Driving your vehicle
When you are ready to leave after
parking on a hill
1. With the manual transmission inNeutral, apply your brakes and
hold the brake pedal down while
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 tow- ing
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particularattention to include engine oil, 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 hitch. Follow the mainte-nance schedule that accompanied
your trailer and check it periodically.
Preferably, conduct the check at the
start of each day’s driving. Most
importantly, all hitch nuts and boltsshould be tight.
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 run-
ning, the vehicle can move sud-
denly. You or others could be
seriously or fatally injured.

If you do decide to pull a trail- er
Here are some important points if
you decide to pull a trailer:
Consider using a sway control. Youcan ask a hitch dealer about sway control.
Do not do any towing with your vehicle during 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 transmission
damage.
When towing a trailer, we recom- mend that you consult an author-
ized HYUNDAI dealer on addition-
al requirements such as a towingkit, etc.
Always drive your vehicle at a mod- erate speed (Max speed for stan-
dard trailer is 80 km/h (50 mph)). ❇ Special trailer 100 km/h (60
mph) is allowed but trailer need
special approval from TÜV. On a long uphill grade, do not
exceed 70 km/h (45 mph) or the
posted towing speed limit,
whichever is lower.
Fuel consumption will increase due to the additional required power to
tow trailer and additional trans-
portation weight at the trailer.
To prevent vehicle damage :
Due to higher load during
trailer usage, overheating
might occur in hot days or
during uphill driving. If the
coolant gauge indicates over-
heating, switch off the A/C
and stop the vehicle in a safe
area to cool down the engine.
When towing check transmis-
sion fluid more frequently.
If your vehicle is not equipped
with the air conditioner, youshould install a condenser fan
to improve engine perform-
ance when towing a trailer.

Trailer weight
How heavy can a trailer safely be? It
should never weigh more than the
maximum 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, alti-
tude, road grades, outside tempera-
ture and how often your vehicle is
used to pull a trailer are all important.
The ideal trailer weight can also
depend on any special equipment
that you have on your vehicle.
Tongue load
The tongue load of any trailer is an
important weight to measure
because it affects the total gross
vehicle weight (GVW) of your vehi-
cle. This weight includes the curb
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 add thetongue load to the GVW because
your vehicle will also be carrying that
weight.The trailer tongue should weigh a
maximum of 10% of the total loaded
trailer weight, 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 weights are
proper. If they aren’t, you may be
able to correct them simply by mov-
ing some items around in the trailer.

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 capa-
bility, with or without a trailer.
Properly loading your vehicle will
provide maximum return of the vehi-
cle design performance. Before load-
ing your vehicle, familiarize yourself
with the following terms for determin-
ing your vehicle's weight ratings, with
or without a trailer, from the vehicle's
specifications and the certificationlabel:
Base curb weight
This is the weight of the vehicle including a full tank of fuel and all
standard equipment. It does not
include passengers, cargo, or option-al equipment.
Vehicle curb weight
This is the weight of your new vehicle
when you picked it up from your deal-
er plus any aftermarket equipment.
Cargo weight
This figure includes all weight added
to the Base Curb Weight, includingcargo and optional equipment.
GAW (Gross axle weight)
This is the total weight placed on each axle (front and rear) - including
vehicle curb weight and all payload.
GAWR (Gross axle weight rat- ing)
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 Curb Weight plus
actual Cargo Weight plus passen-
gers.
Take the following precautions:
Never load a trailer with more weight in the rear than in the
front. The front should be
loaded with approximately60% of the total trailer load;the rear should be loaded with
approximately 40% of the totaltrailer load.
Never exceed the maximum weight limits of the trailer or
trailer towing equipment.
Improper loading can result in
damage to your vehicle and/or
personal injury. Checkweights and loading at a com-
mercial scale or highway
patrol office equipped withscales.
An improperly loaded trailer
can cause loss of vehicle con-
trol.

GVWR (Gross vehicle weight rating)
This is the maximum allowable
weight of the fully loaded vehicle
(including all options, equipment,
passengers and cargo). The GVWR
is shown on the certification label.
Overloading
A locking differential, if equipped, is
for the rear wheel differential only.
The features of this locking differen-
tial are described below:
Just as with a conventional differen-
tial, the wheel on one side is allowed
to turn at a different speed from thewheel on the other side when the
vehicle is cornering. The difference
between the locking differential and a
conventional differential is that if the
wheel on one side of the vehicle
loses traction, a greater amount oftorque is applied to the rear wheel on
the other side to improve traction.Information
In a stationary position, the LD
(Locking Differential) will operate
when the difference of the revolution
speed between the rear right wheel
and the rear left wheel occurs.
i
The gross axle weight rating
(GAWR) and the gross vehicle
weight rating (GVWR) for your
vehicle are on the certification
label attached to the driver's (or
front passenger’s) door.Exceeding these ratings can
cause an accident or vehicle
damage. You can calculate the
weight of your load by weighing
the items (and people) before
putting them in the vehicle. Be
careful not to overload your
vehicle.

Driving your vehicle
The following procedures can be
used to confirm that the locking dif-
ferential is functioning properly:
(1) Position the vehicle so that onewheel is on a dry paved surface
and the other on ice, snow, mud,
etc. Drive the vehicle, and
observe the operation of the lock-
ing differential. The vehicle
should not become stuck if the
differential is functioning properly.
(2) Depress the accelerator pedal
gradually, and then when traction
is good, depress it forcefully. If
the vehicle accelerates well, the
differential is functioning properly.
Information
Usually a locking differential will
operate and release automatically but
occasionally it may not release auto-
matically.
At this time you will feel the tire is
dragged when you are driving or cor-
nering. You can release it manually by
slightly turning the steering wheel
right and left while the vehicle is mov-
ing slowly.
i
Never start the engine with
the gearshift lever placed in
the forward or reverse whileone of the rear wheels is
jacked up and the other in
contact with the ground;
doing so may cause the vehi-
cle to jump forward.
If one of the rear wheels
begins to spin in mud, snow,
etc., the vehicle can some-
times be driven out bydepressing the accelerator
pedal further; however, avoid
running the engine continu-
ously at high rpm because
doing so could damage the
locking differential.
