TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire, the
TPMS with Tire Inflation Indicator provides
visual and audible signals outside the vehicle
to help you inflate the tires to the recom-
mended COLD tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and press thepark button to engage the P (Park)
position.
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation:
1. Add air to the tire.
2. After a few seconds, the hazard indicators will start flashing.
3. When the designated pressure is reached, the horn beeps once and the hazard indi-
cators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more than ap-proximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three times. To correct the pressure,
push the core of the valve stem on the tire briefly to release pressure. When the
pressure reaches the designated pres-
sure, the horn beeps once.
• If the hazard indicator does not flash within approximately 15 seconds after
starting to inflate the tire, it indicates
that the TPMS with Tire Inflation Indi-
cator is not operating.
• The TPMS will not activate the TPMS with Tire Inflation Indicator under the
following conditions:– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation de- vice is not sufficient to inflate the tire.
– There is a malfunction in the TPMS.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
– The battery of the tire pressure sensor is low.
• If the TPMS with Tire Inflation Indicator does not operate due to TPMS interfer-
ence, move the vehicle about1m(3ft)
backward or forward and try again.
If the TPMS with Tire Inflation Indicator is
not working, use a tire pressure gauge.
ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than pas-
senger cars to make them capable of per-
forming in a variety of on-pavement and off-
road applications. This gives them a higher
center of gravity than ordinary vehicles. An
advantage of higher ground clearance is a
better view of the road, allowing you to an-
ticipate problems. However, they are not de-
signed for cornering at the same speeds as
conventional 2-Wheel Drive vehicles any
more than low-slung sports cars are de-
signed to perform satisfactorily under off-
road conditions. If at all possible, avoid sharp
turns at high speeds. As with other vehicles of
this type, failure to operate this vehicle cor-
rectly may result in loss of control or vehicle
rollover.
In a rollover crash, an unbelted person is sig-
nificantly more likely to die than a person
wearing a seat belt.
For additional information, see “Driving
safety precautions” (P. 5-10).
5-8Starting and driving

The BSW system uses radar sensorsO1in-
stalled near the rear bumper to detect other
vehicles in an adjacent lane. The radar sensors can detect vehicles on ei-
ther side of your vehicle within the detection
zone shown as illustrated. This detection
zone starts from the outside mirror of your
vehicle and extends approximately 10 ft (3.0
m) behind the rear bumper, and approxi-
mately 10 ft (3.0 m) sideways.

BSW SYSTEM OPERATION
The BSW system operates above approxi-
mately 20 mph (32 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light
O1
illuminates. If the turn signal is then activated,
the system chimes (twice) and the side indi-
cator light flashes. The side indicator light
continues to flash until the detected vehicle
leaves the detection zone.
The side indicator light illuminates for a few
seconds when the ignition switch is placed in
the ON position.
If a vehicle comes into the detection zone
after the driver activates the turn signal, then
only the side indicator light flashes and no
chime sounds. For additional information, see
“BSW driving situations” (P. 5-48).

BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the BSW system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.
• The BSW system cannot detect all ve-
hicles under all conditions.
• The radar sensors may not be able to de-
tect and activate BSW when certain ob-
jects are present such as:
– Pedestrian, bicycles, animals.
– Vehicles such as motorcycles, low
height vehicles, or high ground clear-
ance vehicles.
– Oncoming vehicles.
– Vehicles remaining in the detection
zone when you accelerate from a
stop.
– A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle.
– A vehicle approaching rapidly from
behind.
– A vehicle which your vehicle over-
takes rapidly. –
A vehicle that passes through the de-
tection zone quickly.
– When overtaking several vehicles in a
row, the vehicles after the first ve-
hicle may not be detected if they are
traveling close together.
• The radar sensors’ detection zone is de-
signed based on a standard lane width.
When driving in a wider lane, the radar
sensors may not detect vehicles in an ad-
jacent lane. When driving in a narrow
lane, the radar sensors may detect ve-
hicles driving two lanes away.
• The radar sensors are designed to ignore
most stationary objects; however, ob-
jects such as guardrails, walls, foliage
and parked vehicles may occasionally be
detected. This is a normal operation
condition.
• The following conditions may reduce the
ability of the radar to detect other ve-
hicles:
– Severe weather
– Road spray
– Ice/frost/snow/dirt build-up on the
vehicle •
Do not attach stickers (including trans-
parent material), install accessories or
apply additional paint near the radar
sensors. These conditions may reduce
the ability of the radar to detect other
vehicles.
• Excessive noise (for example, audio sys-
tem volume, open vehicle window) will
interfere with the chime sound, and it
may not be heard.

Failure to follow the warnings and instruc-
tions for proper use of the BSI system could
result in serious injury or death.
• The BSI system is not a replacement for
proper driving procedure and is not de-
signed to prevent contact with vehicles
or objects. When changing lanes, always
use the side and rear mirrors and turn
and look in the direction you will move to
ensure it is safe to change lanes. Never
rely solely on the BSI system.
• There is a limitation to the detection ca-
pability of the radar or the sonar. Not
every moving object or vehicle will be de-
tected. Using the BSI system under some
road, ground, lane marker, traffic or
weather conditions could lead to im-
proper system operation. Always rely on
your own operation to avoid accidents.
The BSI system helps alert the driver of other
vehicles in adjacent lanes when changing
lanes and helps assist the driver to return the
vehicle to the center of the traveling lane. The BSI system uses radar sensors
O2in-
stalled near the rear bumper to detect other
vehicles in an adjacent lane. In addition to the
radar sensors, the BSI system uses a camera
O1installed behind the windshield to monitor
the lane markers of your traveling lane.
The radar sensors can detect vehicles on ei-
ther side of your vehicle within the detection
zone shown as illustrated. This detection
zone starts from the outside mirror of your
vehicle and extends approximately 10 ft (3.0
m) sideways.

BLIND SPOT INTERVENTION® (BSI)
5-52Starting and driving

The BSI system operates above approxi-
mately 37 mph (60 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light (1)
illuminates.
If the turn signal is then activated, the system
chimes (twice) and the side indicator light
flashes. The side indicator light continues to
flash until the detected vehicle leaves the
detection zone.
If the BSI system is on and your vehicle ap-
proaches a lane marker while another vehicle
is in the detection zone, the system chimes
(three times) and the side indicator light
flashes. The BSI system activates to help re-
turn the vehicle back to the center of the
driving lane. The BSI system operates regard-
less of turn signal usage.
NOTE:
• BSI warning and system application willonly be activated if the side indicator light
is already illuminated when your vehicle
approaches a lane marker. If another ve-
hicle comes into the detection zone after
your vehicle has crossed a lane marker, no
BSI warning or system application will be
activated. For additional information, see
“BSI driving situations” (P. 5-57 ). • The BSI system is typically activated ear-
lier than the Lane Departure Prevention
(LDP) system when your vehicle is ap-
proaching a lane marker.
The BSI system turns on when the ProPILOT
Assist switch on the steering wheel is pushed
when the “Blind Spot Intervention” is enabled
in the “Driver Assistance” menu in the lower
display. The BSI ON indicator on the instru-
ment panel illuminates when the BSI system
is turned on.
The BSI system provides a chime and turns on
or flashes the side indicator light even if the
BSW system is off.
