Quick Reference Guide
SPORT HYBRID i-MMD SYSTEM MAIN COMPONENTS
Gasoline Engine– Runs the generator and under certain
conditions, drives the wheels directly.
Generator– Starts the engine and generates electric power
when driven by the gasoline engine to supply electricity to
power the electric motor and/or to charge the High Voltage
battery.
Electric Motor– Provides propulsion to drive the wheels in
conjunction with the gasoline engine in certain conditions and
provides electricity to the High Voltage battery through
regenerative braking.
High Voltage Battery– Provides electrical storage and serves
as a power source for the electric motor.
Learning about the High Voltage battery’s characteristics will
help you get the best handling and maximize the range of your
electric vehicle. (P491)
●Sounds Unique to the SPORT HYBRID i-MMD System
When you first start driving this vehicle, you will likely hear some unfamiliar sounds, particularly when you turn on the power system, or
while you are driving or accelerating from a stop. Some of these sounds are unique to this vehicle‘s powertrain, fuel, and clim ate control
systems; others are similar to sounds generate d by conventional automobiles that typically are masked by louder noises absent f rom 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 t o detect any
new or unusual 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.

Driving
Before Driving
Driving Preparation
Check 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.
2Checking and Maintaining Tires P. 631
•Make sure there are no people or ob jects behind or around the vehicle.
u There are blind spots from the inside.
■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.

Driving
Towing a Trailer
Towing Preparation
Your vehicle can tow a trailer if you carefully observe the load limits, use the proper
equipment, and follow the towing guidelin es. Check the load limits before driving.
■Total trailer weight
Maximum allowable weight of the trailer,
cargo, and everything in or on it must not
exceed 1,000 lbs (450 kg). Towing loads in
excess of this can seriously affect vehicle
handling and performance and can damage
the engine and drivetrain.
■Tongue load
The weight of the tongue with a fully loaded
trailer on the hitch should be approximately
10% of the total trailer weight.
• Excessive tongue load reduces front tire
traction and steering control. Too little
tongue load can make the trailer unstable
and cause it to sway.
• To achieve a proper tongue load, start by
loading 60% of the load toward the front
of the trailer and 40% toward the rear.
Readjust the lo ad as needed.
■Towing Load Limits1Towing Load Limits
Check if all loads are within limits at a public scale.
If a public scale is not av ailable, add the estimated
weight of your cargo load to the weight of your
trailer (as quoted by th e manufacturer), and the
tongue load.
Break-in Period.
Avoid towing a trailer duri ng your vehicle's first 600
miles (1,000 km).
Never exceed the gross weight ratings.
Gross weight information 2 Specifications P. 694
3WARNING
Exceeding any load limit or improperly
loading your vehicle and trailer can cause a
crash in which you can be seriously hurt or
killed.
Check the loading of your vehicle and
trailer carefully before starting to drive.

Keep your foot firmly on the brake pedal when
turning the power system on.
The engine is harder to st art in cold weather and in
thinner air found at altit udes above 8,000 feet (2,400
meters).
When turning the power system on 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. Consult a dealer for details.
If the 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.
