To start a vehicle, with your right
foot pressing the accelerator pedal
down fully, remove your left foot
from the brake. (within 4 seconds)
(Launch Control Active (2) Status
Display on Cluster Screen)
If both the brakes and accelerater
pedals were applied and the driver
removes his foot only from the
accelerater pedal, Launch Control
will be automatically deactivated. Or,
if the vehicle does not start after 4
seconds with a driver’s feet on both
brake and accelerate pedals,
Launch Control will automatically
deactivated as well. Do not operate both brake and
accelerate pedals simultaneously
for longer than 4 seconds.
When re-using Launch Control, a
driver should have the vehicle cool
down sufficiently by driving.
Limited use of Launch Control (3)
An warning message will pop up
on the screen if the transmission
fluid temperature is above a certain
level while using Launch Control.
Also, Launch Control will be auto-
matically deactivated.
To address the issue as above, a
driver should cool down the trans-
mission fluid temperature by driv-
ing the vehicle. (Driving at a con-
stant speed over 37 mph (60 km/h)
is highly recommended, but this
should only be done if traffic and
road conditions permit the driver to
do so safely.)

When certain conditions are met, the
engine is automatically decoupled
from the transmission while the shift
lever is remained in D (Drive). In this
ECO Coasting mode, the engine
stays at idling speed to reduce fuel
consumption and increase coasting
distance. The engine is automatically
coupled back again when ECO
Coasting deactivation conditions are
met. Please refer to ECO Coasting
activation and deactivation condi-
tions.
The Eco-Coasting system set-
ting
The Eco-Coasting system activates
if select the Eco-Coasting system
from AVN : "Setting Vehicle 
Coasting" (Please refer to AVN man-
ual for more details.)
When the Eco-Coasting system is
activated, the message "Coasting"
appears at the top center of the clus-
ter.
Eco-Coasting operation condi-
tions
The Eco-Coasting system is activat-
ed when the accelerator pedal is
depressed and released under the
following conditions.
When the driving mode is ECO
mode.
When driver acceleration is
SMART ECO in SMART mode.
When the shift lever is in the D
(Drive) position.
When Cruise Control/Smart Cruise
Control button is OFF.
The accelerator or brake pedal is
not depressed.
When the vehicle speed is within
the range of 35 mph (55 km/h) to
100 mph (160 km/h).

range of -5% to +5%.
In SMART mode, if the distance
between the vehicle ahead and the
relative speed is within a certain
range (if Smart Cruise Control
system is equipped)
THE ECO-COASTING SYSTEM (IF EQUIPPED)
CAUTION
If the accelerator pedal is
pressed quickly for accelerat-
ing with the Eco-Coasting sys-
tem in operation, acceleration
may occur after the engage-
ment of the clutch inside the
transmission. In turn, the driv-
er may continue to feel accel-
eration even after the system
is turned off.
Driving with the Eco-Coasting
system off may be required in
some cases since the engine
brake is not applied while the
Eco-Coasting system is in
operation.
Operation the AVN screen to
activate or deactivate Eco-
Coasting system while driving
may be dangerous as the dri-
ver's attention is dispersed.

✽ ✽
NOTICE
• Do not drive in water if the level is
higher than the bottom of the vehi-
cle.
• Check your brake condition once
you are out of mud or water.
Depress the brake pedal several
times as you move slowly until you
feel normal braking return.
• Shorten your scheduled mainte-
nance interval if you drive in off-
road conditions such as sand, mud
or water (see "Maintenance Under
Severe Usage Conditions" in chap-
ter 7).
• Make sure that AWD vehicle is
towed by a flatbed tow truck.
For safe AWD operation
Before driving
Make sure all passengers are
wearing seat belts.
Sit upright and closer to the steer-
ing wheel than usual. Adjust the
steering wheel to a position com-
fortable for you to drive.
Driving on snow-covered or icy roads
Start off slowly by applying the
accelerator pedal gently.
Use snow tires or tire chains.
Keep sufficient distance between
your vehicle and the vehicle in front
of you.
Use engine braking during deceler-
ation.
Avoid speeding, rapid acceleration,
sudden brake applications, and
sharp turns to prevent skids.Driving in sand or mud
Maintain slow and constant speed.
Use tire chains driving in mud if
necessary.
Keep sufficient distance between
your vehicle and the vehicle in front
of you.
Reduce vehicle speed and always
check the road condition.
Avoid speeding, rapid acceleration,
sudden brake applications, and
sharp turns to prevent getting
stuck.
✽ ✽
NOTICE
When the vehicle is stuck in snow,
sand or mud, place a non-slip mate-
rial under the drive wheels to pro-
vide traction OR slowly spin the
wheels in forward and reverse direc-
tions which causes a rocking motion
that may free the vehicle. See the
Section "Rocking the Vehicle" for
more details. However, avoid run-
ning the engine continuously at high
rpm, which could damage the AWD
system.

