HYBRID VEHICLE
CHARACTERISTICS
WARNING
●When you leave your vehicle, be sure to
place the ignition switch in the OFF
position.
● Be sure to put the transmission in the P
(Park) position because the vehicle can
move when the READY to drive indica-
tor light is on even if the gasoline en-
gine is not running. When the READY to
drive indicator light is on, do not leave
your vehicle in a shift position other
than the P (Park) position. The vehicle
will creep and start abruptly if the accel-
erator pedal is depressed by mistake.
This may cause serious injury or death.

Hydraulic brake system warning light
When the ignition switch is placed in the ON
position and the hybrid system is in the READY
mode, this light warns that the hydraulic brake
system is not functioning properly. If the brake
warning light comes on with the parking brake not
applied when the hybrid system is in READY
mode, perform the following:1. Check the brake fluid level. Add brake fluid as necessary. See “Brake fluid” in the Main-
tenance and do-it-yourself” section of your
INFINITI Owner’s Manual.
2. If the brake fluid level is correct, have the warning system checked by an INFINITI re-
tailer.
If the hydraulic brake warning light comes on
when the parking brake is not applied and the
electronically controlled brake system warning
light also comes on, stop the vehicle immediately
and call an INFINITI retailer.WARNING
● Your brake system may not be working
properly if the warning light is on. Driv-
ing could be dangerous. If you judge it
to be safe, drive carefully to the nearest
service station for repairs. Otherwise,
have your vehicle towed because driv-
ing it could be dangerous.
● Pressing the brake pedal with the en-
gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as pedal travel.
● If the brake fluid level is below the
MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked at an
INFINITI retailer. ●
Your brake system may not be working
properly if both the brake warning light
and electronically controlled brake sys-
tem light come on when the hybrid sys-
tem is in READY mode and the parking
brake is not applied. Driving could be
dangerous. If you judge it to be safe,
drive carefully to the nearest service
station for repairs. Otherwise, have your
vehicle towed because driving it could
be dangerous.
12–volt battery charge warning
light
If the light comes on when the READY indicator
comes ON, it may indicate the charging system is
not functioning properly. See an INFINITI retailer
immediately.
CAUTION
The charging system may not be function-
ing properly if the 12–volt battery charge
warning light comes on while the hybrid
system is running. The hybrid system will
stop operating when the 12–volt battery
becomes discharged. Immediately stop
the vehicle in a safe place and contact an
INFINITI retailer.

Hybrid system warning light
The hybrid system warning light comes on when:● The amount of fuel in the tank is getting low.
● There is a problem with the traction motor or
other hybrid system components.
If the fuel gauge indicates the fuel level is low,
refill the fuel tank immediately. See “Fuel gauge”
earlier in this section. After the fuel tank is filled,
the ignition switch is placed in the ON position,
and the hybrid system is in the READY mode, the
hybrid system warning light should be off.
If the fuel gauge indicates a sufficient fuel level, or
if the hybrid system warning light comes on after
refilling the tank, there may be a problem with the
traction motor or other hybrid system compo-
nents. Stop your vehicle immediately and contact
your INFINITI retailer.
Electronically controlled brake warning light (yellow)
When the ignition switch is placed in the ON
position and the hybrid system is in the READY
mode, the light stays on for about 2 seconds. If
the light comes on at any other time, it may
indicate the regenerative brake and/or the elec- tronically controlled brake systems are not func-
tioning properly. Have the system checked by an
INFINITI retailer.
If the hydraulic brake warning light also comes on
when the parking brake is not applied, stop the
vehicle
immediately and call an INFINITI re-
tailer. For additional information, see “Brake sys-
tem” in the “Starting and driving” section of the
INFINITI Owner’s Manual.
WARNING
● Your brake system may not be working
properly if both the brake warning light
and electronically controlled brake sys-
tem light come on when the hybrid sys-
tem is in READY mode and the parking
brake is not applied. Driving could be
dangerous. If you judge it to be safe,
drive carefully to the nearest service
station for repairs. Otherwise, have your
vehicle towed because driving it could
be dangerous.
