Starting and Driving

Exhaust Temperature Monitoring

The vehicle continuously monitors exhaust
temperatures to protect the catalytic
converters from damage caused by
overheating.
If excessive exhaust temperatures are
measured a warning will be displayed on
the Driver Display. The vehicle speed
should be reduced as soon as this message
is observed. Refrain from maneuvers
involving high engine speed and high
engine load (full throttle) to allow the
exhaust to cool. The message will remain
until the temperature has reduced.
If the exhaust temperature remains at an
excessive level a second warning is
displayed and limphome mode is activated.
The engine performance will remain
limited until the vehicle is restarted.
NOTE: Catalytic converter over
temperature warnings are not likely
to be observed during normal
driving and are the result of
extreme operating conditions. For
example, high exhaust
temperatures can be caused by
extended track driving, maintaining
high engine speed for long
durations, and sudden and repeated
changes in throttle demand.
NOTE: High exhaust temperatures
can cause damage to catalytic
converters and should be avoided by
practicing careful driving.
If the warnings persist contact your
McLaren retailer.

Parking Sensors

The parking sensors alert the driver to any
obstructions while maneuvring at low
speeds. The system comprises four
ultrasonic sensors in the front bumper, four
ultrasonic sensors in the rear bumper and
two sounders. Each sounder has a different
pitch to indicate whether the obstruction is
at the front or the rear of the vehicle.
The front parking sensors are
automatically switched on when the
engine is running and drive is selected. The
rear parking sensors are switched on when
reverse gear is selected. The light around
the parking sensors button will illuminate
amber to indicate that parking sensors are
active.
