CLIMATE CONTROL AIR FILTER
Filter inspection
If the vehicle is operated in severely
air-polluted cities or on dusty rough
roads for a long period, it should be
inspected more frequently and
replaced earlier. When you, the
owner, replace the climate control air
filter, replace it performing the follow-
ing procedure, and be careful to
avoid damaging other components.
Replace the filter according to the
Maintenance Schedule.
Install a new climate control air fil-
ter in the correct direction with the
arrow symbol (
↓) facing down-
wards.
Otherwise, the climate control
effects may decrease, possibly
with a noise.
Filter replacement
1.With the glove box open, remove
the stoppers on both sides.
2.Open the glove box and remove
the support strap (1).3.Remove the climate control air fil-
ter case whilst pressing the lock on
the left side of the cover.
4.Replace the climate control air fil-
ter.
5.Reassemble in the reverse order of
disassembly.

Maintenance
Do not allow the wiper arm to fall
against the windscreen, since it
may chip or crack the wind-
CAUTION
WIPER BLADES
Blade inspection
Information
Commercial hot waxes applied by
automatic car washes have been
known to make the windscreen
difficult to clean.Contamination of either the wind-
screen or the wiper blades with for-
eign matter can reduce the effective-
ness of the windscreen wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the wind-
screen and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water.
To prevent damage to the wiper
blades, do not use petrol,
kerosene, paint thinner, or other
solvents on or near them.
Blade replacement
When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.
To prevent damage to the wiper
arms or other components, do not
attempt to move the wipers manu-
ally.
The use of a non-specified wiper
blade could result in wiper mal-
function and failure.

BATTERY
For best battery service
• Keep the battery securely mounted.
• Keep the battery top clean and dry.
• Keep the terminals and connec-
tions clean, tight, and coated with
petroleum jelly or terminal grease.
• Rinse any spilled electrolyte from
the battery immediately with a
solution of water and baking soda.
• If the vehicle is not going to be
used for an extended time, discon-
nect the battery cables.

Battery dangers
Always read the follow-
ing instructions carefully
when handling a battery.
Keep lighted cigarettes
and all other flames or
sparks away from the
battery.
Hydrogen, a highly com-
bustible gas, is always
present in battery cells
and may explode if ignit-
ed.
Keep batteries out of the
reach of children because
batteries contain highly
corrosive SULFURIC
ACID. Do not allow bat-
tery acid to contact your
skin, eyes, clothing or
paint finish.
(Continued)
WARNING (Continued)
If any electrolyte gets
into your eyes, flush
your eyes with clean
water for at least 15 min-
utes and get immediate
medical attention. If elec-
trolyte gets on your skin,
thoroughly wash the
contacted area. If you
feel a pain or a burning
sensation, get medical
attention immediately.
Wear eye protection
when charging or work-
ing near a battery.
Always provide ventila-
tion when working in an
enclosed space.
An inappropriately dis-
posed battery can be
harmful to the environ-
ment and human health.
Dispose of the battery
according to your local
law(s) or regulation.

model name of battery
2. 12V : The nominal voltage

•When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak, resulting in per-
sonal injury. Lift with a battery
carrier or with your hands on
opposite corners.
•Never attempt to recharge the
battery when the battery
cables are connected.
•The electrical ignition system
works with high voltage.
Never touch these compo-
nents with the engine running
or the ignition switch is in the
on position.
Failure to follow the above
warnings can result in serious
bodily injury or death.
If you connect unauthorised
electronic devices to the bat-
tery, the battery may be dis-
charged. Never use unautho-
rised devices.

Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
in a short time (because, for exam-
ple, the headlamps or interior
lamps were left on whilst the vehi-
cle was not in use), recharge it by
slow trickle (charging) for 10 hours.
• If the battery gradually discharges
because of high electric load whilst
the vehicle is being used, recharge
it at 20-30A for 2 hours.When recharging the battery,
observe the following precau-
tions:
•The battery must be removed
from the vehicle and placed in
an area with good ventilation.
•Do not allow cigarettes, sparks,
or flames near the battery.
•Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin gassing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 49°C (120°F).
•Wear eye protection when
checking the battery during
charging.
(Continued)
WARNING (Continued)
•Disconnect the battery charg-
er in the following order.
1. Turn off the battery charger
main switch.
2. Unhook the negative clamp
from the negative battery
terminal.
3. Unhook the positive clamp
from the positive battery
terminal.
•Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and stop the engine.
•The negative battery cable
must be removed first and
installed last when the battery
is disconnected.

TYRES AND WHEELS
Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tyre infla-
tion pressures
All tyre pressures (including the
spare) should be checked when the
tyres are cold. “Cold Tyres” means the
vehicle has not been driven for at
least 3 hours or driven less than 1.6
km.
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tyre wear.
For recommended inflation pressure
refer to “Tyre and wheels” in section
8.All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.Tyre underinflation
Severe underinflation (70 kPa
(10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tyre failures that can
result in the loss of vehicle con-
trol leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.
