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 sys-
tem checked. It is recommended that you
visit an INFINITI retailer for this service.
Models with Direct Adaptive Steering®:
When the ignition switch is in the ON posi-
tion, the power steering warning light illumi-
nates. After starting the engine, the power steering warning light stays on for a few
seconds and turns off. This indicates that
Direct Adaptive Steering is operational. Drive
the vehicle after the power steering warning
light turns off.
If the power steering warning light illumi-
nates while driving, pull off the road to a safe
location and stop the vehicle. If the power
steering warning light turns off, you can drive
again. If the power steering warning light
continues to illuminate, have the Direct
Adaptive Steering checked. It is recom-
mended that you visit an INFINITI retailer for
this service. For additional information, see

Models with electric power steering:
When the ignition switch is in the ON posi-
tion, the power steering warning light illumi-
nates. After starting the engine, the power
steering warning light turns off. This indicates
the electric power steering is operational.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the electric power steering is not func-
tioning properly and may need servicing. It is
recommended that you have the electric
power steering checked by an INFINITI
retailer.

lem with the CVT system. If this warning
comes on, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.
CVT (AT) hot Power reduced
This transmission has a high fluid tempera-
ture protection mode. If the fluid temperature
becomes too high (for example, climbing
steep grades in high temperatures with heavy
loads), engine power and, under some condi-
tions, vehicle speed will be decreased auto-
matically to reduce the chance of transmis-
sion damage. Vehicle speed can be controlled
with the accelerator pedal, but the engine
and vehicle speed may be reduced.
WARNING
When the high fluid temperature protec-
tion mode operation occurs, vehicle speed
may be gradually reduced. The reduced
speed may be lower than other traffic,
which could increase the chance of a colli-
sion. Be especially careful when driving. If
necessary, pull to the side of the road at a
safe place and allow the transmission to
return to normal operation; or have it re-
paired if necessary.
Engine hot Power reduced
This engine has a high fluid temperature pro-
tection mode. If the fluid temperature be-
comes too high (for example, climbing steep
grades in high temperatures with heavy
loads), engine power and, under some condi-
tions, vehicle speed will be decreased auto-
matically to reduce the chance of engine
damage. Vehicle speed can be controlled
with the accelerator pedal, but the engine
and vehicle speed may be reduced.

• 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 ve-
hicle 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 electronic parking brake can be applied
or released automatically or by operating the
parking brake switch.
AUTOMATIC OPERATION
The electronic parking brake will apply auto-
matically if the ignition switch is placed in the
OFF position when the brake force is main-
tained by the automatic brake hold function.
