Quick Reference Guide
Energy Efficiency
As with a gasoline powered vehicle, the fuel efficiency and the range of this vehicle is most impacted by the driver’s driving style. Aggressive
acceleration and high-speed driving can easily trigger the system to switch the propulsion source to the gasoline-powered engin e. Climate
control system usage also has a strong impact with heavy usage ne gatively affecting the vehicle’s range. In particular, when it is cold
outside, climate control system consumes a lot of power, so th e vehicle’s driving range on electric power can be reduced. The c apacity of the
HV battery will be less when the temperature is low.
Battery Type
There are two types of batteries used in this vehicle, a standa rd 12-volt battery that powers the airbags, the interior and exterior lights, and
other standard 12-volt systems, and a high voltage battery that is used to power the propulsion motor and recharge the 12-volt battery.
Hybrid Vehicles
High voltage parts and high voltag e wires in this vehicle are sheathed in electromagnetic shielding material; therefore, the am ount of
electromagnetic waves emitted is no more gr eater than those emitted by household appliances or the electrical parts in conventional
vehicles.
Sounds Unique to the SP ORT HYBRID i-MMD Plug-in (intelligent Multi-Mode
Drive Plug-in)
When you first start driving this vehicle, you likely will hear some unfamiliar sounds, particularly when you first turn on the power system,
while driving, and just after parking. Some of these sounds are unique to this vehicle‘s powertrain, fuel, and climate control systems; others
are similar to sounds generated by conventional automobiles that typically are masked by louder noises absent from a vehicle of this design.
These sounds are not a cause for concern, and you will soon recognize them as normal and thus be able to detect any new or unus ual noise
should one develop.
After shutting off the engi ne, you may hear certain noises coming from the vehicle. Here’s the lowdown:
●Noise from Under Vehicle: This noise is caused by the vacuum pump inside the fuel evaporation leakage check module (ELCM).
Depending on conditions, the pump will come on for about 15 minutes about 5 to 10 hours after engine shutoff. This noise is just normal
vehicle operation and doesn’t indicate a vehicle problem.

Before Driving
Driving Preparation
Check the following items before you start driving.
• Make sure there are no obstructions on th e 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 wheel s, 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.
2Checking and Maintaining Tires P. 505
•Make sure there are no people or ob jects behind or around the vehicle.
u There are blind spots from the inside.
• Disconnect the charging cable.
■Exterior Checks1Exterior Checks
NOTICE
When doors are frozen s hut, 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 material s left under the hood, causing a
fire. If you’ve parked y our 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.
