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.
Off-Road Driving
Four-wheel-drive vehicles can beused for off-road driving. Vehicleswithout four-wheel drive and
vehicles not equipped with AllTe r r a i n ( AT ) o r O n - O f f R o a d ( O O R )tires must not be driven off-roadexcept on a level, solid surface. Forcontact information about theoriginal equipment tires, see thewarranty manual.
One of the best ways for successfuloff-road driving is to control thespeed.
{Warning
When driving off-road, bouncing
and quick changes in direction
can easily throw you out of
position. This could cause you to
lose control and crash. You and
your passengers should always
wear safety belts.
Before Driving Off-Road
.Have all necessary maintenanceand service work completed.
.Fuel the vehicle, fill fluid levels,and check inflation pressure inall tires, including the spare,if equipped.
.Read all the information aboutfour-wheel-drive vehicles in thismanual.
.Remove any underbody airdeflector, if equipped. Re-attachthe air deflector after off-roaddriving.
.SeeHill Descent Control(HDC)0297
.Know the local laws that apply tooff-road driving.
To g a i n m o r e g r o u n d c l e a r a n c e i fneeded, it may be necessary toremove the front fascia lower airdam. However, driving without theair dam reduces fuel economy.
Caution
Operating the vehicle for
extended periods without the front
fascia lower air dam installed can
cause improper airflow to the
engine. Reattach the front fascia
air dam after off-road driving.

406 Vehicle Care
Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can
result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire
inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity.
For additional information
regarding how much weight the
vehicle can carry, and an
example of the Tire and Loading
Information label, seeVehicle
Load Limits0259.Howthe
vehicle is loaded affects vehicle
handling and ride comfort. Never
load the vehicle with more
weight than it was designed to
carry.
When to Check
Check the tires once a month
or more.
Do not forget the spare tire,
if the vehicle has one. See
Full-Size Spare Tire0431for
additional information.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-9956065) - 2017 - CRC - 4/29/16
Vehicle Care 407
inflation pressure is high, press
on the metal stem in the center
of the tire valve to release air.
Re-check the tire pressure with
the tire gauge.
Put the valve caps back on the
valve stems to keep out dirt and
moisture and prevent leaks. Use
only valve caps designed for the
vehicle by GM. TPMS sensors
could be damaged and would
not be covered by the vehicle
warranty.
Tire Pressure for
High-Speed Operation
{Warning
Driving at high speeds, 160 km/h
(100 mph) or higher, puts
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
This could cause a crash, and
(Continued)
Warning (Continued)
you or others could be killed.
Some high-speed rated tires
require inflation pressure
adjustment for high-speed
operation. When speed limits and
road conditions allow the vehicle
to be driven at high speeds, make
sure the tires are rated for
high-speed operation, are in
excellent condition, and are set to
the correct cold tire inflation
pressure for the vehicle load.
Vehicles with P275/55R20 orP285/50R20 size tires requireinflation pressure adjustment whendriving the vehicle at speeds of160 km/h (100 mph) or higher. Setthe cold tire inflation pressure to20 kPa (3 psi) above therecommended cold tire pressureshown on the Tire and LoadingInformation label.
Return the tires to therecommended cold tire inflationpressure when high-speed drivinghas ended. SeeVehicle Load Limits0259andTire Pressure0405.
Tire Pressure Monitor
System
The Tire Pressure Monitor System(TPMS) uses radio and sensortechnology to check tire pressurelevels. The TPMS sensors monitorthe air pressure in your tires andtransmit tire pressure readings to areceiver located in the vehicle.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommendedby the vehicle manufacturer on thevehicle placard or tire inflationpressure label. (If your vehicle hastires of a different size than the sizeindicated on the vehicle placard ortire inflation pressure label, youshould determine the proper tireinflation pressure for those tires.)

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-9956065) - 2017 - CRC - 4/29/16
408 Vehicle Care
As an added safety feature, yourvehicle has been equipped with atire pressure monitoring system(TPMS) that illuminates a low tirepressure telltale when one or moreof your tires is significantlyunder-inflated.
Accordingly, when the low tirepressure telltale illuminates, youshould stop and check your tires assoon as possible, and inflate themto the proper pressure. Driving on asignificantly under-inflated tirecauses the tire to overheat and canlead to tire failure. Under-inflationalso reduces fuel efficiency and tiretread life, and may affect thevehicle's handling and stoppingability.
Please note that the TPMS is not asubstitute for proper tiremaintenance, and it is the driver'sresponsibility to maintain correct tirepressure, even if under-inflation hasnot reached the level to triggerillumination of the TPMS low tirepressure telltale.
Yo u r v e h i c l e h a s a l s o b e e nequipped with a TPMS malfunctionindicator to indicate when thesystem is not operating properly.The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and thenremain continuously illuminated.This sequence will continue uponsubsequent vehicle start-ups aslong as the malfunction exists.
When the malfunction indicator isilluminated, the system may not beable to detect or signal low tirepressure as intended. TPMSmalfunctions may occur for a varietyof reasons, including the installationof replacement or alternate tires orwheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allow theTPMS to continue to functionproperly.
SeeTire Pressure MonitorOperation0408.
SeeRadio FrequencyStatement0482.
Tire Pressure Monitor
Operation
This vehicle may have a TirePressure Monitor System (TPMS).The TPMS is designed to warn thedriver when a low tire pressurecondition exists. TPMS sensors aremounted onto each tire and wheelassembly, excluding the spare tireand wheel assembly. The TPMSsensors monitor the air pressure inthe tires and transmit the tirepressure readings to a receiverlocated in the vehicle.
When a low tire pressure conditionis detected, the TPMS illuminatesthe low tire pressure warning light
