Tyre Pressure Monitoring System (TPMS)
On cars so equipped, a sensor incorporated into each of the tyre valves, monitors the air pressure inside
the tyre, and supplies an onboard control module with this data by radio transmission. As soon as the car has
been driven a short distance, tyre pressure readings will be displayed against the corresponding wheels on
the vehicle silhouette in the instrument cluster right hand screen. If any pressure should fall below 75% of the
recommended value, an alert message is sent to the instrument panel, causing the tyre pressure tell tale
to light up amber, and the corresponding pressure on the silhouette to flash.
If this warning should occur, stop the car as soon as it is safe so to do, and examine the affected tyre. If
there is no visible damage and a tyre pump is available, correct the pressure to that stated in the Technical
Data section of this handbook, and proceed with caution to a tyre dealer for professional inspection and advice.
Note that the tell tale will automatically be extinguished when the correct pressure is restored. If the tyre is
punctured, or no inflation equipment is available, consider using the emergency tyre inflator aerosol (see page
128), but observe the associated WARNINGS and be aware that the TPMS sensor in the tyre will be disabled
by the sealing fluid, and must subsequently be renewed.
The TPMS incorporates self-malfunction recognition, and if a fault is detected, the low tyre pressure tell
tale will flash for one minute and then remain constantly lit, this sequence being repeated for subsequent ignition
cycles; the system may not be able to detect or signal low tyre pressure . See your dealer without delay.
Be sure to advise any tyre fitters or service technicians that TPMS is fitted, and that any replacement tyre
valves include the correct pressure sensors. If a fault is indicated after wheel or tyre replacement, it is likely
that a sensor has been incorrectly fitted or damaged. If a tyre valve is renewed, or is moved to a different wheel
position, the TPMS will automatically identify the new configuration.
Note that the pressure sensors are powered by integral batteries, with an average service life of 10 years.
It is recommended to renew all pressure sensors at this time interval.
Door/Tailgate Open Display
The instrument cluster right hand screen includes a plan view silhouette of the car, which will graphically
show when either door is open, or indicate an open tailgate by flashing the corresponding area. This situation
will endure until the panel is fully latched.
Lighting Switches
Lighting functions are controlled by a vertical row of three push button switches mounted in the fascia
outboard of the steering column. Each switch is pressed once to switch on, and pressed a second time to
switch off. Each switch button incorporates a function symbol which is backlit red with the sidelamps and igni-
tion switched on, and which lights up brightly when the circuit is active.
Sidelamp Switch
The topmost outboard switch functions with or without the ignition, and switches on the sidelamps and
some switch illumination. To help locate the switch in the dark, when the ignition is on, the button symbol will
be backlit red, changing to brightly lit green when the circuit is activated.
Note that the headlamps must be off before the sidelamps can be switched off.
Headlamp Switch
The second switch down functions with or without ignition, and switches on the headlamps together with
the sidelamps and some switch illumination. The switch button symbol is backlit red with the sidelamps on,
and lights up green to indicate when the circuit is active. The steering column lever switch (see later) is used
to select main or dip beam.
A second momentary press will switch off the headlamps, but leave on the sidelamps. To switch off both
the side and headlamps, hold the switch pressed for more than one second.
Homesafe
The Homesafe feature keeps the headlamps lit for a 30 second period after locking/arming the alarm, in
order to light the departure route. To activate Homesafe;
- leave the headlamps switched on;
- withdraw the ignition key;
- use the transmitter to lock/arm the alarm.
The master lighting switch will flash during the 30 second period to indicate that Homesafe is operating.
