Before DrivingDriving PreparationCheck the following items before you start driving.
•Make sure there are no obstructions on the windows, door mirrors, exterior
lights, or other parts of the vehicle.
u Remove any frost, snow, or ice.
u Remove any snow on the roof, as this can slip down and obstruct your field of
vision while driving. If frozen solid, remove ice once it has softened.
u When removing ice from around the wheels, be sure not to damage the wheel
or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.
• Make sure the tires are in good condition.
u Check air pressures, and check for damage and excessive wear.
2 Checking and Maintaining Tires P. 456
•Make sure there are no people or objects behind or around the vehicle.
u There are blind spots from the inside.■
Exterior Checks
1Exterior ChecksNOTICEWhen doors are frozen shut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable materials left under the hood, causing a
fire. If you’ve parked your vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal.
Also check under the hood for leftover flammable
materials after you or someone else has performed
maintenance on your vehicle.

1 When Driving
When you set the power mode to ON, you may feel
as if the brake pedal is sinking down. This is normal.1Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and in
thinner air found at altitudes 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 defogger 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. If temperatures consistently
below -22°F (-30°C) are expected, the coolant
mixture should be changed to a higher concentration
to prevent freezing. Consult a dealer for details.
If 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.

Precautions While DrivingAvoid driving in deep water and on flooded roads. This can damage the engine,
driveline, or cause electrical component failure.■
In Rain
1Precautions While DrivingNOTICEDo not change the gear position while pressing the
accelerator pedal. You could damage the
transmission.NOTICEThe following can damage the under spoiler:•Parking the vehicle by a parking block•Parallel parking along the road shoulder•Driving toward the bottom of a hill•Driving up or down to a different surface level
(such as a road shoulder)•Driving on a rutted or bumpy road•Driving on a road with potholes.NOTICEIf you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel on
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 or VEHICLE
OFF (LOCK) while driving, the engine will shut down
and all steering and brake power assist functions will
stop, making it difficult to control the vehicle.
