parking brake INFINITI Q50-HYBRID 2014 Owners Manual

WARNING
In case of a collision:
.If your vehicle is drivable, pull your
vehicle off the road, put the transmis-
sion 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 locations,
see “High voltage components” (P.Hy-
brid System-9). To avoid personal injury,
never touch high-voltage wiring, con-
nectors, 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. There-
fore, 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 damaged. Leave the vehicle as soon as possible.
. Leaks or damage to the Li-ion battery
may result in a fire. If you discover them,
contact emergency services immedi-
ately. Since the fluid leak may be lithium
organic electrolyte from the Li-ion bat-
tery, never touch the fluid leak inside or
outside the vehicle. If the fluid contacts
your skin or eyes, wash it off immedi-
ately 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 electrical
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 services. Advise 1st
responders that this is a hybrid vehicle.
. In the event of an accident that requires
body repair and painting, the vehicle
should be delivered to an INFINITI retailer to have the Li-ion battery pack
and high voltage parts such as the
inverter, including the wiring harness,
removed prior to painting. Li-ion battery
packs exposed to heat in the paint booth
will experience capacity loss. Damaged
Li-ion battery packs may also pose
safety risks to untrained mechanics
and repair personnel.
Hybrid System OverviewHybrid System-3
ROAD ACCIDENT CAUTIONS

Hybrid System-8Hybrid System Overview
When the vehicle decelerates while the
vehicle is driven with the shift lever in the
D (Drive) position or in the manual shift
mode, the Lithium ion (Li-ion) battery can
be charged by the electric motor. The
electric motor converts the energy of the
rotating wheels into electric power under
the following circumstances:
.When the accelerator pedal is released.
. When the brake pedal is depressed.
. When there is no malfunction in the
brake system or the INFINITI Direct
Response Hybrid
®System.
The regenerative brake may not work
properly if the vehicle has tires and road
wheels other than the ones specified in
this manual. Drive your vehicle with smooth accelera-
tion and deceleration.
.
While driving, energy is recovered
through the regenerative brake as the
vehicle decelerates. However, for most
efficient use, do not accelerate or
decelerate your vehicle more than
necessary.
. Avoid abrupt acceleration and decelera-
tion.
. The power of the Lithium ion (Li-ion)
battery can be checked on the Energy
Flow or Energy monitor. See “Energy
Flow” (P.Hybrid System-5) or “Trip
computer” (P.2-31). Gradual or non-
abrupt acceleration and deceleration
will make more effective use of the
electric using gasoline engine power.
. When parking, be sure to place the shift
lever in the P (Park) position. While
driving, place the shift lever in the D
(Drive) position. The Approaching Vehicle Sound for Pedes-
trians (VSP) system is a function that uses
sound to help alert pedestrians of the
presence of the vehicle when it is being
driven at a low speed in the electric drive
mode under the following conditions:
.
The sound starts when the vehicle
starts accelerating.
. The sound stops when the vehicle
speed is more than 19 MPH (30 km/h)
while accelerating.
. The sound starts when the vehicle
speed is less than 16 MPH (25 km/h)
while decelerating.
. The sound stops when the vehicle
stops.
. The sound does not stop with the
vehicle in the R (Reverse) position even
if the vehicle stops.
The VSP system is automatically turned on
when the vehicle is in the READY to drive
mode.
If there is a malfunction in the VSP system,
the VSP OFF indicator light in the meter
illuminates. See “Approaching Vehicle
Sound for Pedestrians (VSP) OFF indicator
light” (P.2-18).
