Anti-lock brake system (ABS)
• Driving on bumpy roads or other poor
driving surfaces.
You will hear the operation sound of the
motor coming from the Plug-in Hybrid
EV System compartment immediately
following start off after starting the Plug-
in Hybrid EV System. If the brake pedal
is depressed at that moment, you can
feel the brake pedal pulsating.
This pulsation is due to the self-diagno-
sis operation of the ABS and does not
indicate a malfunction.
The ABS will operate after the vehicle
has accelerated to a speed in excess of
approximately 10 km/h (6 mph). It stops
operating when the vehicle decelerates
to a speed below about 5 km/h (3 mph).

Anti-lock brake system
(ABS)
Operation of ABS is not restricted to sit-
uations where brakes are applied sud-
denly. This system may also operate to
prevent wheel lock when you are driving
over manholes, steel road-work plates,
or the vehicle is driven over steps or lev-
el differences in the road, road markings,
or other surfaces which are difficult for
the wheels to grip.
When the ABS is activated, you may
feel the brake pedal pulsation and the vi-
brations of the vehicle body and steering
wheel. You may also hear a characteris-
tic noise. At this time, you may feel as if
the pedal attempts to resist being de-
pressed.
This is a normal result of the ABS oper-
ation, and does not indicate a problem.
If this situation occurs, depress the
brake pedal more firmly in order to
operate the ABS. Do not pump the
brake. This will result in reduced
braking performance.

Environmental conditions can have an effect
on braking. During sudden braking when
there is snow, ice, oil, water etc. on the road
surface, a skid may occur. In this situation,
steering control and braking effectiveness is
reduced and the stopping distance is in-
creased. The vehicle may also go into an un-
controlled spin.
The ABS helps prevent the wheels from lock-
ing during braking, thus maintaining direc-
tional stability, ensuring controllability and
providing optimum braking force.

CAUTION
Operating hints
Even the ABS cannot prevent the natural
laws of physics from acting on the vehicle. It
cannot for instance avoid accidents that may
result from excessive speed on bends or fol-
lowing another vehicle too closely or aqua-
planing. It should remain the driver’s task to
observe safety precautions to judge speeds
and brake applications correctly in such con-
ditions.
Be sure to use tyres of the same type and
size on 4 wheels.
If tyre types or sizes are mixed, ABS may
not function normally.
Always maintain the same distance from
the vehicle in front of you as you would
for a vehicle not equipped with ABS.
Compared with vehicles not fitted with
ABS, your vehicle may require a longer
stopping distance in the following cases:
• Driving on gravel or snow-covered
roads.
l
• Driving with snow traction device
(tyre chains) installed.
• Driving on roads where the road sur-
face is pitted or has other differences
in surface height.
