4-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
● Use engine braking (shift position B instead of shift position D) to maintain
a safe speed when driving down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 250)
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, head or other parts of their body
are not outside the vehicle.
● AWD models: Do not drive the vehicle off-road.
This is not an AWD vehicle designed for off-road driving. Proceed with all
due caution if it becomes unavoidable to drive off-road.
● Do not drive across river crossings or through other bodies of water.
This may cause electric/electronic components to short circuit, damage
the hybrid system or cause other serious damage to the vehicle.
● Do not drive in excess of the speed limit. Even if the legal sp eed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicl e has high-
speed capability tires. Driving over 85 mph (140 km/h) may resu lt in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed capability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippa ge and
reduce your ability to control the vehicle.
● Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid, resulting in an accident.
● After driving through a puddle, depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the
brakes from functioning properly. If the brakes on only one sid e are wet
and not functioning properly, steering control may be affected.

4-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this could cause an accident or
fire due to hybrid system overheating. Additionally, if the veh icle is parked in
a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading to death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
● If the electronically controlled assist function does not operate, do not fol-
low other vehicles closely and avoid downhill or sharp turns th at require
braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
Have your brakes fixed immediately.
● The brake system consists of 2 or more individual hydraulic systems; if
one of the systems fails, the other(s) will still operate. In this case, the
brake pedal should be depressed more firmly than usual and the braking
distance will increase. Have your brakes fixed immediately.
■ If the vehicle becomes stuck (AWD models)
Do not spin the wheels excessively when any of the tires is up in the air, or
the vehicle is stuck in sand, mud, etc. This may damage the driveline com-
ponents or propel the vehicle forward or backward, causing an accident.

■When the ambient temperature is low, such as during winter driv ing con-
ditions
● When starting the hybrid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is until the “READY” indic ator is steady
on, as steady means the vehicle is able to move.
● When the hybrid battery (traction battery) is extremely cold (b elow approxi-
mately -22°F [-30°C]) under the influence of the outside temper ature, it may
not be possible to start the hybrid system. In this case, try t o start the hybrid
system again after the temperature of the hybrid battery increa ses due to
the outside temperature increase etc.

Driving
■Switching to EV drive mode whe n the gasoline engine is cold
If the hybrid system is started while the gasoline engine is cold, the gasoline
engine will start automatically after a short period of time in order to warm up.
In this case, you will become unable to switch to EV drive mode .
After the hybrid system has started and the “READY” indicator h as illumi-
nated, press the EV drive mode switch before the gasoline engin e starts to
switch to EV drive mode.
■ Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automati cally restart
in the following situations. When EV drive mode is canceled, a buzzer will
sound and the EV drive mode indicator will flash and go off.
● The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the energy monitor dis play is low.
( P. 128, 167)
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
When it is possible to inform the driver of automatic cancelation in advance, a
prior notice screen will appear on the multi-information displa y.
■ Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distance ranges from a few hun dred meters
to approximately 0.6 mile (1 km). However, depending on vehicle conditions,
there are situations when EV drive mode cannot be used. (The di stance that
is possible depends on the hybrid battery [traction battery] le vel and driving
conditions.)
■ Changing a driving mode when in EV drive mode
EV drive mode can be used in conjunction with Eco drive mode and power
mode.
However, EV drive mode may be automatically canceled when used in con-
junction with power mode.
■ Fuel economy
The hybrid system is designed to achieve the best possible fuel economy
during normal driving (using the gasoline engine and electric m otor [traction
motor]). Driving in EV drive mode more than necessary may lower fuel econ-
omy.
