Disc brakes wear indicator
Your vehicle has disc brakes.
When your brake pads are worn and new
pads are required, you will hear a high-
pitched warning sound from your front
brakes or rear brakes. You may hear this
sound come and go or it may occur
whenever you depress the brake pedal.
Please remember that some driving con-
ditions or climates may cause a brake
squeal when you first apply (or lightly
apply) the brakes. This is normal and
does not indicate a problem with your
brakes.
Parking brake
Applying the parking brake
Foot type
To engage the parking brake, first apply
the foot brake and then depress the park-
ing brake pedal down as far as possible.Hand type
To engage the parking brake, first apply
the foot brake and then pull up the park-
ing brake lever as far as possible. In addition it is recommended that when
parking the vehicle on a incline, the shift
lever should be in a low gear on manual
transaxle vehicles or in the P (Park) posi-
tion on automatic transaxle vehicles.
WARNING
- Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking
performance, which could lead to aserious accident.
CAUTION
To avoid costly brake repairs, do not continue to drive with wornbrake pads.
Always replace brake pads as complete front or rear axle sets.

Driving your vehicle
Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
kilometers (miles) you can get from a litre
(gallon) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-ate rate. Don't make "kangaroo" starts or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-tion. Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
Take care of your tyres. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tyre
wear. Check the tyre pressures at leastonce a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting kerbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tyre wear and may
also result in other problems as well as
greater fuel consumption. Keep your car in good condition. For
better fuel economy and reduced
maintenance costs, maintain your carin accordance with the maintenance
schedule in section 7. If you drive your
car in severe conditions, more frequentmaintenance is required (see section 7
for details).
Keep your car clean. For maximum service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel con-
sumption and also contribute to corro-sion.
Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel
economy.
Don't let the engine idle longer than necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.
ECONOMICAL OPERATION

Driving your vehicle
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, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with themaintenance schedule in section 7.
Before winter, have your coolant tested toassure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorised HYUNDAI
dealer or a service station.Change to "winter weight" oil if
necessary In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorised HYUNDAI dealer.
Check spark plugs and ignition system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING
- Tyre chains
The use of chains may adversely affect vehicle handling.
Do not exceed 30 km/h (20 mph) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked- wheel braking.
CAUTION
Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

When you are ready to leave after park-
ing on a hill
1. With the manual transaxle in Neutral
or automatic transaxle in P (Park),
apply your brakes and hold the brake
pedal down whilst you:

and

2. Slowly remove your foot from the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks. Maintenance when trailer towing
Your vehicle will need service more often
when you regularly pull a trailer.
Important items to pay particular atten-tion to include engine oil, automatic
transaxle fluid, axle lubricant and cooling
system fluid. Brake condition is another
important item to frequently check. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re trailering, it’s a good idea to review
these sections before you start your trip.
Don’t forget to also maintain your trailer
and towbar. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all towbar nutsand bolts should be tight.
CAUTION
Due to higher load during trailer
usage, overheating might occurin hot days or during uphill driv- ing. If the coolant gauge indicatesover-heating, switch off the A/C
and stop the vehicle in a safe area to cool down the engine.
When towing check transaxle fluid more frequently.
WARNING - Parking brake
It can be dangerous to get out of
your vehicle if the parking brake is
not firmly set.
If you have left the engine running,
the vehicle can move suddenly. You
or others could be seriously or
fatally injured.

What to do in an emergency
EMERGENCY STARTING
Connect cables in numerical order and
disconnect in reverse order.
Refer to the following page for written
procedure. Jump starting
Jump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting proce-
dures. If in doubt, we strongly recom-
mend that you have a competent techni-
cian or towing service jump start your
vehicle.
CAUTION
Use only a 12-volt jumper system.
You can damage a 12-volt startingmotor, ignition system, and other
electrical parts beyond repair byuse of a 24-volt power supply (eithertwo 12-volt batteries in series or a24-volt motor generator set).
WARNING - Battery
• Keep all flames or sparks away from the battery. The battery pro-
duces hydrogen gas which may
explode if exposed to flame orsparks.
If these instructions are not fol-
lowed exactly, serious personal
injury and damage to the vehicle
may occur! If you are not sure
how to follow this procedure,
seek qualified assistance.
Automobile batteries contain sul-
furic acid. This is poisonous and
highly corrosive. When jump
starting, wear protective glasses
and be careful not to get acid on
yourself, your clothing or on the
car.
Do not attempt to jump start the vehicle if the discharged battery
is frozen or if the electrolyte level
is low; the battery may rupture or
explode.
WARNING - Battery
Never attempt to check the elec-
trolyte level of the battery as this
may cause the battery to rupture or
explode causing serious injury.

