Driving
Vehicle Stability Assist ® (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine output and selectively applying the brakes.
When VSA® activates, you may notice that the
engine does not respond to the accelerator.
You may also notice some noise from the
hydraulic system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability Assist ® (VSA ®), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there may be a problem with the
system. While this may not interfere with normal
driving, have your vehi cle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stab ility Control (ESC). The
system also includes a traction control function.

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.

Agile Handling Assist
Lightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehi cle’s stability and performance during
cornering.1 Agile Handling Assist
The agile handling assist ca nnot enhance stability in
all driving situations. You still need to drive and
corner at speeds appropriate for the conditions and
always leave a sufficient margin of safety.
When the VSA ® system indicator comes on and stays

activate.
You may hear a sound coming from the engine
compartment while the agile handling assist is
activated. This is normal.

is reset, change the engine oil every year.
# : See information on maintenance and emissions warranty.
*2: If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
*3: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).

*4: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission
temperature. This requires transmission fluid changes more frequently than recommended by the
Maintenance Minder. If you regularly drive your vehicle under these conditions, have the transmission
fluid changed at 30,000 miles (48,000 km).
*5: If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under -20°F, -29°C), replace every 60,000 miles/100,000 km.
*6: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of
mechanical (Shear) stress to fluid. This requires differential fluid changes more frequently than
recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

Maintenance
Tire and Wheel Replacement
Replace your tires with radials of the sa me size, load range, speed rating, and
maximum cold tire pressure ra ting (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause ce rtain vehicle systems such as the ABS and
Vehicle Stability Assist ® (VSA®) system to work incorrectly.
It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
If you replace a wheel, only use TPMS sp ecified wheels approved for your vehicle.
Make sure that the wheel’s specifications match thos e of the original wheels.1Tire and Wheel Replacement
3WARNING
Installing improper tires on your vehicle can
affect handling and stability. This can cause
a crash in which you can be seriously hurt or
killed.
Always use the size and type of tires
recommended in this owner’s manual.
