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 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.
ELECTRONIC PARKING BRAKE
(switch type)
The electronic parking brake can be applied
or released by operating the parking brake
switch.
WARNING
• Before leaving the vehicle, move the shift
position to the P (Park) position and
check that the electronic parking brake
warning light is illuminated to confirm
that the electronic parking brake is ap-
plied. The electronic parking brake
warning light will remain on for a period
of time after the driver’s door is locked.
CAUTION
When parking in an area where the outside
temperature is below 32°F (0°C), the park-
ing brake, if applied, may freeze in place
and may be difficult to release.
For safe parking, it is recommended that
you place the shift position in the P (Park)
position and securely block the wheels.
NOTE:
• To keep the electronic parking brake re- leased after the engine is turned off, place
the ignition switch in the OFF position, de-
press the brake pedal and push down the
parking brake switch before opening the
driver’s door.

mended that you visit an INFINITI retailer
for this service.
• The STANDARD (2WD models)/AUTO (4WD models) mode will be selected first
each time the ignition switch is placed in
the ON position.
WARNING
Do not stare at the Drive Mode Selector or
the display while driving so that full atten-
tion may be given to vehicle operation.
STANDARD (2WD models)/AUTO
(AWD models)
This is the standard mode that is most suit-
able for normal driving.
SPORT MODE
Adjusts the engine points for a higher
response.
The setting of the steering system is adjusted
to moderately increase steering wheel effort
for a sporty feel.
NOTE:
In the SPORT mode, fuel economy may be
reduced.
SNOW MODE
This mode makes it easier to start and drive
on snowy roads and frozen roads.
CAUTION
Never drive on dry, hard surface roads in
the SNOW mode, as this will overload
the powertrain and may cause a serious
malfunction. Additionally, this will cause
premature tire wear and reduced fuel
economy. When the SNOW mode is se-
lected, small vibration in cornering may oc-
cur. This is not a malfunction.
PERSONAL MODE
This mode is used for adjusting the steering
mode and drive modes. Turn the PERSONAL
mode off for normal driving.
