Heated Seats
Some seats have heaters in the backrests
and cushions. The heaters have three
heat settings and each seat has its own
control.
The front seat buttons are located at the
top of the centre console.
With the engine running, pressing a
heater button will select the highest heat
setting, as indicated by three illuminated
red lights.
A second press selects the mid setting
(two red lights) and a third press selects
the lowest heat setting (one red light).
A fourth press turns the seat heater off;
all indicator lights off. The rear seat heater buttons are located
below the rear air vents.
Note:
The heater will automatically
switch off if the engine is turned off or if a
fault is detected.
A heater will maintain a preset
temperature while it is switched on.
Storage of the vehicle in a heated garage,
body heat or warm ambient temperatures
may prevent operation of the seat heater.
Heated Steering Wheel
A heater is incorporated in the steering
wheel rim and operates in conjunction
with the driver’s seat heater. The steering
wheel heater is switched on in any of the
three driver seat heater positions.

Changing the set speed
There are three ways to change the set
speed:
1. Accelerate or brake to the required speed and press the ‘SET +’ button.
2. Increase or decrease the speed by pressing and holding either the
‘SET +’ or ‘–’ button until the required
set speed is shown on the message
centre. The vehicle speed will
gradually change to the selected
speed.
3. Increase or decrease the speed in steps of 1 mph (2 km/h) by briefly
pressing the ‘SET +’ or ‘–’ button.
ACC operates between approximately
20 mph and 110 mph (34 km/h and
180 km/h) dependent on the country
specification.
Set speeds outside this range will not be
captured.
The ACC may apply the brakes to slow
down the vehicle to the new set speed.
The new set speed will be displayed on
the message centre for four seconds after
it has been changed. Changing the gap
The gap from the vehicle ahead can be
decreased or increased by pressing the
gap setting rocker switch on the steering
wheel. Four gaps are available and the
selected gap setting will be displayed on
the message centre when the rocker
switch is pressed. After the ignition is
switched ON the default gap will be
automatically selected ready for ACC
operation.
Note:
It is the driver’s responsibility to
select a gap appropriate to the driving
conditions, and in accordance with
national driving regulations.
ACC automatic switch off
Adaptive cruise control will disengage,
but not clear the memory when:
• The CANCEL button is pressed.
• The brake pedal is pressed.
• The vehicle speed falls below 18 mph (30 km/h).
• Neutral, Park or Reverse gear positions are selected.
• The parkbrake is applied.
• DSC is activated. Adaptive cruise control will disengage,
and clear the memory when:
• The ignition switch is set to
position ‘0’.
• Maximum vehicle speed is reached.
• A fault occurs in the ACC system.
Resuming the set speed/follow mode
By pressing the RESUME button after ACC
has been cancelled, for example, after
braking, the ACC will become active
again provided that the set speed
memory has not been erased. The set
speed will be displayed for four seconds
and the original set speed will be
resumed, unless a vehicle ahead causes
the follow mode to become active.
Caution: ‘RESUME’ should only be
used if the driver is aware of the set
speed and intends to return to it.
