information.
Wheel size designation
Wheels are also marked with important
information that you need if you ever have to replace one. The following ex‐
plains what the letters and numbers in
the wheel size designation mean. Example wheel size designation:
7.5JX19
7.5 - Rim width in inches.
J - Rim contour designation.
19 - Rim diameter in inches.
Tire speed ratings
The chart below lists many of the dif‐ ferent speed ratings currently being
used for passenger car tires. The speed
rating is part of the tire size designa‐ tion on the sidewall of the tire. This
symbol corresponds to that tire's de‐
signed maximum safe operating speed.
SpeedRatingSymbolMaximum Speed
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph)
SpeedRatingSymbolMaximum Speed
Z Above 240 km/h (149

3. Checking tire life (TIN: Tire
Identification Number)
Any tires that are over 6 years old,
based on the manufacturing date, (in‐ cluding the spare tire) should be re‐
placed by new ones. You can find the
manufacturing date on the tire sidewall (possibly on the inside of the wheel),
displaying the DOT Code. The DOT Code
is a series of numbers on a tire consist‐ ing of numbers and English letters. The
manufacturing date is designated by
the last four digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and tread
pattern and the last four numbers indi‐ cate week and year manufactured.
For example:
DOT XXXX XXXX 1616 represents that
the tire was produced in the 16th week
of 2016.
WARNING
nTire age
Tires degrade over time, even whenthey are not being used.Regardless of the remaining tread,we recommend that tires be re‐placed after approximately six (6)years of normal service. Heat causedby hot climates or frequent highloading conditions can accelerate theaging process. Failure to follow thiswarning can result in sudden tirefailure, which could lead to a loss ofcontrol and an accident involving se‐rious injury or death.
4. Tire ply composition and material
The number of layers or plies of rub‐
ber-coated fabric in the tire. Tire man‐ ufacturers also must indicate the ma‐
terials in the tire, which include steel,
nylon, polyester, and others. The letter "R" means radial ply construction; the
letter "D" means diagonal or bias ply
construction; and the letter "B" means belted-bias ply construction.

APPEARANCE CARE
Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical cleaner or polish. Read all warning and
caution statements that appear on the
label.
Finish maintenance
Washing
To help protect your vehicle’s finish
from rust and deterioration, wash it thoroughly and frequently at least once
a month with lukewarm or cold water.
If you use your vehicle for off-road
driving, you should wash it after each off-road trip. Pay special attention to
the removal of any accumulation of
salt, dirt, mud, and other foreign mate‐ rials. Make sure the drain holes in the
lower edges of the doors and rocker
panels are kept clear and clean.
Insects, tar, tree sap, bird droppings, in‐ dustrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used. After washing, rinse the vehicle thor‐
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
CAUTION
•Do not use strong soap, chemicaldetergents or hot water, and donot wash the vehicle in direct sun‐light or when the body of the vehi‐cle is warm.
•Be careful when washing the sidewindows of your vehicle.Especially, with high-pressure wa‐ter, water may leak through thewindows and wet the interior.
•To prevent damage to the plasticparts and lamps, do not clean withchemical solvents or strong deter‐gents.
WARNING
nWet brakes
After washing the vehicle, test thebrakes while driving slowly to see if

they have been affected by water. Ifbraking performance is impaired, drythe brakes by applying them lightlywhile maintaining a slow forwardspeed.
High-pressure washing
• When using high-pressure washers, make sure to maintain sufficient dis‐
tance from the vehicle.
Insufficient clearance or excessive pressure can lead to component
damage or water penetration.
• Do not spray the camera, sensors or its surrounding area directly with a
high pressure washer. Shock applied
from high pressure water may cause the device to not operate normally.
• Do not bring the nozzle tip close to boots (rubber or plastic covers) or
connectors as they may be damaged
if they come into contact with high
pressure water.

Maintenance

Recommended SAE viscosity number
CAUTION
Always be sure to clean the area around any filler plug, drain plug, or dipstick before checking or draining any lubricant.This is especially important in dusty or sandy areas and when the vehicle is used on unpaved roads. Cleaning the plug anddipstick areas will prevent dirt and grit from entering the engine and other mechanisms that could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather operating (engine start and engine oil flowabil‐
ity). Lower viscosity engine oils can provide better fuel economy and cold weather performance, however, higher viscosity en‐ gine oils are required for satisfactory lubrication in hot weather.
Using oils of any viscosity other than those recommended could result in engine damage. When choosing an oil, consider the
range of temperature your vehicle will be operated in before the next oil change. Proceed to select the recommended oil vis‐ cosity from the chart.

*1 : For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE 5W-30 (ACEA A5). However, if
the engine oil is not available in your country, select the proper engine oil using the engine oil viscosity chart.
