CAUTION
General precautions while driving
Driving under the influence: Never drive your vehicle when under the
influence of alcohol or drugs that have impaired your ability to operate
your vehicle. Alcohol and certain drugs delay reaction time, impair judg-
ment and reduce coordination, which could lead to an accident that could
result in death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that
other drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone
or reading can result in a collision with resulting death or serious injury to
you, your occupants or others.
General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows, the moon roof, or other features of the vehicle. In addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal
to children.
Your vehicle contains batteries and/or accumulators. Do not discard them
into the environment but cooperate with separate collection
(Directive 2006/66/EC).

Hybrid system precautions
Take care when handling the hybrid system, as it contains a high
voltage system (about 650 V at maximum) as well as parts that
become extremely hot when the hybrid system is operating. Obey
the caution labels attached to the vehicle.

Driving assist systems
ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied sud-
denly, or if the brakes are applied while driving on a slippery
road surface
Brake assist
Generates an increased level of braking force after the brake
pedal is depressed when the system detects a panic stop situation
VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery
roads
VGRS (Variable Gear Ratio Steering) (if equipped)
Adjusts the front wheel turning angle in accordance with the
vehicle speed and steering wheel movement
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving situa-
tions. Be aware, however, that these systems are supplementary
and should not be relied upon too heavily when operating the vehi-
cle.
