steering INFINITI QX30 2018 Repair Manual

•Heavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed.
•Unsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
•Secure heavy loads in the cargo area as
far forward and as low as possible. Do
not equip the vehicle with tires larger
than specified in this manual. This could
cause your vehicle to roll over.
•Do not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move suddenly
and injure your hands. Instead drive with
your fingers and thumbs on the outside
of the rim.
•Before operating the vehicle, ensure
that the driver and all passengers have
their seat belts fastened.
•Always drive with the floor mats in place
as the floor may become hot.
•Lower your speed when encountering
strong crosswinds. With a higher center of gravity, your INFINITI is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
•Do not drive beyond the performance
capability of the tires, even with AWD
engaged.
•For AWD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to any
drive or reverse position with the engine
running. Doing so may result in drive-
train 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
damage or unexpected vehicle move-
ment which could result in serious ve-
hicle damage or personal injury.
•When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
•Accelerating quickly, sharp steering ma-
neuvers or sudden braking may cause
loss of control.
•If at all possible, avoid sharp turning ma-
neuvers, particularly at high speeds.
Your INFINITI vehicle has a higher cen-
ter of gravity than a passenger car. The
vehicle is not designed for cornering at
the same speeds as passenger cars. Fail-
ure to operate this vehicle correctly
could result in loss of control and/or a
rollover accident.
•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. .
•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.

Steering wheel gearshift paddles
1Left steering wheel gearshift paddle
(shifts down)
2Right steering wheel gearshift paddle
(shifts up)
In drive program M, you can change gear
yourself using the steering wheel gearshift
paddles.
If you pull the left or right steering wheel
gearshift paddle when in automatic drive
program E or S, the automatic transmission
shifts into drive program M for a limited time.
Depending on which gearshift paddle is
pulled, the automatic transmission immedi-
ately shifts into the next gear down or up.
Automatic drive programs
Drive program E is characterized by the fol-
lowing:
•Comfort-oriented engine settings.
•Optimal fuel consumption resulting from
the automatic transmission shifting up
sooner.
•The vehicle pulling away more gently in
forward and reverse gears unless the ac-
celerator pedal is depressed fully.
•Increased sensitivity. This improves han-
dling on slippery road surfaces, for ex-
ample.
•The automatic transmission shifting up
sooner. This results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin.
Drive program S is characterized by the fol-
lowing:
•Sporty engine settings.
•The automatic transmission shifting up
later.
•As a result of the later automatic transmis-
sion shift points, the fuel consumption
possibly being higher.
Manual drive program
In manual drive program M, you can change
gear yourself by using the steering wheel
gearshift paddles. For this, the transmission
must be in position D (Drive). The gear cur-
rently selected and engaged is shown in the
vehicle information display
Manual drive program M differs from drive
programs E and S with regard to spontaneity,
responsiveness and smoothness of gear
changes.
Using manual gears:
3 To use the engine's braking effect
2 To use the braking effect of the engine on downhill gradients and for driving on steep
mountain roads, in mountainous terrain or
in arduous conditions.
1 To use the braking effect of the engine on extremely steep downhill gradients and on
long downhill stretches.

5-24Starting and driving

Activating the manual drive program:
•Permanently: Press the drive mode switch
1repeatedly until M appears in the ve-
hicle information display. Manual drive
program M remains active until drive pro-
gram E or S is engaged.
•Temporarily: Pull the right or left steering
wheel gearshift paddle (see "Steering
wheel gearshift paddles" later in this sec-
tion). Manual drive program M is tempo-
rarily active. Depending on which gearshift
paddle is pulled, the automatic transmis-
sion immediately shifts into the next gear
down or up. When manual drive program M is activated
via the steering wheel gearshift paddles, the
temporarily active manual drive program M
will be deactivated automatically after a lim-
ited time, if the driving situation permits. The
automatic transmission switches to the pre-
viously activated drive program E or S. When
driving on downhill gradients, the temporarily
active manual drive program M will only be
deactivated if the accelerator pedal is de-
pressed while the vehicle is rolling downhill.
Upshifting:
Pull the right-hand steering wheel gearshift
paddle (see "Steering wheel gearshift
paddles" earlier in this section). The auto-
matic transmission shifts up to the next gear.
In order to prevent engine damage the auto-
matic transmission automatically shifts up if
the maximum engine speed on the currently
engaged gear is reached and you depress the
accelerator pedal.
Gearshift recommendation:
The gearshift recommendations assist you in
adopting an economical driving style. The
recommended gear is shown in the vehicle
information display.
Shift to recommended gear1according to
gearshift recommendation
2when shown in
the vehicle information display.
Downshifiting:
Pull the left-hand steering wheel gearshift
paddle (see "Steering wheel gearshift
paddles" earlier in this section). The auto-
matic transmission shifts down to the next
gear.
If you slow down or stop without shifting
down, the automatic transmission automati-
cally shifts down.
NSD587NSD589
Starting and driving5-25

For maximum acceleration, pull the left-hand
steering wheel gearshift paddle until the
transmission selects the optimum gear for
the current speed.
If the engine exceeds the maximum engine
speed when shifting down, the automatic
transmission protects against engine dam-
age by not shifting down.Kickdown:
You can also use kickdown for maximum ac-
celeration in manual drive program M
•Depress the accelerator pedal beyond the
pressure point The transmission shifts to a
lower gear depending on the engine
speed.
•Shift back up once the desired speed is
reached.
During kickdown, you cannot shift gears us-
ing the steering wheel gearshift paddles.
If you apply full throttle, the automatic trans-
mission shifts up to the next gear when the maximum engine speed is reached. This pre-
vents the engine from overrevving.
Deactivating the temporary manual drive
program:
Pull and hold the right steering wheel gear-
shift paddle until the automatic transmission
shifts into the last active automatic drive pro-
gram E or S.
When manual drive program M is deacti-
vated, the automatic transmission in auto-
matic drive program E or S may shift from the
current gear into a higher or lower gear. This
is dependent on the position of the accelera-
tor pedal, speed and load.
Problems with the transmission:
Problem Possible causes/consequences and solutions
The transmission has
problems shifting
