The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
pressure, do not exceed the maximum in ation
pressure indicated on the tire’s sidewall.
You will have two minutes to match the rst
tire/wheel position, and ve minutes overall to
match all four tire/wheel positions. If it takes longer
than two minutes, to match the rst tire and
wheel, or more than ve minutes to match all four
tire and wheel positions the matching process
stops and you will need to start over.
The TPMS sensor matching process is outlined
below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Turn the headlamp control from off to parking
lamps four times within three seconds. A
double horn chirp will sound and the TPMS
low tire warning light will begin to ash.The double horn chirp and ashing TPMS
warning light indicate that the TPMS matching
process has started. The TPMS warning
light should continue ashing throughout the
matching procedure.
4. Start with the driver’s side front tire.
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, you will need to start over with step
number one. 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.

4. Press and release the switch to turn the air
in ator on. The indicator light will remain on
when the in ator is running.
The system has an internal clock to prevent
the system from overheating. The system
will allow about ve minutes of running time,
then the compressor will stop. The indicator
light will then begin to ash. When the indicator
is off, the in ator can be started again by
pressing the switch. If the compressor is still
hot, it may only run for a short time before
shutting off again.
5. Press and release the switch to turn the
in ator off.
Place the in ator kit tools in the pouch and store it
in its proper location. Remove the in ator hose
from the outlet during loading and unloading. Load
leveling will not function with the in ator hose
attached to the in ator outlet. SeeElectronically
Controlled Air Suspension System on page 337for
more information.
To reinstall the cover, line up the tabs at the back
of the cover, put it in place and latch the tabs.If the indicator light on the accessory in ator
ashes continuously, it could indicate that there is
a malfunction in the air suspension system.
SeeElectronically Controlled Air Suspension
System on page 337for more information.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. If air goes out of a tire, it is
much more likely to leak out slowly. But if you
should ever have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the at tire will create a drag
that pulls the vehicle toward that side. Take your
foot off the accelerator pedal and grip the
steering wheel rmly. Steer to maintain lane
position, and then gently brake to a stop well out
of the traffic lane.
