What to do in an emergency
6
Use a towing cable or chain lessthan 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.
OAE066025
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.
Limit the vehicle speed to 10
mph (15 km/h) and drive less
than 1 mile (1.5 km) when tow-
ing to avoid serious damage
to the dual clutch transmis-
sion.

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) onthe 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 ofthe 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.

that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
At least twice a year: (i.e., every Spring and Fall)
Check radiator, heater and air con-
ditioning hoses for leaks or dam-
age.
Check windshield washer spray and wiper operation. Clean wiper
blades with a clean cloth damp-
ened with washer fluid.
Check headlamp alignment.
Check muffler, exhaust pipes, shields and clamps.
Check the seat belts for wear and function.
At least once a year:
Clean body and door drain holes.
Lubricate door hinges and hoodhinges.
Lubricate door and hood locks and latches.
Lubricate door rubber weather strips.
Lubricate door checker.
Check the air conditioning system.
Inspect and lubricate transmission linkage and controls.
Clean the battery and terminals.
Check the brake fluid level. Follow Normal Maintenance Schedule
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.
Repeated short distance driving.
Driving in dusty conditions or
sandy areas.
Extensive use of brakes.
Driving in areas where salt or other corrosive materials are used.
Driving on rough or muddy roads.
Driving in mountainous areas.
Extended periods of idling or low speed operation.
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 3 or DOT 4 spec-
ification.
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.

3: If the ACEA C2 engine oil is not available in your country, you are able to use ILSAC GF-3 (or above) or ACEA A3 (or above).
