Canadian Owners

You can obtain a French copy of this manual from your dealer or from:

Helm, Incorporated P.O. Box 07130 Detroit, MI 48207

GENERAL MOTORS, GM, the GM Emblem, CHEVROLET, the CHEVROLET Emblem and the name TRAILBLAZER/TRAILBLAZER EXT are registered trademarks of General Motors Corporation.

This manual includes the latest information at the time it was printed. We reserve the right to make changes after that time without further notice. For vehicles ﬁrst sold in Canada, substitute the name “General Motors of Canada Limited” for Chevrolet Motor Division whenever it appears in this manual.

Please keep this manual in your vehicle, so it will be there if you ever need it when you’re on the road. If you sell the vehicle, please leave this manual in it so the new owner can use it.

Litho in U.S.A. Part No. C2438 A First Edition

How to Use This Manual

Many people read their owner’s manual from beginning to end when they ﬁrst receive their new vehicle. If you do this, it will help you learn about the features and controls for your vehicle. In this manual, you will ﬁnd that pictures and words work together to explain things.

Index

A good place to look for what you need is the Index in back of the manual. It is an alphabetical list of what is in the manual, and the page number where you will ﬁnd it.

Safety Warnings and Symbols

You will ﬁnd a number of safety cautions in this book. We use a box and the word CAUTION to tell you about things that could hurt you if you were to ignore the warning.

{CAUTION:

These mean there is something that could hurt you or other people.

In the caution area, we tell you what the hazard is. Then we tell you what to do to help avoid or reduce the hazard. Please read these cautions. If you don’t, you or others could be hurt.

You will also ﬁnd a circle with a slash through it in this book. This safety symbol means “Don’t,” “Don’t do this” or “Don’t let this happen.”

iii

Vehicle Damage Warnings

Vehicle Symbols

Also, in this book you will ﬁnd these notices:

Notice: These mean there is something that could damage your vehicle.

A notice will tell you about something that can damage your vehicle. Many times, this damage would not be covered by your warranty, and it could be costly. But the notice will tell you what to do to help avoid the damage.

When you read other manuals, you might see CAUTION and NOTICE warnings in different colors or in different words.

You’ll also see warning labels on your vehicle. They use the same words, CAUTION or NOTICE.

Your vehicle has components and labels that use symbols instead of text. Symbols, used on your vehicle, are shown along with the text describing the operation or information relating to a speciﬁc component, control, message, gage or indicator.

If you need help ﬁguring out a speciﬁc name of a component, gage or indicator, reference the following topics:

• Seats and Restraint Systems in Section 1

• Features and Controls in Section 2

• Instrument Panel Overview in Section 3

• Climate Controls in Section 3

• Warning Lights, Gages and Indicators in Section 3

• Audio System(s) in Section 3

• Engine Compartment Overview in Section 5

These are some examples of symbols you may ﬁnd on your vehicle:

Manual Seats

{CAUTION:

You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you don’t want to. Adjust the driver’s seat only when the vehicle is not moving.

Pull up on the lever located under the front of the manual seat to unlock it. Slide the seat to where you want it and release the lever. Then try to move the seat with your body to make sure the seat is locked into place.

1-2

If you have this feature, the power seat controls are located on the outboard side of the front seat cushions. The horizontal control adjusts the seat cushion and the vertical control adjusts the seatback.

• Move the front of the seat control up or down to

adjust the front portion of the cushion.

• Move the rear of the seat control up or down to

adjust the rear portion of the cushion.

• Lift up or push down on the center of the seat

control to move the entire seat up or down.

• To move the seat forward or rearward, slide the

seat control forward or rearward.

• To recline the seatback, press the vertical control

rearward. To raise the seatback, press the vertical control forward.

Manual Lumbar

Heated Seats

Your vehicle may have this feature. This control is located on the outboard side of the seat.

Turn the knob counterclockwise to increase lumbar support and clockwise to decrease lumbar support.

Power Lumbar

Your vehicle may have this feature. The driver’s and passenger’s seatback lumbar support can be adjusted by moving a single control located on the outboard side of the seat cushions. To increase or decrease support, hold the control forward or rearward.

Keep in mind that as your seating position changes, as it may during long trips, so should the position of your lumbar support. Adjust the seat as needed.

Your vehicle may have heated front seats. The buttons used to control this feature are located on the front door armrests. The engine must be running for the heated seat feature to work.

To heat the entire seat, press the horizontal button with the heated seat symbol. Press the button repeatedly to cycle through the temperature settings of high, medium, low and off. The indicator lights will glow to designate the level of heat selected: three for high, two for medium and one for low. The low setting warms the seatback and cushion until the seat temperature is near body temperature. The medium and high settings heat the seatback and seat cushion to a slightly higher temperature. You will be able to feel heat in about two minutes.

1-3

To heat only the seatback, press the button with the words BACK ONLY. An indicator light on the switch will glow to designate that only the seatback is being heated. Additional presses will cycle through the heat levels for the seatback only. Press the horizontal button again to heat the whole seat.

