WARNING
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution when driving
Do not turn the engine switch to the “LOCK” position while driving. If, in an
emergency, you must turn the engine off while the vehicle is moving, turn
the engine switch only to the “ACC” position to stop the engine. An accident
may result if the engine is stopped while driving. ( →P. 397)
NOTICE
■To prevent battery discharge
Do not leave the engine switch in the “ACC” or “ON” position for long peri-
ods of time without the engine running.
■ When starting the engine
● Do not crank the engine for more than 30 seconds at a time. This may
overheat the starter and wiring system.
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by your Toyota dealer immediately.

Maintenance and care
C-HR_OM_USA_OM10526U
■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle’s interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-
ing the carpet as dry as possible.
■ Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
WARNING
■Water in the vehicle
● Do not splash or spill liquid in the vehicle.
Doing so may cause electrical components, etc., to malfunction or catch
fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
(→P. 34)
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
■ Cleaning the interior (especially instrument panel)
Do not use a polish wax or polish cleaner. The instrument panel may reflect
off the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.

3806-3. Do-it-yourself maintenance
C-HR_OM_USA_OM10526U
■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. ( →P. 381)
● If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
■ When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload, non-genuine parts or parts not designed for this vehicle may be
unusable.
WARNING
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
● Never use a fuse of a higher amperage rating than that indicated, or use\
any other object in place of a fuse.
● Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
● Do not modify the fuses or fuse boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your
Toyota dealer as soon as possible.
