2019 INFINITI Q50 wiper blades

2-34Instruments and controls
Pulling up the wiper arm:
The wiper arm should be in the up position
when replacing the windshield wiper blades.
To replace the windshield wiper blades,
follow the procedure below:
1. When the ignition switch is ON or within60 seconds after placing the ignition
switch from the ON to OFF position,
place the windshield wiper and washer
lever into the OFF position.
2. Rapidly lift the lever
upwards twice
within 0.5 seconds. This action will cause
the wipers to automatically take the
service position.
To return the wiper arm, place the wiper arm
in the down position and operate the wiper
switch once.
CAUTION
Do not operate the windshield wiper
while the wiper arm is pulled up. The
wiper arm may be damaged.
Wiper drip wipe system:
The wiper will also operate once about 3
seconds after the washer and wiper are
operated. This operation is to wipe washer
fluid that has dripped on the windshield.

RAIN-SENSING AUTO WIPER
SYSTEM
The rain-sensing auto wiper system can
automatically turn on the wipers and adjust
the wiper speed depending on the rainfall
and the vehicle speed by using the rain
sensor located on the upper part of the
windshield.
To set the rain-sensing auto wiper system,
push the lever down to the AUTO position
. The wiper will sweep once while the
ignition switch is in the ON position.
The rain sensor sensitivity level can be
adjusted by turning the knob toward
(High) or toward(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 injury or
may damage a wiper.
. The rain-sensing auto wipers are in-
tended for use during rain. If the switch
is left in the AUTO position, the wipers
may operate unexpectedly 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
operate 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 recom-
mended for proper operation of the
rain-sensing auto wiper system. (See
“Windshield wiper blades” (P.8-22) for
wiper blade replacement.)

To defog/defrost the rear window glass and
outside mirrors, start the engine and push
the switch
on. The indicator lightwill
come on. Push the switch again to turn the
defroster off.
It will automatically turn off in approxi-
mately 15 minutes.
If the engine is started using the remote start
function (if so equipped) when the outside
air temperature, the interior temperature
and the engine coolant temperature are
low, the rear window glass and outside
mirror defroster may turn on automatically.
For additional information about the remote
engine start function, see “Remote engine
start” (P.3-20).
CAUTION
When cleaning the inner side of the rear
window, be careful not to scratch or
damage the rear window defroster.

If you install snow tires, they must also be
the same size, brand, construction and tread
pattern 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
reservoir 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 accelerating or down-
shifting 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 pave-
ment.
. Allow greater following distances on
slippery 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 under your vehicle. Keep snow
clear of the exhaust 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 least 2 - 4 hours, 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.

CLEANING
If your windshield is not clear after using the
windshield washer or if a wiper blade
chatters when running, wax or other materi-
al may be on the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield 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
detergent. 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.
When a washer nozzle is clogged
It is recommended you see an INFINITI
retailer if a washer nozzle is clogged or any
malfunction occurs. Do not attempt to clean
the nozzle using a needle or a pin. Doing so
may damage the nozzle.

REPLACING
Replace the wiper blades if they are worn.
Before replacing the wiper blades, the wiper
should be in the fully up position to avoid
scratching the engine hood or damaging the
wiper arm. To pull up the wiper arm, see
“Wiper and washer switch” (P.2-33).
1. Pull the wiper arm.
2. Push the release tab
, and then move
the wiper blade down the wiper arm
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, re-
turn 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.
WINDSHIELD WIPER BLADES

other corrosive materials, check lubrication
frequently.
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
5,000 miles (8,000 km). If your vehicle is
equipped with different sized tires in the
front and rear, tires cannot be rotated.
Tires*: Check the pressure with a gauge
often and always prior to long distance trips.
If necessary, adjust the pressure in all tires,
including the spare, to the pressure speci-
fied. Check carefully for damage, cuts or
excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and
cap when the tires are replaced due to wear
or age.
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 scheduled 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) mechan-
ism: On a fairly steep hill, check that your
vehicle is held securely with the shift lever in
the P (Park) position without applying any
brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes down further than normal, the pedal feels
spongy or the vehicle seems to take longer to
stop, have your vehicle checked immediately.
It is recommended you visit an INFINITI
retailer for this service. 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
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, it is recommended you
visit an INFINITI retailer for this service.
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 move up and down
smoothly and that the locks (if so equipped)
hold securely in all latched positions.
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 webbing for cuts, fraying,
wear or damage.
Steering wheel: Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
