Temperature Warning
Light
The engine coolant temperature
light should come on briey as the
engine is started. If it does not
come on have the vehicle serviced
by your dealer/retailer.
Notice:Driving with the engine
coolant temperature warning light
on could cause the vehicle to
overheat. SeeEngine Overheating
on page 9-18. The vehicle’s engine
could be damaged, and it might
not be covered by the vehicle
warranty. Never drive with the
engine coolant temperature
warning light on.
If this light comes on and stays on,
the engine has overheated. Pull
over and seeEngine Overheating on
page 9-18for more information.
Tire Pressure Light
For vehicles with this light, it comes
on briey as a check when the
ignition is turned on.
This light comes on and stays on
when one or more of the vehicle’s
tires are signicantly underinated.
Stop and check the tires as
soon as it is safe to do so.
If underinated, inate to the proper
pressure. SeeTires on page 9-40
for more information.
This light ashes for approximately
one minute and then stays on
when the system detects a
malfunction. SeeTire Pressure
Monitor System on page 9-49for
more information.
Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It makes sure
that emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.
This light should come on when
the ignition is on, but the engine
is not running, as check to show
it is working. If it does not, have
the vehicle serviced by your
dealer/retailer.

The Tire and Loading
Information label also shows the
tire size of the original equipment
tires (C) and the recommended
cold tire ination pressures (D).
For more information on tires and
ination seeTires on page 9-40
andInflation - Tire Pressure on
page 9-47.
There is also important loading
information on the Certication
label. It tells you the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight
Rating (GAWR) for the front and
rear axle; see “Certication
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 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 gure equals
the available amount of cargo
and luggage load capacity.
For example, if the “XXX”
amount equals 1400 lbs
and there will be ve 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, the load from your
trailer will be transferred to
your vehicle. Consult this
manual to determine how this
reduces the available cargo
and luggage load capacity of
your vehicle.
The vehicle is neither designed
nor intended to tow a trailer.

Tires
Your new vehicle comes with
high-quality tires made by
a leading tire manufacturer.
If you ever have questions about
the tire warranty and where to
obtain service, see the “Limited
Warranty, Maintenance and
Owner Assistance Information”
manual for details. For additional
information refer to the tire
manufacturer.{CAUTION
Poorly maintained and
improperly used tires are
dangerous.
Overloading your tires can
cause overheating as a
result of too much exing.
You could have an air-out
and a serious accident.
SeeLoading the Vehicle
on page 8-30.
Underinated tires pose
the same danger as
overloaded tires.
The resulting accident
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when
your tires are cold. See
Inflation - Tire Pressure on
page 9-47.
(Continued)
CAUTION (Continued)
Overinated tires are more
likely to be cut, punctured,
or broken by a sudden
impact — such as when
you hit a pothole. Keep
tires at the recommended
pressure.
Worn, old tires can cause
accidents. If your tread is
badly worn, or if your tires
have been damaged,
replace them.
SeeHigh-Speed Operation
on page 9-48for ination
pressure adjustment for high
speed driving.

Low-Prole Tires
If the vehicle has 225/40ZR18 or
215/45R18 size tires, they
are classied as low-prole
performance tires. These tires
are designed for very responsive
driving on wet or dry pavement.
You may also notice more
road noise with low-prole
performance tires and that they
tend to wear faster.
Notice:If the vehicle has
low-prole tires, they are more
susceptible to damage from
road hazards or curb impact
than standard prole tires.
Tire and/or wheel assembly
damage can occur when
coming into contact with road
hazards like, potholes, or
sharp edged objects, or when
sliding into a curb. The vehicle
warranty does not cover this
type of damage. Keep tires
set to the correct inationpressure and, when possible
avoid contact with curbs,
potholes, and other road
hazards.
Winter Tires
If the vehicle has 225/40ZR18 or
215/45R18 size tires, they are
classied as low-prole performance
tires. These tires are designed for
very responsive driving on wet or dry
pavement. If you expect to drive
on snow or ice covered roads often,
you may want to get winter tires
for your vehicle. All season tires
provide good overall performance on
most surfaces but they may not
offer the traction you would like or
the same level of performance
as winter tires on snow or ice
covered roads.
Winter tires, in general, are
designed for increased traction
on snow and ice covered roads.With winter tires, there may be
decreased dry road traction,
increased road noise, and shorter
tire tread life. After switching to
winter tires, be alert for changes in
vehicle handling and braking.
See your dealer/retailer for details
regarding winter tire availability
and proper tire selection. Also, see
Buying New Tires on page 9-54.
If you choose to use 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 your 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 you choose winter tires with a
lower speed rating, never exceed
the tire’s maximum speed capability.

Tire Sidewall Labeling
Useful information about a tire
is molded into its sidewall.
The examples below show a
typical passenger vehicle tire and
a compact spare tire sidewall.
(A) Tire Size
:The tire size is
a combination of letters and
numbers used to dene a
particular tire’s width, height,
aspect ratio, construction type,
and service description.See the “Tire Size” illustration
later in this section for more
detail.
(B) TPC Spec (Tire
Performance Criteria
Specication)
:Original
equipment tires designed to
GM’s specic tire performance
criteria have a TPC specication
code molded onto the sidewall.
GM’s TPC specications meet
or exceed all federal safety
guidelines.
(C) DOT (Department of
Transportation)
:The
Department of Transportation
(DOT) code indicates that
the tire is in compliance with
the U.S. Department of
Transportation Motor Vehicle
Safety Standards.
(D) Tire Identication Number
(TIN)
:The letters and numbers
following DOT (Department
of Transportation) code is the
Tire Identication Number (TIN).The TIN shows the manufacturer
and plant code, tire size, and
date the tire was manufactured.
The TIN is molded onto both
sides of the tire, although only
one side may have the date
of manufacture.
(E) Tire Ply Material
:The type
of cord and number of plies in the
sidewall and under the tread.
(F) Uniform Tire Quality
Grading (UTQG)
:Tire
manufacturers are required to
grade tires based on three
performance factors: treadwear,
traction, and temperature
resistance. For more information
seeUniform Tire Quality
Grading on page 9-57.
(G) Maximum Cold Ination
Load Limit
:Maximum load
