power steering CHEVROLET COLORADO 2007 1.G Owners Manual

Ignition Positions
With the key in
the ignition switch,
you can turn to
four different
positions.
LOCK (A):This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. It will locks the steering wheel on manual
transmission vehicles when the key is removed.
It is a theft-deterrent feature. You will only be
able to remove your key when the ignition is
turned to LOCK.If you have an automatic transmission, the ignition
switch cannot be turned to LOCK unless the
shift lever is in PARK (P).
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.
ACC (ACCESSORY) (B):This is the position in
which you can operate your electrical accessories
or items plugged into the accessory power
outlets. On automatic transmission vehicles,
this position unlocks the ignition. On manual
transmission vehicles, it unlocks the ignition and
steering wheel. Use this position if your vehicle
must be pushed or towed.
119

Automatic Transmission Operation
Your automatic transmission has a shift lever on
the steering column.
It features an electronic shift position indicator
within the instrument cluster. This display must
be powered anytime the shift lever is capable
of being moved out of PARK (P). This means that
if your key is turned off, but not in LOCK, there
will be a small current drain on your battery which
could discharge your battery over a period of
time. If you need to leave your key in the ignition
but not in LOCK for an extended period, it is
recommended that you disconnect the battery
cable from the battery to prevent discharging
your battery.
There are several different positions for your
shift lever.PARK (P):This position locks your rear wheels.
It is the best position to use when you start
your engine because your vehicle cannot
move easily.
{CAUTION:
It is dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P)
with the parking brake rmly set. Your
vehicle can roll.
Do not leave your vehicle when the
engine is running unless you have to.
If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle
will not move, even when you are on
fairly level ground, always set your
parking brake and move the shift lever
to PARK (P). SeeShifting Into Park (P)
(Automatic Transmission) on page 135.
If you are pulling a trailer, seeTowing
a Trailer on page 306.

Four-Wheel Drive
If your vehicle has four-wheel drive, you can send
your engine’s driving power to all four wheels for
extra traction. To get the best performance out of
four-wheel drive, you must be familiar with its
operation. Read the part that follows before using
four-wheel drive. You should use two-wheel-drive
high for most normal driving conditions.
Notice:Driving on clean, dry pavement in
four-wheel drive for an extended period of
time can cause premature wear on your
vehicle’s powertrain. Do not drive on clean,
dry pavement in Four-Wheel Drive for
extended periods of time.
Notice:If your vehicle has four-wheel drive
and the compact spare tire is installed on
your vehicle, do not drive in four-wheel drive
until you can have your at tire repaired and/or
replaced. You could damage your vehicle,
and the repair costs would not be covered
by your warranty. Never use four-wheel drive
when the compact spare tire is installed
on your vehicle.The transfer case buttons are located to the right
of the steering wheel on the instrument panel.

Remember: ABS does not change the time
you need to get your foot up to the brake pedal
or always decrease stopping distance. If you
get too close to the vehicle in front of you,
you will not have time to apply the brakes if that
vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though
you have ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down rmly and let anti-lock work for you.
You might feel the brakes vibrate or notice
some noise, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same
time. In many emergencies, steering can help
you more than even the very best braking.
Traction Control System (TCS)
Your vehicle may have a Traction Control
System (TCS) that limits wheel spin. This is
especially useful in slippery road conditions.
The system operates only if it senses that
one or both of the rear wheels are spinning or
beginning to lose traction. When this happens,
the system reduces engine power and may
also upshift the transmission to limit wheel spin.
You may feel or hear the system working,
but this is normal.
The TCS button is
located on your
instrument panel.
Press this button
to turn the TCS
off and on.
When the traction control system is turned off,
an indicator light on the button will illuminate.

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.
Steering Tips
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.
The traction you can get in a curve depends on
the condition of the tires and the road surface,
the angle at which the curve is banked, and your
speed. While you are in a curve, speed is the
one factor you can control.Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have
to do their work where the tires meet the road.
Adding the sudden acceleration can demand
too much of those places. You can lose control.
What should you do if this ever happens? Ease
up on the accelerator pedal, steer the vehicle
the way you want it to go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds
are based on good weather and road conditions.
Under less favorable conditions you will want
to go slower.
If you need to reduce your speed as you approach
a curve, do it before you enter the curve, while
the front wheels are straight ahead.
Try to adjust your speed so you can “drive” through
the curve. Maintain a reasonable, steady speed.
Wait to accelerate until you are out of the curve,
and then accelerate gently into the straightaway.
Adding non-dealer/non-retailer accessories can
affect your vehicle’s performance. SeeAccessories
and Modications on page 324.

What is beyond the hill? Is there a cliff,
an embankment, a drop-off, a fence?
Get out and walk the hill if you do not know.
It is the smart way to nd out.
Is the hill simply too rough? Steep hills often
have ruts, gullies, troughs, and exposed
rocks because they are more susceptible
to the effects of erosion.
Driving Uphill
Once you decide you can safely drive up the
hill, you need to take some special steps.
Use a low gear and get a rm grip on the
steering wheel.
Get a smooth start up the hill and try to
maintain your speed. Do not use more power
than you need, because you do not want
the wheels to start spinning or sliding.
{CAUTION:
Turning or driving across steep hills can
be dangerous. You could lose traction,
slide sideways, and possibly roll over.
You could be seriously injured or killed.
When driving up hills, always try to go
straight up.
Try to drive straight up the hill if at all possible.
If the path twists and turns, you might want to
nd another route.
Ease up on your speed as you approach the
top of the hill.
Attach a ag to the vehicle to make you more
visible to approaching traffic on trails or hills.

Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 332
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you do
not do this, the oil dipstick might not show the
actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the way.
Remove it again, keeping the tip down, and
check the level.
333

Engine Fan Noise
This vehicle has a clutched engine cooling fan.
When the clutch is engaged, the fan spins faster
to provide more air to cool the engine. In most
everyday driving conditions, the clutch is not
engaged. This improves fuel economy and reduces
fan noise. Under heavy vehicle loading, trailer
towing and/or high outside temperatures, the
fan speed increases when the clutch engages.
So you may hear an increase in fan noise.
This is normal and should not be mistaken as
the transmission slipping or making extra shifts.
It is merely the cooling system functioning
properly. The fan will slow down when additional
cooling is not required and the clutch disengages.
You may also hear this fan noise when you
start the engine. It will go away as the fan
clutch disengages.
Power Steering Fluid
The power steering uid
reservoir is located near
the front of the engine
compartment, behind
the radiator. SeeEngine
Compartment Overview
on page 332for
reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power
steering uid unless you suspect there is a leak
in the system or you hear an unusual noise.
A uid loss in this system could indicate a problem.
Have the system inspected and repaired.
355

How to Check Power Steering Fluid
1. Turn the key off and let the engine
compartment cool down.
2. Wipe the cap and the top of the
reservoir clean.
3. Unscrew the cap and wipe the dipstick
with a clean rag.
4. Replace the cap and completely tighten it.
5. Then remove the cap again and look at
the uid level on the dipstick.
The level should be between the ADD and
FULL marks. If necessary, add only enough
uid to bring the level up to the proper range.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 452.
Always use the proper uid. Failure to use the
proper uid can cause leaks and damage hoses
and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer uid, be sure
to read the manufacturer’s instructions before
use. If you will be operating your vehicle in an area
where the temperature may fall below freezing,
use a uid that has sufficient protection against
freezing.
Adding Washer Fluid
Open the cap with the
washer symbol on it.
Add washer uid
until the tank is full. See
Engine Compartment
Overview on page 332
for reservoir location.
