2021 INFINITI QX50 wheel

•Always use tires of the same type, size,
brand, construction (bias, bias-belted, or
radial), and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
• Be sure to check the brakes immediately
after driving in mud or water. For addi-
tional information, see “Brake precau-
tions” (P. 5-152).
• Avoid parking your vehicle on steep hills.
If you get out of the vehicle and it rolls
forward, backward or sideways, you
could be injured.
• Whenever you drive off-road through
sand, mud or water as deep as the wheel
hub, more frequent maintenance may be
required. For additional information, see
“Additional maintenance items for se-
vere operating conditions” (P. 9-7).INTELLIGENT ALL-WHEEL
DRIVE (AWD) DRIVING SAFETY
PRECAUTIONS (if so equipped)
WARNING
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
• Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
• This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
• For AWD equipped vehicles, do not at-
tempt to raise two wheels off the ground
and shift the transmission to any D
(Drive) or R (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 personal injury. •
Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing) or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong test
equipment may result in drivetrain dam-
age or unexpected vehicle movement
which could result in serious vehicle dam-
age or personal injury.
• When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
5-12Starting and driving

Manual shift mode
The transmission enters the manual shift
mode by moving the shift lever again to the D
(Drive) position when the vehicle is in the D
range.
You can select the manual shift range by
pulling the left side or right side paddle shifter
OAandOB. To cancel the manual shift mode,
move the shift lever to the D (Drive) position
again. The transmission returns to the auto-
matic drive mode.
When the shift lever is shifted from D (Drive)
to the manual shift mode with the vehicle stopped or while driving, the transmission
enters the manual shift mode. Shift ranges
can be selected manually. Shift ranges can
also be selected using the paddle shifters on
the steering wheel. When you pull the paddle
shifter while in the D (Drive) position, the
transmission will shift to the upper or lower
range temporarily. If the paddle shifters are
not used for about 5–10 seconds, the trans-
mission will automatically return to the D
(Drive) position. If you want to return to the D
(Drive) position manually, pull and hold either
paddle shifter for about 1.5 seconds.In the manual shift mode, the shift range is
displayed on the position indicator in the me-
ter. When moving the shift lever to the
manual shift mode, the position indicator dis-
plays 1 (1st) up to 8 (8th) depending on ve-
hicle speed.
Shift ranges up or down one by one as
follows:
1⇔
2⇔ 3⇔ 4⇔ 5⇔ 6⇔ 7⇔ 8
8 (8th)
Use this position for all normal forward driv-
ing at highway speeds.
7 (7th), 6 (6th) and 5 (5th)
Use this position when driving up long slopes,
or for engine braking when driving down long
slopes.
4 (4th), 3 (3rd) and 2 (2nd)
Use these positions for hill climbing or engine
braking on downhill grades.
1 (1st)
Use this position when climbing steep hills
slowly or when driving slowly, or for maxi-
mum engine braking on steep downhill
grades.

Starting and driving5-21

• Remember not to drive at high speeds forextended periods of time in lower than 8th
gear. This reduces fuel economy.
When shifting up
Use the + (up) side paddle shifter
OB. (Shifts to
higher range.)
When shifting down
Use the − (down) side paddle shifter
OA.
(Shifts to lower range.)
• The transmission will automatically down- shift the gears. (For example, if you select
the 3rd range, the transmission will shift
down between the 3rd and 1st gears.)
• Moving the shift lever rapidly to the same side twice will shift the ranges in
succession.
When canceling the manual shift mode
Move the shift lever to the D (Drive) position
to return the transmission to the normal driv-
ing mode.
• In the manual shift mode, the transmission
may not shift to the selected gear. This
helps maintain driving performance and
reduces the chance of vehicle damage or
loss of control. •
When this situation occurs, the Continu-
ously Variable Transmission (CVT) posi-
tion indicator will blink and the chime will
sound.
• In the manual shift mode, the transmission
may shift up automatically to a higher
range than selected if the engine speed is
too high. When the vehicle speed de-
creases, the transmission automatically
shifts down and shifts to 1st gear before
the vehicle comes to a stop.
• CVT operation is limited to automatic drive mode when CVT fluid temperature is ex-
tremely low even if manual shift mode is
selected. This is not a malfunction. When
CVT fluid warms up, manual mode can be
selected.
• When the CVT fluid temperature is high, the shift range may upshift in lower rpm
than usual. This is not a malfunction.
Accelerator downshift
— in D (Drive) position —
For passing or hill climbing, depress the ac-
celerator pedal to the floor. This shifts the
transmission down into a lower gear, de-
pending on the vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid tempera-
ture protection mode. If the fluid temperature
becomes too high (for example, when climb-
ing steep grades in high temperatures with
heavy loads, such as when towing a trailer),
engine power and, under some conditions,
vehicle speed will be decreased automatically
to reduce the chance of transmission dam-
age. Vehicle speed can be controlled with the
accelerator pedal, but the engine and vehicle
speed may be limited.
Fail-safe
When the fail-safe operation occurs, the
Continuously Variable Transmission will not
be shifted into the selected driving position.
If the vehicle is driven under extreme condi-
tions, such as excessive wheel spinning and
subsequent hard braking, the fail-safe sys-
tem may be activated. The Malfunction Indi-
cator Light (MIL) may come on to indicate
the fail-safe mode is activated. For addi-
tional information, see “Malfunction Indica-
tor Light (MIL)” (P. 2-15). This will occur
even if all electrical circuits are functioning
properly. In this case, place the ignition
switch in the OFF position and wait for 10
5-22Starting and driving

