warning CHEVROLET UPLANDER 2008 1.G Service Manual

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 that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates if it senses that
one or both of the front wheels are spinning or beginning
to lose traction. When this happens, the system
brakes the spinning wheel(s) and/or reduces engine
power to limit wheel spin.
The TRACTION CONTROL ACTIVE message will come
on in the Driver Information Center (DIC) when the
traction control system is limiting wheel spin. You may
feel or hear the system working, but this is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control.This warning light will
come on to let you know if
there is a problem with
your traction control
system.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
If the SERVICE TRACTION SYSTEM message in the
DIC comes on and stays on or comes on while you are
driving, there’s a problem with your traction control
system. Have the traction control system serviced by your
dealer/retailer as soon as possible.
When this warning message is on, the TRACTION
CONTROL OFF message in the DIC will come on to
remind you that the system will not limit wheel spin.
Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should always
leave the system on. But you can turn the traction control
system off if you ever need to. You should turn the
system off if your vehicle ever gets stuck in sand, mud or
snow and rocking the vehicle is required. SeeRocking
Your Vehicle to Get It Out on page 4-21andIf Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 4-20.
4-6

To turn the system off,
press the traction control
button located on the
center of the instrument
panel.
If the system is limiting wheel spin when you press the
button, the TRACTION CONTROL ACTIVE message will
go off, but the system will not turn off until there is no
longer a current need to limit wheel spin. The TRACTION
CONTROL OFF message will come on to remind you the
system is off. You can turn the system back on at any
time by pressing the button again. The traction control
system warning message should go off.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.StabiliTrak®System
Your vehicle may be equipped with StabiliTrak®which
combines anti-lock brake, traction and stability control
systems and helps the driver maintain directional control
of the vehicle in most driving conditions.
When you rst start your vehicle and begin to drive
away, the system performs several diagnostic checks to
insure there are no problems. You may hear or feel
the system working. This is normal and does not mean
there is a problem with your vehicle.
If the system fails to turn on or activate, the SERVICE
STABILITY SYSTEM message will be displayed on
the Driver Information Center (DIC). If the vehicle has
gone through heavy acceleration or braking or multiple
turns during the rst two miles of driving after starting
your vehicle, the STABILITY CONTROL OFF message
may appear on the DIC. If this is the case, your
vehicle does not need servicing. You will need to turn
the vehicle off and then restart it to initialize StabiliTrak
®.
If either message appears on the DIC, and your
vehicle has not gone through hard acceleration, braking
or multiple turns in the rst two miles of driving, your
vehicle should be taken in for service.
4-7

The STABILITY CONTROL ACTIVE message will
appear on the DIC only when the system is both on and
activated. It means that an advanced
computer-controlled system has come on to help your
vehicle continue to go in the direction in which you
are steering. StabiliTrak
®activates when the computer
senses that your vehicle is just starting to spin, as it
might if you hit a patch of ice or other slippery spot on
the road. When the system activates, you may hear
a noise or feel a vibration in the brake pedal. This
is normal. When the STABILITY CONTROL ACTIVE
message is on, you should continue to steer in the
direction you want to go. The system is designed to help
you in bad weather or other difficult driving situations
by making the most of whatever road conditions
will permit. For more information on the stability
messages, seeDriver Information Center (DIC) on
page 3-50.
If the StabiliTrak
®system turns off, the traction control
system warning light will illuminate, and the STABILITY
CONTROL OFF message will appear on the DIC to
warn the driver that StabiliTrak
®is no longer available
to assist you with directional control of the vehicle.
Adjust your driving accordingly.
To realize the full benets of the stability enhancement
system, you should normally leave StabiliTrak
®on,
but it may be necessary to turn the system off if yourvehicle is stuck in sand, mud, ice or snow, and you
want to “rock” your vehicle to attempt to free it.
SeeRocking Your Vehicle to Get It Out on page 4-21
andIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-20.
Traction Control Operation
The traction control system is part of the StabiliTrak®
system. Traction control limits wheel spin by reducing
engine power to the wheels (engine speed
management) and by applying brakes.
The traction control system is enabled automatically
when you start your vehicle. It will activate and display
the TRACTION CONTROL ACTIVE message in the
DIC if it senses that one or both of the front wheels are
spinning or beginning to lose traction while driving.
If the brake traction-control system activates constantly
or if the brakes have heated up due to high-speed
braking, brake traction-control will be disabled and the
TRACTION CONTROL ACTIVE message will be
displayed. In the limited mode, the traction control
system will only use engine traction-control and is limited
in its ability to provide optimal performance since the
system will not utilize brake traction-control to control
slip on the drive wheels. The system will return to normal
operation after the brakes have cooled. This can take
up to two minutes or longer depending on brake usage.
4-8

Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you
will want to slow down and adjust your driving to
these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try your
best to avoid sudden steering, acceleration, or braking,
including reducing vehicle speed by shifting to a lower
gear. Any sudden changes could cause the tires to
slide. You may not realize the surface is slippery until
your vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow on
the road to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Antilock Brake System (ABS) helps
avoid only the braking skid.
Driving at Night
Night driving is more dangerous than day driving
because some drivers are likely to be impaired — by
alcohol or drugs, with night vision problems, or by
fatigue.
Night driving tips include:
Drive defensively.
Do not drink and drive.
Reduce headlamp glare by adjusting the inside
rearview mirror.
Slow down and keep more space between you and
other vehicles because your headlamps can only
light up so much road ahead.
Watch for animals.
When tired, pull off the road.
Do not wear sunglasses.
Avoid staring directly into approaching headlamps.
Keep the windshield and all glass on your vehicle
clean — inside and out.
Keep your eyes moving, especially during turns or
curves.
No one can see as well at night as in the daytime. But,
as we get older, these differences increase. A
50-year-old driver might need at least twice as much
light to see the same thing at night as a 20-year-old.
4-13

