Driving your vehicle
Starting and stopping the engine for
turbocharger intercooler
1. Do not race or accelerate the engine
immediately after starting the engine.
If the engine is cold, idle for several
seconds before sufficient lubrication is
ensured in the turbo charger unit.
2. After high speed or extended driving
that requires heavy engine load, idle
the engine about one minute before
turning the engine off. This idle time
will allow the turbocharger to cool
prior to shutting the engine off.
NOTICE
Do not turn off the engine immediately
after it has been subjected to a heavy
load. Doing so may cause severe
damage to the engine or turbo charger
unit.

Parking
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.
• Depressing both accelerator and brake
pedals at the same time can trigger
logic for engine power reduction to
assure vehicle deceleration. Vehicle
acceleration will resume after the
brake pedal is released.
• 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.

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 8. 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 puts additional burdens on the
battery system. Visually inspect the
battery and cables as described in
chapter 8. The level of charge in your
battery can be checked by an authorized
HYUNDAI dealer or a service station.
Change to “winter weight” oil if
necessary
In some climates it is recommended that
a lower viscosity “winter weight” oil be
used during cold weather. See chapter
2 for recommendations. If you aren’t
sure what weight oil you should use, we
recommend that you consult with an
authorized HYUNDAI dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as described
in chapter 8 and replace them if
necessary. Also check all ignition wiring
and components to be sure they are not
cracked, worn or damaged in any way.
To keep locks from freezing
To keep the locks from freezing, squirt
an approved de-icer fluid or glycerine
into the key opening. If a lock is covered
with ice, squirt it with an approved
de-icing fluid to remove the ice. If the
lock is frozen internally, you may be able
to thaw it out by using a heated key.
Handle the heated key with care to avoid
injury.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of anti-freeze as these may damage the
paint finish.
