brake NISSAN FRONTIER 2023 Repair Manual

Follow these easy-to-use Fuel Efficient
Driving Tips to help you achieve the most
fuel economy from your vehicle.
1.Use Smooth Accelerator and Brake
Pedal Application
• Avoid rapid starts and stops.
• Use smooth, gentle accelerator and brake application whenever possible.
• Maintain constant speed while com- muting and coast whenever possible.
2. Maintain Constant Speed
• Look ahead to try and anticipate and minimize stops.
• Synchronizing your speed with traffic lights allows you to reduce your num-
ber of stops.
• Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency.
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
• Below 40 mph (64 km/h), it is more efficient to open windows to cool the
vehicle due to reduced engine load.
• Above 40 mph (64 km/h), it is more efficient to use A/C to cool the vehicle
due to increased aerodynamic drag. • Recirculating the cool air in the cabin
when the A/C is on reduces cooling
load.
4. Drive at Economical Speeds and
Distances
• Observing the speed limit and not ex- ceeding 60 mph (97 km/h) (where le-
gally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
• Maintaining a safe following distance behind other vehicles reduces unnec-
essary braking.
• Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes.
• Select a gear range suitable to road conditions.
5. Use Cruise Control
• Using cruise control during highway driving helps maintain a steady speed.
• Cruise control is particularly effective in providing fuel savings when driving
on flat terrains.
6. Plan for the Shortest Route
• Utilize a map or navigation system to determine the best route to save time. 7.
Avoid Idling
• Shutting off your engine when safe for stops exceeding 30–60 seconds saves
fuel and reduces emissions.
8. Buy an Automated Pass for Toll Roads
• Automated passes permit drivers to use special lanes to maintain cruising
speed through the toll and avoid stop-
ping and starting.
9. Winter Warm Up
• Limit idling time to minimize impact to fuel economy.
• Vehicles typically need no more than 30 seconds of idling at start-up to ef-
fectively circulate the engine oil before
driving.
• Your vehicle will reach its ideal operat- ing temperature more quickly while
driving versus idling.
10. Keeping your Vehicle Cool
• Park your vehicle in a covered parking area or in the shade whenever
possible.
• When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system.
FUEL EFFICIENT DRIVING TIPS
5-108Starting and driving

• Keep your engine tuned up.
• Follow the recommended scheduledmaintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire
wear and lowers fuel economy.
• Keep the wheels in correct alignment. Im- proper alignment increases tire wear and
lowers fuel economy.
• For vehicles equipped with
, use 4H
or 4L position only when necessary.
4-Wheel Drive operation lowers fuel
economy.
• Use the recommended viscosity engine oil. For additional information, see “Engine
oil and oil filter recommendations”
(P. 10-7).
WARNING
• For 4WD equipped vehicles, do not
attempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or per-
sonal injury.
• Do not attempt to test a 4WD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamom-
eters used by some states for emis-
sions testing), or similar equipment
even if the other two wheels are
raised off the ground. Make sure you
inform test facility personnel that
your vehicle is equipped with 4WD
before it is placed on a dynamom-
eter. Using the wrong test equipment
may result in drivetrain damage or
unexpected vehicle movement
which could result in serious vehicle
damage or personal injury.CAUTION
• Do not drive the vehicle in the 4H or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces in
4H or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD vehicle information dis-
play warning message turns on
when you are driving on dry hard sur-
face roads:
– In the 4H position, shif t the 4WD
shif t switch to 2WD.
– In the 4LO position, stop the ve-
hicle, move the shif t lever to the N
(Neutral) position with the brake
pedal depressed, and shif t the
4WD shif t switch to 2WD.
• If the vehicle information display
warning message is still on af ter the
above operation, have your vehicle
checked as soon as possible. It is rec-
ommended that you visit a NISSAN
dealer for this service.

