2011 INFINITI QX wiper blades

The rain sensor sensitivity level can be adjusted
by turning the knob toward the front
2(High)
or toward the rear
3(Low).
● High — High sensitive operation
● Low — Low sensitive operation
To turn the rain-sensing auto wiper system off,
push up the lever to the OFF position, or pull
down the lever to the LO or HI position.
CAUTION
Do not touch the rain sensor and around it when
the wiper switch is in the AUTO position and the
ignition switch is in the ON position. The wipers
may operate unexpectedly and cause to an in-
jury or a wiper damage.
● The rain-sensing auto wipers are intended for
use during rain. If the switch is left in the
AUTO position, the wipers may operate unex-
pectedly when dirt, fingerprints, oil film or
insects are stuck on or around the sensor.
The wipers may also operate when exhaust
gas or moisture affect the rain sensor.
● The rain-sensing auto wipers may not oper-
ate if rain does not hit the rain sensor even if
it is raining. ●
When the windshield glass is coated with
water repellent, the speed of the rain-
sensing auto wipers may be higher even
though the amount of the rainfall is small.
● Be sure to turn off the rain-sensing auto wiper
system when you use a car wash.
● Using genuine wiper blades is recommended
for proper operation of the rain-sensing auto
wiper system. (See “WINDSHIELD WIPER
BLADES” in the “8. Maintenance and do-it-
yourself” section for wiper blade replace-
ment.)
WARNING
In freezing temperatures the washer solution
may freeze on the rear window glass and ob-
scure your vision. Warm the rear window with
the defroster before you wash the rear window.
CAUTION
● Do not operate the washer continuously for
more than 30 seconds.
● Do not operate the washer if the reservoir
tank is empty.
● Do not fill the window washer reservoir tank
with washer fluid concentrates at full
strength. Some methyl alcohol based
washer fluid concentrates may permanently
stain the grille if spilled while filling the win-
dow washer reservoir tank.
● Pre-mix washer fluid concentrates with wa-
ter to the manufacturer’s recommended lev-
els before pouring the fluid into the window
washer reservoir tank. Do not use the win-
dow washer reservoir tank to mix the washer
fluid concentrate and water.

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 four-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.

When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking the
tires, make sure no wheel nuts are missing, and
check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires should be rotated every
7,500 miles (12,000 km).
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If nec-
essary, adjust the pressure in all tires, includ-
ing the spare, to the pressure specified. Check
carefully for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS) trans-
mitter components: Replace the TPMS transmit-
ter grommet seal, valve core and cap when the
tires are replaced due to wear or age.
Tire, wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment. If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
INFINITI Warranty Information Booklet.
Windshield:
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.
Accelerator pedal: Check the pedal for smooth
operation and make sure the pedal does not
catch or require uneven effort. Keep the floor
mat away from the pedal.
Automatic transmission P (Park) mechanism: On
a fairly steep hill, check that your vehicle is held
securely with the selector lever in the P (Park)
position without applying any brakes. Brake pedal:
Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down
further than normal, the pedal feels spongy or
the vehicle seems to take longer to stop, see an
INFINITI retailer immediately. Keep the floor mat
away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake opera-
tion regularly. The vehicle should be securely
held on a fairly steep hill with only the parking
brake applied. If the parking brake needs ad-
justed, see an INFINITI retailer.
Seat belts: Check that all parts of the seat belt
system (for example, buckles, anchors, adjuster
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
restraints/headrests move up and down
smoothly and that the locks (if so equipped)
hold securely in all latched positions.
Steering wheel: Check for changes in the steer-
ing conditions, such as excessive free play,
hard steering or strange noises.
Maintenance and do-it-yourself8-3

CLEANING
If your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your wind-
shield is clean if beads do not form when
rinsing with clear water.
Clean each blade by wiping it with a cloth
soaked in a washer solution or a mild deter-
gent. Then rinse the blade with clear water. If
your windshield is still not clear after cleaning
the blades and using the wiper, replace the
blades.
Worn windshield wiper blades can damage the
windshield and impair driver vision.
REPLACING
Replace the wiper blades if they are worn.
1. Pull the wiper arm.
2. Push the release tab
A, and then move
the wiper blade down the wiper arm
1
while pushing the release tab to remove.
3. Insert the new wiper blade onto the wiper arm until a click sounds.
4. Rotate the wiper blade so the dimple is in the groove.
CAUTION
●After wiper blade replacement, return the
wiper arm to its original position;
otherwise it may be damaged when the hood
is opened.
● Make sure the wiper blades contact the
glass; otherwise the arm may be damaged
from wind pressure.

Be careful not to clog the washer nozzleA.
This may cause improper windshield washer
operation. If the nozzle is clogged, remove any
objects with a needle or small pin
B.Be
careful not to damage the nozzle. Contact an INFINITI retailer if checking or re-
placement is required.
If the brakes do not operate properly, have the
brakes checked by an INFINITI retailer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
WARNING
See an INFINITI retailer for a brake system
check if the brake pedal height does not return
to normal.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear warn-
ings. When a brake pad requires replacement, it
will make a high pitched scraping sound when
the vehicle is in motion. This scraping sound
will first occur only when the brake pedal is
depressed. After more wear of the brake pad,
the sound will always be heard even if the brake
pedal is not depressed. Have the brakes
checked as soon as possible if the wear warn-
ing sound is heard.
