Vehicle Stability Assist (VSA ), aka Electronic Stability Control (ESC), System
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.

VSA and Tire Sizes
Driving with varying tire or wheel
sizes may cause the VSA to
malfunction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page 574 ).
If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.
Hill Start Assist
On models with SH-AWD
Your vehicle is equipped with a hill
start assist feature to help prevent
the vehicle from rolling on inclines
as you move your foot from the
brake pedal to the accelerator.
To activate hill start assist, you must
come to a complete stop and make
sure the shift lever is either in D or S
when facing uphill, or reverse when
facing downhill. This feature begins
working a few seconds after you are
in the correct gear position. Release
the brake pedal. The brakes remain
engaged briefly to keep the vehicle
from rolling forward or backward.
Gently apply the accelerator pedal as
in normal driving. Hill start assist will
release brake pressure gradually as
you accelerate.
