Check Smart Cruise Control System
The message will appear when the
vehicle to vehicle distance control
system is not functioning normally.
We recommend that you take your
vehicle to an authorized HYUNDAI
dealer and have the system checked.
To adjust the sensitivity of
Smart Cruise Control
The sensitivity of vehicle speed
when following the front vehicle to
maintain the set distance can be
adjusted. Go to the 'User Settings →
Driving Assist →Smart Cruise
Control Speed →Slow/Normal/Fast'
on the LCD display. You may select
one of the three stages you prefer.
- Slow:
Vehicle speed following the frontvehicle to maintain the set distance
is slower than normal speed.
- Normal: Vehicle speed following the frontvehicle to maintain the set distance
is normal.
- Fast: Vehicle speed following the frontvehicle to maintain the set distance
is faster than normal speed.
Information
The last selected speed sensitivity of
the smart cruise control is remained in
the system.
To convert to Cruise Control
mode
The driver may choose to only use
the Cruise Control mode (speed con-
trol function) by doing as follows:
1. Turn the Smart Cruise Control System on (the cruise indicator
light will be on but the system will
not be activated).

If you believe your brakes may bewet, apply them lightly while 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 tire tread
decreases, refer to "Tire 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 while the vehicle is moving
slowly.
Highway driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engineoil
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.

The severe weather conditions of
winter quickly wear out tires and
cause other problems. To minimize
winter driving problems, you should
take the following suggestions:
Information
Information for Snow Tires and Tire
Chains in the national language
(Bulgarian, Hungarian, Icelandic,
Polish) is provided in the Appendix.
Snow or icy conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause skids to occur.
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tires
If you mount snow tires on your vehi-
cle, make sure to use radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
The traction provided by snow tires
on dry roads may not be as high as
your vehicle's original equipment
tires. Check with the tire dealer for
maximum speed recommendations.
Information
Do not install studded tires without first
checking local and municipal regula-
tions for possible restrictions against
their use.

Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your vehi-
cle may be adversely affected.

Check battery and cables
The winter temperature increases
the battery consumption. Inspect
the battery and cables, as speci-
fied in the chapter 7. The battery
charging level can be checked by an
authorized HYUNDAI dealer or in a
service station.
Change to "winter weight" oil if
necessary
In some regions during winter, it is
recommended to use the "winter
weight" oil with lower viscosity. For
further information, refer to the chap-
ter 8. When you are not sure about a
type of winter weight oil, consult an
authorized HYUNDAI dealer. Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in the chapter 7.
If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
frozen, spray approved de-icing fluid
or glycerin into key holes. When a
lock opening is already covered with
ice, spray approved de-icing fluid
over the ice to remove it. When an
internal part of a lock freezes, try to
thaw it with a heated key. Carefully
use the heated key to avoid an injury. Use approved window washer
anti-freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorized
HYUNDAI dealer, and so are the
most vehicle accessory outlets. Do
not use engine coolant or other types
of anti-freeze solution to prevent any
damage to the vehicle paint.

Do not let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to hap-
pen when there is an accumulation
of snow or ice around or near the
rear brakes or if the brakes are wet.
When there is the risk that your park-
ing brake may freeze, temporarily
apply it with the shift lever in P
(Park). Also, block the rear wheels in
advance, so the vehicle may not roll.
Then, release the parking brake.Do not let ice and snow accumu-
late underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in such conditions during the
severe winter, you should check
underneath the vehicle on a regular
basis, so that moving the front
wheels and the steering components
is unblocked.
Carry emergency equipment
In accordance with weather condi-
tions, you should carry appropriate
emergency equipment, while driving.
Some of the items you may want to
carry include tire chains, tow straps
or chains, flashlight, emergency
flares, sand, shovel, jumper cables,
window scraper, gloves, ground
cloth, coveralls, blanket, etc.Do not place objects or materials
in the engine compartment
Putting objects or materials in the
engine compartment may cause an
engine failure or combustion,
because those may block the engine
cooling. Such damage will not be
covered by the manufacturer’s war-
ranty.

Trailer weight
What is the maximum safe weight of a
trailer? It should never weigh more
than the maximum trailer weight with
trailer brakes. But even that can be
too heavy. It depends on how you plan
to use your trailer. For example,
speed, altitude, road grades, outside
temperature and how often your vehi-
cle is used to pull a trailer are all
important. The ideal trailer weight can
also depend on any special equip-
ment that you have on your vehicle.
Tongue load
The tongue load is an important
weight to measure because it affects
the total Gross Vehicle Weight
(GVW) of your vehicle. The trailer
tongue should weigh a maximum of
10% of the total loaded trailer weight,
within the limits of the maximum trail-
er tongue load permissible.
After you've loaded your trailer,
weigh the trailer and then the tongue,
separately, to see if the weights are
proper. If they aren’t, you may be
able to correct them simply by mov-
ing some items around in the trailer.
Information
With increasing altitude the engine
performance decreases. From 1,000 m
above sea level and for every 1,000 m
thereafter 10% of vehicle/trailer
weight (trailer weighter + gross vehi-
cle weight) must be deducted.
i
Take the following precautions:
•Never load a trailer with more
weight in the rear than in the
front. The front should be
loaded with approximately
60% of the total trailer load;
the rear should be loaded with
approximately 40% of the total
trailer load.
Never exceed the maximum
weight limits of the trailer or
trailer towing equipment.
Improper loading can result in
damage to your vehicle and/or
personal injury. Check weights
and loading at a commercial
scale or highway patrol office
equipped with scales.

Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transmission fluid, axle lubri-
cant and cooling system fluid. Brake
condition is another important item to
frequently check. If you’re trailering,
it’s a good idea to review these items
before you start your trip. Don’t forget
to also maintain your trailer and
hitch. Follow the maintenance sched-
ule that accompanied your trailer and
check it periodically. Preferably, con-
duct the check at the start of each
day’s driving. Most importantly, all
hitch nuts and bolts should be tight.To prevent vehicle damage:
Due to higher load during trailer
usage, overheating might occur
on hot days or during uphill driv-
ing. If the coolant gauge indi-
cates over-heating, switch off
the air conditioner and stop the
vehicle in a safe area to cool
down the engine.
Do not switch off the engine while the coolant gauge indi-
cates over-heating.
(Keep the engine idle to cool
down the engine)
When towing check automatic transmission fluid more fre-
quently.
If your vehicle is not equipped with an air conditioner, you
should install a condenser fan
to improve engine performance
when towing a trailer.
