sensing and diagnostic module, and
airbag wiring along with the proper
replacement procedures.
In addition, the vehicle has a
passenger sensing system for the front
outboard passenger position, which
includes sensors that are part of the
passenger seat. The passenger sensing
system may not operate properly if
the original seat trim is replaced with
non-GM covers, upholstery, or trim; or
with GM covers, upholstery, or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort-enhancing pad or
device, installed under or on top of
the seat fabric, could also interfere
with the operation of the passenger
sensing system. This could either
prevent proper deployment of the
passenger airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). SeePassenger Sensing
System 061.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0342 for additional important
information. If the vehicle must be modified
because you have a disability and have
questions about whether the
modifications will affect the vehicle's
airbag system, or if you have
questions about whether the airbag
system will be affected if the vehicle is
modified for any other reason, call
Customer Assistance. See
Customer
Assistance Offices 0394.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See Airbag
Readiness Light 0107.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag may
not work properly. Do not open or
break the airbag coverings. If there
are any opened or broken airbag
coverings, have the airbag covering
and/or airbag module replaced. For
the location of the airbags, see
Where Are the Airbags? 057. See
your dealer for service.
Replacing Airbag System
Parts after a Crash
{Warning
A crash can damage the airbag
systems in the vehicle. A damaged
airbag system may not properly
protect you and your passenger(s)
in a crash, resulting in serious
injury or even death. To help make
sure the airbag systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.
If an airbag inflates, you will need to
replace airbag system parts. See your
dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See

Driving Information
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.
.On AWD vehicles, use Tour Mode
when conditions permit.
.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.

Tire and Loading Information Label
Example Label
A vehicle-specific Tire and
Loading Information label is
attached to the center pillar
(B-pillar). The tire and loading
information label shows the
number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading Information
label also shows the size of the
original equipment tires (3) and
the recommended cold tireinflation pressures (4). For more
information on tires and inflation
see
Tires 0325 and
Tire Pressure 0331.
There is also important loading
information on the vehicle
Certification/Tire label. It may
show the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle
Weight Rating (GAWR) for the
front and rear axle. See
“Certification/Tire Label” later in
this section.“Steps for Determining Correct Load
Limit–
1.
Locate the statement "The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs." on your
vehicle’s placard.
2.Determine the combined weight
of the driver and passengers
that will be riding in your
vehicle.
3.Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lbs.
4.The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the "XXX" amount
equals 1400 lbs. and there will
be five 150 lb passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) = 650 lbs.)
5.Determine the combined weight
of luggage and cargo being
loaded on the vehicle. That
weight may not safely exceed
the available cargo and luggage
load capacity calculated in
Step 4.
6.If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your
vehicle. Consult this manual to

DRIVING AND OPERATING 223
weight of the driver, passengers,
and cargo should never exceed the
vehicle's capacity weight.
Certification/Tire Label
Label Example
A vehicle-specific Certification/
Tire label is attached to the center
pillar (B-pillar).
The label may show the size of the
vehicle's original tires and the
inflation pressures needed to
obtain the gross weight capacity
of the vehicle. The label shows the
gross weight capacity of the
vehicle. This is called the GrossVehicle Weight Rating (GVWR).
The GVWR includes the weight of
the vehicle, all occupants, fuel,
and cargo.
The Certification/Tire label may
also show the maximum weights
for the front and rear axles, called
the Gross Axle Weight Rating
(GAWR). To find out the actual
loads on the front and rear axles,
weigh the vehicle at a weigh
station. Your dealer can help with
this. Be sure to spread the load
equally on both sides of the
centerline.
CautionOverloading the vehicle may cause
damage. Repairs would not be
covered by the vehicle warranty. Do
not overload the vehicle.
{Warning
Things inside the vehicle can
strike and injure people in a
sudden stop or turn, or in a
crash.
.Put things in the cargo area
of the vehicle. In the cargo
area, put them as far forward
as possible. Try to spread the
weight evenly.
.Never stack heavier things,
like suitcases, inside the
vehicle so that some of them
are above the tops of the
seats.
.Do not leave an unsecured
child restraint in the vehicle.
.Secure loose items in the
vehicle.
.Do not leave a seat folded
down unless needed.

all-season tires can be identified by
the last two characters of this TPC
code, which will be“MS.”
Consider installing winter tires on the
vehicle if frequent driving on snow or
ice-covered roads is expected.
All-season tires provide adequate
performance for most winter driving
conditions, but they may not offer the
same level of traction or performance
as winter tires on snow or ice-covered
roads. See Winter Tires 0326.
Winter Tires
This vehicle was not originally
equipped with winter tires. Winter
tires are designed for increased
traction on snow and ice-covered
roads. Consider installing winter tires
on the vehicle if frequent driving on
ice or snow covered roads is expected.
See your dealer for details regarding
winter tire availability and proper tire
selection. Also, see Buying New Tires
0 341.
With winter tires, there may be
decreased dry road traction, increased
road noise, and shorter tread life. After changing to winter tires, be alert
for changes in vehicle handling and
braking.
If using winter tires:
.Use tires of the same brand and
tread type on all four wheel
positions.
.Use only radial ply tires of the same
size, load range, and speed rating as
the original equipment tires.
Winter tires with the same speed
rating as the original equipment tires
may not be available for H, V, W, Y,
and ZR speed rated tires. If winter
tires with a lower speed rating are
chosen, never exceed the tire's
maximum speed capability.
Summer Tires
This vehicle may come with
235/65R18 or 235/55R20 high
performance summer tires. These tires
have a special tread and compound
that are optimized for maximum dry
and wet road performance. This
special tread and compound will have
decreased performance in cold
climates, and on ice and snow. It is
recommended that winter tires be installed on the vehicle if frequent
driving at temperatures below
approximately 5 °C (40 °F) or on ice or
snow covered roads is expected. See
Winter Tires
0326.
Caution
High performance summer tires
have rubber compounds that lose
flexibility and may develop surface
cracks in the tread area at
temperatures below −7 °C (20 °F).
Always store high performance
summer tires indoors and at
temperatures above −7 °C (20 °F)
when not in use. If the tires have
been subjected to −7 °C (20 °F) or
less, let them warm up in a heated
space to at least 5 °C (40 °F) for
24 hours or more before being
installed or driving a vehicle on
which they are installed. Do not
apply heat or blow heated air
directly on the tires. Always inspect
tires before use. See Tire Inspection
0 338.
