Limphome mode
Limphome mode activates automatically when
vehicle systems detect a fault which may cause
further damage unless vehicle or system
performance is restricted. Care should be taken
while driving in this mode. Contact your McLaren
retailer immediately.
Economical driving
Improved fuel economy can be achieved by
following this advice:
• Accelerate smoothly and gently from a
standing start.
•
When in manual mode, avoid high engine
rpm by changing to a higher gear as soon
as possible.
The gear shift indicator (GSI) will
illuminate when an upshift would
maintain optimum economy.
NOTE: Not available in all markets,
consult your McLaren retailer.
•
Avoid labouring or over-revving the engine.
• Switch off the air conditioning when it is
not needed.
• Avoid journeys where frequent stop/start
driving is involved.
•
Ensure that your driving style suits the
prevailing road and traffic conditions; allow
time for smooth, progressive acceleration
and braking. 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 track driving, maintaining
high engine speed for long durations,
and sudden and repeated changes in
throttle demand.
