Upon opening the doors or pressing the ENGINE START/STOP button, your Kia Carnival automatically
scans for the presence of the authorized smart key within the cabin.
If the smart key is not detected inside the vehicle, the "
" indicator will illuminate,
accompanied by a "Key is not in the vehicle" alert on the instrument cluster and LCD display. If all doors are
closed, an audible chime will sound for 5 seconds. Please note that this warning will cease once the vehicle begins
moving; always ensure the smart key is securely in your possession before departing.
WARNING
The engine will only start if the smart key is detected within the Kia Carnival cabin. To prevent
unintended engine activation or accidental vehicle movement, never allow children or individuals unfamiliar with the
vehicle's operation to interact with the ENGINE START/STOP button or related controls while the key is present.
CAUTION
Should the engine stall while the Kia Carnival is in motion, avoid shifting the transmission into
the P (Park) position. If traffic and road safety permit, you may shift to N (Neutral) while the vehicle is still
rolling and press the ENGINE START/STOP button to attempt an immediate engine restart.
NOTICE
- If the smart key battery is depleted or the key is malfunctioning, you can start the engine by pressing the
ENGINE START/STOP button directly with the body of the smart key. Ensure the key contacts the button at a right
angle for optimal signal transmission.

- If the stop lamp fuse is blown, normal starting procedures may be disabled. In this event, replace the fuse
immediately. If replacement is not possible, you may attempt to start the engine by pressing and holding the
ENGINE START/STOP button for 10 seconds while the ignition is in the ACC position. For your safety, always depress
the brake pedal when starting your Kia Carnival whenever possible.
CAUTION
- Avoid pressing the ENGINE START/STOP button for longer than 10 seconds unless the stop lamp fuse is confirmed to
be blown.
- Ensure the smart key is with you or located inside the Kia Carnival.
- Verify that the parking brake is firmly engaged.
- Shift the transmission into P (Park) and depress the brake pedal fully.
- Press the ENGINE START/STOP button.
- Begin driving at moderate speeds immediately; extensive stationary warm-up is unnecessary. Avoid rapid
acceleration or heavy braking during the initial warm-up period to protect your Kia Carnival
engine components.
CAUTION
To prevent potential mechanical damage, avoid turning off the engine immediately after it has been subjected to heavy
loads (such as climbing steep hills or high-speed towing). Allow the Kia Carnival engine to idle for
a short period to stabilize internal temperatures before shutdown.
