WARNING
.Always have the doors locked while
driving. Along with the use of seat
belts, this provides greater safety in
the event of an accident by helping to
prevent persons from being thrown
from the vehicle. This also helps keep
children and others from unintention-
ally opening the doors, and will help
keep out intruders.
. Before opening any door, always look
for and avoid oncoming traffic.
. To help avoid risk of injury or death
through unintended operation of the
vehicle and or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets
unattended in your vehicle. Addition-
ally, the temperature inside a closed
vehicle on a warm day can quickly
become high enough to cause a sig-
nificant risk of injury or death to
people and pets.
CAUTION
To prevent theft or accidents, be sure to
stop the engine and lock the doors
before stepping away from the vehicle.

. If you see steam or smoke coming
from the engine compartment, to
avoid injury do not open the hood.
Pre-driving checks and adjustments3-17
HOOD

THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
.The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials away
from the exhaust system compo-
nents.
. Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
CAUTION
.Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
the three-way catalyst’s ability to
help reduce exhaust pollutants.
. Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly. It is recommended
you visit an INFINITI retailer for this
service.
. Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the three-way catalyst.
. Do not race the engine while warming
it up.
. Do not push or tow your vehicle to
start the hybrid system.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.) As an added safety feature, your vehicle has
been equipped with a Tire Pressure Mon-
itoring System (TPMS) that illuminates a low
tire pressure telltale when one or more of
your tires is significantly under-inflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a sub-
stitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct
tire pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously illumi-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may not

.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 appearance
and condition. Also check tires for proper
inflation.
. Lock all doors.
. Position seat and adjust head restraints.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passengers
to do likewise.
. Check the operation of warning lights
when the ignition switch is pushed to the
ON position. (See “Warning lights, in-
dicator lights and audible reminders”
(P.2-10).) 1. Apply the parking brake.
2. Move the shift lever to P (Park) position.
The INFINITI Direct Response Hybrid
®
System is designed not to operate if the
shift lever is not in the P (Park) position.
3. Depress the brake pedal and push the ignition switch to start the hybrid sys-
tem. The READY to drive indicator light
will illuminate on the meter.
When starting the hybrid system at very
low outside temperatures, the READY
to drive indicator light will flash and it
may take longer for the READY to drive
indicator light to illuminate.
. The hybrid system may not start even
with the READY to drive indicator light
illuminated. Once the READY to drive
indicator light is illuminated you may
begin driving the vehicle.
. You may hear a sound in the engine
compartment when the brake pedal is
depressed with the hybrid system off.
This does not indicate a problem.
NOTE:
Care should be taken to avoid situations
that can lead to potential 12-volt battery
discharge and potential no-start conditions
such as:
1. Installation or extended use of electro-
nic accessories that consume 12-volt battery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the 12-volt battery may
need to be charged to maintain 12-volt
battery health.

up or down.
When shifting up, move the shift lever to the
+ (up) side. The transmission shifts to the
higher range.
When shifting down, move the shift lever to
the − (down) side. The transmission shifts to
the lower range.
When canceling the manual shift mode,
return the shift lever to the D (Drive)
position. The transmission returns to the
normal driving mode.
In the manual shift mode, the shift range is
displayed on the position indicator in the
meter.
Shift ranges up or down one by one as
follows:
M1?
/M2 ?
/M3?
/M4 ?
/M5?
/M6?
/M7
M7 (7th):
Use this position for all normal forward
driving at highway speeds.
M6 (6th) andM5 (5th):
Use these positions when driving up long
slopes, or for engine braking when driving
down long slopes.
M4 (4th),M3 (3rd) andM2 (2nd):
Use these positions for hill climbing or engine
braking on downhill grades.
M1 (1st):
Use this position when climbing steep hills
slowly or driving slowly through deep snow,
or for maximum engine braking on steep
downhill grades.
. Remember not to drive at high speeds for
extended periods of time in lower than
7th gear. This reduces fuel economy.
. Moving the shift lever rapidly to the same
side twice will shift the ranges in succes-
sion.
. In the manual shift mode, the transmis-
sion may not shift to the selected gear
or may automatically shift to the other
gear. This helps maintain driving per-
formance and reduces the chance of
vehicle damage or loss of control.
When the transmission does not shift to
the selected gear, the Automatic Trans-
mission (AT) position indicator light (on
the vehicle information display) will
blink and the chime will sound.
. In the manual shift mode, the transmis-
sion automatically shifts down to 1st
gear before the vehicle comes to a stop.
When accelerating again, it is necessary
to shift up to the desired range.Accelerator downshift — In D (Drive)
position —
For passing or hill climbing, fully depress the
accelerator pedal to the floor. This shifts the
transmission down into the lower gear,
depending on the vehicle speed.
Fail-safe
When the fail-safe operation occurs, note
that the transmission will be locked in any of
the forward gears according to the condi-
tion.
If the vehicle is driven under extreme
conditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, push the ignition
switch to the OFF position and wait for 3
seconds. Then push the ignition switch back
to the ON position. The vehicle should
return to its normal operating condition. If
it does not return to its normal operating
condition, have the transmission checked
and repaired, if necessary. It is recom-
mended you visit an INFINITI retailer for
this service.

