Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
Engine missing, stumbling or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air
conditioning system after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon monox-
ide leak. Drive with the windows open and have the exhaust system
checked immediately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire
wear
Vehicle pulls to one side when driven straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.
CAUTION
If your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and

Maintenance and care
CT200h_OM_OM76067E_(EE)
Engine oil consumption
The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
A new engine consumes more oil.
When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level
accurately.
Oil consumption: Max. 1.0 L/1000 km (1.1 qt./600 miles, 0.9 lmp.qt./
600 miles)
If your vehicle consumes more than 1.0 L (1.1 qt., 0.9 lmp.qt.) every
1000 km (600 miles), contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
CAUTION
Used engine oil
Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation and skin cancer, so care should
be taken to avoid prolonged and repeated contact. To remove used engine
oil from your skin, wash thoroughly with soap and water.
Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground. Call any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional, service station or auto parts store for
information concerning recycling or disposal.
Do not leave used engine oil within the reach of children.

Checking interval
Inspect, clean and replace the air conditioning filter according to the mainte-
nance schedule. In dusty areas or areas with heavy traffic flow, early
replacement may be required. (For scheduled maintenance information,
please refer to the “Lexus Service Booklet” or “Lexus Warranty Booklet”.)
If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
NOTICE
To prevent damage to the system
When using the air conditioning system, make sure that a filter is always
installed.
When cleaning the filter, do not clean with water.

When trouble arises

If your vehicle needs to be towed
Before towing
The following may indicate a problem with your hybrid transmis-
sion. Contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional before towing.
The hybrid system is operating but the vehicle will not move.
The vehicle makes an abnormal sound.
If there is a malfunction in the P position control system, the smart
entry & start system or the immobilizer system, or if the 12-volt
battery is discharged, the vehicle cannot be towed with the front
wheels on the ground, as the front wheels may be locked. In this
case, transport the vehicle with both front wheels or all four wheels
lifted.
If towing is necessary, we recommend having your vehicle towed by
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional or a commercial towing service, using a lift-
type truck or flat bed truck.
Use a safety chain system for all towing, and abide by all state/provin-
cial and local laws.

6-1. Specifications
CT200h_OM_OM76067E_(EE)
Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which
allows cold startability. Oils with a lower value before the W allow
for easier starting of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil
when the oil is at high temperature. An oil with a higher viscosity
(one with a higher value) may be better suited if the vehicle is oper-
ated at high speeds, or under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil contain-
ers to help you select the oil you should use.
API Service Symbol
Top portion: The oil quality des-
ignation by API (American
Petroleum Institute) (SN)
Center portion: The SAE vis-
cosity grade (SAE 0W-20)
Lower portion:
“Resource-Conserving” means
that the oil has fuel saving and
environmental protection capa-
bilities.
ILSAC Certification Mark
The ILSAC (International
Lubricant Standardization and
Approval Committee) Certifica-
tion Mark is displayed on the
front of the container.