The feature will shut off automatically when the ignition is turned off.

Reclining Seatbacks

If your vehicle has a manual recliner, lift the lever located on the outboard side of the seat and push the seatback rearward to recline the seatback. To return the seatback to the normal position, lift the lever without pushing rearward on the seatback and the seatback will move forward.

If your vehicle has power seat controls, the vertical power seat control described earlier allows the seatback to recline.

But don’t have a seatback reclined if your vehicle is moving.

1-4

{CAUTION:

Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can’t do their job when you’re reclined like this.

The shoulder belt can’t do its job. In a crash, you could go into it, receiving neck or other injuries.

The lap belt can’t do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries.

For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear your safety belt properly.

Head Restraints

Adjust your head restraint so that the top of the restraint is closest to the top of your head. This position reduces the chance of a neck injury in a crash.

The head restraints lock into place when raised. To release the head restraint and lower it, press the tab located on the top of the seatback.

1-5

Rear Seats

Rear Seat Operation

Your vehicle may have a folding rear seat which lets you fold the seatbacks down for more cargo space.

Pull up on the loop located where the seat cushion meets the seatback to fold the seat cushion up and out of the way. This will allow the seatback to fold ﬂat and increase the cargo area.

The rear seatback levers are located on the outboard side of the rear seatbacks.

Pull the seatback toward you as you lift up on the lever. The head restraint will automatically fold out of the way when the seatback is folded down.

To raise the seatbacks, lift up the seatbacks and push on them until they lock into the upright position. Push and pull on the seatbacks to make sure that they are latched securely. Then fold the bottom seat cushion back into place.

1-6

To return the head restraint to the upright position, reach behind the seat and pull the restraint up until it locks into place. Push and pull on the head restraint to make sure that it is latched securely.

Rear Seats (TrailBlazer EXT)

The second row seat is a 65/35 split seat which may be folded and tumbled. Use this feature for gaining access to the third row seats.

To fold and tumble the second row seat(s), do the following:

1. Push the head restraints fully down.

2. Fold the seatback ﬂat on the seat by pulling up on the front part of the fold and tumble lever. The lever is located on the outboard side of the seat (indicated as 1 on the handle side cover).

3. Release the rear set of seat hooks from the ﬂoor pins by pulling up on the rear part of the lever (indicated as 2 on the handle side cover). This enables the seat to be tumbled forward.

1-7

Returning the Seats to an Upright Position

To return the seat(s) to the upright position, do the following:

1. Pull the bottom of the seat release lever towards the front of the vehicle to release the seat. The lever is located at the bottom of the seat cushion on the outboard side of each second row seat.

2. Return the seat to the ﬂoor pins by rotating the seat down to reengage the seat hooks.

3. Try to raise the seat to check that it is locked down.

4. Pull the seat back up to return it to the upright position.

Entry/Exit to/from the Third Row Seat

To enter the third row seat, you must fold and tumble the second row seat following the instructions given previously.

If you are exiting the third row with no assistance, do the following.

1. Pull the handle on the center of the second row seatback down to release and fold the seatback.

2. Reach around to the side of the second row seat and pull the back of the seat lever up to tumble the entire seat.

Be sure to return the seat to the upright position when you are ﬁnished. Never use the third row as a seating position while the second row is folded and tumbled.

Folding the Third Row Seats

1. Pull up on the handle located on the bottom of the seat cushion to release the seat cushion.

2. Lift up the seat, and then pull it forward.

3. Fold the seatback forward until it is ﬂat.

4. Unhook the elastic loop on the back of the seatback.

5. Fold the panel located on the back of the seatback to make a ﬂat surface.

Returning the Seat(s) to an Upright Position

To return the seat to its original position, reverse the steps listed previously in folding the third row seats.

Safety Belts

Safety Belts: They Are for Everyone

This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts.

1-8

{CAUTION:

Don’t let anyone ride where he or she can’t wear a safety belt properly. If you are in a crash and you’re not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle or be ejected from it. You can be seriously injured or killed. In the same crash, you might not be, if you are buckled up. Always fasten your safety belt, and check that your passengers’ belts are fastened properly too.

{CAUTION:

It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do notallow people to ride in any area of your vehicle that is not equipped with seats and safety belts. Be sure everyone in your vehicle is in a seat and using a safety belt properly.

Your vehicle has a light that comes on as a reminder to buckle up. See

Safety Belt Reminder Light on page 3-35.

In most states and in all Canadian provinces, the law says to wear safety belts. Here’s why: They work.

You never know if you’ll be in a crash. If you do have a crash, you don’t know if it will be a bad one.

A few crashes are mild, and some crashes can be so serious that even buckled up, a person wouldn’t survive. But most crashes are in between. In many of them, people who buckle up can survive and sometimes walk away. Without belts they could have been badly hurt or killed.

After more than 30 years of safety belts in vehicles, the facts are clear. In most crashes buckling up does matter... a lot!

1-9

Why Safety Belts Work

When you ride in or on anything, you go as fast as it goes.

