ESC OFF usage
When driving
ESC should be turned on for dailydriving whenever possible.
To turn ESC off while driving, press the ESC OFF button while driving
on a flat road surface.
✽ ✽ NOTICE
• When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off (ESC OFF light
illuminated). If the ESC is left on,
it may prevent the vehicle speed
from increasing, and result in false
diagnosis.
• Turning the ESC off does not affect ABS or brake system opera-
tion.
Vehicle stability management
(VSM)
This system provides further
enhancements to vehicle stability
and steering responses when a vehi-
cle is driving on a slippery road or a
vehicle detects changes in coeffi-
cient of friction between right wheels
and left wheels when braking.
WARNING- Operating
ESC
Never press the ESC OFF but-
ton while ESC is operating (ESC
indicator light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip
out of control.
WARNING- Tire/ Wheel size
When replacing tires and wheels,
make sure they are the same size
as the original tires and wheels
installed. Driving with varying
tire or wheel sizes may diminish
any supplemental safety benefits
of the VSM system.

Detecting vehicles
The sensor may be limited when:
The radar sensor or camera is cov-ered with a foreign object or debris
The camera lens is contaminated due to tinted, filmed or coated
windshield, damaged glass, or
stuck of foreign matter (sticker,
bug, etc.) on the glass
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera
There is interference by electro- magnetic waves
Something in the path of travel deflects the radar waves.
The radar/camera recognition is limited
The vehicle in front is too small to be detected (for example a motor-
cycle or a bicycle, etc.)
The vehicle in front is an oversize vehicle or trailer that is too big to
be detected by the camera recog-
nition system. (for example a trac-
tor, trailer, etc.) The camera's field of view is not well
illuminated (either too dark or too
much reflection or too much back-
light that obscures the field of view)
The vehicle in front does not have their rear lights properly turned ON
or their rear lights are located
unusually.
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel
When light coming from a street light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle in the road
The field of view in front is obstructed by sun glare or head-
light of oncoming vehicle.
The windshield glass is fogged up
The vehicle in front is driving errat- ically
The vehicle is on unpaved or uneven rough surfaces, or roads
with sudden gradient changes The vehicle is driven near areas
containing metal substances as a
construction zone, railroad, etc.

The camera does not recognize the entire vehicle in front.
The camera is damaged.
The brightness outside is too low such as when the headlamps are
not on at night or the vehicle is
going through a tunnel.
Adverse road conditions cause excessive vehicle vibrations while
driving
The sensor recognition changes suddenly when passing over a
speed bump
The shadow is on the road by a median strip, trees, etc.

Severe weather conditions in the
winter result in greater wear and
other problems. To minimize the
problems of winter driving, you
should follow these suggestions:Snowy or icy conditions
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
If snow tires are needed, it is neces-
sary to select tires equivalent in size
and type of the original equipment
tires. Failure to do so may adversely
affect the safety and handling of your
vehicle. Furthermore, speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause skids to occur. You
need to keep sufficient distance
between the vehicle in operation in
front of your vehicle. Also, apply the
brake gently. It should be noted that
installing tire chains on the tire will
provide a greater driving force, but
will not prevent side skids.
Tire chains are not legal in all states.
Check state laws before fitting tire
chains.
Snow tires
If you mount snow tires on your vehi-
cle, make sure they are radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
Keep in mind that the traction provid-
ed by snow tires on dry roads may
not be as high as your vehicle's orig-
inal equipment tires. You should drive
cautiously even when the roads are
clear. Check with the tire dealer for
maximum speed recommendations.
Do not install studded tires without
first checking local, state and munic-ipal regulations for possible restric-tions against their use.
WINTER DRIVING
WARNING - Snow tire size
Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your vehi-
cle may be adversely affected.

