on page 437for more information.
Replacement blades come in different types and
are removed in different ways. For proper type and
length, seeNormal Maintenance Replacement
Parts on page 449.
Allowing the wiper blade arm to touch the
windshield when no wiper blade is installed could
damage the windshield. Any damage that
occurs would not be covered by your warranty. Do
not allow the wiper blade arm to touch the
windshield.

5. Remove the valve cap from the valve cap
stem. Activate the TPMS sensor by
increasing or decreasing the tire’s air pressure
for 10 seconds, then stop and listen for a
single horn chirp. The single horn chirp should
sound within 15 seconds, con rming that
the sensor identi cation code has been
matched to this tire and wheel position. If you
do not hear the con rming single horn
chirp, turn the ignition switch to LOCK and
start over beginning with Step 2. To let
air-pressure out of a tire you can use the
pointed end of the valve cap, a pencil-style air
pressure gage, or a key.
6. Proceed to the passenger’s side front tire, and
repeat the procedure in Step 5.
7. Proceed to the passenger’s side rear tire, and
repeat the procedure in Step 5.8. Proceed to the driver’s side rear tire, and
repeat the procedure in Step 5.
9. After hearing the con rming horn chirp for the
driver side rear tire, check to see if the TPMS
low tire warning light and the DIC LOW
TIRE messages have turned off. If yes, the
TPMS sensors have been relearned. Turn the
ignition switch to LOCK.
If the low tire warning light and the DIC SERV
TPM messages are on after completing
Step 5 for the driver side rear tire, the sensor
relearn process has not been successful.
Turn the ignition switch to LOCK and repeat
the matching process beginning with Step 2.
10. Set all four tires to the recommended
air pressure level as indicated on the Tire and
Loading Information label.
11. Put the valve caps back on the valve stems.

Different Size Tires and Wheels
If you add wheels or tires that are a different size
than your original equipment wheels and tires,
this may affect the way your vehicle performs,
including its braking, ride and handling
characteristics, stability, and resistance to rollover.
Additionally, if your vehicle has electronic
systems such as, anti-lock brakes, traction control,
and electronic stability control, the performance
of these systems can be affected.{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires not
recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use GM speci c wheel and
tire systems developed for your vehicle,
and have them properly installed by a GM
certi ed technician.
SeeBuying New Tires on page 386and
Accessories and Modi cations on page 316for
additional information.
