placing the engine start/stop button switch to the ON position and by se‐
lecting 'User Settings', 'Driving Assist',
and 'Autonomous Braking System'. The AEB deactivates, when the driver can‐
cels the system setting.
The warning light illuminates on the LCD display, when youcancel the AEB system.
The driver can monitor the AEBON/OFF status on the LCD display.

ECONOMICAL OPERATION
Your vehicle's fuel economy depends mainly on your style of driving, where
you drive and when you drive.
Each of these factors affects how
many kilometers (miles) you can get from a liter (gallon) of fuel. To operate
your vehicle as economically as possi‐
ble, use the following driving sugges‐ tions to help save money in both fuel
and repairs: • Drive smoothly. Accelerate at a mod‐ erate rate. Do not make "jack-rabbit"
starts or full-throttle shifts and maintain a steady cruising speed. Do
not race between stop lights. Try to
adjust your speed to the traffic so
you do not have to change speeds
unnecessarily. Avoid heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid un‐
necessary braking. This also reduces
brake wear.
• Drive at a moderate speed. The fast‐ er you drive, the more fuel your vehi‐cle uses. Driving at a moderate
speed, especially on the highway, is
one of the most effective ways to re‐
duce fuel consumption. • Do not "ride" the brake or clutch ped‐
al. This can increase fuel consumption
and also increase wear on these com‐
ponents. In addition, driving with your
foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may lead to more serious consequences.
• Take care of your tires. Keep them inflated to the recommended pres‐
sure. Incorrect inflation, either too
much or too little, results in unneces‐
sary tire wear. Check the tire pres‐ sures at least once a month.
• Be sure that the wheels are aligned correctly. Improper alignment can re‐
sult from hitting curbs or driving too
fast over irregular surfaces. Poor alignment causes faster tire wear
and may also result in other prob‐
lems as well as greater fuel con‐
sumption.
• Keep your vehicle in good condition. For better fuel economy and reducedmaintenance costs, maintain your ve‐
hicle in accordance with the mainte‐
nance schedule in Chapter 9, Mainte‐
nance. If you drive your vehicle in se‐
vere conditions, more frequent main‐ tenance is required (see Chapter 9,
Maintenance for details). • Keep your vehicle clean. For maxi‐
mum service, your vehicle should be
kept clean and free of corrosive ma‐ terials. It is especially important that
mud, dirt, ice, etc. not be allowed to
accumulate on the underside of the
vehicle. This extra weight can result
in increased fuel consumption and al‐ so contribute to corrosion.
• Travel lightly. Do not carry unneces‐ sary weight in your vehicle. Weight
reduces fuel economy.
• Do not let the engine idle longer than necessary. If you are waiting (and notin traffic), turn off your engine and
restart only when you're ready to go.
• Remember, your vehicle does not re‐ quire extended warm-up. After the
engine has started, allow the engine
to run for 10 to 20 seconds prior to placing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warmup period.
• Do not "lug" or "over-rev" the engine. Lugging is driving too slowly in too
high a gear resulting engine bucking.
If this happens, shift to a lower gear. Over-revving is racing the engine be‐
yond its safe limit. This can be avoi‐
ded by shifting at the recommended
speeds.

Use approved window washer
anti-freeze in system
To keep the water in the window wash‐er system from freezing, add an ap‐
proved window washer anti-freeze sol‐
ution in accordance with instructions on the container. Window washer anti-
freeze is available from an authorized
Kia dealer and most auto parts outlets. Do not use engine coolant or other
types of anti-freeze as these may
damage the paint finish.
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged posi‐ tion. This is most likely to happen when
there is an accumulation of snow or ice
around or near the rear brakes or if the brakes are wet. If there is a risk the
parking brake may freeze, apply it only
temporarily while you put the shift lev‐ er in P (Automatic Transaxle / Dual
clutch transmission) or in first or re‐
verse gear (manual transaxle) and block
the rear wheels so the vehicle cannot roll. Then release the parking brake.
Don't let ice and snow
accumulate underneath
Under some conditions, snow and ice can build up under the fenders and in‐
terfere with the steering. When driving
in severe winter conditions where this may happen, you should periodically
check underneath the vehicle to be sure
the movement of the front wheels and the steering components is not ob‐
structed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropriate emergency equipment. Some of the
items you may want to carry include
tire chains, tow straps or chains, flash‐ light, emergency flares, sand, shovel,
jumper cables, window scraper, gloves,
ground cloth, coveralls, blanket, etc.

IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. Be sure the shift lever is in N (Neu‐tral) or P (Park) and the emergency
brake is set.
2. Check the battery connections to be sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you
operate the starter, the battery is
discharged.
4. Check the starter connections to be sure they are securely tightened.
5. Do not push or pull the vehicle to start it. See instructions for L
