The hill start assist system will not operate when
The hill start assist system will not operate when any of the following condi-
tions are met:
● Vehicles with an automatic transmission: The select lever is in a position
other than D or M (when facing uphill) or in a position other than R (when
facing downhill).
● Vehicles with a manual transmission: The shift lever is in R (when facing
uphill) or in a position other than R (when facing downhill).
● Vehicles with an automatic transmission: The accelerator pedal is
depressed.
● The parking brake is applied.
● Vehicles with a manual transmission: The clutch is engaged.
● Approximately 2 seconds have elapsed since the brake pedal was
released.
● The hill start assist ON indicator is not illuminated.
● Vehicles without a keyless access with push button start system: The
engine switch is turned to the “ACC” or “LOCK” position.
● Vehicles with a keyless access with push button start system: The push-
button ignition switch is turned to “ACC” mode or turned off.
■ Notes for the hill start assist system
● A slight jolt may be felt when starting off backward with the select lever in
R (vehicles with an automatic transmission) or the shift lever in R (vehi-
cles with a manual transmission) and then moving forward.
● If the braking power of the hill start assist system is insufficient, depress
the brake pedal.
● While the vehicle is stopped, make sure to depress the brake pedal.

WARNING
■Hill start assist system precautions
●Do not overly rely on the hill start assist system. The hill start assist system
may not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, the hill start assist system is not intended to hold
the vehicle stationary for an extended period of time. Do not attempt to use
the hill start assist system to hold the vehicle on an incline, as doing so
may lead to an accident.
● Do not stop the engine while the hill start assist system is operating, as the
hill start assist system will stop operating, possibly leading to an accident.

●Stop the vehicle in a safe place on a hard, flat surface.
● Set the parking brake.
● Shift the shift lever to N.
● Stop the engine.
■ Necessary tools
●TORX wrench (T30)
● Wrench, socket wrench and socket, or a similar tool (diameter

On initial delivery, the rear wing is adjusted to an angle at which both
stability at high speeds and enhan ced handling can be attained.
The rear wing can be adjusted
to 2 different angles.

CFRP (Carbon Fiber Reinforced Plastic) parts
● Due to the properties of the carbon fiber used in CFRP parts, the shade
and density of the carbon fiber weave may vary.
● Cleaning and protecting the CFRP parts: →P. 337, 338
WARNING
■After adjusting the angle of the rear wing
Make sure that the bolts and nuts are tightened securely. If they are not, the
rear wing may come off while driving, possibly leading to an accident.
CAUTION
■Handling of the rear wing
● Do not push or pull the rear wing with excessive force. Doing so may dam-
age the rear wing.
● When waxing the vehicle, be careful not to leave any residual wax
between the wing and wing end-plates.
■ When adjusting the angle of the rear wing
Observe the following precautions. Otherwise, the rear wing may be dam-
aged.
● Make sure to loosen the rear nuts and bolts before adjusting the angle of
the rear wing.

2-5. Driving information
Cargo and luggage
Capacity and distributionCargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) - (Total weight of occupants)
Steps for Determining Correct Load Limit 
(1)Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle's
placard.
(2)Determine the combined weight of the driver and passengers that will be riding in your vehicle.
(3)Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
(4)The resulting figure equals the available amount of cargo and lug- gage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will
be five 150 lb passengers in your vehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1400 - 750 (5 × 150) =
650 lbs.)
(5)Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the avail-
able cargo and luggage load capacity calculated in Step 4.
Take notice of the following information about storage precau-
tions, cargo capacity and load:
● Stow cargo and luggage in the trunk whenever possible.
● Be sure all items are secured in place.
● To maintain vehicle balance while driving, position luggage
evenly within the luggage compartment.
● For better fuel economy, do not carry unnecessary weight.
