Driving downhill
Going downhill can be considerably more
dangerous than driving uphill. When off-
roading takes you downhill, you’ll want to
consider many of the same things you
thought about before you went uphill. As
a brief reminder, those include:
• How steep is the downhill? Will I be
able to maintain vehicle control?
• What’s the surface like? Smooth?
Rough? Slippery? Hard-packed dirt?
Gravel?
• Are there hidden surface obstacles?
Ruts? Logs? Boulders?
• What’s at the bottom of the hill? Is
there a hidden creek bank or even a
river bottom with large rocks?
• Have changes in the weather condi-
tions and their effect on the terrain
since you went uphill made your task
more difficult?
Once you have decided that you can go
down a hill safely, try to keep your vehicle
headed straight down, and use a low
gear. This way, engine braking can help
your brakes so they won’t have to do all
the work. Descend slowly, keeping your
vehicle under control at all times.Avoid turns that take you across the
incline of the hill. A hill that’s not too
steep to drive down may be too steep to
drive across. You could roll over if you
don’t drive straight down.
Never go downhill with the clutch pedal
depressed. This is called “free-wheeling.”
Your brakes will have to do all the work
and could overheat and fade.
If your wheels lock up during downhill
braking, you may feel the vehicle starting
to slide sideways. To regain your direc-
tion, just ease off the brakes and steer to
keep the front of the vehicle pointing
straight downhill.
WARNING- Braking
Heavy braking when going down a
hill can cause your brakes to over-
heat and fade. This could cause
loss of control and a serious acci-
dent. Apply the brakes lightly when
descending a hill and use a low
gear to keep vehicle speed under
control.
WARNING-Wheel locking
Avoid braking so hard that you lock
the wheels when going downhill. If
your front wheels are locked, you
can’t steer your vehicle.
WARNING-Downhill
Before beginning to go downhill, it
is critical that you ensure that no
cargo can shift forward while you
are heading downhill. Such shifting
could either endanger you and your
occupants, or interfere with your
ability to control the vehicle.

Driving tips
Stalling downhill
Stalling is much more likely to happen
going uphill. But if it happens going
downhill, here’s what to do.
• Stop your vehicle by applying the
brakes. Then apply the parking brake.
• Move the shift lever to P (Park) in auto-
matic transmission or shift to N
(Neutral) in manual transmission and,
while still braking, restart the engine.
• Shift back to a low gear, release the
parking brake, and drive straight down.
• If the engine won’t start, get out and
seek help. Exit on the uphill side of the
vehicle and stay clear of the path the
vehicle would take if it rolled downhill.
Driving across an incline
Sooner or later, an off-road trail will prob-
ably go across the incline of a hill. If this
happens, you have to decide whether or
not to try to drive across the incline. Here
are some things to consider:
• A hill that can be driven straight up or
down may be too steep to drive across.
When you go straight up or down a hill,
the length of the wheel base (the dis-
tance from the front wheels to the rear
wheels) reduces the likelihood the
vehicle will tumble end over end. But
when you drive across an incline, the
much narrower track width (the dis-
tance between the left and right
wheels) may not prevent the vehicle
from tilting and rolling over. Also, driv-
ing across an incline puts more weight
on the downhill wheels. This could
cause a downhill slide or a rollover.
• Surface conditions can be a problem
when you drive across a hill. Loose
gravel, muddy spots, or even wet grass
can cause your tires to slip sideways. If
the vehicle slips sideways, it can hit
something that will tip it (a rock, a rut,
etc.) and cause it to roll over.• Hidden obstacles can make the steep-
ness of the incline even worse. If you
drive across a rock with the uphill
wheels, or if the downhill wheels drop
into a rut or depression, your vehicle
can tilt even more.
For reasons like these, you need to
decide carefully whether or not to try to
drive across an incline. Just because the
trail goes across the incline doesn’t
mean you have to drive it.
WARNING- Roll over
Driving across an incline that’s too
steep will make your vehicle roll
over. You could be seriously or
fatally injured. If you have any
doubt about the steepness of the
incline, don’t drive across it. Find
another route instead.

Driving tips
Hard-packed snow and ice offer the
worst tire traction. On these surfaces, it’s
very easy to lose control. On wet ice, for
example, the traction is so poor that you
will even have difficulty accelerating. And
if you do get moving, poor steering and
difficult braking can easily cause you to
slide out of control.Driving in water
Light rain causes no special off-road driv-
ing problems. However, heavy rain can
cause flash flooding, and flood waters
demand extreme caution.
Find out how deep the water is before
you drive through it. If it’s deep enough to
cover your wheel bearing hubs, axles, or
exhaust pipe, don’t try it, You probably
won’t get through. Also, water that deep
can damage your axle and other vehicle
parts.
If the water isn’t too deep, then drive
through slowly. At fast speeds, water can
splash on your ignition system and your
vehicle can stall. Stalling can also occur
if your tailpipe goes underwater. As long
as your tailpipe is underwater, you will
not be able to start your engine. When
you go through water, remember that it
may take you longer to stop when your
brakes are wet.
If you have driven through water that was
deep enough to cover your wheel bear-
ing hubs, it may be a good idea to have
an Authorized Kia dealer or other com-
petent service center repack your front
wheel bearings and examine your rear-
end fluid for evidence of water.CAUTION
• In case of loss of traction in mud,
loose soil, or sand, turn the steer-
ing wheel rapidly from side-to-
side. This can help generate addi-
tional traction.
• Do not gun the engine. This will
cause the tires to spin and dig
down, not forward, and could
bury the vehicle to the frame.
Smooth, easy power is better
than too much power.
WARNING- Frozen sur-
faces
Driving on frozen lakes, ponds or
rivers can be dangerous.
Underwater springs, currents under
the ice, or sudden thaws can weak-
en the ice. Your vehicle could fall
through the ice and you and your
passengers could drown. Drive
your vehicle on safe surfaces only.

