2009 CHEVROLET TRAIL BLAZER clock

Attach a ag to the vehicle to be more visible to
approaching traffic on trails or hills.
Sound the horn as you approach the top of the hill
to let opposing traffic know you are there.
Use headlamps even during the day to make the
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.If the vehicle stalls, or is about to stall, and you cannot
make it up the hill:
Push the brake pedal to stop the vehicle and keep
it from rolling backwards and apply the parking
brake.
If the engine is still running, shift the transmission
to R (Reverse), release the parking brake, and
slowly back down the hill in R (Reverse).
If the engine has stopped running, you need to
restart it. With the brake pedal pressed and the
parking brake still applied, shift the transmission
to P (Park) and restart the engine. Then, shift
to R (Reverse), release the parking brake, and
slowly back down the hill as straight as possible
in R (Reverse).
While backing down the hill, put your left hand on the
steering wheel at the 12 o’clock position so you can
tell if the wheels are straight and can maneuver as
you back down. It is best to back down the hill with
the wheels straight rather than in the left or right
direction. Turning the wheel too far to the left or
right will increase the possibility of a rollover.

Electronically Controlled Air
Suspension System
With this feature, an electronically controlled air
suspension system automatically keeps the vehicle level
as it is loaded and unloaded. The system includes a
compressor, two height sensors and two air springs
supporting the rear axle.
The system also has an internal clock to prevent
overheating if the inator is used for prolonged periods.
If the system overheats, all leveling function stops
until the system cools down.
The ignition has to be on for the system to inate, in order
to raise the vehicle to the standard ride height after
loading. The system can lower the vehicle to the standard
ride height after unloading with the ignition on and also for
up to 30 minutes after the ignition has been turned off.
The compressor may be heard while it is operating when
the vehicle is being loaded, and periodically as the
system adjusts the vehicle to the standard ride height.
Load leveling will not function normally with the inator
hose attached to the inator outlet. Remove the inator
hose from the outlet during loading and unloading.
If the vehicle is parked for an extended period of time,
some bleed down of the suspension is normal. Upon
starting the vehicle, proper height will be achieved.
Overload Protection
The air suspension system is equipped with overload
protection. Overload protection is designed to protect
the air suspension system, and it is an indicator to the
driver that the vehicle is overloaded. When the overload
protection mode is on, it will not allow damage to the
air compressor. However, do not overload the vehicle.
SeeLoading the Vehicle on page 4-33.
If the suspension remains at a low height, the rear axle
load has exceeded GAWR (Gross Axle Weight Rating).
When the overload protection mode is activated, the
compressor operates for about 30 seconds to one minute
without raising the vehicle depending on the amount
of overload. This will continue each time the ignition
is turned on until the rear axle load is reduced
below GAWR.
Indicator Light
The indicator light on the inator switch in the rear
passenger compartment also serves as an indicator for
internal system error. If the indicator light is ashing
without the load leveling function or the inator being
active, turn off the ignition. The next day turn on the
ignition and check the indicator light. The vehicle can be
driven with the light ashing, but if it is, the vehicle should
be serviced as soon as possible.

Filling the Tank
{CAUTION:
Fuel vapor burns violently and a fuel re can
cause bad injuries. To help avoid injuries to you
and others, read and follow all the instructions on
the pump island. Turn off the engine when you are
refueling. Do not smoke if you are near fuel or
refueling the vehicle. Do not use cellular phones.
Keep sparks, ames, and smoking materials away
from fuel. Do not leave the fuel pump unattended
when refueling the vehicle. This is against the law
in some places. Do not re-enter the vehicle while
pumping fuel. Keep children away from the fuel
pump; never let children pump fuel.The tethered fuel cap is located behind a hinged fuel
door on the driver side of the vehicle.
To remove the fuel cap, turn it slowly counterclockwise.
While refueling, hang the tethered fuel cap from the
hook on the fuel door.
5-8

{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 the 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 5-113.
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 3-39.There may also be a light that comes on in the
instrument panel to let you know if the gas cap is
not properly installed. SeeCheck Gas Cap Light
on page 3-47for 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 the malfunction indicator
lamp to light and may damage the fuel tank and
emissions system. SeeMalfunction Indicator Lamp
on page 3-39.

How to Add Coolant to the Radiator
{CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
{CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and if you turn the surge tank
pressure cap — even a little — they can come out
at high speed. Never turn the cap when the cooling
system, including the surge tank pressure cap, is
hot. Wait for the cooling system and surge tank
pressure cap to cool if you ever have to turn the
pressure cap.If coolant is needed, add the proper mixture directly to
the radiator, but be sure the cooling system is cool
before this is done.
1. You can remove the radiator pressure cap when
the cooling system, including the radiator pressure
cap and upper radiator hose, is no longer hot.
Turn the pressure cap slowly counterclockwise
about one full turn. If you hear a hiss, wait for
that to stop. A hiss means there is still some
pressure left.
2. Then keep turning the pressure cap. Remove the
pressure cap.

