2007 CADILLAC STS weight

Treadwear Indicators:Narrow bands, sometimes
called wear bars, that show across the tread of a
tire when only 1/16 inch (1.6 mm) of tread remains.
SeeWhen It Is Time for New Tires on page 440.
UTQGS (Uniform Tire Quality Grading
Standards):A tire information system that
provides consumers with ratings for a tire’s
traction, temperature, and treadwear. Ratings are
determined by tire manufacturers using
government testing procedures. The ratings are
molded into the sidewall of the tire. SeeUniform
Tire Quality Grading on page 444.
Vehicle Capacity Weight:The number of
designated seating positions multiplied by 150 lbs
(68 kg) plus the rated cargo load. SeeLoading
Your Vehicle on page 349.
Vehicle Maximum Load on the Tire:Load on an
individual tire due to curb weight, accessory
weight, occupant weight, and cargo weight.
Vehicle Placard:A label permanently attached to
a vehicle showing the vehicle’s capacity weight
and the original equipment tire size and
recommended ination pressure. See “Tire and
Loading Information Label” underLoading
Your Vehicle on page 349.Run-Flat Tires (STS-V)
If your vehicle has run-at tires, there is no spare
tire and no tire changing equipment. Your
vehicle also has a Tire Pressure Monitor
System (TPMS) which will alert you if there is a
loss of tire pressure in any of the tires. See
Tire Pressure Monitor System on page 433.
{CAUTION:
When the low tire warning light is
displayed on the instrument panel cluster,
your vehicle’s handling capabilities will be
reduced during severe maneuvers. If you
drive too fast, you could lose control of
your vehicle. You or others could be
injured. Do not drive over 55 mph
(90 km/h) when the low tire warning light
is displayed. Drive cautiously and check
your tire pressures as soon as you can.

Ination - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under-ination or over-ination is all right. It is
not. If your tires do not have enough air
(under-ination), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazardsA Tire and Loading Information label is attached to
the vehicle’s center pillar, below the driver’s
door latch. This label lists your vehicle’s original
equipment tires and shows the correct ination
pressures for your tires when they are cold. The
recommended cold tire ination pressure,
shown on the label, is the minimum amount of air
pressure needed to support your vehicle’s
maximum load carrying capacity.
For additional information regarding how much
weight your vehicle can carry, and an example of
the tire and loading information label, see
Loading Your Vehicle on page 349. How you load
your vehicle affects vehicle handling and ride
comfort, never load your vehicle with more weight
than it was designed to carry.
When to Check
Check your tires once a month or more. Do not
forget to check the compact spare tire, if your
vehicle has one. The compact spare should be at
60 psi (420 kPa). For additional information
regarding the compact spare tire, seeCompact
Spare Tire on page 475.

{CAUTION:
Raising your vehicle with the jack
improperly positioned can damage the
vehicle and even make the vehicle fall. To
help avoid personal injury and vehicle
damage, be sure to place the jack in the
proper location before raising the vehicle.
If you ever use a jack to lift your vehicle, follow
the instructions that came with the jack, and
be sure to use the correct lifting points to avoid
damaging your vehicle.Notice:Lifting your vehicle improperly can
damage your vehicle and result in costly repairs
not covered by your warranty. To lift your
vehicle properly, follow the advice in this part.
To help prevent vehicle damage:
Be sure the jack you are using meets the
weight standards for your vehicle and is
in good working order.
Be sure to place a block or pad between
the jack and the vehicle.
Make sure the jack you are using only
contacts the jacking location lift points and
is not leaning on any other vehicle
components such as the rocker panels, the
oor pan, or the stone guard moldings.
Lift only in the areas shown in the following
pictures.
