such as trying to take a
corner too f ast or making a sudden
lane change. Always drive at a safe
speed f or the road and weather
conditions.
Always steer moderately
when you are braking hard. Severe
or sharp steering wheel movement
can still cause your vehicle to veer
into oncoming traffic or off the road.
If the ABS indicator and the brake
system indicator come on together,
and the parking brake is f ully
released, the EBD system may also
be shut down.
Test your brakes as instructed on
page . If the brakes f eel normal,
drive slowly and have your vehicle
repaired by your dealer as soon as
possible. Avoid sudden hard braking
which could cause the rear wheels to
lock up and possibly lead to a loss of
control.
The VSA indicator will come on

The vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surf aces. It does this
by regulating the engine’s output and
by selectively applying the brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some noise f rom the VSA
hydraulic system. You will also see
the VSA activation indicator blink.
The VSA system cannot enhance the
vehicle’s driving stability in all
situations and does not control your
vehicle’s entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.When VSA activates, you will see the
VSA activation indicator blink.
If this indicator comes on while
driving, pull to the side of the road
when it is saf e, and turn of f the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on or comes
back on while driving, have the VSA
system inspected by your dealer.
If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehicle as
soon as possible.
You will also see a ‘‘CHECK VSA
SYSTEM’’ message on the multi-
inf ormation display if there is a
problem with the VSA system.
If the low tire pressure/TPMS
indicator comes on, or the multi-
inf ormation display shows a
‘‘CHECK TPMS SYSTEM’’ message,
the VSA system automatically turns
on even when the VSA system is
turned of f by pressing the VSA OFF
switch (see page ). If this
happens, you cannot turn the VSA
system of f 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.

This switch is under the driver’s side
vent. To turn the VSA system on and
of f , press and hold it until you hear a
beep.
When VSA is off, the VSA activation
indicator comes on as a reminder.
With the VSA of f , the trailer stability
assist f unction is also turned of f (see
page ).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 f resh snow, it may be easier
to free it with the VSA temporarily
switched of f . When the VSA system
is of f , the traction control system is
alsooff.Youshouldonlyattemptto
f ree your vehicle with the VSA of f if
you are not able to f ree it when the
VSA is on.
Immediately af ter f reeing 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.
Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page ).
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.

Under these conditions, trailer
stability assist begins to stabilize the
vehicle/trailer combination by
reducing the vehicle speed. The
control unit sends signals to
selectively apply the brakes and
regulate the engine output. The
brake lights of your vehicle will be
turned on automatically by the
system even if you do not keep the
pressure on the brake pedal.
Your vehicle is equipped with trailer
stability assist f unction. This
f unction works on the same sensors
as the vehicle stability assist (VSA)
system. This f unction helps to
stabilize the vehicle/trailer
combination when the trailer
severely sways or oscillates. For
more inf ormation of the VSA system,
see page .
When the brakes are applied, the
trailer’s brake lights come on along
with the vehicle brake lights.
When the trailer stability assist
activates, you will see the VSA
activation indicator blink. There may
also be some noise f rom the VSA
hydraulic system.Trailer stability assist cannot prevent
a loss of control. Always reduce the
vehicle speed and steer f irmly. Do
not brake suddenly or make quick
steering motion. It could cause the
trailertojackknifeorturnoverand
the system becomes inef f ective.
Trailer stability assist cannot prevent
swaying that can occur in crosswinds
and in normal and emergency
driving maneuvers. It helps only to
stabilize the vehicle/trailer
combination in these conditions,
af ter the oscillation becomes severe.
If the function detects the vehicle/
trailer instability, it checks if the
swaying is caused by the trailer, and
if the trailer swaying or oscillation is
increasing.
The vehicle/trailer combination is
more af f ected by crosswinds,
buf f eting, and improper tongue load.
These conditions can make the
trailer unstable, and cause it to sway. Always obey the recommended
speed limits f or towing a trailer, see
page .
Trailer stability assist will also be
inef f ective while driving at high
speed or towing a trailer with a high
center of gravity.
