2020 INFINITI QX50 parking brake

switch in the OFF position and wait for
10 seconds. Then place the ignition switch
back in the ON position. The vehicle should
return to its normal operating condition. If it
does not return to its normal operating con-
dition, have the transmission checked and
repaired, if necessary. It is recommended
that you visit an INFINITI retailer for this
service.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs, ve-
hicle speed may be gradually reduced. The
reduced speed may be lower than other
traffic, which could increase the chance of a
collision. Be especially careful when driving.
If necessary, pull to the side of the road at a
safe place and allow the transmission to re-
turn to normal operation, or have it re-
paired if necessary.
WARNING
∙ Be sure the parking brake is fully releasedbefore 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.
The electronic parking brake is automatically
released as soon as the vehicle starts and the
accelerator pedal is depressed.
The driver’s seat belt needs to be fastened.

WHEN TOWING A TRAILER
Depending on the weight of the vehicle and
trailer and the steepness of the slope, there
may be a tendency for the vehicle to move
backwards when starting from a standstill.
When this occurs, you can use the parking
brake switch in the same way as a conven-
tional lever type parking brake.
Before starting on sloping roads when tow-
ing a trailer, be sure to read the following to
prevent the vehicle from moving backwards
unintentionally.
∙ Release the parking brake switch as soon as the engine is delivering enough torque
to the wheels. The automatic brake hold function maintains
the braking force without the driver having to
depress the brake pedal when the vehicle is
stopped at a traffic light or intersection. As
soon as the driver depresses the accelerator
pedal again, the automatic brake hold func-
tion is deactivated and the braking force is
released. The operating status of the auto-
matic brake hold can be displayed on the
vehicle information display.
WARNING
∙ The automatic brake hold function is not
designed to hold the vehicle on a steep hill
or slippery road. Never use the automatic
brake hold when the vehicle is stopped on
a steep hill or slippery road. Failure to do
so may cause the vehicle to move.
∙ When the automatic brake hold function is activated but fails to maintain the ve-
hicle at a standstill, depress the brake
pedal to stop the vehicle. If the vehicle
unexpectedly moves due to outside con-
ditions, the chime may sound and auto-
matic brake hold warning may illuminate
in the vehicle information display.
∙ Be sure to deactivate the automatic brake hold function when using a car
wash or towing your vehicle.
