Maintenance
For winter tires:
• Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:
• Install them on the front tires only.
• Because your vehicle has limited tire clearance, we strongly recommend using the
chains listed below:
*1: On 245/30ZR20 tires, you cannot install any type of tire chains. If you have to use
tire chains, replace the original tires with the 235/40R18 tires.
• Follow the chain manufacturer’s instruction when installing. Mount them as
tightly as you can.
• Check that the chains do not to uch the brake lines or suspension.
• Drive slowly.

uuChecking and Maintaining Tires uCold Weather Driving
Maintenance
Cold Weather Driving
Summer Only tires and High Grip tires*1 or Ultra High Performance (UHP) tires*2 are
very sensitive to ambient temperatures and are designed to be used at temperatures
above 45°F (7°C). If the vehicle is operat ed with Summer Only tires or UHP tires at
temperatures below 45°F (7°C), the tires will provide decreasing amounts of grip
and other performance attributes. If the vehi cle is operated with Summer Only tires
or UHP tires at temperatures below 20°F (–7°C)
*1 or –4°F (–20°C)*2, the tire tread
may lose their elasticity and become brittl e, resulting in permanent damage to the
tread. A damaged tire may fail during use. Therefore, if you operate the vehicle
when ambient temperatures are below 45°F (7°C), we recommend that you install
other tires (e.g., mud+snow, winter) that are designed to provide appropriate
performance attributes under the anticipated conditions.

3WARNING
Use of Summer Only tires or Ultra High
Performance tires at temperatures below
45°F (7°C) may lead to a loss of
performance and control, which could
result in a crash, se rious injury or death.

Checking the Battery
The condition of the battery is monitored by a
sensor located on the negative terminal of the
battery. If there is a problem with this sensor,
the driver information in terface will display a
warning message. If this happens, have your
vehicle inspected by a dealer.
Check the battery terminals for corrosion
monthly.
If your vehicle’s battery is disconnected or goes dead:
• The audio system is disabled.
2 Reactivating the audio system P. 229
•The clock resets.
2 Adjusting the Clock P. 144
•
The immobilizer system needs to be reset.

Maintenance
Charging the Battery
Disconnect both battery cables to prevent damaging your vehicle’s electrical system.
Always disconnect the negative (–) cable first, and reconnect it last.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.
1 Battery
When you find corrosion, cl ean the battery terminals
by applying a baking powder and water solution.
Clean the terminals with a damp towel. Cloth/towel
dry the battery. Coat the terminals with grease to
help prevent future corrosion.
When replacing the battery, the replacement must be
of the same specifications.
Consult a dealer for more information.

Maintenance
Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, th e Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant sy stem only be serviced by trained and
certified technicians.
Never repair or replace the air conditioning evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.
Dust and Pollen Filter
The climate control system is equipped wi th a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance MinderTM messages will let
you know when to replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1Climate Control System Maintenance
NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one re moved from a used or
salvaged vehicle.
Refrigerant in your vehicle’ s air conditioning system is
flammable and can be igni ted during servicing if
proper procedures are not followed.
The air conditioner labe l is found under the hood:

■Cleaning Seat Belts
1Interior Care
Do not spill liquids inside the vehicle. Electrical
devices and systems may ma lfunction if liquids are
splashed on them.
Do not use silicone based sp rays on electrical devices
such as audio devices and switches. Doing so may
cause the items to malfunction or cause a fire inside
the vehicle.
If a silicone based spray is inadvertently used on
electrical devices, consult a dealer.
Depending on their compos ition, chemicals and
liquid aromatics may cause discoloration, wrinkles,
and cracking to resin-ba sed parts and textiles.
Do not use alkali solvents or organic solvents such as
benzene or gasoline.
After using chemicals, make su re to gently wipe them
away using a dry cloth.
Do not place used cloths on top of resin based parts
or textiles for long periods of time without washing.
