Engine Coolant Temperature Gauge
„3.5-Inch
OBC3040007/OBC3040008
„10.25-Inch
This gauge indicates the temperature
of the engine coolant when the ignition
switch is in the ON position.
NOTICE
If the gauge pointer moves beyond the
normal range area toward the “130”
position, it indicates overheating that
may damage the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to “If the Engine
Overheats” in chapter 8.
WARNING
Never remove the radiator cap or
reservoir cap when the engine is hot.
The engine coolant is under pressure
and could cause severe burns. Wait
until the engine is cool before adding
coolant to the reservoir.
Fuel Gauge

on a slippery surface. Be especially
careful when braking, accelerating or
shifting gears. On a slippery surface,
an abrupt change in vehicle speed can
cause the drive wheels to lose traction
and may cause loss of vehicle control
resulting in an accident.
WARNING
Do not use the engine brake (shifting
from a higher gear to lower gear)
rapidly on slippery roads. The vehicle
may slip causing an accident.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:

[ALWAYS wear your seatbelt. In a
collision, an unbelted occupant
is significantly more likely to be
seriously injured or killed than a
properly belted occupant.

[Avoid high speeds when cornering or
turning.

[Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.

[The risk of rollover is greatly
increased if you lose control of your
vehicle at highway speeds.

[Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.

[In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.

[HYUNDAI recommends you follow all
posted speed limits.

Good driving practices

[Never take the vehicle out of gear and
coast down a hill. This is extremely
hazardous. Always leave the vehicle
in gear.

[Don’t “ride” the brakes. This can cause
them to overheat and malfunction.
Instead, when you are driving down a
long hill, shift to a lower gear. When
you do this, the engine braking will
help slow down the vehicle.

[Slow down before shifting to a lower
gear. This will help avoid over-revving
the engine, which can cause damage.

[Slow down when you encounter cross
winds. This gives you much better
control of your vehicle.

[Be sure the vehicle is completely
stopped before you attempt to shift
into reverse. The transmission can be
damaged if you do not.

[Exercise extreme caution when driving
on a slippery surface. Be especially
careful when braking, accelerating or
shifting gears. On a slippery surface,
an abrupt change in vehicle speed can
cause the drive wheels to lose traction
and the vehicle to go out of control. WARNING

[Always buckle-up! In a collision, an
unbelted occupant is significantly
more likely to be seriously injured
or killed than a properly belted
occupant.

[Avoid high speeds when cornering or
turning.

[Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.

[The risk of rollover is greatly
ncreased if you lose control of your
vehicle at highway speeds.

[Loss of control often occurs if two or
more wheels drop off the roadway
and the driver oversteers to reenter
the roadway.

[In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.

[Never exceed posted speed limits.

Driving your vehicle
Ignition key interlock system
(if equipped)
The ignition key cannot be removed
unless the shift lever is in the P (Park)
position.
3DUNLQJ
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake, and
place the ignition switch in the LOCK/
OFF position. Take the Key with you
when exiting the vehicle.
WARNING
When you stay in the vehicle with
the engine running, be careful not to
depress the accelerator pedal for a long
period of time. The engine or exhaust
system may overheat and start a fire.
The exhaust gas and the exhaust
system are very hot. Keep away from
the exhaust system components.
Do not stop or park over flammable
materials, such as dry grass, paper or
leaves. They may ignite and cause a
fire.
Good driving practices

[Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.

[Never move the shift lever into P
(Park) when the vehicle is in motion.

[ Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).

[Do not move the shift lever to N
(Neutral) when driving. Doing so may
result in an accident because of a loss
of engine braking and the transmission
could be damaged.

[Driving uphill or downhill, always shift
to D (Drive) when driving forward or to
R (Reverse) when driving backwards,
and check the gear position indicated
on the cluster before driving. If you
drive in the opposite direction of the
selected gear, the engine will turn
off and a serious accident might be
occurred due to the degraded brake
performance.

[Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can result
in the brakes overheating, brake wear
and possibly even brake failure.

[When driving in manual shift mode,
slow down before shifting to a lower
gear. Otherwise, the lower gear may
not be engaged if the engine rpms are
outside of the allowable range.

[Always apply the parking brake when
leaving the vehicle. Do not depend on
placing the transmission in P (Park) to
keep the vehicle from moving.

[Exercise extreme caution when driving
on a slippery surface. Be especially
careful when braking, accelerating or
shifting gears. On a slippery surface,
an abrupt change in vehicle speed can
cause the drive wheels to lose traction
and may cause loss of vehicle control
resulting in an accident.

[Under certain conditions, such as
repeated stop-and-go launches on
steep grades, sudden take off or
acceleration, or other harsh driving
conditions, the transmission clutch
temperatures will increase excessively.
Finally the clutch in transmission could
be overheated.

[When the clutch is overheated, the
safe protection mode engages and the
gear position

[indicator on the cluster blinks with
a chime. At this time, ‘Transmission
temp is high! Stop safely’ warning
message will appear on the LCD
display and driving may not be
smooth.

[If this occurs, pull over to a safe
location, stop the vehicle with the
engine running, apply the brakes and
shift the vehicle to P (Park), and allow
the transmission to cool.

[If you ignore this warning, the driving
condition may become worse. You
may experience abrupt shifts, frequent
shifts, or jerkiness. To return to the
normal driving condition, stop the
vehicle and apply the foot brake or
shift into P (Park). Then allow the
transmission to cool for a few minutes
with engine on, before driving off.

[When possible, drive the vehicle
smoothly.

[If the vehicle continues to be driven
and the clutch temperatures reach
the maximum temperature limit,
the ‘Trans Hot! Park with engine on’
warning will be displayed. When this
occurs the clutch is disabled until the
clutch cools to normal temperatures.

[The warning will display a time to wait
for the transmission to cool.

[If this occurs, pull over to a safe
location, stop the vehicle with the
engine running, apply the brakes and
shift the vehicle to P (Park), and allow
the transmission to cool.

[When the message ‘Trans cooled.
Resume driving’, appears you can
continue to drive your vehicle.

[When possible, drive the vehicle
smoothly.
If any of the warning messages in the
LCD display continue to blink, for your
safety, we recommend that you contact
a HYUNDAI authorised repairer and have
the system checked.
