Driving on grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 70 km/h (45mph) to reduce the possibility of engine
and transaxle overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transaxle,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimise heat build up
and extend the life of your transaxle.E140407AUN-EA
Parking on hills
Generally, you should not park your vehi-
cle, with a trailer attached, on a hill.
People can be seriously injured or cause
fatality, and both your vehicle and the
trailer can be damaged if they begin a
downhill trajectory.
However, if you ever have to park your
trailer on a hill, here’s how to do it:
1. Apply your brakes, but don’t shift into
gear.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the brakes until the chocks absorb the load.
4. Reapply the brakes. Apply your park- ing brake, and then shift to R
(Reverse) for a manual transaxle or P
(Park) for an automatic transaxle.
5. Release the brakes.
CAUTION
When towing a trailer on steep grades (in excess of 6%) payclose attention to the enginecoolant temperature gauge to
ensure the engine does not over- heat.
If the needle of the coolant tem-perature gauge moves across thedial towards “H” (HOT), pull over
and stop as soon as it is safe to do so, and allow the engine to idleuntil it cools down. You may pro-
ceed once the engine has cooledsufficiently.
You must decide driving speed depending on trailer weight anduphill grade to reduce the possi-
bility of engine and transaxle overheating.
WARNING - Parking on a
hill
Parking your vehicle on a hill with a
trailer attached could cause seri-
ous injury or death, should the trail-
er break lose.

If you do decide to pull a trailer
Here are some important points if you
decide to pull a trailer:
Consider using a sway control. You canask a towbar dealer about sway con- trol.
Do not do any towing with your car dur- ing its first 2,000 km (1,200 miles) in
order to allow the engine to properly
break in. Failure to heed this caution
may result in serious engine or
transaxle damage.
When towing a trailer, be sure to con- sult an authorised HYUNDAI dealer for
further information on additional
requirements such as a towing kit, etc.
Always drive your vehicle at a moder- ate speed (less than 100 km/h (60mph)).
On a long uphill grade, do not exceed 70 km/h (45 mph) or the posted towing
speed limit, whichever is lower.

Weight of the trailer
How heavy can a trailer safely be? It
should never weigh more than the maxi-
mum 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 vehicle 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. E140602AEN-EA
Weight of the trailer tongue
The tongue load of any trailer is an
important weight to measure because it
affects the total gross vehicle weight
(GVW) of your vehicle. This weight
includes the kerb weight of the vehicle,
any cargo you may carry in it, and the
people who will be riding in the vehicle.
And if you will tow a trailer, you must addthe tongue load to the GVW because
your vehicle will also be carrying that
weight.
The trailer tongue should weigh within
the limits of the maximum trailer 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 moving some
items around in the trailer.
Tongue loads can be increased or
decreased by redistributing the load in
the trailer. This can be verified by check-
ing the total weight of the loaded trailer
and then checking the load on the
tongue.
WARNING -
Trailer
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 approximately40% of the total trailer load.

TYRES AND WHEELS
G200100AUN-EA
Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle. G200200AFD-EA 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 than1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tyre
wear.
For recommended inflation pressure
refer to “Tyre and wheels” in section9. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tyre underin-
flation
Severe underinflation (70 kPa (10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation andother tyre failures that can
result in the loss of vehicle con-
trol leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

G200500AUN-EA Wheel alignment and tyre balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tyre
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tyre
wear or your vehicle pulling one way
or the other, the alignment may needto be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.G200600BFD-EA
Tyre replacement
If the tyre is worn evenly, a tread
wear indicator will appear as a solid
band across the tread. This showsthere is less than 1.6 mm (1/16 inch)
of tread left on the tyre. Replace the
tyre when this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tyre.
CAUTION
Improper wheel weights can
damage your vehicle's alumini- um wheels. Use only approvedwheel weights.
1LDA5026
Tread wear indicatorWARNING - Replacing tyres
Driving on worn-out tyres is very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-tion.
Your vehicle is equipped with tyres designed to provide for
safe ride and handling capa-
bility. Do not use a size andtype of tyre and wheel that is
different from the one that is
originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to han-
dling failure or rollover and
serious injury. When replacing
the tyres, be sure to equip all
four tyres with the tyre and
wheel of the same size, type,
tread, brand and load-carrying
capacity.
