Messages on page 5-42. See your
dealer if there is a problem.
Curve Tips
.Take curves at a reasonable
speed.
.Reduce speed before entering a
curve.
.Maintain a reasonable steady
speed through the curve.
.Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.There are some situations when
steering around a problem may
be more effective than braking.
.Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
a hand.
.The Antilock Brake System
(ABS) allows steering while
braking.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:
1. Ease off the accelerator and then, if there is nothing in the
way, steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.

7576293) - 2015 - crc - 10/31/14
Driving and Operating 9-5
.Steering or Cornering Skid—
too much speed or steering in a
curve causes tires to slip and
lose cornering force.
.Acceleration Skid —too much
throttle causes the driving
wheels to spin.
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
.Ease your foot off the
accelerator pedal and steer the
way you want the vehicle to go.
The vehicle may straighten out.
Be ready for a second skid if it
occurs.
.Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other material on the road. Learn to
recognize warning clues
—such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt.
.Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes help
avoid only the braking skid.
Track Events and
Competitive Driving
Participating in track events or other
competitive driving without following
the instructions provided may affect
the vehicle warranty. See the
warranty manual before using the
vehicle for racing or other
competitive driving.
Refer to Competitive Driving Mode
on page 9-44. Be sure to follow all service
procedures before driving the
vehicle at track events or
competitively.
Engine Oil
{Caution
If the vehicle is used for track
events and competitive driving,
the engine may use more oil than
it would with normal use. Low oil
levels can damage the engine.
Check the oil level often and
maintain the proper level. See
Engine Oil on page 10-12.
{Caution
Not changing the engine oil to
15W-50 may cause engine
damage. Engine oil must be
changed to 15W-50 synthetic.
See
Capacities and Specifications
on page 12-2.

9-12 Driving and Operating
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10-47.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
(Continued)
Warning (Continued)
loss of steering. Always have the
engine running and the vehicle
in gear.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
.Be alert on top of hills;
something could be in your lane
(stalled car, accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.

or other things that can burn.
Active Fuel Management®
This system allows the engine to
operate on either all or half of its
cylinders, depending on the driving
conditions. With a manual
transmission, the system is only
active in Eco mode. With an
automatic transmission, the system
is available in all modes, but is more
aggressive in Eco mode. See Driver
Mode Control on page 9-40.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the vehicle to achieve better fuel
economy. When greater power
demands are required, such as
accelerating from a stop, passing,
or merging onto a freeway, the
system will maintain full-cylinder
operation.

9-34 Driving and Operating
If the vehicle is not upshifted as the
engine speed approaches fuel shut
off rpm, the engine speed will be
limited to protect the engine. See
Tachometer on page 5-12.
Active Rev Match
Vehicles equipped with a manual
transmission have Active Rev Match
(ARM). ARM aids in smoother
shifting by matching the engine
speed to the next selected gear. By
monitoring shift lever and clutch
operation, ARM adjusts engine
speed to match a calibrated value
based on gear selection. On
upshifts and downshifts, engine
speed will be increased and
decreased to match vehicle road
speed and transmission gear
position. ARM is maintained for a
few seconds between shifts, then
deactivates if the shift is not
completed.
The system is activated and
deactivated by pressing either of the
paddles marked REV MATCH on
the steering wheel. The system
must be activated with each new
ignition cycle.
A gear indicator in the instrument
cluster displays the current gear
selected:
.When ARM is activated, the
gear number is amber.
.When ARM is deactivated, the
gear number is white.
.A white dash indicates that
service is required. ARM will be
disabled, and the malfunction
indicator lamp will be on. See
Malfunction Indicator Lamp on
page 5-18. The clutch and
manual transmission will
continue to operate normally.
ARM will also:
.Be active above 32 km/h
(20 mph).
.Match engine speed up to
5400 rpm.
.Not operate when the
accelerator pedal is applied.
.Be disabled when the coolant
temperature is below 0°C (32°F).
