VSA
® OFF Button

P.205
The vehicle stability assist (VSA
®)
system helps stabilize the vehicle during
cornering, and helps maintain traction
while accelerating on loose or slippery
road surfaces.
VSA
® comes on automatically every time
you start the engine.
To turn VSA
® on or off, press and hold the
button until you hear a beep.
Cruise Control

P.201
Cruise control allows you to maintain a set
speed without keeping your foot on the
accelerator pedal. To use cruise control, press the CRUISE
button, then press DECEL/SET when the
vehicle speed is above 25 mph (40 km/h).Tire Pressure Monitoring
System ( TPMS)

P.206
TPMS monitors tire pressure. TPMS is turned on automatically every
time you start the engine.
Refueling
P.215
Fuel recommendation:
4-cylinder models

Premium unleaded gasoline with a pump octane
number 91 or higher recommended
6-cylinder models

Premium unleaded gasoline with a pump octane
number 91 or higher required
Fuel tank capacity: 18.5 US gal (70 L)

Unlock the driver's door. Press on the edge of the
fuel fill door to make it
pop up slightly. Turn the fuel fill cap
slowly to remove the cap. Place the cap in the
holder on the fuel fill
door. After refueling, screw the
cap back on until it clicks
at least once.

Towing a Trailer
Continued
Driving
Towing Load Limits
Your vehicle can tow a tralier if you carefully observe the load limits, use the
proper equipment, and follow the towing guidelines. Check the load limits before
driving.
Total trailer weight
Maximum allowable weight of the trailer,
cargo, and everything in or on it must not
exceed 1,000 lbs (450 kg). Towing loads in
excess of this can seriously affect vehicle
handling and performance and can damage
the engine and drivetrain. Tongue load
The weight of the tongue with a fully loaded
trailer on the hitch should be approximately
10% of the total trailer weight.
Excessive tongue load reduces front tire t
traction and steering control. Too little
tongue load can make the trailer unstable
and cause it to sway.
To achieve a proper tongue load, start by t
loading 60% of the load toward the front
of the trailer and 40% toward the rear.
Readjust the load as needed.
Towing Load Limits
Check if all loads are within limits at a public scale.
If a public scale is not available, add the estimated
weight of your cargo load to the weight of your
trailer (as quoted by the manufacturer), and the
tongue load.
Break-in Period
Avoid towing a trailer during your vehicle's first 600
miles (1,000 km).
WARNING
Exceeding any load limit or improperly
loading your vehicle and trailer can cause
a crash in which you can be seriously hurt
or killed.
Check the loading of your vehicle and
trailer carefully before starting to drive.

VSA
® (Vehicle Stability Assist), aka ESC (Electronic Stability Control), System
VSA
® (Vehicle Stability Assist), aka ESC (Electronic
Stability Control), 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.
VSA
® Operation
VSA
® (Vehicle Stability Assist), aka ESC (Electronic Stability
Control), System
The VSA
® may not function properly 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
® 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 vehicle 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 Stability Control (ESC). The
system also includes a traction control function.
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
® On and Off
This button is on the driver side control
panel. To turn the VSA
® system on and off,
press and hold it until you hear a beep.
VSA
® will stop and the indicator will come
on.
To turn it on again, 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
® (Vehicle Stability Assist), aka ESC (Electronic Stability
Control), System
Without VSA
®, your vehicle will have normal braking
and cornering ability, but it will not have VSA
®
traction and stability enhancement.
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 VSA
® on again. We do not recommend
driving your vehicle with the VSA
® and traction
control systems switched off.
If the low tire pressure/ TPMS indicator comes on or
blinks, the VSA
® system comes on automatically.
In this case, you cannot turn the system off by
pressing the

button.
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.

Checking and Maintaining Tires
DOT Tire Quality Grading (U.S. Vehicles)
262Maintenance
DOT Tire Quality Grading (U.S. Vehicles)The tires on your vehicle meet all U.S. Federal Safety Requirements. All
tires are also graded for treadwear, traction, and temperature performance
according to Department of Transportation (DOT) standards. The following
explains these gradings.
Uniform Tire Quality Grading
Quality grades can be found where applicable on the tire sidewall between
tread shoulder and maximum section width.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the
tire when tested under controlled conditions on a specified 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 performance of tires depends upon the actual conditions of their
use, however, and may depart significantly from the norm due to variations
in driving habits, service practices and differences in road characteristics
and climate.
Uniform Tire Quality GradingFor example:
Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.

Checking and Maintaining Tires
DOT Tire Quality Grading (U.S. Vehicles)
263
Maintenance
Traction
The traction grades, from 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 specified government test
surfaces of asphalt and concrete. A tire marked C may have poor traction
performance.
Temperature
The temperature grades are A (the highest), B, and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
Trac tionWarning: The traction grade assigned to
this tire is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning, or
peak traction characteristics. TemperatureWarning: The temperature grade for
this tire is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
