(6 mph) when a vehicle is braking
on a split-mu road. The split-mu
road is made of surfaces which
have different friction forces.
WARNING
•The Vehicle Stability Managementsystem is not a substitute for safedriving practices but a supplemen‐tary function only. It is the respon‐sibility of the driver to alwayscheck the speed and the distanceto the vehicle ahead. Always holdthe steering wheel firmly whiledriving.

•Driving with varying tire or wheelsizes may cause the VSM systemto malfunction. When replacingtires, make sure they are thesame size as your original tires.
Hill-start assist control (HAC) (if
equipped)
A vehicle has the tendency to slip back
on a steep hill when it starts to go af‐ ter stopping. The Hill-start Assist Con‐
trol (HAC) prevents the vehicle from
slipping back by operating the brakes automatically for about 1~2 seconds.
The brakes are released when the ac‐
celerator pedal is depressed or after about 1~2 seconds.
WARNING
The HAC is activated only for about1~2 seconds, so when the vehicle isstarting off always depress the ac‐celerator pedal.

The BSD (Blind spot detection) system
uses a radar sensor to alert the driver while driving.
It senses the rear side territory of the
vehicle and provides information to the
driver. 1. BSD (Blind spot detection)
Warning range is dependent on
your vehicle speed. However, if the
speed of your vehicle is faster by
10 km/h or more than other nearby
vehicles, the warning is not operat‐
ed.
2. LCA (Lane change assist) When vehicles are approaching toyour vehicle at high speed, the
warning is operated.
3. RCTA (Rear cross traffic alert) When your vehicle moves back‐
ward, the sensor detects approach‐
ing vehicles to the left or right side
direction and warning is operated.
WARNING
•Always check the road conditionwhile driving for unexpected situa‐tions even though the BSD (Blindspot detection) system is operat‐ing.
•BSD (Blind spot detection) systemis a system made for convenience.Do not solely rely on the systembut always pay attention to drivesafely.

Driving your vehicle

• Use your air conditioning sparingly.The air conditioning system is oper‐
ated by engine power so your fuel economy is reduced when you use it.
• Open windows at high speeds can re‐ duce fuel economy.
• Fuel economy is less in crosswinds and headwinds. To help offset some
of this loss, slow down when driving
in these conditions.
Keeping a vehicle in good operating
condition is important both for econo‐
my and safety. Therefore, we recom‐ mend that the system be serviced by
an authorized Kia dealer.
WARNING
nEngine off during motion
Never turn the engine off to coastdown hills or anytime the vehicle isin motion. The power steering andpower brakes will not function prop‐erly without the engine running. In‐stead, keep the engine on and down‐shift to an appropriate gear for en‐gine braking effect. In addition, turn‐
