steering wheel INFINITI QX55 2023 Manual PDF

The chassis control is an electric control mod-
ule that includes the following functions:
• Active Trace Control
• Active Engine Brake
• Active Ride Control
ACTIVE TRACE CONTROL
The Active Trace Control senses driving
based on the driver’s steering and
acceleration/braking patterns, and controls
brake pressure at individual wheels to aid
tracing at corners and help smooth vehicle
response.
When the lower display is used to turn off the
VDC system, the Active Trace Control sys-
tem is also turned off.
When the PERSONAL mode is selected, the
Active Trace Control can be set to ON (en-
abled) or OFF (disabled). For additional infor-
mation, see “INFINITI Drive Mode Selector”
(P. 5-29).When the Active Trace Control is operated
and the “Chassis Control” mode is selected in
the vehicle information display, the Active
Trace Control graphics are shown in the ve-
hicle information display. For additional in-
formation, see “Vehicle information display”
(P. 2-19).
If the chassis control warning message ap-
pears in the vehicle information display, it
may indicate that the Active Trace Control is
not functioning properly. Have the system
checked as soon as possible. It is recom-
mended that you visit an INFINITI retailer for
this service.
WARNING
The Active Trace Control may not be effec-
tive depending on the driving condition. Al-
ways drive carefully and attentively.
When the Active Trace Control is operating,
you may feel a pulsation in the brake pedal
and hear a noise. This is normal and indicates
that the Active Trace Control is operating
properly.
You may also feel deceleration when the Ac-
tive Trace Control is operating. However, this
is not a malfunction.

5-144Starting and driving

To shut off the engine in an emergency situ-
ation while driving, perform the following
procedure:
– Rapidly push the push-button ignitionswitch three consecutive times in less than
1.5 seconds, or
– Push and hold the push-button ignition switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires. When the low tire pres-
sure warning light is lit, and the “Tire Pressure
Low - Add Air” or “Flat Tire-Visit dealer” (if so
equipped) warning appears in the vehicle in-
formation display, one or more of your tires is
significantly under-inflated. The system also
displays pressure of all tires (except the spare
tire) on the vehicle information display screen
by sending a signal from a sensor that is
installed in each wheel. If the vehicle is being
driven with low tire pressure, the TPMS will
activate and warn you of it by the low tire
pressure warning light. This system will acti-
vate only when the vehicle is driven at speeds
above 16 mph (25 km/h). For additional in-
formation, see “Warning lights, indicator
lights and audible reminders” (P. 2-9) and
“Tire Pressure Monitoring System (TPMS)”
(P. 8-27).
WARNING
• Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use. •
If the low tire pressure warning light illu-
minates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road to
a safe location and stop the vehicle as
soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage could
occur and may lead to an accident and
could result in serious personal injury.
Check the tire pressure for all four tires.
Adjust the tire pressure to the recom-
mended COLD tire pressure shown on
the Tire and Loading Information label to
turn the low tire pressure warning light
OFF. If the light still illuminates while
driving after adjusting the tire pressure,
a tire may be flat or the TPMS may be
malfunctioning. If you have a flat tire,
replace it with a replacement tire as soon
as possible. If no tires are flat and all tires
are properly inflated, have the vehicle
checked. It is recommended that you
visit an INFINITI retailer for this service.

6. After the engine cools down, check thecoolant level in the engine coolant reser-
voir tank with the engine running. Add
coolant to the engine coolant reservoir
tank if necessary. Have your vehicle re-
paired. It is recommended that you visit an
INFINITI retailer for this service. When towing your vehicle, all jurisdictions
and local regulations for towing must be fol-
lowed. Incorrect towing equipment could
damage your vehicle. Towing instructions are
available from an INFINITI retailer. Local ser-
vice operators are generally familiar with the
applicable laws and procedures for towing.
To assure proper towing and to prevent ac-
cidental damage to your vehicle, INFINITI
recommends having a service operator tow
your vehicle. It is advisable to have the service
operator carefully read the following
precautions:
WARNING
• Never ride in a vehicle that is being
towed.
• Never get under your vehicle after it has
been lifted by a tow truck.
CAUTION
• When towing, make sure that the trans-
mission, axles, steering system and pow-
ertrain are in working condition. Use dol-
lies or flatbed if any of the listed systems
are not working.
• Always attach safety chains before
towing. For additional information about towing your
vehicle behind a Recreational Vehicle (RV),
see “Flat towing for all wheel drive vehicle”
(P. 10-20).
NOTE:
If the battery is completely drained, the
transmission will not manually shift to other
positions. For shifting to other positions,
charge the battery or supply power follow-
ing the jump starting procedure. Push the
park button to shift to the P (Park) position
before shifting to other positions.
TOWING RECOMMENDED BY
INFINITI
INFINITI recommends towing your vehicle
based upon the type of drivetrain. For addi-
tional information, refer to the diagrams in
this section to ensure that your vehicle is
properly towed.
TOWING YOUR VEHICLE
6-8In case of emergency

Rocking a stuck vehicle
WARNING
• Stand clear of a stuck vehicle.
• Do not spin your tires at high speed. This
could cause them to explode and result in
serious injury. Parts of your vehicle could
also overheat and be damaged.
If your vehicle is stuck in sand, snow, mud,
etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control (VDC) system.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and backward.
• Shift back and forth between R (Re- verse) and D (Drive).
• Apply the accelerator as little as pos- sible to maintain the rocking motion.
• Release the accelerator pedal before shifting between R (Reverse) and D
(Drive).
• Do not spin the tires above 35 mph (55 km/h). 5. If the vehicle cannot be freed after a few
tries, contact a professional towing ser-
vice to remove the vehicle.
6-10In case of emergency

Doors and engine hood:Check that the doors
and engine hood operate properly. Also en-
sure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary
latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication
frequently.
Check that the gas stays or struts properly
and securely hold the hood, trunk, or rear
hatch fully open. If the hood, trunk, or rear
hatch is not held open, have the gas stays or
struts replaced.
Lights*: Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure no wheel nuts are miss-
ing, and check for any loose wheel nuts.
Tighten if necessary.
Tire rotation*: Rotate tires at the specified
interval shown in the maintenance schedule.
Tires*: Check the pressure with a gauge of-
ten and always prior to long distance trips. If necessary, adjust the pressure in all tires, in-
cluding the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.
Tire Pressure Monitoring System (TPMS)
tire pressure sensor:
It is recommended that
you replace the TPMS tire pressure sensor
assembly when the tires are replaced due to
wear or age.
Wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect un-
even or abnormal tire wear, there may be a
need for wheel alignment.
If the steering wheel or seat vibrates at nor-
mal highway speeds, wheel balancing may be
needed.