Driving your vehicle
Towing
AWD vehicles must be towed with a
wheel lift and dollies or flatbed equip-
ment with all the wheels off the
ground. For more information, refer
to "Towing" in chapter 6.
Vehicle inspection
When the vehicle is on a car lift, do
not operate the front and rear
wheels separately. All four wheels
should be operated.
Never engage the parking brake
while running the engine on a car
lift. This may damage the AWD
system.WARNING
Never start or run the engine
while an AWD vehicle is raised
on a jack. The vehicle can slip or
roll off of a jack causing serious
injury or death to you or those
nearby.

LIMITED SLIP
DIFFERENTIAL (LSD)
(IF EQUIPPED)
Dynamometer testing
An AWD vehicle must be tested on a
special four wheel chassis
dynamometer.
An AWD vehicle should not be tested
on a 2WD roll tester. If a 2WD roll
tester must be used, perform the fol-
lowing procedure:1. Check the tire pressures recom-
mended for your vehicle.
2. Place the rear wheels on the roll
tester for a speedometer test as
shown in the illustration.
3. Release the parking brake.
4. Place the front wheels on the tem-
porary free roller as shown in the
illustration.Limited Slip Differential (LSD) refers
to a system equipped with a mecha-
nism that controls the differential
functions of the wheels in the Rear-
Differential. It allows for an enhance-
ment in handling performance during
turning.
Never run wheels with one of them
lifted by the jack. It is extremely dan-
gerous for a vehicle equipped with
Limited Slip Differential.
Be sure to inject oil for exclusive use
of LSD when replacing Rear
Differential (for LSD) Oil.
✽ ✽
NOTICE
There could be slight noises coming
from friction plates inside LSD
when the LSD-equipped vehicle is
turning around, but it is a normal
sound in the process of LSD opera-
tion and the noises don’t indicate
vehicle failure.
Oil change is highly recommended in
case that the sound becomes louder.
WARNING
Keep away from the front of the
vehicle while the vehicle is in
gear on the dynamometer. The
vehicle can jump forward and
cause serious injury or death.

Driving your vehicle
Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
In the event that the power-assisted
brakes lose power because of a
stalled engine or some other reason,
you can still stop your vehicle by
applying greater force to the brake
pedal than you normally would. The
stopping distance, however, will be
longer.
When the engine is not running, the
reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.Wet brakes may impair the vehicle’s
ability to safely slow down; the vehi-
cle may also pull to one side when
the brakes are applied. Applying the
brakes lightly will indicate whether
they have been affected in this way.
Always test your brakes in this fash-
ion after driving through deep water.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
BRAKE SYSTEM
WARNING- Steep hill
braking
Avoid continuous application of
the brakes when descending a
long or steep hill by shifting to a
lower gear. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
CAUTION- Brake Pedal
Do not drive with your foot rest-
ing on the brake pedal. This will
create abnormally high brake
temperatures which can cause
excessive brake lining and pad
wear.

In the event of brake failure
If the service brakes fail to operate
while the vehicle is in motion, you
can make an emergency stop with
the parking brake. The stopping dis-
tance, however, will be much greater
than normal.
Disc brakes wear indicator
When your brake pads are worn and
new pads are required, you will hear
a high-pitched warning sound from
your front brakes or rear brakes. You
may hear this sound come and go or
it may occur whenever you depress
the brake pedal.
Please remember that some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
Always replace the front or rear
brake pads as pairs.
WARNING- Parking
brake
Avoid applying the parking
brake to stop the vehicle while it
is moving except in an emer-
gency situation. Applying the
parking brake while the vehicle
is moving at normal speeds can
cause a sudden loss of control
of the vehicle. If you must use
the parking brake to stop the
vehicle, use great caution in
applying the brake.
WARNING- Brake wear
Do not ignore high pitched wear
sounds from your brakes. If you
ignore this audible warning, you
will eventually lose braking per-
formance, which could lead to a
serious accident.
CAUTION- Replace brake
pads
Do not continue to drive with
worn brake pads. Continuing to
drive with worn brake pads can
damage the braking system and
result in costly brake repairs.

545
Driving your vehicle
Brembo Brake (if equipped)
It is normal for vehicles equipped
with high-performance brakes
(Large-diameter Brembo brakes for
enhanced braking performance) to
generate braking noises.
Also, Circular patterns caused by
disc surface friction may occur.
These patterns are normal and do
not affect braking performance.
Parking brake – Foot type
(if equipped)
Applying the parking brake
To engage the parking brake, first
apply the foot brake and then
depress the parking brake pedal
down as far as possible.
OCK058198
CAUTION
Excessive, high speed, repeti-
tive braking may cause abnor-
mal deformation and wear of
parts even if high performance
brakes are equipped on the
vehicle. This wear can cause
vehicle vibration when braking.
Drivers should obey speed lim-
its and avoid excessive, high
speed, repetitive braking to pre-
vent damage. The limited war-
ranty does not cover damage
caused by excessive, high
speed, repetitive braking, track
driving, racing, or other abuse
or misuse of the vehicle.
