• Do not add unnecessary accessories to
the exterior of your vehicle, for example
running boards. If you use a roof rack,
remember to fold it down or remove it
when not in use.
• Do not shift into neutral when you are
braking or when your vehicle is slowing
down.
• Shut all windows when driving at high
speeds.
• Switch off all electric systems when not
in use, for example air conditioning. Make
sure that you unplug any accessories
from the auxiliary power points when not
in use.
DRIVING THROUGH SHALLOW
WATER
WARNING: Do not attempt to cross
a deep or flowing body of water. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.Note:Driving through standing water can
cause vehicle damage.
Note:Engine damage can occur if water
enters the air filter.
Before driving through standing water, check
the depth. Never drive through water that is
higher than the bottom of the front rocker
area of your vehicle.
66E266447
When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction could
be limited. After driving through water and
as soon as it is safe to do so:• Lightly press the brake pedal to dry the
brakes and to check that they work.
• Turn the steering wheel to check that the
steering power assist works.
Check the function of the following:
• Horn
• Exterior lights
FLOOR MATS
WARNING: Use a floor mat designed
to fit the footwell of your vehicle that does
not obstruct the pedal area. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.
WARNING: Pedals that cannot move
freely can cause loss of vehicle control and
increase the risk of serious personal injury.

Driving Hints

Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.
Note:Dispose of used coolant in the
appropriate manner.
Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
Severe Climates
If you drive in extremely cold climates:
• It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection.
• Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• A coolant concentration of 40% provides
improved overheat protection.
• Coolant concentrations below 40%
decrease the overheat and corrosion
protection characteristics of the coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.
Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
460).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and a
message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
• Engine power is limited.
• The air conditioning system turns off.
406
Maintenance

If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.
You may notice a reduction in vehicle speed
caused by reduced engine power in order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to stop your vehicle. You can
continue to drive.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1. Stop your vehicle as soon as it is safe to
do so. Fully apply the parking brake, shift
into park (P) or neutral (N).
2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, follow the remaining steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the
engine and continue.AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See Scheduled
Maintenance (page 579).
The automatic transmission does not have
a transmission fluid dipstick.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.
Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.
