normal, turn the engine off immediately and call for
service.
Refer to “If Your Engine Overheats” in “In Case Of
Emergency” for further information.
Yellow Warning Lights
— Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is dis-
played to indicate that the tire pressure is lower than
the recommended 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 corre-
sponding to each tire.
CAUTION!
Do not continue driving with one or more flat tires
as handling may be compromised. Stop the vehicle,
(Continued)
CAUTION! (Continued)
avoiding sharp braking and steering. If a tire punc-
ture occurs, repair immediately using the dedicated
tire repair kit and contact an authorized dealer as
soon as possible.
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 pres-
sure label, you should determine the proper tire infla-
tion 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 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 pres-
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure.
78 GETTING TO KNOW YOUR INSTRUMENT PANEL

Check TPMS Warnings
The TPMS Warning Light will flash on and off for 75
seconds and remain on solid when a system fault is
detected, the “TIRE PRESSURE MONITORING UN-
AVAILABLE” text message will display. If the ignition
key is cycled, this sequence will repeat providing the
system fault still exists. The TPMS Warning Light will
turn off when the fault condition no longer exists. A
system fault can occur with any of the following
scenarios:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE: Your vehicle may be equipped with a compact
spare wheel and tire assembly. 1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not
monitor the tire pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure
warning limit, upon the next ignition key cycle, a
chime will sound and the TPMS Warning Light will
still turn ON due to the low tire.
3. However, after driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPMS Warn-
ing Light will flash on and off for 75 seconds and
then remain on solid.
4. This occurs for each subsequent ignition key cycle, a chime will sound and the TPMS Warning Light will
flash on and off for 75 seconds and then remain on
solid.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact
spare tire, the TPMS will update automatically and
the TPMS Warning Light will turn OFF, as long as no
tire pressure is below the low-pressure warning limit
in any of the four active road tires. The vehicle may

SAFETY 97

Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for
cuts and cracks. Inspect sidewalls for cuts, cracks, and
bulges. Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation pres-
sure.
Lights
Have someone observe the operation of brake lights
and exterior lights while you work the controls. Check
turn signal and high beam indicator lights on the
instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking
for fuel, coolant, oil, or other fluid leaks. Also, if
gasoline fumes are detected or if fuel, or brake fluid
leaks are suspected. The cause should be located and
corrected immediately.

Tire Safety Information
Tire safety information will cover aspects of the follow-
ing information: Tire Markings, Tire Identification
Numbers, Tire Terminology and Definitions, Tire Pres-
sures, and Tire Loading.
Tire Markings
NOTE:
•P (Passenger) — Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
• European — Metric tire sizing is based on European
design standards. Tires designed to this standard
have the tire size molded into the sidewall beginning
with the section width. The letter Pis absent from
this tire size designation. Example: 215/65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
• Temporary spare tires are designed for temporary
emergency use only. Temporary high pressure com-
pact spare tires have the letter “T” or “S” molded into
the sidewall preceding the size designation. Ex-
ample: T145/80D18 103M.
• High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter
molded into the sidewall. Example: 31x10.5 R15 LT.

Tire Loading And Tire Pressure
NOTE:The proper cold tire inflation pressure is listed
on the driver ’s side B-Pillar or the rear edge of the
driver’s side door.
Check the inflation pressure of each tire, including the
spare tire (if equipped), at least monthly and inflate to
the recommended pressure for your vehicle.

Tire And Loading Information Placard
This placard tells you important information about the:
1. Number of people that can be carried in the vehicle.
2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear, andspare tires.Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle.
You will not exceed the tire’s load carrying capacity if
you adhere to the loading conditions, tire size, and cold
tire inflation pressures specified on the Tire and Load-
ing Information placard in “Vehicle Loading” in the
“Starting And Operating” section of this manual.
NOTE: Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front and
rear axles must not be exceeded.
For further information on GAWRs, vehicle loading,
and trailer towing, refer to “Vehicle Loading” in the
“Starting And Operating” section of this manual.
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX kg or
XXX lbs” on the Tire and Loading Information placard.
The combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never ex-
ceed the weight referenced here.
