steering wheel INFINITI G 2010 Workshop Manual

SONAR SYSTEM OFF SWITCH
The sonar system OFF switch on the instrument
panel allows the driver to turn the sonar system
on and off. To turn the sonar system on and off,
the ignition switch must be in the “ON” posi-
tion. The indicator light
1on the switch will
illuminate when the system is turned off. If the
indicator light flashes when the sonar system is
not turned off, it may indicate a malfunction in
the sonar system.
WARNING
If the engine is not running or is turned off while
driving, the power assist for the steering will
not work. Steering will be harder to operate.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns and at low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. How-
ever, greater foot pressure on the brake pedal
will be required to stop the vehicle and the
stopping distance will be longer.
When the brake pedal is depressed slowly and
firmly, you may hear a clicking noise and feel a
slight pulsation. This is normal and indicates
that the Brake Assist System is operating.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.

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.
WARNING
Do 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.

The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and
vehicle motion. Under certain driving condi-
tions, 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 output
to reduce drive wheel slip based on vehicle
speed (traction control function).
● Controls brake pressure at individual wheels
and engine output to help the driver main-
tain control of the vehicle in the following
conditions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing 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
indicator 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 “Slip indicator light” in the “2. Instruments
and controls” section and “Vehicle Dynamic
Control (VDC) off indicator light” in the “2.
Instruments and controls” section.
If a malfunction occurs in the system, the
andindicator lights come on in the
instrument panel. The VDC system automati-
cally turns off when these indicator lights are
on.
The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator 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
indicator
flashes if this occurs. All other VDC functions
are off and the
indicator 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.
The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in
reverse at a slow speed. When the self-test
occurs, you may hear a “clunk” noise and/or
feel a pulsation in the brake pedal. This is
normal and is not an indication of a malfunc-
tion.
WARNING
●
The VDC system is designed to help the
driver maintain stability but does not pre-
vent accidents due to abrupt steering opera-
tion at high speeds or by careless or danger-
ous driving techniques. Reduce vehicle
speed and be especially careful when driving
and cornering on slippery surfaces and al-
ways drive carefully.

●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
andindicator
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
andindicator lights may
illuminate.
● If engine control related parts are not
INFINITI recommended or are extremely de-
teriorated, both the
andindica-
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 bothandindicator 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 bothand
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
andindicator 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.

●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.
WARNING
The 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.

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 switch3 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.

the steering wheel will lock and cannot be
turned. Supply power using jumper cables
before pushing the ignition switch and dis-
engaging the steering lock.
CAUTION
●Always connect positive (+) to positive (+)
and negative () to body ground (as illus-
trated) — not to the battery.
● Make sure the jumper cables do not touch
moving parts in the engine compartment and
that clamps do not contact any other metal.
5. Start the engine of the booster vehicleA
and let it run for a few minutes.
6. Keep the engine speed of the booster vehicle
Aat about 2,000 rpm, and start
the engine of the vehicle being jump
started

CAUTION
Do not keep the starter motor engaged for more
than 10 seconds. If the engine does not start
right away, push the ignition switch to the OFF
position and wait 10 seconds before trying
again.
7. After starting your engine, carefully dis- connect the negative cable and then the
positive cable (
4→3→2→1).
8. Replace the vent caps (if so equipped). Be sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
9. Put the battery cover on.
Do not attempt to start the engine by pushing.
CAUTION
● Automatic transmission models cannot be
push-started or tow-started. Attempting to
do so may cause transmission damage.
● Three way catalyst equipped models should
not be started by pushing since the three
way catalyst may be damaged.
● Never try to start the vehicle by towing it;
when the engine starts, the forward surge
could cause the vehicle to collide with the
tow vehicle.

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.

CAUTION
● Tow chains or cables must be attached only
to the vehicle recovery hooks or main struc-
tural members of the vehicle. Otherwise, the
vehicle body will be damaged.
● Do not use the vehicle tie downs to free a
vehicle stuck in sand, snow, mud, etc.
● Never tow a vehicle using the vehicle tie
downs or recovery hooks. ●
Always pull the cable straight out from the
front of the vehicle. Never pull on the vehicle
at an angle.
● Pulling devices should be routed so they do
not touch any part of the suspension, steer-
ing, brake or cooling systems.
● Pulling devices such as ropes or canvas
straps are not recommended for use in ve-
hicle towing or recovery.
Rocking a stuck vehicle
If your vehicle is stuck in sand, snow, mud, etc.,
use the following procedure:
1. Turn off the Vehicle Dynamic Control (VDC)
system.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and back- ward.
●Shift back and forth between R (reverse) and
D (drive) (automatic transmission models) or
1st (low) and R (reverse) (manual transmis-
sion models). ●
Apply the accelerator as little as possible to
maintain the rocking motion.
● Release the accelerator pedal before shifting
between R and D (automatic transmission
models) or 1st and R (manual transmission
models).
● Do not spin the tires above 35 MPH (55
km/h).
5. If the vehicle cannot be freed after a few tries, contact a professional towing ser-
vice to remove the vehicle.
