system may run when the vehicle is started
remotely. The system uses the driver’s
previous settings to heat or cool the inside
of the vehicle. The rear defog may come on
during remote start based on cold ambient
conditions. If the vehicle has heated seats, they may come on during a remote start.
See
Remote Vehicle Start 017 and
Heated Front Seats 040.
Sensors
The solar sensor on top of the instrument
panel near the windshield monitors the solar
heat. The climate control system uses the
sensor information to adjust the
temperature, fan speed, recirculation, and air
delivery mode for best comfort.
Do not cover the sensor; otherwise the
automatic climate control system may not
work properly.
Air Vents
Use the louvers located on the air vents to
change the direction of the airflow.
To open or close off the airflow:
.Move slider knobs away from the
occupant for shut off closing.
Operation Tips
.Clear away any ice, snow, or leaves from
air inlets at the base of the windshield
that could block the flow of air into the
vehicle.
.Clear snow off the hood to improve
visibility and help decrease moisture
drawn into the vehicle, which may
improve long term system performance.
.Keep the path under the front seats clear
of objects to help circulate the air inside
of the vehicle more effectively.
.Use of non-GM approved hood deflectors
can adversely affect the performance of
the system. Check with your dealer
before adding equipment to the outside
of the vehicle.
.Do not attach any devices to the air vent
slats. This restricts airflow and may cause
damage to the air vents.
Caution
Use of air fresheners may cause
permanent damage to plastics and
painted surfaces. If an air freshener
comes in contact with any plastic or
painted surface in the vehicle, blot
immediately and clean with a soft cloth
dampened with a mild soap solution.
Damage caused by air fresheners would
not be covered by the vehicle warranty.

Maintenance
Passenger Compartment Air Filter
The filter reduces dust, pollen, and other
airborne irritants from outside air that is
pulled into the vehicle. The filter should
be replaced as part of routine scheduled
maintenance.
SeeMaintenance Schedule 0316.
See your dealer regarding replacement of
the filter.
Service
All vehicles have a label underhood that
identifies the refrigerant used in the vehicle.
The refrigerant system should only be
serviced by trained and certified technicians.
The air conditioning evaporator should
never be repaired or replaced by one from a
salvage vehicle. It should only be replaced
by a new evaporator to ensure proper and
safe operation.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere is
harmful to the environment and may also create unsafe conditions based on
inhalation, combustion, frostbite, or other
health-based concerns.
The air conditioning system requires periodic
maintenance. See
Maintenance Schedule
0 316.
Caution
Use only correct Refrigerant and A/C
Compressor Oil shown in Label.

Driving Information
Driver Behavior
Driving is an important responsibility. Driver
behavior, the driving environment, and the
vehicle's design all affect how well a vehicle
performs.
Being aware of these factors can help in
understanding how the vehicle handles and
what can be done to avoid many types of
crashes, including a rollover crash.
Most serious injuries and fatalities to
unbelted occupants can be reduced or
prevented by the use of seat belts. In a
rollover crash, an unbelted person is
significantly more likely to die than a
person wearing a seat belt. In addition,
avoiding excessive speed, sudden or abrupt
turns, and drunken or aggressive driving can
help make trips safer and avoid the
possibility of a crash.
Driving Environment
Be prepared for driving in inclement
weather, at night, or during other times
where visibility or traction may be limited, such as on curves, slippery roads, or hilly
terrain. Unfamiliar surroundings can also
have hidden hazards.
Vehicle Design
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
This is because they have a higher ground
clearance and a narrower track or shorter
wheelbase than passenger cars. While these
design characteristics provide the driver with
a better view of the road, these vehicles do
have a higher center of gravity than other
types of vehicles. A utility vehicle does not
handle the same as a vehicle with a lower
center of gravity, like a car, in similar
situations.
Safe driver behavior and understanding of
the environment can help avoid a rollover
crash in any type of vehicle, including utility
vehicles.
Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here
are some driving tips to get the best fuel
economy possible.
.Set the climate controls to the desired
temperature after the engine is started,
or turn them off when not required.

