Cargo net (Canada only)GWarning!
Make sure the cargo net is properly engaged
at top and bottom position and the tightening
belts are securely fastened.
Never use a damaged cargo net.
Always use cargo net when transporting
cargo. This helps to avoid personal injury from
smaller objects being thrown around in the
occupant compartment during a collision or
sudden maneuver.
The cargo net cannot prevent the movement
of large, heavier objects into the passenger
compartment in an accident. Such items must
be properly secured using the cargo tie-down
rings in the cargo compartment floor.
Passenger use of seats behind installed cargo
net is restricted because of the footwell being
taken up by the net.
Use of the cargo net is a particularly
important safety factor when the vehicle is
loaded higher than the top of the seat
backrests with smaller objects. For your
safety, always use the cargo net when
transporting cargo.
The cargo net can be installed behind the
B-pillar or the C-pillar.
RWith the cargo volume expanded
(Y page 189), use holders : behind
B-pillars and the cargo tie-down rings
behind the front seats (Y page 188).
RWithout the cargo volume expanded, use
holders ; behind C-pillars and the cargo
tie-down rings in the cargo compartment
(Y page 188).

Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
Check the tire inflation pressure at least once
a month.
Check and adjust the tire inflation pressure
when the tires are cold ( Y page 219).
Checking tire inflation pressure
manually
Follow the steps below to achieve correct tire
inflation pressure:
XRemove the cap from the valve on one tire.XFirmly press a tire gauge onto the valve.XRead the tire inflation pressure on the tire
gauge and check against the
recommended tire inflation pressure on the
Tire and Loading Information placard on the
driver’s door B-pillar ( Y page 227). If
necessary, add air to achieve the
recommended tire inflation pressure.XIf you have overfilled the tire, release tire
inflation pressure by pushing the metal
stem of the valve with e.g. a tip of a pen.
Then recheck the tire inflation pressure
with the tire gauge.XInstall the valve cap.XRepeat this procedure for each tire.
Tire pressure loss warning system
(Canada only)
While the vehicle is being driven, the tire
pressure loss warning system monitors the
set tire inflation pressures by evaluating each
wheel’s rotational speed. This allows the
system to detect a significant loss of pressure
in a tire. If a wheel’s rotational speed changes
due to falling tire inflation pressure, you will
see a corresponding warning message in the
multifunction display.
The tire pressure loss warning system may
function in a restricted manner or with a delay
R when snow chains are mounted to the
vehicle
R in the presence of ice and snow
R when you are driving on a loose surface
(e.g. sand or gravel)
R when you are driving in a very sporty
manner (involving rapid acceleration or
high speeds in curves)
R when you are driving with a loaded roof
rack or heavily laden vehicleGWarning!
When the multifunction display shows the
message Check Tire Pressure Soon , one
or more of your tires are significantly
underinflated. You should stop and check
your tires as soon as possible, and inflate
them to the proper tire inflation pressure as
indicated on the vehicle’s Tire and Loading
Information placard or, if available, on the tire
inflation pressure label.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure. Underinflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Each tire, including the spare, should be
checked at least once a month when cold.
Inflate the tires to the recommended tire
inflation pressure as specified on
R the Tire and Loading Information placard on
the driver’s door B-pillar
or
R the tire inflation pressure label located on
the inside of the fuel filler flap

Load identification
iFor illustration purposes only. Actual data
on tires are specific to each vehicle and
may vary from data shown in above

In addition to the load index, special load
identification : may be molded into the tire
sidewall following the letter designating the
speed symbol B (Y page 235).
RNo specification given: absence of any text
(like in above example) indicates a
standard load (SL) tire.
RXL or Extra Load: designates an extra load

with the maximum load a tire can carry at
a specified pressure.
DOT, Tire Identification Number (TIN)
U.S. tire regulations require each new tire
manufacturer or tire retreader to mold a TIN
into or onto a sidewall of each tire produced.
The TIN is a unique identifier. The TIN
facilitates efforts by tire manufactures to
notify purchasers in recall situations or other
safety matters concerning tires. It gives
purchasers the means to easily identify such
tires.
The TIN is comprised of “Manufacturer’s
identification mark” ;, “Tire size” =, “Tire
type code” ? and “Date of manufacture”
A.

Tire type code
Tire type code ? may, at the option of the
manufacturer, be used as a descriptive code
for identifying significant characteristics of
the tire.
Date of manufacture
The date of manufacture A identifies the
week and year of manufacture.
The first two figures identify the week,
starting with “01” to represent the first full
week of the calendar year. The second two
figures represent the year.
For example, “3208” represents the 32nd
week of 2008.