Driving in Rain and on Wet Roads
Rain and wet roads can reduce vehicle traction
and affect your ability to stop and accelerate. Always
drive slower in these types of driving conditions
and avoid driving through large puddles and
deep-standing or owing water.
{CAUTION:
Wet brakes can cause accidents. They might
not work as well in a quick stop and could
cause pulling to one side. You could lose
control of the vehicle.
After driving through a large puddle of water
or a car/vehicle wash, lightly apply the brake
pedal until the brakes work normally.
Flowing or rushing water creates strong
forces. Driving through owing water could
cause your vehicle to be carried away. If this
happens, you and other vehicle occupants
could drown. Do not ignore police warnings
and be very cautious about trying to drive
through owing water.
Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle’s tires so they actually ride on the
water. This can happen if the road is wet enough and
you are going fast enough. When your vehicle is
hydroplaning, it has little or no contact with the road.
There is no hard and fast rule about hydroplaning. The
best advice is to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather driving tips
include:
Allow extra following distance.
Pass with caution.
Keep windshield wiping equipment in good shape.
Keep the windshield washer uid reservoir lled.
Have good tires with proper tread depth. SeeTires
on page 5-48.
4-14

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You might want to put winter emergency supplies in
your vehicle.
Include an ice scraper, a small brush or broom, a
supply of windshield washer uid, a rag, some winter
outer clothing, a small shovel, a ashlight, a red
cloth, and a couple of reective warning triangles. And,
if you will be driving under severe conditions, include
a small bag of sand, a piece of old carpet, or a couple of
burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Also seeTires on page 5-48.
Driving on Snow or Ice
Most of the time, those places where the tires meet the
road probably have good traction.
However, if there is snow or ice between the tires and
the road, you can have a very slippery situation.
You have a lot less traction, or grip, and need to be
very careful.What is the worst time for this? Wet ice. Very cold snow
or ice can be slick and hard to drive on. But wet ice
can be even more trouble because it can offer the least
traction of all. You can get wet ice when it is about
freezing, 32°F (0°C), and freezing rain begins to fall. Try
to avoid driving on wet ice until salt and sand crews
can get there.
Whatever the condition — smooth ice, packed, blowing,
or loose snow — drive with caution.
4-17

If your vehicle has a traction system, it will improve your
ability to accelerate when driving on a slippery road. But
you can turn the traction system off if you ever need to.
You should turn the traction system off if your vehicle
ever gets stuck in sand, mud, ice, or snow. SeeIf Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 4-20. Even if your vehicle has a traction system,
slow down and adjust your driving to the road conditions.
Under certain conditions, you might want to turn the
traction system off, such as when driving through deep
snow and loose gravel, to help maintain vehicle motion at
lower speeds. SeeTraction Control System (TCS) on
page 4-6andStabiliTrak
®System on page 4-7.
If your vehicle does not have a traction system,
accelerate gently. Try not to break the fragile traction. If
you accelerate too fast, the drive wheels will spin
and polish the surface under the tires even more.
The Antilock Brake System (ABS) improves your
vehicle’s stability when you make a hard stop on a
slippery road. Even though you have ABS, begin
stopping sooner than you would on dry pavement. See
Antilock Brake System (ABS) on page 4-5.
Allow greater following distance on any
slippery road.
Watch for slippery spots. The road might be ne until
you hit a spot that is covered with ice. On an
otherwise clear road, ice patches can appear in
shaded areas where the sun cannot reach, such asaround clumps of trees, behind buildings, or under
bridges. Sometimes the surface of a curve or an
overpass can remain icy when the surrounding roads
are clear. If you see a patch of ice ahead of you,
brake before you are on it. Try not to brake while you
are actually on the ice, and avoid sudden steering
maneuvers.
If You Are Caught in a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay with
your vehicle unless you know for sure that you are near
help and you can hike through the snow. Here are
some things to do to summon help and keep yourself
and your passengers safe:
Turn on the hazard warning ashers.
Tie a red cloth to your vehicle to alert police that
you have been stopped by the snow.
Put on extra clothing or wrap a blanket around you.
If you do not have blankets or extra clothing, make
body insulators from newspapers, burlap bags,
rags, oor mats — anything you can wrap around
yourself or tuck under your clothing to keep warm.

{CAUTION:
Fuel can spray out on you if you open the fuel
cap too quickly. If you spill fuel and then
something ignites it, you could be badly burned.
This spray can happen if your tank is nearly full,
and is more likely in hot weather. Open the fuel
cap slowly and wait for any hiss noise to stop.
Then unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or overll the
tank and wait a few seconds after you have nished
pumping before removing the nozzle. Clean fuel
from painted surfaces as soon as possible.
SeeWashing Your Vehicle on page 5-93.
When replacing the fuel cap, turn it clockwise until it
clicks. Make sure the cap is fully installed. The diagnostic
system can determine if the fuel cap has been left off or
improperly installed. This would allow fuel to evaporate
into the atmosphere. SeeMalfunction Indicator Lamp on
page 3-44.The CHECK GAS CAP message will be displayed in the
Driver Information Center (DIC) if the fuel cap is not
properly installed. SeeDIC Warnings and Messages on
page 3-58for more information.
{CAUTION:
If a re starts while you are refueling, do not
remove the nozzle. Shut off the ow of fuel by
shutting off the pump or by notifying the
station attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer/retailer can get one
for you. If you get the wrong type, it may not t
properly. This may cause your malfunction indicator
lamp to light and may damage your fuel tank and
emissions system. SeeMalfunction Indicator Lamp
on page 3-44.
