stick before checking or draining any lubricant. This is especially impor-
tant in dusty or sandy areas and when the vehicle is used on unpaved
roads. Cleaning the plug and dipstick areas will prevent dirt and grit from
entering the engine and other mechanisms that could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather
operating (engine start and engine oil flowability). Lower viscosity engine oils
can provide better fuel economy and cold weather performance, however, high-
er viscosity engine oils are required for satisfactory lubrication in hot weather.
Using oils of any viscosity other than those recommended could result in engine
damage.
When choosing an oil, consider the range of temperature your vehicle will be
operated in before the next oil change.
Proceed to select the recommended oil viscosity from the chart.

Safety system
SRS warning light
The SRS (Supplement Restraint
System) air bag warning light on the
instrument panel displays the air bag
symbol depicted in the illustration.
The system checks the air bag elec-
trical system for malfunctions. The
light indicates that there is a potential
problem with your air bag system,
which could include your side and/or
curtain air bags used for rollover pro-
tection (if equipped with rollover sen-
sor).
WARNING
If your SRS malfunctions, the air
bag may not inflate properly dur-
ing an accident increasing the risk
of serious injury or death.
If any of the following conditions
occur, your SRS is malfunction-
ing:
‡The light does not turn on for
approximately six seconds when
the ignition switch is in the ON
position.
‡The light stays on after illuminat-
ing for approximately six sec-
onds.
‡The light comes on whilst the
vehicle is in motion.
‡The light blinks when the engine
is running.
We recommend that a HYUNDAI
authorised repairer inspect the
SRS as soon as possible if any of
these conditions occur.During a frontal collision, sensors will
detect the vehicle’s deceleration. If
the rate of deceleration is high
enough, the control unit will inflate the
front air bags, at the time and with the
force needed.
The front air bags help protect the
driver and front passenger by
responding to frontal impacts in which
seat belts alone cannot provide ade-
quate restraint. When needed, the
side air bags help provide protection
in the event of a side impact or roll-
over by supporting the side upper
body area.
‡Air bags are activated (able to
inflate if necessary) only when the
ignition switch is in the ON position.
‡Air bags inflate in the event of cer-
tain frontal or side collisions to help
protect the occupants from serious
physical injury.
‡Generally, air bags are designed to
inflate based upon the severity of a
collision it’s direction etc. These
two factors determine whether the
sensors produce an electronic
deployment/inflation signal.
‡The front air bags will completely
inflate and deflate in an instant. It is
virtually impossible for you to see
the air bags inflate during an acci-
dent. It is much more likely that you
will simply see the deflated air bags
hanging out of their storage com-
partments after the collision.

Parking Brake & Brake
Fluid Warning Light
7his 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 8). 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 that you
have the vehicle inspected by a
HYUNDAI authorised repairer.
'ual-diagonal braking system
Your vehicle is equipped with dual-di-
agonal braking systems. This means
you still have braking on two wheels
even if one of the dual systems 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 additional
engine braking and stop the vehicle
as soon as it is safe to do so.
WARNING
Parking Brake & Brake Fluid
Warning Light
Driving the vehicle with a warning
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
a HYUNDAI authorised repairer.

Whilst driving
WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause uncon-
sciousness and death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by
asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to
change the oil or for any other purpose. If you hear a change in the sound of the
exhaust or if you drive over something that strikes the underneath side of the
vehicle, we recommend that the exhaust system be checked as soon as pos-
sible by a HYUNDAI authorised repairer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a
hazardous practice. Run the engine only long enough to start the engine and to
move the vehicle out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehi-
cle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle, be sure to do so only in an open area with the air intake set at “Fresh”
and fan control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air
intakes located in front of the windscreen clear of snow, ice, leaves, or other
obstructions.
If you must drive with the tailgate open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at “Fresh”, the air flow control at “Floor” or “Face”, and
the fan control set to high.
