Engine Oil Pressure
Gauge
Metric
English
The oil pressure gauge shows theengine oil pressure in psi (poundsper square inch) or kPa (kilopascals)when the engine is running.
Oil pressure may vary with enginespeed, outside temperature and oilviscosity, but readings above thelow pressure zone indicate thenormal operating range.
Areadinginthelowpressurezonemay be caused by a dangerouslylow oil level or other problemcausing low oil pressure.

178 Driving and Operating
Operate the engine andtransmission gently to allow theoil to warm up and lubricate allmoving parts.
When the Low Fuel warninglamp is on and the FUELLEVEL LOW message isdisplayed in the DriverInformation Center (DIC), theComputer-Controlled CrankingSystem is disabled to preventpossible vehicle componentdamage. When this happens,hold the ignition switch in theSTART position to continueengine 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 startafter 5-10 seconds, especiallyin very cold weather (below✓18 °C or 0 °F), it could beflooded with too muchgasoline. Try pushing theaccelerator pedal all the way tothe floor and holding it there asyou hold the key in START forup to 15 seconds. Wait at least15 seconds between each try,to allow the cranking motor tocool down. When the enginestarts, let go of the key andaccelerator. If the vehicle startsbriefly but then stops again, dothe same thing. This clears theextra gasoline from the engine.Do not race the engineimmediately after starting it.Operate the engine andtransmission gently until the oilwarms up and lubricates allmoving parts.
Fast Idle System
If equipped, this feature is availableonly with cruise control. The manualfast idle switch is operated using thecruise control buttons on the leftside of the steering wheel.
This system can be used toincrease engine idle speedwhenever the following conditionsare met:
.The parking brake is set.
.The brake pedal is not pressed.
.The vehicle must not be movingand the accelerator must not bepressed.

204 Driving and Operating
Passing
More passing distance is neededwhen towing a trailer. Thecombination will not accelerate asquickly and is longer so it isnecessary to go much fartherbeyond the passed vehicle beforereturning to the lane.
Backing Up
Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move that hand tothe left. To move the trailer to theright, move your hand to the right.Always back up slowly and,if possible, have someoneguide you.
Making Turns
Caution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, makewider turns than normal. Do this sothe trailer will not strike softshoulders, curbs, road signs, trees,or other objects. Avoid jerky orsudden maneuvers. Signal well inadvance.
If the trailer turn signal bulbs burnout, the arrows on the instrumentcluster will still flash for turns. It isimportant to check occasionally tobe sure the trailer bulbs are stillworking.
Driving on Grades
Reduce speed and shift to a lowergearbeforestarting down a long orsteep downgrade. If thetransmission is not shifted down, thebrakes might get hot and no longerwork well.
Vehicles can tow in D (Drive). Shiftthe transmission to a lower gear ifthe transmission shifts too oftenunder heavy loads and/or hillyconditions.
The Tow/Haul Mode may be used ifthe transmission shifts too often.SeeTo w / H a u l M o d e0187.
When towing at high altitude onsteep uphill grades, consider thefollowing: Engine coolant will boil atalowertemperaturethanatnormalaltitudes. If the engine is turned offimmediately after towing at highaltitude on steep uphill grades, thevehicle may show signs similar toengine overheating. To avoid this,let the engine run while parked,preferably on level ground, with thetransmission in P (Park) for a fewminutes before turning the engineoff. If the overheat warning comeson, seeEngine Overheating0230.
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.

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 System0221.
.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 Overview0218for 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

checking a cold engine prior tostarting. Remove the dipstickand check the level.
.If unable to wait two hours, theengine must be off for at least15 minutes if the engine iswarm, or at least 30 minutes ifthe engine is not warm. Pull outthe dipstick, wipe it with a cleanpaper towel or cloth, then push itback in all the way. Remove itagain, keeping the tip down, andcheck the level.
When to Add Engine Oil
If the oil is below the cross-hatchedarea at the tip of the dipstick andthe engine has been off for at least15 minutes, add 1 L (1 qt) of therecommended oil and then recheckthe level. See“Selecting the RightEngine Oil”later in this section foran explanation of what kind of oil to
use. For engine oil crankcasecapacity, seeCapacities andSpecifications0309.
Caution
Do not add too much oil. Oil
levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
have an oil level above the
operating range, i.e., the engine
has so much oil that the oil level
gets above the cross-hatched
area that shows the proper
operating range, the engine could
be damaged. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
SeeEngine Compartment Overview0218for the location of the engineoil fill cap.
Add enough oil to put the levelsomewhere in the proper operatingrange. Push the dipstick all the wayback in when through.
Selecting the Right Engine Oil
Selecting the right engine oildepends on both the proper oilspecification and viscosity grade.SeeRecommended Fluids andLubricants0305.
Specification
Ask for and use engine oils thatmeet the dexos1™specification.Engine oils that have beenapproved by GM as meeting thedexos1 specification are markedwith the dexos1 approved logo. Seewww.gmdexos.com.
