Exhaust Temperature Monitoring; Parking Sensors - McLaren Ultimate Series Owner's Handbook Manual

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
manoeuvres 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 high speed 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 manoeuvring 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.
