2021 HYUNDAI TUCSON Brake

5-42
Driving your vehicle
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.
Good Braking Practices
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.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.
NOTICE
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.
WARNING
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.
WARNING

5-44
Driving your vehicle
Do not drive in water if the level
is higher than the bottom of the
vehicle.
Check your brake condition
once you are out of mud or
water. Depress the brake pedal
several times as you move slow-
ly until you feel normal braking
return.
Shorten your scheduled mainte-
nance interval if you drive in off-
road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage
Conditions" in chapter 7).
Always wash your vehicle thor-
oughly after off road use, espe-
cially the bottom of the vehicle.
Be sure to equip the vehicle with
four tires of the same size and
type.
Make sure that a full time AWD
vehicle is towed by a flat bed
tow truck.
NOTICEIn the event your vehicle
leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.

5-46
Driving your vehicle
Maintain AWD Auto mode when
driving on roads in normal con-
ditions.
When driving under normal road
conditions (especially when cor-
nering) in AWD Lock mode, a
driver may find minor mechani-
cal vibration or noise, which is
extremely normal phenomenon,
not a malfunction. When AWD
Lock mode is released, such
noise or vibration will be imme-
diately gone.When driving on normal roads,
deactivate the AWD LOCK mode
by pushing the AWD LOCK button
(AWD LOCK indicator light goes
off). Driving on normal roads with
the AWD LOCK mode, especially,
when cornering may cause
mechanical noise or vibration. The
noise and vibration will disappear
when the AWD LOCK mode is
deactivated. Prolong driving with
the noise and vibration may dam-
age some parts of the power train.
Information
When the AWD LOCK mode is deac-
tivated, a sensation may be felt as the
driving power is delivered entirely to
the front wheels.
For safe AWD operation
Before driving
Make sure all passengers are
wearing seat belts.
Sit upright and closer to the steer-
ing wheel than usual. Adjust the
steering wheel to a position com-
fortable for you to drive.
Driving on snow-covered or icy
roads
Start off slowly by applying the
accelerator pedal gently.
Use snow tires or tire chains.
Keep sufficient distance between
your vehicle and the vehicle in front
of you.
Apply engine braking during decel-
eration by switching the gear shift
lever to Manual Shift Mode and
manually selecting a lower gear.
Avoid speeding, rapid acceleration,
sudden brake applications, and
sharp turns to prevent skids.

Driving in sand or mud
Maintain slow and constant speed.
Use tire chains driving in mud if
necessary.
Keep sufficient distance between
your vehicle and the vehicle in front
of you.
Reduce vehicle speed and always
check the road condition.
Avoid speeding, rapid acceleration,
sudden brake applications, and
sharp turns to prevent getting
stuck.
Driving up or down hills
Driving uphill
- Before starting off, check if it is
possible to drive uphill.
- Drive as straight as possible.
Driving downhill
- Do not change gear while driving
downhill. Select gear before driv-
ing downhill.
- Drive slowly using engine braking
while driving downhill.
- Drive straight as possible.
OLMB053017
Exercise extreme caution when
driving up or down steep hills.
The vehicle may flip over
depending on the grade, the ter-
rain, and the trail conditions.
WARNING
When the vehicle is stuck in
snow, sand or mud, place a non-
slip material under the drive
wheels to provide traction OR
Slowly spin the wheels in for-
ward and reverse directions
which causes a rocking motion
that may free the vehicle.
However, avoid running the
engine continuously at high
rpm, doing so may damage the
AWD system.
CAUTION

5-50
Driving your vehicle
A full-time AWD vehicle should not
be tested on a 2WD roll tester. If a
2WD roll tester must be used, per-
form the following procedure:
1. Check the tire pressures recom-
mended for your vehicle.
2. Place the front wheels on the roll
tester for a speedometer test as
shown in the illustration.
3. Release the parking brake.
4. Place the rear wheels on the tem-
porary free roller as shown in the
illustration.
OTLE058117Roll Tester (Speedometer)
Temporary Free Roller
Never engage the parking
brake while performing the
test.
When the vehicle is lifted up,
do not operate the front and
rear wheel separately. All four
wheels should be operated.
CAUTION
Keep away from the front of the
vehicle while the vehicle is in
gear on the dynamometer. The
vehicle can jump forward and
cause serious injury or death.

FCA Warning Message and
System Control
The FCA produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, or insufficient braking dis-
tance detection. Also, it controls the
brakes in accordance with the colli-
sion risk levels.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward
Collision Warning include Late,
Normal or Early initial warning time.
Collision Warning
(First warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs to help
decelerate the vehicle.
- Your vehicle speed may deceler-
ate moderately.
- The FCA system limitedly con-
trols the brakes to preemptively
mitigate impact in a collision.
Emergency braking
(Second warning)
This warning message appears on
the LCD display with a warning
chime.
Additionally, some vehicle system
intervention occurs to help deceler-
ate the vehicle.
- The FCA system limitedly con-
trols the brakes to preemptively
mitigate impact in a collision. The
brake control is maximized just
before a collision.

Driving your vehicle
Brake operation
The braking system enters into the
ready status to react promptly to
urgent situations.
The FCA provides additional brak-
ing power for optimum braking per-
formance, when the driver depress-
es the brake pedal.
The braking control is automatical-
ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The FCA brake control is automat-
ically canceled, when risk factors
disappear.
The driver should always use
extreme caution while operat-
ing the vehicle, whether or not
there is a warning message or
alarm from the FCA system.
If any other warning sound
such as seat belt warning
chime is already generated,
the Forward Collision-
Avoidance Assist (FCA) sys-
tem warning may not sound.
CAUTION
The braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility
to safely drive and control the
vehicle.
WARNING
The FCA system logic operates
within certain parameters, such
as the distance from the vehicle
ahead, the speed of the vehicle
ahead, and the driver's vehicle
speed. Certain conditions such
as inclement weather and road
conditions may affect the oper-
ation of the FCA system.
WARNING
Never deliberately drive danger-
ously to activate the system.

System Not Operating
Check Forward Collision Avoidance
Assist system
When the FCA is not working prop-
erly, the FCA warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, the master warning light
( ) will illuminate. In this case,
have the vehicle inspected by an
authorized HYUNDAI dealer.
The FCA warning message may
appear along with the illumination
of the ESC (Electronic Stability
Control) warning light and the FCA
is automatically deactivated.
OIK057091L
Even if there is any problem
with the brake control function
of the FCA system, the vehi-
cle's basic braking perform-
ance will operate normally.
However, brake control func-
tion for avoiding collision will
not activate.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
The FCA system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The FCA system may not acti-
vate if the driver applies the
brake pedal to avoid a colli-
sion.
The brake control may not
work, possibly causing a colli-
sion, if a vehicle in front
abruptly stops. Always pay
extreme caution.
The FCA is only a supplemen-
tal system for the driver's con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the FCA
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed.
In certain instances and
under certain driving condi-
tions, the FCA system may
unintentionally activate. This
initial warning message
appears on the LCD display
with a warning chime.
Also, in certain instances the
front camera recognition sys-
tem may not detect the vehi-
cle ahead. The FCA system
may not activate and the
warning message will not be
displayed.