Be sure to use the correct
front and rear jacking posi-
tions on the vehicle; never
use the bumpers or any other
part of the vehicle for jack
support.
The vehicle can easily roll off the jack causing serious
injury or death. No person
should place any portion of
their body under a vehicle that
is supported only by a jack;
use vehicle support stands.
Do not start or run the engine whilst the vehicle is on the
jack.
Do not allow anyone to remain in the vehicle whilst it is on
the jack.
Make sure any children pres- ent are in a secure place away
from the road and from the
vehicle to be raised with the
jack.
IF YOU HAVE A FLAT TYRE
Jack and tools
The jack, jack handle, and wheel
brace are stored in the luggage com-
partment. Pull up the luggage box
cover to reach this equipment.

Jacking instructions
The jack is provided for emergency
tyre changing only.
To prevent the jack from “rattling”
whilst the vehicle is in motion, store it
properly.
Follow jacking instructions to reduce
the possibility of personal injury.
WARNING - Changing
tyres
Never attempt vehicle repairs in the traffic lanes of a public
road or highway.
Always move the vehicle com- pletely off the road and onto

What to do in an emergency
If you have a tyre gauge, remove the
valve cap and check the air pressure.
If the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the cor-
rect pressure. If it is too high, adjust
it until it is correct. 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, buyanother and install it as soon as pos-
sible.
After you have changed wheels,
always secure the flat tyre in its place
and return the jack and tools to their
proper storage locations.To prevent the jack, jack handle,
wheel brace and spare tyre from rat-
tling whilst the vehicle is in motion,
store them properly.CAUTION
Your vehicle has metric threads
on the wheel studs and nuts.Make certain during wheel removal that the same nuts thatwere removed are reinstalled -or, if replaced, that nuts withmetric threads and the same chamfer configuration are used.Installation of a non-metricthread nut on a metric stud or vice-versa will not secure thewheel to the hub properly andwill damage the stud so that it must be replaced.
Note that most nuts do not havemetric threads. Be sure to useextreme care in checking forthread style before installing aftermarket nuts or wheels. If indoubt, consult an authorisedHYUNDAI dealer.
WARNING - Wheel studs
If the studs are damaged, they
may lose their ability to retain
the wheel. This could lead to theloss of the wheel and a collisionresulting in serious injuries.
WARNING - Inadequate
spare tyre pressure
Check the inflation pressures as
soon as possible after installing
the spare tyre. Adjust it to the
specified pressure, if necessary.
Refer to “Tyres and wheels” sec-tion 8.

TOWING
Towing service
If emergency towing is necessary, we
recommend having it done by an autho-
rised HYUNDAI dealer or a commercial
tow-truck service. Proper lifting and tow-
ing procedures are necessary to prevent
damage to the vehicle. The use of wheeldollies or flatbed is recommended.
For trailer towing guidelines information, refer to “Trailer towing” in section 5.
It is acceptable to tow the vehicle with the
rear wheels on the ground (without dol-
lies) and the front wheels off the ground.
If any of the loaded wheels or suspen- sion components are damaged or the
vehicle is being towed with the front
wheels on the ground, use a towing dolly
under the front wheels.
When being towed by a commercial tow
truck and wheel dollies are not used, the
front of the vehicle should always be lift-
ed, not the rear.

If towing is necessary, we recommend
you to have it done by an authorised
HYUNDAI dealer or a commercial tow
truck service.
If towing service is not available in an
emergency, your vehicle may be tem-
porarily towed using a cable or chain
secured to the emergency towing hook
under the front/rear of the vehicle. Use
extreme caution when towing the vehicle.
A driver must be in the vehicle to steer it
and operate the brakes.
Towing in this manner may be done only
on hard-surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, power train, steering and
brakes must all be in good condition.
Do not use the tow hooks to pull a vehi-
cle out of mud, sand or other condi-
tions from which the vehicle cannot be
driven out under its own power.
Avoid towing a vehicle heavier than the vehicle doing the towing.
The drivers of both vehicles should communicate with each other frequent-
ly. Before emergency towing, check that
the hook is not broken or damaged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply steady and even force.
To avoid damaging the hook, do not pull from the side or at a vertical angle.
Always pull straight ahead.
WARNING
Use extreme caution when towing
the vehicle.
driving manoeuvres which would
place excessive stress on the
emergency towing hook and tow-
ing cable or chain. The hook and
towing cable or chain may break
and cause serious injury or dam-
age.
If the disabled vehicle is unable to be moved, do not forcibly con-
tinue the towing. Contact an
authorised HYUNDAI dealer or a
commercial tow truck service for
assistance.
Tow the vehicle as straight ahead as possible.
Keep away from the vehicle dur- ing towing.CAUTION
Attach a towing strap to the tow
hook.
Using a portion of the vehicle other than the tow hooks for tow-ing may damage the body of yourvehicle.
