What to do in an emergency
6
Use a towing cable or chain less
than 16 feet (5 m) long. Attach a
white or red cloth (about 12 inches
(30 cm) wide) in the middle of the
cable or chain for easy visibility.
Drive carefully so the towing cable
or chain remains tight during tow-
ing.
Before towing, check the dual
clutch transmission for fluid leaks
under your vehicle. If the dual
clutch transmission fluid is leaking,
flatbed equipment or a towing dolly
must be used.Accelerate or decelerate the vehi-
cle in a slow and gradual manner
while maintaining tension on the
tow rope or chain to start or drive
the vehicle, otherwise tow hooks
and the vehicle may be damaged.To avoid damage to your vehicle
and vehicle components when
towing:
Always pull straight ahead when
using the towing hooks. Do not
pull from the side or at a vertical
angle.
Do not use the towing hooks to
pull a vehicle out of mud, sand
or other conditions from which
the vehicle cannot be driven out
under its own power.
The vehicle should be towed at a
speed of 15 mph (25 km/h) or
less within the distance of 12
mph (20 km).

How to Disconnect the (-)
Cable for Regular Maintenance
(Hybrid vehicle)
When the vehicle is under regular
maintenance, make sure to separate
the (-) cable before maintenance.
Separate the (-) cable following the
below instructions.
1. Fold the rear left side seat.
2. Remove the service cover (A) on
the luggage trim.
3. Separate the (-) cable (B).
Reassemble in the reverse order.
Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windshield washer fluid
level.
Check for low or under-inflated
tires.
While operating your vehicle:
Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly
turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
Check the dual clutch transmission
P (Park) function.
Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal). Be careful when checking your
engine coolant/inverter coolant
level when the engine is hot.
This may result in coolant being
blown out of the opening and
cause serious burns and other
injuries.

if the vehicle is usually operated where
none of the following conditions apply.
If any of the following conditions apply,
you must follow the Maintenance
Under Severe Usage Conditions.

sandy areas.
Extensive use of brakes.
Driving in areas where salt or other
corrosive materials are used.
Driving on rough or muddy roads.

Driving for a prolonged period in
cold temperatures and/or extreme-
ly humid climates.
More than 50% driving in heavy
city traffic during hot weather
above 90°F (32°C).

Maintenance
Dual Clutch Transmission
Fluid
The dual clutch transmission fluid
should be inspected according to the
intervals specified in the mainte-
nance schedule.
Engine Clutch Actuator Fluid
The engine clutch actuator fluid level
should be inspected or replaced to
the intervals specified in the mainte-
nance schedule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake Fluid
Check the brake fluid level in the
brake the fluid reservoir. The level
should be between the MIN and the
MAX marks on the side of the reser-
voir. Use only hydraulic brake fluid
conforming to DOT 4 specification.
Parking Brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake Discs, Pads, Calipers
and Rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Exhaust Pipe and Muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the engine
and listen carefully for any exhaust
gas leakage. Tighten connections or
replace parts as necessary.
Suspension Mounting Bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering Gear Box, Linkage &
Boots / Lower Arm Ball Joint
With the vehicle stopped and the
engine off, check for excessive free-
play in the steering wheel. Check the
linkage for bends or damage. Check
the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts.
Drive Shafts and Boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air Conditioning Refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.

*1: Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econ-
omy by reducing the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure
in everyday driving, but in a year's time, they can offer significant cost and energy savings.
