while the vehicle is in gear on the
dynamometer. The vehicle can jump
forward and cause serious injury or
death.
Reducing the risk of a rollover
Your multi-purpose passenger vehicle is
defined as a Sports Utility Vehicle (SUV).
SUV’s have higher ground clearance
and a narrower track to make them
capable of performing in a wide variety
of off-road applications. The specific
design characteristics give them a higher
center of gravity than ordinary vehicles
making them more likely to roll over if
you make abrupt turns. Utility vehicles
have a significantly higher rollover rate
than other types of vehicles. Due to this
risk, driver and passengers are strongly
recommended to buckle their seat belts.
In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt.
There are steps that a driver can make
to reduce the risk of a rollover. If at all
possible, avoid sharp turns or abrupt
maneuvers, do not load your roof rack
with heavy cargo, and never modify your
vehicle in any way.

adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
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 specified
on your tires.
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.

control:

[Take corners at slower speeds than
you would with a passenger vehicle.

[ Avoid sharp turns and abrupt
maneuvers.

[ Do not modify your vehicle in any
way that you would raise the center
of gravity.

[ Keep tires properly inflated.

[ Do not carry heavy cargo on the roof.
WARNING
In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt. Make sure
all passengers are wearing their seat
belts.

Driving your vehicle6-76
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:
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 the vehicle to skid.
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
WARNING
Snow tires should be equivalent in size and type to the vehicle’s standard tires.
Otherwise, the safety and handling of your vehicle may be adversely affected.
We recommend that you use snow tires when road temperature is below 45°F (7°C).
If you mount snow tires on your vehicle, make sure to use the same Inflation pressure
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.
WINTER DRIVING

Driving your vehicle6-78
Chain Installation
When installing tire chains, follow the
manuf
acturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 20 mph (30 km/h)) with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tire chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if
available). Always place the vehicle in P
(Park), apply the parking brake and turn
off the engine before installing snow
chains.
NOTICE
When using tire chains:

[ Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension,
body and wheels.

[ Use SAE “S” class or wire chains.

[ If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.

[ To prevent body damage, retighten
the chains after driving 0.3~0.6 miles
(0.5~1.0 km).

[ Do not use tire chains on vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.

[ Use wire chains less than 0.47 in.
(12mm) thick to prevent damage to
the chain’s connection.
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 9. 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 temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. 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 In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not sure
about a type of winter weight oil, consult
an authorized HYUNDAI dealer.

06
6-79
Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 8. 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 specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized HYUNDAI
dealer, and most vehicle accessory
outlets. Do not use engine coolant or
other types of anti-freeze solution, to
prevent any damage to the vehicle paint.
Drive your vehicle when water vapor
condenses and accumulates inside the
exhaust pipes
When the vehicle is stopped for a
long time in winter while the engine is
running, water vapor may condense and
accumulate inside the exhaust pipes.
Water in the exhaust pipes may cause
noise, etc., but it is drained driving at
medium to high speed. Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen 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
parking brake may freeze, temporarily
apply it with the gear 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 accumulate
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, to ensure
that the front wheels and the steering
components is unblocked.
Carry emergency equipment
In accordance with weather conditions,
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 they may
block the engine cooling. Such damage
will not be covered by the manufacturer’s
warranty.
