Buick LaCrosse Owner Manual - 2012

9-20 Driving and Operating

Starting the Engine

Move the shift lever to P (Park) or

N (Neutral). The engine will not start

in any other position. To restart the

engine when the vehicle is already

moving, use N (Neutral) only.

Notice: 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.

Notice: The engine is designed to

work with the electronics in the

vehicle. If you add electrical parts

or accessories, you could change

the way the engine operates.

Before adding electrical

equipment, check with your

dealer. If you do not, the engine

might not perform properly. Any

resulting damage would not be

covered by the vehicle warranty.

Starting Procedure (Key Access)

1. With your foot off the accelerator

pedal, turn the ignition key to

START. When the engine starts,

let go of the ignition.

The idle speed will go down as

your engine gets warm. Do not

race the engine immediately

after starting it. Operate the

engine and transmission gently

to allow the oil to warm up and

lubricate all moving parts.

The vehicle has a

Computer-Controlled Cranking

System. This feature assists in

starting the engine and protects

components. If the ignition key is

turned to the START position,

and then released when the

engine begins cranking, the

engine will continue cranking for

a few seconds or until the

vehicle starts. If the engine does

not start and the key is held in

START for many seconds,

cranking will be stopped after

15 seconds to prevent cranking

motor damage. To prevent gear

damage, this system also

prevents cranking if the engine

is already running. Engine

cranking can be stopped by

turning the ignition switch to

ACC/ACCESSORY or

LOCK/OFF.

Notice: Cranking the engine for

long periods of time, by returning

the key 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 start after

five to 10 seconds, especially in

very cold weather (below −18°C

or 0°F), it could be flooded with

too much gasoline. Try pushing

the accelerator pedal all the way

to the floor and holding it there

as you hold the key in START,

or press the START button, for

up to a maximum of 15 seconds.
