Driving your vehicle
Your vehicle speed can be reduced
due to a vehicle in the adjacent lane.
Apply the accelerator pedal and
select the appropriate set speed.
Check to be sure that the road con-
ditions permit safe operation of the
Smart Cruise Control.
On inclines
During uphill or downhill driving, the Smart Cruise Control system
may not detect a moving vehicle in
your lane, and cause your vehicle
to accelerate to the set speed.
Also, the vehicle speed will rapidly
decrease when the vehicle ahead
is recognized suddenly.
Select the appropriate set speed on inclines and apply the brake or
accelerator pedal if necessary.
Lane changing
A vehicle which moves into yourlane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.
The radar may not detect immedi- ately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.
If a slower vehicle moves into your lane, your speed may decrease to
maintain the distance to the vehicle
ahead.
If a faster vehicle which moves into your lane, your vehicle will acceler-
ate to the set speed.

Detecting vehicles
Some vehicles in your lane cannot
be recognized by the sensor:
- Narrow vehicles such as motorcy-cles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden- decelerating vehicles
- Stopped vehicles
- Vehicles with small rear profile such as trailers with no loads A vehicle ahead cannot be recog-
nized correctly by the sensor if any of
following occurs:
- When the vehicle is pointing
upwards due to overloading in the
luggage compartment
- While the steering wheel is operat- ing
- When driving to one side of the lane
- When driving on narrow lanes or on curves
Apply the brake or accelerator pedal
if necessary. Your vehicle may accelerate when
a vehicle ahead of you disappears.

What to do in an emergency
6
When towing your vehicle in an
emergency without wheel dollies:
1. Place the ignition switch in theACC position.
2. Place the shift lever in N (Neutral).
3. Release the parking brake.Dinghy Towing
Your vehicle is not designed to be
dinghy towed (with 4 wheels on the
ground) behind a motor home. To
avoid serious damage to your vehi-
cle, do not tow your vehicle with four
wheels on the ground.
If your vehicle is equipped with
a rollover sensor, place the igni-
tion switch in the LOCK/OFF or
ACC position when the vehicle
is being towed. The side impact
and curtain air bag may deploy
if the sensor detects the situa-
tion as a rollover.
WARNING
Failure to place the shift lever in
N (Neutral) when being towed
with the front wheels on the
ground can cause internal dam-
age to the transmission.

Exterior Care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning
and caution statements that appear
on the label.
High-pressure washing
When using high-pressure wash-
ers, make sure to maintain suffi-
cient distance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
Do not spray the camera, sensors or its surrounding area directly with
a high pressure washer. Shock
applied from high pressure water
may cause the device to not oper-
ate normally.
Do not bring the nozzle tip close to boots (rubber or plastic covers)or
connectors as they may be dam-
aged if they come into contact with
high pressure water.
Do not use any high-pressure noz- zles, which induce either one-direct
water stream or water swirling.
Protecting your vehicle’s finish
Washing
To help protect your vehicle’s finish
from rust and deterioration, wash it
thoroughly and frequently at least
once a month with lukewarm or cold
water.
If you use your vehicle for off-road
driving, you should wash it after each
off-road trip. Pay special attention to
the removal of any accumulation of
salt, dirt, mud, and other foreign
materials. Make sure the drain holes
in the lower edges of the doors and
rocker panels are kept clear and
clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar
deposits can damage your vehicle’s
finish if not removed immediately.
Even prompt washing with plain
water may not completely remove all
these deposits. A mild soap, safe for
use on painted surfaces, should be
used.
After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the fin-
ish. Do not use strong soap, chemi-
cal detergents or hot water, and
do not wash the vehicle in direct
sunlight or when the body of the
vehicle is warm.
Be careful when washing the side windows of your vehicle.
Especially, with high-pressure
water, water may leak through
the windows and wet the interi-
or.
To prevent damage to the plastic parts, do not clean with chemi-
cal solvents or strong deter-
gents.
NOTICE
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water before getting on the
road. If braking performance is
impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.
