Important Safety Reminder
The main purpose of the CMBS is to
reduce the severity of injuries caused
by an unavoidable collision. While
the CMBS may help to alert you and
minimize the severity of a collision, it
may not activate in every dangerous
situation.
Even with the CMBS, it is still your
responsibility to operate the brake
pedal and steering wheel
appropriately, according to the
driving conditions.
As required by the FCC:This device complies with Part 15 ofthe FCC rules. Operation is subjectto the following two conditions: (1)

Integrated Dynamics System
(IDS)If equippedThe integrated dynamics system
(IDS) is always on, constantly
adjusting your vehicle's dampers and
power steering assist according to
current road conditions, vehicle
speed and handling. You can choose
between two settings, sport mode
and comfort mode, according to your
driving taste.
Sport ModeThe system prioritizes handling
response for higher handling
performance.Comfort modeThe system prioritizes driving
comfort according to the road
surface.
There are two main components to
IDS that work together in both
modes:
The active damper system (ADS)
uses electrically controlled dampers
to enhance handling precision, tire to
road adhesion and riding comfort on
rough road surfaces.
The electronically controlled power
steering (ECPS) changes the amount
of steering assist depending on
vehicle speed.

Active Damper System
Indicator
If there is a problem with the active
damper system, the system shuts
down and the active damper system
indicator on the instrument panel
comes on.
You will also see the ‘‘CHECK ADS
SYSTEM ’’message appear on the
multi-information display. In addition, the ECPS also defaults
into sport mode, and you will see the
‘‘
CHECK POWER STEERING
SYSTEM ’’message appear on the
multi-information display (see page
91).
If you see this warning indicator and
message, have your vehicle checked
at your dealer as soon as possible.
In this case, your vehicle still has the
normal damper function, but it will
not have the active damper function.
Electronically Controlled
Power Steering System
(ECPS) Indicator
If there is a problem with the
Electronically Controlled Power
Steering System, the system shuts
down and the system indicator on
the instrument panel comes on.
You will also see the ‘‘CHECK
POWER STEERING SYSTEM’’
message appear on the multi-
information display.
If you see this warning indicator and
message, have your vehicle checked
at your dealer as soon as possible.
In this case, your vehicle still has the
power steering function, but the
steering effort might feel different.

Tongue LoadThe weight that the tongue of a fully
loaded trailer puts on the hitch
should be approximately 10% of the
total trailer weight.
Too much tongue load reduces front-
tire 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 loading 60% of the load
toward the front of the trailer and 40%
toward the rear, then re-adjust the
load as needed.
Gross Vehicle Weight Rating
(GVWR)
－The maximum allowable
weight of the vehicle, all occupants,
all accessories, all cargo, and the
tongue load is 5,534 lbs (2,510 kg).
Gross Axle Weight Ratings
(GAWR) －The maximum allowable
weight of the vehicle, all occupants,
all accessories, all cargo, and the
tongue load must not exceed 2,921
lbs (1,325 kg) on the front axle, and
2,679 lbs (1,215 kg) on the rear axle.
Gross Combined Weight Rating
(GCWR) －The maximum allowable
weight of the fully loaded vehicle and
trailer is 6,593 lbs (2990 kg). Checking Loads
The best way to confirm that all loads
are within limits is to check them at a
public scale. For public scales in your
area, check your local phone book,
or contact your trailer dealer or
rental agency for assistance.
If you cannot get to a public scale,
you can estimate the total trailer
weight by adding the weight of your
trailer (as quoted by the
manufacturer) with everything in or
on the trailer.
If you normally pull the same load
each time you tow a trailer, you can
use a suitable scale or a special
tongue load gauge to check the
tongue load the first time you set up
a towing combination (a fully loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.

Driving on HillsWhen climbing hills, closely watch
your temperature gauge. If it nears
the H (Hot) mark, turn the A/C off,
reduce speed and, if necessary, pull
to the side of the road to let the
engine cool.
When driving down hills, reduce
your speed, and shift down to S
position, or use the paddle shifters to
the lower gear (3 and 2) in the S
position. When towing a trailer, do
not‘‘ride ’’the brakes, and remember,
it will take longer to slow down and
stop when towing a trailer.
If you must stop when facing uphill,
use the foot brake or parking brake.
Do not try to hold the vehicle in place
by pressing on the accelerator, as
this can cause the automatic
transmission to overheat.
Handling Crosswinds and BuffetingCrosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.Backing UpAlways drive slowly and have
someone guide you when backing
up. Grip the
bottom
of the steering
wheel, then turn the wheel to the left
to get the trailer to move to the left.
Turn the wheel to the right to move
the trailer to the right.
ParkingFollow all normal precautions when
parking, including putting the
transmission in Park and firmly
setting the parking brake. Also, place
wheel chocks at each of the trailer's
tires. Towing Your Vehicle
Your vehicle is not designed to be
towed behind a motor home. If your
vehicle needs to be towed in an
emergency, see page 602.

Your vehicle displays engine oil life
and maintenance service items on
the multi-information display to show
you when you should have your
dealer perform engine oil
replacement and indicated
maintenance service.
Based on the engine operating
conditions and accumulated engine
revolutions, the onboard computer in
your vehicle calculates the remaining
engine oil life and displays it as a
percentage.Engine Oil Life Display
To see the current engine oil life
displayed on the multi-information
display, turn the ignition switch to
the ON (II) position, and press the
SEL/RESET button on the steering
wheel repeatedly until the engine oil
life is displayed.Models equipped with the keyless
access system have an engine start/
stop button instead of an ignition
switch. ON mode is the equivalent of
ON (II). See page 196 for ignition
switch and power mode comparison.
