Power Brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the vehicle is not in the ready
( ) mode or the vehicle is turned
off while driving, the power assist for
the brakes will not work. You can still
stop your vehicle by applying greater
force to the brake pedal than typical.
The stopping distance, however, will
be longer than with power brakes.
When the vehicle is not in the ready
( ) mode, the reserve brake
power is partially depleted each time
the brake pedal is applied. Do not
pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.

Take the following precautions:
Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
When descending down a
long or steep hill, use the pad-
dle shifter (left side lever) to
increase regenerative braking
control in order to control
your speed without using the
brake pedal excessively.
Applying the brakes continu-
ously will cause the brakes to
overheat and could result in a
temporary loss of braking per-
formance.
(Continued)
(Continued)
Wet brakes may impair the
vehicle's ability to safely slow
down; the vehicle may also
pull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heat
up the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.
