SAFETY FEATURES
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking condi-
tions. The system operates with a separate computer to
modulate hydraulic pressure, to prevent wheel lock-up
and to help avoid skidding on slippery surfaces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When the
light is illuminated, the ABS is not functioning. The system
reverts to standard non-anti-lock brakes. Turning the igni-
tion OFF and ON again may reset the ABS if the fault
detected was only momentary.
WARNING!
•The ABS contains sophisticated electronic equip-
ment that may be susceptible to interference caused
(Continued)
WARNING! (Continued)
by improperly installed or high output radio trans-
mitting equipment. This interference can cause pos-
sible loss of anti-lock braking capability. Installation
of such equipment should be performed by qualified
professionals.
• Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
• The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase brak-
ing or steering efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the
traction afforded.
• The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
• The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user ’s safety or the safety of
others.
100 SAFETY

The RBS uses conventional hydraulic friction brakes, re-
generative braking, or a combination to slow the vehicle. If
the system detects slippery conditions while braking,
ONLY friction is used to slow the vehicle. The RBS can
result in extended life of the hydraulic service brakes;
however, all inspection, scheduled maintenance, and ser-
vice intervals for the vehicle service brakes must be fol-
lowed.
AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
The tire pressure will vary with temperature by about 1psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will de-
crease. 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 – General Information” in “Servicing AndMaintenance” for information 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.
The TPMS will continue to warn the driver of low tire
pressure 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 tire pressure warning
(Tire Pressure Monitoring System Warning Light) illumi-
nates, you must increase the tire pressure to the recom-
mended cold placard pressure in order for the Tire Pressure
Monitoring System Warning Light to turn off. The system
will automatically update and the Tire Pressure Monitoring
System Warning Light will turn off once the system re-
ceives 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.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of
33 psi (227 kPa). If the ambient temperature is 68°F (20°C)
5
SAFETY 105

and the measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is low enough to turn ON the “Tire Pressure
Monitoring System Warning Light.” Driving the vehicle
may cause the tire pressure to rise to approximately 28 psi
(193 kPa), but the Tire Pressure Monitoring System Warn-
ing Light will still be on. In this situation, the Tire Pressure
Monitoring System 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
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. The TPM sensor is not designed
for use on aftermarket wheels and may contribute to
a poor overall system performance or sensor damage.
(Continued)
CAUTION! (Continued)
Customers are encouraged to use OEM wheels to
assure proper TPM feature operation.
• Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealership to have your sensor
function checked.
• After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
106 SAFETY

•Under-inflation also reduces the high voltage battery
range and tire tread life, and may affect the vehicle’s
handling and stopping ability.
• It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and
to maintain the proper pressure.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the level
to trigger illumination of the Tire Pressure Monitoring
System Warning Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
TPM System
The Tire Pressure Monitor System (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. The TPMS consists of the following components:
•
Receiver module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
• Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring System 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 low pressure graphic showing the
low tire pressure tire highlighted in a different color.
5
SAFETY 107

Should this occur, you should stop as soon as possible and
inflate the tires with low pressure to the vehicle’s recom-
mended cold placard pressure value. Once the system
receives the updated tire pressures, the system will auto-
matically update and the Tire Pressure Monitoring System
Warning Light will turn off. 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 Warning
When a system fault is detected, the Tire Pressure Moni-
toring System Warning Light will flash on and off for 75
seconds and then remain on solid. The system fault will
sound a chime and also display a “Service Tire Pressure
Monitoring System” message in the instrument cluster for
approximately five seconds.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the Tire Pressure Monitoring System Warning
Light will no longer flash, and the “Service TPM System”
message will no longer display.
Low Tire Indicator
Service TPM System Message
108 SAFETY

A system fault can occur due to any of the following:
1. Signal interference due to electronic devices or drivingnext to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains ma- terials that may block radio wave signals.
3. Accumulation of 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:
• The TPMS will not monitor the pressure in a replace-
ment tire installed without a tire pressure sensor.
• If you install a replacement tire in place of a road tire
that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the Tire
Pressure Monitoring System Warning Light will remain
on and a chime will sound. In addition, the highlighted
graphic in the instrument cluster will still display a low
pressure text message and a pressure value in a different
color. •
After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring System
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 Monitoring System”
message.
• For each subsequent ignition switch cycle, a chime will
sound, the Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds and then
remain on solid, and the instrument cluster will display
a “Service TPM System” message.
Once you repair or replace the original road tire and
reinstall it, the TPMS will update automatically. In addi-
tion, the Tire Pressure Monitoring System 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 need to be driven for up to 20
minutes above 15 mph (24 km/h) in order for the TPMS to
receive this information.

SAFETY 109

WARNING!(Continued)
•ALWAYS make sure objects cannot fall or slide into
the driver ’s side floor area when the vehicle is
moving. Objects can become trapped under accelera-
tor, brake, or clutch pedals and could cause a loss of
vehicle control.
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the
position of the floor mat and may cause interference
with the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
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 (includ-
ing spare) for proper cold inflation pressure.
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 vehicle after overnight parking for
coolant or other fluid leaks. If fluid leaks are suspected, the
cause should be located and corrected immediately.

SAFETY 151

The sensors and wiring are tested continuously when the
ignition is in the ON/RUN position. Failures are indicated
immediately if they occur when the system is on.
Even if the system is able to identify that a specific sensor
is in failure condition, the instrument cluster display shall
indicate that the Rear Park Assist system is unavailable,
without reference to the sensor in failure condition. If even
a single sensor fails, the entire system must be disabled.
The system is turned off automatically.
Cleaning The Rear Park Assist System
Clean the Rear Park Assist sensors with water, car wash
soap and a soft cloth. Do not use rough or hard cloths. In
washing stations, clean sensors quickly keeping the vapor
jet/high pressure washing nozzles at least 4 inches (10 cm)
from the sensors. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
Park Assist System Usage Precautions
NOTE:
•Ensure that the outer surface and the underside of the
rear bumper is clean and clear of snow, ice, mud, dirt or
other obstruction to keep the Rear Park Assist system
operating properly. •
Jackhammers, large trucks, and other vibrations could
affect the performance of Rear Park Assist.
• Clean the Rear Park Assist sensors regularly, taking care
not to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The Rear Park Assist system might not detect
an obstacle behind the fascia/bumper, or it could pro-
vide a false indication that an obstacle is behind the
fascia/bumper.
• Objects such as bicycle carriers, etc., must not be placed
within 12 inches (30 cm) from the rear fascia/bumper
while driving the vehicle. Failure to do so can result in
the system misinterpreting a close object as a sensor
problem, causing a failure indication to be displayed in
the instrument cluster display.
WARNING!
•Drivers must be careful when backing up even when
using ParkSense. Always check carefully behind
your vehicle, look behind you, and be sure to check
for pedestrians, animals, other vehicles, obstructions,
