C-HR_HEV_OM_Europe_OM10764E
■Tire information
● Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi)
greater than the recommended value when towing. ( P. 774)
● Increase the air pressure of the trailer tires in accordance with the total
trailer weight and according to the values recommended by the m anufac-
turer of your trailer.
■ Trailer lights
Please consult at any authorized retailer or Toyota authorized repairer, or any
reliable repairer when installing trailer lights, as incorrect installation may
cause damage to the vehicle’s lights. Please take care to compl y with your
state’s laws when installing trailer lights.
■ Break-in schedule
Toyota recommends that vehicles fitted with new power train com ponents
should not be used for towing trailers for the first 800 km (50 0 miles).
■ Safety checks before towing
● Check that the maximum load limit for the towing hitch/bracket and hitch ball
is not exceeded. Bear in mind that the coupling weight of the t railer will add
to the load exerted on the vehicle. Also make sure that the tot al load exerted
on the vehicle is within the range of the weight limits. ( P. 295)
● Ensure that the trailer load is secure.
● Supplementary outside rear view mirrors should be added to the vehicle if
the traffic behind cannot be clearly seen with standard mirrors . Adjust the
extending arms of these mirrors on both sides of the vehicle so that they
always provide maximum visibility of the road behind.
■ Maintenance
● Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight burden placed on the vehicle c ompared to
normal driving.
● Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).

GPF (Gasoline Par ticulate Filter) system
■If “Exhaust filter full. See owner’s manual.” is shown on the multi-infor-
mation display
● The message may be displayed while high load driving with particulate mat-
ter accumulating.
● Hybrid system output (engine speed) is restricted when a certain amount of
particulate matter accumulates, however, it is possible to driv e the vehicle
unless the malfunction indicator lamp comes on.
● Particulate matter can accumulate more quickly if the vehicle is frequently
driven short trips or at low s peeds, or if the hybrid system is regularly started
in an extremely cold environment. Excessive accumulation of par ticulate
matter can be prevented by periodically driving long distances continuously
with intermittent releasing of the accelerator pedal, such as w hen driving on
highways and freeways.
■ If the malfunction indicator lamp comes on or “Engine Maintenance
Required. Visit Your Dealer.” is shown on the multi-information display
The amount of accumulated particulate matter has exceeded a cer tain level.
Have the vehicle inspected by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reli able repairer immediately.
The GPF system collects particulate matter in the exhaust gas
by using an exhaust gas filter.
The system will operate to regenerate the filter automatically,
depending on the vehicle conditions.
NOTICE
■ To prevent the GPF system from not operating properly
● Do not use fuel other than the specified type
● Do not modify the exhaust pipes

Cleaning and protecting the vehicle exterior
●Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any di rt
and dust.
● Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
● For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
● Wipe away any water.
● Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
■ Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface
scratches caused in a car wash, etc.
● The coating lasts for 5 to 8 years from when the vehicle is delivered from the
plant.
● The restoration time differs depending on the depth of the scratch and out-
side temperature.
The restoration time may become shorter when the coating is war med by
applying warm water.
● Deep scratches caused by keys, coins, etc., cannot be restored.
● Do not use wax that contain abrasives.
Perform the following to protect the vehicle and maintain it in
prime condition:

■ Automatic car washes
● Fold the mirrors before washing the vehicle. Start washing from the front of
the vehicle. Make sure to extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle surface,
parts (wheel, etc.) and harm your vehicle’s paint.
● Rear spoiler may not be washable in some automatic car washes. There
may also be an increased risk of damage to vehicle.
■ High pressure car washes
As water may enter the cabin, do not bring the nozzle tip near the gaps
around the doors or perimeter of the windows, or spray these ar eas continu-
ously.
■ Note for a smart entry & start system
If the door handle becomes wet while the electronic key is with in the effective
range, the door may lock and unlock repeatedly. In that case, f ollow the fol-
lowing correction procedures to wash the vehicle:
● Place the key in a position 2 m (6 ft.) or more separate from the vehicle
while the vehicle is being washed. (Take care to ensure that th e key is not
stolen.)
● Set the electronic key to battery-saving mode to disable the smart entry &
start system. ( P. 207)
■ Wheels and wheel ornaments (vehicles without matte black painted
wheels)
● Remove any dirt immediately by using a neutral detergent.
● Wash detergent off with water immediately after use.
● To protect the paint from damage, make sure to observe the following pre-
cautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driv-
ing or parking in hot weather

■ Aluminum wheels (vehicles with matte black painted wheels)
As matte black painted wheels require different cleaning method s than con-
ventional aluminum wheels, be sure to observe the following. Fo r details,
consult any authorized Toyota retailer or Toyota authorized rep airer, or any
reliable repairer.
● Remove dirt using water. If the wheels are excessively dirty, use a sponge
or soft cloth dampened with a diluted neutral detergent to remo ve the dirt.
● When using detergent, make sure to rinse it off with water immediately.
Then use a soft cloth to wipe off the water.
● To prevent the matte black paint from being damaged, make sure to observe
the following precautions:
• Do not scrub or polish the wheels using a brush or dry cloth.
• Do not use any wheel coatings or abrasive detergents.
• When using an automatic car wash, disable/do not select the wh eel
brush function (if such an option is available).
■ Brake pads and calipers
Rust may form if the vehicle is parked with wet brake pads or d isc rotors,
causing them to stick. Before parking the vehicle after it is w ashed, drive
slowly and apply the brakes several times to dry the parts.
■ Bumpers and side moldings
Do not scrub with abrasive cleaners.
■ Plated portions (if equipped)
If dirt cannot be removed, clean the parts as follows:
● Use a soft cloth dampened with an approximately 5% solution of neutral
detergent and water to clean the dirt off.
● Wipe the surface with a dry, soft cloth to remove any remaining moisture.
● To remove oily deposits, use alcohol wet wipes or a similar product.

WARNING
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doi ng so may
cause the electrical components, etc., to catch fire.
■ When cleaning the windshield
● When a wet rag or similar is held close to the raindrop sensor
● If something bumps against the windshield
● If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
■ Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the exhaust p ipe until it
has cooled sufficiently, as touching a hot exhaust pipe can cau se burns.
■ Precaution regarding the rear bumper with Blind Spot Monitor (if
equipped)
If the paint of the rear bumper is chipped or scratched, the sy stem may mal-
function. If this occurs, consult any authorized Toyota retaile r or Toyota
authorized repairer, or any reliable repairer.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in
hands being caught or other serious inju-
ries and cause damage to the wiper
blades.
● When the upper part of the windshield
where the raindrop sensor is located is
touched by hand
