RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only
lubricants of the proper quality. The correct lubricants also help promote engine
efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

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
and dipstick 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 flowability). Lower viscosity engine oils can
provide better fuel economy and cold weather performance, however, higher
viscosity engine 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 viscosity from the chart.

WARNING
When you return the rear seatback to
its upright position after being folded
down:
Be careful not to damage the seat belt
webbing or buckle. Do not allow the
seat belt webbing or buckle to get
caught or pinched in the rear seat.
Ensure that the seatback is completely
locked into its upright position by
pushing on the top of the seatback.
Otherwise, in an accident or sudden
stop, the seat could fold down and
allow cargo to enter the passenger
compartment, which could result in
serious injury or death.
NOTICE

[When returning the rear seatbacks
to the upright position, remember to
return the rear shoulder belts to their
proper position.

[Routing the seat belt webbing
through the rear seat belt guides will
help keep the seat belts from being
trapped behind or under the seats.
WARNING
Cargo
Cargo should always be secured to
prevent it from being thrown about the
vehicle in a collision and causing injury
to the vehicle occupants. Do not place
objects in the rear seats, since they
cannot be properly secured and may hit
the front seat occupants in a collision.
WARNING
Cargo loading
Make sure the engine is off, the
Automatic transmission/Dual clutch
transmission is in N (Neutral) or the
Manual transmission is in R (Reverse)
or the 1st gear, and the parking brake is
securely applied whenever loading or
unloading cargo. Failure to take these
steps may allow the vehicle to move if
the shift lever is inadvertently moved to
another position.

Whilst the engine is running, push either
of the switches to warm the driver’s seat
or front passenger’s seat.
During mild weather or under conditions
where the operation of the seat warmer
is not needed, keep the switches in the
OFF position.

[Each time you push the switch, the
temperature setting of the seat is
changed as follows:


OFFJHIGH ()JMIDDLE ()JLOW ()
K

[The seat warmer defaults to the OFF
position whenever the ignition switch
is turned on.

[When pressing the switch for more
than 1.5 seconds with the seat warmer
operating, the seat warmer will turn
OFF.
Rear Occupant Alert (ROA)
(if equipped)
Rear Occupant Alert is provided to help
prevent the driver from leaving the
vehicle with the rear passenger left in
the vehicle.
System setting
To use Rear Occupant Alert, it must be
enabled from the Settings menu in the
infotainment system screen. Select:

Safety system
The vehicles are equipped with a
Supplemental Air Bag System for the
driver’s seat and front passenger’s seats.
The front air bags are designed to
supplement the three-point seat belts.
For these air bags to provide protection,
the seat belts must be worn at all times
when driving.
You can be severely injured or killed
in an accident if you are not wearing
a seat belt. Air bags are designed to
supplement seat belts, but do not
replace them. Also, air bags are not
designed to deploy in every collision. In
some accidents, the seat belts are the
only restraint protecting you. WARNING
AIR BAG SAFETY PRECAUTIONS
ALWAYS use seat belts and Child
Restraint Systems - every trip, every
time, everyone! Even with air bags, you
can be seriously injured or killed in a
collision if you are improperly belted or
not wearing your seat belt when the air
bag inflates.
NEVER place a child in any Child
Restraint Systems or booster seat in the
front passenger seat. An inflating air
bag could forcefully strike the infant or
child causing serious or fatal injuries.
ABC - Always Buckle Children under
age 13 in the back seat. It is the safest
place for children of any age to ride. If
a child age 13 or older must be seated
in the front seat, he or she must be
properly belted and the seat should be
moved as far back as possible.
All occupants should sit upright with
the seatback in an upright position,
centred on the seat cushion with
their seat belt on, legs comfortably
extended and their feet on the floor
until the vehicle is parked and the
engine is turned off. If an occupant is
out of position during an accident, the
rapidly deploying air bag may forcefully
contact the occupant causing serious
or fatal injuries.
You and your passengers should never
sit or lean unnecessarily close to the air
bags or lean against the door or centre
console.
Move your seat as far back as possible
from front air bags, whilst still
maintaining control of the vehicle.
