2007 CHEVROLET COLORADO stop start

Surface Obstacles:Unseen or hidden obstacles
can be hazardous. A rock, log, hole, rut, or
bump can startle you if you are not prepared
for them. Often these obstacles are hidden
by grass, bushes, snow, or even the rise and
fall of the terrain itself. Here are some things
to consider:
Is the path ahead clear?
Will the surface texture change abruptly
up ahead?
Does the travel take you uphill or
downhill? There is more discussion of
these subjects later.
Will you have to stop suddenly or change
direction quickly?
When you drive over obstacles or rough
terrain, keep a rm grip on the steering wheel.
Ruts, troughs, or other surface features can
jerk the wheel out of your hands if you are
not prepared.When you drive over bumps, rocks, or other
obstacles, the wheels can leave the ground.
If this happens, even with one or two wheels,
you cannot control the vehicle as well or at all.
Because you will be on an unpaved surface,
it is especially important to avoid sudden
acceleration, sudden turns, or sudden braking.
In a way, off-road driving requires a different
kind of alertness from driving on paved roads
and highways. There are no road signs, posted
speed limits, or signal lights. You have to use
your own good judgment about what is safe and
what is not.
Drinking and driving can be very dangerous on any
road. And this is certainly true for off-road driving.
At the very time you need special alertness and
driving skills, your reexes, perceptions, and
judgment can be affected by even a small amount
of alcohol. You could have a serious — or even
fatal — accident if you drink and drive or ride with
a driver who has been drinking. SeeDrunken
Driving on page 247.

Sound the horn as you approach the top
of the hill to let opposing traffic know you
are there.
Use your headlamps even during the day.
They make your vehicle more visible to
oncoming traffic.
{CAUTION:
Driving to the top (crest) of a hill at full
speed can cause an accident. There could
be a drop-off, embankment, cliff, or even
another vehicle. You could be seriously
injured or killed. As you near the top
of a hill, slow down and stay alert.
Q:What should I do if my vehicle stalls,
or is about to stall, and I cannot make
it up the hill?
A:If this happens, there are some things you
should do, and there are some things you
must not do. First, here is what youshoulddo:
Push the brake pedal to stop the vehicle
and keep it from rolling backwards. Also,
apply the parking brake.
If your engine is still running, shift the
transmission to REVERSE (R), release the
parking brake, and slowly back down the
hill in REVERSE (R).
If your engine has stopped running, you will
need to restart it. With the brake pedal
pressed and the parking brake still applied,
shift the transmission to PARK (P), or shift
to NEUTRAL if your vehicle has a manual
transmission, and restart the engine. Then,
shift to REVERSE (R), release the parking
brake, and slowly back down the hill as
straight as possible in REVERSE (R).
268

Q:Are there some things I should not do
when driving down a hill?
A:Yes! These are important because if you
ignore them you could lose control and
have a serious accident.
When driving downhill, avoid turns that take
you across the incline of the hill. A hill that
is not too steep to drive down may be
too steep to drive across. You could roll
over if you do not drive straight down.
Never go downhill with the transmission in
NEUTRAL (N), or with the clutch pedal
pressed down with a manual transmission.
This is called “free-wheeling.” The brakes will
have to do all the work and could overheat
and fade.
Q:Am I likely to stall when going downhill?
A:It is much more likely to happen going
uphill. But if it happens going downhill,
here is what to do.
1. Stop your vehicle by applying the regular
brakes. Apply the parking brake.
2. Shift to PARK (P), or to NEUTRAL with the
manual transmission, and, while still braking,
restart the engine.
3. Shift back to a low gear, release the parking
brake, and drive straight down.
4. If the engine will not start, get out and
get help.
271

