When the READY to drive indicator light
illuminates, the vehicle can be
driven, even if the gasoline engine is not
running.
NOTE:
The gasoline engine starts and stops
automatically. It may stop during low
speed driving, deceleration or when the
vehicle is stopped.
The gasoline engine may automatically
run in the following conditions:
. The level of remaining charge in the
Lithium ion (Li-ion) battery is low. The
engine runs to charge the Li-ion battery
and to provide power to the drive the
vehicle.
. The temperature of the engine coolant
is low. .
Based on driving conditions.
. The selector lever is shifted to the P
(Park) position, the driver ’s seat belt is
released and the driver ’s side door is
then opened.
The hybrid system operates as follows
based on driving conditions and the Li-ion
battery charge.STARTING AND SLOW SPEED DRIV-
ING
The vehicle is driven by the electric motor
depending on the available Li-ion battery
charge.
MEDIUM OR HIGH SPEED DRIVING
The system automatically controls the
gasoline engine and electric motor in order
to obtain the optimum fuel mileage and
performance, depending on the driving
situation and available Li-ion battery
charge.
When the remaining battery level is low,
the Li-ion battery is charged by the electric
motor that is driven to generate electric
power while the vehicle is driving.

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before
inserting it into the key hole or use the
Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 328F
(0 8C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” in the
“ 8. Maintenance and do-it-yourself ”sec-
tion.
12-VOLT BATTERY
If the 12-volt battery is not fully charged
during extremely cold weather conditions,
the 12-volt battery fluid may freeze and
damage the 12-volt battery. To maintain
maximum efficiency, the 12-volt battery
should be checked regularly. For additional
information, see “12-volt battery ”in the
“ 8. Maintenance and do-it-yourself ”sec-
tion.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“ Engine cooling system” in the“8. Main-
tenance and do-it-yourself ”section and
“ Inverter cooling system” in the“8. Main-
tenance and do-it-yourself ”section.
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels.
Consult an INFINITI retailer for the tire
type, size, speed rating and availability
information.
For additional traction on icy roads,
studded tires may be used. However, some
U.S. states and Canadian provinces prohi-
bit their use. Check local, state and
provincial laws before installing studded
tires. Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow
tires.
Tire chains may be used. For details, see
“
Tire chains ”in the “8. Maintenance and
do-it-yourself ”section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
. A scraper and stiff-bristled brush to
remove ice and snow from the windows
and wiper blades.
. A sturdy, flat board to be placed under
the jack to give it firm support.
. A shovel to dig the vehicle out of
snowdrifts.
. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
. Wet ice (328 F, 08C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip ”under
