112SAFETY
If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the TPMS
Warning Light will no longer flash, and the
"Service Tire Pressure System" message will no
longer display, and a pressure value will display
in place of the dashes. A system fault can occur
due to any of the following:
Signal interference due to electronic devices
or driving next to facilities emitting the same
radio frequencies as the TPM sensors.
Accumulation of snow or ice around the
wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPM
sensors.
Vehicles With Compact Spare
1. The compact spare tire or non-matching full size does not have a Tire Pressure
Monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the
compact spare tire.
2. If you install the compact or non-matching full size spare tire in place of a road tire that
has a pressure below the low-pressure warning limit, upon the next ignition key
cycle, the TPMS Warning Light will remain
on and a chime will sound. In addition, the
graphic in the instrument cluster will still
display a different color pressure value and
an "Inflate to XX" message.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPMS Warning
Light will flash on and off for 75 seconds and
then remain on solid. In addition, the
instrument cluster will display a “Service Tire
Pressure System” message for five seconds
and then display dashes (- -) in place of the
pressure value.
4. For each subsequent ignition key cycle, a chime will sound, the TPMS Warning Light
will flash on and off for 75 seconds and then
remain on solid, and the instrument cluster
will display a “Service Tire Pressure System”
message for five seconds and then display
dashes (- -) in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of
the compact spare or non-matching full
size, the TPMS will update automatically.
In addition, the TPMS Warning Light will turn off and the graphic in the instrument cluster
will display a new pressure value instead of
dashes (- -), as long as no tire pressure is
below the low-pressure warning limit in any
of the four active road tires. The vehicle may
need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the
TPMS to receive this information.
TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS)
can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and
tire assemblies that do not have TPMS Sensors,
such as when installing winter wheel and tire
assemblies on your vehicle.
To deactivate the TPMS, first replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
(TPM) sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS Warning Light will
flash on and off for 75 seconds and then remain
on. The instrument cluster will display the
“Service Tire Pressure System” message and
then display dashes (--) in place of the pressure
values.

TIRE CHAINS AND TRACTION DEVICES
Use of traction devices require sufficient
tire-to-body clearance. Due to limited clearance,
the following traction devices are
recommended. Follow these recommendations
to guard against damage.
Traction device must be of proper size for the
tire, as recommended by the traction device
manufacturer.
No other tire sizes are recommended for use
with a tire chain or traction device.
Install on rear tires only.
Rear Wheel Drive (RWD) Models : For a P215/
65R17 and P225/60R18 use of Peerless
Chain Super Z6 low profile traction device or
equivalent is recommended.
All Wheel Drive (AWD) Models : For a P235/
55R19 tire, use of an S Class traction device
or equivalent is recommended.
CAUTION!
If your vehicle is equipped with these
specialty wheels, DO NOT USE wheel
cleaners, abrasives, or polishing compounds.
They will permanently damage this finish and
such damage is not covered by the New
Vehicle Limited Warranty. HAND WASH ONLY
USING MILD SOAP AND WATER WITH A SOFT
CLOTH. Used on a regular basis; this is all that
is required to maintain this finish.
WARNING!
Using tires of different size and type (M+S,
Snow) between front and rear axles can
cause unpredictable handling. You could lose
control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
Because of restricted traction device clear -
ance between tires and other suspension
components, it is important that only trac-
tion devices in good condition are used.
Broken devices can cause serious damage.
Stop the vehicle immediately if noise
occurs that could indicate device breakage.
Remove the damaged parts of the device
before further use.
Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km). Autosock traction devices do not
require retightening.
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns and
large bumps, especially with a loaded
vehicle.
Do not drive for a prolonged period on dry
pavement.
Observe the traction device manufacturer’s
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed
of the device manufacturer’s if it is less
than 30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
CAUTION! (Continued)
