Continuously variable trans-
missionThe continuously variable transmission is
electronically controlled and provides an
infinite number of forward speeds and 1
reverse speed. It also has a manual mode.
WARNING
Do not shift from the“P”or“N”
position into the“D”or“R”position
while depressing the accelerator
pedal. This may cause the vehicle
to jump forward or backward.
CAUTION
.Observe the following precau-
tions. Otherwise, the transmis-
sion could be damaged.
–Shift into the“P”or“R”posi-
tion only after the vehicle has
completely stopped.
–Do not shift from the“D”
position into the“R”position
or vice versa until the vehicle
has completely stopped.
.Do not race the engine for more
than 5 seconds in any position
except the“N”or“P”positionwhen the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.
.Never move the vehicle as fol-
lows. Doing so may result in an
unexpected accident or malfunc-
tion.
–Moving rearward by inertia
with the select lever set in a
forward driving position.
–Moving forward by inertia with
the select lever set in the“R”
position.
.When parking the vehicle, first
securely apply the parking brake
and then place the select lever in
the“P”position. Do not park for a
long time with the select lever in
any other position as doing so
could result in a dead battery.
NOTE.When the engine coolant tempera-
ture is still low, the transmission will
upshift to higher engine speeds than
when the coolant temperature is suffi-
ciently high in order to shorten the
warm-up time and improve driveability.
The gearshift timing will automaticallyshift to the normal timing after the
engine has warmed up.
.Immediately after transmission fluid
is replaced, you may feel that the
transmission operation is somewhat
unusual. This results from invalidation
of data which the on-board computer
has collected and stored in memory to
allow the transmission to shift at the
most appropriate times for the current
condition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.
.When driving under continuous hea-
vy load conditions such as when climb-
ing a long, steep hill, the engine speed
or the vehicle speed may automatically
be reduced. This is not a malfunction.
This phenomenon results from the
engine control function maintaining
the cooling performance of the vehicle.
The engine and vehicle speed will
return to a normal speed when the
engine is able to maintain the optimum
cooling performance after the heavy
load decreases. Take extremely care
when driving under a heavy load.
.The continuously variable transmis-
sion is a chain type system that pro-
vides superior transmission efficiency
for maximum fuel economy. At times,
depending on varying driving condi-
tions, a chain operating noise may be

Loading your vehicle
WARNING
.Never allow passengers to ride
on a folded rear seatback or in the
trunk. Doing so may result in
serious injury.
.Never stack luggage or other
cargo higher than the top of the
seatback because it could tumble
forward and injure passengers in
the event of a sudden stop or
accident. Keep luggage or cargo
low, as close to the floor as
possible.
.Stow cargo and luggage in the
trunk whenever possible..To prevent cargo and luggage
from sliding forward during brak-
ing, do not stack anything in the
enlarged trunk. Keep cargo and
luggage low, as close to the floor
as possible.
.When you carry something inside
the vehicle, secure it whenever
you can to prevent it from being
thrown around inside the vehicle
during sudden stops, sharp turns
or in an accident.
.Do not pile heavy loads on the
roof. These loads raise the vehi-
cle’s center of gravity and make it
more prone to tip over.
.Secure lengthy items properly to
prevent them from shooting for-
ward and causing serious injury
during a sudden stop.
.Never exceed the maximum load
limit. If you do, some parts on
your vehicle can break, or it can
change the way your vehicle
handles. This could result in loss
of control and cause personal
injury. Also, overloading can
shorten the life of your vehicle.
.Do not place cargo or luggage in
or on the following locations as
the item may get under theclutch, brake, or accelerator ped-
al and prevent the pedals from
being depressed properly, block
the driver’s vision, or hit the
driver or passengers, causing
an accident:
–At the feet of the driver
–On the front passenger or rear
seats (when stacking items)
–On the rear shelf
–On the instrument panel
–On the dashboard
CAUTION
Do not carry spray cans, containers
with flammable or corrosive liquids
or any other dangerous items inside
the vehicle.NOTEFor better fuel economy, do not carry
unneeded cargo.

&Precautions for TYPE RAThe roof carrier and other equipment
cannot be attached on the carbon roof
because of the design.
WARNING
Do not place a roof carrier or any
other equipment on the roof of the
vehicle. Due to the design of the
roof, the cargo may fall off and cause
an accident.&Roof molding and crossbar (if
equipped)
CAUTION
.For cargo carrying purposes, the
roof molding must be used to-
gether with a roof crossbar kit
and the appropriate carrying at-
tachment. Otherwise, damage tothe roof or paint or a dangerous
road hazard due to loss of cargo
could result.
.When using the roof crossbar kit,
make sure that the total weight of
the crossbars, carrying attach-
ment and cargo does not exceed
the maximum load limit. Over-
loading may cause damage to
the vehicle and create a safety
hazard.
Cargo can be carried after securing the
roof crossbar kit to the roof molding and
installing the appropriate carrying attach-
ment. When installing the roof crossbar kit,
follow the manufacturer’s instructions.
When carrying cargo on the roof using the
roof crossbar kit and carrying attachments,
never exceed the maximum load limit as
explained below. You should also be
careful that the vehicle does not exceed
the Gross Vehicle Weight Rating (GVWR)
and front and rear Gross Axle Weight
Rating (GAWR). For information about
loading cargo into or onto your vehicle,
refer to“Loading your vehicle”F8-11. The
maximum total load on the roof (including