3. Place the kit on the ground.
Make sure the tire valve stem is positioned close to
the ground so the hose will reach it.
4. Remove the valve stem cap from the at tire by
turning it counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valve
stem. Turn it clockwise until it is tight.
6. Plug the power plug (H) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets. SeeAccessory Power
Outlet(s) on page 3-19.
If the vehicle has an accessory power outlet, do not
use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.
7. Start the vehicle. The vehicle must be running while
using the air compressor.
8. Turn the selector switch (A) counterclockwise to the
Sealant + Air position.
9. Press the on/off (B) button to turn the tire sealant
and compressor kit on.
The compressor will inject sealant and air into
the tire.
The pressure gage (C) will initially show a high
pressure while the compressor pushes the sealant
into the tire. Once the sealant is completelydispersed into the tire, the pressure will quickly
drop and start to rise again as the tire inates
with air only.
10. Inate the tire to the recommended ination
pressure using the pressure gage (C).
The recommended ination pressure can
be found on the Tire and Loading Information
label. SeeInflation - Tire Pressure on page 5-65.
The pressure gage (C) may read higher than the
actual tire pressure while the compressor is on.
Turn the compressor off to get an accurate pressure
reading. The compressor may be turned on/off
until the correct pressure is reached.
Notice:If the recommended pressure cannot be
reached after approximately 25 minutes, the vehicle
should not be driven farther. The tire is too severely
damaged and the tire sealant and compressor kit
cannot inate the tire. Remove the power plug from
the accessory power outlet and unscrew the inating
hose from the tire valve. SeeRoadside Assistance
Program on page 7-7.
11. Press the on/off button (B) to turn the tire sealant
and compressor kit off.
The tire is not sealed and will continue to leak
air until the vehicle is driven and the sealant
is distributed in the tire, therefore, Steps 12 through
18 must be done immediately after Step 11.
Be careful while handling the tire sealant and
compressor kit as it could be warm after usage.
5-87

12. Unplug the power plug (H) from the accessory
power outlet in the vehicle.
13. Turn the sealant/air hose (F) counterclockwise to
remove it from the tire valve stem.
14. Replace the tire valve stem cap.
15. Replace the sealant/air hose (F), and the power
plug (H) back in their original location.
16. If the at tire was
able to inate to the
recommended ination
pressure, remove the
maximum speed label
from the sealant
canister (E) and place
it in a highly visible
location.
The label is a reminder not to exceed 55 mph
(90 km/h) until the damaged tire is repaired
or replaced.
17. Return the equipment to its original storage location
in the vehicle.
18. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant in the tire.19. Stop at a safe location and check the tire pressure.
Refer to Steps 1 through 11 under “Using the Tire
Sealant and Compressor Kit without Sealant to
Inate a Tire (Not Punctured).”
If the tire pressure has fallen more than 10 psi
(68 kPa) below the recommended ination pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant cannot seal the tire.
SeeRoadside Assistance Program on page 7-7.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, inate the tire to the recommended
ination pressure.
20. Wipe off any sealant from the wheel, tire, and
vehicle.
21. Dispose of the used sealant canister (E) and
sealant/air hose (F) assembly at a local dealer/
retailer or in accordance with local state codes
and practices.
22. Replace it with a new canister available from your
dealer/retailer.
23. After temporarily sealing a tire using the tire sealant
and compressor kit, take the vehicle to an authorized
dealer/retailer within a 100 miles (161 km) of driving
to have the tire repaired or replaced.
5-88

4. Remove the tire valve stem cap from the at tire by
turning it counterclockwise.
5. Attach the air only hose (G) onto the tire valve stem
by turning it clockwise until it is tight.
6. Plug the power plug (H) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets. SeeAccessory Power
Outlet(s) on page 3-19.
If the vehicle has an accessory power outlet, do not
use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.
7. Start the vehicle. The vehicle must be running while
using the air compressor.
8. Turn the selector switch (A) clockwise to the Air
Only position.
9. Press the on/off (B) button to turn the
compressor on.
The compressor will inate the tire with air only.10. Inate the tire to the recommended ination
pressure using the pressure gage (C). The
recommended ination pressure can be found
on the Tire and Loading Information label.
SeeInflation - Tire Pressure on page 5-65.
The pressure gage (C) may read higher than the
actual tire pressure while the compressor is on.
Turn the compressor off to get an accurate reading.
The compressor may be turned on/off until the
correct pressure is reached.
If you inate the tire higher than the recommended
pressure you can adjust the excess pressure
by pressing the pressure deation button (D),
if equipped, until the proper pressure reading
is reached. This option is only functional when
using the air only hose (G).
