or death.WARNING
In case of a collision:
.If your vehicle is drivable, pull your
vehicle off the road, put the trans-
mission in the P (Park) position, apply
the parking brake and turn the
INFINITI Direct Response Hybrid
®
System off.
. Check to see if there are exposed high
voltage parts and cables. Never touch
the parts and cables. For their loca-
tions, see “High voltage components”
(P.Hybrid System-9). To avoid per-
sonal injury, never touch high-vol-
tage wiring, connectors, and other
high-voltage parts, such as electric
motor inverter and Lithium ion (Li-
ion) battery. An electric shock may
occur if exposed electric wires are
visible when viewed from inside or
outside of your vehicle. Therefore,
never touch exposed electric wires.
. If the vehicle receives a strong impact
to the floor while driving, stop the
vehicle in a safe location and check
the floor.
. Inspect the ground under the vehicle.
If liquid has leaked onto the ground,
the fuel system may have been da- maged. Leave the vehicle as soon as
possible.
. Leaks or damage to the Li-ion bat-
tery may result in a fire. If you
discover them, contact emergency
services immediately. Since the fluid
leak may be lithium organic electro-
lyte from the Li-ion battery, never
touch the fluid leak inside or outside
the vehicle. If the fluid contacts your
skin or eyes, wash it off immediately
with a large amount of water and
receive immediate medical attention
to help avoid serious injury.
. If a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possible.
Only use a type ABC, BC or C fire
extinguisher that is meant for use on
electrical fires. Using water or the
incorrect fire extinguisher can result
in serious injury or death from elec-
trical shock.
. If you are not able to safely assess
the vehicle due to vehicle damage, do
not touch the vehicle. Leave the
vehicle and contact emergency ser-
vices. Advise 1st responders that this
is a hybrid vehicle.
. In the event of an accident that
requires body repair and painting, it
is recommended that the vehicle be

fluid reservoir, do not drive until the
brake system has been checked. It is
recommended you visit an INFINITI
retailer for this service.
Direct Response Hybrid®Sys-
tem warning light
When the ignition switch is in the ON
position, the Direct Response Hybrid®Sys-
tem (hybrid system) warning light illumi-
nates. After starting the hybrid system, the
hybrid system warning light turns off.
If the hybrid system warning light illuminates
while driving, it may indicate that there is a
malfunction in the electric motor and/or
other hybrid system components.
Stop your vehicle immediately and it is
recommended that you contact your
INFINITI retailer.
If the hybrid system warning light blinks
while driving, it may indicate that the Li-ion
battery charge is low and you cannot
continue to drive.

after the 1 minute. Have the system checked.
It is recommended you visit an INFINITI
retailer for this service. THE CHECK TIRE
PRESSURE warning does not appear if the
low tire pressure warning light illuminates to
indicate a TPMS malfunction.
For additional information, see “Tire Pres-
sure Monitoring System (TPMS) ” (P.5-5).
WARNING
.If the light does not illuminate with
the ignition switch pushed ON, have
the vehicle checked. It is recom-
mended you visit an INFINITI retailer
for this service as soon as possible.
. If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location
and stop the vehicle as soon as
possible. Driving with under-inflated
tires may permanently damage the
tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an
accident and could result in serious
personal injury. Check the tire pres-
sure for all four tires. Adjust the tire
pressure to the recommended COLD
tire pressure shown on the Tire and Loading Information label to turn the
low tire pressure warning light OFF.
If the light still illuminates while
driving after adjusting the tire pres-
sure, a tire may be flat or the TPMS
may be malfunctioning. If you have a
flat tire, replace it with a spare tire as
soon as possible. If no tire is flat and
all tires are properly inflated, have
the vehicle checked. It is recom-
mended you visit an INFINITI retailer
for this service.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on after the 1 minute.
Have your tires replaced and/or
TPMS system reset as soon as pos-
sible. It is recommended you visit an
INFINITI retailer for these services.
. Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.
CAUTION
.The TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly.
. If the vehicle is being driven at speeds
of less than 16 MPH (25 km/h), the
TPMS may not operate correctly.
. Be sure to install the specified size of
tires to the four wheels correctly.

BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a regenerative brake booster even with
light pedal force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that
stopping distances on slippery sur- faces will be longer than on normal
surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered roads,
or if you are using tire chains. Always
maintain a safe distance from the
vehicle in front of you. Ultimately,
the driver is responsible for safety.
. Tire type and condition may also
affect braking effectiveness.
— When replacing tires, install the specified size of tires on all four
wheels.
— When installing a spare tire, make sure that it is the proper size and
type as specified on the Tire and
Loading Information label. See
“Tire and loading information la-
bel” (P.10-10).
— For detailed information, see “Wheels and tires” (P.8-26).
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during
hard braking or when braking on slippery
surfaces. The system detects the rotation
speed at each wheel and varies the brake
fluid pressure to prevent each wheel from
locking and sliding. By preventing each
wheel from locking, the system helps the driver maintain steering control and helps to
minimize swerving and spinning on slippery
surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid
obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic
feature that tests the system each time you
start the hybrid system and move the vehicle
at a low speed in forward or reverse. When
the self-test occurs, you may hear a “clunk”
noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a mal-
function, it switches the ABS off and
