1Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to st art in cold weather and in
thinner air found at altit udes above 8,000 feet (2,400
meters).
When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate
control system and rear de fogger in order to reduce
battery drain.
If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. Cons ult a dealer for details.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
The immobilizer system pr otects your vehicle from

uuWhen Driving uPrecautions While Driving
Driving
Precautions While Driving
Avoid driving in deep water and on flooded roads. This can damage the engine or
driveline, or cause electrical component failure.
If there is a strong impact with something under the vehicle, stop in a safe location.
Check the underside of the vehicle for damage or any fluid leaks.
■In Rain
■Other Precautions
1 Precautions While Driving
NOTICE
Do not change the transmission while pressing the
accelerator pedal. You could damage the
transmission.
NOTICE
If you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel in
the full left or right position for a while, the electric
power steering (EPS) system heats up. The system
goes into a protective mode, and limits its
performance. The steering wheel becomes harder
and harder to operate. Once the system cools down,
the EPS system is restored.
Repeated operation under these conditions can
eventually damage the system.
If the power mode is set to ACCESSORY while
driving, the engine will shut down and all steering
and brake power assist functi ons will stop, making it
difficult to control the vehicle.
Do not select
( N while driving as you will lose engine
braking (and accelera tion) performance.
During the first 600 miles (1,000 km) of operation,
avoid sudden acceleration or full throttle operation so
as not to damage the engine or powertrain.
Avoid hard braking for the first 200 miles (300 km).
You should also follow this when the brake pads are
replaced.

■If you want to keep the transmission in (N position [car wash mode]
With the engine running:
1. Press and hold the brake pedal.
2. Select
(N, then release the button to display (N (Neutral) hold mode on the driver
information interface.
3. Press and hold
(N again for two seconds.
u This puts the vehicle in car wash mode which must be used when your vehicle
is pulled through a conveyor type automatic car wash where you or an
attendant do not remain in the vehicle.
If the ENGINE STOP/START button is pressed
after car wash mode has been activated, the
power mode will change to ACCESSORY and
a message will be displayed on the driver
information interface. u For 15 minutes the transmission remains
in
(N with the power mode in
ACCESSORY. After that, the
transmission automatically changes to
(P and the power mode changes to OFF.
u Manually changing to
(P cancels
ACCESSORY mode. The
(P indicator
comes on and the power mode changes
to OFF. You must always put the
transmission into
(P when car wash
mode is no longer needed.

uuWhen Driving uShifting
Continued
Driving
Use the paddle shifters to change betw een 1st and 10th gears without removing
your hands from the steering wheel. The trans mission will switch to the sequential
mode.
■When the transmi ssion is in (D:
The vehicle will go into the sequential m ode momentarily, and the gear selection
indicator will come on.
When the vehicle goes into the sequential mode by
(- paddle shifter and the lower
gear is available, the tran smission properly selects single or double gear change.
Once you start traveling at a constant speed , the sequential mode will automatically
switch off, and the gear sele ction indicator will go off.
Hold the
(+ paddle shifter for two seconds to return to normal drive.
■When the transmi ssion is in (D with SPORT mode:
The vehicle will go into th e sequential mode, and the M (sequential mode) indicator
and gear selection indicator will come on.
If the vehicle speed increases and the engi ne speed reaches near the tachometer’s
red zone, the transmission automatically shifts up to the next gear.
You can cancel this mode by holding the
(+ paddle shifter for two seconds. When
the sequential mode is canceled, the sequential mode indicator and gear selection
indicator go off.

uuWhen Driving uShifting
Driving
Use the paddle shifters to change between 1st and 7th speeds without releasing
your hands from the steering wheel. The transmission switches to the 7-speed
manual shift mode when you pull a paddle shifter while driving. This mode is useful
when engine braking is needed.
■When the transmi ssion is in (D:
The shift mode goes into the 7-speed ma nual shift mode temporarily, and the
number is displayed in the gear selection indicator.
The 7-speed manual shift mode is canceled automatically if you drive at constant
speed or accelerate, and the number in the gear selection indicator goes off.
You can cancel this mode by pulling the
(+ paddle shifter for a few seconds.
The 7-speed manual shift mode is especial ly useful when reducing the vehicle speed
temporarily before making a turn.
■When the transmi ssion is in (D with SPORT mode:
The shift mode goes into the 7-speed manual shift mode. The M indicator and the
speed number are displayed in the gear selection indicator. As the vehicle speed
slows down, the transmission automaticall y shifts down accordingly. When the
vehicle comes to a stop, it automatically shifts down into 1st.
If the vehicle speed increases and the engi ne speed reaches near the tachometer’s
red zone, the transmission automatically shifts up.
You can only pull away in 1st speed.
When canceling the 7-speed manual shift mode, pressing the SPORT button. When
the 7-speed manual shift mode is canceled, the M indicator and gear selection
indicator go off.
■7-Speed Manual Shift Mode1 7-Speed Manual Shift Mode
In the 7-speed manual shif t mode, the transmission
shifts up or down by opera ting either paddle shifter
under the following conditions:
Shift Up: The engine sp eed reaches the lowest
threshold of the higher speed position.
Shift Down: The engine sp eed reaches the highest
threshold of the lower speed position.
When the engine speed reaches near the
tachometer’s red zone, the transmission shifts up
automatically.
When the engine speed reaches the lowest threshold
of the selected speed positi on, the transmission shifts
down automatically.
Operating the paddle shifte rs on slippery surfaces
may cause the tires to lock up. In this case, the 7-
speed manual shift mode is canceled and goes back
to the normal
( D driving mode.
