Engine Coolant Temperature
Gauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch or Engine Start/Stop
button is ON.
If the gauge pointer moves beyond
the normal range area toward the “H”
position, it indicates overheating that
may damage the engine.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to “If the Engine
Overheats” in chapter 6.
Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.OJF048134L
WARNING - Hot radiator
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pres-
sure and could cause severe
burns. Wait until the engine is
cool before adding coolant to
the reservoir.

Driving your vehicle
Before entering vehicle
• Be sure that all windows, outsidemirror(s), and outside lights are
clean.
Check the condition of the tires.
Check under the vehicle for any sign of leaks.
Be sure there are no obstacles behind you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil,
engine coolant, brake fluid, and
washer fluid should be checked on a
regular basis, at the exact interval
depending on the fluid. Further
details are provided in chapter 7,
“Maintenance”.
Before starting
Close and lock all doors.
Position the seat so that all con-trols are easily reached.
Buckle your seat belt.
Adjust the inside and outside rearview mirrors.
Be sure that all lights work.
Check all gauges.
Check the operation of warning lights when the ignition switch is
turned to the ON position.
Input any phone numbers or map locations (if vehicle equipped with
a navigation system) that you may
need during your trip.
Release the parking brake and make sure the brake warning light
goes out.
For safe operation, be sure you are
familiar with your vehicle and its
equipment.
BEFORE DRIVING
WARNING - Distracted driving
Focus on the road while driving.
The driver's primary responsi-
bility is in the safe and legal
operation of the vehicle. Use of
any handled devices, other
equipment or vehicle systems
that distract the driver should
not be used during vehicle
operation.

When ECO mode is activated:
The acceleration response may be
slightly reduced if 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 acti-
vated 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 the ECO indi-
cator.
When the coolant temperature is
low:
The system will be limited until
engine performance becomes nor-
mal.
When driving up a hill: The system will be limited to gain
power when driving uphill because
engine torque is restricted.
When driving the vehicle with the automatic transmission gear shift
lever in manual mode.
The system will be limited accord-
ing to the shift location.Drive mode (for Dual Clutch
Transmission)
SMART mode : SMART modeautomatically adjusts the driving
mode (COMFORT ↔ ECO ↔
SPORT) in accordance with the
driver's driving habits.
COMFORT mode : COMFORT mode provides smooth driving and
comfortable riding. When COM-
FORT mode is selected, it is not
displayed on the cluster.
SPORT mode : SPORT mode pro- vides sporty but firm riding.

Driving your vehicle
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
affected.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with
the off-road conditions where you
are going to drive before you begin
driving.
Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both the engine coolant
and engine oil.
Drive belt
A loose or damaged drive belt may
result in overheating of the engine.
WARNING- Under/overinflated tires
Always check the tires for proper
inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
For proper tire pressures, refer to
“Tires and wheels” in chapter 8.
WARNING- Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control. Worn-out tires
should be replaced as soon as
possible. For further information
and tread limits, refer to “Tires
and wheels” in chapter 7.
