move the shift lever to N (Neutral)
position

shift lock.
If the lever cannot be moved out of P
(Park), have an INFINITI retailer check the
automatic transmission system as soon as
possible.
Adaptive Shift Control (ASC)
The adaptive shift control system automa-
tically operates when the transmission is
in the D (Drive) position and selects an
appropriate gear depending on the road
conditions such as uphill, downhill or
curving roads.
Control on uphill and curving roads:
A low gear is maintained that suits the
degree of the slope or curve to allow
smooth driving with a small number of
shifts.
Control on downhill roads:
The adaptive shift control system shifts to
a low gear that suits the degree of the
slope, and uses the engine braking to
reduce the number of times that the brake must be used.
Control on winding roads:
A low gear is maintained on continuous
curves that involve repeated acceleration
and deceleration, so that smooth accelera-
tion is available instantly when the accel-
erator pedal is depressed.
NOTE:
. Adaptive shift control may not operate
when the transmission oil temperature
is low immediately after the start of
driving or when it is very hot.
. During some driving situations, hard
braking for example, the adaptive shift
control may automatically operate. The
transmission may automatically shift
to a lower gear for engine braking. This
increases engine speed but not vehicle
speed. Vehicle speed is controlled by
the accelerator pedal when the vehicle
is in the Adaptive shift control mode.
. When the adaptive shift control oper-
ates, the transmission sometimes
maintains a lower gear for a longer
period of time than when adaptive shift
control is not operating. Engine speed
will be higher for a specific vehicle
speed while ASC system is operating than when ASC is not operating.
NAVI Shift Control (if so equipped)
NAVI Shift Control automatically adjusts
the Automatic Transmission (AT) gear posi-
tion in certain situations based on road
information from the navigation system.
When the navigation system detects that
the vehicle is approaching a curved road,
NAVI Shift Control will adjust the gear
position if needed to help the driver run
through the curve smoothly.
Precaution on NAVI shift control:
.
The NAVI Shift Control does not provide
steering input or automated driving on
a curve. It is not a speed limit support
system and will not modify your speed
according to local speed limits.
. The NAVI Shift Control is a convenient
system intended to help the vehicle
move through a curve smoothly. How-
ever, the driver must always drive
safely and use the brake pedal if
needed.
. The NAVI Shift Control may be delayed
or not operate properly in the following
situations, because this function uses
the road information provided by the
navigation system.

The chassis control is an electric control
module that includes the following func-
tions:
.Log-in function (See “Log-in function”
(P.3-14).)
. INFINITI Drive Mode Selector (See
“ INFINITI Drive Mode Selector” (P.5-
21).)
. Active Lane Control (if so equipped)
(See “Active Lane Control” (P.5-24).)
. Active Trace Control (See “Active trace
control” (P.5-110).)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 32 8F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-8).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P.8-15).
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” (P.8-8).
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”(P.8-37) of this manual.
Intelligent All-Wheel Drive (AWD)
models
If you install snow tires, they must also be
the same size, brand, construction and

It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see“Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir. When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
.
Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from
moving. Move the shift lever to P (Park).
. Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
. Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
. If you must work with the engine
running, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts. .
It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
. Always wear eye protection whenever
you work on your vehicle.
. If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
. Never get under the vehicle while it is
supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key is in the OFF position and
the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
. The fuel filter or fuel lines should be
serviced by an INFINITI retailer because
the fuel lines are under high pressure