WARNING
• The electronic parking brake will not be
automatically applied when the engine is
stopped without using the ignition
switch (for example, by engine stalling).
Without the vehicle stationary, the elec-
tronic parking brake will not be auto-
matically applied even if the engine is
turned off with the ignition switch.
• Before leaving the vehicle, press the Park
button to place the vehicle in the P (Park)
position and check that the electronic
parking brake indicator light is illumi-
nated to confirm that the electronic
parking brake is applied. The electronic
parking brake indicator light will remain
on for a period of time after the driver’s
door is locked.
CAUTION
When parking in an area where the outside
temperature is below 32°F (0°C), the park-
ing brake, if applied, may freeze in place
and may be difficult to release.
For safe parking, it is recommended that
you place the shift lever in the P (Park)
position and securely block the wheels.
NOTE:
• If a malfunction occurs in the electronic parking brake system (for example, due to
battery discharge), it is recommended that
you visit an INFINITI retailer.
• If the shift lever is moved to the P (Park) position when the brake force is main-
tained by the automatic brake hold func-
tion, the electronic parking brake will ap-
ply automatically.
• If the driver’s seat belt is unfastened when the brake force is maintained by the auto-
matic brake hold function, the electronic
parking brake will apply automatically.
• If the ignition switch is placed in the OFF position when the brake force is main-
tained by the automatic brake hold func-
tion, the electronic parking brake will ap-
ply automatically.
• Under the following conditions, the elec- tronic parking brake will automatically be
applied and the brake force of the auto-
matic brake hold will be released:
– The braking force is applied by the auto- matic brake hold function for 3 minutes
or longer.
– The vehicle is placed in the “P” (Park) position.
– The driver’s seat belt is unfastened. – The ignition switch is placed in the
“OFF” position.
– The electronic parking brake is applied.
– If a malfunction occurs in the automatic brake hold function.
MANUAL OPERATION
The electronic parking brake will not be auto-
matically applied if the engine is stopped
without using the ignition switch (for ex-
ample, by engine stalling). In such a case, you
have to apply the parking brake manually.
To apply: Pull the switch up
O1. The indicator
light
OAwill illuminate.
To release: With the ignition switch in the ON
position, depress the brake pedal and push
the switch down
O2. The indicator lightOAwill turn off.
Before driving, check that the electronic
parking brake indicator light (red) (if so
equipped)
orgoes out. For addi-
tional information, see “Warning lights, indi-
cator lights and audible reminders” (P. 2-9).
NOTE:
• A buzzer will sound if the vehicle is driven without releasing the parking brake. For
additional information, see “Warning
lights, indicator lights and audible remind-
ers” (P. 2-9).
5-24Starting and driving

