dealer and have it repaired as soon
as possible...

Other information:
The vehicle identifies the number of
the current driver’s RKE transmitter
(1–8). See Remote Keyless Entry
(RKE) System Operation. If the
RKE transmitter is 1 or 2, and Seat
Entry Memory is programmed on in
vehicle personalization, the
positions saved to the same
memory button number 1 or 2 are
automatically recalled when the
ignition is turned on, or turned from off to ACC/ACCESSORY...
If the cruise control system is
already activated:
Press and hold +RES on the
steering wheel until the vehicle
accelerates to the desired
speed, then release it.
To increase the speed in small
increments, briefly press +RES.
For each press, the vehicle goes
about 1 km/h (1 mph) faster...
