Parking Brake & Brake
Fluid Warning Light
This warning light illuminates:
Once you set the ignition switch or Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3seconds
- It remains on if the parking brake is applied.
When the parking brake is applied.
When the brake fluid level in the reservoir is low.
- If the warning light illuminateswith the parking brake released, it
indicates the brake fluid level in
reservoir is low. If the brake fluid level in the reservoir
is low:
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 (For
more details, refer to "Brake Fluid"
in chapter 7).
Then check all brake components for fluid leaks. If any leak on the
brake system is still found, the
warning light remains on, or the
brakes do not operate properly, do
not drive the vehicle.
In this case, have your vehicle
towed to an authorized Kia dealer
and inspected. Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems should fail.
With only one of the dual systems
working, more than normal pedal
travel and greater pedal pressure are
required to stop the vehicle.
Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
If the brakes fail while you are driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.

washer fluid should be checked on a
regular basis, with the exact interval
depending on the fluid. Further
details are provided in chapter 7,

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a
loss of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1.Pull off the road and stop as soonas it is safe to do so.
2.Place the shift lever in P (automat- ic transaxle) and set the parking
brake. If the air conditioning is on,
turn it off.
3.If engine coolant is running out under the vehicle or steam is com-
ing out from underneath the hood,
stop the engine. Do not open the
hood until the coolant has stopped
running or the steaming has
stopped. If there is no visible loss
of engine coolant and no steam,
leave the engine running and
check to be sure the engine cool-
ing fan is operating. If the fan is not
running, turn the engine off. 4.Check to see if the water pump
drive belt is missing. If it is not
missing, check to see that it is
tight. If the drive belt seems to be
satisfactory, check for coolant leak-
ing from the radiator, hoses or
under the vehicle. (If the air condi-
tioning had been in use, it is nor-
mal for cold water to be draining
from it when you stop).
5.If the water pump drive belt is bro- ken or engine coolant leaks, stop
the engine immediately and call
the nearest authorized Kia dealer
for assistance. 6.If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7.Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized Kia dealer for
assistance.
Serious loss of coolant indicates
there is a leak in the cooling system
and this should be checked as soon
as possible by an authorized Kia
dealer.
WARNING - Under the hood
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts.
WARNING - Radiator cap
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of
the opening and cause serious
burns.

627
What to do in an emergency
If the car is being towed with allfour wheels on the ground, it can
be towed only from the front. Be
sure that the transaxle is in neutral.
Be sure the steering is unlocked by
placing the ignition switch in the
ACC position. A driver must be in
the towed vehicle to operate the
steering and brakes. When towing your vehicle in an
emergency without wheel dollies :
1.Set the ignition switch in the ACC
position.
2.Place the transaxle shift lever in N (Neutral).
3.Release the parking brake.
CAUTION - Towing gear position
Always place the transaxle shiftlever in Neutral (N) when towingyour vehicle. Failure to place thetransaxle shift lever in N(Neutral) may cause internaldamage to the transaxle.
CAUTION - Automatic
transaxle
To avoid serious damage to the automatic transaxle, limitthe vehicle speed to 15 km/h(10 mph) and drive less than1.5 km (1 mile) when towing.
Before towing, check the auto- matic transaxle for fluid leaksunder your vehicle. If the auto-matic transaxle fluid is leak-ing, a flatbed equipment ortowing dolly must be used.