• While the electronic parking brake is ap-plied or released, an operating sound is
heard from the lower side of the rear seat.
This is normal and does not indicate a
malfunction.
• When the electronic parking brake is fre- quently applied and released in a short pe-
riod of time, the parking brake may not
operate in order to prevent the parking
brake system from overheating. If this oc-
curs, operate the electronic parking brake
switch again after waiting approximately
1 minute.
• If the electronic parking brake must be ap- plied while driving in an emergency, pull up
and hold the parking brake switch. When
you release the parking brake switch, the
parking brake will be released.
• While pulling up the electronic parking brake switch during driving, the parking
brake is applied and a chime sounds. The
electronic parking brake indicator light
(red) in the meter and in the parking brake
switch illuminates. This does not indicate a
malfunction. The electronic parking brake
indicator light (red) in the meter and in the
parking brake switch turns off when the
parking brake is released. • When pulling the electronic parking brake
switch up with the ignition switch in the
OFF or AUTO ACC position, the parking
brake switch indicator light will continue
to illuminate for a short period of time.
WHEN TOWING A TRAILER
Depending on the weight of the vehicle and
trailer and the steepness of the slope, there
may be a tendency for the vehicle to move
backwards when starting from a standstill.
When this occurs, you can use the parking
brake switch in the same way as a conven-
tional lever type parking brake.
Before starting on sloping roads when tow-
ing a trailer, be sure to read the following to
prevent the vehicle from moving backwards
unintentionally.
• Release the parking brake switch as soonas the engine is delivering enough torque to
the wheels. The automatic brake hold function maintains
the braking force without the driver having to
depress the brake pedal when the vehicle is
stopped at a traffic light or intersection. As
soon as the driver depresses the accelerator
pedal again, the automatic brake hold func-
tion is deactivated and the braking force is
released. The operating status of the auto-
matic brake hold can be displayed on the
vehicle information display.
WARNING
• The automatic brake hold function is not
designed to hold the vehicle on a steep
hill or slippery road. Never use the auto-
matic brake hold when the vehicle is
stopped on a steep hill or slippery road.
Failure to do so may cause the vehicle to
move.
• The automatic brake hold function is de-
signed to operate on gradients between
—30% to +30%. Outside this range the
system may not operate. The automatic
brake hold warning may appear in the
Vehicle Information Display to request
that the driver retake control by de-
pressing the brake pedal.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the LDW system
could result in serious injury or death.
• This system is only a warning device to
inform the driver of a potential unin-
tended lane departure. It will not steer
the vehicle or prevent loss of control. It is
the driver’s responsibility to stay alert,
drive safely, keep the vehicle in the trav-
eling lane, and be in control of the vehicle
at all times. The LDW system will operate when the ve-
hicle is driven at speeds of approximately 37
mph (60 km/h) and above, and only when the
lane markings are clearly visible on the road.
The LDW system monitors the lane markers
on the traveling lane using the camera unit
O1
located above the inside mirror.
The LDW system warns the driver with an
indicator in the vehicle information display
and the steering wheel will vibrate, indicating
that the vehicle is beginning to leave the driv-
ing lane. For additional information, see
“LDW system operation” (P. 5-36).

LANE DEPARTURE WARNING (LDW)
Starting and driving5-35

LDW SYSTEM OPERATION
The LDW system provides a lane departure
warning function when the vehicle is driven atspeeds of approximately 37 mph (60 km/h)
and above and the lane markings are clear.
When the vehicle approaches either the left
or the right side of the traveling lane, thesteering wheel will vibrate and the LDW indi-
cator on the instrument panel will blink to
alert the driver.
The warning function will stop when the ve-
hicle returns inside of the lane markers.

•Do not use the LDW system under the
following conditions as it may not func-
tion properly:
– During bad weather (rain, fog, snow,
etc.).
– When driving on slippery roads, such
as on ice or snow.
– When driving on winding or uneven
roads.
– When there is a lane closure due to
road repairs.
– When driving in a makeshift or tem-
porary lane.
– When driving on roads where the lane
width is too narrow.
– When driving without normal tire
conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, nonstandard
wheels).
– When the vehicle is equipped with
non-original brake parts or suspen-
sion parts.
– When you are towing a trailer or
other vehicle. The system may not function properly under
the following conditions:
• On roads where there are multiple parallel
lane markers; lane markers that are faded
or not painted clearly; yellow painted lane
markers; non-standard lane markers; or
lane markers covered with water, dirt,
snow, etc.
• On roads where the discontinued lane markers are still detectable.
• On roads where there are sharp curves.
• On roads where there are sharply contrast- ing objects, such as shadows, snow, water,
wheel ruts, seams or lines remaining after
road repairs. (The LDW system could de-
tect these items as lane markers.)
• On roads where the traveling lane merges or separates.
• When the vehicle’s traveling direction does not align with the lane marker.
• When traveling close to the vehicle in front of you, which obstructs the lane camera
unit detection range.
• When rain, snow, dirt or an object adheres to the windshield in front of the lane cam-
era unit.
• When the headlights are not bright due to dirt on the lens or if the aiming is not ad-
justed properly. • When strong light enters the lane camera
unit. (For example, the light directly shines
on the front of the vehicle at sunrise or
sunset.)
• When a sudden change in brightness oc- curs. (For example, when the vehicle enters
or exits a tunnel or under a bridge.)
SYSTEM TEMPORARILY
UNAVAILABLE
If the vehicle is parked in direct sunlight under
high temperature conditions (over approxi-
mately 104°F [40°C]) and then started, the
LDW system may be deactivated automati-
cally and the following message will appear in
the vehicle information display: “Not avail-
able: High Camera Temp.”
When the interior temperature is reduced, the
LDW system will resume operating
automatically.
The LDW system is not designed to warn
under the following conditions:
• When you operate the lane change signaland change traveling lanes in the direction
of the signal. (The LDW system will become
operable again approximately 2 seconds
after the lane change signal is turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h).