Take the simplest vehicle. Suppose it’s just a seat on wheels.

Put someone on it.

1-10

Get it up to speed. Then stop the vehicle. The rider doesn’t stop.

The person keeps going until stopped by something. In a real vehicle, it could be the windshield...

1-11

or the instrument panel... or the safety belts!

With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That’s why safety belts make such good sense.

1-12

Questions and Answers About Safety Belts

Q: Won’t I be trapped in the vehicle after an

accident if I’m wearing a safety belt?

A: You could be – whether you’re wearing a safety

belt or not. But you can unbuckle a safety belt, even if you’re upside down. And your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted.

Q: If my vehicle has air bags, why should I have to

wear safety belts?

A: Air bags are in many vehicles today and will be in

most of them in the future. But they are supplemental systems only; so they work with safety belts – not instead of them. Every air bag system ever offered for sale has required the use of safety belts. Even if you’re in a vehicle that has air bags, you still have to buckle up to get the most protection. That’s true not only in frontal collisions, but especially in side and other collisions.

Q: If I’m a good driver, and I never drive far from

home, why should I wear safety belts?

A: You may be an excellent driver, but if you’re in an

accident – even one that isn’t your fault – you and your passengers can be hurt. Being a good driver doesn’t protect you from things beyond your control, such as bad drivers.

Most accidents occur within 25 miles (40 km) of home. And the greatest number of serious injuries and deaths occur at speeds of less than 40 mph (65 km/h).

Safety belts are for everyone.

1-13

How to Wear Safety Belts Properly

This part is only for people of adult size. Be aware that there are special things to know about

safety belts and children. And there are different rules for smaller children and babies. If a child will be riding in your vehicle, see Older Children on page 1-28 or Infants and Young Children on page 1-31. Follow those rules for everyone’s protection.

First, you’ll want to know which restraint systems your vehicle has.

We’ll start with the driver position.

Driver Position

This part describes the driver’s restraint system.

Lap-Shoulder Belt

The driver has a lap-shoulder belt. Here’s how to wear it properly.

1. Close and lock the door.

2. Adjust the seat so you can sit up straight. To see how, see “Seats” in the Index.

3. Pick up the latch plate and pull the belt across you. Don’t let it get twisted.

4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure.

If the belt isn’t long enough, see Safety Belt Extender on page 1-28.

Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.

1-14

5. To make the lap part tight, pull up on the shoulder belt.

The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces.

The safety belt locks if there’s a sudden stop or crash, or if you pull the belt very quickly out of the retractor.

1-15

Q: What’s wrong with this?

A: The shoulder belt is too loose. It won’t give nearly

as much protection this way.

{CAUTION:

You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should ﬁt against your body.

1-16

Q: What’s wrong with this?

A: The belt is buckled in the wrong place.

{CAUTION:

You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you.

1-17

Q: What’s wrong with this?

A: The shoulder belt is worn under the arm. It should

be worn over the shoulder at all times.

{CAUTION:

You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which aren’t as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen.

1-18

Q: What’s wrong with this?

A: The belt is twisted across the body.

{CAUTION:

You can be seriously injured by a twisted belt. In a crash, you wouldn’t have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer to ﬁx it.

1-19

To unlatch the belt, just push the button on the buckle. The belt should go back out of the way.

Before you close the door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle.

Safety Belt Use During Pregnancy

Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they don’t wear safety belts.

A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy.

1-20

The best way to protect the fetus is to protect the mother. When a safety belt is worn properly, it’s more likely that the fetus won’t be hurt in a crash. For pregnant women, as for anyone, the key to making safety belts effective is wearing them properly.

Right Front Passenger Position

To learn how to wear the right front passenger’s safety belt properly, see Driver Position on page 1-14.

The right front passenger’s safety belt works the same way as the driver’s safety belt – except for one thing. If you ever pull the shoulder portion of the belt out all the way, you will engage the child restraint locking feature. If this happens, just let the belt go back all the way and start again.

Rear Seat Passengers

It is very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts.

Rear passengers who are not safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts.

Rear Seat Passenger Positions

1-21

Lap-Shoulder Belt

All rear seating positions have lap-shoulder belts. Here is how to wear one properly.

1. Pick up the latch plate and pull the belt across you. Do not let it get twisted.

2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure.

When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again. If the belt is not long enough, see Safety Belt Extender on page 1-28.

Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.

3. To make the lap part tight, pull up on the shoulder part.

1-22

The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash this applies force to the strong pelvic bones. And you would be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces.

{CAUTION:

You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should ﬁt against your body.

1-23

To unlatch the belt, just push the button on the buckle.

Rear Safety Belt Comfort Guides for Children and Small Adults

Rear shoulder belt comfort guides provide added safety belt comfort for older children who have outgrown booster seats and for small adults. When attached to a shoulder belt, the comfort guide better positions the belt away from the neck and head.

There is one guide for each of the rear outside passenger positions. Here is how to attach the comfort guide to the shoulder belt.