Q:What if I am driving across an incline
that is not too steep, but I hit some
loose gravel and start to slide downhill.
What should I do?
A:If you feel your vehicle starting to slide
sideways, turn downhill. This should help
straighten out the vehicle and prevent
the side slipping. However, a much better
way to prevent this is to get out and
“walk the course” so you know what the
surface is like before you drive it.
Stalling on an Incline
{CAUTION:
Getting out on the downhill (low) side
of a vehicle stopped across an incline is
dangerous. If the vehicle rolls over, you
could be crushed or killed. Always get
out on the uphill (high) side of the vehicle
and stay well clear of the rollover path.If your vehicle stalls when you are crossing
an incline, be sure you, and any passengers,
get out on the uphill side, even if the door there
is harder to open. If you get out on the downhill
side and the vehicle starts to roll over, you will
be right in its path.
If you have to walk down the slope, stay out of
the path the vehicle will take if it does roll over.
273

Driving in Water
{CAUTION:
Driving through rushing water can be
dangerous. Deep water can sweep your
vehicle downstream and you and your
passengers could drown. If it is only
shallow water, it can still wash away the
ground from under your tires, and you
could lose traction and roll the vehicle
over. Do not drive through rushing water.
Heavy rain can mean ash ooding, and ood
waters demand extreme caution.Find out how deep the water is before you
drive through it. If it is deep enough to cover
the wheel hubs, axles, or exhaust pipe, do not
try it — you probably will not get through.
Also, water that deep can damage the axle
and other vehicle parts.
If the water is not too deep, drive slowly through it.
At faster speeds, water splashes on the ignition
system and your vehicle can stall. Stalling can
also occur if you get the tailpipe under water.
And, as long as the tailpipe is under water, you
will never be able to start the engine. When you
go through water, remember that when the brakes
get wet, it may take you longer to stop.
SeeDriving in Rain and on Wet Roads on page 278
for more information on driving through water.
275

Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble.
On a wet road, you cannot stop, accelerate,
or turn as well because your tire-to-road
traction is not as good as on dry roads.And, if your tires do not have much tread left,
you will get even less traction. It is always wise to
go slower and be cautious if rain starts to fall
while you are driving. The surface may get wet
suddenly when your reexes are tuned for driving
on dry pavement.
The heavier the rain, the harder it is to see.
Even if your windshield wiper blades are in good
shape, a heavy rain can make it harder to see
road signs and traffic signals, pavement markings,
the edge of the road, and even people walking.
It is wise to keep your wiping equipment in
good shape and keep your windshield washer
uid reservoir lled with washer uid. Replace your
windshield wiper inserts when they show signs
of streaking or missing areas on the windshield,
or when strips of rubber start to separate from
the inserts.

Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to
the proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop
and back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted.
Reduce your speed according to your
speedometer, not to your sense of motion.
After driving for any distance at higher speeds,
you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such
as after a day’s work — do not plan to make
too many miles that rst part of the journey.
Wear comfortable clothing and shoes you can
easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course,
you will nd experienced and able service experts
in GM dealrships all across North America. They
will be ready and willing to help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the
lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you delay
your trip a short time to avoid a major storm
system?
Maps:Do you have up-to-date maps?
283

Making Turns
Notice:Making very sharp turns while
trailering could cause the trailer to come in
contact with the vehicle. Your vehicle could
be damaged. Avoid making very sharp
turns while trailering.
When you’re turning with a trailer, make wider turns
than normal. Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have
extra wiring and a heavy-duty turn signal asher.
The arrows on your instrument panel will ash
whenever you signal a turn or lane change.
Properly hooked up, the trailer lamps will also
ash, telling other drivers you’re about to
turn, change lanes or stop.
When towing a trailer, the arrows on your
instrument panel will ash for turns even if
the bulbs on the trailer are burned out.Thus, you may think drivers behind you are seeing
your signal when they are not. It’s important to
check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear before
you start down a long or steep downgrade.
If you don’t shift down, you might have to use
your brakes so much that they would get hot
and no longer work well.
When towing at high altitude on steep uphill
grades, consider the following: Engine coolant
will boil at a lower temperature than at normal
altitudes. If you turn your engine off immediately
after towing at high altitude on steep uphill grades,
your vehicle may show signs similar to engine
overheating. To avoid this, let the engine run
while parked (preferably on level ground) with
the automatic transmission in PARK (P) (or
the manual transmission out of gear and the
parking brake applied) for a few minutes before
turning the engine off. If you do get the overheat
warning, seeEngine Overheating on page 348.
