available in English on U.S. models,
andinbothEnglishandFrenchon
Canadian models. To change the
language, see page . HFL recognizes simple voice
commands, such as phone numbers
and names. It uses these commands
to automatically dial, receive, and
store numbers. For more
inf ormation on voice control, see
UsingVoiceControlonpage .
Here are the main features of the
HFL. Instructions f or using the HFL

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.

The weight that the tongue of a f ully
loaded trailer puts on the hitch
shouldbe5to10percentof thetotal
trailer weight f or boat trailers, and 8
to 15 percent of total trailer weight
f or all other trailers. (See page
f or limits f or your towing
situation). Too much tongue load
reduces front-tire traction and
steering control. Too little tongue
load can make the trailer unstable and cause it to sway.
The maximum
allowable weight of the vehicle, all
occupants, all accessories, all cargo,
and the tongue load must not exceed
2,888 lbs (1,310 kg) on the f ront axle,
and 3,175 lbs (1,440 kg) on the rear
axle. The maximum
allowable weight of the vehicle, all
occupants, all accessories, all cargo
and the tongue load is 5,952 lbs
(2,700 kg).
The maximum allowable weight of
the trailer and everything in or on it
depends on the number of occupants
inyourvehicleandthetypeof trailer
being towed (see page ).
Towing a trailer that is too heavy can
seriously af f ect your vehicle’s
handling and perf ormance. It can
also damage the engine and
drivetrain. The maximum
allowable weight of the f ully loaded
vehicle and trailer is 10,053 lbs
(4,560 kg) with the proper hitch. The
GCWR must be reduced 2 percent
f or every 1,000 f eet (305 meters) of
elevation.

If youturnoff theVSA,thetrailer
stability assist f unction also shuts of f .
Press and hold the VSA of f switch
until you hear a beep (see page ).
The VSA activation indicator comes

The control unit monitors the VSA
circuitry and the braking system. If
there is a problem with the brake
lighting system, the trailer stability
assist f unction shuts down and the
‘‘CHECK TRAILER STABILITY
ASSIST’’ message appears on the
multi-inf ormation display.
If you see this message, have your
vehicle checked at your dealer as
soon as possible. In this case, your vehicle still has the
VSA traction and stability
enhancement, but it will not have the
trailer stability assist f unction.
If there is a problem with the VSA
system, the system and Trailer
Stability Assist shuts of f . The VSA
system and VSA activation indicators
also come on (see page ).
The ABS indicator and the brake
system indicator may also come on

The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices and dif f erences in
road characteristics and climate.The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades.
Quality grades can be f ound where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:
