2007 CADILLAC XLR V spare tire

System Conguration
This feature allows you to recongure the
navigation system. If you begin to drive your
vehicle during this procedure, the system will not
be able to adjust the position or direction of
your vehicle.
Touch the System Conguration screen button to
view the following choices:
Adjust Vehicle Position:To correct the position
of your vehicle on the map or to change vehicle
position, do the following:
1. Touch the Adjust Vehicle Position screen
button. The system will display Position
Adjustment. The vehicle location symbol and
the scroll symbol will appear on the map.
2. Use the scroll symbol and the zoom in/zoom
out feature to locate the vehicle position on
the map.
3. Touch Enter to set the vehicle position. The
system will display Position Adjustment and
two arrows will appear on the map screen.
4. Touch the arrows to adjust the direction of the
vehicle. As you touch the arrows, you will see
the vehicle symbol direction changing.5. When you have set the vehicle to the correct
direction, touch Enter. Relocation Complete
will be displayed.
6. Touch Return to exit this menu.
Calibrate Vehicle Speed Signal:If there are tire
pressure differences or if a spare tire is installed,
the navigation system will automatically recalibrate
the system. You may also choose to calibrate it
yourself by doing the following:
1. Touch Start to begin calibration.
2. Touch Return to exit this menu.
Time to Destination
This feature allows you to view the estimated time
to travel from your current position to the
destination, and to reset the average speed to
factory default settings. Estimated travel time
is based on calculated route information and the
vehicle’s average speed. Touch ON to turn
this feature on, OFF to turn this feature off, or
Reset to restore vehicle speed default settings.
With this feature on, the estimated travel time
to destination will display along with the distance
to destination.

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 354.
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 354.
Run-Flat Tires
Your vehicle, when new, had run-at tires. There
is no spare tire, no tire changing equipment,
and no place to store a tire in the vehicle. Run-at
tires perform so well without any air that a Tire
Pressure Monitor (TPM) is used to alert you
if a tire has lost pressure.If a tire goes at, you will not need to stop on the
side of the road to change the tire. You can
just keep on driving. The shorter the distance you
drive and the slower the speed, the greater the
chance that the tire will not have to be replaced. If
you drive on a deated run-at tire for 50 miles
(80 km) or less and at speeds of 55 mph (90 km/h)
or less, there is a good chance that the tire can
be repaired. The tire can operate effectively
with no air pressure for up to 100 miles (160 km)
at speeds up to 55 mph (90 km/h), but the tire
would then have to be replaced. When a tire
is lled with air, it provides a cushion between the
road and the wheel. Because you will not have
this cushion when driving on a deated tire, try to
avoid potholes that could damage your wheel
and require replacement of it.

When a low tire pressure condition is detected,
the TPMS illuminates the low tire pressure warning
light, located in the instrument panel cluster,
and at the same time the LOW TIRE PRESSURE
warning message on the Driver Information
Center (DIC) displays. The low tire pressure
warning light and the DIC warning message
appear at each ignition cycle until the tires are
inated to the correct ination pressure. For
additional information and details about the DIC
operation and displays seeDIC Controls and
Displays on page 204andDIC Warnings
and Messages on page 206.
You may notice, during cooler weather conditions,
that the low tire pressure warning light and the
LOW TIRE PRESSURE DIC warning message
may come on when the vehicle is rst started, and
then turn off as you start to drive. This may be
an early indicator that the air pressure in the tire(s)
is getting low and needs to be inated to the
proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires ofa different size than the size indicated on the
vehicle placard or tire ination pressure label, you
should determine the proper tire ination
pressure for those tires.)
As an added safety
feature, your vehicle
has been equipped with
a tire pressure
monitoring system
(TPMS) that illuminates
a low tire pressure
telltale when one
or more of your tires is
signicantly
under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and inate them to the
proper pressure. Driving on a signicantly
under-inated tire causes the tire to overheat and
can lead to tire failure. Under-ination also
reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.

Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use
spare tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.
While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform
to federal safety requirements and additional
General Motors Tire Performance Criteria (TPC)
standards.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specied
government test course. For example, a tire
graded 150 would wear one and a half (1.5) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from
the norm due to variations in driving habits, service
practices, and differences in road characteristics
and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the tire’s
ability to stop on wet pavement as measured
under controlled conditions on specied
government test surfaces of asphalt and concrete.
A tire marked C may have poor traction
performance.
Warning:The traction grade assigned to this tire
is based on straight-ahead braking traction
tests, and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
