correct tire pressure using an accurate tire gauge,
even if under-inflation has not reached the level to
trigger illumination of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pres-
sure, and the TPMS will monitor the actual tire
pressure in the tire.
Base System
This is the TPMS warning indicator located in
the instrument cluster.
The TPMS uses wireless technology with
wheel rim mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each wheel as part
of the valve stem, transmit tire pressure readings to the
Receiver Module.
NOTE: It is particularly important for you to check the
tire pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure. The TPMS consists of the following components:
•
Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring System Warning Light.
Tire Pressure Monitoring Low Pressure Warnings
The TPMS Warning Light will illuminate in the instru-
ment cluster, an acoustic signal will be activated, and
the “Check left or right front/rear tire” text message
will display when one or more of the four active road
tire pressures are low. Should this occur, you should
stop as soon as possible, check the inflation pressure of
each tire on your vehicle, and inflate each tire to the
vehicle’s recommended cold placard pressure value.
The system will automatically update and the Tire
Pressure Monitoring Light will extinguish once the
updated tire pressures have been received. The vehicle
may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.
96 SAFETY

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.

SAFETY 133

•The variation in sensor position, caused by variation
in ride (due to suspension component wear), chang-
ing tires, overloaded vehicle, or tuning that lowers
the vehicle, for example, may affect parking sensor
system performance.
NOTE: The sensor must be free from mud, dirt snow or
ice in order for the system to operate correctly. Be
careful not to scratch or damage the sensors while
cleaning them. Avoid using dry, rough or hard cloths.
The sensors must be washed using clean water, with the
addition of car shampoo if necessary. When using
special washing equipment such as high pressure jets or
steam cleaning, clean the sensors very quickly keeping
the jet more than 4 inches (10 cm) away. Also, do not
apply stickers to the sensors.
WARNING!
Drivers must be careful when backing up even
when using the Parking Sensor system. Always
check carefully behind your vehicle, and be sure to
check for pedestrians, animals, other vehicles, ob-
structions, or blind spots before backing up. You
are responsible for the safety of your surroundings
(Continued)
WARNING! (Continued)
and must continue to pay attention while backing
up. Failure to do so can result in serious injury or
death.
CAUTION!
•The Parking Sensor system is only a parking aid
and it is unable to recognize every obstacle,
including small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will
not be detected when they are in close proximity.
• The vehicle must be driven slowly when using
the Parking Sensor system in order to be able to
stop in time when an obstacle is detected. It is
recommended that the driver looks over his/her
shoulder when using the Parking Sensor system.
PARKVIEW REAR BACK UP CAMERA
The ParkView Rear Back Up Camera allows you to see
an on-screen image of your vehicle’s rear surroundings
when the gear selector is put into REVERSE. The image
will be displayed on the rearview mirror along with a

DRIVING TIPS
Driving On Slippery Surfaces
Information in this section will aid in safe controlled
launches in adverse conditions.
Acceleration
Rapid acceleration on snow covered, wet, or other
slippery surfaces may cause the driving wheels to pull
erratically to the right or left. This phenomenon occurs
when there is a difference in the surface traction under
the rear (driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is danger-
ous. Unequal traction can cause sudden pulling of
the rear wheels. You could lose control of the
vehicle and possibly have a collision. Accelerate
slowly and carefully whenever there is likely to be
poor traction (ice, snow, wet, mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for
a wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may causepartial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
•
Slow down during rainstorms or when the roads are
slushy.
• Slow down if the road has standing water or
puddles.
• Replace tires when tread wear indicators first become
visible.
• Keep tires properly inflated.
• Maintain sufficient distance between your vehicle
and the vehicle in front of you to avoid a collision in
a sudden stop.
Your vehicle may be equipped with a Limited Slip
Differential (LSD) that reduces, but does not eliminate,
the amount of wheel slip across a given axle for
improved handling.
Driving Through Water
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.

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 Identification Number (TIN)
The TIN may be found on one or both sides of the tire;
however, the date code may only be on one side. Tires
with white sidewalls will have the full TIN, including
the date code, located on the white sidewall side of thetire. Look for the TIN on the outboard side of black
sidewall tires as mounted on the vehicle. If the TIN is
not found on the outboard side, then you will find it on
the inboard side of the tire.
EXAMPLE:
DOT MA L9 ABCD 0301
DOT = Department of Transportation
–This symbol certifies that the tire is in compliance with the U.S. Department of Transportation tire safety
standards and is approved for highway use
MA = Code representing the tire manufacturing location (two digits)
L9 = Code representing the tire size (two digits)
ABCD = Code used by the tire manufacturer (one to four digits)
03 = Number representing the week in which the tire was manufactured (two digits)
–03 means the 3rd week
01 = Number representing the year in which the tire was manufactured (two digits)
–01 means the year 2001
–Prior to July 2000, tire manufacturers were only required to have one number to represent the year in which
the tire was manufactured. Example: 031 could represent the 3rd week of 1981 or 1991
