Reverse Automatic Braking (RAB) System (If Equipped)
282
- There is an obstacle that is next
to an object.
- Going back along a wall.
- The area where the road starts
touching dirt and snow
- When reversing on an uneven
road.
 In circumstances such as the
following, it may not be possible to
avoid a collision even when the system
operates normally. - Roads are slippery.
- The tire air pressure is not
correct.
- The tires have become worn.
- Tire chains are installed.
- Tires which are not the desig-
nated size are installed.
- Emergency repairs were
performed using a puncture repair
kit.
- The suspension was modified.
- Vehicle driving is unstable due to
accident or malfunction.
- The brake warning light is illumi-
nated.
■ Sonar Audible Alarm func -
tionWhen Reverse Automatic Braking (RAB)
system is in operation, an audible warning
beeps will sound in 3 levels to warn the
driver of a potential collision.
NOTEIt may take time to display the wall and
sound warning beeps after the object
was recognized by the Sonar Audible
Alarm function.

Remember to drive with care at all times
regardless of the type of tires on your
vehicle.■ Tire Chains
NOTEWhen tire chains cannot be used, use
of another type of traction device
(such as spring chains) may be
acceptable if use on your vehicle is
recommended by the device manufac-
turer, taking into account tire size and
road conditions. Follow the device
manufacturer’s instructions, espe-
cially regarding maximum vehicle
speed.
To help avoid damage to your vehicle,
drive slowly, readjust or remove the
device if it is contacting your vehicle,
and do not spin your wheels. Damage
caused to your vehicle by use of a
traction device is not covered under
warranty.
Make certain that any traction device
you use is an SAE class S device, and use it on the rear wheels only. Always

use the utmost care when driving with
a traction device. Overconfidence
because you are using a traction
device could easily lead to a serious
accident.
■ Rocking the VehicleIf you must rock the v ehicle to free it from
snow, sand, or mud, depress the acceler-
ator pedal slightly and move the shift
lever/select lever back and forth between
“1” (MT model)/“D” (AT model) and “R”
repeatedly. Do not race the engine. For
the best possible traction, avoid spinning
the wheels when trying to free the vehicle.
When the road surface is extremely slip-
pery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than in 1st (MT models).
If your vehicle is a AT model, Snow mode
can be used. For details about how to use
the mode, refer to "Driving Mode Select
Switch (If Equipped)" P241.
8-9. Loading Your Vehicle
CAUTION
Tire chains cannot be used on your
vehicle because of the lack of clear-
ance between the tires and vehicle
body.
WARNING
Never allow passengers to ride on a
folded rear seatback or in the trunk.
Doing so may result in serious
injury.
WARNING
 Never stack luggage or other
cargo higher than the top of the
seatback because it could tumble
forward and injure passengers in
the event of a sudden stop or
accident. Keep luggage or cargo
low, as close to the floor as
possible.

Tires and Wheels
35811-21. Tires and Wheels■Types of TiresYou should be familiar with type of tires
present on your vehicle.
▼ Summer tires
The factory-installed tires on your new
vehicle are summer tires.
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-
covered or icy roads.
If you drive your vehicle on snow-covered
or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to
replace all four tires.
▼ All season tires
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road
conditions. However all season tires do
not offer as much traction performance as
winter (snow) tires in heavy or loose snow
or on icy roads. All season tires are identified by “ALL

SEASON” and/or “M+S” (Mud & Snow) on
the tire sidewall.
▼ Winter (snow) tires
Winter tires are best suited for driving on
snow-covered and icy roads. However
winter tires do not perform as well as
summer tires and all season tires on roads
other than snow-covered and icy roads.
NOTEIf the tread wears down below 0.16 in.
(4mm) on snow tires the effectiveness
of snow tires is lost.
▼ Low profile tires
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard tires. Be sure to
use snow tires or tire chains on snowy
and/or icy roads and drive carefully at a
speed appropriate for road and weather
conditions.NOTELow profile tires may cause greater
damage than usual to the wheel when
receiving impact from the road sur-
face. Therefore pay attention to the fol-
lowing: 
Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
 Avoid pot holes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
■ Tire Pressure Monitoring
System (TPMS) (If Equipped)The tire pressure monitoring system
provides the driver with a warning
message by sending a signal from a
sensor that is installed in each wheel
when tire pressure is severely low. The
tire pressure monitoring system will acti-
vate only when the vehicle is driven. Also,
this system may not react immediately to
a sudden drop in tire pressure (for
example, a blow-out caused by running
over a sharp object).
If you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to illuminate. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to pres-
sures higher than those shown on the tire
inflation pressure label. Specifically,
inflate them by an extra 1 psi (6.9 kPa,
0.07 kgf/cm
2) for every difference of 10°F
