Stopping the hybrid system

WARNING

If you want to stop the hybrid system in an emergency while driving the vehicle, press
and hold the power switch for more than 2 seconds, or press it briefly 3 times or more in
succession.
However, do not touch the power switch while driving, except in an emergency. Turning
the hybrid system off while driving will not cause loss of steering or braking control,
however power assist to the steering will be lost. This will make it more difficult to steer.
Pull over and stop the vehicle as soon as it is safe to do so.

Stop the vehicle completely.

Press the P position switch.

Check that the shift position indicator shows P and the parking brake indicator is
illuminated.

Press the power switch.

The hybrid system will stop, and the meter display will be extinguished (the shift position
indicator will be extinguished a few seconds after the meter display).

Release the brake pedal and check that the display on the instrument cluster is
off.

WARNING

■

When driving the vehicle

●

If the vehicle is coasting due to the hybrid system being stopped, etc., do not operate
the door locks or open a door until the vehicle has been safely stopped. Doing so may
cause the steering lock function to operate, possibly leading to an accident.

●

When backing up, you may twist your body around, leading to difficulty in operating
the pedals.
Make sure to operate the pedals properly.

●

Make sure to keep a correct driving posture even when moving the vehicle only
slightly. This allows you to depress the brake and accelerator pedals properly.

●

Depress the brake pedal using your right foot.
Depressing the brake pedal using your left foot may delay response in an emergency,
resulting in an accident.

●

Do not drive the vehicle over or stop the vehicle near flammable materials. The
exhaust system and exhaust gases can be extremely hot. These hot parts may cause a
fire if there is any flammable material nearby.

●

Never turn the power switch off during normal driving. If the hybrid system is stopped
while driving, steering and brake operations will still be possible, however, power assist
will no longer be provided and the steering wheel will become difficult to operate.
After checking the safety of the area around your vehicle, stop the vehicle on the side
of the road. In an emergency, if the vehicle cannot be stopped normally, perform an
emergency stop.

●

Use engine braking (downshift) to maintain a safe speed when driving down a steep
hill. Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness.

●

Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear
view mirrors while driving. Doing so may result in a loss of vehicle control.

●

Always check that all passengers’ arms, heads or other parts of their body are not
outside the vehicle.

●

This vehicle is not designed for extreme off-roading.

•

When driving in sand or mud is unavoidable, drive carefully and avoid continuous
driving on sand or mud.

•

Do not drive on extremely rocky roads or extremely uneven roads.

●

Do not drive across a river or through other bodies of water. This may cause elec-
tric/electronic components to short circuit, damage the hybrid system or cause other
serious damage to the vehicle.

2-2. Driving procedures

188

WARNING

●

Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do
not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability tires.
Driving over 85 mph (140 km/h) may result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle
are high-speed capability tires or not before driving at such speeds.

●

Avoid sudden braking, acceleration, and steering inputs when driving on slick road
surfaces. Doing so may cause the tires to lose traction, leading to loss of control of the
vehicle.

●

Avoid sudden accelerator pedal operations and shift operations when driving on slick
road surfaces.Doing so may cause engine braking or changes in engine speed may
cause the vehicle to slide sideways.

●

After driving through a puddle, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on only one side are wet and not functioning
properly, steering control may be affected.

●

When driving in sand or mud is unavoidable, drive carefully and avoid continuous
driving on sand or mud.
Do not drive on extremely rocky roads or extremely uneven roads.

■

If you hear a squealing or scraping noise (brake pad wear limit indicators)

Have the brake pads checked and replaced by your Lexus dealer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those of
the brake discs are exceeded.

NOTICE

■

Avoiding damage to vehicle parts

●

Do not turn and hold the steering wheel at either fully turned position for an extended
period of time. Doing so may damage the power steering motor.

●

When driving over bumps or areas where the road height changes, drive as slowly as
possible. Otherwise the wheels, etc. may be damaged.

■

If you get a flat tire while driving

In the following situations, firmly hold the steering wheel and gradually apply the brakes
to decrease the vehicle’s speed, as a tire may be flat or damaged:

●

When the steering wheel pulls either direction

●
