ECU INFINITI QX30 2019 Repair Manual

START3
The engine starter activates and the engine
will start. As soon as the engine has started,
release the key immediately. It will return to
the ON position.
NOTE
For vehicles fitted with Idle Stop/Start Sys-
tem:
When the engine is automatically stopped
by the Idle Stop/Start System the ignition
switch can still be operated as usual.
At the end of a journey turn the ignition OFF
to avoid a discharged battery. The Idle
Stop/Start System does not automatically
turn ignition off.
Vehicles with Intelligent Key are equipped with
keys featuring an integrated Intelligent Key
function and in some cases a detachable push-
button ignition switch (Start/Stop button).
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the ve-
hicle. This occurs, for example, when starting
the engine.
When you insert the push-button ignition
switch into the ignition lock, the system needs
approximately two seconds recognition time.
You can then use the push-button ignition
switch.
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 pressed 3 consecutive
times in quick succession or the ignition
switch is pushed and held for more than 2
seconds.) If the engine stops while the ve-
hicle is being driven, this could lead to a
crash and serious injury.
Before operating the push-button ignition
switch:
•Select P (Park).Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. Prerequisite
for this is that:
•You do not depress the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
To start the vehicle without actively using the
key:
•The push-button ignition switch must be
inserted in the ignition lock.
•The key must be in the vehicle.
•The vehicle must not be locked with the
key or Intelligent Key (see "Keys").
Do not keep the Intelligent Key:
•With electronic devices, for example a mo-
bile phone or another key.
•With metallic objects, for example coins or
metal film.
•Inside metallic objects, for example a metal
case.
This can affect the functionality of the Intel-
ligent Key.
PUSH-BUTTON IGNITION SWITCH
(IF EQUIPPED)
5-14Starting and driving

You do not have to remove the start/stop
button from the ignition lock when you leave
the vehicle. You should, however, always
take the key with you when leaving the ve-
hicle. As long as the key is in the vehicle:
•The vehicle can be started using the push-
button ignition switch.
•The electrically powered equipment can be
operated.
EMERGENCY ENGINE SHUT OFF
To shut off the engine in an emergency situ-
ation while driving, perform the following
procedure:
•Rapidly push the push-button ignition
switch 3 consecutive times in less than
1.5 seconds, or
•Push and hold the push-button ignition
switch for more than 2 seconds.
•Make sure the area around the vehicle is
clear.
•Check fluid levels such as engine oil, cool-
ant, brake fluid, and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
•Check that all windows and lights are
clean.
•Visually inspect tires for their appearance
and condition. Measure and check the tire
pressure for proper inflation.
•Check that all doors are closed.
•Position seat and adjust head restraints/
headrests.
•Adjust the inside and outside rear view
mirrors.
•Fasten your seat belt and ask all passen-
gers to do likewise.
•Check the operation of the warning lights
when the ignition switch is pushed to the
ON position.

5-16Starting and driving

P (Park):
CAUTION
To prevent transmission damage, use the P
(Park) position only when the vehicle is
completely stopped.
Use this position when the vehicle is parked
or when starting the engine. Always make
sure that the vehicle is completely stopped
before pressing button
1to engage the P
(Park) position. For maximum safety, the
brake pedal must be depressed before en-
gaging the P (Park) position. Use this position
together with the parking brake. When park-
ing on a hill, first depress the brake pedal,
apply the parking brake and then engage the
P (Park) position. The parking lock should not
be used as a brake when parking. In order tosecure the vehicle, always apply the electric
parking brake in addition to the parking lock.
In the event of a malfunction of the vehicle&#39;s
electronics, the transmission may lock in po-
sition P (Park). Have the vehicle electronics
checked immediately. It is recommended you
visit an INFINITI retailer for this service.
Park position P is automatically engaged if:
•You switch off the engine using the key
and remove the key.
•You open the driver&#39;s door when the ve-
hicle is stationary or driving at very low
speed and the transmission is in position D
(Drive) or R (Reverse).
R (Reverse):
CAUTION
To prevent transmission damage, use the R
(Reverse) position only when the vehicle is
completely stopped.
Use this position to back up the vehicle.
Make sure the vehicle is completely stopped
before selecting the R (Reverse) position.The
brake pedal must be depressed and the shift
lever button pushed in to move the shift le-
ver from P (Park), N (Neutral) or any drive
position to R (Reverse).N (Neutral):
Neither forward nor reverse gear is engaged.
The engine can be started in this position. You
may shift to N (Neutral) and restart a stalled
engine while driving the vehicle.
D (Drive):
Use this position for all normal forward driv-
ing.
The automatic transmission changes gear
automatically. All forward gears are avail-
able.
Changing gear
The automatic transmission shifts to the in-
dividual gears automatically when it is in
transmission position D (Drive). Shifting is de-
termined by:
•The selected drive program.
•The position of the accelerator pedal.
•The road speed.
Accelerator pedal position:
Your style of driving influences how the au-
tomatic transmission shifts gear:
•little throttle: early upshifts
•more throttle: late upshifts

WARNING
•Be sure the parking brake is fully re-
leased before driving. Failure to do so
can cause brake failure and lead to an
accident.
•Do not release the parking brake from
outside the vehicle.
•Do not use the shift lever in place of the
parking brake. When parking, be sure
the parking brake is fully engaged.
•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 assis-
tance of others, or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm
day can quickly become high enough to
cause a significant risk of injury or death
to people and pets.The function of the electric parking brake is
dependent on the on-board voltage. If the
on-board voltage is low or if there is a mal-
function in the system, it may not be possible
to apply the released parking brake. If this is
the case:
•Only park the vehicle on level ground and
secure it to prevent it from rolling away.
•Shift the automatic transmission to posi-
tion P (Park).
•It is recommended you contact an INFINITI
retailer.
It may not be possible to release an applied
parking brake if the on-board voltage is low
or if there is a malfunction in the system. It is
recommended you contact an INFINITI re-
tailer.
The electric parking brake carries out a func-
tion check at regular intervals when the en-
gine is switched off. Noises that occur are
normal.

Storing the current speed or calling up the
last stored speed:
WARNING
If you call up a stored speed and this is
different from the current speed, the ve-
hicle accelerates or brakes. If you do not
know what the stored speed is, the vehicle
may accelerate or brake unexpectedly.
There is a risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store
the desired speed again.
1. Briefly pull the cruise control lever to-
wards you
2.
2. Remove your foot from the accelerator
pedal. The first time cruise control is acti-
vated, it stores the current speed or if a
speed has previously been stored, it regu-
lates the speed of the vehicle to the pre-
viously stored speed.
Setting a speed
Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.
1. Press the cruise control lever up

Starting and driving5-73

CAUTION
Never tow the vehicle with one axle raised.
This may damage the differential. Damage
of this sort is not covered by the warranty.
All wheels must be fully raised (see &#34;Four-
Wheel Drive (4WD) models&#34;)
4WD, together with VDC, improves the trac-
tion of your vehicle whenever a drive wheel
spins due to insufficient grip.
If you fail to adapt your driving style, 4WD
can neither reduce the risk of an accident nor
override the laws of physics. 4WD cannot
take account of road, weather, and traffic
conditions. 4WD is only an aid. You are re-
sponsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
If a drive wheel spins due to insufficient grip
•When pulling away, only depress the ac-
celerator pedal as far as is necessary.
•Accelerate less when driving.
NOTE
In wintry driving conditions, the maximum
effectiveness of 4WD can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
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 applied and
the P (Park) position engaged. Failure to
do so could cause the vehicle to move
unexpectedly or roll away and result in
an accident.
•When parking the vehicle, make sure the
P (Park) position is engaged. The shift
lever cannot be moved out of the P
(Park) position without depressing the
brake pedal.
•Never leave the engine running while the
vehicle is unattended.
•Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls or move the
vehicle. Unattended children could be-
come 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 assis-
tance of others, or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm
day can quickly become high enough to
cause a significant risk of injury or death
to people and pets.
CAUTION
Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its
drive train could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
•The electric parking brake must be applied.
•The transmission must be in position P
(Park) and the transmission position dis-
play must show P in the vehicle informa-
tion display.
•The key must be removed from the ignition
switch.
•On uphill or downhill gradients, the front
wheels must be turned towards the curb.