Shift lock release
If the 12-volt battery charge is low or
discharged, the shift lever may not be moved
from the P (Park) position even with the
brake pedal depressed and the shift lever
button pushed.
To move the shift lever, perform the follow-
ing procedure:
1. Push the ignition switch to the OFF orLOCK position.
2. Apply the parking brake.
3. Remove the shift lock cover
using a
suitable tool.
4. Push down the shift lock
as illustrated. 5. Push the shift lever button
and move
the shift lever to N (Neutral) position
while holding down the shift lock.
Push the ignition switch to the ON position
to unlock the steering wheel (if so equipped).
Now the vehicle may be moved to the
desired location.
For models with a steering wheel lock
mechanism:
If the 12-volt battery is discharged comple-
tely, the steering wheel cannot be unlocked.
Do not move the vehicle with the steering
wheel locked.
If the lever cannot be moved out of P (Park),
have the automatic transmission system
checked as soon as possible. It is recom-
mended you visit an INFINITI retailer for this
service.
Adaptive shift control (ASC)
The adaptive shift control system automati-
cally 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 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 main-
tains a lower gear for a longer period of
time than when adaptive shift control is
not operating. Engine speed will be

PRECAUTIONS ON CRUISE
CONTROL
.If the cruise control system malfunctions,
it will cancel automatically. The SET
indicator on the vehicle information dis-
play will then blink to warn the driver.
. If the engine coolant temperature be-
comes excessively high, the cruise con-
trol system will be canceled
automatically.
. If the SET indicator blinks, turn the cruise
control main switch off and have the
system checked. It is recommended you
visit an INFINITI retailer for this service.
. The SET indicator may sometimes blink
when the cruise control main switch is
turned ON while pushing the ACCEL-
ERATE/RESUME, COAST/SET or
CANCEL switch. To properly set the
cruise control system, perform the steps
below in the order indicated.
WARNING
Do not use the cruise control when
driving under the following conditions:
. when it is not possible to keep the
vehicle at a set speed .
in heavy traffic or in traffic that
varies in speed
. on winding or hilly roads
. on slippery roads (rain, snow, ice,
etc.)
. in very windy areas
Doing so could cause a loss of vehicle
control and result in an accident.

5-122Starting and driving
illuminates the ABS warning light on the
instrument panel. The brake system then
operates normally, but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the
vehicle checked. It is recommended you visit
an INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsation
in the brake pedal and hear a noise from
under the hood or feel a vibration from the
actuator when it is operating. This is normal
and indicates that the ABS is operating
properly. However, the pulsation may indi-
cate that road conditions are hazardous and
extra care is required while driving.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving
conditions, the VDC system helps to perform
the following functions.
.
Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power
is transferred to a non slipping drive
wheel on the same axle.
. Controls brake pressure and engine or
mortor output to reduce drive wheel slip
based on vehicle speed (traction control
function).
. Controls brake pressure at individual
wheels and engine or motor output to
help the driver maintain control of the
vehicle in the following conditions:
— understeer (vehicle tends to not follow the steered path despite increased
steering input)
— oversteer (vehicle tends to spin due to certain road or driving conditions).
The VDC system can help the driver to
maintain control of the vehicle, but it cannot
prevent loss of vehicle control in all driving
situations.
When the VDC system operates, the VDC
warning light
in the instrument panel
flashes so note the following:
. The road may be slippery or the system
may determine some action is required to help keep the vehicle on the steered path.
. You may feel a pulsation in the brake
pedal and hear a noise or vibration from
under the hood. This is normal and
indicates that the VDC system is working
properly.
. Adjust your speed and driving to the road
conditions.
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-17).
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system automa-
tically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator light
illuminates to indicate the VDC system is off.
When the VDC switch is used to turn off the
system, the VDC system still operates to
prevent one drive wheel from slipping by
transferring power to a non slipping drive
wheel. The VDC warning light
flashes if
this occurs. All other VDC functions are off,
except for rise-up and build-up and brake
force distribution, and the VDC warning
light
will not flash. The VDC system is
automatically reset to on when the ignition
switch is placed in the OFF position then
back to the on position.

ing light” (P.2-17) and “Vehicle Dynamic

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 insert-
ing 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°F
(0°C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-5).
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” (P.8-13).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For details, see “Engine cooling
system” (P.8-5) and “Inverter cooling sys-
tem” (P.8-7).
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. It is
recommended you consult an INFINITI re-
tailer 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 prohibit 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.8-32).
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 (32°F, 0°C 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 these conditions. Try to avoid
driving on wet ice until the road is
salted or sanded.
. Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels will
lose even more traction.
. Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pave-
ment.
. Allow greater following distances on
slippery roads.

COLD WEATHER DRIVING

3. If engine overheating is caused by climb-ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator before opening the hood. (If
steam or coolant is escaping, turn off the
hybrid system.) Do not open the hood
further until no steam or coolant can be
seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Also check if the cooling fan is running. The radiator hoses and radiator should
not leak water. If coolant is leaking or the
cooling fan does not run, stop the hybrid
system.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling
fan can start at any time.
7. After the engine cools down, check the coolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired. It is recommended you
visit an INFINITI retailer for this service. When towing your vehicle, all State (Pro-
vincial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle. Tow-
ing instructions are available from an
INFINITI retailer. Local service operators
are familiar with the applicable laws and
procedures for towing. To assure proper
towing and to prevent accidental damage to
your vehicle, INFINITI recommends that you
have a service operator tow your vehicle. It is
advisable to have the service operator care-
fully read the following precautions.
WARNING
.
Never ride in a vehicle that is being
towed.
. Never get under your vehicle after it
has been lifted by a tow truck.
CAUTION
.When towing, make sure that the
transmission, axles, steering system
and powertrain are in working con-
dition. If any unit is damaged, dollies
must be used.
. Always attach safety chains before
