Driving your vehicle
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet.
The risk of hydroplaning increases as
the depth of tyre tread decreases, refer
to “Tyre replacement” in chapter 9.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them several
times whilst the vehicle is moving
slowly.
Highway driving
Tyres
Adjust the tyre inflation, as specified.
Under-inflation may overheat or damage
the tyres.
Do not install worn-out or damaged
tyres, which may reduce traction or fail
the braking operation.

Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine
coolant level and the engine oil before
driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

Two labels on your driver’s door sill show
how much weight your vehicle was
designed to carry: the Tyre and Loading
Information Label and the Certification
Label.
Before loading your vehicle, familiarize
yourself with the following terms for
determining your vehicle’s weight
ratings, from the vehicle’s specifications
and the Certification Label:
Base Kerb Weight
This is the weight of the vehicle
including a full tank of fuel and all
standard equipment. It does not
include passengers, cargo, or optional
equipment.
Vehicle Kerb Weight
This is the weight of your new vehicle
when you picked it up from your dealer
plus any aftermarket equipment.
Cargo Weight
This figure includes all weight added to
the Base Kerb Weight, including cargo
and optional equipment.
GAW (Gross Axle Weight)
This is the total weight placed on each
axle (front and rear) - including vehicle
kerb weight and all payload.
GAWR (Gross Axle Weight Rating)
This is the maximum allowable weight
that can be carried by a single axle (front
or rear). These numbers are shown on
the Certification Label. The total load on
each axle must never exceed its GAWR.GVW (Gross Vehicle Weight)
This is the Base Kerb Weight plus actual
Cargo Weight plus passengers.
GVWR (Gross Vehicle Weight Rating)
This is the maximum allowable weight
of the fully loaded vehicle (including
all options, equipment, passengers
and cargo). The GVWR is shown on
the Certification Label located on the
driver’s door sill.
Overloading
WARNING
The Gross Axle Weight Rating (GAWR)
and the Gross Vehicle Weight Rating
(GVWR) for your vehicle are on the
Certification Label attached to the
driver’s (or front passenger’s) door.
Exceeding these ratings can cause an
accident or vehicle damage. You can
calculate the weight of your load by
weighing the items (and people) before
putting them in the vehicle. Be careful
not to overload your vehicle.

If the engine doesn’t turn over
or turns over slowly
[ Be sure the shift lever is in N (Neutral)
or P (Park) if it is an automatic
transmission/dual clutch transmission
vehicle. The engine starts only when
the shift lever is in N (Neutral) or P
(Park).
[ Check the battery connections to be
sure they are clean and tight.
[ Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to start
it. This could cause damage to your
vehicle. See instructions for “Jump
Starting” provided in this chapter.
CAUTION
Push or pull starting the vehicle may
cause the catalytic converter to
overload which can lead to damage to
the emission control system.
If the engine turns over normally
but doesn’t start
[ Check the fuel level and add fuel if
necessary.
If the engine still does not start, we
recommend that you call a HYUNDAI
authorised repairer for assistance.

Emergency situations
Tyre pressure monitoring
system
WARNING
Over-inflation or under-inflation can
reduce tyre life, adversely affect
vehicle handling, and lead to sudden
tyre failure that may cause loss of
vehicle control resulting in an accident.
Each tyre, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tyre inflation pressure label. (If your
vehicle has tyres of a different size
than the size indicated on the vehicle
placard or tyre inflation pressure label,
you should determine the proper tyre
inflation pressure for those tyres.)
As an added safety feature, your
vehicle has been equipped with a tyre
pressure monitoring system (TPMS)
that illuminates a low tyre pressure
telltale when one or more of your
tyres is significantly under-inflated.
Accordingly, when the low tyre pressure
telltale illuminates, you should stop and
check your tyres as soon as possible,
and inflate them to the proper pressure.
Driving on a significantly under-inflated
tyre causes the tyre to overheat and can
lead to tyre failure.
Under-inflation also reduces fuel
efficiency and tyre tread life, and
may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tyre maintenance,
and it is the driver’s responsibility to
maintain correct tyre pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tyre pressure telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator
to indicate when the system is
not operating properly. The TPMS
malfunction indicator is combined with
the low tyre pressure telltale. When
the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tyre pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tyres or wheels on the vehicle that
prevent the TPMS from functioning
properly.
Always check the TPMS malfunction
telltale after replacing one or more tyres
or wheels on your vehicle to ensure that
the replacement or alternate tyres and
wheels allow the TPMS to continue to
function properly.
NOTICE
If any of the below happens, we
recommend that you have the system
checked by a HYUNDAI authorised
repairer.
1. The Low Tyre Pressure Telltale/
TPMS Malfunction Indicator does not
illuminate for 3 seconds when the
Engine Start/Stop button is pressed
to the ON position or when the
engine is running.
2. The TPMS Malfunction Indicator
remains illuminated after blinking for
approximately 1 minute.
3. The Low Tyre Pressure Position
Telltale remains illuminated.

