cruise control INFINITI EX 2011 Owner's Guide

Sensor maintenance
How to handle the sensor :
The sensor for the DCA system is common with
Intelligent Cruise Control and is located below
the front bumper.
To handle the sensor, see “INTELLIGENT CRUISE
CONTROL (ICC) SYSTEM (FULL SPEED RANGE)”
earlier in this section.The Forward Collision Warning (FCW) system
will warn the driver by a warning light and
chime when your vehicle is getting close to the
vehicle ahead in the traveling lane.
The FCW system will function when your vehicle
is driven at speeds of approximately 10 MPH
(15 km/h) and above.

FCW system operation
The FCW system will function at speeds of
approximately 10 MPH (15 km/h) and above,
when the system turns on.
The FCW system has an automatic setting mode
and a manual setting mode to turn the system
on. The setting mode can be changed. In the
automatic setting mode, the FCW system is
automatically turned on when the ignition
switch is pushed to the ON position. When the
FCW system is on, the warning systems ON
indicator light
1on the warning systems
switch illuminates. To cancel the FCW system,
push the warning systems switch. The warning systems ON indicator light will turn off. To turn
on the system, push the warning systems
switch again.
When the warning systems switch is pushed,
the LDW BSW system will also turn on or off
simultaneously. See “LANE DEPARTURE WARN-
ING (LDW) SYSTEM” earlier in this section and
“BLIND SPOT WARNING (BSW) SYSTEM” earlier
in this section.
In the manual setting mode, you need to push
the warning systems switch to turn on the
system after the ignition switch is pushed to the
ON position.
The setting mode can be changed using the
warning systems switch. To change the setting
mode, push and hold the warning systems
switch for more than 4 seconds when the
warning systems ON indicator is off. When the
mode is changed, a chime sounds and the lane
departure warning light (orange) flashes.
For the sensor maintenance, see “INTELLIGENT
CRUISE CONTROL (ICC) SYSTEM (FULL SPEED
RANGE)” earlier in this section.
The Intelligent Brake Assist (IBA) system warns
the driver by a warning light and chime when
there is a risk of a collision with the vehicle
ahead in the traveling lane and the driver must
take avoidance action immediately. The system
helps reduce the rear-end collision speed by
applying the brakes when the system judges
that the collision cannot be prevented.
The IBA system will function when your vehicle
is driven at speeds of approximately 10 MPH (15
km/h) and above, and when your vehicle is
driven at speeds approximately 10 MPH (15
km/h) faster than the vehicle ahead.

The IBA system will remain in the last ON or OFF
state it was left in until it is manually changed
by pressing the IBA OFF switch.
Illumination of the IBA OFF indicator light with-
out the warning chime sound is an indication
that the IBA system is temporarily unavailable.
It will occur under the following conditions:
– When driving into a strong light (for example,sunlight)
The IBA OFF indicator light will turn off when the
system returns to its normal operating condi-
tions.
For the sensor maintenance, see “INTELLIGENT
CRUISE CONTROL (ICC) SYSTEM (FULL SPEED
RANGE)” earlier in this section.CAUTION
During the first 1,200 miles (2,000 km), follow
these recommendations to obtain maximum
engine performance and ensure the future reli-
ability and economy of your new vehicle.
Failure to follow these recommendations may
result in shortened engine life and reduced en-
gine performance.
● Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible. ●
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
● Avoid unnecessary stopping and braking.
Keep a safe distance behind other vehicles.
● Select a gear range suitable to road condi-
tions.
● Avoid unnecessary prolonged engine idling.
● Keep your engine tuned up.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated at the correct pres-
sure. Improper tire pressure will increase
wear and waste fuel.
● Make sure the front wheels are properly
aligned. Improper alignment will cause pre-
mature tire wear and lower fuel economy.
● Climate control operation lowers fuel
economy. Use the air conditioner only when
necessary.
● When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
BREAK-IN SCHEDULE INCREASING FUEL ECONOMY
Starting and driving5-73

WARNING
●While driving on a slippery surface, be care-
ful when braking, accelerating or downshift-
ing. Abrupt braking or accelerating could
cause the wheels to skid and result in an
accident.
● If the engine is not running or is turned off
while driving, the power assist for the
brakes will not work. Braking will be harder.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force than
a conventional brake booster even with light
pedal force.
WARNING
The Brake Assist is only an aid to assist braking
operation and is not a collision warning or
avoidance device. It is the driver’s responsibil-
ity to stay alert, drive safely and be in control of
the vehicle at all times.
PREVIEW FUNCTION (Intelligent Cruise
Control system equipped models)
When the Preview Function identifies the need
to apply emergency braking by sensing a ve-
hicle ahead in the same lane and the distance
and relative speed from it, it applies the brake
pre-pressure before the driver depresses the
brake pedal and helps improve brake response
by reducing pedal free play.
● This system will not operate when the ve-
hicle is moving at approximately 20 MPH (32
km/h) or less.
● The pre-pressure function ceases when the
following conditions are met:
a) When the driver depresses the accel- erator pedal or the brake pedal.
b) If the driver does not operate the ac- celerator or brake pedal within ap-
proximately 1 second.
BRAKE ASSIST
5-78Starting and driving

Warning light and display
When the Preview Function is not operating
properly, the buzzer sounds and the system
warning 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 speci-
fied on the Tire and Loading Information
label. See “TIRE AND LOADING INFORMA-
TION LABEL” in the “9. Technical and con-
sumer information” section of this
manual.

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.
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.
