4-2. Maintenance
CT200h_EE (OM76041E)
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
possible serious injury or death.
Handling of the 12-volt battery
12-volt battery posts, terminals and related accessories contain lead and lead
compounds which are known to cause brain damage. Wash your hands after
handling. (P. 496)

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.
