2007 CHEVROLET KODIAK power steering

Ignition Positions
With your key in the ignition switch, you can turn it
to five different positions.
A (ACCESSORY):This position allows you to use
things like the radio, power windows and the
windshield wipers when the engine is off. To get
into ACCESSORY, push in the key and turn it
toward you. Your steering wheel will remain
locked, just as it was before you inserted the key.B (LOCK):This position locks your ignition,
steering wheel and transmission. It is a
theft-deterrent feature. You will only be able to
remove your key when the ignition is turned
to LOCK.
C (OFF):This position lets you turn off the engine
but still turn the steering wheel. It does not lock
the steering wheel like LOCK. Use OFF if
you must have your vehicle in motion while the
engine is off.
D (RUN):This is the position for driving.
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.
E (START):This position starts your engine.

{CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in the right front
passenger’s seat) until you have your
vehicle serviced. SeeAirbag Off Switch on
page 76andAirbag Readiness Light on
page 165for more on this, including
important safety information.
Charging System Light
The charging system
light may be located in
the instrument panel
cluster, or with the
auxiliary warning lights
in the center of the
instrument panel.
It should come on briefly when you turn on the
ignition, before the engine is running, as a check to
show that it is working.
If it stays on, or comes on while you are driving,
have your vehicle checked right away. You
could have a loose generator drive belt or some
other problem.
Driving while this light is on will drain your battery.
If you must drive a short distance with the light
on, turn off your radio and other accessories.
Sustained driving with a generator failure could
result in a lack of back-up braking if the engine
quits or the power steering pump should fail.

Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic.
This is a mistake. The brakes may not have time to
cool between hard stops. The brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic
following distances, you will eliminate a lot of
unnecessary braking. That means better braking
and longer brake life.
If your vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the engine stops, you will still have
some power brake assist. But you will use it
when you brake. Once the power assist is used
up, it may take longer to stop and the brake pedal
will be harder to push.Hydraulic Brake Systems
If your engine stops running, or if your primary
brake system stops working, your vehicle has a
reserve power assist system to help you slow down.
Just slowly and steadily apply the brake pedal until
you can safely get off the road. The pedal will seem
harder to push down. Do not pump the pedal; the
system will not work well or at all that way.
You may find that the steering wheel seems hard
to turn when you are turning and braking at
the same time. Also, the primary brake warning
light may come on and the warning tone may
sound. This is normal because the main hydraulic
brake system and power steering both use the
power steering pump. If this ever happens, let up
on the brake pedal a little. When you let up on
the brake pedal in that situation, it lets the steering
get a little more help from the pump.
211

To turn the system on
or off, press the traction
control button located
on the instrument panel.
If you used the TCS button to turn the system off,
the light in the top of the button will come on and
stay on. You can turn the TCS back on at any time
by pressing the button again; the light should go off.Steering
Power Steering
If you lose power steering assist because the
engine stops or the system is not functioning,
you can steer but it will take much more effort.
On vehicles with hydraulic brakes, the power
steering and main hydraulic brake system both use
the power steering pump. SeeBraking on page 210.
Steering Tips
Driving on Curves
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned
on the news happen on curves. Here is why:
Experienced driver or beginner, each of us is
subject to the same laws of physics when driving on
curves. The traction of the tires against the road
surface makes it possible for the vehicle to change
its path when you turn the front wheels. If there is
no traction, inertia will keep the vehicle going in the
same direction. If you have ever tried to steer a
vehicle on wet ice, you will understand this.

Power Steering Fluid
SeeScheduled Maintenance on page 363to
determine when to check your power steering fluid.
How To Check Power Steering Fluid
Check your power steering fluid only when the
engine is warm. If the engine is not warm, you
probably will not get an accurate reading.
If the fluid level is between the MIN (Minimum) and
MAX (Maximum) marks, you have enough. If you
need fluid, add only enough of the proper fluid to
bring it in between the MIN and MAX marks.
If your power steering fluid level is low, this can
cause the brake or service brakes soon warning
lights to come on. In addition, the steering
effort and emergency brake distance could
increase.If either light remains on after you have added
power steering fluid to the proper level, then shut
off the engine for 10 seconds. This should
reset the brake warning lights. If one or both lights
stay on, see “Hydraulic Brake System Warning
Lights” underBrake System Warning Light
on page 169for more information.
What to Use
To determine what kind of fluid to use, see
Part C: Recommended Fluids and Lubricants on
page 397.
Notice:When adding power steering uid or
making a complete uid change, always
use the proper uid. Failure to use the proper
uid can cause leaks and damage hoses
and seals.
