If the brake fluid level in the reser-
voir is low:
1. Drive carefully to the nearest safelocation and stop your vehicle.
2. With the vehicle turned off, 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 compo-
nents 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 you to
have the vehicle inspected by an
authorized 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 is
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 while you are driv- ing, use the paddle shifter (left side
lever) to increase regenerative brak-
ing control and stop the vehicle as
soon as it is safe to do so.
Regenerative Brake
Warning Light
This warning light illuminates :
When the regenerative brake does
not operate and the brake does not
perform well. This causes the Brake
Warning light (red) and Regenerative
Brake Warning Light (yellow) to illu-
minate simultaneously.
In this case, drive safely and we rec-
ommend that you have your vehicle
inspected by an authorized HYUNDAI
dealer.
The operation of the brake pedal may
be more difficult than normal and the
braking distance can increase.
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, itindicates that the brake fluid
level is low.
In this case, we recommend
that you have the vehicle
inspected by an authorized
HYUNDAI dealer.

Check battery and cables
The winter temperature increases
the battery consumption.Inspect
the battery and cables, as speci-
fied in the chapter 7. The battery
charging level can be checked by an
authorized HYUNDAI dealer or in a
service station.
Change to "winter weight" oil if
necessary
In some regions during winter, it is recommended to use the "winter
weight" oil with lower viscosity. For
further information, refer to the chap-
ter 8. When you are not sure about a
type of winter weight oil, consult an
authorized HYUNDAI dealer. 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 spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorized
HYUNDAI dealer, and so are the
most vehicle accessory outlets. Donot use coolant or other types of anti-
freeze solution to prevent any dam-
age to the vehicle paint.Do not let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. When
there is the risk that your parking
brake may freeze, temporarily shift to
P (Park). Also, block the rear wheels
in advance, so the vehicle may not
roll. Then, release the parking brake.
Do not let ice and snow accumu- late underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in such conditions during the
severe winter, you should check
underneath the vehicle on a regular
basis, so that moving the front
wheels and the steering components
is unblocked.

What to do in an emergency
1. Pull off the road and stop as soonas it is safe to do so.
2. Shift to P (Park) and set the park- ing brake. If the air conditioning is
on, turn it off.
3. If coolant is running out under the vehicle or steam is coming out
from the hood, stop the vehicle.Do not open the hood until the
coolant has stopped running or
the steaming has stopped. If there
is no visible loss of coolant and no
steam, leave the vehicle running
and check to be sure the cooling
fan is operating. If the fan is not
running, turn the vehicle off.
4. Check for coolant leaking from the radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop). 5. If coolant is leaking out, turn off
the vehicle immediately and we
recommend that you call an
authorized HYUNDAI dealer for
assistance.
6. If you cannot find the cause of the overheating, wait until the radiator
temperature has returned to nor-
mal. Then, if coolant has beenlost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark. 7. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call an
authorized HYUNDAI dealer for
assistance.
• Serious loss of coolant indi- cates there is a leak in the cool-ing system and we recommend
that the system be checked by
an authorized HYUNDAI dealer.
When overheating from low coolant, suddenly adding coolant
may cause damages in the motor
compartments. To prevent dam-
age, add coolant slowly in smallquantities.
NOTICE
IIFF TT HH EE VV EEHH IICC LLEE OO VVEERR HH EEAA TTSS
Do not remove the coolant cap
when the radiator is hot. This
can allow coolant to blow out ofthe opening and cause serious
burns.

What to do in an emergency
Emergency towing
If towing is necessary, we recom-
mend you have it done by an author-
ized HYUNDAI dealer or a commer-
cial tow truck service.
If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-ing hook at the front (or rear) of the
vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a
short distance and at low speeds.
Also, the wheels, axles, power train,
steering and brakes must all be ingood condition.Always follow these emergency tow-ing precautions:
While depressing the brake pedal
shift to the N (Neutral) position and
turn the vehicle off. The POWER
button will be in the ACC position.
Release the parking brake.
Depress the brake pedal with more force than normal since you will
have reduced braking perform-
ance.
More steering effort will be required because the power steering system
will be disabled.
Use a vehicle heavier than your own to tow your vehicle.
The drivers of both vehicles should communicate with each other fre-
quently.
Before emergency towing, check that the hook is not broken or dam-aged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply steady and even force. Use a towing cable or chain less
than 5 m (16 feet) long. Attach awhite or red cloth (about 30 cm (12inches) wide) in the middle of the
cable or chain for easy visibility.
Drive carefully so the towing cable or chain remains tight during tow-ing.
Before towing, check the reduction gear for fluid leaks under your vehi-
cle. If the reduction gear fluid is
leaking, flatbed equipment or a tow-
ing dolly must be used.
