Kia Picanto JA: Ignition System / Ignition Coil
Description and operation
An
ignition coil is an induction coil in an engine's ignition system which
transforms the battery's low voltage to the high voltage needed to
create an electric spark in the spark plugs to ignite the fuel. Coils
have an internal resistor while others rely on a resistor wire or an
external resistor to limit the current flowing into the coil from the
battery 12 V supply.

Repair procedures
| 1. | Turn ignition switch OFF and disconnect the negative (-) battery terminal. |
| 2. | Remove the air cleaner.
(Refer to Engine Mechanical System - "Air Cleaner")
|
| 3. | Disconnect the ignition coil connector (A). |
| 4. | Remove the ignition coil (B) after loosening the mounting bolts.
Ignition coil mounting bolt:
9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 Ib·ft) |
 Remove the ignition coil connector by pulling out the lock pin (A) and pushing the clip (B). |
 |
| 1. | Install in the reverse order of removal. |

Description
Ignition timing is controlled by the electronic control ignition timing system.
The
standard reference ignition timing data for the engine operating
conditions are pre-programmed in the memory of the ECM (Engine Control

Tire traction
Tire traction can be reduced if you drive
on worn tires, tires that are improperly
inflated or on slippery road surfaces.
Tires should be replaced when tread
wear indicators appear. Slow down
whenever there is rain, snow or ice on
the road to reduce the possibility of
losing control of the vehicle...
This section will guide you in the proper
loading of your vehicle, to keep your
loaded vehicle weight within its design
rating capability. Properly loading your
vehicle will provide maximum return of
the vehicle design performance. Before
loading your vehicle, familiarize yourself
with the following terms for determining
your vehicle's weight ratings,
from the vehicle's specifications and
the certification label:
Base curb weight
This is the weight of the vehicle including
