294 Vehicle Care
If a tire goes flat, avoid further tire and
wheel damage by driving slowly to a level
place, well off the road, if possible. Turn on
the hazard warning flashers. SeeHazard
Warning Flashers 0115.
If your vehicle is loaded at or near
maximum cargo capacity, it may be difficult
to fit the jack under the vehicle due to the
environment (shoulder slope, road debris,
etc.). Removal of some weight may improve
the ability to fit the jack under the vehicle
at the correct jacking location.
{Warning
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall causing injury or death. Find a
level place to change the tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the vehicle in P (Park).
3. Turn the vehicle off and do not restart the vehicle while it is raised.
4. Do not allow passengers to remain in the vehicle.

grounding point is the engine block or an
engine mounting bolt. Connect to a spot as
far away from the discharged battery as
possible. The good battery negative (–) terminal and
good battery positive (+) terminal are on
the battery of the vehicle providing the
jump start.
The discharge battery positive (+) terminal is
under a trim cover. Open the cover to
expose the terminal.
1. Check the other vehicle. It must have a 12-volt battery with a negative ground
system.
Caution
If the other vehicle does not have a
12-volt system with a negative ground,
both vehicles can be damaged. Only use
a vehicle that has a 12-volt system with a
negative ground for jump starting.
2. Position the two vehicles so that they are not touching.
3. Set the parking brake firmly and put the shift lever in P (Park) with an automatic
transmission, or Neutral with a manual
transmission.
Caution
If any accessories are left on or plugged
in during the jump starting procedure,
they could be damaged. The repairs
would not be covered by the vehicle
warranty. Whenever possible, turn off or
unplug all accessories on either vehicle
when jump starting.
4. Turn the ignition off. Turn off all lights and accessories in both vehicles, except
the hazard warning flashers if needed.
{Warning
An electric fan can start up even when
the engine is not running and can injure
you. Keep hands, clothing, and tools
away from any underhood electric fan.
{Warning
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a flashlight if you need
more light.

battery negative (–) grounding point. 9. Start the engine in the vehicle with the
good battery and run the engine at idle
speed for at least four minutes.
10. Try to start the vehicle that had the dead battery. If it will not start after a
few tries, it probably needs service.
Caution
If the jumper cables are connected or
removed in the wrong order, electrical
shorting may occur and damage the
vehicle. The repairs would not be covered
by the vehicle warranty. Always connect
and remove the jumper cables in the
correct order, making sure that the cables
do not touch each other or other metal.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle and
removing the jumper cables, allow it to idle
for several minutes.
Towing the Vehicle
Transporting a Disabled Vehicle
Caution
Incorrectly transporting a disabled vehicle
may cause damage to the vehicle. Use
proper tire straps to secure the vehicle to
the flatbed tow truck. Do not strap or
hook to any frame, underbody,
or suspension component not specified
below. Do not move vehicles with drive
axle tires on the ground. Damage is not
covered by the vehicle warranty.
Caution
The vehicle may be equipped with an
electric parking brake and/or a
mechanical transmission range select
shifter. In the event of a loss of 12-volt
battery power, the electric parking brake
cannot be released, and the vehicle
cannot be shifted to N (Neutral). Tire

loading/unloading the vehicle. Dragging
the vehicle will cause damage not
covered by the vehicle warranty.
Caution
The vehicle may be equipped with a tow
eye. Improper use of the tow eye may
cause damage to the vehicle and is not
covered by the vehicle warranty.
If equipped, use the tow eye to load the
vehicle onto a flatbed tow truck from a
flat road surface, or to move the vehicle
a very short distance at a walking pace.
The tow eye is not designed for off-road
recovery. The vehicle must be in
N (Neutral) with the electric parking
brake released when using the tow eye.
Contact a professional towing service if the
disabled vehicle must be transported. GM
recommends a flatbed tow truck to
transport a disabled vehicle. Use ramps to
help reduce approach angles, if necessary. If equipped, a tow eye may be located near
the spare tire or emergency jack. Do not use
the tow eye to pull the vehicle from the
snow, mud, sand, or ditch. Tow eye threads
may have right or left-hand threads. Use
caution when installing or removing the
tow eye.
The vehicle must be in N (Neutral) and the
electric parking brake must be released
when loading the vehicle onto a flatbed tow
truck.
.If the 12-volt battery is dead and/or
electric parking brake is not released, the
vehicle will not move. Try to jump start
the vehicle with a known good 12-volt
battery, shift the car into N (Neutral), and
release the electric parking brake. Refer to
Jump Starting - North America
0299.
.If unsuccessful, the vehicle will not move.
Tire skates or dollies must be used under
the non-rolling tires to prevent vehicle
damage.
Front Attachment Points
The vehicle is equipped with specific
attachment points to be used by the towing
provider. These holes may be used to pull
the vehicle from a flat road surface onto the
flatbed tow truck.
Recreational Vehicle Towing
Recreational vehicle towing means towing
the vehicle behind another vehicle, such as
behind a motor home. The two most
common types of recreational vehicle
towing are known as dinghy towing and
dolly towing. Dinghy towing is towing the
vehicle with all four wheels on the ground.

Chevrolet Trailblazer Owner Manual (GMNA-Localizing-U.S./Canada-
16263960) - 2023 - CRC - 2/23/22
Vehicle Care 303
Dolly towing is towing the vehicle with two
wheels on the ground and two wheels up
on a device known as a dolly.
Here are some important things to consider
before recreational vehicle towing:
.What is the towing capacity of the
towing vehicle? Be sure to read the tow
vehicle manufacturer's recommendations.
.What is the distance that will be
traveled? Some vehicles have restrictions
on how far and how long they can tow.
.Is the proper towing equipment going to
be used? See your dealer or trailering
professional for additional advice and
equipment recommendations.
.Is the vehicle ready to be towed? Just as
preparing the vehicle for a long trip,
make sure the vehicle is prepared to be
towed.
Caution
Use of a shield mounted in front of the
vehicle grille could restrict airflow and
cause damage to the transmission. The
repairs would not be covered by the
vehicle warranty. If using a shield, only
use one that attaches to the towing
vehicle.
Dinghy Towing (Front-Wheel-Drive
