When you select the Sport Sharp (S#)
mode with the select lever in the“D”
position, the transmission gear ratio will
shift from variable speed to eight-speed.
The select lever/gear position indicator
display will change from“D”to the gear
position.
When selecting Sport Sharp (S#) mode,
the following controls will be applied.
.Uphill control
Prevents unnecessary shift-up/shift-down
during ascent.
.Cornering control
While turning, if there is a large centrifugal
force, shift-up will not occur: during re-
acceleration.
.Braking control
At the beginning of corners etc., heavy
application of the brake pedal will cause
automatic downshift and gently re-accel-
erate.
.Sudden acceleration return control
During acceleration, if acceleration pedal
is returned suddenly (for example, at
corners etc.), shift-up will not be applied.

conditions than a two wheel drive vehicle.
There is little difference in handling, how-
ever, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure to
reduce your speed and maintain an ample
distance from other vehicles.
.Always check the cold tire pressure
before starting to drive. The recommended
tire pressure is provided on the tire
placard, which is located under the door
latch on the driver’s side.
.Frequent driving of an AWD vehicle
under hard-driving conditions such as
steep hills or dusty roads will necessitate
more frequent replacement of the follow-
ing items than that specified in the“War-
ranty and Maintenance Booklet”.
–Engine oil
–Brake fluid
–Rear differential gear oil
–Manual transmission oil (MT mod-
els)
–Continuously variable transmission
fluid (CVT models)
–Front differential gear oil (CVT
models)
.There are some precautions that you
must observe when towing your vehicle.
For detailed information, refer to“Towing”
F9-21.
Driving precautionWater entering the engine air intake or the
exhaust pipe or water splashing onto
electrical parts may damage your vehicle
and may cause it to stall. Never attempt to
drive through rushing water; regardless of
its depth, it can wash away the ground
from under your tires, resulting in possible
loss of traction and even vehicle rollover.
Winter driving&Operation during cold weath-
erCarry some emergency equipment, such
as a window scraper, a bag of sand, flares,
a small shovel and jumper cables.
Check the battery and cables. Cold tem-
peratures reduce battery capacity. The
battery must be in good condition to
provide enough power for cold winter
starts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
Keep the door locks from freezing by
squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the rubber weather strips
around the door. If the door is frozen, use
hot water to melt the ice, and afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.

tion, brand and load range and you should
never mix radial, belted bias or bias tires
since this may result in dangerous hand-
ling characteristics. When you choose a
tire, make sure that there is enough
clearance between the tire and vehicle
body.
Remember to drive with care at all times
regardless of the type of tires on your
vehicle.&Tire chains
CAUTION
You cannot use tire chains on your
vehicle because of the lack of clear-
ance between the tires and vehicle
body.NOTEEven though you cannot use tire
chains, use of another type of traction
device (such as spring chains) may be
acceptable if use on your vehicle is
recommended by the device manufac-
turer, taking into account tire size and
road conditions. Follow the device
manufacturer’s instructions, especially
regarding maximum vehicle speed.
To help avoid damage to your vehicle,drive slowly, readjust or remove the
device if it is contacting your vehicle,
and do not spin your wheels. Damage
caused to your vehicle by use of a
traction device is not covered under
warranty.
Make certain that any traction device
you use is an SAE class S device, and
use it on the front wheels only. Always
use the utmost care when driving with a
traction device. Overconfidence be-
cause you are using a traction device
could easily lead to a serious accident.
&Rocking the vehicleIf you must rock the vehicle to free it from
snow, sand, or mud, depress the accel-
erator pedal slightly and move the shift
lever/select lever back and forth between
“1”/“D”and“R”repeatedly. Do not race the
engine. For the best possible traction,
avoid spinning the wheels when trying to
free the vehicle.
When the road surface is extremely
slippery, you can obtain better traction by
starting the vehicle with the transmission in
2nd than in 1st (MT models and CVT
models).
If your vehicle is a CVT model, for
information about holding the transmissionin the 2nd position, refer to“Selection of
manual mode”F7-25.

&Towing with all wheels on the
ground1. Release the parking brake and put the
transmission in the“N”/neutral position.
2. The ignition switch should be in the
“ON”position while the vehicle is being
towed.
3. Take up slack in the towline slowly to
prevent damage to the vehicle.
WARNING
.Never turn the ignition switch to
the“LOCK”/“OFF”position while
the vehicle is being towed be-
cause the steering wheel and the
direction of the wheels will be
locked..Remember that the brake booster
and power steering do not func-
tion when the engine is not run-
ning. Because the engine is
turned off, it will take greater
effort to operate the brake pedal
and steering wheel.
CAUTION
.If transmission failure occurs,
transport your vehicle on a flat-
bed truck.
.For CVT models, the traveling
speed must be limited to less
than 20 mph (32 km/h) and the
traveling distance to less than 31
miles (50 km). For greater speeds
and distances, transport your
vehicle on a flat-bed truck.