GCWR (Gross Combined
Weight Rating)
This is the maximum allowable
weight of the vehicle and the loaded
trailer - including all cargo and pas-
sengers - that the vehicle can handle
without risking damage. (Important :
The towing vehicle's braking system
is rated for operation at GVWR, not
GCWR. Separate functional brakes
should be used for safe control of
towed vehicles and for trailers weigh-
ing an 750kg (1,653 lbs).) The GCW
must never exceed the GCWR.
Maximum Trailer Weight
This is the highest possible weight of
a fully loaded trailer the vehicle can
tow. It assumes a vehicle with only
mandatory options, no cargo, and a
driver. The weight of other optional
equipment, passengers and cargo in
your vehicle will reduce the maxi-
mum trailer weight your vehicle can
tow.
Calculating the load your vehi-
cle can tow
1. Use the appropriate maximum
GCWR chart (in the Weight of the
Trailer section in this chapter) for
your type of drive system and
transmission.
2. Weigh your vehicle.
3. Subtract the weight of your vehicle
from the maximum GCWR in the
chart. This is the maximum trailer
weight your vehicle can tow. It
must be below the maximum trail-
er weight shown in the chart. Note
that the maximum trailer weight
your vehicle can tow depends on
the total weight of any cargo, pas-
sengers and available equipment
in the vehicle.

TRAILER TOWING
To identify what the vehicle trailering
capacity is for your vehicle, you should
refer to the chart on this page.
WARNING- Towing a trail-
er
If you don't use the correct equip-
ment and drive properly, you can
lose control when you pull a trailer.
For example, if the trailer is too
heavy, the brakes may not work well
- or even at all. You and your pas-
sengers could be seriously or fatal-
ly injured. Pull a trailer only if you
have followed all the steps in this
section.
WARNING- Weight limits
Before towing, make sure the total
trailer weight, gross combination
weight, gross vehicle weight, gross
axle weight and trailer tongue load
are all within the limits.

NOTICE
• For definitions of terms used in this table and instructions on how to calculate
your vehicle load, refer to Weight of the Vehicle in this chapter.
• The combined weight of the completed towing vehicle and the loaded trailer must
not exceed the GCWR.
• When towing maximum loads under high outside temperatures and/or on steep
grades, the A/C system may cycle on and off to protect the engine from overheat-
ing. This may result in a temporary increase of interior temperature.
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.

Remember that trailering is different than
just driving your vehicle by itself.
Trailering causes major changes in han-
dling, durability, and fuel economy.
Successful, safe trailering requires cor-
rect equipment, and cautious driving.
This section contains many time-tested,
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 relatively
higher speeds and under greater loads.
This additional burden generates extra
heat. The trailer also adds considerably
to wind resistance, increasing the pulling
requirements.If you do decide to pull a trailer
Here are some important points if you
decide to pull a trailer:
• State, provincial, county and municipal
government have varying trailering
laws. Make sure your hitch, mirrors,
lights and wiring arrangements are
legal, not only where you live, but also
where you’ll be driving. A good source
for this information is state or local law
enforcement agencies.
• Consider using a sway control. You can
ask a hitch dealer about sway control.
• After your odometer indicates 800 km
(500 miles) or more, you can tow a
trailer. For the first 800 km (500 miles)
that you tow a trailer, don’t drive over
80 km/h (50 mph) and don’t make
starts at full throttle. This helps your
engine and other parts of your vehicle
“wear” in at the heavier loads.
• Always drive your vehicle at a moder-
ate speed (less than 100 km/h (60
mph)).
• On a long uphill grade, do not exceed
70 km/h (45 mph) or the posted towing
speed limit, whichever is lower.
• The important considerations have to
do with weight:
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
much 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.

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 man-
ufacturer’s recommendation for attaching
safety chains. Always leave just enough
slack so you can turn with your trailer.
And, never allow safety chains to drag on
the ground.
Trailer brakes
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
loaded, then it needs its own brakes and
they must be adequate. Be sure to read
and follow the instructions for the trailer
brakes so you’ll be able to install, adjust
and maintain them properly.
• Don’t tap into your vehicle's brake sys-
tem.
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.
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 mov-
ing and then apply the trailer brake con-
troller by hand to be sure the brakes are
working. This lets you check your electri-
cal connection at the same time.
During your trip, check occasionally to be
sure that the load is secure, and that the
lights and any trailer brakes are still work-
ing.
WARNING - Trailer brakes
Do not use a trailer with its own
brakes unless you are absolutely
certain that you have properly set
up the brake system. This is not a
task for amateurs. Use an experi-
enced, competent trailer shop for
this work.

Driving tips

Do not connect a trailer lighting system
directly to your vehicle’s lighting system.
Use only an approved trailer wiring har-
ness.
Your Authorized Kia Dealer can assist
you in installing the wiring harness.Driving on grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 70 km/h (45
mph) to reduce the possibility of engine
and transmission overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transmission,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimize heat build up
and extend the life of your transmission.
If you have a manual transmission, drive
in fourth gear (or, as you need to, a lower
gear).
WARNING
Failure to use an approved trailer
wiring harness could result in dam-
age to the vehicle electrical system
and/or personal injury.
CAUTION
• When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge to
ensure the engine does not over-
heat. If the needle of the coolant
temperature gauge moves across
the dial towards “H” (HOT), pull
over and stop as soon as it is safe
to do so, and allow the engine to
idle until it cools down. You may
proceed once the engine has
cooled sufficiently.
• You must decide driving speed
depending on trailer weight and
uphill grade to reduce the possi-
bility of engine and transmission
overheating.
