1-7. Safety information
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering whee l hub, airbag cover and inflator), as
well as the front seats, apart from the front pillar and roof side rail may be hot for
several minutes, and the airbags themselves will be hot.
●The front windshield may crack.
■Operating conditions (front airbags)
●The SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col -
lision, when the vehicle imp acts
straight into a fixed barrier that does not move
or deform.
However, this threshold velocity will be considerably higher, if the vehicle strikes
a

n object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g., a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi -
cle is very close to the designed thresh ol
d level, the SRS front airbags and the
seat belt pretensioners ma y not activate together.
●The SRS front passenger airbag will not activate, if there is no passenger sitting
in the front passenger seat. However, th e front passenger airbag may deploy, if
luggage is put in the seat or the seat belt is buckled up, regardless of the pres -
ence of an occupant in the seat.
■Operating conditions (side and curtain shield airbags)
●The SRS side airbags and curtain shield airbags are designed to inflate, when
the passenger compartment is subjected to a severe impact from the side.
●The SRS side airbag on the passenger seat will not activate, if there is no passen -
ger sitting in the front passenger seat. Ho
wever, the side airbag on the passen-
ger seat may deploy, if luggage is put in the seat or the seat belt is buckled up,
r
egardless of the presence of the occupant in the seat.

Before driving
■Conditions under which the SRS airbags may deploy (inflate) other than a colli-
sion
The SRS front airbags may also deploy, if a se
rious impact occurs to the underside
of your vehicle. Some examples are shown in the illustration.
■Types of collisions that may not de ploy the SRS airbag (front airbags)
The SRS front airbags are generally not designed to inflate, if the vehicle is involved
i
n a side or rear collision, if it rolls over or if it is involved in a low-speed frontal colli -
sion. But, whenever a collision of any type c
auses sufficient forward deceleration of
the vehicle, deployment of th e SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or vehicle falling
●Collision from the side
●Collision from the rear
●Vehicle rollover

2-4. Using other driving systems
Electronically modulated air suspension
The vehicle adjusts the action of the shock absorbers and maintains vehicle
height automatically in response to driving conditions to help provide
enhanced driving comfort and vehicle control.
■ Vehicle height adjustment
Vehicle’s height is maintained at the se lected le
vel regardless of the num-
ber of occupants and luggage weight.

When driving
Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate for the
prevailing weather and roadway conditions.
■ Pre-winter preparations
●Use fluids appropriate to the p revailing outside temperatures.
• Engine oil
• Engine coolant
• Washer fluid
●Inspect the level and specific gravity of battery electrolyte.
●Have the vehicle fitted with four sno w tires or purchase a set of tire
chains for the rear tires.
Ensure that all tires are the same si
ze and brand, and that chains
match the size of the tires.
■ Befor
e driving the vehicle
Perform the following steps acco r
ding to the driving conditions.
●Do not forcibly try to open a window or move a wiper that has fro-
zen. Pour some warm water over the frozen area to melt the ice. 
Wipe away the water immediately to pr
event it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in front
of the windshield.
●Remove any ice that has accumulated on the vehicle chassis.
●Periodically check for and remove any excess ice or snow that may
accumulate in the wheel well or brakes.

When driving
• As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increas ed. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
• Avoid sudden braking as you may sk id, r
esulting in jackknifing and loss
of control. This is especially true on wet or slippery surfaces.
• Avoid jerky starts or sudden acceleration.
• Avoid jerky steering and sharp turn s, and slo
w down before making a
turn.
• Note that when making a turn, the tr ailer wheels will be closer than the
v
ehicle wheels to the inside of th e turn. Compensate by making a
larger than normal turning radius.
• Crosswinds and rough roads will ad v
ersely affect handling of your
vehicle and trailer, causing sway. Peri odically check the rear to prepare
for being passed by large trucks or buses, which may cause your vehi-
cle and trailer to sway. If s
waying occurs, firmly grip the steering wheel,
reduce speed immediately but gradually, and steer straight ahead.
Never increase speed. If you make no extreme correction with the
steering or brakes, your vehi cle and trailer will stabilize.
• Take care when passing other vehicl es. P
assing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
• In order to maintain efficient engine br
aking and electrical charging
performance, do not use overdrive. Transmission shift range position
must be in “4”, in the “S” mode.
• Due to the added load of the traile r
, your vehicle’s engine may overheat
on hot days (at temperatures over 85°F [30°C]) when driving up a
long or steep grade. If the engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. See “If your vehicle
overheats” ( P.359 ).
