Good Driving Practices
• Never shift the gear from P (Park) or
N (Neutral) to any other position with
the accelerator pedal depressed.
• Never shift the gear into P (Park) when
the vehicle is in motion.
• Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive). •
Do not shift the gear to N (Neutral)
when driving. Doing so may result
in an accident because of a loss of
engine braking and the transmission
could be damaged.
• Driving uphill or downhill, always shift
to D (Drive) when driving forward or to
R (Reverse) when driving backwards,
and check the gear position indicated
on the cluster before driving. If you
drive in the opposite direction of the
selected gear, the engine will turn
off and a serious accident might be
occurred due to the degraded brake
performance.
• Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can result
in the brakes overheating, brake wear
and possibly even brake failure.
• When driving in the manual shift
mode, slow down before shifting to a
lower gear. Otherwise, the lower gear
may not be engaged if the engine
rpms are outside of the allowable
range.
• Always apply the parking brake when
leaving the vehicle. Do not depend on
placing the transmission in P (Park) to
keep the vehicle from moving.
• Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the drive
wheels to lose traction and may cause
loss of vehicle control resulting in an
accident
• Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator.

BRAKE SYSTEM
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.
WARNING
Take the following precautions:
• Do not drive with your foot resting
on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances.
• When descending down a long or
steep hill, move the gear shift button
to Manual Shift Mode and manually
downshift to a lower gear in order
to control your speed without using
the brake pedal excessively. Applying
the brakes continuously will cause
the brakes to overheat and could
result in a temporary loss of braking
performance.
• 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 fashion after driving
through deep water. To dry the
brakes, lightly tap the brake pedal to
heat up the brakes while maintaining
a safe forward speed until brake
performance returns to normal.
Avoid driving at high speeds until the
brakes function correctly.
NOTICE
• Do not continue depressing the
brake pedal if the "" indicator is OFF. The battery may be discharged.
• Noise and vibration generated
during braking is normal.
• Under normal operation, electric
brake pump noise and motor
vibration may occur temporarily in
below cases.
-When the pedal is depressed
suddenly.
-When the pedal is repeatedly
depressed in short intervals.
-When the ABS function is activated
while braking.

Disc Brakes Wear Indicator
When your brake pads are worn and new
pads are required, you will hear a high
pitched warning sound from your front
or rear brakes. You may hear this sound
come and go or it may occur whenever
you depress the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does not
indicate a problem with your brakes.
NOTICE
To avoid costly brake repairs, do not
continue to drive with worn brake pads.
Information
Always replace brake pads as complete
front or rear axle sets.
