11.4.2.2 Interior Lighting Description and
Operation

Door Controlled Lamp

Door controlled lamps are in the dome lamps. The switch is at
the left. When the switch is pressed, the door opens, the door
controlled lamps will be on. Close the door, the door controlled
lamps will be off after a few seconds delay. When the switch is
lifted, with the door open, the door controlled lamps will not be
on. Reading lamps are at both sides of the dome lamp. The
switch is located at the right side. Press the switch, both sides
lamps will be on at the same time. Release the switch, both
lamps will be off at the same time.

Rear Compartment Lamp

For sedan vehicles, the rear compartment lamp is located
beneath the rear compartment lid. For hatchback vehicles, the
rear compartment lamp is located on the left side of the wheel
cover panel. As long as the rear compartment (hatchback) is
open, the lamp will be on.

11.4.2.3 Comfortable Lighting Control

Following Lighting

If the headlamp switch is turned from "OFF" to "ON" (park lamp,
headlamp or auto headlamp) and then to "OFF" again within
10 min the ignition key is pulled out, the following lighting
function will be activated. The headlamps will be lit after 30 s
delay. When the following lighting function is activated, if one
door is opened="Headlamps will be lit after 180 s delay. The
180 s delay is the timing for any door (including rear
compartment)opening. After all doors are closed, it will re-time
30 s.

Automatic Headlamp

When the ignition switch is at "ON", headlamp switch is at
"AUTO", the park lamp relay and headlamp relay will
automatically pull-in or disconnect (requires ambient and sun
light sensor signal input) according to the surrounding
environment brightness.

Lamp Detection

During turning, if one of the turn signal lamps is (21W)
damaged, the other turn signal lamp will flash at about double
normal frequency.

Fade Lighting Features

–

BCM controls dome lamp fade in light in about 0.7s, fade
out in about 1.7s.

–

When unlocking, the dome lamp will fade in light, if there is
no door open action, 15 s after the dome lamp will fade out.

–

When lock (locking device operated), the dome lamp will
fade out in about 1.7s.

–

With all doors closed and the ignition switch is turned off,
dome lamp will fade out in 15 s; doors all shut, the ignition
switch is open, dome lamp fade out immediately
extinguished.

–

With all doors closed and the ignition switch is turned on,
dome lamp will immediately extinguish.

–

Opening any door, dome lamp will fade in light and keep lit,
until the door is closed then fade out in 1.7s, or turned off
because of energy saving feature (with the ignition switch
is at OFF, the energy saving feature will be activated in 20
min).

Emergency Braking Warning Lamp

If the vehicle speed (BCM receives signal through CAN Bus)
rapidly decreases due to emergency braking, all turn signal
lamps will be activated and flashing; if the vehicle speed stops
decrease, the alarm flash will be deactivated. (Speed decrease
more than 0.55g is regarded as an emergency braking). This
feature is enabled when all following conditions are met:

1. The current speed is greater than or equal to 45 km/h (if

less than 45 km/h, even if an emergency brake is detected,
HOD will not be triggered).

2. The brake pedal is pressed and held.

3. Hazard warning lamp (Hazard) have not been manually

switched on by driver.

4. Emergency braking has been detected, namely: in 1,000ms

sampling time, deceleration value is greater than or equal
to the following pre-defined HOD activation deceleration
threshold.

5. the pre-defined HOD activation deceleration threshold is

stored in the EEPROM vehicle configuration part. It is the
factory default value. If a user needs to change, it can be
re-configured through scan tool commands.

When the following conditions are met, this feature will be
deactivated:

1. After emergency braking warning lamp (HOD) is triggered,

the running time is no less than 1,000 ms (either manually
or automatically turn off).

2. Driver manually switched off hazard warning lamp.

3. Brake pedal has been released.

4. The vehicle starts accelerating again, that is, in 2000ms

speed sampling time, the vehicle acceleration value is
greater than or equal to pre-defined stop HOD flashing
acceleration threshold.

5. The pre-defined stop HOD flashing acceleration threshold

value is also stored in the EEPROM vehicle configuration
part. It is selected as the factory default value. If a user
needs to change, it can be re-configured through scan tool
commands.

