Fuel Range
Press the trip/fuel button until FUEL RANGE displays.
This display shows the approximate number of
remaining kilometers (km) or miles (mi) the vehicle
can be driven without refueling.
The fuel range estimate is based on an average of the
vehicle's fuel economy over recent driving history and
the amount of fuel remaining in the fuel tank. This
estimate will change if driving conditions change. For
example, if driving in traffic and making frequent stops,
this display may read one number, but if the vehicle is
driven on a freeway, the number may change even
though the same amount of fuel is in the fuel tank. This
is because different driving conditions produce different
fuel economies. Generally, freeway driving produces
better fuel economy than city driving.
If your vehicle is low on fuel, the FUEL LEVEL LOW
message will be displayed. See“FUEL LEVEL LOW”
under DIC Warnings and Messages
on page 4‑55for
more information.
Average Economy
Press the trip/fuel button until AVG ECONOMY
displays. This display shows the approximate average
liters per 100 kilometers (L/100 km) or miles per gallon
(mpg). This number is calculated based on the number
of L/100 km (mpg) recorded since the last time this
menu item was reset. To reset AVG ECONOMY, press
and hold the set/reset button. The display will return
to zero.
Instantaneous Economy
Press the trip/fuel button until INST ECONOMY
displays. This display shows the current fuel economy
at a particular moment and will change frequently as
driving conditions change. This display shows the
instantaneous fuel economy in liters per 100 kilometers
(L/100 km) or miles per gallon (mpg). Unlike average
economy, this screen cannot be reset.
Average Speed
Press the trip/fuel button until AVERAGE SPEED
displays. This display shows the average speed of the
vehicle in kilometers per hour (km/h) or miles per
hour (mph). This average is calculated based on the
various vehicle speeds recorded since the last reset
of this value. To reset the value, press and hold the
set/reset button. The display will return to zero.

ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help the
driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps
receiving updates on wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the time needed to
get a foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, there will not be enough time to apply the
brakes if that vehicle suddenly slows or stops. Always
leave enough room up ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down firmly and let antilock work. The antilock pump or
motor operating might be heard and the brake pedal
might be felt to pulsate, but this is normal.
Braking in Emergencies
ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more
than even the very best braking.
Brake Assist
This vehicle has a Brake Assist feature designed to
assist the driver in stopping or decreasing vehicle
speed in emergency driving conditions. This feature
uses the stability system hydraulic brake control module
to supplement the power brake system under conditions
where the driver has quickly and forcefully applied the
brake pedal in an attempt to quickly stop or slow down
the vehicle. The stability system hydraulic brake control
module increases brake pressure at each corner of the
vehicle until the ABS activates. Minor brake pedal
pulsations or pedal movement during this time is normal
and the driver should continue to apply the brake pedal
as the driving situation dictates The Brake Assist
feature will automatically disengage when the brake
pedal is released or brake pedal pressure is quickly
decreased.

Towing a Trailer
{WARNING:
The driver can lose control when pulling a trailer if
the correct equipment is not used or the vehicle is
not driven properly. For example, if the trailer is
too heavy, the brakes may not work well—or
even at all. The driver and passengers could be
seriously injured. The vehicle may also be
damaged; the resulting repairs would not be
covered by the vehicle warranty. Pull a trailer only
if all the steps in this section have been followed.
Ask your dealer for advice and information about
towing a trailer with the vehicle.
Notice: Pulling a trailer improperly can damage the
vehicle and result in costly repairs not covered by
the vehicle warranty. To pull a trailer correctly,
follow the advice in this section and see your dealer
for important information about towing a trailer with
the vehicle. The vehicle can tow a trailer if it is equipped with
the proper trailer towing equipment. To identify the
trailering capacity of the vehicle, read the information
in
“Weight of the Trailer” that appears later in this
section. Trailering is different than just driving the
vehicle by itself. Trailering means changes in handling,
acceleration, braking, durability and fuel economy.
Successful, safe trailering takes correct equipment, and
it has to be used properly.
The following information has many time-tested,
important trailering tips and safety rules. Many of these
are important for the safety of the driver and the
passengers. So please read this section carefully before
pulling a trailer.
Load-pulling components such as the engine,
transmission, axles, wheel assemblies and tires are
forced to work harder against the drag of the added
weight. The engine is required to operate at relatively
higher speeds and under greater loads, generating
extra heat. The trailer also adds considerably to wind
resistance, increasing the pulling requirements.
