Driving Your Vehicle6-18
Power Brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event of a vehicle power failure,
the power assist for the brakes will not
work. You can still stop your vehicle, but
it will require greater force and increased
pedal travel than normal. The stopping
distance, however, will be longer than
with power brakes.
Information

[ When the brake pedal is depressed
under certain driving conditions
or weather conditions, you may
temporarily hear a noise. This is
normal and does not indicate a problem
with your brakes.

[ While driving on a road with deicing
chemicals, brake noise or abnormal
tire wear may occur due to deicing
chemicals. In a safe traffic condition,
additionally apply the brakes to remove
deicing chemicals on the brake discs
and pads.
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 repeatedly
depressed in short intervals.
- When the ABS function is activated
while braking.

Winter Precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 9. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked
by an authorized HYUNDAI dealer or in a
service station.
If the vehicle is not used for a long time,
park the vehicle indoors if possible.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not sure
about a type of winter weight oil, consult
an authorized HYUNDAI dealer.Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 9. If necessary, replace them.
Also check all ignition wirings and
components for any cracks, wear-out,
and damage.
To prevent locks from freezing
To prevent the locks from being frozen,
spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes,
try to thaw it with a heated key. Carefully
use the heated key to avoid an injury.
Use approved window washer anti-
freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized HYUNDAI
dealer, and most vehicle accessory
outlets. Do not use engine coolant or
other types of anti-freeze solution, to
prevent any damage to the vehicle paint.

Emergency Situations8-10
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Shift the gear to P (Park) and set the parking brake
3. Turn off the air conditioner.
4. When the coolant or hot steams gush out of the reservoir, stop the engine
and call an authorized HYUNDAI
dealer for assistance. If the coolant
does not flow out, leave the engine
compartment opened, while running
the engine. Check the coolant
temperature gauge on the instrument
cluster and turn off the engine to
make sure the coolant temperature is
sufficiently cooled down. 5. Cool down the engine sufficiently
and check the coolant level. When it
is insufficient, check its connection
with the radiator, the heater hose,
and the water pump for any leakage.
When there is no leakage, add the
coolant. However, if the problems
persists, such as the coolant leakages,
the cooling-fan malfunction or the
water pump drive belt damages,
immediately stop the engine, and
have your vehicle checked by an
authorized HYUNDAI dealer.

[ You should mix antifreeze and water in
a proper ratio to make coolant. If the
antifreeze ratio is too high or low, it
may cause overheating due to the lack
of cooling function.
(Refer to the Mix Ratio in “Checking
the coolant level” in chapter 8.)

[ If overheating happens repeatedly,
have your vehicle to be checked by an
authorized HYUNDAI dealer.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury.
