216 Driving and Operating
{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
Electric Power Steering
The vehicle has electric powersteering. It does not have powersteering fluid. Regular maintenanceis not required.
If power steering assist is lost dueto a system malfunction, the vehiclecan be steered, but may requireincreased effort.
See your dealer if there is aproblem.
If the steering wheel is turned until itreaches the end of its travel and isheld against that position for anextended period of time, powersteering assist may be reduced.
If the steering assist is used for anextended period of time, powerassist may be reduced.
Normal use of the power steeringassist should return when thesystem cools down.
See specific vehicle steeringmessages underSteering SystemMessages0137.Seeyourdealerifthere is a problem.

Chevrolet Colorado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-10122675) - 2017 - crc - 8/22/16
218 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.
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)0258.
.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.

Driving and Operating 223
{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. SeeTires0316.
.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.

272 Driving and Operating
minutes before turning the engineoff. If the overheat warning comeson, seeEngine Overheating0296.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but donot shift into P (Park) yet. Turnthe wheels into the curb iffacing downhill or into traffic iffacing uphill.
2. Have someone place chocksunder the trailer wheels.
3. When the wheel chocks are inplace, release the regularbrakes until the chocks absorbthe load.
4. Reapply the brake pedal. Thenapply the parking brake andshift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brakepedal.
2. Start the engine.
3. Shift into a gear.
4. Release the parking brake.
5. Let up on the brake pedal.
6. Drive slowly until the trailer isclear of the chocks.
7. Stop and have someone pickup and store the chocks.
Maintenance when Trailer
Towing
The vehicle needs service moreoften when pulling a trailer. SeeMaintenance Schedule0366.Things that are especially importantin trailer operation are automatictransmission fluid, engine oil, axlelubricant, belts, cooling system, and
brake system. It is a good idea toinspect these before and duringthe trip.
Check periodically to see that allhitch nuts and bolts are tight.
Trailer Towing
Do not tow a trailer during break-in.SeeNew Vehicle Break-In0232.
{Warning
The driver can lose control when
pulling a trailer if the correct
equipment is not used or the
vehicle is not driven properly. For
example, if the trailer is too heavy
or the trailer brakes are
inadequate for the load, the
vehicle may not stop as expected.
The driver and passengers could
be seriously injured. The vehicle
may also be damaged; the
resulting repairs would not be
covered by the vehicle warranty.
Pull a trailer only if all the steps in
this section have been followed.

Engine Oil
For diesel engine vehicles, see“Engine Oil”in the Duramax dieselsupplement.
To e n s u r e p r o p e r e n g i n eperformance and long life, carefulattention must be paid to engine oil.Following these simple, butimportant steps will help protectyour investment:
.Use engine oil approved to theproper specification and of theproper viscosity grade. See“Selecting the Right Engine Oil”in this section.
.Check the engine oil levelregularly and maintain theproper oil level. See“CheckingEngine Oil”and“When to AddEngine Oil”in this section.
.Change the engine oil at theappropriate time. SeeEngine OilLife System0288.
.Always dispose of engine oilproperly. See“What to Do withUsed Oil”in this section.
Checking Engine Oil
Check the engine oil level regularly,every 650 km (400 mi), especiallyprior to a long trip. The engine oildipstick handle is a loop. SeeEngine Compartment Overview0283for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center(DIC) message displays, check theoil level.
Follow these guidelines:
.To g e t a n a c c u r a t e r e a d i n g , p a r kthe vehicle on level ground.Check the engine oil level afterthe engine has been off for atleast two hours. Checking theengine oil level on steep gradesor too soon after engine shutoffcan result in incorrect readings.Accuracy improves when
