Driving your vehicle32 4Immobilizer indicator
(if equipped)This light illuminates when the immobiliz-
er key is inserted and turned to the ON
position to start the engine.
At this time, you can start the engine. The
light goes out after the engine is running.
In case this light goes out before you
start the engine, you must turn to the
LOCK position and restart the engine.
If this light blinks when the ignition switch
is in the ON position before starting the
engine, have the system checked by an
authorized Kia dealer.
Parking brake & brake
fluid warning Parking brake warning This light is illuminated when the parking
brake is applied with the ignition switch in
the START or ON position. The warning
light should go off when the parking
brake is released.Low brake fluid level warningIf the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the
brake fluid level immediately and add
fluid as required. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are
found, the warning light remains on or
the brakes do not operate properly.
Have it towed to any authorized Kia
dealer for a brake system inspection
and necessary repairs.To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the ignition switch
is in the ON position.
WARNING
Driving the vehicle with a brake
warning light on is dangerous. If the
brake warning light remains on,
have the brakes checked and
repaired immediately by an author-
ized Kia dealer.

Driving tips4 5BEFORE DRIVING Before entering vehicle: Be sure that all windows, outside mir-
ror(s), and outside lights are clean.
Check the condition of the tires.
Check under the vehicle for any sign of
leaks.
Be sure there are no obstacles behind
you if you intend to back up.Necessary inspections Fluid levels, such as engine oil, engine
coolant, brake fluid, and washer fluid
should be checked on a regular basis,
with the exact interval depending on the
fluid. Further details are provided in
Section 7, Maintenance.
Before starting Close and lock all doors.
Position the seat so that all controls are
easily reached.
Adjust the inside and outside rearview
mirrors.
Be sure that all lights work.
Check all gauges.
Check the operation of warning lights
when the ignition switch is turned to
the ON position.
Release the parking brake and make
sure the brake warning light goes out.
For safe operation, be sure you are famil-
iar with your vehicle and its equipment.
WARNING
- Driving under
the influence of alcohol or
drugs
Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgement. Driving
while under the influence of drugs
is as dangerous or more dangerous
than driving drunk.
You are much more likely to have a
serious accident if you drink or take
drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.

Driving tips
Driving at night Because night driving presents more
hazards than driving in the daylight, here
are some important tips to remember:
Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
Adjust your mirrors to reduce the glare
from other driver's headlights.
Keep your headlights clean and prop-
erly aimed on vehicles not equipped
with the automatic headlight aiming
feature. Dirty or improperly aimed
headlights will make it much more diffi-
cult to see at night.
Avoid staring directly at the headlights
of oncoming vehicles. You could be
temporarily blinded, and it will take
several seconds for your eyes to read-
just to the darkness.
Driving in the rain Rain and wet roads can make driving
dangerous, especially if you’re not pre-
pared for the slick pavement. Here are a
few things to consider when driving in the
rain:
A heavy rainfall will make it harder to
see and will increase the distance
needed to stop your vehicle, so slow
down.
Keep your windshield wiping equip-
ment in good shape. Replace your
windshield wiper blades when they
show signs of streaking or missing
areas on the windshield.
If your tires are not in good condition,
making a quick stop on wet pavement
can cause a skid and possibly lead to
an accident. Be sure your tires are in
good shape.
Turn on your headlights to make it eas-
ier for others to see you.
Driving too fast through large puddles
can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
If you believe you may have gotten
your brakes wet, apply them lightly
while driving until normal braking oper-
ation returns.
Winter driving We recommend that you carry emer-
gency equipment, including a window
scraper, windshield de-icer, a bag of
sand or salt, flares, a small shovel and
jumper cables.
Make sure you have sufficient ethyl-
ene-glycol coolant in the radiator.
Check the battery condition and
cables. Cold temperatures reduce the
output capability of any battery, so it
must be in excellent condition to pro-
vide enough winter starting power.
Make sure the engine oil viscosity is
suitable for cold weather.
Check the ignition system for loose
connections and damage.
Use antifreeze-formulated windshield
washer fluid. (Do not use engine
coolant antifreeze.)
Do not use the parking brake if it might
freeze. When parking, shift to 1 (First)
or R (Reverse) with a manual transaxle
or P (Park) with an automatic transaxle
and block the rear wheels.

Driving tips
When you are ready to leave after
parking on a hill 1. With the automatic transaxle in P
(Park), apply your brakes and hold the
brake pedal down while you:

and

2. Slowly remove your foot from the
brake pedal.
3. Drive slowly forward until the trailer is
clear of the chocks.
4. Stop and have someone pick up and
store the chocks.Maintenance when trailer towing Your vehicle will need service more often
when you regularly pull 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 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 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 hitch nuts
and bolts should be tight.
✽ ✽
NOTICE• 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 transaxle fluid
more frequently.
• If your vehicle is not equipped with
the air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.
If you do decide to pull a trailerHere are some important points if you
decide to pull a trailer:
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. If you feel that
the trailer is adversely affecting the move-
ment of your vehicle, reduce your speed,
avoid uneven or winding roads, avoid
roads with steep grades, and/or lighten
your trailer load.
