Vehicle Stability Assist (VSA
You will also see a ''CHECK VSA
SYSTEM'' message on the multi-
information display if there is a
problem with the VSA system.
If the low tire pressure/TPMS
indicator comes on, or the multi-
information display shows a ''CHECK
TPMS SYSTEM'' message, the VSA
system automatically turns on even
when the VSA system is turned off
by pressing the VSA OFF switch
(see page 360). If this happens, you
cannot turn the VSA system off by
pressing the VSA OFF switch again.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.

VSA Off Switch
This switch is under the driver's side
vent. To turn the VSA system on and
off, press and hold it 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.
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or fresh snow, it may be easier
to free it with the VSA temporarily
switched off. When the VSA system
is off, the traction control system is
also off. 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 the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.
