Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, followthese suggestions:
Drive cautiously and allow extra dis-
tance for braking.
Avoid sudden movements in braking or steering.
When braking with non-ABS brakes pump the brake pedal with a light up-
and-down motion until the vehicle isstopped. If stalled in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, tyre chains, or other non-slip material under the drive
wheels to provide traction when stalled
in ice, snow, or mud. Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between 1st (First)
and R (Reverse) in vehicles equipped
with a manual transaxle or R (Reverse)
and any forward gear in vehicles
equipped with an automatic transaxle.
Do not race the engine, and spin the
wheels as little as possible. If you are still
stuck after a few tries, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating and possible dam-
age to the transaxle.
SPECIAL DRIVING CONDITIONS
1JBB3302
WARNING -
ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
WARNING - Downshifting
Downshifting with an automatic
transaxle, whilst driving on slipperysurfaces can cause an accident.
The sudden change in tyre speed
could cause the tyres to skid. Be
careful when downshifting on slip-
pery surfaces.
CAUTION
Prolonged rocking may cause engine over-heating, transaxle dam-age or failure, and tyre damage.

Towbars
It's important to have the correct towbar
equipment. Crosswinds, large trucks
going by, and rough roads are a few rea-
sons why you’ll need the right towbar.
Here are some rules to follow:
Will you have to make any holes in thebody of your vehicle when you install a
trailer towbar? If you do, then be sure
to seal the holes later when you
remove the towbar.
If you don’t seal them, deadly carbon
monoxide (CO) from your exhaust can
get into your vehicle, as well as dirt and
water.
The bumpers on your vehicle are not intended for towbars. Do not attach
rental towbars or other bumper-type
towbars to them. Use only a frame-
mounted towbar that does not attach to
the bumper.
HYUNDAI trailer towbar accessory is available at an authorised HYUNDAI
dealer.
✽✽ NOTICE
We recommend only genuine
HYUNDAI towbars (the towbars are
made and tested in Australia/NZ for
local conditions).
Safety chains
You should always attach chains
between your vehicle and your trailer.
Cross the safety chains under the tongue
of the trailer so that the tongue will not
drop to the road if it becomes separated
from the towbar.
Instructions about safety chains may be
provided by the towbar manufacturer or
by the trailer manufacturer. Follow the
manufacturer’s recommendation for
attaching safety chains. Always leave just
enough slack so you can turn with your
trailer. And, never allow safety chains to
drag on the ground. Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to your
country’s regulations and that it is prop-
erly installed and operating correctly.
If your trailer weight exceeds the maxi-
mum allowed weight without trailer
brakes, then the trailer will also require its
own brakes as well. Be sure to read and
follow the instructions for the trailer
brakes so you’ll be able to install, adjust
and maintain them properly.
Don’t tap into or modify your vehicle's
brake system.
WARNING - Trailer brakes
Do not use a trailer with its own
brakes unless you are absolutely
certain that you have properly set
up the brake system. This is not a
task for amateurs. Use an experi-
enced, competent trailer shop for
this work.

Parking on hills
Generally, if you have a trailer attached to
your vehicle, you should not park your
vehicle on a hill. People can be seriously
or fatally injured, and both your vehicle
and the trailer can be damaged if unex-
pectedly roll down hill. However, if you ever have to park your
trailer on a hill, here's how to do it:
1. Pull the vehicle into the parking space.
Turn the steering wheel in the direction
of the kerb (left if headed down hill,
right if headed up hill).
2. If the vehicle has a manual transaxle, place the car in neutral. If the vehicle
has an automatic transaxle, place the
car in P (Park).
3. Set the parking brake and shut off the vehicle.
4. Place chocks under the trailer wheels on the down hill side of the wheels.
5. Start the vehicle, hold the brakes, shift to neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6. Reapply the brakes, reapply the park- ing brake and shift the vehicle to R
(Reverse) for manual transaxle or P
(Park) for automatic transaxle.
7. Shut off the vehicle and release the vehicle brakes but leave the parking
brake set.CAUTION
When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the enginecoolant temperature gauge toensure the engine does not over- heat.
If the needle of the coolant tem-perature gauge moves across thedial towards “H” (HOT), pull overand 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 loose.

6. Loosen the wheel nuts counter-
clockwise one turn each using the
sequence shown above, but do
not remove any nut until the tyre
has been raised off the ground. 7. Place the jack at the front or rear
jacking position closest to the tyre
you are changing. Place the jackat the designated locations under
the frame. The jacking positions
are plates welded to the frame
with two tabs and a raised dot to
index with the jack.
WARNING - Changing a tyre
To prevent vehicle movement
whilst changing a tyre, always
set the parking brake fully,
and always block the wheel
diagonally opposite the wheel
being changed.
We recommend that the wheels of the vehicle be
blocked, and that no person
remain in the vehicle that is
being jacked.

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.
OEN076053
Tread wear indicator(Continued)
The use of any other tyre size
or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tyre clearance, snow tyre
clearance, and speedometer
reliability.
It is best to replace all four tyres at the same time. If that
is not possible, or necessary,
then replace the two front or
two rear tyres as a pair.Replacing just one tyre can
seriously affect your vehicle’shandling.
The ABS works by comparing the speed of the wheels. Tyre
size can affect wheel speed.
When replacing tyres, all 4
tyres must use the same size
originally supplied with the
vehicle. Using tyres of a dif-
ferent size can cause the ABS
(Anti-lock Brake System) and
ESP (Electronic Stability
Program) or ESC (Electronic
Stability Control) (if equipped)
to work irregularly.WARNING - 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.
