STARTING & DRIVING

Rear Driver Assistance System

System Overview

The rear driver assist system may not provide

adequate warning of very fast approaching

vehicles or operate correctly on tight curves

of radius.

The rear driver assistance sensors may

misidentify some surroundings, such as

roadside buildings or guardrails and provide

a false alarm.

The rear driver assist system will not operate

correctly whilst towing a trailer or caravan.

The effective recognition capabilities of the

rear sensors can be limited by objects such

as roadside buildings, guardrails, changes in

pitch angle of the car due to heavy loading,

road conditions such as bends or bumps or

weather conditions such as snow and ice etc.

Any of the above may trigger a false alarm.

The correct operation of the rear sensors will

be compromised if they are misaligned due to

accident damage. This may cause the system

to automatically shutdown.

To ensure that the radar sensors work

correctly, the rear bumper should be kept

free of snow and ice and must not be covered.

The rear driver assistance function is only an

aide, it is NOT a substitute for the attention

of the driver. The driver must always remain

in control, observe the surroundings and drive

safely.

Use of non recommended materials or

paint on rear bumper repairs may have a

detrimental effect on the operation of the

rear sensors. Please only use recommended

materials.

227

STARTING & DRIVING

The rear driver assistance system includes blind spot

detection (BSD), lane change assist (LCA), rear cross

trafﬁc alert (RCTA) and door open warning (DOW)

functions.

Note: The radar requires calibration on new vehicles

or for vehicles of where rear detecting radar

a

sensor has been replaced. The rear detection radar

sensors possess an automatic calibration function to

compensate for installation error within a certain

range. When the vehicle is running, the radar will

automatically enter the calibration state. During the

calibration process, the system will provide limited

functions, and the alarm may be inaccurate. Upon

completion of the calibration, the system will resume

all functions.

The rear driver assistance modules are mounted at the

rear of the vehicle on each side, they can assist in detecting

vehicles behind or to the side of your vehicle.

The warning lamps to support this system are located

within the LH and RH door quarter light trims, they will

illuminate or ﬂash to warn of an approaching object or car

to assist you in manoeuvring the car safely.

Switching the System Functions On/Off

The rear driver assist system function switches can be

accessed via the infotainment screen.

Select: 'Vehicle Settings', 'Driving Assist' and 'Rear Driving

Assist' (you may have to scroll left or right to access this

option). Select ON/OFF to activate/deactivate the system.

A warning message to alert you of your choice will be

displayed in the message centre in the instrument pack.

If the 'Rear Driving Assist' is ON, the sub system menu

will become 'live' and you can select the ON/OFF option

228

STARTING & DRIVING

for each of the sub systems. If the 'Rear Driving Assist' is

switched OFF, none of the sub systems will be selectable

and the entire system will be in an OFF state.

System Functions

Blind Spot Detection (BSD)

When the vehicle is driving forward, the system will

monitor for motor vehicles located in the blind zones of

the left and right exterior mirrors. When the conditions

for activating the blind spot detection function are met, the

corresponding warning lamps will illuminate. Subsequent

operation of the relevant indicator will cause the warning

lamp to ﬂash to remind the driver of an approaching

vehicle.

When the vehicle is restarted, the system will keep the

previously stored switch settings.

of the vehicle, the monitored areas are 2m ahead , 7m

behind the rear of the vehicle, and 4.7m from the side

of the vehicle.

Note: The warning lamps will not illuminate whilst

you are overtaking another vehicle and your speed is

greater than that of the vehicle you are passing, even

though it is in the blind zone.

The conditions for activating the blind spot detection

function include:

1

Rear driver assistance system is in the ON state and

no faults are present in the system.

2

Blind spot detection (BSD) function is enabled.

The vehicle speed is above 20mph (30km/h).

There are motor vehicles in the blind zone of the

vehicle. The system monitors both the left and right

230

STARTING & DRIVING

Lane Change Assist (LCA)

The conditions for activating the lane change assist function

include:

When the vehicle is driving forward, the system will

monitor for motor vehicles approaching rapidly in the

adjacent lanes. When the indicators are activated, and the

conditions for activating the lane change assist function

are met, the system will ﬂash the respective warning lamp

to warn the driver of an approaching vehicle. This aims to

help avoid collisions when changing lanes.

The approaching vehicle enters the detection area of

the LCA, the monitored areas are 7m - 70m behind

your vehicle and 4.7 m to the side of your vehicle.

The approaching vehicle is likely to have a collision with

your vehicle within 3.5 seconds.

231

STARTING & DRIVING

Rear Cross Trafﬁc Alert (RCTA)

The conditions for activating the rear cross trafﬁc alert

function include:

When the vehicle is reversing, the system will monitor

vehicles approaching from the left and right rear. When

the conditions for activating RCTA function are met,

the warning lamps on the corresponding side will

illuminate, simultaneously a warning triangle icon for the

corresponding side will be displayed in the infotainment

screen to alert the driver to the situation.

Door Open Warning (DOW)

Whilst the vehicle is stationary, the Door Open Warning

system monitors the surrounding area for approaching

vehicles, motorcycles and bicycles.

If the approaching object meets the conditions

programmed into the system the corresponding warning

light will illuminate to warn the occupant of the

approaching object and assist in avoiding any collisions

when the door is opened.