Chevrolet Trailblazer Owner Manual (GMNA-Localizing-U.S./Canada-
14400528) - 2021 - CRC - 11/7/19
182 Driving and Operating
.On AWD vehicles, seeDriver Mode Control
0 208.
.Avoid fast starts and accelerate smoothly.
.Brake gradually and avoid abrupt stops.
.Avoid idling the engine for long periods
of time.
.When road and weather conditions are
appropriate, use cruise control.
.Always follow posted speed limits or
drive more slowly when conditions
require.
.Keep vehicle tires properly inflated.
.Combine several trips into a single trip.
.Replace the vehicle's tires with the same
TPC Spec number molded into the tire's
sidewall near the size.
.Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms and can
take your focus from the task of driving.
Exercise good judgment and do not let other
activities divert your attention away from
the road. Many local governments have
enacted laws regarding driver distraction.
Become familiar with the local laws in
your area. To avoid distracted driving, keep your eyes
on the road, keep your hands on the
steering wheel, and focus your attention on
driving.
.Do not use a phone in demanding driving
situations. Use a hands-free method to
place or receive necessary phone calls.
.Watch the road. Do not read, take notes,
or look up information on phones or
other electronic devices.
.Designate a front seat passenger to
handle potential distractions.
.Become familiar with vehicle features
before driving, such as programming
favorite radio stations and adjusting
climate control and seat settings. Program
all trip information into any navigation
device prior to driving.
.Wait until the vehicle is parked to
retrieve items that have fallen to the
floor.
.Stop or park the vehicle to tend to
children.
.Keep pets in an appropriate carrier or
restraint.
.Avoid stressful conversations while
driving, whether with a passenger or on a
cell phone.
{Warning
Taking your eyes off the road too long or
too often could cause a crash resulting in
injury or death. Focus your attention on
driving.
Refer to the infotainment section for more
information on using that system and the
navigation system, if equipped, including
pairing and using a cell phone.
Defensive Driving
Defensive driving means “always expect the
unexpected.” The first step in driving
defensively is to wear the seat belt. See
Seat Belts 044.
.Assume that other road users
(pedestrians, bicyclists, and other drivers)
are going to be careless and make
mistakes. Anticipate what they may do
and be ready.
.Allow enough following distance between
you and the driver in front of you.
.Focus on the task of driving.
Impaired Driving
Death and injury associated with impaired
driving is a global tragedy.

14400528) - 2021 - CRC - 11/7/19
Driving and Operating 183
{Warning
Drinking alcohol or taking drugs and then
driving is very dangerous. Your reflexes,
perceptions, attentiveness, and judgment
can be affected by even a small amount
of alcohol or drugs. You can have a
serious—or even fatal —collision if you
drive after drinking or taking drugs.
Do not drive while under the influence of
alcohol or drugs, or ride with a driver
who has been drinking or is impaired by
drugs. Find alternate transportation
home; or if you are with a group,
designate a driver who will remain sober.
Control of a Vehicle
Braking, steering, and accelerating are
important factors in helping to control a
vehicle while driving.
Braking
Braking action involves perception time and
reaction time. Deciding to push the brake
pedal is perception time. Actually doing it is
reaction time. Average driver reaction time is about
three-quarters of a second. In that time, a
vehicle moving at 100 km/h (60 mph) travels
20 m (66 ft), which could be a lot of
distance in an emergency.
Helpful braking tips to keep in mind include:
.Keep enough distance between you and
the vehicle in front of you.
.Avoid needless heavy braking.
.Keep pace with traffic.
If the engine ever stops while the vehicle is
being driven, brake normally but do not
pump the brakes. Doing so could make the
pedal harder to push down. If the engine
stops, there will be some power brake assist
but it will be used when the brake is
applied. Once the power assist is used up, it
can take longer to stop and the brake pedal
will be harder to push.
Steering
Electric Power Steering
Caution
To avoid damage to the steering system,
do not drive over curbs, parking barriers,
or similar objects at speeds greater than
(Continued)
Caution (Continued)
3 km/h (1 mph). Use care when driving
over other objects such as lane dividers
and speed bumps. Damage caused by
misuse of the vehicle is not covered by
the vehicle warranty.
The vehicle has electric power steering.
It does not have power steering fluid.
Regular maintenance is not required.
If power steering assist is lost due to a
system malfunction, the vehicle can be
steered, but may require increased effort.
If the steering assist is used for an extended
period of time while the vehicle is not
moving, power assist may be reduced.
