2019 LEXUS UX250H brake

661-4. Hybrid system
*: AWD models only
■Running out of fuel
When the vehicle has run out of fuel and the
hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to
make the low fuel level warning light
(  P.390) go off. If th ere is only a small
amount of fuel, the hybrid system may not
be able to start. (The standard amount of
fuel is about 1.8 gal. [7.0 L, 1.5 Imp.gal.],
when the vehicle is on a level surface. This
value may vary when the vehicle is on a
slope. Add extra fuel when the vehicle is
inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid
vehicles incorporate electromagnetic
shielding, and ther efore emit approxi-
mately the same amount of electromag-
netic waves as conventional gasoline
powered vehicles or home electronic
appliances.
●Your vehicle may cause sound interfer-
ence in some third party-produced radio
parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a
limited service life. The lifespan of the
hybrid battery (traction battery) can
change in accordance with driving style and
driving conditions.
WARNING
■High voltage precautions
This vehicle has high voltage DC and AC
systems as well as a 12-volt system. DC
and AC high voltage is very dangerous
and can cause severe burns and electric
shock that may result in death or serious
injury.
●Never touch, disassemble, remove or
replace the high voltage parts, cables
or their connectors.
●The hybrid system will become hot
after starting as the system uses high
voltage. Be careful of both the high
voltage and the high temperature, and
always obey the warning labels
attached to the vehicle.
●Never try to open the service plug
access hole located underneath the
rear seats. The service plug is used
only when the vehicle is serviced and is
subject to high voltage.
■Road accident cautions
Observe the following precautions to
reduce the risk of death or serious injury:
●Pull your vehicle off the road, shift the
shift lever to P, apply the parking brake,
and turn the hybrid system off.
●Do not touch the high voltage parts,
cables and connectors.
●If electric wires are exposed inside or
outside your vehicle, an electric shock
may occur. Never touch exposed elec-
tric wires.
●If a fluid leak occurs, do not touch the
fluid as it may be st rong alkaline elec-
trolyte from the hybrid battery (trac-
tion battery). If it comes into contact
with your skin or eyes, wash it off
immediately with a large amount of
water or, if possible, boric acid solu-
tion. Seek immediate medical atten-
tion.

4-1.Before driving
■Starting the hybrid system
 P.162
■Driving
1 With the brake pedal depressed,
shift the shift lever to D. ( P.167)
2 If the parking brake is in manual
mode, release the parking brake.
(P.172)
3 Gradually release the brake pedal
and gently depress the accelerator
pedal to accelerate the vehicle.
■Stopping
1 With the shift lever in D, depress the
brake pedal.
2 If necessary, set the parking brake.
(P.172)
If the vehicle is to be stopped for an
extended period of time, shift the shift lever
to P. ( P.167)
■Parking the vehicle
1 With the shift lever in D, depress the
brake pedal.
2 If the parking brake is in manual
mode, set the parking brake
(P.172), and shift the shift lever to
P ( P.167).
3 Press the power switch to stop the
hybrid system. 4
Lock the door, making sure that you
have the electronic key on your
person.
If parking on a hill, block the wheels as
needed.
■Starting off on a steep uphill
1 Make sure that the parking brake is
set with the brake pedal depressed,
and then shift the shift lever to D.
2 Release the brake pedal and gently
depress the accelerator pedal.
3 Release the parking brake.
■When starting off on a uphill
The hill-start assist control will be activated.
(  P.257)
■For fuel-efficient driving
Keep in mind that hybr id vehicles are similar
to conventional vehicles, and it is necessary
to refrain from activi ties such as sudden
acceleration. ( P.261)
■Driving in the rain
●Drive carefully when it is raining, because
visibility will be reduced, the windows
may become fogged-up, and the road
will be slippery.
●Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
●Refrain from high speeds when driving on
an expressway in the rain, because there
may be a layer of wa ter between the tires
and the road surface, preventing the
steering and brakes from operating prop-
erly.
■Restraining the hybrid system output
(Brake Override System)
●When the accelerato r and brake pedals
are depressed at the same time, the
hybrid system output may be restrained.
●A warning message is displayed on the
multi-information display and head-up
display (if equipped) while the system is
operating. ( P.391)
Driving the vehicle
The specified procedures should be
observed to ensure safe driving:
