2) Starting backward facing downhill
A) Brake pedal (both MT models and CVTmodels)
B) Clutch pedal (MT models only)
In both these cases, the Hill start assist
system operates under the following con- ditions.
.
when the clutch pedal is depressed
while the brake pedal is also depressed
(MT models)
. when the vehicle has stopped with the
brake pedal depressed (CVT models)
Braking power is maintained temporarily
(for approximately 2 seconds) by the Hill
start assist system after the brake pedal is
released. The driver is therefore able to
start the vehicle in the same way as on a
level grade, just using the clutch pedal
(MT models only) and accelerator pedal
(all models).
If the braking power of the Hill start assist
system is insufficient after the brake pedal
is released, apply more braking power by
depressing the brake pedal again.
The Hill start assist system may not
operate on slight grades. Also, the Hill
start assist system does not operate in the
following cases.
. when starting backward facing uphill
. when starting forward facing downhill
. while the parking brake is applied
. while the ignition switch is in the “ACC”
or “LOCK ”/“OFF ”position
. while the Hill start assist warning light/

WARNING
For CVT models, you can cancel the
cruise control by shifting the select
lever into the “N”position. However,
do not shift the lever into the “N”
position while driving except in case
of emergency. If the select lever is
shifted into the “N”position, the
engine brake will no longer work.
This could result in an accident.
The cruise control set indicator light in the combination meter turns off when the
cruise control is canceled.

The system notifies the driver of another
vehicle approaching from either side when
driving in reverse. This feature helps the
driver check the rear and side areas of the
vehicle when moving backward.
If the system detects a vehicle approach-
ing from either side while moving back-
ward, it warns the driver of dangers in the
following way.
.The BSD/RCTA approach indicator

WARNING
In a parking area in which the
parking lines are drawn diagonally
to driving lanes as indicated in the
illustration above, the system may
detect a vehicle (A) that is coming
across the front of your vehicle.
Also, the system may not detect a
vehicle (B) that is coming across
behind your vehicle. Always be sure
to check the surroundings with your
eyes when reversing the vehicle,
because the detectability of RCTA
is limited.

sudden stops or jolts, unsecured cargo
could be thrown around in the vehicle and
cause injury. Do not pile heavy loads on
the roof. Those loads raise the vehicle’s
center of gravity and make it more prone
to tip over.
. Never equip your vehicle with tires
larger than those specified in this manual.
! During driving
General precautions:
. Drive carefully. Do not take unneces-
sary risks by driving in dangerous areas or
over rough terrain.
. Slow down and employ extra caution at
all times. When driving off-road, you will
not have the benefit of marked traffic
lanes, banked curves, traffic signs and
the like.
. Do not drive across steep slopes.
Instead, drive either straight up or straight
down the slopes. A vehicle can much
more easily tip over sideways than it can
end over end. Avoid driving straight up or
down slopes that are too steep.
. Avoid sharp turning maneuvers, espe-
cially at higher speeds.
. Do not grip the inside or spokes of the
steering wheel. A bad bump could jerk the
wheel and injure your hands. Instead,
drive with your fingers and thumbs on
the outside of the rim. .
Do not drive or park over or near
flammable materials such as dry grass or
fallen leaves, as they may burn easily. The
exhaust system is very hot while the
engine is running and right after the
engine stops. This could create a fire
hazard.
Precautions when driving under espe-
cially dangerous situations:
. If driving through water, such as when
crossing shallow streams, first check the
depth of the water and the bottom of the
stream bed for firmness and ensure that
the bed of the stream is flat. Drive slowly
and cross the stream without stopping.
The water should be shallow enough that
it does not reach the vehicle’ s under-
carriage. Water entering the engine air
intake or the exhaust pipe or water
splashing onto electrical parts may da-
mage your vehicle and may cause it to
stall. Never attempt to drive through
rushing water; regardless of its depth, it
can wash away the ground from under
your tires, resulting in possible loss of
traction and even vehicle rollover.
. If you must rock the vehicle to free it
from sand or mud, depress the accelerator
pedal slightly and move the shift lever/
select lever back and forth between “1”/
“D ”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
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and CVT). For
CVT models, refer to “Selection of manual
mode ”F 7-26.
! After driving
. Always check your brakes for effec-
tiveness immediately after driving in sand,
mud or water. Do this by driving slowly
and stepping on the brake pedal. Repeat
that process several times to dry out the
brake discs and brake pads.
. After driving through tall grass, mud,
rocks, sand, rivers, etc., check that there
is no grass, bush, paper, rags, stones,
sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from
the underbody. If the vehicle is used with
these materials trapped or adhering to the
underbody, a mechanical breakdown or
fire could occur.
. Wash the vehicle’ s underbody after off-
road driving. Suspension components are
particularly prone to dirt buildup, so they
need to be washed thoroughly.

