Starting the Engine
If the vehicle has a diesel engine,see the Duramax dieselsupplement.
To p l a c e t h e t r a n s m i s s i o n i n t h eproper gear:
Move the shift lever to P (Park) orN(Neutral). The engine will not startin any other position. To restart theengine when the vehicle is alreadymoving, use N (Neutral) only.
Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
SeeAdd-On Electrical
Equipment0212.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
while starting the vehicle, damage
may occur to the hydraulic power
steering system and there may be
loss of power steering assist.
Starting Procedure
1. With your foot off theaccelerator pedal, turn theignition key to START. Whenthe engine starts, let go of thekey. The idle speed will godown as your engine getswarm. Do not race the engineimmediately after starting it.

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.

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.
