2007 CHEVROLET TAHOE Key switch

Ignition Positions
Use the key to turn the ignition switch to four
different positions.
A (LOCK):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will
only be able to remove the key when the ignition is
turned to LOCK.Notice:Using a tool to force the key from the
ignition switch could cause damage or break
the key. Use the correct key and turn the key
only with your hand. Make sure the key is all the
way in. If it is, turn the steering wheel left and
right while you turn the key hard. If none of this
works, then your vehicle needs service.
B (ACCESSORY):This position lets you use
things like the radio and the windshield wipers when
the engine is off.
Lengthy operation of features such as the radio in
the ACCESSORY ignition position and the RUN
position may drain the battery and prevent your
vehicle from starting. Do not operate your vehicle in
the ACCESSORY ignition position for a long period
of time.
C (RUN):This is the position for driving. It is the
position the switch returns to after the engine starts,
and you release the key.
The battery could be drained if you leave the key in
the ACCESSORY or RUN position with the engine
off. You may not be able to start your vehicle if the
battery is allowed to drain for an extended period
of time.
D (START):This position starts the engine.

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 the ACCESSORY or LOCK
position.
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 allow
the cranking motor to cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or
−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator pedal all
the way to the oor and holding it there as
you hold the key in START for up to a
maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If
the vehicle starts briey but then stops again,
do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transmission gently until the oil
warms up and lubricates all moving parts.
Notice:Your engine is designed to work with
the electronics in your 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, your engine might not
perform properly. Any resulting damage would
not be covered by your vehicle’s warranty.