vehicle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine’s intake system and may
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
! Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blades are not frozen to the
windshield or rear window.
If the wiper blades are frozen to the
windshield or rear window, perform the
following procedure.
. To thaw the windshield wiper blades,
use the defroster with the airflow selection
in “
”and the temperature set for
maximum warmth until the wiper blades
are completely thawed. Refer to “Climate
control ”F 4-1.
. If your vehicle is equipped with a wiper
deicer, use it. It is helpful to thaw the
windshield wiper blades. Refer to “Defog-
ger and deicer ”F 3-108.
. To thaw the rear wiper blade, use the
rear window defogger. Refer to “Defoggerand deicer
”F 3-108.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield
despite wiper operation, use the defroster
with the airflow selection in “
”and the
temperature set for maximum warmth.
After the windshield gets warmed enough
to melt the frozen snow on it, wash it away
using the windshield washer. Refer to
“ Windshield washer ”F 3-98.
Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop
the vehicle at road side, use the hazard
warning flasher to alert other drivers.
Refer to “Hazard warning flasher ”F 3-8.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and freez-
ing temperatures. Blades of this type give
superior wiping performance in snowy
conditions. Be sure to use blades that
are suitable for your vehicle.
CAUTION
During high-speed driving, non-
freezing type wiper blades may not
perform as well as standard wiper
blades. If this happens, reduce the vehicle speed.
NOTE
When the season requiring non-freez-
ing type wiper blades is over, replace
them with standard wiper blades.

weight.
In addition, the total weight applied to
each axle (GAW) must never exceed the
GAWR. The front and rear GAWs can be
adjusted by relocating luggage inside the
vehicle.
Even if the total weight of your luggage is
lower than the vehicle capacity weight,
either front or rear GAW may exceed the
GAWR, depending on the distribution of
the luggage.
When possible, the load should be evenly
distributed throughout the vehicle.
If you carry heavy loads in the vehicle, you
should confirm that GVW and front and
rear GAWs are within the GVWR and
GAWR by putting your vehicle on a
vehicle scale, found at a commercial
weighing station.
Do not use replacement tires with a lower
load range than the originals because they
may lower the GVWR and GAWR limita-
tions. Replacement tires with a higher load
range than the originals do not increase
the GVWR and GAWR limitations.&Roof rail (if equipped)
1) Roof rail
2) Crossbar
Cargo can be carried on the roof after
securing the crossbars to the roof rails and
installing an appropriate carrying attach-
ment. When installing crossbars and a
carrying attachment, follow the manufac-
turer ’s instructions. The roof rail system is
designed to carry loads (cargo, crossbars
and carrying attachment) of no more than
150 lbs (68 kg) . Be sure not to exceed
your vehicle’ s GVWR and GAWR.
CAUTION
.When using a carrying attach-
ment, make sure that the total
carrying load of the cargo, cross- bars and carrying attachment
does not exceed 150 lbs (68 kg).
Overloading may cause damage
to the vehicle.
. For cargo carrying purposes, the
roof rails must be used together
with the crossbars and any ap-
propriate carrying attachment
that may be needed. The roof
rails must never be used alone to
carry cargo. Otherwise, damage
to the roof or paint, or a danger-
ous road hazard due to loss of
cargo could result.
NOTE
Remember that the vehicle ’s center of
gravity is altered with the weight of the
load on the roof, thus affecting driving
characteristics.
Drive carefully. Avoid rapid starts, hard
cornering and abrupt stops. Crosswind
effects will be increased.

&Roof molding and crossbar
(5-door models —if
equipped)
CAUTION
. For cargo carrying purposes, the
roof molding must be used to-
gether with a roof crossbar kit
and the appropriate carrying at-
tachment. Otherwise, damage to
the roof or paint or a dangerous
road hazard due to loss of cargo
could result.
. When using the roof crossbar kit,
make sure that the total weight of
the crossbars, carrying attach-
ment and cargo does not exceed
the maximum load limit. Over- loading may cause damage to
the vehicle and create a safety
hazard.
Cargo can be carried after securing the
roof crossbar kit to the roof molding and
installing the appropriate carrying attach-
ment. When installing the roof crossbar
kit, follow the manufacturer ’s instructions.
When you carry cargo on the roof using
the roof crossbar kit and a carrying
attachment, never exceed the maximum
load limit as explained below. You should
also be careful that your vehicle does not
exceed the Gross Vehicle Weight Rating
(GVWR) and front and rear Gross Axle
Weight Rating (GAWR). For information
about loading cargo into or onto your
vehicle, refer to “Loading your vehicle”
F 8-12. The maximum load limit of the
cargo, crossbars and carrying attachment
must not exceed 176 lbs (80 kg). Place
the heaviest load at the bottom, nearest
the roof, and evenly distribute the cargo.
Always properly secure all cargo. !
Installing carrying attachments on
the crossbars
When installing any carrying attachment
such as a bike carrier, ski carrier, kayak
carrier, cargo basket, etc. on the cross-
bars, follow the manufacturer ’s instruc-
tions and make sure that the attachment is
securely fixed to the crossbars. Use only
attachments designed specifically for the
crossbars. A set of the crossbars is
designed to carry loads (cargo and attach-
ment) of not more than 165 lbs (75 kg).
Before operating the vehicle, make sure
that the cargo is properly secured on the
attachment.
NOTE
Remember that the vehicle ’s center of
gravity is altered with the weight of the
load on the roof, thus affecting the
driving characteristics.
