instrument cluster may not be as
bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control 0 174 .
When it is bright enough outside,
the headlamps will turn off or may
change to Daytime Running
Lamps (DRL).
The automatic headlamp system
turns off when the exterior lamp
control is turned to

176 Lighting Entry Lighting with Approach
Detection
If equipped with approach detection,
the entry lighting feature will
automatically turn on when the RKE
transmitter is detected within
approximately 2 m (6 ft) of the

battery rundown protection system
automatically turns the lamp off after
some time.
Exterior Lighting Battery
Saver The exterior lamps turn off about
10 minutes after the ignition is
turned off, if the parking lamps or
headlamps have been manually left
on. This protects against draining
the battery. To restart the 10-minute
timer, turn the exterior lamp control
to the off position and then back to
the parking lamp or headlamp
position. To keep the lamps on for more than
10 minutes, the ignition must be in
the ACC/ACCESSORY or ON/RUN
position.

196 Driving and Operating Warning (Continued)After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road. 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. See Tires 0 299 .
.
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 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.
{ WarningUsing 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.
{ WarningCoasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.
.
Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.

202 Driving and Operating
Starting and
Operating New Vehicle Break-In Follow these recommended
guidelines during the first
2 400 km (1,500 mi) of driving this
vehicle. Parts have a break-in
period and performance will be
better in the long run.
For the first 2 400 km (1,500 mi):
.
Avoid full throttle starts and
abrupt stops.
.
Do not exceed 4000 engine rpm.
.
Avoid driving at any one
constant speed, fast or slow.
.
Avoid downshifting to brake or
slow the vehicle when the
engine speed will exceed
4000 rpm.
.
Do not let the engine labor.
Never lug the engine in high
gear at low speeds. .
Do not participate in track
events, sport driving schools,
or similar activities during this
break-in period.
.
Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2 400 km (1,500 mi).
.
To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first
300 km (200 mi). New tires do
not have maximum traction and
may tend to slip.
.
New brake linings also need a
break – in period. Avoid making
hard stops during the first
300 km (200 mi). This is
recommended every time brake
linings are replaced. Ignition Positions
The vehicle has an electronic
keyless ignition with pushbutton
start.
Pressing the button cycles it through
three modes: ACC/ACCESSORY,
ON/RUN/START, and Stopping the
Engine/OFF.
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interference

Driving and Operating 203to the Keyless Access system. See
Remote Keyless Entry (RKE)
System Operation 0 29 .
To shift out of P (Park), the vehicle
must be in ACC/ACCESSORY or
ON/RUN, and the brake pedal must
be applied.
Stopping the Engine/OFF (No
Indicator Lights) : When the
vehicle is stopped, press ENGINE
START/STOP once to turn the
engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) 0 206 .
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display a
message in the Driver Information
Center (DIC). See Transmission
Messages 0 156 . When the vehicle
is shifted into P (Park), the ignition
system will switch to OFF. Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady
pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral).
This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to
a safe location.
3. Come to a complete stop, shift
to P (Park), and turn off the
ignition.
4. Set the parking brake. See
Electric Parking Brake 0 214 .{ WarningTurning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold ENGINE START/
STOP for longer than two seconds,
or press twice in five seconds.
ACC/ACCESSORY (Amber
Indicator Light) : This mode allows
you to use some electrical
accessories when the engine is off.
With the ignition off, pressing the
button one time without the brake
pedal applied will place the ignition
system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after
five minutes to prevent battery
rundown.
