2018 INFINITI Q50-HYBRID air condition

5-10Starting and driving
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-
39) 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.

5-18Starting and driving
For passing or hill climbing, fully depress the
accelerator pedal to the floor. This shifts the
transmission down into the lower gear,
depending on the vehicle speed.
Fail-safe
When the fail-safe operation occurs, note
that the transmission will be locked in any of
the forward gears according to the condi-
tion.
If the vehicle is driven under extreme
conditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, push the ignition
switch to the OFF position and wait for 3
seconds. Then push the ignition switch back
to the ON position. The vehicle should
return to its normal operating condition. If
it does not return to its normal operating
condition, have the transmission checked
and repaired, if necessary. It is recom-
mended you visit an INFINITI retailer for
this service.

Shift lock release
If the 12-volt battery charge is low or
discharged, the shift lever may not be moved
from the P (Park) position even with the
brake pedal depressed and the shift lever
button pushed.
To move the shift lever, perform the follow-
ing procedure:
1. Push the ignition switch to the OFF orLOCK position.
2. Apply the parking brake.
3. Remove the shift lock cover
using a
suitable tool.
4. Push down the shift lock
using
mechanical key as illustrated. 5. Push the shift lever button
and move
the shift lever to N (Neutral) position
while holding down the shift lock.
If the lever cannot be moved out of P (Park),
have the automatic transmission system
checked as soon as possible. It is recom-
mended you visit an INFINITI retailer for this
service.
Adaptive Shift Control (ASC)
The adaptive shift control system automati-
cally operates when the transmission is in
the D (Drive) position and selects an appro-
priate gear depending on the road conditions
such as uphill, downhill or curving roads.
Control on uphill and curving roads:
A low gear is maintained that suits the
degree of the slope or curve to allow smooth
driving with a small number of shifts.
Control on downhill roads:
The adaptive shift control system shifts to a
low gear that suits the degree of the slope to
reduce the number of times that the brake
must be used.
Control on winding roads:
A low gear is maintained on continuous
curves that involve repeated acceleration
and deceleration, so that smooth accelera-
tion is available instantly when the accel-
erator pedal is depressed.

JVS1123X
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the radar sensor
detects a slower
moving vehicle ahead, the system will reduce
the vehicle speed so that your vehicle
follows the vehicle in front at the selected
distance.
The system automatically controls the throt-
tle and applies the brakes (up to approxi-
mately 40% of vehicle braking power) if
necessary.
The detection range of the sensor is approxi-
mately 650 ft (200 m) ahead.
Vehicle-to-vehicle distance control
mode operation
The vehicle-to-vehicle distance control
mode is designed to maintain a selected
distance and reduce the speed to match the
slower vehicle ahead; the system will de-
celerate the vehicle as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the ICC
system can only apply up to approximately
40% of the vehicle’s total braking power.
This system should only be used when traffic
conditions allow vehicle speeds to remain
fairly constant or when vehicle speeds
change gradually. If a vehicle moves into
the traveling lane ahead or if a vehicle
traveling ahead rapidly decelerates, the
distance between vehicles may become
closer because the ICC system cannot
decelerate the vehicle quickly enough. If this
occurs, the ICC system will sound a warning
chime and blink the system display to notify
the driver to take necessary action.
The system will cancel and a warning chime
will sound if the speed is below approxi-
mately 15 MPH (24 km/h) and a vehicle is
not detected ahead. The system will also
disengage when the vehicle goes above the
maximum set speed.
See “Approach warning” (P.5-82). The following items are controlled in the
vehicle-to-vehicle distance control mode:
.
When there are no vehicles traveling
ahead, the vehicle-to-vehicle distance
control mode maintains the speed set
by the driver. The set speed range is
between approximately 20 and 90 MPH
(32 and 144 km/h).
. When there is a vehicle traveling ahead,
the vehicle-to-vehicle distance control
mode adjusts the speed to maintain the
distance, selected by driver, from the
vehicle ahead. The adjusting speed range
is up to the set speed. If the vehicle
ahead comes to a stop, the vehicle
decelerates to a standstill within the
limitations of the system. The system
will cancel once it judges a standstill with
a warning chime.
. When the vehicle traveling ahead has
moved out from its lane of travel, the
vehicle-to-vehicle distance control mode
accelerates and maintains vehicle speed
up to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach
stationary and slow moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead when approaching toll gates or traffic
congestion.
Starting and driving5-75

driven on winding roads, narrow roads, hilly
roads or when entering or exiting a curve. In
these cases you will have to manually
control the proper distance ahead of your
vehicle.
Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or
vehicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed.
.When the vehicle ahead is not detected
and your vehicle is traveling below the
speed of 15 MPH (24 km/h)
. When the system judges the vehicle is at
standstill
. When the shift lever is not in the D
position or manual shift mode
. When the parking brake is applied
. When the INFINITI Drive Mode Selector
is turned to the SNOW mode
. When the VDC system is turned off
. When ABS or VDC (including the traction
control system) operates
. When distance measurement becomes
impaired due to adhesion of dirt or
obstruction to the sensor .
When a wheel slips
. When the radar signal is temporarily
interrupted
Vehicle-to-vehicle distance control
mode limitations
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. The system is primarily intended for
use on straight, dry, open roads with
light traffic. It is not advisable to use
the system in city traffic or con-
gested areas.
. This system will not adapt automati-
cally to road conditions. This system
should be used in evenly flowing
traffic. Do not use the system on
roads with sharp curves, or on icy
roads, in heavy rain or in fog.
. As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absent-minded driving, or over- come poor visibility in rain, fog, or
other bad weather. Decelerate the
vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
. If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel once it judges
that the vehicle has come to a
standstill and sound a warning chime.
To prevent the vehicle from moving,
the driver must depress the brake
pedal.
. Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The vehicle-to-vehicle
distance control mode of the ICC
system may not be able to maintain
the selected distance between vehi-
cles (following distance) or selected
vehicle speed under some circum-
stances.
. The system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, never use the ICC system
under the following conditions:
