0452.
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.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-9956065) - 2017 - CRC - 4/29/16
256 Driving and Operating
{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. 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.
.Keep the windshield washer fluidreservoir filled.
.Have good tires with propertread depth. SeeTires0397.
.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.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-9956065) - 2017 - CRC - 4/29/16
282 Driving and Operating
If the vehicle has an exhaust brake,it can also be used, but will notautomatically downshift thetransmission. See“Exhaust Brake”in the Duramax diesel supplement.
Caution
Spinning the tires or holding the
vehicle in one place on a hill
using only the accelerator pedal
may damage the transmission.
The repair will not be covered by
the vehicle warranty. If you are
stuck, do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.
Low Traction Mode
If equipped, Low Traction Modeassists in vehicle acceleration whenroad conditions are slippery, suchas with ice or snow. While thevehicle is at a stop, select L2 usingRange Selection Mode. This willlimit torque to the wheels and helpto prevent the tires from spinning.
Tow/Haul Mode
Vehicles with an automatictransmission have a Tow/HaulMode. The Tow/Haul Mode adjuststhe transmission shift pattern toreduce shift cycling. This providesincreased performance, vehiclecontrol, and enhanced transmissionand engine cooling when drivingdown steep hills or mountaingrades, when towing, or whenhauling heavy loads.
The selector button is on the end ofthe shift lever. Turn the Tow/HaulMode on and off by pressing the
button. When the Tow/Haul Mode isenabled, a light on the instrumentcluster will come on.
For an eAssist vehicle, the Stop/Start function will becomeunavailable when Tow/Haul Mode isactive.
For an eAssist vehicle, theRegenerative Braking functionality isdisabled when using the Tow/HaulMode. See the eAssist supplement.
