four wheel drive INFINITI G37 2010 Owners Manual

WARNING● If the light does not illuminate with the ignition
switch pushed ON, have the vehicle checked
by an INFINITI retailer as soon as possible.
● If the light illuminates while driving, avoid
sudden steering maneuvers or abrupt brak-
ing, reduce vehicle speed, pull off the road to
a safe location and stop the vehicle as soon
as possible. Driving with under-inflated tires
may permanently damage the tires and in-
crease the likelihood of tire failure. Serious
vehicle damage could occur and may lead to
an accident and could result in serious per-
sonal injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the rec-
ommended COLD tire pressure shown on the
Tire and Loading Information label to turn
the low tire pressure warning light OFF. If the
light still illuminates while driving after ad-
justing the tire pressure, a tire may be flat. If
you have a flat tire, replace it with a spare
tire as soon as possible.
● When a spare tire is mounted or a wheel is
replaced, the TPMS will not function and the
low tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after the 1 minute. Contact your
INFINITI retailer as soon as possible for tire
replacement and/or system resetting. ● Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
CAUTION● The TPMS is not a substitute for the regular
tire pressure check. Be sure to check the tire
pressure regularly.
● If the vehicle is being driven at speeds of less
than 16 MPH (25 km/h), the TPMS may not
operate correctly.
● Be sure to install the specified size of tires to
the four wheels correctly.
Master warning light When the ignition switch is in the ON position,
the master warning light illuminates if any of
the following are displayed on the dot matrix
liquid crystal display:
● No key warning
● Low fuel warning
● Low washer fluid warning
● Parking brake release warning
● Door/trunk open warning ● Loose fuel cap warning (if so equipped)
● Check tire pressure warning (if so equipped)
See “DOT MATRIX LIQUID CRYSTAL DISPLAY”
later in this section.
Preview Function warning
light (orange; if so equipped) The light comes on if there is a malfunction in the
Brake Assist (with Preview Function) system.
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine, resume driving and set the ICC system
again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the sys-
tem is malfunctioning. Although the vehicle is
still driveable under normal conditions, have the
vehicle checked at an INFINITI retailer.

Additional information ● The TPMS does not monitor the tire pressure
of the spare tire.
● The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH (25 km/h).
Also, this system may not detect a sudden
drop in tire pressure (for example a flat tire
while driving).
● The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After the tire is inflated to the
recommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h) to
activate the TPMS and turn off the low tire
pressure warning light. Use a tire pressure
gauge to check the tire pressure.
● Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. Low outside
temperature can lower the temperature of
the air inside the tire which can cause a
lower tire inflation pressure. This may cause
the low tire pressure warning light to illumi-
nate. If the warning light illuminates in low
ambient temperature, check the tire pres-
sure for all four tires. For additional information, see “Low tire pres-
sure warning light” in the “2. Instruments and
controls” section and “TIRE PRESSURE MONI-
TORING SYSTEM (TPMS)” in the “6. In case of
emergency” section.
WARNING● If the low tire pressure warning light illumi-
nates while driving, avoid sudden steering
maneuvers or abrupt braking, reduce vehicle
speed, pull off the road to a safe location and
stop the vehicle as soon as possible. Driving
with under-inflated tires may permanently
damage the tires and increase the likelihood
of tire failure. Serious vehicle damage could
occur and may lead to an accident and could
result in serious personal injury. Check the
tire pressure for all four tires. Adjust the tire
pressure to the recommended COLD tire
pressure shown on the Tire and Loading In-
formation label to turn the low tire pressure
warning light OFF. If the light still illumi-
nates while driving after adjusting the tire
pressure, a tire may be flat. If you have a flat
tire, replace it with a spare tire as soon as
possible. (See “FLAT TIRE” in the “6. In case
of emergency” section for changing a flat
tire.) ● When a spare tire is mounted or a wheel is
replaced, the TPMS will not function and the
low tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
● Do not inject any tire liquid or aerosol tire
sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
CAUTION● The TPMS may not function properly when
the wheels are equipped with tire chains or
the wheels are buried in snow.
● Do not place metalized film or any metal
parts (antenna, etc.) on the windows. This
may cause poor reception of the signals from
the tire pressure sensors, and the TPMS will
not function properly.

Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter,
prescription, and illegal drugs). Don’t drive if
your ability to operate your vehicle is impaired
by alcohol, drugs, or some other physical con-
dition.
ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS WARNING● Do not drive beyond the performance capa-
bility of the tires, even with AWD engaged.
Accelerating quickly, sharp steering maneu-
vers or sudden braking may cause loss of
control.
● Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
Install tire chains on the rear wheels when
driving on slippery roads and drive carefully.
● This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in. ● For AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any D (Drive) or R (Re-
verse) position with the engine running. Do-
ing so may result in drivetrain damage or
unexpected vehicle movement which could
result in serious vehicle damage or personal
injury.
● Do not attempt to test an AWD equipped ve-
hicle on a 2-wheel dynamometer, (such as
the dynamometers used by some states for
emissions testing), or similar equipment
even if the other two wheels are raised off
the ground. Make sure you inform test facil-
ity personnel that your vehicle is equipped
with AWD before it is placed on a dynamom-
eter. Using the wrong test equipment may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
● When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively. WARNINGDo not operate the push-button ignition switch
while driving the vehicle except in an emer-
gency. (The engine will stop when the ignition
switch is pushed 3 consecutive times or the
ignition switch is pushed and held for more
than 2 seconds.) If the engine stops while the
vehicle is being driven, this could lead to a
crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the selector lever to the
P (Park) position (for automatic transmission
model) or the shift lever to the N (Neutral)
position (for manual transmission model).PUSH-BUTTON IGNITION SWITCH

ANTI-LOCK BRAKING SYSTEM (ABS) WARNING● The Anti-lock Braking System (ABS) is a so-
phisticated device, but it cannot prevent ac-
cidents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. Remember that stopping distances on
slippery surfaces will be longer than on nor-
mal surfaces even with ABS. Stopping dis-
tances may also be longer on rough, gravel
or snow covered roads, or if you are using
tire chains. Always maintain a safe distance
from the vehicle in front of you. Ultimately,
the driver is responsible for safety.
● Tire type and condition may also affect brak-
ing effectiveness.
– When replacing tires, install the specified
size of tires on all four wheels.
– When installing a spare tire, make sure that
it is the proper size and type as specified on
the Tire and Loading Information label. See
“TIRE AND LOADING INFORMATION LABEL”
in the “9. Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “WHEELS
AND TIRES” in the “8. Maintenance and
do-it-yourself” section of this manual. The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the system Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
WARNINGDo not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and move the vehicle at a low speed in forward or reverse. When the self-test occurs,
you may hear a “clunk” noise and/or feel a
pulsation in the brake pedal. This is normal and
does not indicate a malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by an INFINITI retailer.
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 pressure. 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 pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.

● Do not modify the vehicle’s suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars, bushings
and wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, the VDC system may not operate prop-
erly. This could adversely affect vehicle han-
dling performance, and the indicator
may flash or both and indicator
lights may illuminate.
● If brake related parts such as brake pads,
rotors and calipers are not INFINITI recom-
mended or are extremely deteriorated, the
VDC system may not operate properly and
both and indicator lights may
illuminate.
● If engine control related parts are not
INFINITI recommended or are extremely de-
teriorated, both the and indica-
tor lights may illuminate.
● When driving on extremely inclined surfaces
such as higher banked corners, the VDC sys-
tem may not operate properly and the
indicator may flash or both and
indicator lights may illuminate. Do not drive
on these types of roads. ● When driving on an unstable surface such as
a turntable, ferry, elevator or ramp, the
indicator may flash or both and
indicator lights may illuminate. This
is not a malfunction. Restart the engine after
driving onto a stable surface.
● If wheels or tires other than the INFINITI rec-
ommended ones are used, the VDC system
may not operate properly and the in-
dicator may flash or both and
indicator lights may illuminate.
● The VDC system is not a substitute for winter
tires or tire chains on a snow covered road. The 4 Wheel Active Steer (4WAS) system is an
electronically controlled four-wheel steering
system.
Depending on the vehicle speed and steering
angle, the angles of the front and rear wheels
are adjusted by the 4WAS system to help
improve driving performance.
If a malfunction occurs in the system, the 4WAS
function will stop but the ordinary two-wheel
steering system will operate normally. The
“4WAS” warning light will illuminate. If the light
illuminates while you are driving, contact an
INFINITI retailer for repair.
The steering wheel may be slightly turned even
when driving on a straight road due to a
protection mechanism for the 4WAS system.
This is not a malfunction. The steering wheel
will return to the normal position after the
protection mechanism deactivates.
The protection mechanism activates under the
following conditions:
● The steering wheel is operated forcibly when
it is hard to operate or the tires are blocked
by obstacles.
● The steering wheel is continuously operated
when the vehicle is parked or being driven at
extremely low speed.4 WHEEL ACTIVE STEER (4WAS) SYSTEM (if
so equipped)

