RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only
lubricants of the proper quality. The correct lubricants also help promote engine
efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

chapter 1.
*1 : Refer to the recommended SAE viscosity numbers on page 12.
*2 : Engine oils labeled Energy Conserving Oil are now available. Along with other additional
benefits, they contribute to fuel economy by reducing the amount of fuel necessary
to overcome engine friction. Often, these improvements are difficult to measure in
everyday driving, but in a year’s time, they can offer significant cost and energy savings.
*3 : If the recommended engine oil is not available in your country, you are able to use API
SL/ILSAC GF-3 or ACEA A3.
*4 : To maintain the best braking performance and ABS/ESC performance, we recommend
that you use genuine brake fluid that conform to specifications. (Standard : SAE J1704
DOT-4 LV, ISO4925 CLASS-6 and FMVSS 116 DOT-4)

Automatic Transmission Operation
The automatic transmission has six forward speeds and one reverse speed. The
individual speeds are selected automatically in the D (Drive) position. The indicator in
the instrument cluster displays the shift button position when the ignition switch is in
the ON position.
WARNING
The automatic transmission shift button or interior parts might get hot when a
vehicle is parked outside during hot weather. Always be careful when the vehicle is
hot.
AUTOMATIC TRANSMISSION

WARNING
To reduce the risk of serious injury or
death:
• ALWAYS check the surrounding
areas near your vehicle for people,
especially children, before shifting a
vehicle into D (Drive) or R (Reverse).
• Before leaving the driver’s seat,
always make sure the gear is in
the P (Park) position, then set
the parking brake, and place the
ignition switch in the LOCK/OFF
position. Unexpected and sudden
vehicle movement can occur if these
precautions are not followed.
• If equipped, do not use the engine
brake (shifting from a high gear to
lower gear using the paddle shifters)
rapidly on slippery roads.
P (Park)
Always come to a complete stop before
shifting into P (Park).
To shift from P (Park), you must depress
firmly on the brake pedal and make sure
your foot is off the accelerator pedal.
The gear must be in P (Park) before
turning the engine off.
WARNING
• Shifting into P (Park) while the
vehicle is in motion may cause you to
lose control of the vehicle.
• After the vehicle has stopped, always
make sure the gear is in P (Park),
apply the parking brake, and turn
the engine off.
• Do not use the P (Park) position in
place of the parking brake.
R (Reverse)
Use this position to drive the vehicle
backward.
NOTICE
Always come to a complete stop before
shifting into or out of R (Reverse); you
may damage the transmission if you
shift into R (Reverse) while the vehicle is
in motion.
When the vehicle is stopped in
R (Reverse) position, if you open
the driver's door with the seat belt
unfastened, the gear is shifted to P (Park)
position automatically.
However when the vehicle moves
in R (Reverse) position, if you open
the driver's door with the seat belt
unfastened, the gear may be not shifted
to P (Park) position automatically for
protecting the automatic transmission.
N (Neutral)
The wheels and transmission are not
engaged.
Shift into P (Park) if you need to leave
your vehicle for any reason.
Always depress the brake pedal when
you are shifting from N (Neutral) to
another gear.
WARNING
Do not shift into gear unless your foot is
firmly on the brake pedal. Shifting into
gear when the engine is running at high
speed can cause the vehicle to move
very rapidly. You could lose control of
the vehicle and hit people or objects.

While Driving
6-12
D (Drive)
This is the normal driving position. The
transmission will automatically shift
through a 6-gear sequence, providing
the best fuel economy and power.
To start the vehicle forward, push the D
(Drive) button by depressing the brake
pedal with the engine ON. Then depress
the accelerator pedal smoothly.
For extra power when passing another
vehicle or driving uphill, depress the
accelerator fully. The transmission will
automatically downshift to the next
lower gear (or gears, as appropriate).
When the vehicle is stopped in D (Drive)
position, if you open the driver's door
with the seat belt unfastened, the gear is
shifted to P (Park) position automatically.
However when the vehicle moves in D
(Drive) position, if you open the driver's
door with the seat belt unfastened, the
gear may not shift to P (Park) position
automatically to protect the automatic
transmission.
Shift-lock system
For your safety, the automatic
transmission has a shift-lock system
which prevents shifting the gear from
P (Park) or N (Neutral) to R (Reverse)
or D (Drive) unless the brake pedal is
depressed.
To shift the gear from P (Park) or N
(Neutral) to R (Reverse) or D (Drive):
1. Depress and hold the brake pedal.
2. Start the engine.
3. Depress the brake pedal and push the
R (Reverse) or D (Drive) button.
Stay in N (Neutral) position when
engine is Off
ODN8069006
ODN8069008
If you want to keep the N (Neutral)
position after the engine is OFF, do the
following.
1. Deactivate the AUTO HOLD and
release the parking brake when the
ignition switch or the engine is ON.
2. Push the N (neutral) button while
depressing the brake pedal. If the
message ("Press and hold OK button
to stay in Neutral when vehicle is
OFF") appears on the cluster LCD
display, press and hold the OK button
on the steering wheel for more than 1
second.

While Driving

CUSTOM mode
In CUSTOM mode, the driver can select separate modes
and combine them on the
infotainment system screen.
-Engine/Transmission: ECO/SPORT
-Steering wheel: SPORT
For more details, refer to the separately
supplied manual with your vehicle.
• When CUSTOM mode is selected
by using the DRIVE MODE button,
the CUSTOM mode indicator will
illuminate.
ECO mode
When the Drive Mode is set
to ECO mode, the engine and
transmission control logic are
changed to maximize fuel
efficiency.
• When the ECO mode is selected by
using the DRIVE MODE button, the
ECO indicator will illuminate.
• Whenever the engine is restarted, the
drive mode remains in ECO mode.
Information
Fuel efficiency depends on the driver’s
driving habit and road condition.
When ECO mode is activated:
• The acceleration response may be
slightly reduced as the accelerator
pedal is depressed moderately.
• The air conditioner performance may
be limited.
• The shift pattern of the automatic
transmission may change.
• The engine noise may get louder.
The above situations are normal
conditions when ECO mode is activated
to improve fuel efficiency.
Limitation of ECO mode operation:
If the following conditions occur while
ECO mode is operating, the system
operation is limited even though there is
no change in ECO indicator.
• When the coolant temperature is low:
The system will be limited until engine
performance becomes normal.
• When driving up a hill:
The system will be limited to gain
power when driving uphill because
engine torque is restricted.
• When the accelerator pedal is deeply
depressed for a few seconds:
The system will be limited, judging
that the driver wants to speed up.
