ACC with LSF monitors if a vehicle ahead of you enters the ACC with LSF range. If a
vehicle is detected doing so, the ACC with LSF system maintains or decelerates your
vehicle’s set speed in order to keep the ve hicle’s set following-interval from the
vehicle ahead.

uuWhen Driving uVehicle Stability Assist ® (VSA ®), aka Electronic Stability Control (ESC), System
Driving
This button is on the driver side control panel.
To partially disable VSA ® functionality/
features, press and hold it until you hear a
beep.
Your vehicle will have normal braking and
cornering ability, but tra ction control function
will be less effective.
To restore VSA ® functionality/features, press
the (VSA ® OFF) button until you hear a
beep.
VSA ® is turned on every time you start the
engine, even if you turned it off the last time
you drove the vehicle.
■VSA ® On and Off1 Vehicle Stability Assist ® (VSA ®), aka Electronic Stability Control
(ESC), System
In certain unusual conditions when your vehicle gets
stuck in shallow mud or fr esh snow, it may be easier
to free it with the VSA ® temporarily switched off.
When the button is pressed, the traction control
function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the VSA ® off if
you are not able to free it when the VSA ® is on.
Immediately after freeing your vehicle, be sure to
switch VSA ® on again. We do not recommend driving
your vehicle with the VSA ® system switched off.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after starting the engine or
while driving. This is normal.

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to maintain
correct tire pressure, even if un der-inflation has not reached the
level to trigger illumina tion of the TPMS low ti re pressure telltale.
Your vehicle has also been eq uipped with a TPMS malfunction
indicator to indicate when the sy stem is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the system detects a malfunction, the
telltale will flash fo r approximately one minute and then remain
continuously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.
