carefully when carrying items on
the roof rack. Severe wind updrafts,
caused by passing vehicles or natural
causes, can cause sudden upward
pressure on items loaded on the
roof rack. This is especially true
when carrying large, flat items such
as wood panels or mattresses. This
could cause the items to fall off the
roof rack and cause damage to your
vehicle or others around you.

EXTERIOR FEATURES

Driving your vehicle
Before entering the vehicle

[Be sure all windows, outside mirror(s),
and outside lights are clean and
unobstructed.

[Remove frost, snow, or ice.

[Visually check the tyres for uneven
wear and damage.

[Check under the vehicle for any sign
of leaks.

[Be sure there are no obstacles behind
you if you intend to back up.
Before starting

[Make sure the bonnet, the tailgate,
and the doors are securely closed and
locked.

[Adjust the position of the seat and
steering wheel.

[Adjust the inside and outside rearview
mirrors.

[Verify all the lights work.

[Fasten your seat belt. Check that all
passengers have fastened their seat
belts.

[Check the gauges and indicators in the
instrument panel and the messages
on the instrument display when the
ignition switch is in the ON position.

[Check that any items you are carrying
are stored properly or fastened down
securely.
WARNING
To reduce the risk of SERIOUS
INJURY or DEATH, take the following
precautions:

[ALWAYS wear your seat belt. All
passengers must be properly belted
whenever the vehicle is moving. For
more details, refer to “Seat Belts” in
chapter 3.

[Always drive defensively. Assume
other drivers or pedestrians may be
careless and make mistakes.

[Stay focused on the task of driving.
Driver distraction can cause
accidents.

[Leave plenty of space between you
and the vehicle in front of you.
WARNING
NEVER drink or take drugs and drive.
Drinking or taking drugs and driving
is dangerous and may result in an
accident and SERIOUS INJURY or
DEATH.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Just
one drink can reduce your ability to
respond to changing conditions and
emergencies and your reaction time
gets worse with each additional drink.
Driving whilst under the influence
of drugs is as dangerous or more
dangerous than driving under the
influence of alcohol.
You are much more likely to have a
serious accident if you drink or take
drugs and drive. If you are drinking or
taking drugs, don’t drive. Do not ride
with a driver who has been drinking
or taking drugs. Choose a designated
driver or call a taxi.
BEFORE DRIVING

6-70
Driving your vehicle
Driving with a trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you must get to
know your trailer. Acquaint yourself with
the feel of handling and braking with the
added weight of the trailer. And always
keep in mind that the vehicle you are
driving is now longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer towbar
and platform, safety chains, electrical
connector(s), lights, tyres and brakes.
During your trip, occasionally check
to be sure that the load is secure, and
that the lights and trailer brakes are still
working.
Distance
Stay at least twice as far behind the
vehicle ahead as you would when driving
your vehicle without a trailer. This can
help you avoid situations that require
heavy braking and sudden turns.
Passing
You will need more passing distance up
ahead when you’re towing a trailer. And,
because of the increased vehicle length,
you’ll need to go much farther beyond
the passed vehicle before you can return
to your lane.
Backing up
Hold the bottom of the steering wheel
with one hand. Then, to move the trailer
to the left, move your hand to the left.
To move the trailer to the right, move
your hand to the right. Always back up
slowly and, if possible, have someone
guide you.
Making turns
When you’re turning with a trailer, make
wider turns than normal. Do this so your
trailer won’t strike soft shoulders, kerbs,
road signs, trees, or other objects. Avoid
jerky or sudden manoeuvres. Signal well
in advance.
Turn signals
When you tow a trailer, your vehicle has
to have a different turn signal flasher and
extra wiring. The green arrows on your
instrument panel will flash whenever you
signal a turn or lane change. Properly
connected, the trailer lights will also
flash to alert other drivers you’re about
to turn, change lanes, or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer
are burned out. Thus, you may think
drivers behind you are seeing your
signals when, in fact, they are not. It’s
important to check occasionally to be
sure the trailer bulbs are still working.
You must also check the lights every
time you disconnect and then reconnect
the wires.
WARNING
Do not connect a trailer lighting system
directly to your vehicle’s lighting
system. Use an approved trailer wiring
harness.
Failure to do so could result in damage
to the vehicle electrical system and/or
personal injury.
We recommend that you have the
system checked by a HYUNDAI
authorised repairer as soon as possible.

If you have a tyre gauge, check the tyre
pressure (see “Tyres and Wheels” in
chapter 2 for tyre pressure instructions.).
If the pressure is lower or higher than
recommended, drive slowly to the
nearest service station and adjust it to
the recommended pressure. Always
reinstall the valve cap after checking
or adjusting tyre pressure. If the cap
is not replaced, air may leak from the
tyre. If you lose a valve cap, buy another
and install it as soon as possible. After
changing tyres, secure the flat tyre and
return the jack and tools to their proper
storage locations.

tyre. Adjust it to the recommended
pressure.

after driving over 50 km if tyres are
replaced. Re-check the tyre wheel
lug nuts after driving over 1,000 km.
CAUTION
Your vehicle has metric threads on
the studs and lug nuts. Make certain
during tyre changing that the same
nuts that were removed are reinstalled.
If you have to replace your lug nuts
make sure they have metric threads to
avoid damaging the studs and ensure
the wheel is properly secured to the
hub. We recommend that you consult
a HYUNDAI authorised repairer for
assistance.
If any of the equipment such as the jack,
lug nuts, studs, or other equipment is
damaged or in poor condition, do not
attempt to change the tyre and call for
assistance.
Use of compact spare tyres
(if equipped)
Compact spare tyres are designed for
emergency use only. Drive carefully
on the compact spare tyre and always
follow the safety precautions.