Maintenance
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the vehicle
is being driven in severe conditions,
more frequent oil and filter changes are
required.
Drive belts
Inspect all drive belts for evidence
of cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked
periodically for proper tension and
adjusted as necessary.
CAUTION
When you are inspecting the belt, place
the ignition switch to the lock/off or
ACC position.
Fuel filter (Except Europe)
A clogged filter can limit the speed
at which the vehicle may be driven,
damage the emission system and cause
multiple issues such as hard starting.
If an excessive amount of foreign
matter accumulates in the fuel tank, the
filter may require replacement more
frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
We recommend that the fuel filter be
replaced by a HYUNDAI authorised
repairer.
Fuel filter (For Europe)
This petrol powered vehicle is equipped
with a lifetime fuel filter that is
integrated with the fuel tank. Regular
maintenance or replacement is not
needed; however, the quality of fuel
used may impact the frequency of
maintenance needed. If there are any
fuel related problems like fuel flow
restriction, surging, loss of power,
hard starting problem etc, fuel filter
inspection or replacement may be
needed. We recommend the fuel filter
be inspected or replaced by a HYUNDAI
authorised repairer.
Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
We recommend that the fuel lines, fuel
hoses and connections be replaced by a
HYUNDAI authorised repairer.
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or
fuel filler cap is correctly replaced.

Maintenance
Recommended cold tyre
inflation pressures
All tyre pressures (including the spare)
should be checked when the tyres are
cold. “Cold tyres” means the vehicle has
not been driven for at least three hours
or driven less than one mile (1.6 km).
Warm tyres normally exceed
recommended cold tyre pressures by 28
to 41 kPa (4 to 6 psi). Do not release air
from warm tyres to adjust the pressure
or the tyres will be under-inflated. For
recommended inflation pressure, refer
to “Tyre and Wheels” in chapter 2.
WARNING
Recommended pressures must be
maintained for the best ride, vehicle
handling, and minimum tyre wear.
Over-inflation or under-inflation can
reduce tyre life, adversely affect
vehicle handling, and lead to sudden
tyre failure that could result in loss of
vehicle control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and other
tyre failures that can result in the
loss of vehicle control resulting in an
accident. This risk is much higher on
hot days and when driving for long
periods at high speeds.
NOTICE
[ 8 Q G H U L Q I O D W L R Q D O V R U H V X O W V L Q
excessive wear, poor handling
and reduced fuel economy. Wheel
deformation also is possible. Keep
your tyre pressures at the proper
levels. If a tyre frequently needs
refilling, we recommend that the
system be checked by a HYUNDAI
authorised repairer.
[ 2 Y H U L Q I O D W L R Q S U R G X F H V D K D U V K U L G H
excessive wear at the centre of the
tyre tread, and a greater possibility of
damage from road hazards.
Check tyre inflation pressure
Check your tyres including the spare tyre
once a month or more.
How to check
Use a good quality tyre pressure gauge
to check tyre pressure. You cannot tell if
your tyres are properly inflated simply by
looking at them. Radial tyres may look
properly inflated even when they are
under-inflated.
Remove the valve cap from the tyre
valve stem. Press the tyre gauge
firmly onto the valve to get a pressure
measurement. If the cold tyre inflation
pressure matches the recommended
pressure on the tyre and loading
information label, no further adjustment
is necessary. If the pressure is low, add
air until you reach the recommended
pressure. Make sure to put the valve
caps back on the valve stems. Without
the valve cap, dirt or moisture could
get into the valve core and cause air
leakage. If a valve cap is missing, install
a new one as soon as possible.
