2021 INFINITI Q50 Owner's Manual

— If an electrical equipment is being usedin or near the vehicle
— There is a malfunction in the TPMS system
— There is a malfunction in the horn or hazard indicators
. If the Tire Inflation Indicator does not
operate due to TPMS interference, move
the vehicle about 3 ft (1 m) backward or
forward and try again.
If the Tire Inflation Indicator is not working,
use a tire pressure gauge.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss of
control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving
practices could cause you to lose control of
your vehicle. As with any vehicle, a loss of
control could result in a collision with other
vehicles or objects, or cause the vehicle to rollover, particularly if the loss of control
causes the vehicle to slide sideways.
Be
attentive at all times, and avoid driving when
tired. Never drive when under the influence
of alcohol or drugs (including prescription or
over-the-counter drugs which may cause
drowsiness). Always wear your seat belt as
outlined in the “Seat belts” (P.1-12) of this
manual, and also instruct your passengers to
do so.
Seat belts help reduce the risk of injury in
collisions and rollovers. In a rollover crash,
an unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person properly wearing a seat
belt.
OFF-ROAD RECOVERY
If driving the right side or left side wheels
may unintentionally leave the road surface.
Maintain control of the vehicle by following
the procedure below. Please note that this
procedure is only a general guide. The vehicle
must be driven as appropriate based on the
conditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering
wheel with both hands and try to hold
a straight course. 4. When appropriate, slowly release the
accelerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while the
vehicle speed is reduced. Do not attempt
to drive the vehicle back onto the road
surface until vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return
to the road surface. When all tires are on
the road surface, steer the vehicle to stay
in the appropriate driving lane.
.If you decide that it is not safe to
return the vehicle to the road surface
based on vehicle, road or traffic
conditions, gradually slow the vehicle
to a stop in a safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving
on under-inflated tires.
Rapid air pressure loss can affect the
handling and stability of the vehicle, espe-
cially at highway speeds.
Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspect the tires for wear and

damage. See “Wheels and tires” (P.8-25) of
this manual.
If a tire rapidly loses air pressure or “blows-
out” while driving maintain control of the
vehicle by following the procedure below.
Please note that this procedure is only a
general guide. The vehicle must be driven as
appropriate based on the conditions of the
vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
.The vehicle generally moves or pulls
in the direction of the flat tire.
. Do not rapidly apply the brakes.
. Do not rapidly release the accelerator
pedal.
. Do not rapidly turn the steering
wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold
a straight course. 3. When appropriate, slowly release the
accelerator pedal to gradually slow the
vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from
traffic if possible.
5. Lightly apply the brake pedal to gradu- ally stop the vehicle.
6. Turn on the hazard warning flashers and either contact a roadside emergency
service to change the tire or see “Jacking
up the vehicle and replacing tires” (P.8-
37) of this Owner’s Manual.
DRINKING ALCOHOL/DRUGS
AND DRIVING
WARNING
Never drive under the influence of alco-
hol or drugs. Alcohol in the bloodstream
reduces coordination, delays reaction
time and impairs judgement. Driving
after drinking alcohol increases the like-
lihood of being involved in an accident
injuring yourself and others. Addition-
ally, if you are injured in an accident,
alcohol can increase the severity of the
injury. INFINITI is committed to safe driving. How-
ever, you must choose not to drive under the
influence of alcohol. Every year thousands of
people are injured or killed in alcohol-related
accidents. Although the local laws vary on
what is considered to be legally intoxicated,
the fact is that alcohol affects all people
differently and most people underestimate
the effects of alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs).
Don’t drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or some
other physical condition.
INTELLIGENT ALL-WHEEL
DRIVE (AWD) DRIVING SAFETY
PRECAUTIONS (AWD models)
WARNING
.
Do not drive beyond the performance
capability of the tires, even with
Intelligent AWD engaged. Accelerat-
ing quickly, sharp steering maneuvers
or sudden braking may cause loss of
control.
. 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 rear 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
attempt 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 dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing), or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure you
inform test facility personnel that
your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or personal injury.
. When a wheel is off the ground due
to an unlevel surface, do not spin the
wheel excessively.WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in
an emergency. (The engine will stop
when the ignition switch is pushed 3
consecutive times or the ignition switch
is pushed and held for more than 2
seconds.) If the engine stops while the
vehicle is being driven, this could lead to
a crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the shift lever to the
P (Park) position.

not start, push the ignition switch to
OFF and wait 10 seconds before crank-
ing again, otherwise the starter could be
damaged.
4. Warm-up
Allow the engine to idle for at least 30
seconds after starting. Do not race the
engine while warming it up. Drive at
moderate speed for a short distance
first, especially in cold weather. In cold
weather, keep the engine running for a
minimum of 2 - 3 minutes before shut-
ting it off. Starting and stopping the
engine over a short period of time may
make the vehicle more difficult to start.

The automatic transmission in your vehicle is
electronically controlled by a transmission
control module to produce maximum effi-
ciency and smooth operation.
Shown on the following pages are the
recommended operating procedures for this
transmission. Follow these procedures for
maximum vehicle performance and driving
enjoyment.
Starting the vehicle
After starting the engine, fully depress the
foot brake pedal and push the shift lever
button before shifting the shift lever to the R
(Reverse), N (Neutral), D (Drive) or Manual
shift mode position. Be sure the vehicle is
fully stopped before attempting to shift the
shift lever.
This Automatic Transmission (AT) model is
designed so that the foot brake pedal must
be depressed before shifting from P (Park)
to any drive position while the ignition
switch is in the ON position.
The shift lever cannot be moved out of the P
(Park) position and into any of the other
gear positions if the ignition switch is placed
in the LOCK, OFF or ACC position.
1. Keep the foot brake pedal depressed andpush the shift lever button to shift into a
driving gear. 2. Release the parking brake and foot
brake, then gradually start the vehicle in
motion.
WARNING
.Do not depress the accelerator pedal
while shifting from P (Park) or N
(Neutral) to R (Reverse), D (Drive) or
manual shift mode. Always depress
the brake pedal until shifting is
completed. Failure to do so could
cause you to lose control and have
an accident.
. Cold engine idle speed is high, so use
caution when shifting into a forward
or reverse gear before the engine has
warmed up.
. Never shift to either P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is
moving reversing. This could cause an
accident or damage the transmission.
. Do not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
