The coasting guide function informs
the driver when to take the foot off
from the accelerator by anticipating a
decelerating event* based on the
analysis of driving routes and road
conditions of the navigation. It
encourages the driver to remove foot
from the pedal and allow coasting
down the road with EV motor only.
This helps prevent unnecessary fuel
consumption and increases fuel effi-
ciency.
Information
Example of a deceleration event is
making a right/left turn, driving
through a rotary, entering or exiting a
highway (freeway), etc. Setting Coasting Guide function
Coasting Guide can be selected from
the User Settings mode in the cluster
LCD display by following the proce-
dure below.
1. Set the ignition switch in the ON
position.
2. Select 'User settings →
Convenience →Coasting guid-
ance' in the cluster LCD display.
Operation conditions
After selecting the function from the
User Settings mode, the system
enters the ready status by following
the procedure below.
1. Enter your destination information
in the navigation system
and select the driving route.
2. Check that the vehicle is in ECO
mode by driving the vehicle in D
(Drive).
3. Drive the vehicle between 40 km/h
~ 160 km/h.
Information
The operating speed may vary due to
difference between instrument cluster
and navigation effected by tyre infla-
tion level.
Information
Coasting guide is only a supplemental
function to assist with fuel-efficient
driving. Thus, the operating condi-
tions may be different in accordance
with traffic/road conditions (i.e. driv-
ing in a traffic jam, driving on a slope,
driving on a curve). Take the actual
driving conditions into consideration,
such as distances from the vehicles
ahead/behind, whilst referring to the
coasting guide function as guidance.

Driving your vehicle
If you believe your brakes may be
wet, apply them lightly whilst driv-
ing until normal braking operation
returns.
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 increas-
es as the depth of tyre tread
decreases, refer to "Tyre Tread" in
chapter 7.
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 sev-
eral times whilst the vehicle is mov-
ing 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.
Information
Never over-inflate your tyres above
the maximum inflation pressure, as
specified on your tyres.
Fuel, engine coolant and engine
oil
Driving at higher speeds on the high-
way 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.

Driving your vehicle
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, familiar-
ize yourself with the following terms
for determining your vehicle's weight
ratings, from the vehicle's specifica-
tions 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 option-
al equipment.
Vehicle Kerb Weight
This is the weight of your new vehicle
when you picked it up from your deal-
er 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 passen-
gers.
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.

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.

What to do in an emergency
Hybrid vehicle
Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in P (Park).
This vehicle does not have a regu-
lar 12V battery that needs periodic
replacement. It is lithium ion poly-
mer type integrated into the HEV
high voltage battery. The vehicle
has a 12V battery protection sys-
tem that cuts 12V battery from
vehicle draw to prevent full dis-
charge. If vehicle will not start, first
try pressing the 12V Battery Reset
switch (left side of the steering
wheel near the fuel door open
switch) to reconnect the 12V bat-
tery, but you must start vehicle
within 15 seconds of pressing the
12V Battery Reset switch. After
starting vehicle, operate the vehi-
cle safely outdoors in ready mode
stopped and/or drive it for 30 min-
utes total to charge the 12V battery
fully. Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, we
recommend that you call an autho-
rised HYUNDAI dealer for assis-
tance.
Plug-in hybrid vehicle
Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in 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.
Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, we
recommend that you call an autho-
rised HYUNDAI dealer for assis-
tance.Push or pull starting the vehicle
may cause the catalytic convert-
er to overload which can lead to
damage to the emission control
system.
CAUTION
Push or pull starting the vehicle
may cause the catalytic con-
verter to overload which can
lead to damage to the emission
control system.

What to do in an emergency
Tyre pressure monitoring sys-
tem
Each tyre, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard 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 pres-
sure 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 sig-
nificantly under-inflated tyre causes
the tyre to overheat and can lead to
tyre failure.
Under-inflation also reduces fuel effi-
ciency 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 mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tyre pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion 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 mal-
function indicator is combined with
the low tyre pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists.
When the malfunction indicator is illu-
minated, the system may not be able
to detect or signal low tyre pressure
as intended. TPMS malfunctions may
occur for a variety of reasons, includ-
ing the installation of replacement or
alternate tyres or wheels on the vehi-
cle that prevent the TPMS from func-
tioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tyres or wheels on your vehicle to
ensure that the replacement or alter-
nate tyres and wheels allow the
TPMS to continue to function proper-
ly.

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 con-
trol resulting in an accident.

wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly
turns slightly or “pulls” to one side
when travelling on smooth, level
road.
When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
Check the dual clutch transmission
P (Park) function.
Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
