The rear light unit is a single unit, which includes: a brake light/side light, a turn signal, an additional side light, a reversing light and a fog light.

The block contains five lamps with bayonet mounts. (six lamps in US-supplied vehicles for which a side marker lamp is added). The lamp sockets are inserted into the corresponding holes in the housing in the light unit and are fixed when turned. Each socket is connected by wires to a connector, which is located on the rear of the rear light unit housing.

The rear light unit is built into a recess in the car body. The rear light unit is attached to the car body with two studs along the outer edge. From the inside, the light unit is attached with two screws, which are located near the opening of the trunk door.

Brake light and rear side light

The upper lamp is both a stop light and a marker lamp, which uses a 21 / 5W lamp with a bayonet cap. A 21-watt lamp is used in the brake light, and a 5 - watt lamp is used in the parking light.

The brake light is switched on when the ignition switch is in position II and the limit switch is closed when the brake pedal is pressed. The high brake light is also switched on when the brake pedal is pressed.

The brake light can be activated by the anti-lock brake system when the hill descent control (HDC) function is active. The signal from the ABS closes the contacts of a relay, through which electricity is supplied to the brake lights of the rear lights, as well as to the high-mounted brake light. For more information, refer to Anti-Lock Control - Traction Control (206-09A)

Turn signal lamp

The turn signal, which uses a 21W bayonet-type bulb, is located below the brake/parking light.

The direction indicators are activated by the left multifunction stalk or the hazard warning switch. The multifunction stalk only operates when the ignition switch is in position II (ignition on), the hazard warning switch operates in any circuit state. The direction indicators operate with an on/off cycle of 0.38 seconds.

When a bulb burns out, the working turn signal bulbs on the same side of the vehicle flash at the same rate. However, the corresponding turn signal indicator warns the driver of the burnt out bulb by flashing at twice the rate.

Clearance light

The clearance light, which uses a 21W/5W bayonet-type bulb, is located below the turn signal. Only the clearance light uses a 5W bulb.

The side lights are switched on by the light switch. The side lights can operate regardless of the ignition switch position. The side lights will also be switched on if the light switch is in the AUTO position and the central switching unit receives a signal from the rain/light sensor to switch on the outside lights.

Reversing light

The reversing light, which uses a 21W bayonet-type bulb, is located below the side light.

The reversing light is switched on when the ignition switch is in position II, provided that the CJB unit has received a signal via the CAN bus that reverse gear is engaged. Both manual and automatic transmissions have a reverse sensor that detects whether reverse gear is engaged.

Rear fog light

The rear fog light, which uses a 21W bayonet-type bulb, is located at the very bottom of the tail light cluster.

The rear fog lights are controlled by the light switch. If the ignition key is in position II and the light switch is set to the side lights or headlights position, the front fog lights are switched on by pressing the (if installed) you need to pull the switch to the second position. If the front fog lights are not installed, then it is enough to pull the light switch to the first position. When the rear fog lights are turned on, a warning indicator on the instrument panel comes on.