6. If the HOD is triggered and the vehicle is stopped, the HOD

continues to run until the vehicle acceleration is detected
again, and the acceleration value satisfies the above
conditions.

11.4.3 System Working Principle
11.4.3.1 System Working Principle

Headlamp Working Principle

When the headlamp switch is at "headlamp" position, the
working voltage is provided by terminal 8 to pull-in headlamp
relay and light up headlamps. Headlamp supply voltage is sent
to the headlamp adjustment switch and the left and right
headlamp adjustment motors. Moving up and down the switch
can change the adjustment adjustment motor signal voltage, to
achieve the headlamp height adjustment.

Note

Moving this button too frequently may cause motor
inoperative or damage.

When BCM (the center controller) detects the headlamp switch
terminal 12 voltage, it means the switch is at "AUTO"
(automatic transmission), at this time BCM will monitor the
ambient light sensors signal. If the ambient light is not strong,
BCM sends power from IP29 terminal 31 to drive the headlamp
relay, the headlamps will be automatically lit. When the ambient
light is increased, BCM will cut off the power supply output,
headlamps will be automatically off.

When the lighting switch is at high beam position, the working
voltage is from the switch terminal 7 to drive high beam relay,
at the same time the high beam power supply voltage is
transmitted to the instrument panel to light high beam indicator.

Note

High beam relay working voltage is from the headlamp
power supply circuit.

Park Lamp Working Principle

When the headlamp switch is at "headlamp" position, the
working voltage is sent from terminal 14 to drive the park lamp
relay and illuminate all park lamps, instrument lights, as well as
left and right license plate lamps; at the same time this voltage
is sent to the backlight adjustment switch, this switch can be
used to adjust the backlight brightness.

Note

The BCM connector IP29 terminal 16 can also be used
to drive park lamp relay, for example, when the vehicle
is unlocked with the remote control, BCM light park
lamps through this circuit.

Front Fog Lamp Working Principle

Front fog lamps relay coil drive power supply is from the park
lamp power supply circuit. When the front fog lamp switch is
turned on, the switch ground circuit will drive the front fog lamp
relay. The working voltage through the relay will light front fog
lamps. At the same time this voltage is sent to the instrument
panel front fog lamp indicator.

Note

Note that front fog lamps working voltage will be sent to
rear fog lamps at the same time.

Rear Fog Lamp Working Principle

When the rear fog lamp switch is turned on, the power supply
from the front fog lamps will drive the rear fog lamps relay and
light rear fog lamps, while the voltage is also sent to the
instrument panel front fog lamp indicator.

Note

Note: The sedan has a separate rear fog lamp assembly;
hatchback has only one rear fog lamp, located inside the
left tail assembly.

Turn Signal Working Principle

The multi-function lever controls light switch terminals 1 and 3
ground circuits. This ground signal is sent to BCM. BCM lights
the left and right turn signals through IP28 terminals No.4,13
respectively.

Note

When the hazard warning lamp button is pressed, BCM
will send output voltage to these two circuits at the same
time to light all turn signal lamps.

Brake Lamp Working Principle

The brake lamps are controlled by the brake lamp switch on
the brake pedal. When the brake pedal is pressed. the working
voltage is directly sent to the brake lamp bulb.

Note

Sedan high mounted brake lamp is located on the rear
parcel shelf inside the rear window. Hatchback high
mounted brake lamp is located at the top of the
hatchback.

Reverse Lamp Working Principle

Reverse lamps are controlled by the reverse lamp switch.
When the vehicle is at reversing, the working voltage is directly
sent to the brake lamp bulb.

Note

Hatchback has only one reverse lamp, located inside the
right tail lamp assembly.

Courtesy Lamp and Rear Compartment
(Hatchback) Lamp Working Principle

Courtesy lamp and rear compartment lamp (Hatchback) power
is from fuse IF19.

When the door is opened, the door lock will connect the door
courtesy lamp circuit to ground so that the door courtesy lamp
will be lit.

When the rear compartment (Hatchback) is opened, the rear
compartment (Hatchback) lock connects the rear compartment
lamp (Hatchback) ground circuit and light rear compartment
lamp (Hatchback).
