CAUTION
ODN8A069212
If the vehicle ahead (vehicle speed:
less than 20 mph (30 km/h)) disappears
to the next lane, the warning chime
will sound and a message "Watch for
surrounding vehicles" will appear.
Adjust your vehicle speed for vehicles
or objects that can suddenly appear in
front of you by depressing the brake
pedal.
Always pay attention to the road
condition ahead.
In traffic situation
OOSH069118L
Use switch or pedal to accelerate
• In traffic, your vehicle will stop if the
vehicle ahead of you stops. Also,
if the vehicle ahead of you starts
moving, your vehicle will start as well.
However, if the vehicle stops for more
than 3 seconds, you must depress
the accelerator pedal or push up the
toggle switch (RES+) to start driving.
• If you push Smart Cruise Control
toggle switch (RES+ or SET-) while
Auto Hold and smart cruise control
is operating the Auto Hold will be
released regardless of accelerator
pedal operation and the vehicle
will start to move. The AUTO HOLD
indicator changes from green to
white.

System Setting and Operation
System setting
• With the Engine Start/Stop button in
the ON or START position, Navigation-
based Smart Cruise Control can
be activated by selecting 'Driver
Assistance
→ Highway Auto Curve
Slowdown' from the User Settings
mode on the infotainment system.
For detailed information, please refer
to the infotainment system manual
separately supplied.
• If the engine is turned off then on
again, the system maintains the last
setting.
Operating conditions
Select 'Highway Auto Curve Slowdown'
from the Settings menu in the
infotainment system screen and satisfy
the following conditions for the system
to operate.
• Driving on the highway main line
• Smart Cruise Control is operating
If all the mentioned conditions are
satisfied, the system is ENABLED and
the 'AUTO' symbol on the cluster will
illuminate white.
System operation
ODN8A069213
System standby
If the system is ENABLED, the

symbol on the cluster will illuminate
white.
ODN8A069214
System in operation
If the vehicle decelerates in a curve,
the
symbol on the cluster will
illuminate green.
• This system works only for curved
sections located on highway main
lines.
• Depending on the curve ahead on the
road, the vehicle will decelerate, and
after passing curve, the vehicle will
accelerate to Smart Cruise Control set
speed.
• The higher the driving speed, the
faster the vehicle is decelerated.
• The system responds to curves
located on the destination set in the
navigation. If the destination is not
set, the system will respond to road
information of the expected route.

Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water, snow,
ice, mud and sand, take the below
suggestions:
• Drive cautiously and keep a longer
braking distance.
• Avoid abrupt braking or steering.
• When your vehicle is stuck in
snow, mud, or sand, use second
gear. Accelerate slowly to avoid
unnecessary wheel spin.
• Put sand, rock salt, tire chains or other
non-slip materials under the wheels to
provide additional traction while the
vehicle becomes stuck in ice, snow,
or mud.
WARNING
Downshifting with an automatic
transmission while driving on slippery
surfaces can cause an accident. The
sudden change in tire speed could
cause the tires to skid. Be careful when
downshifting on slippery surfaces.
Rocking the Vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between R (Reverse)
and a forward gear.
Try to avoid spinning the wheels, and do
not race the engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on the
accelerator pedal while the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes a
rocking motion that may free the vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
of the tires can increase very quickly.
If the tires become damaged, a tire
blow out or tire explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire
or other damage. Try to avoid spinning
the wheels as much as possible to
prevent overheating of either the tires
or the engine. DO NOT allow the vehicle
to spin the wheels above 35 mph (56
km/h).
Information
The ESC system must be turned OFF
before rocking the vehicle.
NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage to
the transmission, and tire damage. See
"Towing" in chapter 7.

While Driving

Maintenance
8-6
While operating your vehicle:
• Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering
wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.
• Notice if your vehicle constantly turns
slightly or “pulls” to one side when
traveling on smooth, level road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the
operation of your transmission occurs,
check the transmission fluid level.
• Check the automatic transmission P
(Park) function.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the brake lights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all
tires including the spare for tires that
are worn, show uneven wear, or are
damaged.
• Check for loose wheel lug nuts.
At least twice a year:
(i.e., every Spring and Autumn)
• Check radiator, heater and air
conditioning hoses for leaks or
damage.
• Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer a fluid.
• Check headlamp alignment.
• Check muffler, exhaust pipes, shields
and clamps.
• Check the seat belts for wear and
function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and hood
hinges.
• Lubricate door and hood locks and
latches.
• Lubricate door rubber weather strips.
• Lubricate door checker.
• Check the air conditioning system.
• Inspect and lubricate automatic
transmission linkage and controls.
• Clean the battery and terminals.
• Check the brake fluid level.