*1: Before moving the shif t lever from N
(Neutral), wait until the 4LO indicator stays
on steady. This indicates that the 4WD shif t
procedure is completed and the transfer
gear is correctly set in the 4LO position. If
the vehicle is shif ted into gear before the
indicator is on steady, the transfer gear
may grind, not engage correctly or stay in
the N (Neutral) position.
- If the 4WD vehicle information display
warning message illuminates, perform the
following procedure to return the transfer
case to correct operating condition.
1. Turn off the engine by placing the ignition
switch in the OFF position.
2. Start the engine.
- Check that the 4WD vehicle information
display warning message turns off. If the
warning message in the vehicle informa-
tion display stays on, have the system
checked. It is recommended that you visit a
NISSAN dealer for this service.
3. Apply the parking brake, depress the
brake pedal and move the shif t lever to the
N (Neutral) position.
4. With the brake pedal depressed, move
the 4WD shif t switch to the desired mode.- Be sure to wait until the transfer gear
change completes before shif ting the shif t
lever from the N (Neutral) position.
*2: While changing in and out of 4LO, the
ignition switch must be in the ON position
and the vehicle's engine must be running
for a shif t to take place and for the 4WD
shif t and 4LO position indicators to be op-
erable. Otherwise, the shif t will not take
place and no indicators will be on or
flashing.
*3: Make sure the transfer 4LO position in-
dicator turns on when you shif t the 4WD
shif t switch to 4LO. The
indicator light
will also turn on when 4LO is selected. For
additional information, see “Vehicle Dy-
namic Control (VDC) system” (P. 5-121).
When the 4LO position is selected, the VDC
system is disabled and the VDC off indica-
tor light illuminates, see “Vehicle Dynamic
Control (VDC) OFF indicator light”(P. 2-20).
The transfer case 4WD shif t switch is used
to select either 2WD or 4WD depending on
the driving conditions. There are three
types of drive modes available, 2WD, 4H and
4LO. The 4WD shif t switch electronically controls
the transfer case operation. Rotate the
switch to move between each mode, 2WD,
4H and 4LO.
To change into or out of 4LO, the vehicle
MUST be stationary, move the shif t lever
to N (Neutral), and depress the brake
pedal. The switch must be pushed and
turned to select 4LO.
WARNING
• When parking, apply the parking
brake before stopping the engine
and make sure that the 4WD shif t
indicator is on and the Automatic
Transmission Park (ATP) warning
light goes off. Otherwise, the vehicle
could unexpectedly move even if the
A/T is in the P (Park) position.
• The 4LO indicator must stop blinking
and remain illuminated or turn off
before shif ting the transmission
into gear. If the shif t lever is shif ted
from the N (Neutral) position to any
other gear when the 4LO indicator is
blinking, the vehicle may move
unexpectedly.
Starting and driving5-111

CAUTION
• Never shif t the 4WD shif t switch be-
tween 4LO and 4H while driving.
• The 4H position provides greater
traction. Avoid excessive speed, as it
will cause increased fuel consump-
tion and higher oil temperatures, and
could damage drivetrain compo-
nents. Speeds over 62 mph (100
km/h) in 4H is not recommended.
• The 4LO position provides maximum
power and traction. Avoid raising ve-
hicle speed excessively, as the maxi-
mum speed is approximately 31 mph
(50 km/h).
• When driving straight, shif t the 4WD
shif t switch to the 2WD or 4H posi-
tion. Do not move the 4WD shif t
switch when making a turn or
reversing.
• Do not shif t the 4WD shif t switch (be-
tween 2WD and 4H) while driving on
steep downhill grades. Use the en-
gine brake and low A/T gears (M1 or
M2) for engine braking.
• Do not operate the 4WD shif t switch
(between 2WD and 4H) with the rear
wheels spinning. •
Do not drive on dry hard surface
roads in the 4H or 4LO position. Driv-
ing on dry hard surfaces in 4H or 4LO
may cause unnecessary noise and
tire wear. NISSAN recommends driv-
ing in the 2WD position under these
conditions.
• The 4WD transfer case may not be
shif ted between 4H and 4LO at low
ambient temperatures and the
transfer 4LO position indicator may
blink even when the 4WD shif t switch
is shif ted. Af ter driving for a while
you can change the 4WD transfer
case between 4H and 4LO.
When driving on rough roads:
• Set the 4WD shif t switch to 4H or 4LO.
• Drive carefully according to the road sur- face conditions.
When the vehicle is stuck:
• Set the 4WD shif t switch to 4H or 4LO.
• Place stones or wooden blocks under the tires to free the vehicle.
• Use the Electronic locking rear differential (E-Lock) system (if so equipped). For addi-
tional information, see “Electronic locking
rear differential (E-Lock) system” (P. 5-115). • If it is difficult to free the vehicle, rock the
vehicle back and forth between reverse
and drive gears.
• If the vehicle is stuck deep in mud, place stones or wooden blocks under the tires.
Then try the recovery procedures above.
Tire chains may be effective.
CAUTION
• Do not spin the tires excessively. Tires
will sink deep into the mud, making it
difficult to free the vehicle.
• Avoid shif ting gears with the engine
running at high speeds as this may
cause malfunction.
5-112Starting and driving

