BEFORE YOU DRIVE
OCCUPANT SAFETY
rearwards. The height of a car seat must
only be adjusted by your authorised
McLaren Retailer.
WARNING: If the child restraint system
has not been fitted correctly, the child
cannot be restrained in an accident or
sudden braking and could be injured.
When fitting a child restraint system,
observe the manufacturer's instructions
on the correct use of the child restraint.
KISI Child Restraint Function
Your McLaren is fitted with a KISI system
which is an automatic locking seat belt on the
passenger's side designed to temporarily lock
the seat belt to securely hold the child
restraint in the passenger's seat.
1. Extend the passenger's seat belt fully.
The KISI system only engages when the
seat belt is fully extended.
NOTE: If the vehicle is parked on a hill the
inertia lock may stop the seat belt
extending. If this occurs, release the seat
belt slightly and continue to extend the
seat belt carefully to avoid the
engagement of the inertia lock.

2. Pass the seat belt through the child
restraint as described by the child
restraint manufacturer and engage the
belt latch in the buckle.
3. Adjust the belt so that the lower section
is tight against the restraint and allow
the upper section to retract. The KISI
system will click as the belt retracts.
4. When the seat belt has retracted as far as
possible, pull on the upper section to
check that the seat belt has locked.
NOTE: The KISI system will disengage
when the seat belt has fully retracted
and can then be worn as a normal seat
belt. Once the KISI system has unlocked,
it will be necessary to fully extend the
seat belt to engage the KISI system the
next time a child restraint is used.
