Maintenance when trailer towing
Your vehicle will need service more often
when you regularly towing 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 check frequently. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re towing, 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.
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 can be seriously injured
or cause fatality.CAUTION
Due to higher load during trailer usage, overheating might occurin hot days or during uphill driv- ing. If the coolant gauge indicates
over-heating, switch off the A/C and stop the vehicle in a safe areato cool down the engine.
When towing check transaxle fluid more frequently.
If your vehicle is not equipped with the air conditioner, youshould install a condenser fan to improve engine performance
when towing a trailer.

EMERGENCY STARTING
F040100AUN
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. F040101AFD-EA
Jump starting procedure
1. Make sure the booster battery is 12-
volt and that its negative terminal is
grounded.
2. If the booster battery is in another vehicle, do not allow the vehicles totouch.
3. Turn off all unnecessary electrical loads.
4. Connect the jumper cables in the exact sequence shown in the illustration.First connect one end of a jumper
cable to the positive terminal of the
discharged battery (1), then connect
the other end to the positive terminal
on the booster battery (2). Proceed toconnect one end of the other jumper
cable to the negative terminal of the
booster battery (3), then the other end
to a solid, stationary, metallic point (for
example, the engine lifting bracket)
away from the battery (4). Do not con-
nect it to or near any part that moves
when the engine is cranked.
Do not allow the jumper cables to con-
tact anything except the correct battery
terminals or the correct ground. Do not
lean over the battery when making
connections.
CAUTION
Use only a 12-volt jumper system. You can damage a 12-volt startingmotor, ignition system, and other electrical parts beyond repair by
use of a 24-volt power supply (eithertwo 12-volt batteries in series or a 24-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.
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.1VQA4001

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 while the vehicle is in motion,
store them properly.CAUTION
Your vehicle has metric threads
on the wheel studs and nuts.Make certain during wheelremoval that the same nuts that were 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 itmust be replaced.
Note that most wheel nuts donot have metric threads. Be sureto use extreme care in checkingfor thread style before installing aftermarket wheel nuts orwheels. If in doubt, consult anauthorised HYUNDAI 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” insection 9.

TOWING
F080100AFD-EA
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 (or 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 towing hooks to pull a
vehicle out of mud, sand or other con-
ditions 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.
CAUTION
Failure to place the transaxle shift
lever in N (Neutral) may cause inter-nal damage to the transaxle.HNF4019

Performing maintenance work on a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorised HYUNDAI dealer.
Working under the bonnet with the engine running is dangerous.
It becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while work-
ing under the bonnet, make cer-
tain that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before gettingnear the engine or cooling fans.WARNING - Diesel Engine
Never work on injection system with engine running or within 30
seconds after shutting off engine.
High-pressure pump, rail, injectorsand high-pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touches the body.
People using pacemakers shouldnot be within 30cm of the ECU orwiring harness within the engine
room while engine is running, since
the high currents in the electronic
engine control system produce
considerable magnetic fields.
