— Low Washer Fluid Warning Light — If Equipped
This warning light will illuminate when the windshield
washer fluid is low.
— Low Fuel Warning Light
When the fuel level reaches approximately 3.2 gal (12 L) this
light will turn on, and remain on until fuel is added.
A single warning chime will sound with Low Fuel Warning.
— Low Coolant Level Warning Light
This telltale will turn on to indicate the vehicle coolant level
is low.
— Loose Fuel Filler Cap Warning Light — If Equipped
This warning light will illuminate when the fuel filler cap is
loose. Properly close the filler cap to disengage the light. If
the light does not turn off, please see an authorized dealer. — Tire Pressure Monitoring System (TPMS) Warning
Light
The warning light switches on and a message is displayed to
indicate that the tire pressure is lower than the recom -
mended value and/or that slow pressure loss is occurring. In
these cases, optimal tire duration and fuel consumption may
not be guaranteed.
Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire.

Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the vehicle placard
or tire inflation pressure label, you should determine the
proper tire inflation pressure for those tires.)

CAUTION!

Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle, avoiding
sharp braking and steering. If a tire puncture occurs, repair
immediately using the dedicated tire repair kit and contact
an authorized dealer as soon as possible.

GETTING TO KNOW YOUR INSTRUMENT PANEL 153
As an added safety feature, your vehicle has been equipped
with a Tire Pressure Monitoring System (TPMS) that illumi-
nates a low tire pressure telltale when one or more of your
tires is significantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain
correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pres -
sure telltale.
Your vehicle has also been equipped with a TPMS malfunc -
tion indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approximately one
minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi -
cator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation
of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly. Always check
the TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replace
-
ment or alternate tires and wheels allow the TPMS to
continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size equipped
on your vehicle. Undesirable system operation or sensor
damage may result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to your
authorized dealer to have your sensor function checked.

SAFETY 177
General Information
The following regulatory statement applies to all Radio
Frequency (RF) devices equipped in this vehicle:
This device complies with Part 15 of the FCC Rules and with
Industry Canada license-exempt RSS standard(s). Operation
is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received,including interference that may cause undesired opera -
tion.
NOTE:
Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s
authority to operate the equipment.
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom -
mended cold placard pressure.
NOTE:
The TPMS Warning Light will illuminate in the instrument
cluster and a chime will sound when tire pressure is low in one or more of the four active road tires. In addition, the
instrument cluster will display a graphic showing the pres
-
sure values of each tire with the low tire pressure values in a
different color, or the Uconnect radio will display a TPMS
message, when this occurs you must increase the tire pres -
sure to the recommended cold placard pressure in order for
the TPMS Warning Light to turn off.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after the vehicle has not been driven for at least three hours,
or driven less than 1 mile (1.6 km) after a three hour period.
The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire sidewall.
Refer to “Tires” in “Servicing And Maintenance” for infor -
mation on how to properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is driven - this is
normal and there should be no adjustment for this increased
pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.

178 SAFETY
The TPMS will continue to warn the driver of low tire pres-
sure as long as the condition exists, and will not turn off until
the tire pressure is at or above the recommended cold
placard pressure. Once the low TPMS Warning Light illumi -
nates, you must increase the tire pressure to the recom -
mended cold placard pressure in order for the TPMS
Warning Light to turn off. The system will automatically
update and the TPMS Warning Light will turn off once the
system receives the updated tire pressures. 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.
NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the recom -
mended cold placard pressure in order to turn the TPMS
Warning Light off.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of 30 psi
(207 kPa). If the ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a temperature
drop to 20°F (-7°C) will decrease the tire pressure to approx -
imately 23 psi (158 kPa). This tire pressure is sufficiently low
enough to turn on the TPMS Warning Light. Driving the
vehicle may cause the tire pressure to rise to approximately
27 psi (186 kPa), but the TPMS Warning Light will still be on. In this situation, the TPMS Warning Light will turn off only
after the tires are inflated to the vehicle’s recommended cold
placard pressure value.
CAUTION!
• The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equipment
that is not of the same size, type, and/or style. After -
market wheels can cause sensor damage.
• Using aftermarket tire sealants may cause the Tire Pres -
sure Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho -
rized dealership to have your sensor function checked.
• After inspecting or adjusting the tire pressure always reinstall the valve stem cap. This will prevent moisture
and dirt from entering the valve stem, which could
damage the TPMS sensor.
