designed to indicate a low oil level. Use the
dipstick to check the oil level.(See “Engine
oil” (P.8-8).)
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.
Forward Emergency Braking
(FEB) system warning light (if so
equipped)
This light comes on when the ignition switch
is placed in the ON position. It turns off after
the hybrid system is started.
This light illuminates when the Forward
Emergency Braking (FEB) system is set to
OFF on the center display.
If the light illuminates when the FEB system
is ON, it may indicate that the system is
unavailable. See “Forward Emergency Brak-
ing (FEB)” (P.5-101) for more details.
This light will also illuminates if the Active
Trace Control is malfunctioning. Although the vehicle is still driveable under normal
conditions, have the vehicle checked. It is
recommended you visit an INFINITI retailer
for this service. (See “Vehicle Dynamic Con-
trol (VDC) system” (P.5-122).)
High temperature warning
light
When the ignition switch is in the ON
position, the high temperature warning light
illuminates and then turns off. This indicates
that the high temperature sensor in the
engine coolant system is operational.
CAUTION
If the high temperature warning light
illuminates when the ignition switch is in
the ON position, it may indicate the
engine temperature is extremely high.
Stop the vehicle safety as soon as
possible.
If the vehicle is overheated, continuing
vehicle operation may seriously damage
the engine. (See “If your vehicle over-
heats” (P.6-12) for the immediate action
required.)
Hybrid EPS (Electrical Power
Steering) warning light
When the ignition switch is in the ON
position, the Hybrid EPS (Electrical Power
Steering) warning light illuminates. After
starting the hybrid system, the Hybrid EPS
warning light turns off. This indicates that
the electrical power steering system is
operational.
If the Hybrid EPS warning light illuminates
while the hybrid system is running, it may
indicates the Hybrid EPS system is not
functioning properly and may need servicing.
Have the Hybrid EPS system checked. It is
recommended you visit an INFINITI retailer
for this service.
When the Hybrid EPS warning light illumi-
nates with the hybrid system running, the
power assist to the steering will cease
operation but you will still have control of
the vehicle. At this time, greater steering
efforts are required to operate the steering
wheel, especially in sharp turns and at low
speeds. However, if the steering wheel
operation is still performed, the Hybrid EPS
may stop and the Hybrid EPS warning light
will illuminate. Place the ignition switch in
the OFF position. For a while after it refrains
from the steering wheel control, the tem-
perature of the Hybrid EPS system will go

.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.

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
Starting and driving5-17

4. Drive at economical speeds and dis-tances.
.Observing the speed limit and notexceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel
efficiency due to reduced aerody-
namic drag.
.Maintaining a safe following distance
behind other vehicles reduces unne-
cessary braking.
.Safely monitoring traffic to anticipatechanges in speed permits reduced
braking and smooth acceleration
changes.
.Select a gear range suitable to roadconditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady speed.
.Cruise control is particularly effectivein providing fuel savings when driving
on flat terrains.
6. Plan for the shortest route.
.Utilize a map or navigation system to determine the best route to save time.
7. Avoid idling.
.Shutting off your engine when safe for stops exceeding 30-60 seconds
saves fuel and reduces emissions. 8. Buy an automated pass for toll roads.
.Automated passes permit drivers to
use special lanes to maintain cruising
speed through the toll and avoid
stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to fuel economy.
.Vehicles typically need no more than30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal oper-ating temperature more quickly while
driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking area or in the shade whenever possi-
ble.
.When entering a hot vehicle, openingthe windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system. .
Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases tire
wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
. Use the recommended viscosity engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-5).)
Starting and driving5-117
INCREASING FUEL ECONOMY

.Do not use a wax containing any abra-
sives, cutting compounds or cleaners
that may damage the vehicle finish.
Machine compounding or aggressive polish-
ing on a base coat/clear coat paint finish
may dull the finish or leave swirl marks.
REMOVING SPOTS
Remove tar and oil spots, industrial dust,
insects, and tree sap as quickly as possible
from the paint surface to avoid lasting
damage or staining. Special cleaning pro-
ducts are available at an INFINITI retailer or
any automotive accessory stores.
UNDERBODY
In areas where road salt is used in winter, the
underbody must be cleaned regularly. This
will prevent dirt and salt from building up
and causing the acceleration of corrosion on
the underbody and suspension. Before the
winter period and again in the spring, the
underseal must be checked and, if necessary,
re-treated.
GLASS
Use glass cleaner to remove smoke and dust
film from the glass surfaces. It is normal for
glass to become coated with a film after the
vehicle is parked in the hot sun. Glass cleaner
and a soft cloth will easily remove this film.
CAUTION
When cleaning the inside of the win-
dows, do not use sharp-edged tools,
abrasive cleaners or chlorine-based dis-
infectant cleaners. They could damage
the electrical conductors, radio antenna
elements or rear window defroster ele-
ments.
WHEELS
Wash the wheels when washing the vehicle
to maintain their appearance.
. Clean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
. Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
. INFINITI recommends that the road
wheels be waxed to protect against road
salt in areas where it is used during winter.
CAUTION
Do not use abrasive cleaners when
washing the wheels.
Aluminum alloy wheels
Wash regularly with a sponge dampened in a
mild soap solution, especially during winter
months in areas where road salt is used. Salt
could discolor the wheels if not removed.
CAUTION
Follow the directions below to avoid
staining or discoloring the wheels:
.
Do not use a cleaner that uses strong
acid or alkali contents to clean the
wheels.
. Do not apply wheel cleaners to the
wheels when they are hot. The wheel
temperature should be the same as
ambient temperature.
. Rinse the wheel to completely re-
move the cleaner within 15 minutes
after the cleaner is applied.

8-2Do-it-yourself
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
.This vehicle has high voltage DC and
AC systems as well as a 12-volt
system. DC and AC high voltage is
very dangerous and can cause severe
burns and electric shock that may
result in serious injury or death.
. Never touch, disassemble, remove or
replace the high voltage parts, har-
nesses and their connectors. High
voltage cables are orange. Touching,
disassembling, removing or replacing
those parts and harnesses can cause
severe burns or electric shock that
may result in serious injury or death.
. Never try to remove the service plug
located in the trunk room. The service
plug is used only when the vehicle is
serviced by trained technicians wear-
ing personal protection equipment
and is part of the high voltage
system. Touching the service plug
can cause severe burns or electric shock that may result in serious injury
or death.
. The INFINITI Direct Response Hy-
brid
®System uses high voltage up to
408 volts. The system can be hot
while and after starting. Be careful of
both the high voltage and the high
temperature. Obey the caution labels
attached to the vehicle.
. 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 per-
forming any parts replacement or
repairs.
. The engine can start at any time
without warning when the hybrid
system is in the READY to drive
mode. If you must work with the
Hybrid System in the READY to drive
mode, keep your hands, clothing, hair
and tools away from fans, belts and
any other parts that can move.
. 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 when-
ever you work on your vehicle.
. Your vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.
. 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 the fuel tank and
battery.
CAUTION
.Do not work under the hood while the
engine is hot. Turn the hybrid system
off and wait until it cools down.
. Avoid direct contact with used en-
gine oil and coolant. Improperly dis-