● The steering wheel is forcibly turned beyond
its operation limits.
● The battery voltage is reduced.
Repeated steering maneuvers that may activate
the protection mechanism will damage the
4WAS system.
WARNINGThe 4WAS system, although a sophisticated
device, cannot prevent accidents resulting
from careless or dangerous driving techniques.
Ultimately the responsibility for safety of self
and others rests in the hands of the driver.
Therefore only through attentive and careful
driving methods can the 4WAS system be fully
appreciated and safety optimized. 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°F (0°C),
check antifreeze to assure proper winter protec-
tion. For additional information, see “ENGINE
COOLING SYSTEM” in the “8. Maintenance and
do-it-yourself” section.
BATTERY If the battery is not fully charged during ex-
tremely 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” in the “8. Mainte-
nance and do-it-yourself” section.
DRAINING OF COOLANT WATER If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see “ENGINE COOLING SYS-
TEM” in the “8. Maintenance and do-it-yourself”
section. TIRE EQUIPMENT SUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. 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 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” in the “8. Maintenance and do-it-
yourself” section of this manual.
For all-wheel drive If you install snow tires, they must also be the
same size, brand, construction and tread pat-
tern on all four wheels.COLD WEATHER DRIVING

In the event of a roadside emergency, Roadside
Assistance Service is available to you. Please
refer to your Warranty Information Booklet
(U.S.) or Warranty & Roadside Assistance Infor-
mation Booklet (Canada) for details.
Emergency engine shut off To shut off the engine in an emergency situation
while driving perform the following procedure:
− Rapidly push the push-button ignition switch
3 consecutive times, or
− Push and hold the push-button ignition for
more than 2 seconds.
TIRE PRESSURE MONITORING SYSTEM
(TPMS) This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires except the spare. When the
low tire pressure warning light is lit, one or
more of your tires is significantly under-
inflated. If the vehicle is being driven with low
tire pressure, the TPMS will activate and warn
you of it by the low tire pressure warning light.
This system will activate only when the vehicle
is driven at speeds above 16 MPH (25 km/h). For
more details, see “WARNING/INDICATOR LIGHTS
AND AUDIBLE REMINDERS” in the “2. Instru-
ments and controls” section and “TIRE PRES-
SURE MONITORING SYSTEM (TPMS)” in the “5.
Starting and driving” section. WARNING● If the low tire pressure warning light illumi-
nates while driving, avoid sudden steering
maneuvers or abrupt braking, reduce vehicle
speed, pull off the road to a safe location and
stop the vehicle as soon as possible. Driving
with under-inflated tires may permanently
damage the tires and increase the likelihood
of tire failure. Serious vehicle damage could
occur and may lead to an accident and could
result in serious personal injury. Check the
tire pressure for all four tires. Adjust the tire
pressure to the recommended COLD tire
pressure shown on the Tire and Loading In-
formation label to turn the low tire pressure
warning light OFF. If the light still illumi-
nates while driving after adjusting the tire
pressure, a tire may be flat. If you have a flat
tire, replace it with a spare tire as soon as
possible.
● When a spare tire is mounted or a wheel is
replaced, the TPMS will not function and the
low tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting.ROADSIDE ASSISTANCE PROGRAM FLAT TIRE

TOWING RECOMMENDED BY INFINITI
Two-Wheel Drive (2WD) models INFINITI recommends that your vehicle be towed
with the driving (rear) wheels off the ground or
place the vehicle on a flat bed truck as illustrated.
CAUTION● Never tow automatic transmission models
with the rear wheels on the ground or four
wheels on the ground (forward or backward),
as this may cause serious and expensive damage to the transmission. If it is neces-
sary to tow the vehicle with the front wheels
raised, always use towing dollies under the
rear wheels.
● When towing rear wheel drive models with the
front wheels on the ground or on towing dol-
lies: Push the ignition switch to the ACC or ON
position, and secure the steering wheel in a
straight-ahead position with a rope or similar
device. Never secure the steering wheel by
selecting the LOCK position. This may damage
the steering lock mechanism. ● If you have to tow manual transmission mod-
els with the rear wheels on the ground (if you
do not use towing dollies) or four wheels on
the ground:
– Push the ignition switch to the ON posi-
tion and turn off all accessories.
– Always release the parking brake.
– Move the transmission shift lever to the N
(Neutral) position.
– Observe the following restricted towing
speeds and distances for manual trans-
mission models only:
● Rear wheels on the ground:
Speed: Below 50 MPH (80 km/h)
Distance: Less than 50 miles (80 km)
● Four wheels on the ground:
Speed: Below 70 MPH (112 km/h)
Distance: Less than 500 miles (800 km)
– If the speed or distance must necessarily
be greater, remove the propeller shaft be-
fore towing to prevent damage to the
transmission.Two-wheel drive models SCE0788

