NISSAN FRONTIER 2011 Owner´s Manual

The fluid level should be checked using the HOT
MAX range on the power steering fluid reservoir
at fluid temperatures of 122° - 176°F (50° -
80°C) or using the COLD MAX range on the
power steering fluid reservoir at fluid tempera-
tures of 32° - 86°F (0° - 30°C) .
If the fluid is at or below the MIN line, add Genu-
ine NISSAN PSF. Remove the cap and fill
through the opening.
CAUTION
●DO NOT OVERFILL.
● Recommended fluid is Genuine
NISSAN PSF or equivalent. For further brake and clutch fluid specification
information, refer to “Capacities and recom-
mended fuel/lubricants” in the “Technical and
consumer information” section of this manual.
WARNING
●
Use only new fluid from a sealed con-
tainer. Old, inferior or contaminated
fluid may damage the brake and clutch
(if so equipped) systems. The use of
improper fluids can damage the brake
and clutch system and affect the vehi-
cle’s stopping ability.
● Clean the filler cap before removing.
● Brake and clutch fluid is poisonous and
should be stored carefully in marked
containers out of reach of children.
CAUTION
Do not spill the fluid on any painted sur-
faces. This will damage the paint. If fluid is
spilled, immediately wash the surface
with water.

WINDSHIELD-WASHER FLUID
RESERVOIR
Fill the windshield-washer fluid reservoir periodi-
cally. Add windshield-washer fluid when the low
windshield-washer fluid warning light (if so
equipped) comes on.
To fill the windshield-washer fluid reservoir, lift
the cap off the reservoir and pour the windshield-
washer fluid into the reservoir opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a windshield
washer antifreeze. Follow the manufacturer’s in-
structions for the mixture ratio. Refill the reservoir more frequently when driving
conditions require an increased amount of
windshield-washer fluid.
Recommended fluid is Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Anti-
freeze or equivalent.
CAUTION
●
Do not substitute engine anti-freeze
coolant for windshield-washer solution.
This may result in damage to the paint.
● Do not fill the windshield-washer reser-
voir with washer fluid concentrates at
full strength. Some methyl alcohol
based washer fluid concentrates may
permanently stain the grille if spilled
while filling the windshield-washer
reservoir.
● Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid
into the windshield-washer reservoir.
Do not use the windshield-washer res-
ervoir to mix the washer fluid concen-
trate and water.

●Keep the battery surface clean and dry.
Clean the battery with a solution of baking
soda and water.
● Make certain the terminal connections are
clean and securely tightened.
● If the vehicle is not to be used for 30 days or
longer, disconnect the negative (-) battery
terminal cable to prevent discharge.
WARNING
● Do not expose the battery to flames, an
electrical spark or a cigarette. Hydro-
gen gas generated by the battery is ex-
plosive. Explosive gases can cause
blindness or injury. Do not allow battery
fluid to contact your skin, eyes, fabrics
or painted surfaces. Sulfuric acid can
cause blindness or injury. After touch-
ing a battery or battery cap, do not
touch or rub your eyes. Thoroughly
wash your hands. If the acid contacts
your eyes, skin or clothing, immediately
flush with water for at least 15 minutes
and seek medical attention. ●
Do not operate the vehicle if the fluid in
the battery is low. Low battery fluid can
cause a higher load on the battery
which can generate heat, reduce bat-
tery life, and in some cases lead to an
explosion.
● When working on or near a battery, al-
ways wear suitable eye protection and
remove all jewelry.
● Battery posts, terminals and related ac-
cessories contain lead and lead com-
pounds. Wash hands after handling.
● Keep battery out of the reach of
children.
● Do not tip the battery. Keep the vent
caps tight and the battery level. 1. Remove the vent caps with a screwdriver as
shown. Use a cloth to protect the battery
case.

2. Check the fluid level in each cell. If it isnecessary to add fluid, add only distilled
water to bring the level up to the bottom of
the filler opening. Do not overfill.Reinstall
the vent caps. Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
JUMP STARTING
If jump starting is necessary, see “Jump starting”
in the “In case of emergency” section of this
manual. If the engine does not start by jump
starting, the battery may have to be replaced.
Contact a NISSAN dealer.
CAUTION
●
Do not ground accessories directly to
the battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
● Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
Your vehicle is equipped with a variable voltage
control system. This system measures the
amount of electrical discharge from the battery
and controls voltage generated by the generator.

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 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 blades with clear water. If your wind-
shield is still not clear after cleaning the blades
and using the wiper, replace the blades.
CAUTION
Worn windshield wiper blades can dam-
age the windshield and impair driver
vision.
REPLACING
Replace the wiper blades if they are worn.1. Lift the wiper arm away from the windshield.
2Push the release tab, then move the wiper
blade down the wiper arm to remove.
3Remove the wiper blade.
4. Insert the new wiper blade onto the wiper arm until it clicks into place.
5. Rotate wiper blade so the dimple is in the groove. 6. Return the wiper to its original position and
release it until it has made contact with the
windshield.
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 arms may be dam-
aged from wind pressure.

If you wax the surface of the hood, be careful not
to let wax get into the windshield washer nozzle
A. This may cause clogging or improper wind-
shield washer operation. If wax gets into the
nozzle, remove it with a needle or small pin
B. If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-adjust
every time the brake pedal is applied.
WARNING
See a NISSAN dealer for a brake system
check if the brake pedal height does not
return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have audible
wear indicators. When a brake pad requires re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal and does not affect the
function or performance of the brake system. Proper brake inspection intervals should
be followed.
For more information regarding
brake inspections, see the appropriate mainte-
nance schedule information in the “NISSAN Ser-
vice and Maintenance Guide”.
