2021 HYUNDAI TUCSON HYBRID warning light

Driving your vehicle
6-4
Before entering the vehicle
• Be sure all windows, outside mirror(s),
and outside lights are clean and
unobstructed.
• Remove frost, snow, or ice.
• Visually check the tires for uneven
wear and damage.
• Check under the vehicle for any sign
of leaks.
• Be sure there are no obstacles behind
you if you intend to back up.
Before starting
• Make sure the hood, the liftgate, and
the doors are securely closed and
locked.
• Adjust the position of the seat and
steering wheel.
• Adjust the inside and side view
mirrors.
• Verify all the lights work.
• Fasten your seat belt. Check that all
passengers have fastened their seat
belts.
• Check the gauges and indicators
in the instrument panel and the
messages on the instrument display
when the ignition switch is in the ON
position.
• Check that any items you are carrying
are stored properly or fastened down
securely.
WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions:
• ALWAYS wear your seat belt. All
passengers must be properly belted
whenever the vehicle is moving.
For more information, refer to “Seat
Belts” section in chapter 3.
• Always drive defensively. Assume
other drivers or pedestrians may be
careless and make mistakes.
• Stay focused on the task of driving.
Driver distraction can cause
accidents.
• Leave plenty of space between you
and the vehicle in front of you.
WARNING
NEVER drink or take drugs and drive.
Drinking or taking drugs and driving
is dangerous and may result in an
accident and SERIOUS INJURY or
DEATH.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Just
one drink can reduce your ability to
respond to changing conditions and
emergencies and your reaction time
gets worse with each additional drink.
Driving while under the influence
of drugs is as dangerous or more
dangerous than driving under the
influence of alcohol.
You are much more likely to have a
serious accident if you drink or take
drugs and drive. If you are drinking or
taking drugs, don’t drive. Do not ride
with a driver who has been drinking
or taking drugs. Choose a designated
driver or call a taxi.

• Driving uphill or downhill, 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 the
vehicle is moving in the opposite
direction of the selected gear, the
engine may stop and a serious
accident may occur. Never attempt
to select a gear that is opposite to the
direction of the vehicle motion.
Stop the vehicle before changing to
the desired gear.
• 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.
• 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.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:
• ALWAYS wear your seat belt. In a
collision, an unbelted occupant
is significantly more likely to be
seriously injured or killed than a
properly belted occupant.
• Avoid high speeds when cornering or
turning. •
Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.
• The risk of rollover is greatly
increased if you lose control of your
vehicle at highway speeds.
• Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.
• In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
• HYUNDAI recommends you follow all
posted speed limits.
WARNING
• Before leaving the driver's seat,
always make sure the shift button
is in the P (Park) position, set the
parking brake, press the Engine
Start/Stop button to the OFF
position, and take the Smart Key with
you.
Unexpected and sudden vehicle
movement can occur if these
precautions are not followed.
• Do not drive with the shift button in
N (Neutral). The engine brake will not
work and may lead to an accident.
• 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.

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, 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 repea

tedly
depressed in short intervals.
- When the ABS function is activa

ted
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.
