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.
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 permissible
trailer tongue load. After you've loaded
your trailer, weigh the trailer and then the
tongue, separately, to see if the weightsare within specification. 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.
Never exceed the maximum weight limits of the trailer or trail-
er towing equipment. Improper
loading can result in damage to
your vehicle and/or personal
injury. Check weights and loading
at a commercial scale or public
weighbridge.
An improperly loaded trailer can cause loss of vehicle control.

Driving your vehicle
This section will guide you in the proper
loading of your vehicle and/or trailer, to
keep your loaded vehicle weight within its
design rating capability, with or without a
trailer. Properly loading your vehicle will
provide maximum return of the vehicle
design performance. Before loading your
vehicle, familiarize yourself with the fol-
lowing terms for determining your vehi-
cle's weight ratings, with or without a
trailer, from the vehicle's specifications
and the certification label: Base kerb weight
This is the weight of the vehicle including a full tank of fuel and all standard equip-
ment. It does not include passengers,
cargo, or optional equipment.
Vehicle kerb weight
This is the weight of your new vehicle
when you picked it up from your dealer
plus any aftermarket equipment.
Cargo weight
This figure includes all weight added to
the Base Kerb Weight, including cargoand optional equipment.GAW (Gross axle weight)
This is the total weight placed on each
axle (front and rear) - including vehicle
kerb weight and all payload.
GAWR (Gross axle weight rating)
This is the maximum allowable weight
that can be carried by a single axle (front
or rear). These numbers are shown on
the certification label.
The total load on each axle must never
exceed its GAWR.
GVW (Gross vehicle weight)
This is the Base Kerb Weight plus actual
Cargo Weight plus passengers.
GVWR (Gross vehicle weight rat- ing)
This is the maximum allowable weight of
the fully loaded vehicle (including all
options, equipment, passengers and
cargo). The GVWR is shown on the cer-tification label.

WARNING -
Vehicle weight
The gross axle weight rating
(GAWR) and the gross vehicle
weight rating (GVWR) for your vehi-
cle are on the certification label
attached to the driver's (or front
passenger’s) door. Exceedingthese ratings can cause an acci-
dent or vehicle damage. You can
calculate the weight of your load byweighing the items (and people)
before putting them in the vehicle.
Be careful not to overload your
vehicle.

What to do in an emergency
Do not take this vehicle through anautomatic car wash whilst the com- pact spare tyre is installed.
Do not use tyre chains on the com- pact spare tyre. Because of the
smaller size, a tyre chain will not fit
properly. This could damage the
vehicle and result in loss of thechain.
The compact spare tyre should not be installed on the front axle if the
vehicle must be driven in snow or
on ice.
Do not use the compact spare tyre on any other vehicle because thistyre has been designed especially
for your vehicle.
The compact spare tyre’s tread life is shorter than a regular tyre.
Inspect your compact spare tyre
regularly and replace worn com-
pact spare tyres with the same sizeand design, mounted on the samewheel. The compact spare tyre should not
be used on any other wheels, nor
should standard tyres, snow tyres,
wheel covers or trim rings be used
with the compact spare wheel. Ifsuch use is attempted, damage tothese items or other car compo-
nents may occur.
Do not use more than one tempo- rary spare tyre at a time.
Do not tow a trailer whilst the tem- porary spare tyre is installed.

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.
