your vehicle, refer to "Weight of the

trailer" on page 5-197 that appears later

in this section.

Remember that trailering is different

than just driving your vehicle by itself.

Trailering means changes in handling,

durability, and fuel economy. Successful,

-

safe trailering requires correct equip

ment, and it has to be used properly.

-

This section contains many timetested,

important trailering tips and safety rules.

Many of these are important for your

safety and that of your passengers.

Please read this section carefully before

you pull a trailer.

Load-pulling components such as the

engine, transmission, wheel assemblies,

and tires are forced to work harder

against the load of the added weight.

The engine is required to operate at rela

tively higher speeds and under greater

loads. This additional burden generates

extra heat. The trailer also considerably

adds wind resistance, increasing pulling

requirements.

NOTICE

僅 The technically permissible maximum

load on the rear axle(s) may be

exceeded by not more than 15 % and

the technically permissible maximum

laden mass of the vehicle may be

exceeded by not more than 10 % or

100 kg (220.4 lbs), whichever value is

lower. In this case, do not exceed 100

km/h (60 mph) for vehicle of category

M1 or 80 km/h (50 mph) for vehicle of

category N1.

-

僅 When towing a trailer, the additional

load imposed at the trailer coupling

device may cause the rear tire maxi

-

mum load ratings to be exceeded, but

not by more than 15%. In such a case,

do not exceed 100km/h (60 miles),

and the rear tire pressure should be at

least 20 kPa above the tire pressure(s)

as recommended for normal use (i.e.

without a trailer attached).

CAUTION

Pulling a trailer improperly can damage

your vehicle and result in costly repairs

not covered by your warranty. To pull a

trailer correctly, follow the advice in this

section.

Hitches

It's important to have the correct hitch

equipment. Crosswinds, large trucks

going by, and rough roads are a few rea

sons why you'll need the right hitch.

Here are some rules to follow:

-

僅 Do you have to make any holes in the

body of your vehicle when you install

a trailer hitch? If you do, then be sure

to seal the holes later when you

remove the hitch.

If you don't seal them, deadly carbon

monoxide (CO) from your exhaust

can get into your vehicle, as well as

dirt and water.

僅 The bumpers on your vehicle are not

intended for hitches. Do not attach

rental hitches or other bumper-type

hitches. Use only a frame-mounted

hitch that does not attach to the

bumper.

an experienced, competent trailer shop

for this work.

Driving with a trailer

Towing a trailer requires a certain

amount of experience. Before setting

out for the open road, you must get to

know your trailer. Acquaint yourself with

the feel of handling and braking with the

added weight of the trailer. And always

keep in mind that the vehicle you are

driving is now a good deal longer and

not nearly so responsive as your vehicle

is by itself.

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 hitch.

Instructions about safety chains may be

provided by the hitch 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 drag on the ground.

Before you start, check the trailer hitch

and platform, safety chains, electrical

connector(s), lights, tires and mirror

adjustment. If the trailer has electric

brakes, start your vehicle and trailer

moving and then apply the trailer brake

controller by hand to be sure the brakes

are working. This lets you check your

electrical connection at the same time.

Trailer brakes

If your trailer is equipped with a braking

system, make sure it conforms to your

Kia recommends to visit an authorized

WARNING

Failure to use an approved trailer wiring

harness could result in damage to the

vehicle electrical system and/or personal

injury.

Making turns

When you're turning with a trailer, make

wider turns than normal. Do this so your

trailer won't strike soft shoulders, curbs,

road signs, trees, or other objects. Avoid

jerky or sudden maneuvers. Signal well

in advance.
