OPERATING RANGE FOR ENGINE
START FUNCTION
The Intelligent Key can only be used for
starting the engine when the Intelligent
Key is within the specified operating range.
When the Intelligent Key battery is almost
discharged or strong radio waves are
present near the operating location, the
Intelligent Key system’s operating range
becomes narrower and may not function
properly.
If the Intelligent Key is within the operating
range, it is possible for anyone, even
someone who does not carry the IntelligentKey, to push the ignition switch to start the
engine.
.
The trunk area is not included in the
operating range but the Intelligent Key
may function.
. If the Intelligent Key is placed on the
instrument panel, rear parcel shelf,
inside the glove box or door pocket,
the Intelligent Key may not function.
. If the Intelligent Key is placed near the
door or window outside the vehicle, the
Intelligent Key may function.

5-12Starting and driving
If the battery of the vehicle is discharged,
the push-button ignition switch cannot be
turned from the LOCK position.
Some indicators and warnings for opera-
tion are displayed in the vehicle informa-
tion display between the speedometer and
tachometer. (See“Vehicle information dis-
play” (P.2-20).)
The ignition lock is designed so that the
ignition switch position cannot be switched
to LOCK until the shift lever is moved to the
P (Park) position.
When the ignition switch cannot be pushed
toward the LOCK position, proceed as
follows:
1. Move the shift lever into the P (Park) position.
2. Push the ignition switch to the OFF position. The ignition switch position
indicator will not illuminate.
3. Open the door. The ignition switch will change to the LOCK position.
The shift lever can be moved from the P
(Park) position if the ignition switch is in
the ON position and the brake pedal is
depressed.PUSH-BUTTON IGNITION SWITCH
POSITIONS
LOCK (Normal parking position)
The ignition switch can only be locked in
this position.
The ignition switch will be unlocked when
it is pushed to the ACC position while
carrying the Intelligent Key.
ACC (Accessories)
This position activates electrical acces-
sories such as the radio, when the engine
is not running.
ON (Normal operating position)
This position turns on the ignition system
and electrical accessories.
OFF
The engine can be turned off in this
position.
The ignition lock is designed so that the
ignition switch cannot be switched to the
LOCK position until the shift lever is moved
to the P (Park) position.
CAUTION
Do not leave the vehicle with the push-
button ignition switch in ACC or ON posi-
tions when the engine is not running for an
extended period. This can discharge the
battery.

INTELLIGENT KEY BATTERY DIS-
CHARGE
If the battery of the Intelligent Key is
discharged, or environmental conditions
interfere with the Intelligent Key operation,
start the engine according to the following
procedure:
1. Move the shift lever to the P (Park)position.
2. Firmly apply the foot brake.
3. Touch the ignition switch with the Intelligent Key as illustrated. (A chime

After step 3 is performed, when the
ignition switch is pushed without depres-
sing the brake pedal, the ignition switch
position will change to ACC.
NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the engine is
started by the above procedures, the
Intelligent Key battery discharge indi-
cator appears in the vehicle informa-
tion display even if the Intelligent Key
is inside the vehicle. This is not a
malfunction. To turn off the Intelligent
Key battery discharge indicator, touch
the ignition switch with the Intelligent
Key again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery
as soon as possible. (See “Intelligent
Key battery replacement” (P.8-24).).
Make sure the area around the vehicle
is clear.
. Check fluid levels such as engine oil,
coolant, brake fluid and window
washer fluid as frequently as possible,
or at least whenever you refuel.
. Check that all windows and lights are
clean.
. Visually inspect tires for their appear-
ance and condition. Also check tires for
proper inflation.
. Lock all doors.
. Position seat and adjust head re-
straints.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passen-
gers to do likewise.
. Check the operation of warning lights
when the ignition switch is pushed to
the ON position. (See “Warning/indica-
tor lights and audible reminders” (P.2-
12).)

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.