4WD shif t switch operations
• Shif t the 4WD shif t switch to either the2WD, 4H or 4LO position, depending on
driving conditions.
• If the 4WD shif t switch is operated
while making a turn, accelerating or
decelerating or if the ignition switch is
placed in the OFF position while in the
4H or 4LO, you may feel a jolt. This is not
abnormal.
•
You may hear some noise as the system
shif ts or engages. This is not abnormal.
CAUTION
•
When driving straight, shif t the 4WD
shif t switch to the 2WD or 4H position.
Do not move the 4WD shif t switch
when making a turn or reversing.
•Do not shif t the 4WD shif t switch while
driving on steep downhill grades. Use
the engine brake and low automatic
transmission gears (M1 or M2) for en-
gine braking.
• Do not operate the 4WD shif t switch
with the rear wheels spinning.
• Before placing the 4WD shif t switch
in the 4H position from 2WD, ensure
the vehicle speed is less than 62 mph
(100 km/h). Failure to do so can dam-
age the 4WD system.
• Never shif t the 4WD shif t switch be-
tween 4LO and 4H while driving.
4WD shif t indicator
The 4WD shif t indicator is located in the
vehicle information display.
The indicator should turn off within one
second af ter placing the ignition switch in
the ON position.
While the engine is running, the 4WD shif t
indicator will illuminate the position se-
lected by the 4WD shif t switch.
• The 4WD shif t indicator may come on
while shif ting from one drive mode to
the other. When the shif ting is com-
pleted, the 4WD shif t indicator will stay
on.

CAUTION
If the 4WD shif t indicator indication
changes to 2WD when the 4WD shif t
switch is shif ted to the 4H position at
low ambient temperatures, the 2WD
mode may be being engaged due to
malfunctioning drive system. If the in-
dicator does not return to normal and
the 4WD vehicle information display

rotation is large
The 4WD warning message is located in
the meter. The 4WD warning message
comes on when the ignition switch is
placed in the ON position. It turns off soon
af ter the engine is started. If any malfunc-
tion occurs in the 4WD system when the
ignition switch is ON, the warning message
will either remain illuminated or blink. If the
4WD warning message comes on, the 4WD
shif t indicator goes out. A large difference
between the diameters of front and rear
wheels will make the warning message
blink slowly (about once per two seconds).
Shif t the 4WD shif t switch into 2WD and do
not drive fast.
CAUTION
• If the warning message comes on
during operation or rapidly af ter
stopping the vehicle for a while, have
your vehicle checked as soon as pos-
sible. It is recommended that you
visit a NISSAN dealer for this service.
• Shif ting between 4H and 4LO is not
recommended when the 4WD
warning message turns on. •
When the warning message comes
on, the 2WD mode may be engaged
even if the 4WD shif t switch is in 4H.
Be especially careful when driving. If
corresponding parts are malfunc-
tioning, the 4WD mode will not be en-
gaged even if the 4WD shif t switch is
shif ted.
• Do not drive the vehicle in the 4H or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces in
4H or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD warning message turns on
when you are driving on dry hard sur-
face roads:
– In the 4H position, shif t the 4WD
shif t switch to 2WD.
– In the 4LO position, stop the ve-
hicle, move the automatic trans-
mission shif t lever to the N (Neu-
tral) position with the brake pedal
depressed, and shif t the 4WD shif t
switch to 2WD.
5-114Starting and driving

CAUTION
• Af ter using the E-Lock system, turn
the switch OFF to prevent possible
damage to driveline components
from extended use.
•
Do not drive the vehicle at speeds
faster than 12 mph (20 km/h) when the
system is engaged. Doing so could
damage drivetrain components.
•Do not turn on the E-Lock system
while the tires are spinning. Doing so
could damage drivetrain components.
WARNING
• Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire. •
Safe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park).
Failure to do so could cause the ve-
hicle to move unexpectedly or roll
away and result in an accident. Make
sure the shif t lever has been pushed
as far forward as it can go and cannot
be moved without depressing the
foot brake pedal.
• Never leave the engine running while
the vehicle is unattended.

PARKING/PARKING ON HILLS
5-116Starting and driving

•Do not leave children unattended in-
side the vehicle. They could unknow-
ingly activate switches or controls or
make the vehicle move. Unattended
children could become involved in
serious accidents.
• To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
1. Firmly apply the parking brake.
2. Move the shif t lever to the P (Park) position.
3. To help prevent the vehicle from rolling into traffic when parked on an incline, it
is a good practice to turn the wheels as
illustrated.
• HEADED DOWNHILL WITH CURB
OA:
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb. • HEADED UPHILL WITH CURB
OB:
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
• HEADED UPHILL OR DOWNHILL, NO CURB
OC:
Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.
4. Place the ignition switch in the LOCK position. The power assisted steering uses a hy-
draulic pump, driven by the engine, to as-
sist steering.
If the engine stops or the drive belt breaks,
you will still have control of the vehicle.
However, much greater steering effort is
needed, especially in sharp turns and at
low speeds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
POWER STEERING
Starting and driving5-117

The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKE PRECAUTIONS
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear and to prevent
the brakes from overheating, reduce speed
and downshif t to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.
WARNING
• While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshif ting. 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.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, your braking distance will be lon-
ger and the vehicle may pull to one side
during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake
pedal to heat up the brakes. Do this until
the brakes return to normal. Avoid driving
the vehicle at high speeds until the brakes
function correctly.
Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking
performance.
This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
• The ABS is a sophisticated device, but
it cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces 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 ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
• Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.
