brake INFINITI G 2010 Workshop Manual

●The pre-pressure function ceases when the
following conditions are met:
a) When the driver depresses the accelera- tor pedal or the brake pedal.
b) If the driver does not operate the accel- erator or brake pedal within approxi-
mately 1 second.
●The sensor will not detect:
a) Pedestrians or objects in the roadway
b) Oncoming vehicles in the same lane
c) Motorcycles traveling offset in the travel lane as illustrated
WARNING
●This system is only an aid to assist braking
operation and is not a collision warning or
avoidance device. It is the driver’s responsi-
bility to stay alert, drive safely and be in
control of the vehicle at all times. ●
As there is a performance limit to the Pre-
view Function, never rely solely on this sys-
tem. This system does not correct careless
inattentive or absent-minded driving, or
overcome poor visibility in rain, fog, or other
bad weather. Reduce vehicle speed by de-
pressing the brake pedal, in order to main-
tain a safe distance between vehicles.
● The system may not detect the vehicle in
front of you in certain road or weather condi-
tions. The Preview Function may not operate
properly under the following conditions. The
vehicle is still driveable under normal condi-
tions and the Brake Assist will operate.
– When rain, snow or dirt adhere to the sys- tem sensor
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– Winding or hilly roads may cause the sen- sor to temporarily not detect a vehicle in
the same lane or may detect objects or
vehicles in other lanes.
– Vehicle position in the lane may cause the sensor to temporarily not detect a vehicle
in the same lane or may detect objects or
vehicles in other lanes.

●When the Preview Function operates, the
brake pedal may move slightly and may
make a small noise. This is not a system
malfunction.
Warning light and display
When the Preview Function is not operating
properly, a chime sounds and the system warn-
ing light (orange) will come on.
Action to take :
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine and resume driving.
If the indicator stays on, it may indicate that the
Preview Function is malfunctioning (the brake is
operative). Although the Vehicle is still drive-
able under normal conditions, have the vehicle
checked at an INFINITI retailer.
How to handle the sensor
The sensor for the Preview Function is common
with Intelligent Cruise Control and is located
below the front bumper.
To keep the Preview Function operating prop-
erly, be sure to observe the following:
● Always keep the sensor clean. Wipe with a
soft cloth carefully so as not to damage the
sensor.
● Do not strike or damage the areas around
the sensor. Do not touch or remove the
screw located on the sensor. Doing so could
cause failure or malfunction. If the sensor is
damaged due to an accident, contact an
INFINITI retailer.
● Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion.

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.

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 reser-
voir 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 accel-
erating or downshifting 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 pavement.
● Allow greater following distances on slip-
pery roads.
● Watch for slippery spots (glare ice). These
may appear on an otherwise clear road in
shaded areas. If a patch of ice is seen ahead,
brake before reaching it. Try not to brake
while on the ice, and avoid any sudden steer-
ing maneuvers.
● Do not use the cruise control on slippery
roads.
● Snow can trap dangerous exhaust gases un-
der your vehicle. Keep snow clear of the ex-
haust pipe and from around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist in cold
temperature starting.
The engine block heater should be used when
the outside temperature is 20°F (7°C) or
lower.
To use the engine block heater
1. Turn the engine off.
2. Open the hood and unwrap the engine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded
110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least2-4hours, depending on
outside temperatures, to properly warm
the engine coolant. Use an appropriate
timer to turn the engine block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.

●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.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below.
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the selector lever to
the P (Park) position (Automatic transmis-
sion models). Move the shift lever to the R
(Reverse) gear (Manual transmission
models).
4. Turn off the engine.
5. Raise the hood to warn other traffic, and to signal professional road assistance
personnel that you need assistance. 6. Have all passengers get out of the vehicle
and stand in a safe place, away from
traffic and clear of the vehicle.
WARNING
●Make sure the parking brake is securely ap-
plied and the manual transmission is shifted
into R (Reverse), or the automatic transmis-
sion into P (Park).
● Never change tires when the vehicle is on a
slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for professional
road assistance.
Blocking wheels
Place suitable blocks1at both the front and
back of the wheel diagonally opposite the flat
tire to prevent the vehicle from moving when it
is jacked up.
WARNING
Be sure to block the wheel as the vehicle may
move and result in personal injury.

Installing the spare tire
The T-type spare tire is designed for emergency
use. (See specific instructions under the head-
ing “WHEELS AND TIRES” in the “8. Maintenance
and do-it-yourself” section.)
1. Clean any mud or dirt from the surfacebetween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
Models equipped with different sized tires in
the front and rear:
When replacing a front tire, make sure that
the hole in the spare tire wheel is aligned
with the pin on the brake rotor.
3. With the wheel nut wrench, tighten wheelnuts alternately and evenly in the se-
quence as illustrated (
1,2,3,4,5)
until they are tight.
4. Lower the vehicle slowly until the tire touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts se-
curely in the sequence as illustrated.
Lower the vehicle completely.
WARNING
●Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become
loose or come off. This could cause an
accident.
● Do not use oil or grease on the wheel studs or
nuts. This could cause the nuts to become
loose.
● Retighten the wheel nuts when the vehicle
has been driven for 600 miles (1,000 km)
(also in cases of a flat tire, etc.).
● As soon as possible, tighten the wheel nuts
to the specified torque with a torque wrench. Wheel nut tightening torque:
80 ft-lb (108 N·m)
The wheel nuts must be kept tightened to speci-
fication at all times. It is recommended that
wheel nuts be tightened to specifications at
each lubrication interval.
● Adjust tire pressure to the COLD pressure.
COLD pressure:
After the vehicle has been parked for three
hours or more or driven less than 1 mile (1.6
km).
COLD tire pressures are shown on the Tire
and Loading Information label affixed to the
driver side center pillar.SCE0661

CAUTION
●Do not continue to drive if your vehicle over-
heats. Doing so could cause engine damage
or a vehicle fire.
● To avoid the danger of being scalded, never
remove the radiator cap while the engine is
still hot. When the radiator cap is removed,
pressurized hot water will spurt out, possi-
bly causing serious injury.
● Do not open the hood if steam is coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading), or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply the parking brake and move the selector
lever to the P (Park) position (Automatic
transmission models). Move the shift lever
to the N (Neutral) position (Manual trans-
mission models).
Do not stop the engine.
2. Turn off the climate control. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 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 radia-
tor before opening the hood. (If steam or
coolant is escaping, turn off the engine.)
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. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leak-
ing or the cooling fan does not run, stop
the engine.
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 thecoolant level in the reservoir tank with the
engine running. Add coolant to the reser-
voir tank if necessary. Have your vehicle
repaired at the nearest INFINITI retailer.
