Engine Coolant
Temperature Warning
Light
The engine coolant temperature
warning light comes on briefly when
the engine is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally, the
indicator light then goes off.
If the light comes on and stays on
while driving, the vehicle may have
a problem with the cooling system.
Stop the vehicle and turn off the
engine to avoid damage to the
engine. A warning chime sounds
when this light is on.
See Engine Overheating on
page 10 21 for more information.

Tyre Pressure Light

For vehicles with the Tyre Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tyre pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of
the tyres are significantly
underinflated.
A Driver Information Centre (DIC)
tyre pressure message may also
display. See Tyre Messages on
page 5 45. Stop as soon as
possible, and inflate the tyres to the
pressure value shown on the Tyre
and Loading Information label. See
Tyre Pressure on page 10 61.
Instruments and Controls
When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the
problem is not corrected, the light
will come on at every ignition cycle.
See Tyre Pressure Monitor
Operation on page 10 64.

Engine Oil Pressure Light

Notice: Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine
oil low can also damage the
engine. The repairs would not be
covered by the vehicle warranty.
Check the oil level as soon as
possible. Add oil if required, but
if the oil level is within the
operating range and the oil
pressure is still low, have the
vehicle serviced. Always follow
the maintenance schedule for
changing engine oil.
