Get Driving Your Vehicle -> Braking System Guide for Hyundai Tucson SUV 2020

BRAKING SYSTEM

Power Brakes

Your vehicle has power-assisted

brakes that adjust automatically

through normal usage.

• 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.

WARNING

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, move the

gear shift lever 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 tempo-

rary loss of braking perform-

ance.

If the engine is not running or 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 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.

5

Pump the brake pedal only when

necessary to maintain steering con-

trol on slippery surfaces.

WARNING

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.

To reduce the risk of SERIOUS

INJURY or DEATH, do not oper-

ate the parking brake while the

vehicle is moving except in an

emergency situation. It could

damage the brake system and

lead to an accident.

5-33

Driving your vehicle

ABS cannot prevent a loss of stabili-

ty. Always steer moderately when

braking hard. Severe or sharp steer-

ing wheel movement can still cause

your vehicle to veer into oncoming

traffic or off the road.

On loose or uneven road surfaces,

operation of the anti-lock brake sys-

tem may result in a longer stopping

distance than for vehicles equipped

with a conventional brake system.

Using ABS

• Drive your vehicle at reduced

speeds during the following

conditions:

• Rough, gravel or snow-cov-

ered roads.

• On roads where the road sur-

face is pitted or has different

surface height.

• Tire chains are installed on

your vehicle.

The safety features of an ABS

or ESC equipped vehicle should

not be tested by high speed

driving or cornering. This could

endanger the safety of yourself

or others.

To obtain the maximum benefit from

your ABS in an emergency situation,

do not attempt to modulate your

brake pressure and do not try to

pump your brakes. Depress your

brake pedal as hard as possible.

When you apply your brakes under

conditions which may lock the

wheels, you may hear sounds from

the brakes, or feel a corresponding

sensation in the brake pedal. This is

normal and it means your ABS is

active.

ABS does not reduce the time or dis-

tance it takes to stop the vehicle.

Always maintain a safe distance from

the vehicle in front of you.

ABS will not prevent a skid that

results from sudden changes in

direction, such as trying to take a

corner too fast or making a sudden

lane change. Always drive at a safe

speed for the road and weather con-

ditions.

The ABS warning light (

) will stay

on for several seconds after the igni-

tion switch is in the ON position.

During that time, the ABS will go

through self-diagnosis and the light

will go off if everything is normal. If

the light stays on, you may have a

problem with your ABS. Contact an

authorized HYUNDAI dealer as soon

as possible

ABS is an electronic braking system

that helps prevent a braking skid.

ABS allows the driver to steer and

brake at the same time.

The Electronic Stability Control

(ESC) system helps to stabilize the

vehicle during cornering maneuvers.

ESC checks where you are steering

and where the vehicle is actually

going. ESC applies braking pressure

to any one of the vehicle’s brakes

and intervenes in the engine man-

agement system to assist the driver

with keeping the vehicle on the

intended path. It is not a substitute

for safe driving practices. Always

adjust your speed and driving to the

road conditions.

i

Information

When you jump start your vehicle

because of a drained battery, the ABS

warning light (

) may turn on at the

same time. This happens because of

the low battery voltage. It does not

mean your ABS is malfunctioning.

Have the battery recharged before

driving the vehicle.

tions allow. See "Cruise Control

System" later in this chapter. (if

equipped)

• When moving out of the mud or

driving on a slippery road, the

engine RPM (revolutions per

minute) may not increase even if

you press the accelerator pedal

deeply. This is to maintain the sta-

bility and traction of the vehicle and

does not indicate a problem.

WARNING

Never drive too fast for the road

conditions or too quickly when

cornering. The ESC system will

not prevent accidents.

Excessive speed in turns, abrupt

maneuvers, and hydroplaning

on wet surfaces can result in

severe accidents.

When operating

Driving your vehicle

To dry the brakes, apply the brakes

lightly until the braking action returns

to normal, taking care to keep the

vehicle under control at all times. If

the braking action does not return to

normal, stop as soon as it is safe to

do so and call an authorized

HYUNDAI dealer for assistance.

DO NOT drive with your foot resting

on the brake pedal. Even light, but

constant pedal pressure can result in

the brakes overheating, brake wear,

and possibly even brake failure.

If a tire goes flat while you are driv-

ing, apply the brakes gently and

keep the vehicle pointed straight

ahead while you slow down. When

you are moving slowly enough for it

to be safe to do so, pull off the road

and stop in a safe location.

Keep your foot firmly on the brake

pedal when the vehicle is stopped to

prevent the vehicle from rolling for-

ward.

Good Braking Practices

WARNING

If the DBC red indicator light

illuminates, the system may

have overheated or have mal-

functioned. When the warning

light illuminates even though

the DBC system has cooled off,

have your vehicle checked by

an authorized HYUNDAI dealer

as soon as possible.

Whenever leaving the vehicle or

parking, always come to a com-

plete stop and continue to

depress the brake pedal. Move

the shift lever into the P (Park)

position, then apply the parking

brake, and place the ignition

switch in the OFF position.

Vehicles parked with the park-

ing brake not applied or not

fully engaged may roll inadver-

tently and may cause injury to

the driver and others. ALWAYS

apply the parking brake before

exiting the vehicle.

NOTICE

• The DBC may not deactivate on

steep inclines even though the

brake or accelerator pedal is

depressed.

• The DBC does not operate

when:

- The shift lever is in P (Park).

- The ESC is activated.

Wet brakes can be dangerous! The

brakes may get wet if the vehicle is

driven through standing water or if it

is washed. Your vehicle will not stop

as quickly if the brakes are wet. Wet

brakes may cause the vehicle to pull

to one side.