● For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
All season tires INFINITI specifies all season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All
Season tires are identified by ALL SEASON
and/or M&S (Mud and Snow) on the tire side-
wall. Snow tires have better snow traction than
All Season tires and may be more appropriate in
some areas.
Summer tires INFINITI specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance is substantially re-
duced in snow and ice. Summer tires do not
have the tire traction rating M&S on the tire
sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, INFINITI recommends the use of
SNOW tires or ALL SEASON tires on all four
wheels. Snow tires If snow tires are needed, it is necessary to
select tires equivalent in size and load rating to
the original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of the
tire.
If you install snow tires, they must be the same
size, brand, construction and tread pattern on
all four wheels.
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 capa-
bilities of studded snow tires, on wet or dry
surfaces, may be poorer than that of non-
studded snow tires. TIRE CHAINS Use of tire chains may be prohibited according
to location. Check the local laws before install-
ing tire chains. When installing tire chains,
make sure they are the proper size for the tires
on your vehicle and are installed according to
the chain manufacturer’s suggestions. Use only
SAE Class S chains. Class “S” chains are used
on vehicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains are
designed to meet the SAE standard minimum
clearances between the tire and the closest
vehicle suspension or body component re-
quired to accommodate the use of a winter
traction device (tire chains or cables). The mini-
mum clearances are determined using the fac-
tory equipped tire size. Other types may dam-
age your vehicle. Use chain tensioners when
recommended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the tire
chain must be secured or removed to prevent
the possibility of whipping action damage to
the fenders or underbody. If possible, avoid
fully loading your vehicle when using tire
chains. In addition, drive at a reduced speed.
Otherwise, your vehicle may be damaged
and/or vehicle handling and performance may
be adversely affected.
Tire chains must be installed only on the rear
wheels and not on the front wheels.

● For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
All-Wheel Drive (AWD) models CAUTION● Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
Failure to do so may result in a circumference
difference between tires on the front and
rear axles which will cause excessive tire
wear and may damage the transmission,
transfer case and differential gears.
● ONLY use spare tires specified for the AWD
model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with tires
of the same size, brand, construction and tread
pattern. The tire pressure and wheel alignment
should also be checked and corrected as nec-
essary. Contact an INFINITI retailer. Wheel balance Unbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can
get out of balance. Therefore, they should be
balanced as required.
Wheel balance service should be performed with
the wheels off the vehicle. Spin balancing the
wheels on the vehicle could lead to mechanical
damage.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
INFINITI Warranty Information Booklet.
Care of wheels See “CLEANING EXTERIOR” in the “7. Appear-
ance and care” section for details about care of
the wheels.
Spare tire (TEMPORARY USE ONLY
(T-type) spare tire) Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident. WARNING● The T-type spare tire should be used for
emergency use. It should be replaced with
the standard tire at the first opportunity to
avoid possible tire or differential damage.
● Drive carefully while the TEMPORARY USE
ONLY spare tire is installed. Avoid sharp
turns and abrupt braking while driving.
● Periodically check spare tire inflation pres-
sure. Always keep the pressure of the TEM-
PORARY USE ONLY spare tire at 60 psi (420
kPa, 4.2 bar). Always keep the pressure of
the full size spare tire (if so equipped) at the
recommended pressure for standard tires,
as indicated on the Tire and Loading Infor-
mation label. For Tire and Loading Informa-
tion label location, see “Tire and Loading
Information label” in the index of this
manual.
● With the TEMPORARY USE ONLY spare tire
installed do not drive your vehicle at speeds
faster than 50 MPH (80 km/h).
● When driving on roads covered with snow or
ice, the TEMPORARY USE ONLY spare tire
should be used on the front wheels and origi-
nal tire used on the rear wheels (drive
wheels). Use tire chains only on the two rear
original tires.
