Steering wheel malfunctions INFINITI QX60 2017 Owner's Manual

LDP SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the LDP system. Failure to follow the
warnings and instructions for proper use
of the LDP system could result in serious
injury or death.
●The LDP system will not steer the ve-
hicle or prevent loss of control. It is the
driver’s responsibility to stay alert, drive
safely, keep the vehicle in the traveling
lane, and be in control of the vehicle at
all times.
● The LDP system is primarily intended
for use on well-developed freeways or
highways. It may not detect the lane
markers in certain roads, weather or
driving conditions.
● The LDP system may activate if you
change lanes without first activating
your turn signal or, for example, if a
construction zone directs traffic to
cross an existing lane marker. If this
occurs you may need to apply corrective
steering to complete your lane change. ●
Because the LDP may not activate un-
der the road, weather, and lane marker
conditions described in this section, it
may not activate every time your vehicle
begins to leave its lane and you will
need to apply corrective steering.
● When the LDP system is operating,
avoid excessive or sudden steering ma-
neuvers. Otherwise, you could lose con-
trol of the vehicle.
● The LDP system will not operate at
speeds below approximately 45 mph
(70 km/h) or if it cannot detect lane
markers.
● Do not use the LDP system under the
following conditions as it may not func-
tion properly:
– During bad weather (rain, fog, snow, etc.) .
– When driving on slippery roads, such as on ice or snow.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs. – When driving in a makeshift or tem-
porary lane.
– When driving on roads where the lane width is too narrow.
– When driving without normal tire conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, non-standard
wheels) .
– When the vehicle is equipped with nonoriginal brake parts or suspen-
sion parts.
– When you are towing a trailer or other vehicle.
● If the LDP system malfunctions, it will
cancel automatically. The LDP system
warning light (orange) will illuminate in
the display.
● If LDP system warning light (orange)
illuminates in the display, pull off the
road to a safe location and stop the
vehicle. Turn the engine off and restart
the engine. If the LDP system warning
light (orange) continues to illuminate,
have the LDP system checked. It is rec-
ommended that you visit an INFINITI
retailer for this service.

WARNING
●If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
● When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of
the vehicle, but the steering will be
harder to operate. Have the power
steering system checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
The power steering system is designed to pro-
vide power assist while driving to operate the
steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. When the temperature of the power steer-
ing system goes down, the power assist level will
return to normal. Avoid repeating such steering wheel operations that could cause the power
steering system to overheat.
You may hear a sound when the steering wheel is
operated quickly. However, this is not a malfunc-
tion.
If the electric power steering warning light illumi-
nates while the engine is running, it may indicate
the power steering system is not functioning
properly and may need servicing. Have the power
steering system checked. It is recommended that
you visit an INFINITI retailer for this service.
When the electric power steering warning light
illuminates with the engine running, there will be
no power assist for the steering, but you will still
have control of the vehicle. At this time, greater
steering effort is required to operate the steering
wheel, especially in sharp turns and at low
speeds.
For additional information, refer to “Power steer-
ing warning light” in the “Instruments and con-
trols” section of this manual.
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