Tire chains
Since the sidewalls of radial tires are
thinner, they can be damaged by
mounting some types of snow chains
on them. Therefore, the use of snow
tires is recommended instead of
snow chains. Do not mount tire
chains on vehicles equipped with
aluminum wheels; snow chains may
cause damage to the wheels. If snow
chains must be used, use wire-type
chains with a thickness of less than
0.47 in (12 mm). Damage to your
vehicle caused by improper snow
chain use is not covered by your
vehicle manufacturers warranty.When using tire chains, attach them
to the drive wheels as follows.
FWD : Front wheels
The snow chain connecting hooks
may be damaged from contacting
vehicle components causing the
snow chains to come loose from the
tire. Make sure the snow chains are
SAE class “S” certified.
Always check chain installation for
proper mounting after driving
approximately 0.3 to 0.6 miles (0.5 to
1 km) to ensure safe mounting.
Retighten or remount the chains if
they are loose.
Chain installation
When installing chains, follow the
manufacturer's instructions and
mount them as tightly as possible.
Drive slowly with chains installed. If
you hear the chains contacting the
body or chassis, stop and tighten
them. If they still make contact, slow
down until it stops. Remove the
chains as soon as you begin driving
on cleared roads.
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning flashers and place a
triangular emergency warning device
behind the vehicle if available.
Always place the vehicle in P (Park),
apply the parking brake and turn off
the engine before installing snow
chains.
CAUTION- Snow chains
Make sure the snow chains are
the correct size and type foryour tires. Incorrect snowchains can cause damage to thevehicle body and suspensionand may not be covered by yourvehicle manufacturer warranty.

What to do in an emergency
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle’s handling and
stopping ability.Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tire pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the system
may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the TPMS
to continue to function properly.

To prevent the jack, wheel lug nut
wrench and spare tire from rattling
while the vehicle is in motion, store
them properly.
Check the inflation pressures as
soon as possible after installing the
spare tire. Adjust it to the specified
pressure, if necessary. Refer to
“Tires and wheels” in section 8.
Important - use of compact spare
tire
Your vehicle is equipped with a com-
pact spare tire. This compact spare
tire takes up less space than a regu-
lar-size tire. This tire is smaller than a
conventional tire and is designed for
temporary use only.
You should drive carefully when the compact spare is in use. The
compact spare should be replaced
by the proper conventional tire and
rim at the first opportunity.
The operation of this vehicle is not recommended with more than one
compact spare tire in use at the
same time. The compact spare should be inflat-
ed to 60 psi (420 kPa).
✽ ✽
NOTICE
Check the inflation pressure after
installing the spare tire. Adjust it to
the specified pressure, as necessary.
WARNING- Spare tire
The compact spare tire is for
emergency use only. Do not
operate your vehicle on this
compact spare at speeds over
50 mph (80 km/h). The original
tire should be repaired or
replaced as soon as possible to
avoid failure of the spare possi-
bly leading to personal injury or
death.WARNING- Wheel studs
If the studs are damaged, they
may lose their ability to retain
the wheel. This could lead to the
loss of the wheel and a collision
resulting in serious injuries.

What to do in an emergency
When using a compact spare tire,
observe the following precautions:
Under no circumstances shouldyou exceed 50 mph (80 km/h); a
higher speed could damage the
tire.
Ensure that you drive slowly enough for the road conditions to
avoid all hazards. Any road hazard,
such as a pothole or debris, could
seriously damage the compact
spare.
Any continuous road use of this tire could result in tire failure, loss of
vehicle control, and possible per-
sonal injury.
Do not exceed the vehicle’s maxi- mum load rating or the load-carry-
ing capacity shown on the sidewall
of the compact spare tire.
Avoid driving over obstacles. The compact spare tire diameter is
smaller than the diameter of a con-
ventional tire and reduces the
ground clearance approximately 1
inch (25 mm), which could result in
damage to the vehicle. Do not take this vehicle through an
automatic vehicle wash while the
compact spare tire is installed.
Do not use tire chains on the com- pact spare tire. Because of the
smaller size, a tire chain will not fit
properly. This could damage the
vehicle and result in loss of the
chain.
Do not use the compact spare tire on any other vehicle because this
tire has been designed especially
for your vehicle.
The compact spare tire’s tread life is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.
The compact spare tire should not be used on any other wheels, nor
should standard tires, snow tires,
wheel covers or trim rings be used
with the compact spare wheel. If
such use is attempted, damage to
these items or other vehicle com-
ponents may occur. Do not use more than one compact
spare tire at a time.
Do not tow a trailer while the com- pact spare tire is installed.
