2015 Hyundai Sonata brakes

VEHICLE RUN-IN PROCESS
F10
Introduction
No special run-in period is needed.
By following a few simple precautions
for the first 1,000 km you may add to
the performance, economy and life of
your vehicle.
• Do not race the engine.
• Whilst driving, keep your engine
speed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 rpm.
• Do not maintain a single speed for
long periods of time, either fast or
slow. Varying engine speed is need-
ed to properly run-in the engine.
• Avoid hard stops, except in emer-
gencies, to allow the brakes to seat
properly.
• Do not tow a trailer during the first
2,000 km of operation.

Parking Brake & Brake
Fluid Warning Light
This warning light illuminates:
• Once you set the ignition switch or
the Engine Start/Stop button to the
ON position.
- It illuminates for approximately 3
seconds
- It remains on if the parking brake
is applied.
• When the parking brake is applied.
• When the brake fluid level in the
reservoir is low.
- If the warning light illuminates
with the parking brake released, it
indicates the brake fluid level in
reservoir is low.
If the brake fluid level in the reser-
voir is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the
brake fluid level immediately and
add fluid as required (For more
details, refer to “Brake Fluid” in
chapter 7). Then check all brake
components for fluid leaks. If any
leak in the brake system is still
found, the warning light remains
on, or the brakes do not operate
properly, do not drive the vehicle.
In this case, we recommend that
you have the vehicle towed to an
authorised HYUNDAI dealer and
inspected.
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems should fail.
With only one of the dual systems
working, more than normal pedal
travel and greater pedal pressure are
required to stop the vehicle.
Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
If the brakes fail whilst you are driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.

When you shift into the R (Reverse)
position and one or more of the
below situations occur, this may indi-
cate a malfunction with the parking
assist system.
• You don't hear an audible warning
sound or the buzzer sounds inter-
mittently.
If this occurs, we recommend that
the system be checked by an autho-
rised HYUNDAI dealer.
Non-operational conditions of
rear parking assist system
The rear parking assist system
may not operate normally when:
• Moisture is frozen to the sensor.
• The sensor is covered or stained
with foreign material, such as snow
or water, or the sensor cover is
blocked.There is a possibility of a parking
assist system malfunction when:
• Driving on uneven road surfaces
such as unpaved roads, gravel,
bumps, or gradients.
• Objects generating excessive noise
such as vehicle horns, loud motor-
cycle engines, or truck air brakes
can interfere with the sensor.
• Heavy rain or water spray is present.
• Wireless transmitters or mobile
phones are present near the sensor.
• The sensor is covered with snow.
• Any non-factory equipment or
accessories have been installed, or
if the vehicle bumper height or sen-
sor installation has been modified.
• Trailer towing.Detecting range may decrease
when:
• Outside air temperature is
extremely hot or cold.
• Undetectable objects smaller than
about 1 m (40 in.) and narrower
than about 14 cm (6 in.) in diameter.
The following objects may not be
recognised by the sensor:
• Sharp or slim objects such as
ropes, chains or small poles.
• Objects, which tend to absorb sen-
sor frequency such as clothes,
spongy material or snow.
• is displayed. (if equipped)
Your new vehicle warranty does
not cover any accidents or dam-
age to the vehicle or injuries to
its occupants due to a rear
parking assist system malfunc-
tion. Always drive safely and
cautiously.

Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake,
and place the ignition switch in the
LOCK/OFF position. Take the key
with you when exiting the vehicle.
Good driving practices
• Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
• Never move the shift lever into P
(Park) when the vehicle is in
motion.
Ensure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).
• Do not move the shift lever to N
(Neutral) when driving. Doing so
may result in an accident because
of a loss of engine braking and the
transaxle could be damaged.
• 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 sports 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 transaxle 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. When you stay in the vehicle
with the engine running, be
careful not to depress the accel-
erator pedal for a long period of
time. The engine or exhaust
system may overheat and start
a fire.
The exhaust gas and the
exhaust system are very hot.
Keep away from the exhaust
system components.
Do not stop or park over flam-
mable materials, such as dry
grass, paper or leaves. They
may ignite and cause a fire.

Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the engine is not running or is
turned off whilst 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 dis-
tance, however, will be longer than
with power brakes.
When the engine is not running, 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.
BRAKING SYSTEM
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 a long or
steep hill, shift to a lower gear
and avoid continuous applica-
tion of the brakes. Applying
the brakes continuously will
cause the brakes to overheat
and could result in a tempo-
rary loss of braking perform-
ance.
(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 whilst maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.
WARNING

Driving your vehicle
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.
Please remember some driving con-
ditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
To avoid costly brake repairs, do
not continue to drive with worn
brake pads.
Information
Always replace brake pads as com-
plete front or rear axle sets.
Parking brake
Applying the parking brake
Foot type
To engage the parking brake, first
apply the foot brake and then
depress the parking brake pedal
down as far as possible.
i
NOTICE
To reduce the risk of SERIOUS
INJURY or DEATH, do not oper-
ate the parking brake whilst the
vehicle is moving except in an
emergency situation. It could
damage the brake system and
lead to an accident.
