Parking Brake & Brake
Fluid Warning Light
This warning light illuminates:
When 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
the 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). After adding brake
fluid, check all brake components
for fluid leaks. If a brake fluid leak is
found, or if the warning light
remains on, or if the brakes do not
operate properly, do not drive the
vehicle. We recommend that you
have the vehicle inspected by an
authorised HYUNDAI dealer.
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.
Parking Brake & Brake Fluid
Warning Light
Driving the vehicle with a warn-
ing light ON is dangerous. If the
Parking Brake & Brake Fluid
Warning Light illuminates with
the parking brake released, it
indicates that the brake fluid
level is low.
In this case, we recommend
that you have the vehicle
inspected by an authorised
HYUNDAI dealer.
WARNING

Convenient features of your vehicle
Anti-lock Brake System
(ABS) Warning Light
This warning light illuminates:
When you set the ignition switch or
the Engine Start/Stop button to the
ON position.
- It illuminates for approximately 3
seconds and then goes off.
When there is a malfunction with
the ABS (The normal braking sys-
tem will still be operational without
the assistance of the anti-lock
brake system).
In this case, we recommend that
you have the vehicle inspected by
an authorised HYUNDAI dealer.
Electronic Brake Force
Distribution (EBD)
System Warning Light
These two warning lights illuminate
at the same time whilst driving:
When the ABS and regular brake
system may not work normally.
In this case, we recommend that
you have the vehicle inspected by
an authorised HYUNDAI dealer.
Electronic Brake Force
Distribution (EBD) System
Warning Light
When both ABS and Parking
Brake & Brake Fluid Warning
Lights are on, the brake system
will not work normally and you
may experience an unexpected
and dangerous situation during
sudden braking.
In this case, avoid high speed
driving and abrupt braking.
We recommend you have the
vehicle inspected by an autho-
rised HYUNDAI dealer as soon
as possible.

Information - Electronic
Brake Force Distribution
(EBD) System Warning Light
When the ABS Warning Light is on or
both ABS and Parking Brake & Brake
Fluid Warning Lights are on, the
speedometer, odometer, or tripmeter
may not work. Also, the EPS Warning
Light may illuminate and the steering
effort may increase or decrease.
In this case, we recommend you have
the vehicle inspected by an authorised
HYUNDAI dealer as soon as possible.Electronic Parking
Brake (EPB) Warning
Light (if equipped)
This warning light illuminates:
When you set the ignition switch or
the Engine Start/Stop button to the
ON position.
- It illuminates for approximately 3
seconds and then goes off.
When there is a malfunction with
the EPB.
In this case, we recommend that
you have the vehicle inspected by
an authorised HYUNDAI dealer.
Information
The Electronic Parking Brake (EPB)
Warning Light may illuminate when
the Electronic Stability control (ESC)
Indicator Light comes on to indicate
that the ESC is not working properly
(This does not indicate malfunction of
the EPB).
AUTO HOLD Indicator
Light (if equipped)
This indicator light illuminates:
[White] When you activate the auto
hold system by pressing the AUTO
HOLD button.
[Green] When you stop the vehicle
completely by depressing the
brake pedal with the auto hold sys-
tem activated.
[Yellow] When there is a malfunc-
tion with the auto hold system.
In this case, we recommend that
you have the vehicle inspected by
an authorised HYUNDAI dealer.
For more details, refer to “Auto
Hold” in chapter 5.

Driving your vehicle
Ready to leave after parking on
a hill
1. With the shift lever in P (Park, for
automatic transmission/dual clutch
transmission vehicle) or neutral (for
manual transmission vehicle),
apply your brakes and hold the
brake pedal down whilst you:

and

2. Slowly remove your foot from the
brake pedal.
3. Drive slowly until the trailer is clear
of the chocks.
4. Stop and have someone pick up
and store the chocks.
Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transmission fluid, axle lubri-
cant and cooling system fluid. Brake
condition is another important item to
frequently check. If you’re towing, it’s
a good idea to review these items
before you start your trip. Don’t forget
to also maintain your trailer and tow-
bar. Follow the maintenance sched-
ule that accompanied your trailer and
check it periodically. Preferably, con-
duct the check at the start of each
day’s driving. Most importantly, all
towbar nuts and bolts should be
tight.To prevent vehicle damage:
Due to higher load during trailer
usage, overheating might occur
on hot days or during uphill driv-
ing. If the coolant gauge indi-
cates over-heating, switch off
the air conditioner and stop the
vehicle in a safe area to cool
down the engine.
Do not switch off the engine
whilst the coolant gauge indi-
cates over-heating.
(Keep the engine idle to cool
down the engine)
When towing check automatic
transmission fluid more fre-
quently.
If your vehicle is not equipped
with an air conditioner, you
should install a condenser fan
to improve engine performance
when towing a trailer.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windscreen washer fluid
level.
Check for low or under-inflated
tyres.
Whilst operating your vehicle:
Note any changes in the sound of
the exhaust or any smell of exhaust
fumes in the vehicle.
Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
Notice if your vehicle constantly turns
slightly or “pulls” to one side when
travelling on smooth, level road.
When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
If any slipping or changes in the
operation of your transmissiom
occurs, check the transmissiom fluid
level.
Check the automatic transmission/
dual clutch transmission P (Park)
function.
Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal). Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
WARNING
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implanted
with the artificial cardiac pace-
maker, should remain away from
the ECU or the wiring harness by
at least 30 cm, whilst running the
diesel engine. The high currents
of the electronic engine control
system produce a considerable
amount of magnetic fields.
