Hazardous driving conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
Drive cautiously and allow extra
distance for braking.
Avoid sudden braking or steering.
When braking with non-ABS brakes pump the brake pedal with
a light up-and-down motion until
the vehicle is stopped.
Do not pump the brake pedal on a
vehicle equipped with ABS. If stalled in snow, mud, or sand,
use the second gear. Accelerate
slowly to avoid spinning the drive
wheels.
Use sand, rock salt, or other non- slip material under the drive
wheels to provide traction when
stalled in ice, snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and any
forward gear in vehicles equipped
with an Automatic transmission/Dual
clutch transmission. Do not race the
engine, and spin the wheels as little
as possible. If you are still stuck after
a few tries, have the vehicle pulled
out by a tow vehicle to avoid engine
overheating and possible damage to
the transmission.
SPECIAL DRIVING CONDITIONS
WARNING- Downshifting
Do not downshift with an auto-
matic transmission while driv-
ing on slippery surfaces. The
sudden change in tire speed
could cause the tires to skid
and result in an accident.
WARNING- Sudden
Vehicle Movement
Do not attempt to rock the vehi-
cle if people or objects are near-
by. The vehicle may suddenly
move forward or backwards as it
becomes unstuck.

What to do in an emergency
6. Loosen the wheel lug nuts coun-terclockwise one turn each, but do
not remove any nut until the tire
has been raised off the ground.
7. Place the jack at the front (1) orrear (2) jacking position closest to
the tire you are changing. Place
the jack at the designated loca-
tions under the frame. The jacking
positions are plates welded to the
frame with two tabs and a raised
dot to line up with the jack. 8. Insert the wheel lug nut wrench
into the jack and turn it clockwise,
raising the vehicle until the tire just
clears the ground. This measure-
ment is approximately 1 in. (30
mm).
Before removing the wheel lug
nuts, make sure the vehicle is sta-
ble and that there is no chance for
movement or slippage.

Maintenance
Tire replacement
If the tire is worn evenly, a tread wear
Indicator (A) will appear as a solid
band across the tread. This shows
there is less than 1/16 inch (1.6 mm)
of tread left on the tire. Replace the
tire when this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.The ABS works by comparing the
speed of the wheels. The tire size
affects wheel speed. When replacing
tires, all 4 tires must use the same
size originally supplied with the vehi-
cle. Using tires of a different size can
cause the ABS (Anti-lock Brake
System) and ESC (Electronic
Stability Control) to work irregularly.
✽ ✽
NOTICE
• In order to maintain optimal driv-
ing performance, we recommend
replacing tires with the same spec-
ification and type as originally
installed in your vehicle. If not,
driving performance could be
altered.
• When replacing tires (or wheels), it is recommended to replace the
two front or two rear tires (or
wheels) as a pair.
Replacing just one tire can serious-
ly affect your vehicle's handling.
Compact spare tire replacement
(if equipped)
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.

bulbs
Handle halogen bulbs with care.
Halogen bulbs contain pres- surized gas that will produce
flying pieces of glass if bro-
ken.

(Continued)
Always handle them carefully,and avoid scratches and abra-
sions. If the bulbs are lit, avoid
contact with liquids. Never
touch the glass with bare
hands. Residual oil may cause
the bulb to overheat and burst
when lit. A bulb should be
operated only when installed
in a headlamp.
If a bulb becomes damaged or cracked, replace it immediate-
ly and carefully dispose of it.
Wear eye protection when changing a bulb. Allow the
bulb to cool down before han-
dling it.
